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

Georg Brandlba83f822010-03-14 09:50:54 +0000253- Issue #7712: test_support gained a new ``temp_cwd`` context manager which is
254 now also used by regrtest to run all the tests in a temporary directory. The
255 original CWD is saved in ``test.test_support.SAVEDCWD``. Thanks to Florent
256 Xicluna who helped with the patch.

273 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +0000274 library would return a bogus result; on Solaris, it was possible to crash the
275 interpreter. Patch by Stefan Krah.

289 and add the additional members returned in an OSVERSIONINFOEX structure. The
290 new members are service_pack_major, service_pack_minor, suite_mask, and

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

Antoine Pitroud840e512010-02-04 20:20:18 +0000338- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +0000339 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +0000340 Also, raise ValueError rather than TypeError when an unknown TIPC address
341 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000345- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +0000346 file position when calling `truncate()`. It would previously change the file
347 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000348 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
349
Benjamin Petersone06f7112010-01-28 02:15:02 +0000350- UserDict is now a new-style class.
351
Georg Brandlba83f822010-03-14 09:50:54 +0000352- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
353 class used to represent files stored inside an archive. The new
354 implementation is significantly faster and can be wrapped in a
355 ``io.BufferedReader`` object for more speedups. It also solves an issue
356 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
357 Patch by Nir Aides.

365 when the release file is empty.
Benjamin Petersona43f34c2010-01-25 03:31:13 +0000366
Georg Brandlba83f822010-03-14 09:50:54 +0000367- Issue #7748: Since unicode values are supported for some metadata options in
368 Distutils, the DistributionMetadata get_* methods will now return an utf-8
369 encoded string for them. This ensures that the upload and register commands
370 send the correct values to PyPI without any error.

446
Georg Brandlba83f822010-03-14 09:50:54 +0000447- The ``__complex__()`` method is now looked up on the class of instances to
448 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000450- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
451 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
452
Mark Dickinson1b34d252010-01-01 17:27:30 +0000453- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000454 DeprecationWarning when passed a float argument where an integer was expected.
455 These functions and methods now raise TypeError instead. The majority of the
456 effects of this change are in the extension modules, but some core functions
457 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
458 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +0000471- Issue #1811: Improve accuracy and cross-platform consistency for true division
472 of integers: the result of a/b is now correctly rounded for ints a and b (at
473 least on IEEE 754 platforms), and in particular does not depend on the
474 internal representation of a long.

482
Georg Brandlba83f822010-03-14 09:50:54 +0000483 These executables now work properly with the arch(1) command: ``arch -ppc
484 python`` will start a universal binary version of python in PPC mode (unlike
485 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +0000641- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
642 decimal string that's guaranteed to round back to x under correct rounding
643 (with round-half-to-even rounding mode). Previously it gave a string based on
644 rounding x to 17 decimal digits. repr(x) for a complex number behaves
645 similarly. On platforms where the correctly-rounded strtod and dtoa code is
646 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000647
Georg Brandlba83f822010-03-14 09:50:54 +0000648- Issue #7117: On almost all platforms: float-to-string and string-to-float
649 conversions within Python are now correctly rounded. Places these conversions
650 occur include: str for floats and complex numbers; the float and complex
651 constructors; old-style and new-style numeric formatting; serialization and
652 deserialization of floats and complex numbers using marshal, pickle and json;
653 parsing of float and imaginary literals in Python code; Decimal-to-float
654 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000655
Georg Brandlba83f822010-03-14 09:50:54 +0000656 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
657 providing correctly-rounded strtod and dtoa C functions. This code is
658 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
659 the C compiler. There may be a small number of platforms on which correct
660 operation of this code cannot be guaranteed, so the code is not used: notably,
661 this applies to platforms where the C double format is not IEEE 754 binary64,
662 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
663 and Python's configure script is unable to determine how to change the FPU
664 precision. On these platforms conversions use the platform strtod and dtoa,
665 as before.

Georg Brandlba83f822010-03-14 09:50:54 +0000667- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
668 uses the correctly-rounded string <-> float conversions described above (when
669 available), and so produces correctly rounded results that will display nicely
670 under the float repr. There are two related small changes: (1) round now
671 accepts any class with an ``__index__()`` method for its second argument (but
672 no longer accepts floats for the second argument), and (2) an excessively
673 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
674 raises an exception.

