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

261 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +0000262 library would return a bogus result; on Solaris, it was possible to crash the
263 interpreter. Patch by Stefan Krah.

Georg Brandlba83f822010-03-14 09:50:54 +0000276- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
277 and add the additional members returned in an OSVERSIONINFOEX structure. The
278 new members are service_pack_major, service_pack_minor, suite_mask, and
279 product_type.

Georg Brandlba83f822010-03-14 09:50:54 +0000281- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
282 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
283 returning NULL. The macro now returns a statically allocated empty string
284 instead.

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

313 interpreter shutdown.
314
Georg Brandlba83f822010-03-14 09:50:54 +0000315- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">") in
316 XML processing instructions and comments. These raw characters are allowed
317 by the XML specification, and are necessary when outputting e.g. PHP code in
318 a processing instruction. Patch by Neil Muller.

Antoine Pitroud840e512010-02-04 20:20:18 +0000326- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +0000327 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +0000328 Also, raise ValueError rather than TypeError when an unknown TIPC address
329 type is specified. Patch by Brian Curtin.
330
Vinay Sajip28c382f2010-02-04 18:48:53 +0000331- logging: Implemented PEP 391.
332
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000333- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +0000334 file position when calling `truncate()`. It would previously change the file
335 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000336 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
337
Benjamin Petersone06f7112010-01-28 02:15:02 +0000338- UserDict is now a new-style class.
339
Georg Brandlba83f822010-03-14 09:50:54 +0000340- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
341 class used to represent files stored inside an archive. The new
342 implementation is significantly faster and can be wrapped in a
343 ``io.BufferedReader`` object for more speedups. It also solves an issue
344 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
345 Patch by Nir Aides.
Antoine Pitrou94c33eb2010-01-27 20:59:50 +0000346
Benjamin Peterson2deb5c72010-01-27 02:16:42 +0000347- Issue #7792: Registering non-classes to ABCs raised an obscure error.

Georg Brandlba83f822010-03-14 09:50:54 +0000352- Issue #7773: Fix an UnboundLocalError in ``platform.linux_distribution()``
353 when the release file is empty.
Benjamin Petersona43f34c2010-01-25 03:31:13 +0000354
Georg Brandlba83f822010-03-14 09:50:54 +0000355- Issue #7748: Since unicode values are supported for some metadata options in
356 Distutils, the DistributionMetadata get_* methods will now return an utf-8
357 encoded string for them. This ensures that the upload and register commands
358 send the correct values to PyPI without any error.
Tarek Ziadéf14c7fc2010-01-24 00:33:32 +0000359
Georg Brandlba83f822010-03-14 09:50:54 +0000360- Issue #1670765: Prevent ``email.generator.Generator`` from re-wrapping
R. David Murrayed44dfa2010-01-16 05:15:17 +0000361 headers in multipart/signed MIME parts, which fixes one of the sources of

432Core and Builtins
433-----------------
434
Georg Brandlba83f822010-03-14 09:50:54 +0000435- The ``__complex__()`` method is now looked up on the class of instances to
436 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +0000437
Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000438- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
439 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
440
Mark Dickinson1b34d252010-01-01 17:27:30 +0000441- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000442 DeprecationWarning when passed a float argument where an integer was expected.
443 These functions and methods now raise TypeError instead. The majority of the
444 effects of this change are in the extension modules, but some core functions
445 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
446 and many unicode/str methods.

458
Georg Brandlba83f822010-03-14 09:50:54 +0000459- Issue #1811: Improve accuracy and cross-platform consistency for true division
460 of integers: the result of a/b is now correctly rounded for ints a and b (at
461 least on IEEE 754 platforms), and in particular does not depend on the
462 internal representation of a long.

Ronald Oussoren92919a62009-12-24 13:30:58 +0000469 executables on OSX.
470
Georg Brandlba83f822010-03-14 09:50:54 +0000471 These executables now work properly with the arch(1) command: ``arch -ppc
472 python`` will start a universal binary version of python in PPC mode (unlike
473 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +0000474

Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000628
Georg Brandlba83f822010-03-14 09:50:54 +0000629- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
630 decimal string that's guaranteed to round back to x under correct rounding
631 (with round-half-to-even rounding mode). Previously it gave a string based on
632 rounding x to 17 decimal digits. repr(x) for a complex number behaves
633 similarly. On platforms where the correctly-rounded strtod and dtoa code is
634 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000635
Georg Brandlba83f822010-03-14 09:50:54 +0000636- Issue #7117: On almost all platforms: float-to-string and string-to-float
637 conversions within Python are now correctly rounded. Places these conversions
638 occur include: str for floats and complex numbers; the float and complex
639 constructors; old-style and new-style numeric formatting; serialization and
640 deserialization of floats and complex numbers using marshal, pickle and json;
641 parsing of float and imaginary literals in Python code; Decimal-to-float
642 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000643
Georg Brandlba83f822010-03-14 09:50:54 +0000644 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
645 providing correctly-rounded strtod and dtoa C functions. This code is
646 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
647 the C compiler. There may be a small number of platforms on which correct
648 operation of this code cannot be guaranteed, so the code is not used: notably,
649 this applies to platforms where the C double format is not IEEE 754 binary64,
650 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
651 and Python's configure script is unable to determine how to change the FPU
652 precision. On these platforms conversions use the platform strtod and dtoa,
653 as before.

