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

Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000385- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +0000386 file position when calling `truncate()`. It would previously change the file
387 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000388 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

Georg Brandlba83f822010-03-14 09:50:54 +0000392- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
393 class used to represent files stored inside an archive. The new
394 implementation is significantly faster and can be wrapped in a
395 ``io.BufferedReader`` object for more speedups. It also solves an issue
396 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
397 Patch by Nir Aides.

405 when the release file is empty.
Benjamin Petersona43f34c2010-01-25 03:31:13 +0000406
Georg Brandlba83f822010-03-14 09:50:54 +0000407- Issue #7748: Since unicode values are supported for some metadata options in
408 Distutils, the DistributionMetadata get_* methods will now return an utf-8
409 encoded string for them. This ensures that the upload and register commands
410 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +0000681- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
682 decimal string that's guaranteed to round back to x under correct rounding
683 (with round-half-to-even rounding mode). Previously it gave a string based on
684 rounding x to 17 decimal digits. repr(x) for a complex number behaves
685 similarly. On platforms where the correctly-rounded strtod and dtoa code is
686 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000687
Georg Brandlba83f822010-03-14 09:50:54 +0000688- Issue #7117: On almost all platforms: float-to-string and string-to-float
689 conversions within Python are now correctly rounded. Places these conversions
690 occur include: str for floats and complex numbers; the float and complex
691 constructors; old-style and new-style numeric formatting; serialization and
692 deserialization of floats and complex numbers using marshal, pickle and json;
693 parsing of float and imaginary literals in Python code; Decimal-to-float
694 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000695
Georg Brandlba83f822010-03-14 09:50:54 +0000696 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
697 providing correctly-rounded strtod and dtoa C functions. This code is
698 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
699 the C compiler. There may be a small number of platforms on which correct
700 operation of this code cannot be guaranteed, so the code is not used: notably,
701 this applies to platforms where the C double format is not IEEE 754 binary64,
702 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
703 and Python's configure script is unable to determine how to change the FPU
704 precision. On these platforms conversions use the platform strtod and dtoa,
705 as before.

Georg Brandlba83f822010-03-14 09:50:54 +0000707- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
708 uses the correctly-rounded string <-> float conversions described above (when
709 available), and so produces correctly rounded results that will display nicely
710 under the float repr. There are two related small changes: (1) round now
711 accepts any class with an ``__index__()`` method for its second argument (but
712 no longer accepts floats for the second argument), and (2) an excessively
713 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
714 raises an exception.

862 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
863 but with at least one decimal point and with a default precision
864 of 12. Previously, the behavior the same but with a default precision of 6.
865 This more closely matches ``str()``, and reduces surprises when adding
866 alignment flags to the empty presentation type. This also affects the new
867 complex.__format__ in the same way.

987
Georg Brandlba83f822010-03-14 09:50:54 +0000988- Issue #4935: The overflow checking code in the expandtabs() method common to
989 str, bytes and bytearray could be optimized away by the compiler, letting the
990 interpreter segfault instead of raising an error.
Antoine Pitrouc2f02212009-01-13 23:13:52 +0000991
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +0000992- Issue #3720: Fix a crash when an iterator modifies its class and removes its

1000 collecting the oldest generation) so that allocating lots of objects without
1001 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +00001002 Martin von Löwis at

1006
Georg Brandlba83f822010-03-14 09:50:54 +00001007- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
1008 existing .py counterpart, override the co_filename attributes of all code
1009 objects if the original filename is obsolete (which can happen if the file has
1010 been renamed, moved, or if it is accessed through different paths). Patch by
1011 Ziga Seilnacht and Jean-Paul Calderone.
Antoine Pitroue96d4ea2009-01-06 18:10:47 +00001012

Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +00001015- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
1016 file with `str' filename on Windows.
1017
Antoine Pitrouaa687902009-01-01 14:11:22 +00001018- Issue #3680: Reference cycles created through a dict, set or deque iterator

Nick Coghlan180e4002008-12-30 01:18:48 +00001023
Benjamin Peterson7af65562008-12-29 17:56:58 +00001024- Issue #4764: With io.open, IOError.filename is set when trying to open a

1029
Georg Brandl6425a2f2008-12-28 11:54:53 +00001030- Issue #4759: None is now allowed as the first argument of
Georg Brandlba83f822010-03-14 09:50:54 +00001031 ``bytearray.translate()``. It was always allowed for ``bytes.translate()``.
Georg Brandl6425a2f2008-12-28 11:54:53 +00001032
Skip Montanarof205c132008-12-23 03:30:15 +00001033- Added test case to ensure attempts to read from a file opened for writing
1034 fail.
1035
Georg Brandlba83f822010-03-14 09:50:54 +00001036- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always print
1037 elapsed times, not only when some objects are uncollectable/unreachable.
1038 Original patch by Neil Schemenauer.