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

986
Benjamin Petersonfe231b02008-12-29 17:47:42 +0000987- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
988 systems.
989
Georg Brandl6425a2f2008-12-28 11:54:53 +0000990- Issue #4759: None is now allowed as the first argument of
Georg Brandlba83f822010-03-14 09:50:54 +0000991 ``bytearray.translate()``. It was always allowed for ``bytes.translate()``.
Georg Brandl6425a2f2008-12-28 11:54:53 +0000992
Skip Montanarof205c132008-12-23 03:30:15 +0000993- Added test case to ensure attempts to read from a file opened for writing
994 fail.
995
Georg Brandlba83f822010-03-14 09:50:54 +0000996- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always print
997 elapsed times, not only when some objects are uncollectable/unreachable.
998 Original patch by Neil Schemenauer.

Georg Brandlba83f822010-03-14 09:50:54 +00001010- Issue #4445: Replace ``sizeof(PyStringObject)`` with
1011 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
1012 instances. On a typical machine this saves 3 bytes of memory (on average) per
1013 string allocation.

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00001015- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1016 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1017 instead of throwing a MemoryError.
1018
Georg Brandlba83f822010-03-14 09:50:54 +00001019- Issue #3689: The list reversed iterator now supports __length_hint__ instead
1020 of __len__. Behavior now matches other reversed iterators.
Raymond Hettinger7989a4d2008-12-03 15:42:10 +00001021
Benjamin Petersonc078f922008-11-21 22:27:24 +00001022- Issue #4367: Python would segfault during compiling when the unicodedata
1023 module couldn't be imported and \N escapes were present.
1024
Georg Brandlba83f822010-03-14 09:50:54 +00001025- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
1026 file objects with closefd=False. The file descriptor is still kept open but
1027 the file object behaves like a closed file. The ``FileIO`` object also got a
1028 new readonly attribute ``closefd``.

Benjamin Peterson46cc6d12008-11-19 21:49:09 +00001030- Issue #4348: Some bytearray methods returned that didn't cause any change to
1031 the bytearray, returned the same bytearray instead of a copy.
1032
Georg Brandlba83f822010-03-14 09:50:54 +00001033- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.

1036
Benjamin Peterson6624a9f2008-11-03 15:14:51 +00001037- Issue #4048: The parser module now correctly validates relative imports.
1038
Benjamin Petersondcee09d2008-10-31 02:16:05 +00001039- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

1041
Georg Brandlba83f822010-03-14 09:50:54 +00001042- Issue #4176: Fixed a crash when pickling an object which ``__reduce__`` method

Benjamin Petersonbdca9422008-10-26 20:21:13 +00001045- Issue #4209: Enabling unicode_literals and the print_function in the same
1046 __future__ import didn't work.
1047
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00001048- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00001049 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00001050
Georg Brandlba83f822010-03-14 09:50:54 +00001051- On windows, ``os.chdir()`` given unicode was not working if
1052 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
1053 this code path is really executed because I cannot move to such directory on
1054 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00001055
Georg Brandlba83f822010-03-14 09:50:54 +00001056- Issue #4069: When ``set.remove(element)`` is used with a set element, the
1057 element is temporarily replaced with an equivalent frozenset. But the
1058 eventual KeyError would always report the empty ``frozenset()`` as the missing
1059 key. Now it correctly refers to the initial element.
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +00001060
Georg Brandlba83f822010-03-14 09:50:54 +00001061- Issue #4509: Various issues surrounding resize of bytearray objects to which

Matthias Klose91a3b9e2009-04-05 21:19:13 +00001073- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1074 to avoid compiler warnings.
Matthias Klose0610e082009-04-05 12:43:08 +00001075
Gregory P. Smith2b3eb372009-04-05 23:48:26 +00001076- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
1077 returned them on 64bit platforms.
1078
Walter Dörwalded960ac2009-05-03 22:36:33 +00001079- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
1080 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1081 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1082 of using the replace error handler in PyUnicode_DecodeUTF8().
1083
Walter Dörwald726ba8e2009-05-06 14:32:35 +00001084- Issue #3739: The unicode-internal encoder now reports the number of characters
1085 consumed like any other encoder (instead of the number of bytes).
1086
Georg Brandlba83f822010-03-14 09:50:54 +00001087- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
1088 allocator will be automatically disabled when running under Valgrind. This
1089 gives improved memory leak detection when running under Valgrind, while taking
1090 advantage of pymalloc at other times.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002455- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2456
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002457- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2458 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2459 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2460 ``printf`` function, whereas PyString_FromFormat has an independent
2461 implementation and uses "%zd" on all platforms for size_t values.
2462 This makes a difference on win64, where ``printf`` needs "%Id" to display
2463 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00002465- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