Georg Brandlba83f822010-03-14 09:50:54 +0000655- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
656 uses the correctly-rounded string <-> float conversions described above (when
657 available), and so produces correctly rounded results that will display nicely
658 under the float repr. There are two related small changes: (1) round now
659 accepts any class with an ``__index__()`` method for its second argument (but
660 no longer accepts floats for the second argument), and (2) an excessively
661 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
662 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +0000804
Georg Brandlba83f822010-03-14 09:50:54 +0000805 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
806 (2) parsing of strings representing infinities and nans was locale aware; and
807 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +0000809- Issue #5920: For ``float.__format__()``, change the behavior with the empty
810 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
811 but with at least one decimal point and with a default precision
812 of 12. Previously, the behavior the same but with a default precision of 6.
813 This more closely matches ``str()``, and reduces surprises when adding
814 alignment flags to the empty presentation type. This also affects the new
815 complex.__format__ in the same way.
816
817- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

Georg Brandl6425a2f2008-12-28 11:54:53 +0000978- Issue #4759: None is now allowed as the first argument of
Georg Brandlba83f822010-03-14 09:50:54 +0000979 ``bytearray.translate()``. It was always allowed for ``bytes.translate()``.
Georg Brandl6425a2f2008-12-28 11:54:53 +0000980
Skip Montanarof205c132008-12-23 03:30:15 +0000981- Added test case to ensure attempts to read from a file opened for writing

Georg Brandlba83f822010-03-14 09:50:54 +0000998- Issue #4445: Replace ``sizeof(PyStringObject)`` with
999 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
1000 instances. On a typical machine this saves 3 bytes of memory (on average) per
1001 string allocation.

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00001003- Issue #3996: On Windows, the PyOS_CheckStack function would cause the

1005 instead of throwing a MemoryError.
1006
Georg Brandlba83f822010-03-14 09:50:54 +00001007- Issue #3689: The list reversed iterator now supports __length_hint__ instead

1012
Georg Brandlba83f822010-03-14 09:50:54 +00001013- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
1014 file objects with closefd=False. The file descriptor is still kept open but
1015 the file object behaves like a closed file. The ``FileIO`` object also got a
1016 new readonly attribute ``closefd``.

1034 __future__ import didn't work.
1035
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00001036- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00001037 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00001038
Georg Brandlba83f822010-03-14 09:50:54 +00001039- On windows, ``os.chdir()`` given unicode was not working if
1040 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
1041 this code path is really executed because I cannot move to such directory on
1042 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00001044- Issue #4069: When ``set.remove(element)`` is used with a set element, the
1045 element is temporarily replaced with an equivalent frozenset. But the
1046 eventual KeyError would always report the empty ``frozenset()`` as the missing
1047 key. Now it correctly refers to the initial element.

1066
Walter Dörwalded960ac2009-05-03 22:36:33 +00001067- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
1068 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1069 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1070 of using the replace error handler in PyUnicode_DecodeUTF8().
1071
Walter Dörwald726ba8e2009-05-06 14:32:35 +00001072- Issue #3739: The unicode-internal encoder now reports the number of characters

1074
Georg Brandlba83f822010-03-14 09:50:54 +00001075- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
1076 allocator will be automatically disabled when running under Valgrind. This
1077 gives improved memory leak detection when running under Valgrind, while taking
1078 advantage of pymalloc at other times.

2245 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
2246 neither __int__ nor __long__, TypeError used to be raised (with a

Georg Brandlba83f822010-03-14 09:50:54 +00002301 leak-chasing test runs give sensible results. The previous method of reaping

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002443- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2444
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002445- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2446 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2447 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2448 ``printf`` function, whereas PyString_FromFormat has an independent
2449 implementation and uses "%zd" on all platforms for size_t values.
2450 This makes a difference on win64, where ``printf`` needs "%Id" to display
2451 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00002453- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

2457 object; previously an int would be returned for small values. the __long__
2458 method is allowed to return either an int or a long, but the behaviour of
2459 float objects should not change to respect backward compatibility.
2460
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002461- Issue #3751: str.rpartition would perform a left-partition when called with
2462 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +00002467 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002468 was correctly parsed but parsing of subsequent arguments failed.
2469
Vinay Sajip35e3b032008-09-01 14:33:59 +00002470- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002471 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2472 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2473 when given a tuple of classes as second argument, were looking up
2474 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2475 type object.
2476
Neal Norwitz18aa3882008-08-24 05:04:52 +00002477- Fix crashes on memory allocation failure found with failmalloc.
2478
2479- Fix memory leaks found with valgrind and update suppressions file.

