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

297 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +0000298 library would return a bogus result; on Solaris, it was possible to crash the

313 and add the additional members returned in an OSVERSIONINFOEX structure. The
314 new members are service_pack_major, service_pack_minor, suite_mask, and
315 product_type.

Georg Brandlba83f822010-03-14 09:50:54 +0000317- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
318 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
319 returning NULL. The macro now returns a statically allocated empty string
320 instead.

330 strings,
331 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
332 numeric strings corresponding to subnormal values,
333 (3) a memory leak for some values large enough to cause overflow, and
334 (4) a number of flaws that could lead to incorrectly rounded results.

Antoine Pitroud840e512010-02-04 20:20:18 +0000362- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +0000363 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +0000364 Also, raise ValueError rather than TypeError when an unknown TIPC address
365 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000369- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +0000370 file position when calling `truncate()`. It would previously change the file
371 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000372 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
373
Benjamin Petersone06f7112010-01-28 02:15:02 +0000374- UserDict is now a new-style class.
375
Georg Brandlba83f822010-03-14 09:50:54 +0000376- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
377 class used to represent files stored inside an archive. The new
378 implementation is significantly faster and can be wrapped in a
379 ``io.BufferedReader`` object for more speedups. It also solves an issue
380 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
381 Patch by Nir Aides.

389 when the release file is empty.
Benjamin Petersona43f34c2010-01-25 03:31:13 +0000390
Georg Brandlba83f822010-03-14 09:50:54 +0000391- Issue #7748: Since unicode values are supported for some metadata options in
392 Distutils, the DistributionMetadata get_* methods will now return an utf-8
393 encoded string for them. This ensures that the upload and register commands
394 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +0000396- Issue #1670765: Prevent ``email.generator.Generator`` from re-wrapping
R. David Murrayed44dfa2010-01-16 05:15:17 +0000397 headers in multipart/signed MIME parts, which fixes one of the sources of

470
Georg Brandlba83f822010-03-14 09:50:54 +0000471- The ``__complex__()`` method is now looked up on the class of instances to
472 make it consistent with other special methods.

476
Mark Dickinson1b34d252010-01-01 17:27:30 +0000477- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000478 DeprecationWarning when passed a float argument where an integer was expected.
479 These functions and methods now raise TypeError instead. The majority of the
480 effects of this change are in the extension modules, but some core functions
481 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
482 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +0000665- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
666 decimal string that's guaranteed to round back to x under correct rounding
667 (with round-half-to-even rounding mode). Previously it gave a string based on
668 rounding x to 17 decimal digits. repr(x) for a complex number behaves
669 similarly. On platforms where the correctly-rounded strtod and dtoa code is
670 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000671
Georg Brandlba83f822010-03-14 09:50:54 +0000672- Issue #7117: On almost all platforms: float-to-string and string-to-float
673 conversions within Python are now correctly rounded. Places these conversions
674 occur include: str for floats and complex numbers; the float and complex
675 constructors; old-style and new-style numeric formatting; serialization and
676 deserialization of floats and complex numbers using marshal, pickle and json;
677 parsing of float and imaginary literals in Python code; Decimal-to-float
678 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000679
Georg Brandlba83f822010-03-14 09:50:54 +0000680 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
681 providing correctly-rounded strtod and dtoa C functions. This code is
682 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
683 the C compiler. There may be a small number of platforms on which correct
684 operation of this code cannot be guaranteed, so the code is not used: notably,
685 this applies to platforms where the C double format is not IEEE 754 binary64,
686 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
687 and Python's configure script is unable to determine how to change the FPU
688 precision. On these platforms conversions use the platform strtod and dtoa,
689 as before.

Georg Brandlba83f822010-03-14 09:50:54 +0000691- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
692 uses the correctly-rounded string <-> float conversions described above (when
693 available), and so produces correctly rounded results that will display nicely
694 under the float repr. There are two related small changes: (1) round now
695 accepts any class with an ``__index__()`` method for its second argument (but
696 no longer accepts floats for the second argument), and (2) an excessively
697 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
698 raises an exception.

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

Georg Brandlba83f822010-03-14 09:50:54 +0000991- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
992 existing .py counterpart, override the co_filename attributes of all code

1048
Georg Brandlba83f822010-03-14 09:50:54 +00001049- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
1050 file objects with closefd=False. The file descriptor is still kept open but
1051 the file object behaves like a closed file. The ``FileIO`` object also got a
1052 new readonly attribute ``closefd``.

