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

Georg Brandlba83f822010-03-14 09:50:54 +0000250- Issue #7712: test_support gained a new ``temp_cwd`` context manager which is
251 now also used by regrtest to run all the tests in a temporary directory. The
252 original CWD is saved in ``test.test_support.SAVEDCWD``. Thanks to Florent
253 Xicluna who helped with the patch.

270 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +0000271 library would return a bogus result; on Solaris, it was possible to crash the
272 interpreter. Patch by Stefan Krah.

Georg Brandlba83f822010-03-14 09:50:54 +0000285- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
286 and add the additional members returned in an OSVERSIONINFOEX structure. The
287 new members are service_pack_major, service_pack_minor, suite_mask, and
288 product_type.

Georg Brandlba83f822010-03-14 09:50:54 +0000290- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
291 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
292 returning NULL. The macro now returns a statically allocated empty string
293 instead.

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

323
Georg Brandlba83f822010-03-14 09:50:54 +0000324- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">") in
325 XML processing instructions and comments. These raw characters are allowed
326 by the XML specification, and are necessary when outputting e.g. PHP code in
327 a processing instruction. Patch by Neil Muller.

Antoine Pitroud840e512010-02-04 20:20:18 +0000335- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +0000336 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +0000337 Also, raise ValueError rather than TypeError when an unknown TIPC address
338 type is specified. Patch by Brian Curtin.
339
Vinay Sajip28c382f2010-02-04 18:48:53 +0000340- logging: Implemented PEP 391.
341
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000342- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +0000343 file position when calling `truncate()`. It would previously change the file
344 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000345 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
346
Benjamin Petersone06f7112010-01-28 02:15:02 +0000347- UserDict is now a new-style class.
348
Georg Brandlba83f822010-03-14 09:50:54 +0000349- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
350 class used to represent files stored inside an archive. The new
351 implementation is significantly faster and can be wrapped in a
352 ``io.BufferedReader`` object for more speedups. It also solves an issue
353 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
354 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +0000361- Issue #7773: Fix an UnboundLocalError in ``platform.linux_distribution()``
362 when the release file is empty.
Benjamin Petersona43f34c2010-01-25 03:31:13 +0000363
Georg Brandlba83f822010-03-14 09:50:54 +0000364- Issue #7748: Since unicode values are supported for some metadata options in
365 Distutils, the DistributionMetadata get_* methods will now return an utf-8
366 encoded string for them. This ensures that the upload and register commands
367 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +0000369- Issue #1670765: Prevent ``email.generator.Generator`` from re-wrapping
R. David Murrayed44dfa2010-01-16 05:15:17 +0000370 headers in multipart/signed MIME parts, which fixes one of the sources of

441Core and Builtins
442-----------------
443
Georg Brandlba83f822010-03-14 09:50:54 +0000444- The ``__complex__()`` method is now looked up on the class of instances to
445 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +0000446
Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000447- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
448 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
449
Mark Dickinson1b34d252010-01-01 17:27:30 +0000450- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000451 DeprecationWarning when passed a float argument where an integer was expected.
452 These functions and methods now raise TypeError instead. The majority of the
453 effects of this change are in the extension modules, but some core functions
454 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
455 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +0000468- Issue #1811: Improve accuracy and cross-platform consistency for true division
469 of integers: the result of a/b is now correctly rounded for ints a and b (at
470 least on IEEE 754 platforms), and in particular does not depend on the
471 internal representation of a long.

479
Georg Brandlba83f822010-03-14 09:50:54 +0000480 These executables now work properly with the arch(1) command: ``arch -ppc
481 python`` will start a universal binary version of python in PPC mode (unlike
482 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +0000638- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
639 decimal string that's guaranteed to round back to x under correct rounding
640 (with round-half-to-even rounding mode). Previously it gave a string based on
641 rounding x to 17 decimal digits. repr(x) for a complex number behaves
642 similarly. On platforms where the correctly-rounded strtod and dtoa code is
643 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000644
Georg Brandlba83f822010-03-14 09:50:54 +0000645- Issue #7117: On almost all platforms: float-to-string and string-to-float
646 conversions within Python are now correctly rounded. Places these conversions
647 occur include: str for floats and complex numbers; the float and complex
648 constructors; old-style and new-style numeric formatting; serialization and
649 deserialization of floats and complex numbers using marshal, pickle and json;
650 parsing of float and imaginary literals in Python code; Decimal-to-float
651 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000652
Georg Brandlba83f822010-03-14 09:50:54 +0000653 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
654 providing correctly-rounded strtod and dtoa C functions. This code is
655 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
656 the C compiler. There may be a small number of platforms on which correct
657 operation of this code cannot be guaranteed, so the code is not used: notably,
658 this applies to platforms where the C double format is not IEEE 754 binary64,
659 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
660 and Python's configure script is unable to determine how to change the FPU
661 precision. On these platforms conversions use the platform strtod and dtoa,
662 as before.