2620-----------------
2621
Guido van Rossumf8402962008-08-20 15:01:50 +00002622- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2623 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2624 extensions do not automatically benefit from the class attribute
2625 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2626 to their tp_flags field if they care. This is a backwards
2627 compatibility feature; in 3.0, all types will use the cache by
2628 default.
2629
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002630- Keyword arguments can now follow starred arguments. (``f(a, *args,

Mark Dickinsonb6467572008-08-04 21:30:09 +00002643- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2644 ValueError consistently across platforms.
2645
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002646- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2647 (64bit Unix, for example), unichr() would truncate its argument and return
2648 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2649
Neal Norwitze7d8be82008-07-31 17:17:14 +00002650- Apply security patches from Apple.
2651
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002652- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2653 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2654
Antoine Pitrou92f82162008-07-25 22:22:08 +00002655- Issue #1819: function calls with several named parameters are now on
2656 average 35% faster (as measured by pybench).
2657
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002658- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2659 the python debugger steps into a class statement: the free variables (local
2660 variables defined in an outer scope) would be deleted from the outer scope.
2661
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002662- Issue #2620: Overflow checking when allocating or reallocating memory
2663 was not always being done properly in some python types and extension
2664 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2665 all been updated to perform better checks and places in the code that
2666 would previously leak memory on the error path when such an allocation
2667 failed have been fixed.

2673
Benjamin Petersone977ad42008-08-20 01:42:01 +00002674- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2675 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2676
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002677- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2678 version reported by these tools does not necessarily follow the python
2679 version numbering scheme, so the module is less strict when parsing it.
2680
Nick Coghlanf70385a2008-08-18 12:42:46 +00002681- Issue #2235: Added Py3k warnings for types which will become unhashable
2682 under the stricter __hash__ inheritance rules in 3.0. Several types
2683 which did not meet the rules for hash invariants and were already
2684 unhashable in 3.0 have now been explicitly flagged as unhashable in
2685 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2686 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2687
Brett Cannon88f801d2008-08-18 00:46:22 +00002688- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2689 imported into the module but exposed as part of the module's API.
2690

2696
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002697- Issue #3575: Incremental decoder's decode function now takes bytearray
2698 by using 's*' instead of 't#'.
2699
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002700- Issue #2222: Fixed reference leak when occurred os.rename()

Facundo Batistaeb90b782008-08-16 14:44:07 +00002709- Issue #2776: fixed small issue when handling an URL with double slash
2710 after a 302 response in the case of not going through a proxy.
2711
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002712- Issue #2676: in the email package, content-type parsing was hanging on
2713 pathological input because of quadratic or exponential behaviour of a
2714 regular expression.
2715
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002716- Issue #3476: binary buffered reading through the new "io" library is now
2717 thread-safe.
2718
Brett Cannonbf3157b2008-08-14 05:00:03 +00002719- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2720 since mimetools itself is deprecated. Because modules are cached, all
2721 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2722
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002723- Issue #3134: shutil referenced undefined WindowsError symbol.

Robert Schuppenies14646332008-08-10 11:01:53 +00002725- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2726 menu entries were not deleted.
2727
Brett Cannon83e81842008-08-09 23:30:55 +00002728- Copied the implementation of reduce() to _functools.reduce() to have a
2729 version that did not raise a DeprecationWarning under -3.
2730
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002731- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2732 a MemoryError rather than silently stop the iteration.
2733
Guido van Rossum59ce9012008-08-09 14:55:34 +00002734- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2735 to _sre.compile() will now be rejected. This should not affect anybody
2736 since the re.compile() function never generates invalid re-bytecode.
2737
Skip Montanaroa032bf42008-08-08 22:52:51 +00002738- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2739 upon first access it can be automatically initialized from the csv file if
2740 it wasn't initialized during instantiation.
2741
Brett Cannon3aa2a492008-08-06 22:28:09 +00002742- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2743 the reload() built-in has been removed.
2744
Brett Cannon7e30b672008-08-04 21:52:25 +00002745- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002746 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

2754 raised an AttributeError.
2755
Benjamin Peterson01a24322008-07-28 23:35:27 +00002756- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002757 asking for a specific length. This problem only affected files opened
2758 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002759

2782
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002783- Issue #3394: zipfile.writestr sets external attributes when passed a
2784 file name rather than a ZipInfo instance, so files are extracted with
2785 mode 0600 rather than 000 under Unix.
2786
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002787- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2788 argument in python 2.5, this broke code that subclassed Popen to include its
2789 own poll method. Fixed my moving _deadstate to an _internal_poll method.

