55 a base64 transfer-encoded payload *after* decoding it; it no longer does.

Georg Brandlba83f822010-03-14 09:50:54 +000066- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
67 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
68 argument's __int__ method to convert to an integer before packing. It also
69 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
70 was inconsistent: __int__ was used for some integer codes but not for others,
71 and the set of integer codes for which it was used differed between native
72 packing and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +0000266- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
267 and add the additional members returned in an OSVERSIONINFOEX structure. The
268 new members are service_pack_major, service_pack_minor, suite_mask, and
269 product_type.

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

306 XML processing instructions and comments. These raw characters are allowed
307 by the XML specification, and are necessary when outputting e.g. PHP code in
308 a processing instruction. Patch by Neil Muller.

Antoine Pitroud840e512010-02-04 20:20:18 +0000316- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +0000317 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +0000318 Also, raise ValueError rather than TypeError when an unknown TIPC address
319 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000323- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +0000324 file position when calling `truncate()`. It would previously change the file
325 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000326 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
327
Benjamin Petersone06f7112010-01-28 02:15:02 +0000328- UserDict is now a new-style class.
329
Georg Brandlba83f822010-03-14 09:50:54 +0000330- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
331 class used to represent files stored inside an archive. The new
332 implementation is significantly faster and can be wrapped in a
333 ``io.BufferedReader`` object for more speedups. It also solves an issue
334 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
335 Patch by Nir Aides.
Antoine Pitrou94c33eb2010-01-27 20:59:50 +0000336

343 when the release file is empty.
Benjamin Petersona43f34c2010-01-25 03:31:13 +0000344
Georg Brandlba83f822010-03-14 09:50:54 +0000345- Issue #7748: Since unicode values are supported for some metadata options in
346 Distutils, the DistributionMetadata get_* methods will now return an utf-8
347 encoded string for them. This ensures that the upload and register commands
348 send the correct values to PyPI without any error.

422Core and Builtins
423-----------------
424
Georg Brandlba83f822010-03-14 09:50:54 +0000425- The ``__complex__()`` method is now looked up on the class of instances to
426 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000428- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
429 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
430
Mark Dickinson1b34d252010-01-01 17:27:30 +0000431- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000432 DeprecationWarning when passed a float argument where an integer was expected.
433 These functions and methods now raise TypeError instead. The majority of the
434 effects of this change are in the extension modules, but some core functions
435 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
436 and many unicode/str methods.

447 used to drop the time part of the result.
448
Georg Brandlba83f822010-03-14 09:50:54 +0000449- Issue #1811: Improve accuracy and cross-platform consistency for true division
450 of integers: the result of a/b is now correctly rounded for ints a and b (at
451 least on IEEE 754 platforms), and in particular does not depend on the
452 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +0000453
Georg Brandlba83f822010-03-14 09:50:54 +0000454- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the

460
Georg Brandlba83f822010-03-14 09:50:54 +0000461 These executables now work properly with the arch(1) command: ``arch -ppc
462 python`` will start a universal binary version of python in PPC mode (unlike
463 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +0000464
Georg Brandlba83f822010-03-14 09:50:54 +0000465- Issue #1680159: Unicode coercion during an 'in' operation no longer masks the

603 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000604

606 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000607

Georg Brandlba83f822010-03-14 09:50:54 +0000619- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
620 decimal string that's guaranteed to round back to x under correct rounding
621 (with round-half-to-even rounding mode). Previously it gave a string based on
622 rounding x to 17 decimal digits. repr(x) for a complex number behaves
623 similarly. On platforms where the correctly-rounded strtod and dtoa code is
624 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000625
Georg Brandlba83f822010-03-14 09:50:54 +0000626- Issue #7117: On almost all platforms: float-to-string and string-to-float
627 conversions within Python are now correctly rounded. Places these conversions
628 occur include: str for floats and complex numbers; the float and complex
629 constructors; old-style and new-style numeric formatting; serialization and
630 deserialization of floats and complex numbers using marshal, pickle and json;
631 parsing of float and imaginary literals in Python code; Decimal-to-float
632 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000633
Georg Brandlba83f822010-03-14 09:50:54 +0000634 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
635 providing correctly-rounded strtod and dtoa C functions. This code is
636 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
637 the C compiler. There may be a small number of platforms on which correct
638 operation of this code cannot be guaranteed, so the code is not used: notably,
639 this applies to platforms where the C double format is not IEEE 754 binary64,
640 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
641 and Python's configure script is unable to determine how to change the FPU
642 precision. On these platforms conversions use the platform strtod and dtoa,
643 as before.

