147 some values large enough to cause overflow, and (4) a number of
148 flaws that could lead to incorrectly rounded results.

185 file position when calling `truncate()`. It would previously change the
186 file position to the given argument, which goes against the tradition of
187 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

207 encoded string for them. This ensure that the upload and register commands
208 send the right values to PyPI without any error.
209
R. David Murrayed44dfa2010-01-16 05:15:17 +0000210- Issue #1670765: Prevent email.generator.Generator from re-wrapping

296 expected. These functions and methods now raise TypeError instead.
297 The majority of the effects of this change are in the extension

299 the 'chr', 'range' and 'xrange' builtins, and many unicode/str
300 methods.

312 used to drop the time part of the result.
313
Mark Dickinson46572832009-12-27 14:55:57 +0000314- Issue #1811: improve accuracy and cross-platform consistency for

484
Mark Dickinsonb678de82009-11-19 18:41:49 +0000485- Issue #7117: repr(x) for a float x returns a result based on the
486 shortest decimal string that's guaranteed to round back to x under
487 correct rounding (with round-half-to-even rounding mode).
488 Previously it gave a string based on rounding x to 17 decimal digits.
489 repr(x) for a complex number behaves similarly. On platforms where
490 the correctly-rounded strtod and dtoa code is not supported (see below),
491 repr is unchanged.
492
493- Issue #7117: On almost all platforms: float-to-string and
494 string-to-float conversions within Python are now correctly rounded.
495 Places these conversions occur include: str for floats and complex
496 numbers; the float and complex constructors; old-style and new-style
497 numeric formatting; serialization and deserialization of floats and
498 complex numbers using marshal, pickle and json; parsing of float and
499 imaginary literals in Python code; Decimal-to-float conversion.
500
501 The conversions use a Python-adapted version of David Gay's
502 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
503 functions. This code is supported on Windows, and on Unix-like
504 platforms using gcc, icc or suncc as the C compiler. There may be a
505 small number of platforms on which correct operation of this code
506 cannot be guaranteed, so the code is not used: notably, this applies
507 to platforms where the C double format is not IEEE 754 binary64, and
508 to platforms on x86 hardware where the x87 FPU is set to 64-bit
509 precision and Python's configure script is unable to determine how
510 to change the FPU precision. On these platforms conversions use the
511 platform strtod and dtoa, as before.
512
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000513- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000514 now uses the correctly-rounded string <-> float conversions
515 described above (when available), and so produces correctly rounded
516 results that will display nicely under the float repr. There are
517 two related small changes: (1) round now accepts any class with an
518 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000519 floats for the second argument), and (2) an excessively large second
520 integer argument (e.g., round(1.234, 10**100)) no longer raises an
521 exception.

614 functions and methods.
615
Mark Dickinson2f865b92009-06-30 15:32:30 +0000616- Issue #6347: Include inttypes.h as well as stdint.h in pyport.h.
617 This fixes a build failure on HP-UX: int32_t and uint32_t are
618 defined in inttypes.h instead of stdint.h on that platform.

628 because it wasn't recognized as a sequence).
629
Benjamin Peterson08a0bbc2009-06-16 00:29:31 +0000630- Issue #6289: Encoding errors from compile() were being masked.
631
Benjamin Petersona72be3b2009-06-13 20:23:33 +0000632- When no module is given in a relative import, the module field of the
633 ImportFrom AST node is now None instead of an empty string.
634
Benjamin Peterson565e1b62009-06-13 03:46:30 +0000635- Assignment to None using import statements now raises a SyntaxError.
636
Amaury Forgeot d'Arcb02ceda2009-06-01 20:53:18 +0000637- Issue #4547: When debugging a very large function, it was not always
638 possible to update the lineno attribute of the current frame.
639
Antoine Pitrou46dbe272009-05-30 21:27:00 +0000640- Issue #5330: C functions called with keyword arguments were not reported by
Benjamin Peterson95e5ebe2009-07-12 23:56:18 +0000641 the various profiling modules (profile, cProfile). Patch by Hagen Fürstenau.
Antoine Pitrou46dbe272009-05-30 21:27:00 +0000642
Raymond Hettinger578a2282009-05-29 04:58:52 +0000643- Issue #5982: staticmethod and classmethod now expose the wrapped
644 function with __func__.
645
Raymond Hettinger822b87f2009-05-29 01:46:48 +0000646- Added support for multiple context managers in the same with-statement.
647 Deprecated contextlib.nested() which is no longer needed.