2797-------------
2798
Nick Coghlan6e8fef02008-08-18 13:14:22 +00002799- Issue #2235: the C API function PyObject_HashNotImplemented and its
2800 interaction with the tp_hash slot (added in 2.6b2) are now documented
2801
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002802- Issue #643841: The language reference now provides more detailed
2803 coverage of the lookup process for special methods. The disclaimers
2804 regarding lack of coverage of new-style classes have also been
2805 removed, since the coverage is now fairly reasonable.

2809================================
2810
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002811*Release date: 17-Jul-2008*
2812
Raymond Hettingere3ae6552008-06-20 04:18:15 +00002813Core and Builtins
2814-----------------
2815
Georg Brandl3e483f62008-07-16 22:57:41 +00002816- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2817 its methods now allow for items objects that can be converted to
2818 an integer using operator.index().
2819
Mark Dickinson64b7e502008-07-16 09:40:03 +00002820- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2821 produced a ValueError instead of giving the correct float.
2822
Eric Smitha5fa5a22008-07-16 00:11:49 +00002823- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2824 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2825
Mark Dickinson7103aa42008-07-15 19:08:33 +00002826- Issue #3008: the float type has a new instance method 'float.hex'
2827 and a new class method 'float.fromhex' to convert floating-point
2828 numbers to and from hexadecimal strings, respectively.
2829
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002830- Issue #2235: __hash__ is once again inherited by default. To allow
2831 collections.Hashable to remain meaningful in the presence of the
2832 default hash implementation (object.__hash__), it is now possible
2833 to explicit block inheritance of hash by setting __hash__=None at
2834 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2835 level.
2836
Nick Coghlanb028f502008-07-13 14:52:36 +00002837- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2838 the parent module cannot be found while performing an absolute import.
2839 This means that an incorrectly defined __package__ attribute will
2840 now only prevent relative imports in that module rather than causing
2841 all imports from that module to fail.
2842
Nick Coghlan14ff9942008-07-08 14:21:42 +00002843- Issue #2517: Allow unicode messages in Exceptions again by correctly
2844 bypassing the instance dictionary when looking up __unicode__ on
2845 new-style classes.
2846
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002847- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2848 set to a custom object whose write() method happens to install
2849 another file in sys.stdout.
2850
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002851- Issue #3088: Corrected a race condition in classes derived from
2852 threading.local: the first member set by a thread could be saved in
2853 another thread's dictionary.
2854
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002855- Issue #3004: Minor change to slice.indices(): the start and stop
2856 arguments are now treated identically, making the behaviour easier
2857 to describe and understand. For example, slice(None, -10,
2858 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2859 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2860 10, -1).
2861
Georg Brandl278fc502008-07-19 12:46:12 +00002862- Issue #3219: Calling a function with repeated keyword arguments,
2863 f(a=2, a=23), would not cause a syntax error. This was a regression
2864 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002865
Georg Brandl278fc502008-07-19 12:46:12 +00002866- Issue #2862: Make int and float freelist management consistent with
2867 other freelists. Changes their CompactFreeList apis into
2868 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00002869

2871-------
2872
Thomas Heller57adf222008-08-14 19:10:48 +00002873- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2874 api functions without holding the GIL, which could lead to a fatal
2875 error when they failed.
2876
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002877- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00002885- Issue #3125: Remove copy_reg in multiprocessing and replace it with
2886 ForkingPickler.register() to resolve conflict with ctypes.
2887
Vinay Sajip51e65192008-07-18 09:01:10 +00002888- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00002889
Thomas Heller880f5292008-07-15 19:39:38 +00002890- Issue #3313: Fixed a crash when a failed dlopen() call does not set
2891 a valid dlerror() message.
2892
Thomas Heller2bad6572008-07-15 17:19:50 +00002893- Issue #3258: Fixed a crash when a ctypes POINTER type to an
2894 incomplete structure was created.
2895
Brett Cannon3d0b9f02008-07-13 01:15:07 +00002896- Issue #3339: dummy_thread.acquire() should not return None.
2897
Raymond Hettingerb01713e2008-07-10 14:34:57 +00002898- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
2899
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002900- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00002901
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002902- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2903 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002904 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002905 content-length. The problem had been corrected in the 2.4 branch, but never
2906 merged into trunk.
2907
Georg Brandle78fbcc2008-07-05 10:13:36 +00002908- Issue #2663: add filtering capability to shutil.copytree().