Benjamin Peterson399b1fe2008-10-25 02:53:28 +00001072- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00001075- On windows, ``os.chdir()`` given unicode was not working if
1076 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
1077 this code path is really executed because I cannot move to such directory on
1078 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00001080- Issue #4069: When ``set.remove(element)`` is used with a set element, the
1081 element is temporarily replaced with an equivalent frozenset. But the
1082 eventual KeyError would always report the empty ``frozenset()`` as the missing
1083 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00001103- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
1104 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1105 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1106 of using the replace error handler in PyUnicode_DecodeUTF8().
1107
Walter Dörwald726ba8e2009-05-06 14:32:35 +00001108- Issue #3739: The unicode-internal encoder now reports the number of characters

1110
Georg Brandlba83f822010-03-14 09:50:54 +00001111- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
1112 allocator will be automatically disabled when running under Valgrind. This
1113 gives improved memory leak detection when running under Valgrind, while taking
1114 advantage of pymalloc at other times.

2345 __all__ attribute, rather than using a hardcoded and incomplete list.
2346
R. David Murray14dcd432009-10-14 13:58:07 +00002347- Issue #7058: Added save/restore for things like sys.argv and cwd to
2348 runtest_inner in regrtest, with warnings if the called test modifies them,
2349 and a new section in the summary report at the end.

Guilherme Polo7f146ab2009-06-21 17:22:50 +00002356- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
2357 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00002358 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
2359 the tests if DISPLAY is defined but can't be used.

2363
Georg Brandlba83f822010-03-14 09:50:54 +00002364- Issue #5354: New test support function import_fresh_module() makes it easy to
2365 import both normal and optimised versions of modules. test_heapq and
2366 test_warnings have been adjusted to use it, tests for other modules with both
2367 C and Python implementations in the stdlib can be adjusted to use it over
2368 time.

Georg Brandlba83f822010-03-14 09:50:54 +00002376- regrtest no longer treats ImportError as equivalent to SkipTest. Imports that
2377 should cause a test to be skipped are now done using import_module from test
2378 support, which does the conversion.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002479- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2480
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002481- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2482 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2483 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2484 ``printf`` function, whereas PyString_FromFormat has an independent
2485 implementation and uses "%zd" on all platforms for size_t values.
2486 This makes a difference on win64, where ``printf`` needs "%Id" to display
2487 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00002489- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

2493 object; previously an int would be returned for small values. the __long__
2494 method is allowed to return either an int or a long, but the behaviour of
2495 float objects should not change to respect backward compatibility.

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002497- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +00002503 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002504 was correctly parsed but parsing of subsequent arguments failed.
2505
Vinay Sajip35e3b032008-09-01 14:33:59 +00002506- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002507 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2508 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2509 when given a tuple of classes as second argument, were looking up
2510 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2511 type object.
2512
Neal Norwitz18aa3882008-08-24 05:04:52 +00002513- Fix crashes on memory allocation failure found with failmalloc.