Benjamin Peterson1880d8b2009-05-25 13:13:44 +0000649- Issue #6101: A new opcode, SETUP_WITH, has been added to speed up the with
650 statement and correctly lookup the __enter__ and __exit__ special methods.
651
Mark Dickinsona4e0efa2009-05-20 18:43:07 +0000652- Issue #5829: complex("1e500") no longer raises OverflowError. This
653 makes it consistent with float("1e500") and interpretation of real
654 and imaginary literals.
655
Hirokazu Yamamotoa4f90182009-05-17 02:58:36 +0000656- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.
657
Benjamin Peterson0c3b4c62009-05-16 23:34:19 +0000658- __instancecheck__ and __subclasscheck__ are now completely ignored on classic
659 classes and instances.
Benjamin Petersoneb9fb2c2009-05-16 22:46:11 +0000660
R. David Murray525cffc2009-05-13 13:07:14 +0000661- Issue #5994: the marshal module now has docstrings.
662
Mark Dickinsonb1d45852009-05-11 15:33:08 +0000663- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
664 (1) inf and nan strings with trailing whitespace were incorrectly
665 rejected; (2) parsing of strings representing infinities and nans
666 was locale aware; and (3) the interpretation of fromhex('-nan')
667 didn't match that of float('-nan').
668
Eric Smitha985a3a2009-05-05 18:26:08 +0000669- Issue #5920: For float.__format__, change the behavior with the
670 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
671 to be like 'g' but with at least one decimal point and with a
672 default precision of 12. Previously, the behavior the same but with
673 a default precision of 6. This more closely matches str(), and
674 reduces surprises when adding alignment flags to the empty
675 presentation type. This also affects the new complex.__format__ in
676 the same way.
677
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000678- Issue #5890: in subclasses of 'property' the __doc__ attribute was
679 shadowed by classtype's, even if it was None. property now
680 inserts the __doc__ into the subclass instance __dict__.
681
Antoine Pitrou653dece2009-05-04 18:32:32 +0000682- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal

696
Eric Smith068f0652009-04-25 21:40:15 +0000697- Issue #5835: Deprecate PyOS_ascii_formatd and replace it with
698 _PyOS_double_to_string or PyOS_double_to_string.
699
Benjamin Peterson5083dc52009-04-25 00:41:22 +0000700- Issue #5283: Setting __class__ in __del__ caused a segfault.
701
Mark Dickinson95bc9802009-04-24 12:46:53 +0000702- Issue #5816: complex(repr(z)) now recovers z exactly, even when
703 z involves nans, infs or negative zeros.
704
Eric Smithaca19e62009-04-22 13:29:05 +0000705- Implement PEP 378, Format Specifier for Thousands Separator, for
706 floats, ints, and longs.
707
708- Issue #5515: 'n' formatting for ints, longs, and floats handles
709 leading zero formatting poorly.
710
711- Issue #5772: For float.__format__, don't add a trailing ".0" if
712 we're using no type code and we have an exponent.
713
Mark Dickinson6736cf82009-04-20 21:13:33 +0000714- Issue #3166: Make long -> float (and int -> float) conversions
715 correctly rounded.

718 some builtin types.
719
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000720- Issue #1869: fix a couple of minor round() issues. round(5e15+1)
Eric Smith9139cc62009-04-30 00:58:58 +0000721 was giving 5e15+2; round(-0.0) was losing the sign of the zero.
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000722
Benjamin Peterson99d36f12009-04-15 21:26:36 +0000723- Issue #5759: float() didn't call __float__ on str subclasses.
724
Georg Brandl3c4a5462009-04-12 12:08:12 +0000725- Issue #5704: the "-3" command-line option now implies "-t".
726
R. David Murray0374a822009-04-09 21:54:50 +0000727- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
728 its clarity and its speed.
729