Georg Brandlba83f822010-03-14 09:50:54 +00001050- Issue #4445: Replace ``sizeof(PyStringObject)`` with
1051 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
1052 instances. On a typical machine this saves 3 bytes of memory (on average) per
1053 string allocation.
Mark Dickinson826f3fe2008-12-05 21:55:28 +00001054
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00001055- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1056 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1057 instead of throwing a MemoryError.
1058
Georg Brandlba83f822010-03-14 09:50:54 +00001059- Issue #3689: The list reversed iterator now supports __length_hint__ instead
1060 of __len__. Behavior now matches other reversed iterators.
Raymond Hettinger7989a4d2008-12-03 15:42:10 +00001061
Benjamin Petersonc078f922008-11-21 22:27:24 +00001062- Issue #4367: Python would segfault during compiling when the unicodedata
1063 module couldn't be imported and \N escapes were present.
1064
Georg Brandlba83f822010-03-14 09:50:54 +00001065- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
1066 file objects with closefd=False. The file descriptor is still kept open but
1067 the file object behaves like a closed file. The ``FileIO`` object also got a
1068 new readonly attribute ``closefd``.
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +00001069
Benjamin Peterson46cc6d12008-11-19 21:49:09 +00001070- Issue #4348: Some bytearray methods returned that didn't cause any change to
1071 the bytearray, returned the same bytearray instead of a copy.
1072
Georg Brandlba83f822010-03-14 09:50:54 +00001073- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.

1076
Benjamin Peterson6624a9f2008-11-03 15:14:51 +00001077- Issue #4048: The parser module now correctly validates relative imports.
1078
Benjamin Petersondcee09d2008-10-31 02:16:05 +00001079- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1080 exec statement.
1081
Georg Brandlba83f822010-03-14 09:50:54 +00001082- Issue #4176: Fixed a crash when pickling an object which ``__reduce__`` method

Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +00001084
Benjamin Petersonbdca9422008-10-26 20:21:13 +00001085- Issue #4209: Enabling unicode_literals and the print_function in the same
1086 __future__ import didn't work.
1087
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00001088- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00001089 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00001090
Georg Brandlba83f822010-03-14 09:50:54 +00001091- On windows, ``os.chdir()`` given unicode was not working if
1092 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
1093 this code path is really executed because I cannot move to such directory on
1094 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00001095
Georg Brandlba83f822010-03-14 09:50:54 +00001096- Issue #4069: When ``set.remove(element)`` is used with a set element, the
1097 element is temporarily replaced with an equivalent frozenset. But the
1098 eventual KeyError would always report the empty ``frozenset()`` as the missing
1099 key. Now it correctly refers to the initial element.

Gregory P. Smith2b3eb372009-04-05 23:48:26 +00001116- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
1117 returned them on 64bit platforms.
1118
Walter Dörwalded960ac2009-05-03 22:36:33 +00001119- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
1120 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1121 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1122 of using the replace error handler in PyUnicode_DecodeUTF8().
1123
Walter Dörwald726ba8e2009-05-06 14:32:35 +00001124- Issue #3739: The unicode-internal encoder now reports the number of characters
1125 consumed like any other encoder (instead of the number of bytes).
1126
Georg Brandlba83f822010-03-14 09:50:54 +00001127- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
1128 allocator will be automatically disabled when running under Valgrind. This
1129 gives improved memory leak detection when running under Valgrind, while taking
1130 advantage of pymalloc at other times.

2354 threads could return successfully while some Thread objects were still
2355 referenced. This also introduces a new private function: ``thread._count()``.

Georg Brandlba83f822010-03-14 09:50:54 +00002374 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip

2496
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002497- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2498 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2499 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2500 ``printf`` function, whereas PyString_FromFormat has an independent
2501 implementation and uses "%zd" on all platforms for size_t values.
2502 This makes a difference on win64, where ``printf`` needs "%Id" to display
2503 64bit values.