Georg Brandlba83f822010-03-14 09:50:54 +0000645- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
646 uses the correctly-rounded string <-> float conversions described above (when
647 available), and so produces correctly rounded results that will display nicely
648 under the float repr. There are two related small changes: (1) round now
649 accepts any class with an ``__index__()`` method for its second argument (but
650 no longer accepts floats for the second argument), and (2) an excessively
651 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
652 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +0000746- Issue #6347: Include inttypes.h as well as stdint.h in pyport.h. This fixes a
747 build failure on HP-UX: int32_t and uint32_t are defined in inttypes.h instead
748 of stdint.h on that platform.

Mark Dickinsonb1d45852009-05-11 15:33:08 +0000794
Georg Brandlba83f822010-03-14 09:50:54 +0000795 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
796 (2) parsing of strings representing infinities and nans was locale aware; and
797 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').
Eric Smitha985a3a2009-05-05 18:26:08 +0000798
Georg Brandlba83f822010-03-14 09:50:54 +0000799- Issue #5920: For ``float.__format__()``, change the behavior with the empty
800 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
801 but with at least one decimal point and with a default precision
802 of 12. Previously, the behavior the same but with a default precision of 6.
803 This more closely matches ``str()``, and reduces surprises when adding
804 alignment flags to the empty presentation type. This also affects the new
805 complex.__format__ in the same way.
806
807- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
808 classtype's, even if it was None. property now inserts the __doc__ into the

1002
Georg Brandlba83f822010-03-14 09:50:54 +00001003- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
1004 file objects with closefd=False. The file descriptor is still kept open but
1005 the file object behaves like a closed file. The ``FileIO`` object also got a

Benjamin Peterson399b1fe2008-10-25 02:53:28 +00001026- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00001029- On windows, ``os.chdir()`` given unicode was not working if
1030 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
1031 this code path is really executed because I cannot move to such directory on
1032 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00001034- Issue #4069: When ``set.remove(element)`` is used with a set element, the
1035 element is temporarily replaced with an equivalent frozenset. But the
1036 eventual KeyError would always report the empty ``frozenset()`` as the missing
1037 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00001057- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
1058 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1059 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1060 of using the replace error handler in PyUnicode_DecodeUTF8().
1061
Walter Dörwald726ba8e2009-05-06 14:32:35 +00001062- Issue #3739: The unicode-internal encoder now reports the number of characters

1064
Georg Brandlba83f822010-03-14 09:50:54 +00001065- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
1066 allocator will be automatically disabled when running under Valgrind. This
1067 gives improved memory leak detection when running under Valgrind, while taking
1068 advantage of pymalloc at other times.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002433- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2434
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002435- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2436 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2437 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2438 ``printf`` function, whereas PyString_FromFormat has an independent
2439 implementation and uses "%zd" on all platforms for size_t values.
2440 This makes a difference on win64, where ``printf`` needs "%Id" to display
2441 64bit values.
2442
Benjamin Peterson97179b02008-09-09 20:55:01 +00002443- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

2447 object; previously an int would be returned for small values. the __long__
2448 method is allowed to return either an int or a long, but the behaviour of
2449 float objects should not change to respect backward compatibility.
2450
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002451- Issue #3751: str.rpartition would perform a left-partition when called with
2452 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +00002457 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002458 was correctly parsed but parsing of subsequent arguments failed.
2459
Vinay Sajip35e3b032008-09-01 14:33:59 +00002460- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002461 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2462 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2463 when given a tuple of classes as second argument, were looking up
2464 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2465 type object.
2466
Neal Norwitz18aa3882008-08-24 05:04:52 +00002467- Fix crashes on memory allocation failure found with failmalloc.
2468
2469- Fix memory leaks found with valgrind and update suppressions file.
2470
2471- Fix compiler warnings in opt mode which would lead to invalid memory reads.

2536 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2537 for catch_warnings() also led to an improvement in the raising of a

2610-----------------
2611
Guido van Rossumf8402962008-08-20 15:01:50 +00002612- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2613 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2614 extensions do not automatically benefit from the class attribute
2615 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2616 to their tp_flags field if they care. This is a backwards
2617 compatibility feature; in 3.0, all types will use the cache by
2618 default.
2619
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002620- Keyword arguments can now follow starred arguments. (``f(a, *args,
2621 keyword=23)`` is now valid syntax.)
2622
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002623- ctypes function pointers that are COM methods have a boolean True
2624 value again.
2625
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002626- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2627 by denying s# to parse objects that have a releasebuffer procedure,
2628 and introducing s*.
2629
Georg Brandl1e13ea92008-08-11 09:07:59 +00002630- Issue #3537: Fix an assertion failure when an empty but presized dict
2631 object was stored in the freelist.