2469 object; previously an int would be returned for small values. the __long__
2470 method is allowed to return either an int or a long, but the behaviour of

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002473- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +00002479 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002480 was correctly parsed but parsing of subsequent arguments failed.
2481
Vinay Sajip35e3b032008-09-01 14:33:59 +00002482- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002483 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2484 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2485 when given a tuple of classes as second argument, were looking up
2486 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2487 type object.
2488
Neal Norwitz18aa3882008-08-24 05:04:52 +00002489- Fix crashes on memory allocation failure found with failmalloc.

2632-----------------
2633
Guido van Rossumf8402962008-08-20 15:01:50 +00002634- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2635 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2636 extensions do not automatically benefit from the class attribute
2637 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2638 to their tp_flags field if they care. This is a backwards
2639 compatibility feature; in 3.0, all types will use the cache by
2640 default.
2641
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002642- Keyword arguments can now follow starred arguments. (``f(a, *args,

Thomas Heller0ad5ae02008-08-19 19:25:04 +00002645- ctypes function pointers that are COM methods have a boolean True
2646 value again.
2647
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002648- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2649 by denying s# to parse objects that have a releasebuffer procedure,
2650 and introducing s*.

Mark Dickinsonb6467572008-08-04 21:30:09 +00002655- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2656 ValueError consistently across platforms.
2657
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002658- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2659 (64bit Unix, for example), unichr() would truncate its argument and return
2660 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2661
Neal Norwitze7d8be82008-07-31 17:17:14 +00002662- Apply security patches from Apple.
2663
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002664- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2665 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2666
Antoine Pitrou92f82162008-07-25 22:22:08 +00002667- Issue #1819: function calls with several named parameters are now on
2668 average 35% faster (as measured by pybench).
2669
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002670- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2671 the python debugger steps into a class statement: the free variables (local
2672 variables defined in an outer scope) would be deleted from the outer scope.
2673
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002674- Issue #2620: Overflow checking when allocating or reallocating memory
2675 was not always being done properly in some python types and extension
2676 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2677 all been updated to perform better checks and places in the code that
2678 would previously leak memory on the error path when such an allocation
2679 failed have been fixed.

2688
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002689- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2690 version reported by these tools does not necessarily follow the python
2691 version numbering scheme, so the module is less strict when parsing it.
2692
Nick Coghlanf70385a2008-08-18 12:42:46 +00002693- Issue #2235: Added Py3k warnings for types which will become unhashable
2694 under the stricter __hash__ inheritance rules in 3.0. Several types
2695 which did not meet the rules for hash invariants and were already
2696 unhashable in 3.0 have now been explicitly flagged as unhashable in
2697 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2698 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2699
Brett Cannon88f801d2008-08-18 00:46:22 +00002700- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

2722 after a 302 response in the case of not going through a proxy.
2723
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002724- Issue #2676: in the email package, content-type parsing was hanging on

2726 regular expression.
2727
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002728- Issue #3476: binary buffered reading through the new "io" library is now
2729 thread-safe.
2730
Brett Cannonbf3157b2008-08-14 05:00:03 +00002731- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2732 since mimetools itself is deprecated. Because modules are cached, all
2733 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2734
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002735- Issue #3134: shutil referenced undefined WindowsError symbol.

2744 a MemoryError rather than silently stop the iteration.
2745
Guido van Rossum59ce9012008-08-09 14:55:34 +00002746- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2747 to _sre.compile() will now be rejected. This should not affect anybody
2748 since the re.compile() function never generates invalid re-bytecode.
2749
Skip Montanaroa032bf42008-08-08 22:52:51 +00002750- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2751 upon first access it can be automatically initialized from the csv file if
2752 it wasn't initialized during instantiation.
2753
Brett Cannon3aa2a492008-08-06 22:28:09 +00002754- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2755 the reload() built-in has been removed.
2756
Brett Cannon7e30b672008-08-04 21:52:25 +00002757- Changed code in the following modules/packages to remove warnings raised

2766 raised an AttributeError.
2767
Benjamin Peterson01a24322008-07-28 23:35:27 +00002768- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002769 asking for a specific length. This problem only affected files opened
2770 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002771