2913
2914- Issue #1746: Correct handling of zipfile archive comments (previously
2915 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00002916 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00002917
Vinay Sajip51e65192008-07-18 09:01:10 +00002918- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002919 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00002920
Nick Coghlanc060b0e2008-07-02 13:09:19 +00002921- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
2922 handling is now the same as that of other special attributes like __name__).
2923
Brett Cannon8bb8fa52008-07-02 01:57:08 +00002924- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Georg Brandl5cc774e2008-06-11 20:28:06 +00003314 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003315
3316 This is controlled by the configure argument ``--with-universal-archs``:
3317
3318 - ``--with-universal-archs=all``: install 4-way universal
3319
3320 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3321
3322 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3323
3324 This option should be used in combination with ``--enable-universalsdk=``.
3325
3326 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 +00003376- Issue #1631171: Re-implement the 'warnings' module in C (the
3377 original Python code has been kept as backup). This will allow for
3378 using the 'warning's machinery in such places as the parser where
3379 use of pure Python code is not possible. Both the ``showarning()``
3380 and ``formatwarning()`` gain an optional 'line' argument which is
3381 not called by default for backwards-compatibility reasons. Setting
3382 ``warnings.showwarning()`` to an implementation that lacks support
3383 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003446- Issue #2550: The approach used by client/server code for obtaining
3447 ports to listen on in network-oriented tests has been refined in an
3448 effort to facilitate running multiple instances of the entire
3449 regression test suite in parallel without issue.
3450 test_support.bind_port() has been fixed such that it will always
3451 return a unique port -- which wasn't always the case with the
3452 previous implementation, especially if socket options had been set
3453 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3454 new implementation of bind_port() will actually raise an exception
3455 if it is passed an AF_INET/SOCK_STREAM socket with either the
3456 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3457 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3458 the socket it's been passed. This currently only applies to
3459 Windows. This option prevents any other sockets from binding to the
3460 host/port we've bound to, thus removing the possibility of the
3461 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3462 when a second SOCK_STREAM socket binds and accepts to a host/port
3463 that's already been bound by another socket. The optional preferred
3464 port parameter to bind_port() has been removed. Under no
3465 circumstances should tests be hard coding ports!
3466
3467 test_support.find_unused_port() has also been introduced, which will
3468 pass a temporary socket object to bind_port() in order to obtain an
3469 unused port. The temporary socket object is then closed and
3470 deleted, and the port is returned. This method should only be used
3471 for obtaining an unused port in order to pass to an external program
3472 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3473 a parameter to a server-oriented class that doesn't give you direct
3474 access to the underlying socket used.
3475
3476 Finally, test_support.HOST has been introduced, which should be used
3477 for the host argument of any relevant socket calls (i.e. bind and
3478 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003479
3480 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003481 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003482 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3483 test_asynchat and test_socket_ssl.
3484
Georg Brandl3ee81df2008-05-17 18:14:43 +00003485 It is now possible for multiple instances of the regression test
3486 suite to run in parallel without issue.