Georg Brandlba83f822010-03-14 09:50:54 +0000664- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
665 uses the correctly-rounded string <-> float conversions described above (when
666 available), and so produces correctly rounded results that will display nicely
667 under the float repr. There are two related small changes: (1) round now
668 accepts any class with an ``__index__()`` method for its second argument (but
669 no longer accepts floats for the second argument), and (2) an excessively
670 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
671 raises an exception.

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

Georg Brandlba83f822010-03-14 09:50:54 +00001007- Issue #4445: Replace ``sizeof(PyStringObject)`` with
1008 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
1009 instances. On a typical machine this saves 3 bytes of memory (on average) per

1021
Georg Brandlba83f822010-03-14 09:50:54 +00001022- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
1023 file objects with closefd=False. The file descriptor is still kept open but
1024 the file object behaves like a closed file. The ``FileIO`` object also got a
1025 new readonly attribute ``closefd``.

1044
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00001045- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00001046 because it is a reserved word in 3.x.

Georg Brandlba83f822010-03-14 09:50:54 +00001048- On windows, ``os.chdir()`` given unicode was not working if
1049 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
1050 this code path is really executed because I cannot move to such directory on
1051 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00001053- Issue #4069: When ``set.remove(element)`` is used with a set element, the
1054 element is temporarily replaced with an equivalent frozenset. But the
1055 eventual KeyError would always report the empty ``frozenset()`` as the missing
1056 key. Now it correctly refers to the initial element.

1075
Walter Dörwalded960ac2009-05-03 22:36:33 +00001076- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
1077 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1078 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1079 of using the replace error handler in PyUnicode_DecodeUTF8().
1080
Walter Dörwald726ba8e2009-05-06 14:32:35 +00001081- Issue #3739: The unicode-internal encoder now reports the number of characters

1083
Georg Brandlba83f822010-03-14 09:50:54 +00001084- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
1085 allocator will be automatically disabled when running under Valgrind. This
1086 gives improved memory leak detection when running under Valgrind, while taking
1087 advantage of pymalloc at other times.

2254 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
2255 neither __int__ nor __long__, TypeError used to be raised (with a

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002452- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2453
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002454- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2455 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2456 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2457 ``printf`` function, whereas PyString_FromFormat has an independent
2458 implementation and uses "%zd" on all platforms for size_t values.
2459 This makes a difference on win64, where ``printf`` needs "%Id" to display
2460 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00002462- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

2466 object; previously an int would be returned for small values. the __long__
2467 method is allowed to return either an int or a long, but the behaviour of
2468 float objects should not change to respect backward compatibility.

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002470- Issue #3751: str.rpartition would perform a left-partition when called with
2471 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +00002476 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002477 was correctly parsed but parsing of subsequent arguments failed.
2478
Vinay Sajip35e3b032008-09-01 14:33:59 +00002479- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002480 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2481 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2482 when given a tuple of classes as second argument, were looking up
2483 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2484 type object.
2485
Neal Norwitz18aa3882008-08-24 05:04:52 +00002486- Fix crashes on memory allocation failure found with failmalloc.