Martin v. Löwisab0b29b2008-09-13 08:11:57 +00002639- Issue #3833: Use a different upgrade code for Win64 installers.
2640
Martin v. Löwis3f5fda82008-09-08 13:50:10 +00002641- Issue #2271: Set SecureCustomProperties so that installation will properly
2642 use the TARGETDIR even for unprivileged users.
2643
Martin v. Löwis67543a92008-09-08 12:02:45 +00002644- Allow passing the MSI file name to merge.py.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002650What's New in Python 2.6 beta 3?
2651================================
2652
Barry Warsaw07a4a382008-08-21 01:15:08 +00002653*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002654
2655Core and Builtins
2656-----------------
2657
Guido van Rossumf8402962008-08-20 15:01:50 +00002658- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2659 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2660 extensions do not automatically benefit from the class attribute
2661 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2662 to their tp_flags field if they care. This is a backwards
2663 compatibility feature; in 3.0, all types will use the cache by
2664 default.
2665
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002666- Keyword arguments can now follow starred arguments. (``f(a, *args,
2667 keyword=23)`` is now valid syntax.)
2668
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002669- ctypes function pointers that are COM methods have a boolean True
2670 value again.
2671
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002672- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2673 by denying s# to parse objects that have a releasebuffer procedure,
2674 and introducing s*.
2675
Georg Brandl1e13ea92008-08-11 09:07:59 +00002676- Issue #3537: Fix an assertion failure when an empty but presized dict
2677 object was stored in the freelist.
2678
Mark Dickinsonb6467572008-08-04 21:30:09 +00002679- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2680 ValueError consistently across platforms.
2681
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002682- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2683 (64bit Unix, for example), unichr() would truncate its argument and return
2684 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2685
Neal Norwitze7d8be82008-07-31 17:17:14 +00002686- Apply security patches from Apple.
2687
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002688- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2689 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2690
Antoine Pitrou92f82162008-07-25 22:22:08 +00002691- Issue #1819: function calls with several named parameters are now on
2692 average 35% faster (as measured by pybench).
2693
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002694- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2695 the python debugger steps into a class statement: the free variables (local
2696 variables defined in an outer scope) would be deleted from the outer scope.
2697
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002698- Issue #2620: Overflow checking when allocating or reallocating memory
2699 was not always being done properly in some python types and extension
2700 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2701 all been updated to perform better checks and places in the code that
2702 would previously leak memory on the error path when such an allocation
2703 failed have been fixed.
2704
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002705Library
2706-------
2707
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002708- Issue #3612: Added some missing basic types in ctypes.wintypes.
2709
Benjamin Petersone977ad42008-08-20 01:42:01 +00002710- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2711 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2712
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002713- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2714 version reported by these tools does not necessarily follow the python
2715 version numbering scheme, so the module is less strict when parsing it.
2716
Nick Coghlanf70385a2008-08-18 12:42:46 +00002717- Issue #2235: Added Py3k warnings for types which will become unhashable
2718 under the stricter __hash__ inheritance rules in 3.0. Several types
2719 which did not meet the rules for hash invariants and were already
2720 unhashable in 3.0 have now been explicitly flagged as unhashable in
2721 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2722 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2723
Brett Cannon88f801d2008-08-18 00:46:22 +00002724- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2725 imported into the module but exposed as part of the module's API.
2726
Brett Cannon7b96f072008-08-18 00:41:11 +00002727- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2728
Brett Cannon46225e72008-08-18 00:36:52 +00002729- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
2730
Brett Cannon25c9d6a2008-08-17 22:10:11 +00002731- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2732
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002733- Issue #3575: Incremental decoder's decode function now takes bytearray
2734 by using 's*' instead of 't#'.
2735
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002736- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002737 fails unicode conversion on 2nd parameter. (windows only)
2738
Facundo Batista94f243a2008-08-17 03:38:39 +00002739- Issue 2464. urllib2 now supports a malformation in the URL received
2740 in a redirect.
2741
Brett Cannonabe423e2008-08-16 21:47:07 +00002742- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002743 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002744
Facundo Batistaeb90b782008-08-16 14:44:07 +00002745- Issue #2776: fixed small issue when handling an URL with double slash
2746 after a 302 response in the case of not going through a proxy.
2747
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002748- Issue #2676: in the email package, content-type parsing was hanging on
2749 pathological input because of quadratic or exponential behaviour of a
2750 regular expression.
2751
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002752- Issue #3476: binary buffered reading through the new "io" library is now
2753 thread-safe.
2754
Brett Cannonbf3157b2008-08-14 05:00:03 +00002755- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2756 since mimetools itself is deprecated. Because modules are cached, all
2757 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2758
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002759- Issue #3134: shutil referenced undefined WindowsError symbol.
2760
Robert Schuppenies14646332008-08-10 11:01:53 +00002761- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2762 menu entries were not deleted.
2763
Brett Cannon83e81842008-08-09 23:30:55 +00002764- Copied the implementation of reduce() to _functools.reduce() to have a
2765 version that did not raise a DeprecationWarning under -3.
2766
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002767- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2768 a MemoryError rather than silently stop the iteration.
2769
Guido van Rossum59ce9012008-08-09 14:55:34 +00002770- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2771 to _sre.compile() will now be rejected. This should not affect anybody
2772 since the re.compile() function never generates invalid re-bytecode.
2773
Skip Montanaroa032bf42008-08-08 22:52:51 +00002774- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2775 upon first access it can be automatically initialized from the csv file if
2776 it wasn't initialized during instantiation.
2777
Brett Cannon3aa2a492008-08-06 22:28:09 +00002778- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2779 the reload() built-in has been removed.
2780
Brett Cannon7e30b672008-08-04 21:52:25 +00002781- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002782 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00002783 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
2784 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
2785 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
2786 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
2787 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00002788
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00002789- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
2790 raised an AttributeError.
2791
Benjamin Peterson01a24322008-07-28 23:35:27 +00002792- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002793 asking for a specific length. This problem only affected files opened
2794 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002795
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00002796- Issue #3449: Update decimal module to use most recent specification
2797 (v. 1.68) and tests (v. 2.58) from IBM.
2798
Skip Montanarof9ac43f2008-07-27 00:50:41 +00002799- Issue 3437: Bug fix in robotparser parsing of Allow: lines.