2794
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002795- Issue #3394: zipfile.writestr sets external attributes when passed a
2796 file name rather than a ZipInfo instance, so files are extracted with
2797 mode 0600 rather than 000 under Unix.
2798
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002799- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2800 argument in python 2.5, this broke code that subclassed Popen to include its

Nick Coghlan6e8fef02008-08-18 13:14:22 +00002811- Issue #2235: the C API function PyObject_HashNotImplemented and its
2812 interaction with the tp_hash slot (added in 2.6b2) are now documented
2813
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002814- Issue #643841: The language reference now provides more detailed
2815 coverage of the lookup process for special methods. The disclaimers
2816 regarding lack of coverage of new-style classes have also been
2817 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00002825Core and Builtins
2826-----------------
2827
Georg Brandl3e483f62008-07-16 22:57:41 +00002828- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2829 its methods now allow for items objects that can be converted to
2830 an integer using operator.index().
2831
Mark Dickinson64b7e502008-07-16 09:40:03 +00002832- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2833 produced a ValueError instead of giving the correct float.
2834
Eric Smitha5fa5a22008-07-16 00:11:49 +00002835- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2836 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2837
Mark Dickinson7103aa42008-07-15 19:08:33 +00002838- Issue #3008: the float type has a new instance method 'float.hex'
2839 and a new class method 'float.fromhex' to convert floating-point
2840 numbers to and from hexadecimal strings, respectively.
2841
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002842- Issue #2235: __hash__ is once again inherited by default. To allow
2843 collections.Hashable to remain meaningful in the presence of the
2844 default hash implementation (object.__hash__), it is now possible
2845 to explicit block inheritance of hash by setting __hash__=None at
2846 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2847 level.
2848
Nick Coghlanb028f502008-07-13 14:52:36 +00002849- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2850 the parent module cannot be found while performing an absolute import.
2851 This means that an incorrectly defined __package__ attribute will
2852 now only prevent relative imports in that module rather than causing
2853 all imports from that module to fail.
2854
Nick Coghlan14ff9942008-07-08 14:21:42 +00002855- Issue #2517: Allow unicode messages in Exceptions again by correctly
2856 bypassing the instance dictionary when looking up __unicode__ on
2857 new-style classes.
2858
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002859- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2860 set to a custom object whose write() method happens to install
2861 another file in sys.stdout.
2862
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002863- Issue #3088: Corrected a race condition in classes derived from
2864 threading.local: the first member set by a thread could be saved in
2865 another thread's dictionary.
2866
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002867- Issue #3004: Minor change to slice.indices(): the start and stop
2868 arguments are now treated identically, making the behaviour easier
2869 to describe and understand. For example, slice(None, -10,
2870 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2871 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2872 10, -1).
2873
Georg Brandl278fc502008-07-19 12:46:12 +00002874- Issue #3219: Calling a function with repeated keyword arguments,
2875 f(a=2, a=23), would not cause a syntax error. This was a regression
2876 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002877
Georg Brandl278fc502008-07-19 12:46:12 +00002878- Issue #2862: Make int and float freelist management consistent with
2879 other freelists. Changes their CompactFreeList apis into
2880 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00002881

2884
Thomas Heller57adf222008-08-14 19:10:48 +00002885- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2886 api functions without holding the GIL, which could lead to a fatal
2887 error when they failed.
2888
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002889- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

2898 ForkingPickler.register() to resolve conflict with ctypes.
2899
Vinay Sajip51e65192008-07-18 09:01:10 +00002900- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

2903 a valid dlerror() message.
2904
Thomas Heller2bad6572008-07-15 17:19:50 +00002905- Issue #3258: Fixed a crash when a ctypes POINTER type to an
2906 incomplete structure was created.
2907

2911
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002912- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00002913
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002914- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2915 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002916 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002917 content-length. The problem had been corrected in the 2.4 branch, but never
2918 merged into trunk.
2919
Georg Brandle78fbcc2008-07-05 10:13:36 +00002920- Issue #2663: add filtering capability to shutil.copytree().