3752Core and builtins
3753-----------------
3754
Fred Drakea8ee94b2008-03-01 02:45:07 +00003755- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003756 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00003757
Georg Brandlad61bc82008-02-23 15:11:18 +00003758- Issue #2067: file.__exit__() now calls subclasses' close() method.
3759
3760- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003761
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003762- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003763 issue 215555 for a discussion.
3764
Eric Smitha73fbe72008-02-23 03:09:44 +00003765- Added the future_builtins module, which contains hex() and oct().
3766 These are the PEP 3127 version of these functions, designed to be
3767 compatible with the hex() and oct() builtins from Python 3.0. They
3768 differ slightly in their output formats from the existing, unchanged
3769 Python 2.6 builtins. The expected usage of the future_builtins
3770 module is:
3771 from future_builtins import hex, oct
3772
Eric Smith7ef40bf2008-02-20 23:34:22 +00003773- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3774 exponents for exponents with absolute value < 100. Follows C99
3775 standard. This is a change on Windows, which would use 3 digits.
3776 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3777 so that any alterations it does to the resulting string will be
3778 available in stringlib/formatter.h (for float.__format__).
3779
Eric Smith5a3c1352008-02-19 13:21:56 +00003780- Implemented PEP 3101, Advanced String Formatting. This adds a new
3781 builtin format(); a format() method for str and unicode; a
3782 __format__() method to object, str, unicode, int, long, float, and
3783 datetime; the class string.Formatter; and the C API
3784 PyObject_Format().
3785
Georg Brandl3ee81df2008-05-17 18:14:43 +00003786- Fixed several potential crashes, all caused by specially crafted
3787 __del__ methods exploiting objects in temporarily inconsistent
3788 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003789
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003790- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003791 prevent a possible crash: an Abstract Base Class would try to access
3792 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003793
Georg Brandl3ee81df2008-05-17 18:14:43 +00003794- Fixed repr() and str() of complex numbers with infinity or nan as
3795 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003796
Georg Brandl3ee81df2008-05-17 18:14:43 +00003797- Clear all free lists during a gc.collect() of the highest generation
3798 in order to allow pymalloc to free more arenas. Python may give back
3799 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003800
Georg Brandl3ee81df2008-05-17 18:14:43 +00003801- Issue #2045: Fix an infinite recursion triggered when printing a
3802 subclass of collections.defaultdict, if its default_factory is set
3803 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003804
Christian Heimesf75dbef2008-02-08 00:11:31 +00003805- Fixed a minor memory leak in dictobject.c. The content of the free
3806 list was not freed on interpreter shutdown.
3807
Georg Brandl21e99f42010-03-07 15:23:59 +00003808- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003809 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003810
Georg Brandl3ee81df2008-05-17 18:14:43 +00003811- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3812 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003813 to compact the internal free lists of pre-allocted ints and floats.
3814
Georg Brandl3ee81df2008-05-17 18:14:43 +00003815- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3816 calls. Python expected the return type int but the fork familie
3817 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003818
Georg Brandl3ee81df2008-05-17 18:14:43 +00003819- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3820 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003821
Georg Brandl3ee81df2008-05-17 18:14:43 +00003822- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3823 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003824
Georg Brandl3ee81df2008-05-17 18:14:43 +00003825- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3826 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003827
Georg Brandl3ee81df2008-05-17 18:14:43 +00003828- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3829 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003830
Georg Brandl3ee81df2008-05-17 18:14:43 +00003831- Patch #1473257: generator objects gain a gi_code attribute. This is
3832 the same object as the func_code attribute of the function that
3833 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003834
Georg Brandl3ee81df2008-05-17 18:14:43 +00003835- Issue #1920: "while 0" statements were completely removed by the
3836 compiler, even in the presence of an "else" clause, which is
3837 supposed to be run when the condition is false. Now the compiler
3838 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003839
Guido van Rossumeead05f2008-01-24 18:21:02 +00003840- A few crashers fixed: weakref_in_del.py (issue #1377858);
3841 loosing_dict_ref.py (issue #1303614, test67.py);
3842 borrowed_ref_[34].py (not in tracker).
3843
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003844- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003845 suppressed while an extension is loaded by calling SetErrorMode in
3846 dynload_win.c. The error is still reported properly.
3847
Georg Brandl3ee81df2008-05-17 18:14:43 +00003848- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003849 several extension methods and modules do not work without unicode
3850 support.
3851
Georg Brandl26543b12008-01-21 18:36:51 +00003852- Issue #1882: when compiling code from a string, encoding cookies in the
3853 second line of code were not always recognized correctly.
3854
Georg Brandl14404b62008-01-19 19:27:05 +00003855- Issue #1679: "0x" was taken as a valid integer literal.
3856
Georg Brandl6caad7d2008-01-26 14:19:22 +00003857- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003858 added.
3859
Christian Heimesc94e2b52008-01-14 04:13:37 +00003860- sys.float_info / PyFloat_GetInfo: The floating point information
3861 object was converted from a dict to a specialized structseq object.
3862
Georg Brandl3ee81df2008-05-17 18:14:43 +00003863- Patch #1816: Added sys.flags structseq. It exposes the status of
3864 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003865
Georg Brandl3ee81df2008-05-17 18:14:43 +00003866- Objects/structseq.c: Implemented new structseq representation. The
3867 patch makes structseqs (e.g. the return value of os.stat) more
3868 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003869
Georg Brandl3ee81df2008-05-17 18:14:43 +00003870- Patch #1700288: added a type attribute cache that caches method
3871 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003872
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003873- Bug #1776: __import__() no longer accepts filenames on any platform.
3874 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003875
Georg Brandlaed6c662008-01-07 17:25:53 +00003876- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3877
Georg Brandl3ee81df2008-05-17 18:14:43 +00003878- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3879 envvar and sys.dont_write_bytecode attribute. All these can be set
3880 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003881
Georg Brandl3ee81df2008-05-17 18:14:43 +00003882- Improve some exception messages when Windows fails to load an
3883 extension module. Now we get for example '%1 is not a valid Win32
3884 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003885
Georg Brandl3ee81df2008-05-17 18:14:43 +00003886- Bug #1481296: Fixed long(float('nan')) != 0L.
Christian Heimes8267d1d2008-01-04 00:37:34 +00003887
Georg Brandl3ee81df2008-05-17 18:14:43 +00003888- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3889 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003890
Christian Heimes0a8143f2007-12-18 23:22:54 +00003891- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003892 and INF. float("nan"), float("inf") and float("-inf") now work on
3893 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003894
Georg Brandl3ee81df2008-05-17 18:14:43 +00003895- Compiler now generates simpler and faster code for dictionary
3896 literals. The oparg for BUILD_MAP now indicates an estimated
3897 dictionary size. There is a new opcode, STORE_MAP, for adding
3898 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00003899
Georg Brandl3ee81df2008-05-17 18:14:43 +00003900- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003905- Issue #1538: Avoid copying string in split/rsplit if the split char
3906 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00003907
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00003908- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00003909 SystemError.
3910
Nick Coghlanef01d822007-12-03 12:55:17 +00003911- PEP 366: Allow explicit relative imports when executing modules
3912 inside packages with the -m switch via a new module level
3913 __package__ attribute.
3914
Georg Brandl3ee81df2008-05-17 18:14:43 +00003915- Issue #1402: Fix a crash on exit, when another thread is still
3916 running, and if the deallocation of its frames somehow calls the
3917 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00003918