2509 object; previously an int would be returned for small values. the __long__

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002520 was correctly parsed but parsing of subsequent arguments failed.

Vinay Sajip35e3b032008-09-01 14:33:59 +00002522- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002523 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2524 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2525 when given a tuple of classes as second argument, were looking up
2526 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2527 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002666What's New in Python 2.6 beta 3?
2667================================
2668
Barry Warsaw07a4a382008-08-21 01:15:08 +00002669*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002670
2671Core and Builtins
2672-----------------
2673
Guido van Rossumf8402962008-08-20 15:01:50 +00002674- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2675 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2676 extensions do not automatically benefit from the class attribute
2677 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2678 to their tp_flags field if they care. This is a backwards
2679 compatibility feature; in 3.0, all types will use the cache by
2680 default.
2681
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002682- Keyword arguments can now follow starred arguments. (``f(a, *args,
2683 keyword=23)`` is now valid syntax.)
2684
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002685- ctypes function pointers that are COM methods have a boolean True
2686 value again.
2687
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002688- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2689 by denying s# to parse objects that have a releasebuffer procedure,
2690 and introducing s*.
2691
Georg Brandl1e13ea92008-08-11 09:07:59 +00002692- Issue #3537: Fix an assertion failure when an empty but presized dict
2693 object was stored in the freelist.
2694
Mark Dickinsonb6467572008-08-04 21:30:09 +00002695- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2696 ValueError consistently across platforms.
2697
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002698- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2699 (64bit Unix, for example), unichr() would truncate its argument and return
2700 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2701
Neal Norwitze7d8be82008-07-31 17:17:14 +00002702- Apply security patches from Apple.
2703
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002704- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2705 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2706
Antoine Pitrou92f82162008-07-25 22:22:08 +00002707- Issue #1819: function calls with several named parameters are now on
2708 average 35% faster (as measured by pybench).
2709
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002710- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2711 the python debugger steps into a class statement: the free variables (local
2712 variables defined in an outer scope) would be deleted from the outer scope.
2713
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002714- Issue #2620: Overflow checking when allocating or reallocating memory
2715 was not always being done properly in some python types and extension
2716 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2717 all been updated to perform better checks and places in the code that
2718 would previously leak memory on the error path when such an allocation
2719 failed have been fixed.
2720
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002721Library
2722-------
2723
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002724- Issue #3612: Added some missing basic types in ctypes.wintypes.
2725
Benjamin Petersone977ad42008-08-20 01:42:01 +00002726- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2727 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2728
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002729- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2730 version reported by these tools does not necessarily follow the python
2731 version numbering scheme, so the module is less strict when parsing it.
2732
Nick Coghlanf70385a2008-08-18 12:42:46 +00002733- Issue #2235: Added Py3k warnings for types which will become unhashable
2734 under the stricter __hash__ inheritance rules in 3.0. Several types
2735 which did not meet the rules for hash invariants and were already
2736 unhashable in 3.0 have now been explicitly flagged as unhashable in
2737 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2738 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2739
Brett Cannon88f801d2008-08-18 00:46:22 +00002740- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2741 imported into the module but exposed as part of the module's API.
2742
Brett Cannon7b96f072008-08-18 00:41:11 +00002743- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2744
Brett Cannon46225e72008-08-18 00:36:52 +00002745- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
2746
Brett Cannon25c9d6a2008-08-17 22:10:11 +00002747- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2748
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002749- Issue #3575: Incremental decoder's decode function now takes bytearray
2750 by using 's*' instead of 't#'.
2751
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002752- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002753 fails unicode conversion on 2nd parameter. (windows only)
2754
Facundo Batista94f243a2008-08-17 03:38:39 +00002755- Issue 2464. urllib2 now supports a malformation in the URL received
2756 in a redirect.
2757
Brett Cannonabe423e2008-08-16 21:47:07 +00002758- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002759 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002760
Facundo Batistaeb90b782008-08-16 14:44:07 +00002761- Issue #2776: fixed small issue when handling an URL with double slash
2762 after a 302 response in the case of not going through a proxy.
2763
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002764- Issue #2676: in the email package, content-type parsing was hanging on
2765 pathological input because of quadratic or exponential behaviour of a
2766 regular expression.
2767
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002768- Issue #3476: binary buffered reading through the new "io" library is now
2769 thread-safe.
2770
Brett Cannonbf3157b2008-08-14 05:00:03 +00002771- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2772 since mimetools itself is deprecated. Because modules are cached, all
2773 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2774
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002775- Issue #3134: shutil referenced undefined WindowsError symbol.
2776
Robert Schuppenies14646332008-08-10 11:01:53 +00002777- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2778 menu entries were not deleted.
2779
Brett Cannon83e81842008-08-09 23:30:55 +00002780- Copied the implementation of reduce() to _functools.reduce() to have a
2781 version that did not raise a DeprecationWarning under -3.
2782
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002783- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2784 a MemoryError rather than silently stop the iteration.
2785
Guido van Rossum59ce9012008-08-09 14:55:34 +00002786- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2787 to _sre.compile() will now be rejected. This should not affect anybody
2788 since the re.compile() function never generates invalid re-bytecode.
2789
Skip Montanaroa032bf42008-08-08 22:52:51 +00002790- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2791 upon first access it can be automatically initialized from the csv file if
2792 it wasn't initialized during instantiation.
2793
Brett Cannon3aa2a492008-08-06 22:28:09 +00002794- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2795 the reload() built-in has been removed.
2796
Brett Cannon7e30b672008-08-04 21:52:25 +00002797- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002798 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