2629-----------------
2630
Guido van Rossumf8402962008-08-20 15:01:50 +00002631- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2632 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2633 extensions do not automatically benefit from the class attribute
2634 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2635 to their tp_flags field if they care. This is a backwards
2636 compatibility feature; in 3.0, all types will use the cache by
2637 default.
2638
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002639- Keyword arguments can now follow starred arguments. (``f(a, *args,
2640 keyword=23)`` is now valid syntax.)
2641
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002642- ctypes function pointers that are COM methods have a boolean True

Georg Brandl1e13ea92008-08-11 09:07:59 +00002649- Issue #3537: Fix an assertion failure when an empty but presized dict
2650 object was stored in the freelist.
2651
Mark Dickinsonb6467572008-08-04 21:30:09 +00002652- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2653 ValueError consistently across platforms.
2654
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002655- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2656 (64bit Unix, for example), unichr() would truncate its argument and return
2657 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2658
Neal Norwitze7d8be82008-07-31 17:17:14 +00002659- Apply security patches from Apple.
2660
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002661- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2662 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2663
Antoine Pitrou92f82162008-07-25 22:22:08 +00002664- Issue #1819: function calls with several named parameters are now on
2665 average 35% faster (as measured by pybench).
2666
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002667- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2668 the python debugger steps into a class statement: the free variables (local
2669 variables defined in an outer scope) would be deleted from the outer scope.
2670
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002671- Issue #2620: Overflow checking when allocating or reallocating memory
2672 was not always being done properly in some python types and extension
2673 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2674 all been updated to perform better checks and places in the code that
2675 would previously leak memory on the error path when such an allocation
2676 failed have been fixed.

2685
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002686- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2687 version reported by these tools does not necessarily follow the python
2688 version numbering scheme, so the module is less strict when parsing it.
2689
Nick Coghlanf70385a2008-08-18 12:42:46 +00002690- Issue #2235: Added Py3k warnings for types which will become unhashable
2691 under the stricter __hash__ inheritance rules in 3.0. Several types
2692 which did not meet the rules for hash invariants and were already
2693 unhashable in 3.0 have now been explicitly flagged as unhashable in
2694 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2695 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2696
Brett Cannon88f801d2008-08-18 00:46:22 +00002697- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

Brett Cannonbf3157b2008-08-14 05:00:03 +00002728- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2729 since mimetools itself is deprecated. Because modules are cached, all
2730 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2731
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002732- Issue #3134: shutil referenced undefined WindowsError symbol.

2744 to _sre.compile() will now be rejected. This should not affect anybody
2745 since the re.compile() function never generates invalid re-bytecode.

Skip Montanaroa032bf42008-08-08 22:52:51 +00002747- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2748 upon first access it can be automatically initialized from the csv file if
2749 it wasn't initialized during instantiation.
2750
Brett Cannon3aa2a492008-08-06 22:28:09 +00002751- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2752 the reload() built-in has been removed.
2753
Brett Cannon7e30b672008-08-04 21:52:25 +00002754- Changed code in the following modules/packages to remove warnings raised

2763 raised an AttributeError.
2764
Benjamin Peterson01a24322008-07-28 23:35:27 +00002765- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002766 asking for a specific length. This problem only affected files opened
2767 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002768

2791
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002792- Issue #3394: zipfile.writestr sets external attributes when passed a
2793 file name rather than a ZipInfo instance, so files are extracted with
2794 mode 0600 rather than 000 under Unix.
2795
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002796- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2797 argument in python 2.5, this broke code that subclassed Popen to include its