Mark Dickinsonb6467572008-08-04 21:30:09 +00002633- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2634 ValueError consistently across platforms.
2635
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002636- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2637 (64bit Unix, for example), unichr() would truncate its argument and return
2638 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2639
Neal Norwitze7d8be82008-07-31 17:17:14 +00002640- Apply security patches from Apple.
2641
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002642- Issue #2542: Now that issubclass() may call arbitrary code, ensure that

Antoine Pitrou92f82162008-07-25 22:22:08 +00002645- Issue #1819: function calls with several named parameters are now on
2646 average 35% faster (as measured by pybench).
2647
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002648- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2649 the python debugger steps into a class statement: the free variables (local
2650 variables defined in an outer scope) would be deleted from the outer scope.
2651
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002652- Issue #2620: Overflow checking when allocating or reallocating memory
2653 was not always being done properly in some python types and extension
2654 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2655 all been updated to perform better checks and places in the code that
2656 would previously leak memory on the error path when such an allocation
2657 failed have been fixed.

2663
Benjamin Petersone977ad42008-08-20 01:42:01 +00002664- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2665 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2666
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002667- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2668 version reported by these tools does not necessarily follow the python
2669 version numbering scheme, so the module is less strict when parsing it.
2670
Nick Coghlanf70385a2008-08-18 12:42:46 +00002671- Issue #2235: Added Py3k warnings for types which will become unhashable
2672 under the stricter __hash__ inheritance rules in 3.0. Several types
2673 which did not meet the rules for hash invariants and were already
2674 unhashable in 3.0 have now been explicitly flagged as unhashable in
2675 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2676 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2677
Brett Cannon88f801d2008-08-18 00:46:22 +00002678- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2679 imported into the module but exposed as part of the module's API.
2680

2686
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002687- Issue #3575: Incremental decoder's decode function now takes bytearray
2688 by using 's*' instead of 't#'.
2689
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002690- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002691 fails unicode conversion on 2nd parameter. (windows only)
2692
Facundo Batista94f243a2008-08-17 03:38:39 +00002693- Issue 2464. urllib2 now supports a malformation in the URL received
2694 in a redirect.

Facundo Batistaeb90b782008-08-16 14:44:07 +00002699- Issue #2776: fixed small issue when handling an URL with double slash
2700 after a 302 response in the case of not going through a proxy.
2701
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002702- Issue #2676: in the email package, content-type parsing was hanging on
2703 pathological input because of quadratic or exponential behaviour of a
2704 regular expression.
2705
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002706- Issue #3476: binary buffered reading through the new "io" library is now
2707 thread-safe.
2708
Brett Cannonbf3157b2008-08-14 05:00:03 +00002709- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2710 since mimetools itself is deprecated. Because modules are cached, all
2711 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2712
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002713- Issue #3134: shutil referenced undefined WindowsError symbol.

Robert Schuppenies14646332008-08-10 11:01:53 +00002715- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2716 menu entries were not deleted.
2717
Brett Cannon83e81842008-08-09 23:30:55 +00002718- Copied the implementation of reduce() to _functools.reduce() to have a
2719 version that did not raise a DeprecationWarning under -3.
2720
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002721- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2722 a MemoryError rather than silently stop the iteration.
2723
Guido van Rossum59ce9012008-08-09 14:55:34 +00002724- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2725 to _sre.compile() will now be rejected. This should not affect anybody
2726 since the re.compile() function never generates invalid re-bytecode.
2727
Skip Montanaroa032bf42008-08-08 22:52:51 +00002728- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2729 upon first access it can be automatically initialized from the csv file if
2730 it wasn't initialized during instantiation.
2731
Brett Cannon3aa2a492008-08-06 22:28:09 +00002732- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2733 the reload() built-in has been removed.
2734
Brett Cannon7e30b672008-08-04 21:52:25 +00002735- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002736 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

2744 raised an AttributeError.
2745
Benjamin Peterson01a24322008-07-28 23:35:27 +00002746- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002747 asking for a specific length. This problem only affected files opened
2748 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002749
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00002750- Issue #3449: Update decimal module to use most recent specification
2751 (v. 1.68) and tests (v. 2.58) from IBM.

2772
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002773- Issue #3394: zipfile.writestr sets external attributes when passed a
2774 file name rather than a ZipInfo instance, so files are extracted with
2775 mode 0600 rather than 000 under Unix.
2776
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002777- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2778 argument in python 2.5, this broke code that subclassed Popen to include its
2779 own poll method. Fixed my moving _deadstate to an _internal_poll method.