2807
2808- Issue #3303: Fix a crash in locale.strcoll() when calling it with
2809 invalid arguments.
2810
2811- Issue #3302: Fix several crashes when calling locale's gettext functions
2812 with None arguments.
2813
2814- Issue #3389: Allow resolving dotted names for handlers in logging
2815 configuration files.
2816
2817- Deprecate the sunaudio module for removal in Python 3.0.
2818
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002819- Issue #3394: zipfile.writestr sets external attributes when passed a
2820 file name rather than a ZipInfo instance, so files are extracted with
2821 mode 0600 rather than 000 under Unix.
2822
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002823- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2824 argument in python 2.5, this broke code that subclassed Popen to include its
2825 own poll method. Fixed my moving _deadstate to an _internal_poll method.

2833-------------
2834
Nick Coghlan6e8fef02008-08-18 13:14:22 +00002835- Issue #2235: the C API function PyObject_HashNotImplemented and its
2836 interaction with the tp_hash slot (added in 2.6b2) are now documented
2837
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002838- Issue #643841: The language reference now provides more detailed
2839 coverage of the lookup process for special methods. The disclaimers
2840 regarding lack of coverage of new-style classes have also been
2841 removed, since the coverage is now fairly reasonable.

2850-----------------
2851
Georg Brandl3e483f62008-07-16 22:57:41 +00002852- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2853 its methods now allow for items objects that can be converted to
2854 an integer using operator.index().
2855
Mark Dickinson64b7e502008-07-16 09:40:03 +00002856- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2857 produced a ValueError instead of giving the correct float.
2858
Eric Smitha5fa5a22008-07-16 00:11:49 +00002859- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2860 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2861
Mark Dickinson7103aa42008-07-15 19:08:33 +00002862- Issue #3008: the float type has a new instance method 'float.hex'
2863 and a new class method 'float.fromhex' to convert floating-point
2864 numbers to and from hexadecimal strings, respectively.
2865
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002866- Issue #2235: __hash__ is once again inherited by default. To allow
2867 collections.Hashable to remain meaningful in the presence of the
2868 default hash implementation (object.__hash__), it is now possible
2869 to explicit block inheritance of hash by setting __hash__=None at
2870 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2871 level.
2872
Nick Coghlanb028f502008-07-13 14:52:36 +00002873- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2874 the parent module cannot be found while performing an absolute import.
2875 This means that an incorrectly defined __package__ attribute will
2876 now only prevent relative imports in that module rather than causing
2877 all imports from that module to fail.
2878
Nick Coghlan14ff9942008-07-08 14:21:42 +00002879- Issue #2517: Allow unicode messages in Exceptions again by correctly
2880 bypassing the instance dictionary when looking up __unicode__ on
2881 new-style classes.
2882
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002883- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2884 set to a custom object whose write() method happens to install
2885 another file in sys.stdout.
2886
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002887- Issue #3088: Corrected a race condition in classes derived from
2888 threading.local: the first member set by a thread could be saved in
2889 another thread's dictionary.
2890
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002891- Issue #3004: Minor change to slice.indices(): the start and stop
2892 arguments are now treated identically, making the behaviour easier
2893 to describe and understand. For example, slice(None, -10,
2894 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2895 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2896 10, -1).
2897
Georg Brandl278fc502008-07-19 12:46:12 +00002898- Issue #3219: Calling a function with repeated keyword arguments,
2899 f(a=2, a=23), would not cause a syntax error. This was a regression
2900 from 2.4 caused by the switch to the new compiler.

2910 api functions without holding the GIL, which could lead to a fatal
2911 error when they failed.
2912
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002913- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

3347
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003348- On MacOS X it is now possible to install the framework in 64-bit
3349 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00003350 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003351
3352 This is controlled by the configure argument ``--with-universal-archs``:
3353
3354 - ``--with-universal-archs=all``: install 4-way universal
3355
3356 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3357
3358 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3359
3360 This option should be used in combination with ``--enable-universalsdk=``.
3361

3399 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00003400
Christian Heimese74c8f22008-04-19 02:23:57 +00003401- Added kill, terminate and send_signal(sig) to subprocess.Popen.
3402

3404 the cmath module.
Christian Heimes6f341092008-04-18 23:13:07 +00003405

Georg Brandl3ee81df2008-05-17 18:14:43 +00003412- Issue #1631171: Re-implement the 'warnings' module in C (the
3413 original Python code has been kept as backup). This will allow for
3414 using the 'warning's machinery in such places as the parser where
3415 use of pure Python code is not possible. Both the ``showarning()``
3416 and ``formatwarning()`` gain an optional 'line' argument which is
3417 not called by default for backwards-compatibility reasons. Setting
3418 ``warnings.showwarning()`` to an implementation that lacks support
3419 for the ``line`` argument will raise a DeprecationWarning.