2801 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
2802 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
2803 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00002804
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00002805- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
2806 raised an AttributeError.
2807
Benjamin Peterson01a24322008-07-28 23:35:27 +00002808- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002809 asking for a specific length. This problem only affected files opened
2810 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002811
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00002812- Issue #3449: Update decimal module to use most recent specification
2813 (v. 1.68) and tests (v. 2.58) from IBM.
2814
Skip Montanarof9ac43f2008-07-27 00:50:41 +00002815- Issue 3437: Bug fix in robotparser parsing of Allow: lines.

2823
2824- Issue #3303: Fix a crash in locale.strcoll() when calling it with
2825 invalid arguments.
2826
2827- Issue #3302: Fix several crashes when calling locale's gettext functions
2828 with None arguments.
2829
2830- Issue #3389: Allow resolving dotted names for handlers in logging
2831 configuration files.
2832
2833- Deprecate the sunaudio module for removal in Python 3.0.
2834
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002835- Issue #3394: zipfile.writestr sets external attributes when passed a
2836 file name rather than a ZipInfo instance, so files are extracted with
2837 mode 0600 rather than 000 under Unix.
2838
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002839- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2840 argument in python 2.5, this broke code that subclassed Popen to include its
2841 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00002851- Issue #2235: the C API function PyObject_HashNotImplemented and its
2852 interaction with the tp_hash slot (added in 2.6b2) are now documented
2853
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002854- Issue #643841: The language reference now provides more detailed
2855 coverage of the lookup process for special methods. The disclaimers
2856 regarding lack of coverage of new-style classes have also been
2857 removed, since the coverage is now fairly reasonable.

2862
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002863*Release date: 17-Jul-2008*

2866-----------------
2867
Georg Brandl3e483f62008-07-16 22:57:41 +00002868- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2869 its methods now allow for items objects that can be converted to
2870 an integer using operator.index().
2871
Mark Dickinson64b7e502008-07-16 09:40:03 +00002872- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2873 produced a ValueError instead of giving the correct float.
2874
Eric Smitha5fa5a22008-07-16 00:11:49 +00002875- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2876 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2877
Mark Dickinson7103aa42008-07-15 19:08:33 +00002878- Issue #3008: the float type has a new instance method 'float.hex'
2879 and a new class method 'float.fromhex' to convert floating-point
2880 numbers to and from hexadecimal strings, respectively.
2881
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002882- Issue #2235: __hash__ is once again inherited by default. To allow
2883 collections.Hashable to remain meaningful in the presence of the
2884 default hash implementation (object.__hash__), it is now possible
2885 to explicit block inheritance of hash by setting __hash__=None at
2886 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2887 level.
2888
Nick Coghlanb028f502008-07-13 14:52:36 +00002889- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2890 the parent module cannot be found while performing an absolute import.
2891 This means that an incorrectly defined __package__ attribute will
2892 now only prevent relative imports in that module rather than causing
2893 all imports from that module to fail.
2894
Nick Coghlan14ff9942008-07-08 14:21:42 +00002895- Issue #2517: Allow unicode messages in Exceptions again by correctly
2896 bypassing the instance dictionary when looking up __unicode__ on
2897 new-style classes.
2898
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002899- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2900 set to a custom object whose write() method happens to install
2901 another file in sys.stdout.