2787-------------
2788
Nick Coghlan6e8fef02008-08-18 13:14:22 +00002789- Issue #2235: the C API function PyObject_HashNotImplemented and its
2790 interaction with the tp_hash slot (added in 2.6b2) are now documented
2791
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002792- Issue #643841: The language reference now provides more detailed
2793 coverage of the lookup process for special methods. The disclaimers
2794 regarding lack of coverage of new-style classes have also been
2795 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00002798What's New in Python 2.6 beta 2?
2799================================
2800
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002801*Release date: 17-Jul-2008*
2802
Raymond Hettingere3ae6552008-06-20 04:18:15 +00002803Core and Builtins
2804-----------------
2805
Georg Brandl3e483f62008-07-16 22:57:41 +00002806- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2807 its methods now allow for items objects that can be converted to
2808 an integer using operator.index().
2809
Mark Dickinson64b7e502008-07-16 09:40:03 +00002810- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2811 produced a ValueError instead of giving the correct float.
2812
Eric Smitha5fa5a22008-07-16 00:11:49 +00002813- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2814 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2815
Mark Dickinson7103aa42008-07-15 19:08:33 +00002816- Issue #3008: the float type has a new instance method 'float.hex'
2817 and a new class method 'float.fromhex' to convert floating-point
2818 numbers to and from hexadecimal strings, respectively.
2819
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002820- Issue #2235: __hash__ is once again inherited by default. To allow
2821 collections.Hashable to remain meaningful in the presence of the
2822 default hash implementation (object.__hash__), it is now possible
2823 to explicit block inheritance of hash by setting __hash__=None at
2824 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2825 level.
2826
Nick Coghlanb028f502008-07-13 14:52:36 +00002827- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2828 the parent module cannot be found while performing an absolute import.
2829 This means that an incorrectly defined __package__ attribute will
2830 now only prevent relative imports in that module rather than causing
2831 all imports from that module to fail.
2832
Nick Coghlan14ff9942008-07-08 14:21:42 +00002833- Issue #2517: Allow unicode messages in Exceptions again by correctly
2834 bypassing the instance dictionary when looking up __unicode__ on
2835 new-style classes.
2836
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002837- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2838 set to a custom object whose write() method happens to install
2839 another file in sys.stdout.
2840
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002841- Issue #3088: Corrected a race condition in classes derived from
2842 threading.local: the first member set by a thread could be saved in
2843 another thread's dictionary.
2844
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002845- Issue #3004: Minor change to slice.indices(): the start and stop
2846 arguments are now treated identically, making the behaviour easier
2847 to describe and understand. For example, slice(None, -10,
2848 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2849 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2850 10, -1).
2851
Georg Brandl278fc502008-07-19 12:46:12 +00002852- Issue #3219: Calling a function with repeated keyword arguments,
2853 f(a=2, a=23), would not cause a syntax error. This was a regression
2854 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002855
Georg Brandl278fc502008-07-19 12:46:12 +00002856- Issue #2862: Make int and float freelist management consistent with
2857 other freelists. Changes their CompactFreeList apis into
2858 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00002859

2861-------
2862
Thomas Heller57adf222008-08-14 19:10:48 +00002863- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2864 api functions without holding the GIL, which could lead to a fatal
2865 error when they failed.
2866
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002867- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

2874
Jesse Noller13e9d582008-07-16 14:32:36 +00002875- Issue #3125: Remove copy_reg in multiprocessing and replace it with
2876 ForkingPickler.register() to resolve conflict with ctypes.
2877
Vinay Sajip51e65192008-07-18 09:01:10 +00002878- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00002879
Thomas Heller880f5292008-07-15 19:39:38 +00002880- Issue #3313: Fixed a crash when a failed dlopen() call does not set
2881 a valid dlerror() message.
2882
Thomas Heller2bad6572008-07-15 17:19:50 +00002883- Issue #3258: Fixed a crash when a ctypes POINTER type to an
2884 incomplete structure was created.
2885
Brett Cannon3d0b9f02008-07-13 01:15:07 +00002886- Issue #3339: dummy_thread.acquire() should not return None.
2887
Raymond Hettingerb01713e2008-07-10 14:34:57 +00002888- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
2889
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002890- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00002891
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002892- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2893 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002894 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002895 content-length. The problem had been corrected in the 2.4 branch, but never
2896 merged into trunk.
2897
Georg Brandle78fbcc2008-07-05 10:13:36 +00002898- Issue #2663: add filtering capability to shutil.copytree().