3443
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00003444- The getpass module has been improved on Unix. It now uses /dev/tty
3445 by default and uses stderr instead of stdout. A GetPassWarning is
3446 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00003447

Georg Brandl3ee81df2008-05-17 18:14:43 +00003461- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00003462 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00003482- Issue #2550: The approach used by client/server code for obtaining
3483 ports to listen on in network-oriented tests has been refined in an
3484 effort to facilitate running multiple instances of the entire
3485 regression test suite in parallel without issue.
3486 test_support.bind_port() has been fixed such that it will always
3487 return a unique port -- which wasn't always the case with the
3488 previous implementation, especially if socket options had been set
3489 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3490 new implementation of bind_port() will actually raise an exception
3491 if it is passed an AF_INET/SOCK_STREAM socket with either the
3492 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3493 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3494 the socket it's been passed. This currently only applies to
3495 Windows. This option prevents any other sockets from binding to the
3496 host/port we've bound to, thus removing the possibility of the
3497 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3498 when a second SOCK_STREAM socket binds and accepts to a host/port
3499 that's already been bound by another socket. The optional preferred
3500 port parameter to bind_port() has been removed. Under no
3501 circumstances should tests be hard coding ports!
3502
3503 test_support.find_unused_port() has also been introduced, which will
3504 pass a temporary socket object to bind_port() in order to obtain an
3505 unused port. The temporary socket object is then closed and
3506 deleted, and the port is returned. This method should only be used
3507 for obtaining an unused port in order to pass to an external program
3508 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3509 a parameter to a server-oriented class that doesn't give you direct
3510 access to the underlying socket used.
3511
3512 Finally, test_support.HOST has been introduced, which should be used
3513 for the host argument of any relevant socket calls (i.e. bind and
3514 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003515
3516 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003517 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003518 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3519 test_asynchat and test_socket_ssl.
3520
Georg Brandl3ee81df2008-05-17 18:14:43 +00003521 It is now possible for multiple instances of the regression test
3522 suite to run in parallel without issue.