738 the end sys.path, for compatibility with the system install of Python.
739
Antoine Pitrouf8387af2009-03-23 18:41:45 +0000740- Issue #4688: Add a heuristic so that tuples and dicts containing only
741 untrackable objects are not tracked by the garbage collector. This can
742 reduce the size of collections and therefore the garbage collection overhead
743 on long-running programs, depending on their particular use of datatypes.
744
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000745- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
746 improve its performance. Long divisions and remainder operations
747 are now between 50% and 150% faster.
748
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000749- Issue #4258: Make it possible to use base 2**30 instead of base
750 2**15 for the internal representation of integers, for performance
751 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
752 --enable-big-digits option to configure, which overrides the
753 default. Add sys.long_info structseq to provide information about
754 the internal format.
755
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000756- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
757 result traceback.__members__ no longer exists.)
758
Mark Dickinson6b265f12009-03-18 16:07:26 +0000759- Issue #4474: PyUnicode_FromWideChar now converts characters outside
760 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
761 and sizeof(Py_UNICODE) == 2.
762
Eric Smith6f42edb2009-03-14 11:57:26 +0000763- Issue #5237: Allow auto-numbered fields in str.format(). For
764 example: '{} {}'.format(1, 2) == '1 2'.
765
Brett Cannon6c4cff02009-03-11 04:51:06 +0000766- Issue #3652: Make the 'line' argument for warnings.showwarning() a
767 requirement. Means the DeprecationWarning from Python 2.6 can go away.
768
Eric Smithe9fb6862009-02-20 14:02:36 +0000769- Issue #5247: Improve error message when unknown format codes are
770 used when using str.format() with str, unicode, long, int, and
771 float arguments.
772
Raymond Hettinger08259e82009-02-18 23:10:19 +0000773- Running Python with the -3 option now also warns about classic division
774 for ints and longs.
775
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000776- Issue #5260: Long integers now consume less memory: average
777 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
778 on a 64-bit system.
779
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000780- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
781 rotating the object pointer by 4 bits to the right.
782
Mark Dickinsonc97c9092009-02-09 14:18:43 +0000783- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
784 it now forces its argument to double before testing for infinity.
785
Benjamin Petersone18ef192009-01-20 14:21:16 +0000786- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
787
Georg Brandl29c6a282009-04-05 20:23:13 +0000788- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000789 were suppressing all exceptions. These include list(), filter(), map(),
790 zip(), and bytearray().
791
Benjamin Peterson596d3062009-01-19 15:42:23 +0000792- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
793 functions.
794
Benjamin Peterson5848d1f2009-01-19 00:08:08 +0000795- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an

799
Antoine Pitrouc2f02212009-01-13 23:13:52 +0000800- Issue #4935: The overflow checking code in the expandtabs() method common
801 to str, bytes and bytearray could be optimized away by the compiler, letting
802 the interpreter segfault instead of raising an error.

810
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000811- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
812 collecting the oldest generation) so that allocating lots of objects without
813 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +0000814 Martin von Löwis at

Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000819- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
820 an existing .py counterpart, override the co_filename attributes of all
821 code objects if the original filename is obsolete (which can happen if the
822 file has been renamed, moved, or if it is accessed through different paths).
823 Patch by Ziga Seilnacht and Jean-Paul Calderone.

834 where the tp_hash and tp_dict slots are both NULL.
835
Benjamin Peterson7af65562008-12-29 17:56:58 +0000836- Issue #4764: With io.open, IOError.filename is set when trying to open a

864 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
865 str instances. On a typical machine this saves 3 bytes of memory
866 (on average) per string allocation.
867
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000868- Issue #3996: On Windows, the PyOS_CheckStack function would cause the

Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000879 method on file objects with closefd=False. The file descriptor is still
880 kept open but the file object behaves like a closed file. The ``FileIO``
881 object also got a new readonly attribute ``closefd``.

Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000904- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
905 returned a path longer than MAX_PATH. (But It's doubtful this code path is
906 really executed because I cannot move to such directory on win2k)
907
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000908- Issue #4069: When set.remove(element) is used with a set element, the element
909 is temporarily replaced with an equivalent frozenset. But the eventual
910 KeyError would always report the empty frozenset([]) as the missing key. Now
911 it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +0000931- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
932 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
933 step. This avoids problems with counting UTF-8 bytes that ignores the effect
934 of using the replace error handler in PyUnicode_DecodeUTF8().
935
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000936- Issue #3739: The unicode-internal encoder now reports the number of characters

938
Benjamin Peterson91c12eb2009-12-03 02:52:39 +0000939- Issue #2422: When compiled with the ``--with-valgrind`` option, the
940 pymalloc allocator will be automatically disabled when running under
941 Valgrind. This gives improved memory leak detection when running
942 under Valgrind, while taking advantage of pymalloc at other times.