Nick Coghlan6e8fef02008-08-18 13:14:22 +00002808- Issue #2235: the C API function PyObject_HashNotImplemented and its
2809 interaction with the tp_hash slot (added in 2.6b2) are now documented
2810
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002811- Issue #643841: The language reference now provides more detailed
2812 coverage of the lookup process for special methods. The disclaimers
2813 regarding lack of coverage of new-style classes have also been
2814 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00002822Core and Builtins
2823-----------------
2824
Georg Brandl3e483f62008-07-16 22:57:41 +00002825- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2826 its methods now allow for items objects that can be converted to
2827 an integer using operator.index().
2828
Mark Dickinson64b7e502008-07-16 09:40:03 +00002829- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2830 produced a ValueError instead of giving the correct float.
2831
Eric Smitha5fa5a22008-07-16 00:11:49 +00002832- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2833 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2834
Mark Dickinson7103aa42008-07-15 19:08:33 +00002835- Issue #3008: the float type has a new instance method 'float.hex'
2836 and a new class method 'float.fromhex' to convert floating-point
2837 numbers to and from hexadecimal strings, respectively.
2838
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002839- Issue #2235: __hash__ is once again inherited by default. To allow
2840 collections.Hashable to remain meaningful in the presence of the
2841 default hash implementation (object.__hash__), it is now possible
2842 to explicit block inheritance of hash by setting __hash__=None at
2843 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2844 level.
2845
Nick Coghlanb028f502008-07-13 14:52:36 +00002846- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2847 the parent module cannot be found while performing an absolute import.
2848 This means that an incorrectly defined __package__ attribute will
2849 now only prevent relative imports in that module rather than causing
2850 all imports from that module to fail.
2851
Nick Coghlan14ff9942008-07-08 14:21:42 +00002852- Issue #2517: Allow unicode messages in Exceptions again by correctly
2853 bypassing the instance dictionary when looking up __unicode__ on
2854 new-style classes.
2855
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002856- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2857 set to a custom object whose write() method happens to install
2858 another file in sys.stdout.
2859
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002860- Issue #3088: Corrected a race condition in classes derived from
2861 threading.local: the first member set by a thread could be saved in
2862 another thread's dictionary.
2863
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002864- Issue #3004: Minor change to slice.indices(): the start and stop
2865 arguments are now treated identically, making the behaviour easier
2866 to describe and understand. For example, slice(None, -10,
2867 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2868 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2869 10, -1).
2870
Georg Brandl278fc502008-07-19 12:46:12 +00002871- Issue #3219: Calling a function with repeated keyword arguments,
2872 f(a=2, a=23), would not cause a syntax error. This was a regression
2873 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002874
Georg Brandl278fc502008-07-19 12:46:12 +00002875- Issue #2862: Make int and float freelist management consistent with
2876 other freelists. Changes their CompactFreeList apis into
2877 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00002878

2880-------
2881
Thomas Heller57adf222008-08-14 19:10:48 +00002882- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2883 api functions without holding the GIL, which could lead to a fatal
2884 error when they failed.
2885
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002886- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

2895 ForkingPickler.register() to resolve conflict with ctypes.
2896
Vinay Sajip51e65192008-07-18 09:01:10 +00002897- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Thomas Heller880f5292008-07-15 19:39:38 +00002899- Issue #3313: Fixed a crash when a failed dlopen() call does not set
2900 a valid dlerror() message.
2901
Thomas Heller2bad6572008-07-15 17:19:50 +00002902- Issue #3258: Fixed a crash when a ctypes POINTER type to an
2903 incomplete structure was created.
2904
Brett Cannon3d0b9f02008-07-13 01:15:07 +00002905- Issue #3339: dummy_thread.acquire() should not return None.

Raymond Hettingerb01713e2008-07-10 14:34:57 +00002907- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
2908
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002909- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00002910
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002911- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2912 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002913 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002914 content-length. The problem had been corrected in the 2.4 branch, but never
2915 merged into trunk.
2916
Georg Brandle78fbcc2008-07-05 10:13:36 +00002917- Issue #2663: add filtering capability to shutil.copytree().

2923- Issue #1746: Correct handling of zipfile archive comments (previously
2924 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00002925 Zip files with archives by setting the 'comment' attribute of a ZipFile.