3788Core and builtins
3789-----------------
3790
Fred Drakea8ee94b2008-03-01 02:45:07 +00003791- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003792 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00003793
Georg Brandlad61bc82008-02-23 15:11:18 +00003794- Issue #2067: file.__exit__() now calls subclasses' close() method.
3795
3796- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003797
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003798- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003799 issue 215555 for a discussion.
3800
Eric Smitha73fbe72008-02-23 03:09:44 +00003801- Added the future_builtins module, which contains hex() and oct().
3802 These are the PEP 3127 version of these functions, designed to be
3803 compatible with the hex() and oct() builtins from Python 3.0. They
3804 differ slightly in their output formats from the existing, unchanged
3805 Python 2.6 builtins. The expected usage of the future_builtins
3806 module is:
3807 from future_builtins import hex, oct
3808
Eric Smith7ef40bf2008-02-20 23:34:22 +00003809- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3810 exponents for exponents with absolute value < 100. Follows C99
3811 standard. This is a change on Windows, which would use 3 digits.
3812 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3813 so that any alterations it does to the resulting string will be
3814 available in stringlib/formatter.h (for float.__format__).
3815
Eric Smith5a3c1352008-02-19 13:21:56 +00003816- Implemented PEP 3101, Advanced String Formatting. This adds a new
3817 builtin format(); a format() method for str and unicode; a
3818 __format__() method to object, str, unicode, int, long, float, and
3819 datetime; the class string.Formatter; and the C API
3820 PyObject_Format().
3821
Georg Brandl3ee81df2008-05-17 18:14:43 +00003822- Fixed several potential crashes, all caused by specially crafted
3823 __del__ methods exploiting objects in temporarily inconsistent
3824 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003825
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003826- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003827 prevent a possible crash: an Abstract Base Class would try to access
3828 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003829
Georg Brandl3ee81df2008-05-17 18:14:43 +00003830- Fixed repr() and str() of complex numbers with infinity or nan as
3831 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003832
Georg Brandl3ee81df2008-05-17 18:14:43 +00003833- Clear all free lists during a gc.collect() of the highest generation
3834 in order to allow pymalloc to free more arenas. Python may give back
3835 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003836
Georg Brandl3ee81df2008-05-17 18:14:43 +00003837- Issue #2045: Fix an infinite recursion triggered when printing a
3838 subclass of collections.defaultdict, if its default_factory is set
3839 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003840
Christian Heimesf75dbef2008-02-08 00:11:31 +00003841- Fixed a minor memory leak in dictobject.c. The content of the free
3842 list was not freed on interpreter shutdown.
3843
Georg Brandl21e99f42010-03-07 15:23:59 +00003844- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003845 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003846
Georg Brandl3ee81df2008-05-17 18:14:43 +00003847- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3848 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003849 to compact the internal free lists of pre-allocted ints and floats.
3850
Georg Brandl3ee81df2008-05-17 18:14:43 +00003851- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3852 calls. Python expected the return type int but the fork familie
3853 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003854
Georg Brandl3ee81df2008-05-17 18:14:43 +00003855- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3856 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003857
Georg Brandl3ee81df2008-05-17 18:14:43 +00003858- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3859 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003860
Georg Brandl3ee81df2008-05-17 18:14:43 +00003861- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3862 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003863
Georg Brandl3ee81df2008-05-17 18:14:43 +00003864- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3865 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003866
Georg Brandl3ee81df2008-05-17 18:14:43 +00003867- Patch #1473257: generator objects gain a gi_code attribute. This is
3868 the same object as the func_code attribute of the function that
3869 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003870
Georg Brandl3ee81df2008-05-17 18:14:43 +00003871- Issue #1920: "while 0" statements were completely removed by the
3872 compiler, even in the presence of an "else" clause, which is
3873 supposed to be run when the condition is false. Now the compiler
3874 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003875
Guido van Rossumeead05f2008-01-24 18:21:02 +00003876- A few crashers fixed: weakref_in_del.py (issue #1377858);
3877 loosing_dict_ref.py (issue #1303614, test67.py);
3878 borrowed_ref_[34].py (not in tracker).
3879
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003880- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003881 suppressed while an extension is loaded by calling SetErrorMode in
3882 dynload_win.c. The error is still reported properly.
3883
Georg Brandl3ee81df2008-05-17 18:14:43 +00003884- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003885 several extension methods and modules do not work without unicode
3886 support.
3887
Georg Brandl26543b12008-01-21 18:36:51 +00003888- Issue #1882: when compiling code from a string, encoding cookies in the
3889 second line of code were not always recognized correctly.
3890
Georg Brandl14404b62008-01-19 19:27:05 +00003891- Issue #1679: "0x" was taken as a valid integer literal.
3892
Georg Brandl6caad7d2008-01-26 14:19:22 +00003893- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003894 added.
3895
Christian Heimesc94e2b52008-01-14 04:13:37 +00003896- sys.float_info / PyFloat_GetInfo: The floating point information
3897 object was converted from a dict to a specialized structseq object.
3898
Georg Brandl3ee81df2008-05-17 18:14:43 +00003899- Patch #1816: Added sys.flags structseq. It exposes the status of
3900 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003901
Georg Brandl3ee81df2008-05-17 18:14:43 +00003902- Objects/structseq.c: Implemented new structseq representation. The
3903 patch makes structseqs (e.g. the return value of os.stat) more
3904 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003905
Georg Brandl3ee81df2008-05-17 18:14:43 +00003906- Patch #1700288: added a type attribute cache that caches method
3907 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003908
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003909- Bug #1776: __import__() no longer accepts filenames on any platform.

3913
Georg Brandl3ee81df2008-05-17 18:14:43 +00003914- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3915 envvar and sys.dont_write_bytecode attribute. All these can be set
3916 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003917
Georg Brandl3ee81df2008-05-17 18:14:43 +00003918- Improve some exception messages when Windows fails to load an
3919 extension module. Now we get for example '%1 is not a valid Win32
3920 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003921
Georg Brandl3ee81df2008-05-17 18:14:43 +00003922- Bug #1481296: Fixed long(float('nan')) != 0L.