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00003922 attribute of an empty cell object.
3923
Georg Brandl3ee81df2008-05-17 18:14:43 +00003924- Issue #1460: The utf-7 incremental decoder did not accept truncated
3925 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00003926
Georg Brandl3ee81df2008-05-17 18:14:43 +00003927- Patch #1739468: Directories and zipfiles containing a __main__.py
3928 file can now be directly executed by passing their name to the
3929 interpreter. The directory/zipfile is automatically inserted as the
3930 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003931
Georg Brandl3ee81df2008-05-17 18:14:43 +00003932- Issue #1265: Fix a problem with sys.settrace, if the tracing
3933 function uses a generator expression when at the same time the
3934 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003935
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003936- sets and frozensets now have an isdisjoint() method.
3937
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003938- optimize the performance of builtin.sum().
3939
Neal Norwitz44f326e2007-10-05 05:29:17 +00003940- Fix warnings found by the new version of the Coverity checker.
3941
Georg Brandl21e99f42010-03-07 15:23:59 +00003942- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003943 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3944 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003945
Georg Brandl3ee81df2008-05-17 18:14:43 +00003946- Issue #1686386: Tuple's tp_repr did not take into account the
3947 possibility of having a self-referential tuple, which is possible
3948 from C code. Nor did object's tp_str consider that a type's tp_str
3949 could do something that could lead to an inifinite recursion.
3950 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3951 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003952
Georg Brandl3ee81df2008-05-17 18:14:43 +00003953- Issue #1164: It was possible to trigger deadlock when using the
3954 'print' statement to write to a file since the GIL was not released
3955 as needed. Now PyObject_Print() does the right thing along with
3956 various tp_print implementations of the built-in types and those in
3957 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003958
Georg Brandl3ee81df2008-05-17 18:14:43 +00003959- Issue #1147: Exceptions were directly allowing string exceptions in
3960 their throw() method even though string exceptions no longer
3961 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003962

Brett Cannon1e534b52007-09-07 04:18:30 +00003966- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003967 PyObject_Call() never calling back out to Python code to trigger
3968 recursion depth updates/checks. Required the creation of a static
3969 RuntimeError instance in case normalizing an exception put the
3970 recursion check value past its limit. Fixes crashers
3971 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003972
Georg Brandl3ee81df2008-05-17 18:14:43 +00003973- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00003986- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003987 __*__ attributes. (Some already existed, e.g., __doc__ and
3988 __name__.)

Georg Brandl3ee81df2008-05-17 18:14:43 +00003997 "except E as target:". This is to provide forwards compatibility
3998 with Python 3.0.

4018
Guido van Rossum143b5642007-03-23 04:58:42 +00004019- Bug #1683368: The object.__init__() and object.__new__() methods are
4020 now stricter in rejecting excess arguments. The only time when
4021 either allows excess arguments is when it is not overridden and the
4022 other one is. For backwards compatibility, when both are
4023 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004024 warning later). Also, type.__init__() insists on the same signature
4025 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004026
Georg Brandl3ee81df2008-05-17 18:14:43 +00004027- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4028 object to complex using its __complex__() method before falling back
4029 to the __float__() method. Therefore, the functions in the cmath
4030 module now can operate on objects that define a __complex__()
4031 method.