Nick Coghlan49868cb2009-11-15 07:30:34 +00001011- Issue #6816: runpy now provides a run_path function that allows Python code
1012 to execute file paths that refer to source or compiled Python files as well
1013 as zipfiles, directories and other valid sys.path entries that contain a

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002322- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2323
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002324- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2325 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2326 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2327 ``printf`` function, whereas PyString_FromFormat has an independent
2328 implementation and uses "%zd" on all platforms for size_t values.
2329 This makes a difference on win64, where ``printf`` needs "%Id" to display
2330 64bit values.
2331
Benjamin Peterson97179b02008-09-09 20:55:01 +00002332- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
2333 error.
2334
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00002335- Issue #3777: long() applied to a float object now always return a long
2336 object; previously an int would be returned for small values. the __long__
2337 method is allowed to return either an int or a long, but the behaviour of
2338 float objects should not change to respect backward compatibility.
2339
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002340- Issue #3751: str.rpartition would perform a left-partition when called with
2341 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +00002346 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002347 was correctly parsed but parsing of subsequent arguments failed.
2348
Vinay Sajip35e3b032008-09-01 14:33:59 +00002349- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002350 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2351 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2352 when given a tuple of classes as second argument, were looking up
2353 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2354 type object.
2355
Neal Norwitz18aa3882008-08-24 05:04:52 +00002356- Fix crashes on memory allocation failure found with failmalloc.

2425 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2426 for catch_warnings() also led to an improvement in the raising of a

2499-----------------
2500
Guido van Rossumf8402962008-08-20 15:01:50 +00002501- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2502 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2503 extensions do not automatically benefit from the class attribute
2504 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2505 to their tp_flags field if they care. This is a backwards
2506 compatibility feature; in 3.0, all types will use the cache by
2507 default.
2508
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002509- Keyword arguments can now follow starred arguments. (``f(a, *args,
2510 keyword=23)`` is now valid syntax.)
2511
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002512- ctypes function pointers that are COM methods have a boolean True
2513 value again.
2514
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002515- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2516 by denying s# to parse objects that have a releasebuffer procedure,
2517 and introducing s*.
2518
Georg Brandl1e13ea92008-08-11 09:07:59 +00002519- Issue #3537: Fix an assertion failure when an empty but presized dict
2520 object was stored in the freelist.
2521
Mark Dickinsonb6467572008-08-04 21:30:09 +00002522- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2523 ValueError consistently across platforms.
2524
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002525- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2526 (64bit Unix, for example), unichr() would truncate its argument and return
2527 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2528
Neal Norwitze7d8be82008-07-31 17:17:14 +00002529- Apply security patches from Apple.
2530
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002531- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2532 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2533
Antoine Pitrou92f82162008-07-25 22:22:08 +00002534- Issue #1819: function calls with several named parameters are now on
2535 average 35% faster (as measured by pybench).
2536
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002537- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2538 the python debugger steps into a class statement: the free variables (local
2539 variables defined in an outer scope) would be deleted from the outer scope.
2540
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002541- Issue #2620: Overflow checking when allocating or reallocating memory
2542 was not always being done properly in some python types and extension
2543 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2544 all been updated to perform better checks and places in the code that
2545 would previously leak memory on the error path when such an allocation
2546 failed have been fixed.

2552
Benjamin Petersone977ad42008-08-20 01:42:01 +00002553- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2554 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2555
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002556- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2557 version reported by these tools does not necessarily follow the python
2558 version numbering scheme, so the module is less strict when parsing it.
2559
Nick Coghlanf70385a2008-08-18 12:42:46 +00002560- Issue #2235: Added Py3k warnings for types which will become unhashable
2561 under the stricter __hash__ inheritance rules in 3.0. Several types

Antoine Pitroude781a42008-08-09 12:43:23 +00002636 asking for a specific length. This problem only affected files opened

2680
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002681- Issue #643841: The language reference now provides more detailed