3322 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00003323 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003324
3325 This is controlled by the configure argument ``--with-universal-archs``:
3326
3327 - ``--with-universal-archs=all``: install 4-way universal
3328
3329 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3330
3331 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3332
3333 This option should be used in combination with ``--enable-universalsdk=``.
3334
3335 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 +00003385- Issue #1631171: Re-implement the 'warnings' module in C (the
3386 original Python code has been kept as backup). This will allow for
3387 using the 'warning's machinery in such places as the parser where
3388 use of pure Python code is not possible. Both the ``showarning()``
3389 and ``formatwarning()`` gain an optional 'line' argument which is
3390 not called by default for backwards-compatibility reasons. Setting
3391 ``warnings.showwarning()`` to an implementation that lacks support
3392 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00003417- The getpass module has been improved on Unix. It now uses /dev/tty
3418 by default and uses stderr instead of stdout. A GetPassWarning is
3419 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003455- Issue #2550: The approach used by client/server code for obtaining
3456 ports to listen on in network-oriented tests has been refined in an
3457 effort to facilitate running multiple instances of the entire
3458 regression test suite in parallel without issue.
3459 test_support.bind_port() has been fixed such that it will always
3460 return a unique port -- which wasn't always the case with the
3461 previous implementation, especially if socket options had been set
3462 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3463 new implementation of bind_port() will actually raise an exception
3464 if it is passed an AF_INET/SOCK_STREAM socket with either the
3465 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3466 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3467 the socket it's been passed. This currently only applies to
3468 Windows. This option prevents any other sockets from binding to the
3469 host/port we've bound to, thus removing the possibility of the
3470 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3471 when a second SOCK_STREAM socket binds and accepts to a host/port
3472 that's already been bound by another socket. The optional preferred
3473 port parameter to bind_port() has been removed. Under no
3474 circumstances should tests be hard coding ports!
3475
3476 test_support.find_unused_port() has also been introduced, which will
3477 pass a temporary socket object to bind_port() in order to obtain an
3478 unused port. The temporary socket object is then closed and
3479 deleted, and the port is returned. This method should only be used
3480 for obtaining an unused port in order to pass to an external program
3481 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3482 a parameter to a server-oriented class that doesn't give you direct
3483 access to the underlying socket used.
3484
3485 Finally, test_support.HOST has been introduced, which should be used
3486 for the host argument of any relevant socket calls (i.e. bind and
3487 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003488