2904- Issue #1746: Correct handling of zipfile archive comments (previously
2905 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00002906 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00002907
Vinay Sajip51e65192008-07-18 09:01:10 +00002908- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002909 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00002910
Nick Coghlanc060b0e2008-07-02 13:09:19 +00002911- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
2912 handling is now the same as that of other special attributes like __name__).
2913
Brett Cannon8bb8fa52008-07-02 01:57:08 +00002914- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
2915 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl5cc774e2008-06-11 20:28:06 +00003304 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003305
3306 This is controlled by the configure argument ``--with-universal-archs``:
3307
3308 - ``--with-universal-archs=all``: install 4-way universal
3309
3310 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3311
3312 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3313
3314 This option should be used in combination with ``--enable-universalsdk=``.
3315
3316 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00003366- Issue #1631171: Re-implement the 'warnings' module in C (the
3367 original Python code has been kept as backup). This will allow for
3368 using the 'warning's machinery in such places as the parser where
3369 use of pure Python code is not possible. Both the ``showarning()``
3370 and ``formatwarning()`` gain an optional 'line' argument which is
3371 not called by default for backwards-compatibility reasons. Setting
3372 ``warnings.showwarning()`` to an implementation that lacks support
3373 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003436- Issue #2550: The approach used by client/server code for obtaining
3437 ports to listen on in network-oriented tests has been refined in an
3438 effort to facilitate running multiple instances of the entire
3439 regression test suite in parallel without issue.
3440 test_support.bind_port() has been fixed such that it will always
3441 return a unique port -- which wasn't always the case with the
3442 previous implementation, especially if socket options had been set
3443 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3444 new implementation of bind_port() will actually raise an exception
3445 if it is passed an AF_INET/SOCK_STREAM socket with either the
3446 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3447 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3448 the socket it's been passed. This currently only applies to
3449 Windows. This option prevents any other sockets from binding to the
3450 host/port we've bound to, thus removing the possibility of the
3451 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3452 when a second SOCK_STREAM socket binds and accepts to a host/port
3453 that's already been bound by another socket. The optional preferred
3454 port parameter to bind_port() has been removed. Under no
3455 circumstances should tests be hard coding ports!
3456
3457 test_support.find_unused_port() has also been introduced, which will
3458 pass a temporary socket object to bind_port() in order to obtain an
3459 unused port. The temporary socket object is then closed and
3460 deleted, and the port is returned. This method should only be used
3461 for obtaining an unused port in order to pass to an external program
3462 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3463 a parameter to a server-oriented class that doesn't give you direct
3464 access to the underlying socket used.
3465
3466 Finally, test_support.HOST has been introduced, which should be used
3467 for the host argument of any relevant socket calls (i.e. bind and
3468 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003469
3470 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003471 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,

3473 test_asynchat and test_socket_ssl.
3474
Georg Brandl3ee81df2008-05-17 18:14:43 +00003475 It is now possible for multiple instances of the regression test