2905 another thread's dictionary.
2906
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002907- Issue #3004: Minor change to slice.indices(): the start and stop
2908 arguments are now treated identically, making the behaviour easier
2909 to describe and understand. For example, slice(None, -10,
2910 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2911 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2912 10, -1).
2913
Georg Brandl278fc502008-07-19 12:46:12 +00002914- Issue #3219: Calling a function with repeated keyword arguments,

Georg Brandl5cc774e2008-06-11 20:28:06 +00003366 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003367
3368 This is controlled by the configure argument ``--with-universal-archs``:
3369
3370 - ``--with-universal-archs=all``: install 4-way universal
3371
3372 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3373
3374 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3375
3376 This option should be used in combination with ``--enable-universalsdk=``.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003428- Issue #1631171: Re-implement the 'warnings' module in C (the
3429 original Python code has been kept as backup). This will allow for
3430 using the 'warning's machinery in such places as the parser where
3431 use of pure Python code is not possible. Both the ``showarning()``
3432 and ``formatwarning()`` gain an optional 'line' argument which is
3433 not called by default for backwards-compatibility reasons. Setting
3434 ``warnings.showwarning()`` to an implementation that lacks support
3435 for the ``line`` argument will raise a DeprecationWarning.

3489
Georg Brandl3ee81df2008-05-17 18:14:43 +00003490- Issue #2385: distutils.core.run_script() makes __file__ available,
3491 so the controlled environment will more closely mirror the typical
3492 script environment. This supports setup.py scripts that refer to
3493 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003498- Issue #2550: The approach used by client/server code for obtaining
3499 ports to listen on in network-oriented tests has been refined in an
3500 effort to facilitate running multiple instances of the entire
3501 regression test suite in parallel without issue.
3502 test_support.bind_port() has been fixed such that it will always
3503 return a unique port -- which wasn't always the case with the
3504 previous implementation, especially if socket options had been set
3505 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3506 new implementation of bind_port() will actually raise an exception
3507 if it is passed an AF_INET/SOCK_STREAM socket with either the
3508 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3509 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3510 the socket it's been passed. This currently only applies to
3511 Windows. This option prevents any other sockets from binding to the
3512 host/port we've bound to, thus removing the possibility of the
3513 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3514 when a second SOCK_STREAM socket binds and accepts to a host/port
3515 that's already been bound by another socket. The optional preferred
3516 port parameter to bind_port() has been removed. Under no
3517 circumstances should tests be hard coding ports!
3518
3519 test_support.find_unused_port() has also been introduced, which will
3520 pass a temporary socket object to bind_port() in order to obtain an
3521 unused port. The temporary socket object is then closed and
3522 deleted, and the port is returned. This method should only be used
3523 for obtaining an unused port in order to pass to an external program
3524 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3525 a parameter to a server-oriented class that doesn't give you direct
3526 access to the underlying socket used.
3527
3528 Finally, test_support.HOST has been introduced, which should be used
3529 for the host argument of any relevant socket calls (i.e. bind and
3530 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003531
3532 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003533 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003534 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3535 test_asynchat and test_socket_ssl.
3536
Georg Brandl3ee81df2008-05-17 18:14:43 +00003537 It is now possible for multiple instances of the regression test
3538 suite to run in parallel without issue.