3325 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00003326 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003327
3328 This is controlled by the configure argument ``--with-universal-archs``:
3329
3330 - ``--with-universal-archs=all``: install 4-way universal
3331
3332 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3333
3334 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3335
3336 This option should be used in combination with ``--enable-universalsdk=``.
3337
3338 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 +00003388- Issue #1631171: Re-implement the 'warnings' module in C (the
3389 original Python code has been kept as backup). This will allow for
3390 using the 'warning's machinery in such places as the parser where
3391 use of pure Python code is not possible. Both the ``showarning()``
3392 and ``formatwarning()`` gain an optional 'line' argument which is
3393 not called by default for backwards-compatibility reasons. Setting
3394 ``warnings.showwarning()`` to an implementation that lacks support
3395 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003458- Issue #2550: The approach used by client/server code for obtaining
3459 ports to listen on in network-oriented tests has been refined in an
3460 effort to facilitate running multiple instances of the entire
3461 regression test suite in parallel without issue.
3462 test_support.bind_port() has been fixed such that it will always
3463 return a unique port -- which wasn't always the case with the
3464 previous implementation, especially if socket options had been set
3465 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3466 new implementation of bind_port() will actually raise an exception
3467 if it is passed an AF_INET/SOCK_STREAM socket with either the
3468 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3469 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3470 the socket it's been passed. This currently only applies to
3471 Windows. This option prevents any other sockets from binding to the
3472 host/port we've bound to, thus removing the possibility of the
3473 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3474 when a second SOCK_STREAM socket binds and accepts to a host/port
3475 that's already been bound by another socket. The optional preferred
3476 port parameter to bind_port() has been removed. Under no
3477 circumstances should tests be hard coding ports!
3478
3479 test_support.find_unused_port() has also been introduced, which will
3480 pass a temporary socket object to bind_port() in order to obtain an
3481 unused port. The temporary socket object is then closed and
3482 deleted, and the port is returned. This method should only be used
3483 for obtaining an unused port in order to pass to an external program
3484 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3485 a parameter to a server-oriented class that doesn't give you direct
3486 access to the underlying socket used.
3487
3488 Finally, test_support.HOST has been introduced, which should be used
3489 for the host argument of any relevant socket calls (i.e. bind and
3490 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003491