3925 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003926
Christian Heimes0a8143f2007-12-18 23:22:54 +00003927- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003928 and INF. float("nan"), float("inf") and float("-inf") now work on
3929 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003930
Georg Brandl3ee81df2008-05-17 18:14:43 +00003931- Compiler now generates simpler and faster code for dictionary
3932 literals. The oparg for BUILD_MAP now indicates an estimated
3933 dictionary size. There is a new opcode, STORE_MAP, for adding
3934 entries to the dictionary.

3966 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003967
Georg Brandl3ee81df2008-05-17 18:14:43 +00003968- Issue #1265: Fix a problem with sys.settrace, if the tracing
3969 function uses a generator expression when at the same time the
3970 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003971
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003972- sets and frozensets now have an isdisjoint() method.

3977
Georg Brandl21e99f42010-03-07 15:23:59 +00003978- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003979 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3980 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003981
Georg Brandl3ee81df2008-05-17 18:14:43 +00003982- Issue #1686386: Tuple's tp_repr did not take into account the
3983 possibility of having a self-referential tuple, which is possible
3984 from C code. Nor did object's tp_str consider that a type's tp_str
3985 could do something that could lead to an inifinite recursion.
3986 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3987 issues.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003989- Issue #1164: It was possible to trigger deadlock when using the
3990 'print' statement to write to a file since the GIL was not released
3991 as needed. Now PyObject_Print() does the right thing along with
3992 various tp_print implementations of the built-in types and those in
3993 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003994
Georg Brandl3ee81df2008-05-17 18:14:43 +00003995- Issue #1147: Exceptions were directly allowing string exceptions in
3996 their throw() method even though string exceptions no longer
3997 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003998
Georg Brandl3ee81df2008-05-17 18:14:43 +00003999- Issue #1096: Prevent a segfault from getting the repr of a very
4000 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004001
Brett Cannon1e534b52007-09-07 04:18:30 +00004002- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004003 PyObject_Call() never calling back out to Python code to trigger
4004 recursion depth updates/checks. Required the creation of a static
4005 RuntimeError instance in case normalizing an exception put the
4006 recursion check value past its limit. Fixes crashers
4007 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004008
Georg Brandl3ee81df2008-05-17 18:14:43 +00004009- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00004022- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004023 __*__ attributes. (Some already existed, e.g., __doc__ and
4024 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004025
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004026- Add -3 option to the interpreter to warn about features that are
4027 deprecated and will be changed/removed in Python 3.0.
4028
Georg Brandl2134e752007-05-21 20:34:16 +00004029- Patch #1686487: you can now pass any mapping after '**' in function
4030 calls.
4031
Collin Winter62903052007-05-18 23:11:24 +00004032- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004033 "except E as target:". This is to provide forwards compatibility
4034 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004035
Brett Cannon229cee22007-05-05 01:34:02 +00004036- Deprecate BaseException.message as per PEP 352.
4037
Georg Brandl3ee81df2008-05-17 18:14:43 +00004038- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004039 inherited from a built-in base.

Vinay Sajip8549ce32007-05-06 17:53:37 +00004041- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004042 setting a plain string, ie don't expand to single letter identifiers.
4043
Raymond Hettinger13936692007-04-11 18:40:58 +00004044- Request #1191699: Slices can now be pickled.
4045
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004046- Request #1193128: str.translate() now allows a None argument for
4047 translations that only remove characters without re-mapping the
4048 remaining characters.
4049
Georg Brandl5cb76c12007-03-21 09:00:39 +00004050- Patch #1682205: a TypeError while unpacking an iterable is no longer
4051 masked by a generic one with the message "unpack non-sequence".
4052
Neal Norwitzaa754b72007-03-21 06:39:48 +00004053- Remove unused file Python/fmod.c.
4054
Guido van Rossum143b5642007-03-23 04:58:42 +00004055- Bug #1683368: The object.__init__() and object.__new__() methods are
4056 now stricter in rejecting excess arguments. The only time when
4057 either allows excess arguments is when it is not overridden and the
4058 other one is. For backwards compatibility, when both are
4059 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004060 warning later). Also, type.__init__() insists on the same signature
4061 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004062
Georg Brandl3ee81df2008-05-17 18:14:43 +00004063- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4064 object to complex using its __complex__() method before falling back
4065 to the __float__() method. Therefore, the functions in the cmath
4066 module now can operate on objects that define a __complex__()
4067 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004068
Georg Brandl3ee81df2008-05-17 18:14:43 +00004069- Patch #1623563: allow __class__ assignment for classes with
4070 __slots__. The old and the new class are still required to have the
4071 same slot names.