3804Core and builtins
3805-----------------
3806
Fred Drakea8ee94b2008-03-01 02:45:07 +00003807- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003808 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00003809
Georg Brandlad61bc82008-02-23 15:11:18 +00003810- Issue #2067: file.__exit__() now calls subclasses' close() method.
3811
3812- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003813
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003814- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003815 issue 215555 for a discussion.
3816
Eric Smitha73fbe72008-02-23 03:09:44 +00003817- Added the future_builtins module, which contains hex() and oct().
3818 These are the PEP 3127 version of these functions, designed to be
3819 compatible with the hex() and oct() builtins from Python 3.0. They
3820 differ slightly in their output formats from the existing, unchanged
3821 Python 2.6 builtins. The expected usage of the future_builtins
3822 module is:
3823 from future_builtins import hex, oct
3824
Eric Smith7ef40bf2008-02-20 23:34:22 +00003825- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3826 exponents for exponents with absolute value < 100. Follows C99
3827 standard. This is a change on Windows, which would use 3 digits.
3828 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3829 so that any alterations it does to the resulting string will be
3830 available in stringlib/formatter.h (for float.__format__).
3831
Eric Smith5a3c1352008-02-19 13:21:56 +00003832- Implemented PEP 3101, Advanced String Formatting. This adds a new
3833 builtin format(); a format() method for str and unicode; a
3834 __format__() method to object, str, unicode, int, long, float, and
3835 datetime; the class string.Formatter; and the C API
3836 PyObject_Format().
3837
Georg Brandl3ee81df2008-05-17 18:14:43 +00003838- Fixed several potential crashes, all caused by specially crafted
3839 __del__ methods exploiting objects in temporarily inconsistent
3840 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003841
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003842- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003843 prevent a possible crash: an Abstract Base Class would try to access
3844 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003845
Georg Brandl3ee81df2008-05-17 18:14:43 +00003846- Fixed repr() and str() of complex numbers with infinity or nan as
3847 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003848
Georg Brandl3ee81df2008-05-17 18:14:43 +00003849- Clear all free lists during a gc.collect() of the highest generation
3850 in order to allow pymalloc to free more arenas. Python may give back
3851 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003852
Georg Brandl3ee81df2008-05-17 18:14:43 +00003853- Issue #2045: Fix an infinite recursion triggered when printing a
3854 subclass of collections.defaultdict, if its default_factory is set
3855 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003856
Christian Heimesf75dbef2008-02-08 00:11:31 +00003857- Fixed a minor memory leak in dictobject.c. The content of the free
3858 list was not freed on interpreter shutdown.
3859
Georg Brandl21e99f42010-03-07 15:23:59 +00003860- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003861 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003862
Georg Brandl3ee81df2008-05-17 18:14:43 +00003863- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3864 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003865 to compact the internal free lists of pre-allocted ints and floats.
3866
Georg Brandl3ee81df2008-05-17 18:14:43 +00003867- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3868 calls. Python expected the return type int but the fork familie
3869 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003870
Georg Brandl3ee81df2008-05-17 18:14:43 +00003871- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3872 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003873
Georg Brandl3ee81df2008-05-17 18:14:43 +00003874- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3875 with the collections.Sequence API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003880- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3881 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003882
Georg Brandl3ee81df2008-05-17 18:14:43 +00003883- Patch #1473257: generator objects gain a gi_code attribute. This is
3884 the same object as the func_code attribute of the function that
3885 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003886
Georg Brandl3ee81df2008-05-17 18:14:43 +00003887- Issue #1920: "while 0" statements were completely removed by the
3888 compiler, even in the presence of an "else" clause, which is
3889 supposed to be run when the condition is false. Now the compiler
3890 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003891
Guido van Rossumeead05f2008-01-24 18:21:02 +00003892- A few crashers fixed: weakref_in_del.py (issue #1377858);
3893 loosing_dict_ref.py (issue #1303614, test67.py);
3894 borrowed_ref_[34].py (not in tracker).
3895
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003896- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003897 suppressed while an extension is loaded by calling SetErrorMode in
3898 dynload_win.c. The error is still reported properly.
3899
Georg Brandl3ee81df2008-05-17 18:14:43 +00003900- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003901 several extension methods and modules do not work without unicode
3902 support.
3903
Georg Brandl26543b12008-01-21 18:36:51 +00003904- Issue #1882: when compiling code from a string, encoding cookies in the
3905 second line of code were not always recognized correctly.
3906
Georg Brandl14404b62008-01-19 19:27:05 +00003907- Issue #1679: "0x" was taken as a valid integer literal.
3908
Georg Brandl6caad7d2008-01-26 14:19:22 +00003909- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003910 added.
3911
Christian Heimesc94e2b52008-01-14 04:13:37 +00003912- sys.float_info / PyFloat_GetInfo: The floating point information
3913 object was converted from a dict to a specialized structseq object.
3914
Georg Brandl3ee81df2008-05-17 18:14:43 +00003915- Patch #1816: Added sys.flags structseq. It exposes the status of
3916 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003917
Georg Brandl3ee81df2008-05-17 18:14:43 +00003918- Objects/structseq.c: Implemented new structseq representation. The
3919 patch makes structseqs (e.g. the return value of os.stat) more
3920 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003921
Georg Brandl3ee81df2008-05-17 18:14:43 +00003922- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00003944 and INF. float("nan"), float("inf") and float("-inf") now work on
3945 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003946
Georg Brandl3ee81df2008-05-17 18:14:43 +00003947- Compiler now generates simpler and faster code for dictionary
3948 literals. The oparg for BUILD_MAP now indicates an estimated
3949 dictionary size. There is a new opcode, STORE_MAP, for adding
3950 entries to the dictionary.