3764Core and builtins
3765-----------------
3766
Fred Drakea8ee94b2008-03-01 02:45:07 +00003767- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003768 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00003769
Georg Brandlad61bc82008-02-23 15:11:18 +00003770- Issue #2067: file.__exit__() now calls subclasses' close() method.
3771
3772- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003773
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003774- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003775 issue 215555 for a discussion.
3776
Eric Smitha73fbe72008-02-23 03:09:44 +00003777- Added the future_builtins module, which contains hex() and oct().
3778 These are the PEP 3127 version of these functions, designed to be
3779 compatible with the hex() and oct() builtins from Python 3.0. They
3780 differ slightly in their output formats from the existing, unchanged
3781 Python 2.6 builtins. The expected usage of the future_builtins
3782 module is:
3783 from future_builtins import hex, oct
3784
Eric Smith7ef40bf2008-02-20 23:34:22 +00003785- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3786 exponents for exponents with absolute value < 100. Follows C99
3787 standard. This is a change on Windows, which would use 3 digits.
3788 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3789 so that any alterations it does to the resulting string will be
3790 available in stringlib/formatter.h (for float.__format__).
3791
Eric Smith5a3c1352008-02-19 13:21:56 +00003792- Implemented PEP 3101, Advanced String Formatting. This adds a new
3793 builtin format(); a format() method for str and unicode; a
3794 __format__() method to object, str, unicode, int, long, float, and
3795 datetime; the class string.Formatter; and the C API
3796 PyObject_Format().
3797
Georg Brandl3ee81df2008-05-17 18:14:43 +00003798- Fixed several potential crashes, all caused by specially crafted
3799 __del__ methods exploiting objects in temporarily inconsistent
3800 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003801
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003802- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003803 prevent a possible crash: an Abstract Base Class would try to access
3804 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003805
Georg Brandl3ee81df2008-05-17 18:14:43 +00003806- Fixed repr() and str() of complex numbers with infinity or nan as
3807 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003808
Georg Brandl3ee81df2008-05-17 18:14:43 +00003809- Clear all free lists during a gc.collect() of the highest generation
3810 in order to allow pymalloc to free more arenas. Python may give back
3811 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003812
Georg Brandl3ee81df2008-05-17 18:14:43 +00003813- Issue #2045: Fix an infinite recursion triggered when printing a
3814 subclass of collections.defaultdict, if its default_factory is set
3815 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003816
Christian Heimesf75dbef2008-02-08 00:11:31 +00003817- Fixed a minor memory leak in dictobject.c. The content of the free
3818 list was not freed on interpreter shutdown.
3819
Georg Brandl21e99f42010-03-07 15:23:59 +00003820- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003821 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003822
Georg Brandl3ee81df2008-05-17 18:14:43 +00003823- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3824 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003825 to compact the internal free lists of pre-allocted ints and floats.
3826
Georg Brandl3ee81df2008-05-17 18:14:43 +00003827- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3828 calls. Python expected the return type int but the fork familie
3829 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003830
Georg Brandl3ee81df2008-05-17 18:14:43 +00003831- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3832 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003833
Georg Brandl3ee81df2008-05-17 18:14:43 +00003834- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3835 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003836
Georg Brandl3ee81df2008-05-17 18:14:43 +00003837- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3838 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003839
Georg Brandl3ee81df2008-05-17 18:14:43 +00003840- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3841 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003842
Georg Brandl3ee81df2008-05-17 18:14:43 +00003843- Patch #1473257: generator objects gain a gi_code attribute. This is
3844 the same object as the func_code attribute of the function that
3845 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003846
Georg Brandl3ee81df2008-05-17 18:14:43 +00003847- Issue #1920: "while 0" statements were completely removed by the
3848 compiler, even in the presence of an "else" clause, which is
3849 supposed to be run when the condition is false. Now the compiler
3850 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003851
Guido van Rossumeead05f2008-01-24 18:21:02 +00003852- A few crashers fixed: weakref_in_del.py (issue #1377858);
3853 loosing_dict_ref.py (issue #1303614, test67.py);
3854 borrowed_ref_[34].py (not in tracker).
3855
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003856- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003857 suppressed while an extension is loaded by calling SetErrorMode in
3858 dynload_win.c. The error is still reported properly.
3859
Georg Brandl3ee81df2008-05-17 18:14:43 +00003860- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003861 several extension methods and modules do not work without unicode
3862 support.
3863
Georg Brandl26543b12008-01-21 18:36:51 +00003864- Issue #1882: when compiling code from a string, encoding cookies in the
3865 second line of code were not always recognized correctly.
3866
Georg Brandl14404b62008-01-19 19:27:05 +00003867- Issue #1679: "0x" was taken as a valid integer literal.
3868
Georg Brandl6caad7d2008-01-26 14:19:22 +00003869- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003870 added.
3871
Christian Heimesc94e2b52008-01-14 04:13:37 +00003872- sys.float_info / PyFloat_GetInfo: The floating point information
3873 object was converted from a dict to a specialized structseq object.
3874
Georg Brandl3ee81df2008-05-17 18:14:43 +00003875- Patch #1816: Added sys.flags structseq. It exposes the status of
3876 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003877
Georg Brandl3ee81df2008-05-17 18:14:43 +00003878- Objects/structseq.c: Implemented new structseq representation. The
3879 patch makes structseqs (e.g. the return value of os.stat) more
3880 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003881
Georg Brandl3ee81df2008-05-17 18:14:43 +00003882- Patch #1700288: added a type attribute cache that caches method
3883 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003884
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003885- Bug #1776: __import__() no longer accepts filenames on any platform.
3886 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003887
Georg Brandlaed6c662008-01-07 17:25:53 +00003888- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3889
Georg Brandl3ee81df2008-05-17 18:14:43 +00003890- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3891 envvar and sys.dont_write_bytecode attribute. All these can be set
3892 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003893
Georg Brandl3ee81df2008-05-17 18:14:43 +00003894- Improve some exception messages when Windows fails to load an
3895 extension module. Now we get for example '%1 is not a valid Win32
3896 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003897
Georg Brandl3ee81df2008-05-17 18:14:43 +00003898- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003900- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3901 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003902
Christian Heimes0a8143f2007-12-18 23:22:54 +00003903- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003904 and INF. float("nan"), float("inf") and float("-inf") now work on
3905 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003906
Georg Brandl3ee81df2008-05-17 18:14:43 +00003907- Compiler now generates simpler and faster code for dictionary
3908 literals. The oparg for BUILD_MAP now indicates an estimated
3909 dictionary size. There is a new opcode, STORE_MAP, for adding
3910 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00003911
Georg Brandl3ee81df2008-05-17 18:14:43 +00003912- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003917- Issue #1538: Avoid copying string in split/rsplit if the split char
3918 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00003919
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00003920- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00003921 SystemError.
3922
Nick Coghlanef01d822007-12-03 12:55:17 +00003923- PEP 366: Allow explicit relative imports when executing modules
3924 inside packages with the -m switch via a new module level
3925 __package__ attribute.
3926
Georg Brandl3ee81df2008-05-17 18:14:43 +00003927- Issue #1402: Fix a crash on exit, when another thread is still
3928 running, and if the deallocation of its frames somehow calls the
3929 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00003930