3761Core and builtins
3762-----------------
3763
Fred Drakea8ee94b2008-03-01 02:45:07 +00003764- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003765 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00003766
Georg Brandlad61bc82008-02-23 15:11:18 +00003767- Issue #2067: file.__exit__() now calls subclasses' close() method.
3768
3769- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003770
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003771- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003772 issue 215555 for a discussion.
3773
Eric Smitha73fbe72008-02-23 03:09:44 +00003774- Added the future_builtins module, which contains hex() and oct().
3775 These are the PEP 3127 version of these functions, designed to be
3776 compatible with the hex() and oct() builtins from Python 3.0. They
3777 differ slightly in their output formats from the existing, unchanged
3778 Python 2.6 builtins. The expected usage of the future_builtins
3779 module is:
3780 from future_builtins import hex, oct
3781
Eric Smith7ef40bf2008-02-20 23:34:22 +00003782- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3783 exponents for exponents with absolute value < 100. Follows C99
3784 standard. This is a change on Windows, which would use 3 digits.
3785 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3786 so that any alterations it does to the resulting string will be
3787 available in stringlib/formatter.h (for float.__format__).
3788
Eric Smith5a3c1352008-02-19 13:21:56 +00003789- Implemented PEP 3101, Advanced String Formatting. This adds a new
3790 builtin format(); a format() method for str and unicode; a
3791 __format__() method to object, str, unicode, int, long, float, and
3792 datetime; the class string.Formatter; and the C API
3793 PyObject_Format().
3794
Georg Brandl3ee81df2008-05-17 18:14:43 +00003795- Fixed several potential crashes, all caused by specially crafted
3796 __del__ methods exploiting objects in temporarily inconsistent
3797 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003798
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003799- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003800 prevent a possible crash: an Abstract Base Class would try to access
3801 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003802
Georg Brandl3ee81df2008-05-17 18:14:43 +00003803- Fixed repr() and str() of complex numbers with infinity or nan as
3804 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003805
Georg Brandl3ee81df2008-05-17 18:14:43 +00003806- Clear all free lists during a gc.collect() of the highest generation
3807 in order to allow pymalloc to free more arenas. Python may give back
3808 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003809
Georg Brandl3ee81df2008-05-17 18:14:43 +00003810- Issue #2045: Fix an infinite recursion triggered when printing a
3811 subclass of collections.defaultdict, if its default_factory is set
3812 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003813
Christian Heimesf75dbef2008-02-08 00:11:31 +00003814- Fixed a minor memory leak in dictobject.c. The content of the free
3815 list was not freed on interpreter shutdown.
3816
Georg Brandl21e99f42010-03-07 15:23:59 +00003817- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003818 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003819
Georg Brandl3ee81df2008-05-17 18:14:43 +00003820- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3821 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003822 to compact the internal free lists of pre-allocted ints and floats.
3823
Georg Brandl3ee81df2008-05-17 18:14:43 +00003824- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3825 calls. Python expected the return type int but the fork familie
3826 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003827
Georg Brandl3ee81df2008-05-17 18:14:43 +00003828- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3829 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003830
Georg Brandl3ee81df2008-05-17 18:14:43 +00003831- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3832 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003833
Georg Brandl3ee81df2008-05-17 18:14:43 +00003834- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3835 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003836
Georg Brandl3ee81df2008-05-17 18:14:43 +00003837- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3838 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003839
Georg Brandl3ee81df2008-05-17 18:14:43 +00003840- Patch #1473257: generator objects gain a gi_code attribute. This is
3841 the same object as the func_code attribute of the function that
3842 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003843
Georg Brandl3ee81df2008-05-17 18:14:43 +00003844- Issue #1920: "while 0" statements were completely removed by the
3845 compiler, even in the presence of an "else" clause, which is
3846 supposed to be run when the condition is false. Now the compiler
3847 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003848
Guido van Rossumeead05f2008-01-24 18:21:02 +00003849- A few crashers fixed: weakref_in_del.py (issue #1377858);
3850 loosing_dict_ref.py (issue #1303614, test67.py);
3851 borrowed_ref_[34].py (not in tracker).
3852
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003853- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003854 suppressed while an extension is loaded by calling SetErrorMode in
3855 dynload_win.c. The error is still reported properly.
3856
Georg Brandl3ee81df2008-05-17 18:14:43 +00003857- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003858 several extension methods and modules do not work without unicode
3859 support.
3860
Georg Brandl26543b12008-01-21 18:36:51 +00003861- Issue #1882: when compiling code from a string, encoding cookies in the
3862 second line of code were not always recognized correctly.
3863
Georg Brandl14404b62008-01-19 19:27:05 +00003864- Issue #1679: "0x" was taken as a valid integer literal.
3865
Georg Brandl6caad7d2008-01-26 14:19:22 +00003866- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003867 added.
3868
Christian Heimesc94e2b52008-01-14 04:13:37 +00003869- sys.float_info / PyFloat_GetInfo: The floating point information
3870 object was converted from a dict to a specialized structseq object.
3871
Georg Brandl3ee81df2008-05-17 18:14:43 +00003872- Patch #1816: Added sys.flags structseq. It exposes the status of
3873 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003874
Georg Brandl3ee81df2008-05-17 18:14:43 +00003875- Objects/structseq.c: Implemented new structseq representation. The
3876 patch makes structseqs (e.g. the return value of os.stat) more
3877 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003878
Georg Brandl3ee81df2008-05-17 18:14:43 +00003879- Patch #1700288: added a type attribute cache that caches method
3880 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003881
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003882- Bug #1776: __import__() no longer accepts filenames on any platform.
3883 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003884
Georg Brandlaed6c662008-01-07 17:25:53 +00003885- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3886
Georg Brandl3ee81df2008-05-17 18:14:43 +00003887- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3888 envvar and sys.dont_write_bytecode attribute. All these can be set
3889 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003890
Georg Brandl3ee81df2008-05-17 18:14:43 +00003891- Improve some exception messages when Windows fails to load an
3892 extension module. Now we get for example '%1 is not a valid Win32
3893 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003894
Georg Brandl3ee81df2008-05-17 18:14:43 +00003895- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003897- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3898 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003899
Christian Heimes0a8143f2007-12-18 23:22:54 +00003900- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003901 and INF. float("nan"), float("inf") and float("-inf") now work on
3902 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003903
Georg Brandl3ee81df2008-05-17 18:14:43 +00003904- Compiler now generates simpler and faster code for dictionary
3905 literals. The oparg for BUILD_MAP now indicates an estimated
3906 dictionary size. There is a new opcode, STORE_MAP, for adding
3907 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00003908
Georg Brandl3ee81df2008-05-17 18:14:43 +00003909- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003914- Issue #1538: Avoid copying string in split/rsplit if the split char
3915 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00003916
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00003917- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00003918 SystemError.
3919
Nick Coghlanef01d822007-12-03 12:55:17 +00003920- PEP 366: Allow explicit relative imports when executing modules
3921 inside packages with the -m switch via a new module level
3922 __package__ attribute.
3923
Georg Brandl3ee81df2008-05-17 18:14:43 +00003924- Issue #1402: Fix a crash on exit, when another thread is still
3925 running, and if the deallocation of its frames somehow calls the
3926 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00003927

