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

257 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +0000258 library would return a bogus result; on Solaris, it was possible to crash the
259 interpreter. Patch by Stefan Krah.

Mark Dickinson36ecd672010-01-29 17:11:39 +0000271
Georg Brandlba83f822010-03-14 09:50:54 +0000272- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
273 and add the additional members returned in an OSVERSIONINFOEX structure. The
274 new members are service_pack_major, service_pack_minor, suite_mask, and
275 product_type.

Georg Brandlba83f822010-03-14 09:50:54 +0000277- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
278 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
279 returning NULL. The macro now returns a statically allocated empty string
280 instead.

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

309 interpreter shutdown.
310
Georg Brandlba83f822010-03-14 09:50:54 +0000311- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">") in
312 XML processing instructions and comments. These raw characters are allowed
313 by the XML specification, and are necessary when outputting e.g. PHP code in
314 a processing instruction. Patch by Neil Muller.

Vinay Sajip0e6e97d2010-02-04 20:23:45 +0000321
Antoine Pitroud840e512010-02-04 20:20:18 +0000322- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +0000323 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +0000324 Also, raise ValueError rather than TypeError when an unknown TIPC address
325 type is specified. Patch by Brian Curtin.
326
Vinay Sajip28c382f2010-02-04 18:48:53 +0000327- logging: Implemented PEP 391.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000329- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +0000330 file position when calling `truncate()`. It would previously change the file
331 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000332 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
333
Benjamin Petersone06f7112010-01-28 02:15:02 +0000334- UserDict is now a new-style class.
335
Georg Brandlba83f822010-03-14 09:50:54 +0000336- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
337 class used to represent files stored inside an archive. The new
338 implementation is significantly faster and can be wrapped in a
339 ``io.BufferedReader`` object for more speedups. It also solves an issue
340 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
341 Patch by Nir Aides.
Antoine Pitrou94c33eb2010-01-27 20:59:50 +0000342
Benjamin Peterson2deb5c72010-01-27 02:16:42 +0000343- Issue #7792: Registering non-classes to ABCs raised an obscure error.
344

Georg Brandlba83f822010-03-14 09:50:54 +0000348- Issue #7773: Fix an UnboundLocalError in ``platform.linux_distribution()``
349 when the release file is empty.
Benjamin Petersona43f34c2010-01-25 03:31:13 +0000350
Georg Brandlba83f822010-03-14 09:50:54 +0000351- Issue #7748: Since unicode values are supported for some metadata options in
352 Distutils, the DistributionMetadata get_* methods will now return an utf-8
353 encoded string for them. This ensures that the upload and register commands
354 send the correct values to PyPI without any error.
Tarek Ziadéf14c7fc2010-01-24 00:33:32 +0000355
Georg Brandlba83f822010-03-14 09:50:54 +0000356- Issue #1670765: Prevent ``email.generator.Generator`` from re-wrapping
R. David Murrayed44dfa2010-01-16 05:15:17 +0000357 headers in multipart/signed MIME parts, which fixes one of the sources of
358 invalid modifications to such parts by Generator.

428Core and Builtins
429-----------------
430
Georg Brandlba83f822010-03-14 09:50:54 +0000431- The ``__complex__()`` method is now looked up on the class of instances to
432 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000434- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
435 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
436
Mark Dickinson1b34d252010-01-01 17:27:30 +0000437- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000438 DeprecationWarning when passed a float argument where an integer was expected.
439 These functions and methods now raise TypeError instead. The majority of the
440 effects of this change are in the extension modules, but some core functions
441 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
442 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +0000455- Issue #1811: Improve accuracy and cross-platform consistency for true division
456 of integers: the result of a/b is now correctly rounded for ints a and b (at
457 least on IEEE 754 platforms), and in particular does not depend on the
458 internal representation of a long.

466
Georg Brandlba83f822010-03-14 09:50:54 +0000467 These executables now work properly with the arch(1) command: ``arch -ppc
468 python`` will start a universal binary version of python in PPC mode (unlike
469 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +0000607- Issue #3382: 'F' formatting for float and complex now convert the result to
608 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
609 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000610
Georg Brandlba83f822010-03-14 09:50:54 +0000611- Remove switch from "%f" formatting to "%g" formatting for floats larger than
612 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000613
Georg Brandlba83f822010-03-14 09:50:54 +0000614- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
615 1e-100 used to raise OverflowError, but now gives the requested 120
616 significant digits instead.