2693-----------------
2694
Georg Brandl3e483f62008-07-16 22:57:41 +00002695- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2696 its methods now allow for items objects that can be converted to
2697 an integer using operator.index().
2698
Mark Dickinson64b7e502008-07-16 09:40:03 +00002699- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2700 produced a ValueError instead of giving the correct float.
2701
Eric Smitha5fa5a22008-07-16 00:11:49 +00002702- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2703 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2704
Mark Dickinson7103aa42008-07-15 19:08:33 +00002705- Issue #3008: the float type has a new instance method 'float.hex'
2706 and a new class method 'float.fromhex' to convert floating-point
2707 numbers to and from hexadecimal strings, respectively.
2708
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002709- Issue #2235: __hash__ is once again inherited by default. To allow
2710 collections.Hashable to remain meaningful in the presence of the
2711 default hash implementation (object.__hash__), it is now possible
2712 to explicit block inheritance of hash by setting __hash__=None at
2713 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2714 level.
2715
Nick Coghlanb028f502008-07-13 14:52:36 +00002716- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2717 the parent module cannot be found while performing an absolute import.
2718 This means that an incorrectly defined __package__ attribute will
2719 now only prevent relative imports in that module rather than causing
2720 all imports from that module to fail.
2721
Nick Coghlan14ff9942008-07-08 14:21:42 +00002722- Issue #2517: Allow unicode messages in Exceptions again by correctly

2732 another thread's dictionary.
2733
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002734- Issue #3004: Minor change to slice.indices(): the start and stop
2735 arguments are now treated identically, making the behaviour easier
2736 to describe and understand. For example, slice(None, -10,
2737 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2738 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2739 10, -1).
2740
Georg Brandl278fc502008-07-19 12:46:12 +00002741- Issue #3219: Calling a function with repeated keyword arguments,
2742 f(a=2, a=23), would not cause a syntax error. This was a regression
2743 from 2.4 caused by the switch to the new compiler.

2746 other freelists. Changes their CompactFreeList apis into

2755
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002756- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002781- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2782 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002783 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002784 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002800- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Ronald Oussoren5640ce22008-06-05 12:58:24 +00003191- On MacOS X it is now possible to install the framework in 64-bit
3192 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00003193 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003194
3195 This is controlled by the configure argument ``--with-universal-archs``:
3196
3197 - ``--with-universal-archs=all``: install 4-way universal
3198
3199 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3200
3201 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3202
3203 This option should be used in combination with ``--enable-universalsdk=``.
3204
3205 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 +00003255- Issue #1631171: Re-implement the 'warnings' module in C (the
3256 original Python code has been kept as backup). This will allow for
3257 using the 'warning's machinery in such places as the parser where
3258 use of pure Python code is not possible. Both the ``showarning()``
3259 and ``formatwarning()`` gain an optional 'line' argument which is
3260 not called by default for backwards-compatibility reasons. Setting
3261 ``warnings.showwarning()`` to an implementation that lacks support
3262 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003325- Issue #2550: The approach used by client/server code for obtaining
3326 ports to listen on in network-oriented tests has been refined in an
3327 effort to facilitate running multiple instances of the entire
3328 regression test suite in parallel without issue.
3329 test_support.bind_port() has been fixed such that it will always
3330 return a unique port -- which wasn't always the case with the
3331 previous implementation, especially if socket options had been set
3332 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3333 new implementation of bind_port() will actually raise an exception
3334 if it is passed an AF_INET/SOCK_STREAM socket with either the
3335 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3336 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3337 the socket it's been passed. This currently only applies to
3338 Windows. This option prevents any other sockets from binding to the
3339 host/port we've bound to, thus removing the possibility of the
3340 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3341 when a second SOCK_STREAM socket binds and accepts to a host/port
3342 that's already been bound by another socket. The optional preferred
3343 port parameter to bind_port() has been removed. Under no
3344 circumstances should tests be hard coding ports!
3345
3346 test_support.find_unused_port() has also been introduced, which will
3347 pass a temporary socket object to bind_port() in order to obtain an
3348 unused port. The temporary socket object is then closed and
3349 deleted, and the port is returned. This method should only be used
3350 for obtaining an unused port in order to pass to an external program
3351 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3352 a parameter to a server-oriented class that doesn't give you direct
3353 access to the underlying socket used.
3354
3355 Finally, test_support.HOST has been introduced, which should be used
3356 for the host argument of any relevant socket calls (i.e. bind and
3357 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003358
3359 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003360 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003361 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3362 test_asynchat and test_socket_ssl.
3363
Georg Brandl3ee81df2008-05-17 18:14:43 +00003364 It is now possible for multiple instances of the regression test
3365 suite to run in parallel without issue.