3937 file can now be directly executed by passing their name to the
3938 interpreter. The directory/zipfile is automatically inserted as the
3939 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003940
Georg Brandl3ee81df2008-05-17 18:14:43 +00003941- Issue #1265: Fix a problem with sys.settrace, if the tracing
3942 function uses a generator expression when at the same time the
3943 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003944
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003945- sets and frozensets now have an isdisjoint() method.
3946
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003947- optimize the performance of builtin.sum().
3948
Neal Norwitz44f326e2007-10-05 05:29:17 +00003949- Fix warnings found by the new version of the Coverity checker.
3950
Georg Brandl21e99f42010-03-07 15:23:59 +00003951- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003952 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3953 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003954
Georg Brandl3ee81df2008-05-17 18:14:43 +00003955- Issue #1686386: Tuple's tp_repr did not take into account the
3956 possibility of having a self-referential tuple, which is possible
3957 from C code. Nor did object's tp_str consider that a type's tp_str
3958 could do something that could lead to an inifinite recursion.
3959 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3960 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003961
Georg Brandl3ee81df2008-05-17 18:14:43 +00003962- Issue #1164: It was possible to trigger deadlock when using the
3963 'print' statement to write to a file since the GIL was not released
3964 as needed. Now PyObject_Print() does the right thing along with
3965 various tp_print implementations of the built-in types and those in
3966 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003967
Georg Brandl3ee81df2008-05-17 18:14:43 +00003968- Issue #1147: Exceptions were directly allowing string exceptions in
3969 their throw() method even though string exceptions no longer
3970 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003971

Brett Cannon1e534b52007-09-07 04:18:30 +00003975- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003976 PyObject_Call() never calling back out to Python code to trigger
3977 recursion depth updates/checks. Required the creation of a static
3978 RuntimeError instance in case normalizing an exception put the
3979 recursion check value past its limit. Fixes crashers
3980 infinite_rec_(1|2|4|5).py.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003996 __*__ attributes. (Some already existed, e.g., __doc__ and
3997 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003998
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003999- Add -3 option to the interpreter to warn about features that are

Georg Brandl3ee81df2008-05-17 18:14:43 +00004006 "except E as target:". This is to provide forwards compatibility
4007 with Python 3.0.

Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004015 setting a plain string, ie don't expand to single letter identifiers.
4016
Raymond Hettinger13936692007-04-11 18:40:58 +00004017- Request #1191699: Slices can now be pickled.

4027
Guido van Rossum143b5642007-03-23 04:58:42 +00004028- Bug #1683368: The object.__init__() and object.__new__() methods are
4029 now stricter in rejecting excess arguments. The only time when
4030 either allows excess arguments is when it is not overridden and the
4031 other one is. For backwards compatibility, when both are
4032 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004033 warning later). Also, type.__init__() insists on the same signature
4034 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004035
Georg Brandl3ee81df2008-05-17 18:14:43 +00004036- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4037 object to complex using its __complex__() method before falling back
4038 to the __float__() method. Therefore, the functions in the cmath
4039 module now can operate on objects that define a __complex__()
4040 method.

4057
Georg Brandl7b9c5552007-03-12 14:30:05 +00004058- Bug #1678647: write a newline after printing an exception in any
4059 case, even when converting the value to a string failed.
4060
Georg Brandl871f1bc2007-03-12 13:17:36 +00004061- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004062 its argument, if it exists. If not, it will work like before. This
4063 allows customizing the output of dir() in the presence of a
4064 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00004065
Collin Winter276887b2007-03-12 16:11:39 +00004066- Patch #922167: Python no longer segfaults when faced with infinitely
4067 self-recursive reload() calls (as reported by bug #742342).