Fred Drakea8ee94b2008-03-01 02:45:07 +00003745- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003746 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00003747
Georg Brandlad61bc82008-02-23 15:11:18 +00003748- Issue #2067: file.__exit__() now calls subclasses' close() method.
3749
3750- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003751
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003752- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003753 issue 215555 for a discussion.
3754
Eric Smitha73fbe72008-02-23 03:09:44 +00003755- Added the future_builtins module, which contains hex() and oct().
3756 These are the PEP 3127 version of these functions, designed to be
3757 compatible with the hex() and oct() builtins from Python 3.0. They
3758 differ slightly in their output formats from the existing, unchanged
3759 Python 2.6 builtins. The expected usage of the future_builtins
3760 module is:
3761 from future_builtins import hex, oct
3762
Eric Smith7ef40bf2008-02-20 23:34:22 +00003763- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3764 exponents for exponents with absolute value < 100. Follows C99
3765 standard. This is a change on Windows, which would use 3 digits.
3766 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3767 so that any alterations it does to the resulting string will be
3768 available in stringlib/formatter.h (for float.__format__).
3769
Eric Smith5a3c1352008-02-19 13:21:56 +00003770- Implemented PEP 3101, Advanced String Formatting. This adds a new
3771 builtin format(); a format() method for str and unicode; a
3772 __format__() method to object, str, unicode, int, long, float, and
3773 datetime; the class string.Formatter; and the C API
3774 PyObject_Format().
3775
Georg Brandl3ee81df2008-05-17 18:14:43 +00003776- Fixed several potential crashes, all caused by specially crafted
3777 __del__ methods exploiting objects in temporarily inconsistent
3778 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003779
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003780- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003781 prevent a possible crash: an Abstract Base Class would try to access
3782 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003783
Georg Brandl3ee81df2008-05-17 18:14:43 +00003784- Fixed repr() and str() of complex numbers with infinity or nan as
3785 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003786
Georg Brandl3ee81df2008-05-17 18:14:43 +00003787- Clear all free lists during a gc.collect() of the highest generation
3788 in order to allow pymalloc to free more arenas. Python may give back
3789 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003790
Georg Brandl3ee81df2008-05-17 18:14:43 +00003791- Issue #2045: Fix an infinite recursion triggered when printing a
3792 subclass of collections.defaultdict, if its default_factory is set
3793 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003794
Christian Heimesf75dbef2008-02-08 00:11:31 +00003795- Fixed a minor memory leak in dictobject.c. The content of the free
3796 list was not freed on interpreter shutdown.
3797
Georg Brandl21e99f42010-03-07 15:23:59 +00003798- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003799 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003800
Georg Brandl3ee81df2008-05-17 18:14:43 +00003801- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3802 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003803 to compact the internal free lists of pre-allocted ints and floats.
3804
Georg Brandl3ee81df2008-05-17 18:14:43 +00003805- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3806 calls. Python expected the return type int but the fork familie
3807 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003808
Georg Brandl3ee81df2008-05-17 18:14:43 +00003809- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3810 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003811
Georg Brandl3ee81df2008-05-17 18:14:43 +00003812- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3813 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003814
Georg Brandl3ee81df2008-05-17 18:14:43 +00003815- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3816 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003817
Georg Brandl3ee81df2008-05-17 18:14:43 +00003818- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3819 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003820
Georg Brandl3ee81df2008-05-17 18:14:43 +00003821- Patch #1473257: generator objects gain a gi_code attribute. This is
3822 the same object as the func_code attribute of the function that
3823 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003824
Georg Brandl3ee81df2008-05-17 18:14:43 +00003825- Issue #1920: "while 0" statements were completely removed by the
3826 compiler, even in the presence of an "else" clause, which is
3827 supposed to be run when the condition is false. Now the compiler
3828 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003829
Guido van Rossumeead05f2008-01-24 18:21:02 +00003830- A few crashers fixed: weakref_in_del.py (issue #1377858);
3831 loosing_dict_ref.py (issue #1303614, test67.py);
3832 borrowed_ref_[34].py (not in tracker).
3833
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003834- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003835 suppressed while an extension is loaded by calling SetErrorMode in
3836 dynload_win.c. The error is still reported properly.
3837
Georg Brandl3ee81df2008-05-17 18:14:43 +00003838- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003839 several extension methods and modules do not work without unicode
3840 support.
3841
Georg Brandl26543b12008-01-21 18:36:51 +00003842- Issue #1882: when compiling code from a string, encoding cookies in the
3843 second line of code were not always recognized correctly.
3844
Georg Brandl14404b62008-01-19 19:27:05 +00003845- Issue #1679: "0x" was taken as a valid integer literal.
3846
Georg Brandl6caad7d2008-01-26 14:19:22 +00003847- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003848 added.
3849
Christian Heimesc94e2b52008-01-14 04:13:37 +00003850- sys.float_info / PyFloat_GetInfo: The floating point information
3851 object was converted from a dict to a specialized structseq object.
3852
Georg Brandl3ee81df2008-05-17 18:14:43 +00003853- Patch #1816: Added sys.flags structseq. It exposes the status of
3854 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003855
Georg Brandl3ee81df2008-05-17 18:14:43 +00003856- Objects/structseq.c: Implemented new structseq representation. The
3857 patch makes structseqs (e.g. the return value of os.stat) more
3858 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003859
Georg Brandl3ee81df2008-05-17 18:14:43 +00003860- Patch #1700288: added a type attribute cache that caches method
3861 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003862
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003863- Bug #1776: __import__() no longer accepts filenames on any platform.
3864 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003865
Georg Brandlaed6c662008-01-07 17:25:53 +00003866- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3867
Georg Brandl3ee81df2008-05-17 18:14:43 +00003868- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3869 envvar and sys.dont_write_bytecode attribute. All these can be set
3870 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003871
Georg Brandl3ee81df2008-05-17 18:14:43 +00003872- Improve some exception messages when Windows fails to load an
3873 extension module. Now we get for example '%1 is not a valid Win32
3874 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003875
Georg Brandl3ee81df2008-05-17 18:14:43 +00003876- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003878- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3879 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003880
Christian Heimes0a8143f2007-12-18 23:22:54 +00003881- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003882 and INF. float("nan"), float("inf") and float("-inf") now work on
3883 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003884
Georg Brandl3ee81df2008-05-17 18:14:43 +00003885- Compiler now generates simpler and faster code for dictionary
3886 literals. The oparg for BUILD_MAP now indicates an estimated
3887 dictionary size. There is a new opcode, STORE_MAP, for adding
3888 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00003889
Georg Brandl3ee81df2008-05-17 18:14:43 +00003890- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003895- Issue #1538: Avoid copying string in split/rsplit if the split char
3896 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00003897
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00003898- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00003899 SystemError.
3900
Nick Coghlanef01d822007-12-03 12:55:17 +00003901- PEP 366: Allow explicit relative imports when executing modules
3902 inside packages with the -m switch via a new module level
3903 __package__ attribute.
3904
Georg Brandl3ee81df2008-05-17 18:14:43 +00003905- Issue #1402: Fix a crash on exit, when another thread is still
3906 running, and if the deallocation of its frames somehow calls the
3907 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00003908