4048
Georg Brandl7b9c5552007-03-12 14:30:05 +00004049- Bug #1678647: write a newline after printing an exception in any
4050 case, even when converting the value to a string failed.
4051
Georg Brandl871f1bc2007-03-12 13:17:36 +00004052- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004053 its argument, if it exists. If not, it will work like before. This
4054 allows customizing the output of dir() in the presence of a
4055 __getattr__().

4064 parthensized forms. This means complex(repr(x)) now works instead of
4065 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004066
Georg Brandlaa2321b2007-03-07 00:40:28 +00004067- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004068 makes the filenames the warning module prints much more sensible
4069 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004070

Georg Brandl0fca97a2007-03-05 22:28:08 +00004082- Patch #1674228: when assigning a slice (old-style), check for the
4083 sq_ass_slice instead of the sq_slice slot.
4084
Georg Brandl3ee81df2008-05-17 18:14:43 +00004085- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00004711- unittest now verifies more of its assumptions. In particular,
4712 TestCase and TestSuite subclasses (not instances) are no longer
4713 accepted in TestSuite.addTest(). This should cause no
4714 incompatibility since it never made sense with ordinary subclasses
4715 -- the failure just occurred later, with a more cumbersome
4716 exception.

4999 obtained from the TLS negotiation itself. Patch contributed by Bill
5000 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00005001
Georg Brandl3ee81df2008-05-17 18:14:43 +00005002- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005003 that the SMTP.starttls() caller no longer needs to call ehlo()
5004 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00005005 does not claim to support starttls. Adds the
5006 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

5087 complex, tuple, list, dict, set, and frozenset. Formerly, it would
5088 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00005105 time so that opening a database previously created with the DB_DUP
5106 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5107 opens. Specifically: dictionary assignment to a DB object will
5108 replace all values for a given key when the database allows
5109 duplicate values. DB users should use DB.put(k, v) when they want
5110 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005111

5117 characters with ASCII value less than 32. Also, it correctly quotes
5118 dots only if they occur on a single line, as opposed to the previous
5119 behavior of quoting dots if they are the second character of any
5120 line.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005445- Unified naming convention for free lists and their limits. All free
5446 lists in Object/ are named ``free_list``, the counter ``numfree``
5447 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
5448 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00005449
Georg Brandl3ee81df2008-05-17 18:14:43 +00005450- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5451 to ``PyTuple_SetItem``, it can be used to populate a brand new
5452 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00005453
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005454- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00005455
Georg Brandl3ee81df2008-05-17 18:14:43 +00005456- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
5457 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
5458 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005459
5460- Patch #1720595: add T_BOOL to the range of structmember types.
5461
5462- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
5463 ``PyFloat_GetInfo()`` to the float API.
5464
Georg Brandl3ee81df2008-05-17 18:14:43 +00005465- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5466 of w# format code incorrectly truncated the length to an int, even
5467 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5468 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005469
Georg Brandl3ee81df2008-05-17 18:14:43 +00005470- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
5471 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005472
Georg Brandl3ee81df2008-05-17 18:14:43 +00005473- PEP 3123: Provide forward compatibility with Python 3.0, while
5474 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
5475 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005476
Georg Brandl3ee81df2008-05-17 18:14:43 +00005477- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
5478 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005479
5480- Patch #1733960: Allow T_LONGLONG to accept ints.
5481
5482- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
5483
Christian Heimes000a0742008-01-03 22:16:32 +00005484- Added a new API function ``PyImport_ImportModuleNoBlock``.
5485
Georg Brandl6caad7d2008-01-26 14:19:22 +00005486- Bug #1637022: Prefix AST symbols with _Py_.
5487
5488- Fix some leftovers from the conversion from int to Py_ssize_t
5489 (relevant to strings and sequences of more than 2**31 items).
5490
5491- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5492 outside of pystate.c and should not be necessary.
5493
Georg Brandl3ee81df2008-05-17 18:14:43 +00005494- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5495 absolute imports. In earlier versions they might have used relative
5496 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005497
Georg Brandl3ee81df2008-05-17 18:14:43 +00005498- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5499 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005500
Georg Brandl3ee81df2008-05-17 18:14:43 +00005501- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
5502 macro so it can be used as an expression.

5507
Georg Brandl3ee81df2008-05-17 18:14:43 +00005508- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
5509 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
5510 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
5511 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00005512
Georg Brandl3ee81df2008-05-17 18:14:43 +00005513- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
5514 _CRT_NONSTDC_NO_DEPRECATE.

Brett Cannon791d56f2007-05-31 19:40:42 +00005524- buildtools now raises a DeprecationWarning.
5525
Georg Brandl3ee81df2008-05-17 18:14:43 +00005526- Removed the macfs module. It had been deprecated since Python 2.5.
5527 This lead to the deprecation of macostools.touched() as it relied
5528 solely on macfs and was a no-op under OS X.