Georg Brandl21e99f42010-03-07 15:23:59 +00003994- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003995 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3996 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003997
Georg Brandl3ee81df2008-05-17 18:14:43 +00003998- Issue #1686386: Tuple's tp_repr did not take into account the
3999 possibility of having a self-referential tuple, which is possible
4000 from C code. Nor did object's tp_str consider that a type's tp_str
4001 could do something that could lead to an inifinite recursion.
4002 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4003 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004004
Georg Brandl3ee81df2008-05-17 18:14:43 +00004005- Issue #1164: It was possible to trigger deadlock when using the
4006 'print' statement to write to a file since the GIL was not released
4007 as needed. Now PyObject_Print() does the right thing along with
4008 various tp_print implementations of the built-in types and those in
4009 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004010
Georg Brandl3ee81df2008-05-17 18:14:43 +00004011- Issue #1147: Exceptions were directly allowing string exceptions in
4012 their throw() method even though string exceptions no longer
4013 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004014
Georg Brandl3ee81df2008-05-17 18:14:43 +00004015- Issue #1096: Prevent a segfault from getting the repr of a very
4016 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004017
Brett Cannon1e534b52007-09-07 04:18:30 +00004018- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004019 PyObject_Call() never calling back out to Python code to trigger
4020 recursion depth updates/checks. Required the creation of a static
4021 RuntimeError instance in case normalizing an exception put the
4022 recursion check value past its limit. Fixes crashers
4023 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004024

Neal Norwitz0ac60192007-05-27 04:08:54 +00004038- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004039 __*__ attributes. (Some already existed, e.g., __doc__ and
4040 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004041
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004042- Add -3 option to the interpreter to warn about features that are
4043 deprecated and will be changed/removed in Python 3.0.
4044
Georg Brandl2134e752007-05-21 20:34:16 +00004045- Patch #1686487: you can now pass any mapping after '**' in function
4046 calls.
4047
Collin Winter62903052007-05-18 23:11:24 +00004048- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004049 "except E as target:". This is to provide forwards compatibility
4050 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004051
Brett Cannon229cee22007-05-05 01:34:02 +00004052- Deprecate BaseException.message as per PEP 352.

Vinay Sajip8549ce32007-05-06 17:53:37 +00004057- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004058 setting a plain string, ie don't expand to single letter identifiers.
4059
Raymond Hettinger13936692007-04-11 18:40:58 +00004060- Request #1191699: Slices can now be pickled.
4061
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004062- Request #1193128: str.translate() now allows a None argument for
4063 translations that only remove characters without re-mapping the
4064 remaining characters.
4065
Georg Brandl5cb76c12007-03-21 09:00:39 +00004066- Patch #1682205: a TypeError while unpacking an iterable is no longer

4070
Guido van Rossum143b5642007-03-23 04:58:42 +00004071- Bug #1683368: The object.__init__() and object.__new__() methods are
4072 now stricter in rejecting excess arguments. The only time when
4073 either allows excess arguments is when it is not overridden and the
4074 other one is. For backwards compatibility, when both are
4075 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004076 warning later). Also, type.__init__() insists on the same signature
4077 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004078
Georg Brandl3ee81df2008-05-17 18:14:43 +00004079- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4080 object to complex using its __complex__() method before falling back
4081 to the __float__() method. Therefore, the functions in the cmath
4082 module now can operate on objects that define a __complex__()
4083 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004084
Georg Brandl3ee81df2008-05-17 18:14:43 +00004085- Patch #1623563: allow __class__ assignment for classes with

4087 same slot names.

4093 ``object.__reduce_ex__()`` is called with an object that is faking
4094 its type.