623 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000624
Georg Brandlba83f822010-03-14 09:50:54 +0000625- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
626 decimal string that's guaranteed to round back to x under correct rounding
627 (with round-half-to-even rounding mode). Previously it gave a string based on
628 rounding x to 17 decimal digits. repr(x) for a complex number behaves
629 similarly. On platforms where the correctly-rounded strtod and dtoa code is
630 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000631
Georg Brandlba83f822010-03-14 09:50:54 +0000632- Issue #7117: On almost all platforms: float-to-string and string-to-float
633 conversions within Python are now correctly rounded. Places these conversions
634 occur include: str for floats and complex numbers; the float and complex
635 constructors; old-style and new-style numeric formatting; serialization and
636 deserialization of floats and complex numbers using marshal, pickle and json;
637 parsing of float and imaginary literals in Python code; Decimal-to-float
638 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000639
Georg Brandlba83f822010-03-14 09:50:54 +0000640 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
641 providing correctly-rounded strtod and dtoa C functions. This code is
642 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
643 the C compiler. There may be a small number of platforms on which correct
644 operation of this code cannot be guaranteed, so the code is not used: notably,
645 this applies to platforms where the C double format is not IEEE 754 binary64,
646 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
647 and Python's configure script is unable to determine how to change the FPU
648 precision. On these platforms conversions use the platform strtod and dtoa,
649 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000650
Georg Brandlba83f822010-03-14 09:50:54 +0000651- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
652 uses the correctly-rounded string <-> float conversions described above (when
653 available), and so produces correctly rounded results that will display nicely
654 under the float repr. There are two related small changes: (1) round now
655 accepts any class with an ``__index__()`` method for its second argument (but
656 no longer accepts floats for the second argument), and (2) an excessively
657 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
658 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +0000662- Fix several issues with ``compile()``. The input can now contain Windows and

Mark Dickinsonb1d45852009-05-11 15:33:08 +0000800
Georg Brandlba83f822010-03-14 09:50:54 +0000801 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
802 (2) parsing of strings representing infinities and nans was locale aware; and
803 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +0000805- Issue #5920: For ``float.__format__()``, change the behavior with the empty
806 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
807 but with at least one decimal point and with a default precision
808 of 12. Previously, the behavior the same but with a default precision of 6.
809 This more closely matches ``str()``, and reduces surprises when adding
810 alignment flags to the empty presentation type. This also affects the new
811 complex.__format__ in the same way.
812
813- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

Georg Brandl6425a2f2008-12-28 11:54:53 +0000974- Issue #4759: None is now allowed as the first argument of
Georg Brandlba83f822010-03-14 09:50:54 +0000975 ``bytearray.translate()``. It was always allowed for ``bytes.translate()``.

Skip Montanarof205c132008-12-23 03:30:15 +0000977- Added test case to ensure attempts to read from a file opened for writing

Georg Brandlba83f822010-03-14 09:50:54 +0000994- Issue #4445: Replace ``sizeof(PyStringObject)`` with
995 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
996 instances. On a typical machine this saves 3 bytes of memory (on average) per
997 string allocation.

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000999- Issue #3996: On Windows, the PyOS_CheckStack function would cause the

1001 instead of throwing a MemoryError.
1002
Georg Brandlba83f822010-03-14 09:50:54 +00001003- Issue #3689: The list reversed iterator now supports __length_hint__ instead

1008
Georg Brandlba83f822010-03-14 09:50:54 +00001009- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
1010 file objects with closefd=False. The file descriptor is still kept open but
1011 the file object behaves like a closed file. The ``FileIO`` object also got a
1012 new readonly attribute ``closefd``.