3418
Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00003419- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00003420 \Uxxxxxxxx did not accept values outside the Basic Multilingual
3421 Plane. This affected raw unicode literals and the
3422 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
3423 this case, like normal unicode literals and the 'unicode-escape'
3424 codec.

3632-----------------
3633
Fred Drakea8ee94b2008-03-01 02:45:07 +00003634- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003635 644. The mode is now inherited from the py file.

3638
3639- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003640
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003641- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003642 issue 215555 for a discussion.
3643
Eric Smitha73fbe72008-02-23 03:09:44 +00003644- Added the future_builtins module, which contains hex() and oct().
3645 These are the PEP 3127 version of these functions, designed to be
3646 compatible with the hex() and oct() builtins from Python 3.0. They
3647 differ slightly in their output formats from the existing, unchanged
3648 Python 2.6 builtins. The expected usage of the future_builtins
3649 module is:
3650 from future_builtins import hex, oct
3651
Eric Smith7ef40bf2008-02-20 23:34:22 +00003652- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3653 exponents for exponents with absolute value < 100. Follows C99
3654 standard. This is a change on Windows, which would use 3 digits.
3655 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3656 so that any alterations it does to the resulting string will be
3657 available in stringlib/formatter.h (for float.__format__).
3658
Eric Smith5a3c1352008-02-19 13:21:56 +00003659- Implemented PEP 3101, Advanced String Formatting. This adds a new
3660 builtin format(); a format() method for str and unicode; a
3661 __format__() method to object, str, unicode, int, long, float, and
3662 datetime; the class string.Formatter; and the C API
3663 PyObject_Format().
3664
Georg Brandl3ee81df2008-05-17 18:14:43 +00003665- Fixed several potential crashes, all caused by specially crafted
3666 __del__ methods exploiting objects in temporarily inconsistent
3667 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003668
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003669- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003670 prevent a possible crash: an Abstract Base Class would try to access
3671 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003672

Georg Brandl3ee81df2008-05-17 18:14:43 +00003676- Clear all free lists during a gc.collect() of the highest generation
3677 in order to allow pymalloc to free more arenas. Python may give back
3678 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003679
Georg Brandl3ee81df2008-05-17 18:14:43 +00003680- Issue #2045: Fix an infinite recursion triggered when printing a

3695 calls. Python expected the return type int but the fork familie
3696 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003697
Georg Brandl3ee81df2008-05-17 18:14:43 +00003698- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00003710- Patch #1473257: generator objects gain a gi_code attribute. This is
3711 the same object as the func_code attribute of the function that
3712 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003713
Georg Brandl3ee81df2008-05-17 18:14:43 +00003714- Issue #1920: "while 0" statements were completely removed by the
3715 compiler, even in the presence of an "else" clause, which is
3716 supposed to be run when the condition is false. Now the compiler
3717 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003718
Guido van Rossumeead05f2008-01-24 18:21:02 +00003719- A few crashers fixed: weakref_in_del.py (issue #1377858);
3720 loosing_dict_ref.py (issue #1303614, test67.py);
3721 borrowed_ref_[34].py (not in tracker).

Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003723- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003724 suppressed while an extension is loaded by calling SetErrorMode in
3725 dynload_win.c. The error is still reported properly.
3726
Georg Brandl3ee81df2008-05-17 18:14:43 +00003727- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003728 several extension methods and modules do not work without unicode
3729 support.
3730
Georg Brandl26543b12008-01-21 18:36:51 +00003731- Issue #1882: when compiling code from a string, encoding cookies in the

3735
Georg Brandl6caad7d2008-01-26 14:19:22 +00003736- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003737 added.
3738
Christian Heimesc94e2b52008-01-14 04:13:37 +00003739- sys.float_info / PyFloat_GetInfo: The floating point information
3740 object was converted from a dict to a specialized structseq object.
3741
Georg Brandl3ee81df2008-05-17 18:14:43 +00003742- Patch #1816: Added sys.flags structseq. It exposes the status of
3743 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003744
Georg Brandl3ee81df2008-05-17 18:14:43 +00003745- Objects/structseq.c: Implemented new structseq representation. The
3746 patch makes structseqs (e.g. the return value of os.stat) more
3747 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003748
Georg Brandl3ee81df2008-05-17 18:14:43 +00003749- Patch #1700288: added a type attribute cache that caches method
3750 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003751
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003752- Bug #1776: __import__() no longer accepts filenames on any platform.
3753 The first parameter to __import__() must be a valid module name.