4073 parthensized forms. This means complex(repr(x)) now works instead of
4074 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004075
Georg Brandlaa2321b2007-03-07 00:40:28 +00004076- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004077 makes the filenames the warning module prints much more sensible
4078 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004079

Georg Brandl0fca97a2007-03-05 22:28:08 +00004091- Patch #1674228: when assigning a slice (old-style), check for the
4092 sq_ass_slice instead of the sq_slice slot.
4093
Georg Brandl3ee81df2008-05-17 18:14:43 +00004094- When printing an unraisable error, don't print exceptions. before

4719
Georg Brandl3ee81df2008-05-17 18:14:43 +00004720- unittest now verifies more of its assumptions. In particular,

4722 accepted in TestSuite.addTest(). This should cause no
4723 incompatibility since it never made sense with ordinary subclasses
4724 -- the failure just occurred later, with a more cumbersome
4725 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005006- Issue #829951: In the smtplib module, SMTP.starttls() now complies
5007 with RFC 3207 and forgets any knowledge obtained from the server not
5008 obtained from the TLS negotiation itself. Patch contributed by Bill
5009 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00005010
Georg Brandl3ee81df2008-05-17 18:14:43 +00005011- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005012 that the SMTP.starttls() caller no longer needs to call ehlo()
5013 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00005014 does not claim to support starttls. Adds the
5015 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +00005114 time so that opening a database previously created with the DB_DUP
5115 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5116 opens. Specifically: dictionary assignment to a DB object will
5117 replace all values for a given key when the database allows
5118 duplicate values. DB users should use DB.put(k, v) when they want
5119 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005120

5126 characters with ASCII value less than 32. Also, it correctly quotes
5127 dots only if they occur on a single line, as opposed to the previous
5128 behavior of quoting dots if they are the second character of any
5129 line.

5452-----
5453
Georg Brandl3ee81df2008-05-17 18:14:43 +00005454- Unified naming convention for free lists and their limits. All free
5455 lists in Object/ are named ``free_list``, the counter ``numfree``
5456 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
5457 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00005458
Georg Brandl3ee81df2008-05-17 18:14:43 +00005459- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5460 to ``PyTuple_SetItem``, it can be used to populate a brand new
5461 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00005462
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005463- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00005464
Georg Brandl3ee81df2008-05-17 18:14:43 +00005465- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
5466 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
5467 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005468
5469- Patch #1720595: add T_BOOL to the range of structmember types.
5470
5471- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
5472 ``PyFloat_GetInfo()`` to the float API.
5473
Georg Brandl3ee81df2008-05-17 18:14:43 +00005474- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5475 of w# format code incorrectly truncated the length to an int, even
5476 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5477 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005478
Georg Brandl3ee81df2008-05-17 18:14:43 +00005479- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
5480 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005481
Georg Brandl3ee81df2008-05-17 18:14:43 +00005482- PEP 3123: Provide forward compatibility with Python 3.0, while
5483 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
5484 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005485
Georg Brandl3ee81df2008-05-17 18:14:43 +00005486- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
5487 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005488
5489- Patch #1733960: Allow T_LONGLONG to accept ints.
5490
5491- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
5492
Christian Heimes000a0742008-01-03 22:16:32 +00005493- Added a new API function ``PyImport_ImportModuleNoBlock``.
5494
Georg Brandl6caad7d2008-01-26 14:19:22 +00005495- Bug #1637022: Prefix AST symbols with _Py_.
5496
5497- Fix some leftovers from the conversion from int to Py_ssize_t
5498 (relevant to strings and sequences of more than 2**31 items).
5499
5500- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5501 outside of pystate.c and should not be necessary.
5502
Georg Brandl3ee81df2008-05-17 18:14:43 +00005503- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5504 absolute imports. In earlier versions they might have used relative
5505 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005506
Georg Brandl3ee81df2008-05-17 18:14:43 +00005507- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5508 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005509
Georg Brandl3ee81df2008-05-17 18:14:43 +00005510- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
5511 macro so it can be used as an expression.

5516
Georg Brandl3ee81df2008-05-17 18:14:43 +00005517- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
5518 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
5519 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
5520 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00005521
Georg Brandl3ee81df2008-05-17 18:14:43 +00005522- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
5523 _CRT_NONSTDC_NO_DEPRECATE.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005535- Removed the macfs module. It had been deprecated since Python 2.5.
5536 This lead to the deprecation of macostools.touched() as it relied
5537 solely on macfs and was a no-op under OS X.