3932
Vinay Sajip2bdc48c2008-01-21 18:16:05 +00003933- Issue #1445: Fix a SystemError when accessing the ``cell_contents``
Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00003934 attribute of an empty cell object.
3935
Georg Brandl3ee81df2008-05-17 18:14:43 +00003936- Issue #1460: The utf-7 incremental decoder did not accept truncated
3937 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00003938
Georg Brandl3ee81df2008-05-17 18:14:43 +00003939- Patch #1739468: Directories and zipfiles containing a __main__.py
3940 file can now be directly executed by passing their name to the
3941 interpreter. The directory/zipfile is automatically inserted as the
3942 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003943
Georg Brandl3ee81df2008-05-17 18:14:43 +00003944- Issue #1265: Fix a problem with sys.settrace, if the tracing
3945 function uses a generator expression when at the same time the
3946 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003947
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003948- sets and frozensets now have an isdisjoint() method.
3949
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003950- optimize the performance of builtin.sum().
3951
Neal Norwitz44f326e2007-10-05 05:29:17 +00003952- Fix warnings found by the new version of the Coverity checker.
3953
Georg Brandl21e99f42010-03-07 15:23:59 +00003954- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003955 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3956 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003957
Georg Brandl3ee81df2008-05-17 18:14:43 +00003958- Issue #1686386: Tuple's tp_repr did not take into account the
3959 possibility of having a self-referential tuple, which is possible
3960 from C code. Nor did object's tp_str consider that a type's tp_str
3961 could do something that could lead to an inifinite recursion.
3962 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3963 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003964
Georg Brandl3ee81df2008-05-17 18:14:43 +00003965- Issue #1164: It was possible to trigger deadlock when using the
3966 'print' statement to write to a file since the GIL was not released
3967 as needed. Now PyObject_Print() does the right thing along with
3968 various tp_print implementations of the built-in types and those in
3969 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003970
Georg Brandl3ee81df2008-05-17 18:14:43 +00003971- Issue #1147: Exceptions were directly allowing string exceptions in
3972 their throw() method even though string exceptions no longer
3973 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003974
Georg Brandl3ee81df2008-05-17 18:14:43 +00003975- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00003978- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003979 PyObject_Call() never calling back out to Python code to trigger
3980 recursion depth updates/checks. Required the creation of a static
3981 RuntimeError instance in case normalizing an exception put the
3982 recursion check value past its limit. Fixes crashers
3983 infinite_rec_(1|2|4|5).py.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003999 __*__ attributes. (Some already existed, e.g., __doc__ and
4000 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004001
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004002- Add -3 option to the interpreter to warn about features that are

Georg Brandl3ee81df2008-05-17 18:14:43 +00004009 "except E as target:". This is to provide forwards compatibility
4010 with Python 3.0.

Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004018 setting a plain string, ie don't expand to single letter identifiers.
4019
Raymond Hettinger13936692007-04-11 18:40:58 +00004020- Request #1191699: Slices can now be pickled.

4030
Guido van Rossum143b5642007-03-23 04:58:42 +00004031- Bug #1683368: The object.__init__() and object.__new__() methods are
4032 now stricter in rejecting excess arguments. The only time when
4033 either allows excess arguments is when it is not overridden and the
4034 other one is. For backwards compatibility, when both are
4035 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004036 warning later). Also, type.__init__() insists on the same signature
4037 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004038
Georg Brandl3ee81df2008-05-17 18:14:43 +00004039- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4040 object to complex using its __complex__() method before falling back
4041 to the __float__() method. Therefore, the functions in the cmath
4042 module now can operate on objects that define a __complex__()
4043 method.

4060
Georg Brandl7b9c5552007-03-12 14:30:05 +00004061- Bug #1678647: write a newline after printing an exception in any
4062 case, even when converting the value to a string failed.
4063
Georg Brandl871f1bc2007-03-12 13:17:36 +00004064- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004065 its argument, if it exists. If not, it will work like before. This
4066 allows customizing the output of dir() in the presence of a
4067 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00004068
Collin Winter276887b2007-03-12 16:11:39 +00004069- Patch #922167: Python no longer segfaults when faced with infinitely
4070 self-recursive reload() calls (as reported by bug #742342).