4077 ``object.__reduce_ex__()`` is called with an object that is faking
4078 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00004079
Georg Brandl3ee81df2008-05-17 18:14:43 +00004080- Patch #1680015: Don't modify __slots__ tuple if it contains an

4084
Georg Brandl7b9c5552007-03-12 14:30:05 +00004085- Bug #1678647: write a newline after printing an exception in any
4086 case, even when converting the value to a string failed.
4087
Georg Brandl871f1bc2007-03-12 13:17:36 +00004088- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004089 its argument, if it exists. If not, it will work like before. This
4090 allows customizing the output of dir() in the presence of a
4091 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00004092
Collin Winter276887b2007-03-12 16:11:39 +00004093- Patch #922167: Python no longer segfaults when faced with infinitely

4100 parthensized forms. This means complex(repr(x)) now works instead of
4101 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004102
Georg Brandlaa2321b2007-03-07 00:40:28 +00004103- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004104 makes the filenames the warning module prints much more sensible
4105 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004106
Georg Brandl49aafc92007-03-07 00:34:46 +00004107- Variant of patch #697613: don't exit the interpreter on a SystemExit
4108 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00004109 variable is given, but break into the interactive interpreter just
4110 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00004118- Patch #1674228: when assigning a slice (old-style), check for the
4119 sq_ass_slice instead of the sq_slice slot.
4120
Georg Brandl3ee81df2008-05-17 18:14:43 +00004121- When printing an unraisable error, don't print exceptions. before
4122 the name. This duplicates the behavior whening normally printing
4123 exceptions.

4226 .pyc files generated before 2.5c2 will be regenerated.
Neal Norwitzdac090d2006-09-05 03:53:08 +00004227

4732 Python would crash instead of raising an error.

4751 -- the failure just occurred later, with a more cumbersome
4752 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005033- Issue #829951: In the smtplib module, SMTP.starttls() now complies
5034 with RFC 3207 and forgets any knowledge obtained from the server not
5035 obtained from the TLS negotiation itself. Patch contributed by Bill
5036 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00005037
Georg Brandl3ee81df2008-05-17 18:14:43 +00005038- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005039 that the SMTP.starttls() caller no longer needs to call ehlo()
5040 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00005041 does not claim to support starttls. Adds the
5042 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

5123 complex, tuple, list, dict, set, and frozenset. Formerly, it would
5124 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00005141 time so that opening a database previously created with the DB_DUP
5142 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5143 opens. Specifically: dictionary assignment to a DB object will
5144 replace all values for a given key when the database allows
5145 duplicate values. DB users should use DB.put(k, v) when they want
5146 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005147

5153 characters with ASCII value less than 32. Also, it correctly quotes
5154 dots only if they occur on a single line, as opposed to the previous
5155 behavior of quoting dots if they are the second character of any
5156 line.

5479-----
5480
Georg Brandl3ee81df2008-05-17 18:14:43 +00005481- Unified naming convention for free lists and their limits. All free
5482 lists in Object/ are named ``free_list``, the counter ``numfree``
5483 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
5484 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00005485
Georg Brandl3ee81df2008-05-17 18:14:43 +00005486- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5487 to ``PyTuple_SetItem``, it can be used to populate a brand new
5488 frozenset; but it does not steal a reference to the added item.

5493 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
5494 PyLong_FromSsize_t public functions.

5497
5498- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
5499 ``PyFloat_GetInfo()`` to the float API.
5500
Georg Brandl3ee81df2008-05-17 18:14:43 +00005501- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5502 of w# format code incorrectly truncated the length to an int, even
5503 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5504 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005505
Georg Brandl3ee81df2008-05-17 18:14:43 +00005506- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
5507 Py_TYPE and Py_REFCNT.

5523
5524- Fix some leftovers from the conversion from int to Py_ssize_t
5525 (relevant to strings and sequences of more than 2**31 items).
5526
5527- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5528 outside of pystate.c and should not be necessary.
5529
Georg Brandl3ee81df2008-05-17 18:14:43 +00005530- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5531 absolute imports. In earlier versions they might have used relative
5532 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005533
Georg Brandl3ee81df2008-05-17 18:14:43 +00005534- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5535 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005536
Georg Brandl3ee81df2008-05-17 18:14:43 +00005537- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00005544- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
5545 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
5546 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
5547 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00005548

Georg Brandl3ee81df2008-05-17 18:14:43 +00005562- Removed the macfs module. It had been deprecated since Python 2.5.
5563 This lead to the deprecation of macostools.touched() as it relied
5564 solely on macfs and was a no-op under OS X.