4100
Georg Brandl7b9c5552007-03-12 14:30:05 +00004101- Bug #1678647: write a newline after printing an exception in any
4102 case, even when converting the value to a string failed.
4103
Georg Brandl871f1bc2007-03-12 13:17:36 +00004104- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004105 its argument, if it exists. If not, it will work like before. This
4106 allows customizing the output of dir() in the presence of a
4107 __getattr__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00004115- Patch #1491866: change the complex() constructor to allow
4116 parthensized forms. This means complex(repr(x)) now works instead of
4117 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004118
Georg Brandlaa2321b2007-03-07 00:40:28 +00004119- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004120 makes the filenames the warning module prints much more sensible
4121 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004122

Georg Brandl0fca97a2007-03-05 22:28:08 +00004134- Patch #1674228: when assigning a slice (old-style), check for the
4135 sq_ass_slice instead of the sq_slice slot.
4136
Georg Brandl3ee81df2008-05-17 18:14:43 +00004137- When printing an unraisable error, don't print exceptions. before
4138 the name. This duplicates the behavior whening normally printing
4139 exceptions.

4767 -- the failure just occurred later, with a more cumbersome
4768 exception.

4981 partial fix for Bug #1574584.
4982
Georg Brandl3ee81df2008-05-17 18:14:43 +00004983- Fix turtle so that time.sleep is imported for the entire library.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005049- Issue #829951: In the smtplib module, SMTP.starttls() now complies
5050 with RFC 3207 and forgets any knowledge obtained from the server not
5051 obtained from the TLS negotiation itself. Patch contributed by Bill
5052 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00005053
Georg Brandl3ee81df2008-05-17 18:14:43 +00005054- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005055 that the SMTP.starttls() caller no longer needs to call ehlo()
5056 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00005057 does not claim to support starttls. Adds the
5058 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
5059 Fenner.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005113- itertools.chain() now has an alternate constructor,

5139 complex, tuple, list, dict, set, and frozenset. Formerly, it would
5140 silently miscode subclasses of those types. Now, it raises a
5141 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00005142

Georg Brandl3ee81df2008-05-17 18:14:43 +00005157 time so that opening a database previously created with the DB_DUP
5158 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5159 opens. Specifically: dictionary assignment to a DB object will
5160 replace all values for a given key when the database allows
5161 duplicate values. DB users should use DB.put(k, v) when they want
5162 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005163

5169 characters with ASCII value less than 32. Also, it correctly quotes
5170 dots only if they occur on a single line, as opposed to the previous
5171 behavior of quoting dots if they are the second character of any
5172 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00005173

5495-----
5496
Georg Brandl3ee81df2008-05-17 18:14:43 +00005497- Unified naming convention for free lists and their limits. All free
5498 lists in Object/ are named ``free_list``, the counter ``numfree``
5499 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
5500 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00005501
Georg Brandl3ee81df2008-05-17 18:14:43 +00005502- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5503 to ``PyTuple_SetItem``, it can be used to populate a brand new
5504 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00005505
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005506- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

5509 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
5510 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005511
5512- Patch #1720595: add T_BOOL to the range of structmember types.
5513
5514- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
5515 ``PyFloat_GetInfo()`` to the float API.
5516
Georg Brandl3ee81df2008-05-17 18:14:43 +00005517- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5518 of w# format code incorrectly truncated the length to an int, even
5519 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5520 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005521
Georg Brandl3ee81df2008-05-17 18:14:43 +00005522- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
5523 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005525- PEP 3123: Provide forward compatibility with Python 3.0, while
5526 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
5527 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005528
Georg Brandl3ee81df2008-05-17 18:14:43 +00005529- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
5530 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005531
5532- Patch #1733960: Allow T_LONGLONG to accept ints.

5539
5540- Fix some leftovers from the conversion from int to Py_ssize_t
5541 (relevant to strings and sequences of more than 2**31 items).
5542
5543- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5544 outside of pystate.c and should not be necessary.
5545
Georg Brandl3ee81df2008-05-17 18:14:43 +00005546- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5547 absolute imports. In earlier versions they might have used relative
5548 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005549
Georg Brandl3ee81df2008-05-17 18:14:43 +00005550- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5551 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005552
Georg Brandl3ee81df2008-05-17 18:14:43 +00005553- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
5554 macro so it can be used as an expression.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005560- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
5561 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
5562 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
5563 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00005564

Georg Brandl3ee81df2008-05-17 18:14:43 +00005578- Removed the macfs module. It had been deprecated since Python 2.5.
5579 This lead to the deprecation of macostools.touched() as it relied
5580 solely on macfs and was a no-op under OS X.