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00003912 attribute of an empty cell object.
3913
Georg Brandl3ee81df2008-05-17 18:14:43 +00003914- Issue #1460: The utf-7 incremental decoder did not accept truncated
3915 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00003916
Georg Brandl3ee81df2008-05-17 18:14:43 +00003917- Patch #1739468: Directories and zipfiles containing a __main__.py
3918 file can now be directly executed by passing their name to the
3919 interpreter. The directory/zipfile is automatically inserted as the
3920 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003921
Georg Brandl3ee81df2008-05-17 18:14:43 +00003922- Issue #1265: Fix a problem with sys.settrace, if the tracing
3923 function uses a generator expression when at the same time the
3924 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003925
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003926- sets and frozensets now have an isdisjoint() method.
3927
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003928- optimize the performance of builtin.sum().
3929
Neal Norwitz44f326e2007-10-05 05:29:17 +00003930- Fix warnings found by the new version of the Coverity checker.
3931
Georg Brandl21e99f42010-03-07 15:23:59 +00003932- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003933 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3934 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003935
Georg Brandl3ee81df2008-05-17 18:14:43 +00003936- Issue #1686386: Tuple's tp_repr did not take into account the
3937 possibility of having a self-referential tuple, which is possible
3938 from C code. Nor did object's tp_str consider that a type's tp_str
3939 could do something that could lead to an inifinite recursion.
3940 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3941 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003942
Georg Brandl3ee81df2008-05-17 18:14:43 +00003943- Issue #1164: It was possible to trigger deadlock when using the
3944 'print' statement to write to a file since the GIL was not released
3945 as needed. Now PyObject_Print() does the right thing along with
3946 various tp_print implementations of the built-in types and those in
3947 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003948
Georg Brandl3ee81df2008-05-17 18:14:43 +00003949- Issue #1147: Exceptions were directly allowing string exceptions in
3950 their throw() method even though string exceptions no longer
3951 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003952
Georg Brandl3ee81df2008-05-17 18:14:43 +00003953- Issue #1096: Prevent a segfault from getting the repr of a very
3954 deeply nested list by using the recursion counter.

Brett Cannon1e534b52007-09-07 04:18:30 +00003956- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003957 PyObject_Call() never calling back out to Python code to trigger
3958 recursion depth updates/checks. Required the creation of a static
3959 RuntimeError instance in case normalizing an exception put the
3960 recursion check value past its limit. Fixes crashers
3961 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003962
Georg Brandl3ee81df2008-05-17 18:14:43 +00003963- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00003976- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003977 __*__ attributes. (Some already existed, e.g., __doc__ and
3978 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003979
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003980- Add -3 option to the interpreter to warn about features that are
3981 deprecated and will be changed/removed in Python 3.0.
3982

Collin Winter62903052007-05-18 23:11:24 +00003986- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003987 "except E as target:". This is to provide forwards compatibility
3988 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003989
Brett Cannon229cee22007-05-05 01:34:02 +00003990- Deprecate BaseException.message as per PEP 352.
3991
Georg Brandl3ee81df2008-05-17 18:14:43 +00003992- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00003993 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00003994
Vinay Sajip8549ce32007-05-06 17:53:37 +00003995- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003996 setting a plain string, ie don't expand to single letter identifiers.
3997
Raymond Hettinger13936692007-04-11 18:40:58 +00003998- Request #1191699: Slices can now be pickled.

Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004000- Request #1193128: str.translate() now allows a None argument for
4001 translations that only remove characters without re-mapping the
4002 remaining characters.
4003
Georg Brandl5cb76c12007-03-21 09:00:39 +00004004- Patch #1682205: a TypeError while unpacking an iterable is no longer
4005 masked by a generic one with the message "unpack non-sequence".

4008
Guido van Rossum143b5642007-03-23 04:58:42 +00004009- Bug #1683368: The object.__init__() and object.__new__() methods are
4010 now stricter in rejecting excess arguments. The only time when
4011 either allows excess arguments is when it is not overridden and the
4012 other one is. For backwards compatibility, when both are
4013 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004014 warning later). Also, type.__init__() insists on the same signature
4015 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004016
Georg Brandl3ee81df2008-05-17 18:14:43 +00004017- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4018 object to complex using its __complex__() method before falling back
4019 to the __float__() method. Therefore, the functions in the cmath
4020 module now can operate on objects that define a __complex__()
4021 method.