3758 envvar and sys.dont_write_bytecode attribute. All these can be set
3759 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003760
Georg Brandl3ee81df2008-05-17 18:14:43 +00003761- Improve some exception messages when Windows fails to load an
3762 extension module. Now we get for example '%1 is not a valid Win32
3763 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003764

3820
Georg Brandl3ee81df2008-05-17 18:14:43 +00003821- The enumerate() builtin function is no longer bounded to sequences
3822 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3823 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003824
Georg Brandl3ee81df2008-05-17 18:14:43 +00003825- Issue #1686386: Tuple's tp_repr did not take into account the
3826 possibility of having a self-referential tuple, which is possible
3827 from C code. Nor did object's tp_str consider that a type's tp_str
3828 could do something that could lead to an inifinite recursion.
3829 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3830 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003831
Georg Brandl3ee81df2008-05-17 18:14:43 +00003832- Issue #1164: It was possible to trigger deadlock when using the
3833 'print' statement to write to a file since the GIL was not released
3834 as needed. Now PyObject_Print() does the right thing along with
3835 various tp_print implementations of the built-in types and those in
3836 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003846 PyObject_Call() never calling back out to Python code to trigger
3847 recursion depth updates/checks. Required the creation of a static
3848 RuntimeError instance in case normalizing an exception put the
3849 recursion check value past its limit. Fixes crashers

3899 now stricter in rejecting excess arguments. The only time when
3900 either allows excess arguments is when it is not overridden and the
3901 other one is. For backwards compatibility, when both are
3902 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003903 warning later). Also, type.__init__() insists on the same signature
3904 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00003906- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3907 object to complex using its __complex__() method before falling back
3908 to the __float__() method. Therefore, the functions in the cmath
3909 module now can operate on objects that define a __complex__()
3910 method.

3930
Georg Brandl871f1bc2007-03-12 13:17:36 +00003931- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003932 its argument, if it exists. If not, it will work like before. This
3933 allows customizing the output of dir() in the presence of a
3934 __getattr__().

Georg Brandlaa2321b2007-03-07 00:40:28 +00003946- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003947 makes the filenames the warning module prints much more sensible
3948 when a PYTHONSTARTUP file is used.

3962 sq_ass_slice instead of the sq_slice slot.
3963
Georg Brandl3ee81df2008-05-17 18:14:43 +00003964- When printing an unraisable error, don't print exceptions. before

Georg Brandl2c1375c2006-10-12 11:27:59 +00004016- Bug #1545497: when given an explicit base, int() did ignore NULs
4017 embedded in the string to convert.
4018
Georg Brandl846f73a2006-10-08 07:11:54 +00004019- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00004067 generator expressions (x for x, in ... ) works again. Fixing this
4068 problem required changing the .pyc magic number. This means that
4069 .pyc files generated before 2.5c2 will be regenerated.

4874 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00004875
Georg Brandl3ee81df2008-05-17 18:14:43 +00004876- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4877 with RFC 3207 and forgets any knowledge obtained from the server not
4878 obtained from the TLS negotiation itself. Patch contributed by Bill
4879 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004880
Georg Brandl3ee81df2008-05-17 18:14:43 +00004881- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004882 that the SMTP.starttls() caller no longer needs to call ehlo()
4883 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004884 does not claim to support starttls. Adds the
4885 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
4886 Fenner.

4966 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4967 silently miscode subclasses of those types. Now, it raises a
4968 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00004969

Georg Brandl3ee81df2008-05-17 18:14:43 +00004984 time so that opening a database previously created with the DB_DUP
4985 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4986 opens. Specifically: dictionary assignment to a DB object will
4987 replace all values for a given key when the database allows
4988 duplicate values. DB users should use DB.put(k, v) when they want
4989 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004990

4996 characters with ASCII value less than 32. Also, it correctly quotes
4997 dots only if they occur on a single line, as opposed to the previous
4998 behavior of quoting dots if they are the second character of any
4999 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00005000