4076 parthensized forms. This means complex(repr(x)) now works instead of
4077 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004078
Georg Brandlaa2321b2007-03-07 00:40:28 +00004079- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004080 makes the filenames the warning module prints much more sensible
4081 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004082

Georg Brandl0fca97a2007-03-05 22:28:08 +00004094- Patch #1674228: when assigning a slice (old-style), check for the
4095 sq_ass_slice instead of the sq_slice slot.
4096
Georg Brandl3ee81df2008-05-17 18:14:43 +00004097- When printing an unraisable error, don't print exceptions. before

4725 accepted in TestSuite.addTest(). This should cause no
4726 incompatibility since it never made sense with ordinary subclasses
4727 -- the failure just occurred later, with a more cumbersome
4728 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005009- Issue #829951: In the smtplib module, SMTP.starttls() now complies
5010 with RFC 3207 and forgets any knowledge obtained from the server not
5011 obtained from the TLS negotiation itself. Patch contributed by Bill
5012 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00005013
Georg Brandl3ee81df2008-05-17 18:14:43 +00005014- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005015 that the SMTP.starttls() caller no longer needs to call ehlo()
5016 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00005017 does not claim to support starttls. Adds the
5018 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

5099 complex, tuple, list, dict, set, and frozenset. Formerly, it would
5100 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00005117 time so that opening a database previously created with the DB_DUP
5118 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5119 opens. Specifically: dictionary assignment to a DB object will
5120 replace all values for a given key when the database allows
5121 duplicate values. DB users should use DB.put(k, v) when they want
5122 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005123

5129 characters with ASCII value less than 32. Also, it correctly quotes
5130 dots only if they occur on a single line, as opposed to the previous
5131 behavior of quoting dots if they are the second character of any
5132 line.

5455-----
5456
Georg Brandl3ee81df2008-05-17 18:14:43 +00005457- Unified naming convention for free lists and their limits. All free
5458 lists in Object/ are named ``free_list``, the counter ``numfree``
5459 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
5460 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00005461
Georg Brandl3ee81df2008-05-17 18:14:43 +00005462- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5463 to ``PyTuple_SetItem``, it can be used to populate a brand new
5464 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00005465
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005466- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00005467
Georg Brandl3ee81df2008-05-17 18:14:43 +00005468- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
5469 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
5470 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005471
5472- Patch #1720595: add T_BOOL to the range of structmember types.
5473
5474- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
5475 ``PyFloat_GetInfo()`` to the float API.
5476
Georg Brandl3ee81df2008-05-17 18:14:43 +00005477- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5478 of w# format code incorrectly truncated the length to an int, even
5479 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5480 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005481
Georg Brandl3ee81df2008-05-17 18:14:43 +00005482- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
5483 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005484
Georg Brandl3ee81df2008-05-17 18:14:43 +00005485- PEP 3123: Provide forward compatibility with Python 3.0, while
5486 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
5487 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005488
Georg Brandl3ee81df2008-05-17 18:14:43 +00005489- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
5490 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005491
5492- Patch #1733960: Allow T_LONGLONG to accept ints.
5493
5494- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
5495
Christian Heimes000a0742008-01-03 22:16:32 +00005496- Added a new API function ``PyImport_ImportModuleNoBlock``.
5497
Georg Brandl6caad7d2008-01-26 14:19:22 +00005498- Bug #1637022: Prefix AST symbols with _Py_.
5499
5500- Fix some leftovers from the conversion from int to Py_ssize_t
5501 (relevant to strings and sequences of more than 2**31 items).
5502
5503- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5504 outside of pystate.c and should not be necessary.
5505
Georg Brandl3ee81df2008-05-17 18:14:43 +00005506- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5507 absolute imports. In earlier versions they might have used relative
5508 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005509
Georg Brandl3ee81df2008-05-17 18:14:43 +00005510- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5511 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005512
Georg Brandl3ee81df2008-05-17 18:14:43 +00005513- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
5514 macro so it can be used as an expression.

5519
Georg Brandl3ee81df2008-05-17 18:14:43 +00005520- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
5521 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
5522 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
5523 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00005524
Georg Brandl3ee81df2008-05-17 18:14:43 +00005525- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
5526 _CRT_NONSTDC_NO_DEPRECATE.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005538- Removed the macfs module. It had been deprecated since Python 2.5.
5539 This lead to the deprecation of macostools.touched() as it relied
5540 solely on macfs and was a no-op under OS X.