4025 same slot names.

4038
Georg Brandl7b9c5552007-03-12 14:30:05 +00004039- Bug #1678647: write a newline after printing an exception in any
4040 case, even when converting the value to a string failed.
4041
Georg Brandl871f1bc2007-03-12 13:17:36 +00004042- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004043 its argument, if it exists. If not, it will work like before. This
4044 allows customizing the output of dir() in the presence of a
4045 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00004046
Collin Winter276887b2007-03-12 16:11:39 +00004047- Patch #922167: Python no longer segfaults when faced with infinitely
4048 self-recursive reload() calls (as reported by bug #742342).

4054 parthensized forms. This means complex(repr(x)) now works instead of
4055 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004056
Georg Brandlaa2321b2007-03-07 00:40:28 +00004057- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004058 makes the filenames the warning module prints much more sensible
4059 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004060

Georg Brandl0fca97a2007-03-05 22:28:08 +00004072- Patch #1674228: when assigning a slice (old-style), check for the
4073 sq_ass_slice instead of the sq_slice slot.
4074
Georg Brandl3ee81df2008-05-17 18:14:43 +00004075- When printing an unraisable error, don't print exceptions. before
4076 the name. This duplicates the behavior whening normally printing
4077 exceptions.

4086 created a weakref on itself during a __del__ call for new-style
4087 classes (classic classes still have the bug).

Georg Brandl2c1375c2006-10-12 11:27:59 +00004127- Bug #1545497: when given an explicit base, int() did ignore NULs
4128 embedded in the string to convert.
4129
Georg Brandl846f73a2006-10-08 07:11:54 +00004130- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00004178 generator expressions (x for x, in ... ) works again. Fixing this
4179 problem required changing the .pyc magic number. This means that
4180 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004987- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4988 with RFC 3207 and forgets any knowledge obtained from the server not
4989 obtained from the TLS negotiation itself. Patch contributed by Bill
4990 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004991
Georg Brandl3ee81df2008-05-17 18:14:43 +00004992- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004993 that the SMTP.starttls() caller no longer needs to call ehlo()
4994 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004995 does not claim to support starttls. Adds the
4996 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

5077 complex, tuple, list, dict, set, and frozenset. Formerly, it would
5078 silently miscode subclasses of those types. Now, it raises a
5079 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00005080

Georg Brandl3ee81df2008-05-17 18:14:43 +00005095 time so that opening a database previously created with the DB_DUP
5096 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5097 opens. Specifically: dictionary assignment to a DB object will
5098 replace all values for a given key when the database allows
5099 duplicate values. DB users should use DB.put(k, v) when they want
5100 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005101

5107 characters with ASCII value less than 32. Also, it correctly quotes
5108 dots only if they occur on a single line, as opposed to the previous
5109 behavior of quoting dots if they are the second character of any
5110 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00005111

5448 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005449
5450- Patch #1720595: add T_BOOL to the range of structmember types.
5451
5452- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
5453 ``PyFloat_GetInfo()`` to the float API.
5454
Georg Brandl3ee81df2008-05-17 18:14:43 +00005455- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5456 of w# format code incorrectly truncated the length to an int, even
5457 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5458 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005459
Georg Brandl3ee81df2008-05-17 18:14:43 +00005460- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
5461 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005463- PEP 3123: Provide forward compatibility with Python 3.0, while
5464 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
5465 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005466
Georg Brandl3ee81df2008-05-17 18:14:43 +00005467- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
5468 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005469
5470- Patch #1733960: Allow T_LONGLONG to accept ints.
5471
5472- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
5473
Christian Heimes000a0742008-01-03 22:16:32 +00005474- Added a new API function ``PyImport_ImportModuleNoBlock``.

Georg Brandl6caad7d2008-01-26 14:19:22 +00005476- Bug #1637022: Prefix AST symbols with _Py_.
5477
5478- Fix some leftovers from the conversion from int to Py_ssize_t
5479 (relevant to strings and sequences of more than 2**31 items).
5480
5481- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5482 outside of pystate.c and should not be necessary.
5483
Georg Brandl3ee81df2008-05-17 18:14:43 +00005484- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5485 absolute imports. In earlier versions they might have used relative
5486 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005487
Georg Brandl3ee81df2008-05-17 18:14:43 +00005488- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5489 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005490
Georg Brandl3ee81df2008-05-17 18:14:43 +00005491- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
5492 macro so it can be used as an expression.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005498- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
5499 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
5500 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
5501 builds.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005516- Removed the macfs module. It had been deprecated since Python 2.5.
5517 This lead to the deprecation of macostools.touched() as it relied
5518 solely on macfs and was a no-op under OS X.