1030 __future__ import didn't work.
1031
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00001032- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00001033 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00001034
Georg Brandlba83f822010-03-14 09:50:54 +00001035- On windows, ``os.chdir()`` given unicode was not working if
1036 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
1037 this code path is really executed because I cannot move to such directory on
1038 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00001040- Issue #4069: When ``set.remove(element)`` is used with a set element, the
1041 element is temporarily replaced with an equivalent frozenset. But the
1042 eventual KeyError would always report the empty ``frozenset()`` as the missing
1043 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00001063- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
1064 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1065 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1066 of using the replace error handler in PyUnicode_DecodeUTF8().
1067
Walter Dörwald726ba8e2009-05-06 14:32:35 +00001068- Issue #3739: The unicode-internal encoder now reports the number of characters

1070
Georg Brandlba83f822010-03-14 09:50:54 +00001071- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
1072 allocator will be automatically disabled when running under Valgrind. This
1073 gives improved memory leak detection when running under Valgrind, while taking
1074 advantage of pymalloc at other times.

2241 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
2242 neither __int__ nor __long__, TypeError used to be raised (with a
2243 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and

Georg Brandlba83f822010-03-14 09:50:54 +00002297 leak-chasing test runs give sensible results. The previous method of reaping

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002439- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2440
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002441- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2442 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2443 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2444 ``printf`` function, whereas PyString_FromFormat has an independent
2445 implementation and uses "%zd" on all platforms for size_t values.
2446 This makes a difference on win64, where ``printf`` needs "%Id" to display
2447 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00002449- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

2453 object; previously an int would be returned for small values. the __long__
2454 method is allowed to return either an int or a long, but the behaviour of
2455 float objects should not change to respect backward compatibility.
2456
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002457- Issue #3751: str.rpartition would perform a left-partition when called with
2458 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +00002463 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002464 was correctly parsed but parsing of subsequent arguments failed.
2465
Vinay Sajip35e3b032008-09-01 14:33:59 +00002466- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002467 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2468 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2469 when given a tuple of classes as second argument, were looking up
2470 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2471 type object.
2472
Neal Norwitz18aa3882008-08-24 05:04:52 +00002473- Fix crashes on memory allocation failure found with failmalloc.

2616-----------------
2617
Guido van Rossumf8402962008-08-20 15:01:50 +00002618- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2619 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2620 extensions do not automatically benefit from the class attribute
2621 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2622 to their tp_flags field if they care. This is a backwards
2623 compatibility feature; in 3.0, all types will use the cache by
2624 default.
2625
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002626- Keyword arguments can now follow starred arguments. (``f(a, *args,

2630 value again.

Mark Dickinsonb6467572008-08-04 21:30:09 +00002639- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2640 ValueError consistently across platforms.
2641
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002642- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2643 (64bit Unix, for example), unichr() would truncate its argument and return
2644 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2645
Neal Norwitze7d8be82008-07-31 17:17:14 +00002646- Apply security patches from Apple.
2647
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002648- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2649 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2650
Antoine Pitrou92f82162008-07-25 22:22:08 +00002651- Issue #1819: function calls with several named parameters are now on
2652 average 35% faster (as measured by pybench).
2653
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002654- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2655 the python debugger steps into a class statement: the free variables (local
2656 variables defined in an outer scope) would be deleted from the outer scope.
2657
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002658- Issue #2620: Overflow checking when allocating or reallocating memory
2659 was not always being done properly in some python types and extension
2660 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2661 all been updated to perform better checks and places in the code that
2662 would previously leak memory on the error path when such an allocation
2663 failed have been fixed.

2669
Benjamin Petersone977ad42008-08-20 01:42:01 +00002670- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2671 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2672
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002673- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2674 version reported by these tools does not necessarily follow the python
2675 version numbering scheme, so the module is less strict when parsing it.
2676
Nick Coghlanf70385a2008-08-18 12:42:46 +00002677- Issue #2235: Added Py3k warnings for types which will become unhashable
2678 under the stricter __hash__ inheritance rules in 3.0. Several types
2679 which did not meet the rules for hash invariants and were already
2680 unhashable in 3.0 have now been explicitly flagged as unhashable in
2681 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2682 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2683
Brett Cannon88f801d2008-08-18 00:46:22 +00002684- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2685 imported into the module but exposed as part of the module's API.
2686

2692
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002693- Issue #3575: Incremental decoder's decode function now takes bytearray
2694 by using 's*' instead of 't#'.
2695
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002696- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002697 fails unicode conversion on 2nd parameter. (windows only)

Facundo Batistaeb90b782008-08-16 14:44:07 +00002705- Issue #2776: fixed small issue when handling an URL with double slash
2706 after a 302 response in the case of not going through a proxy.
2707
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002708- Issue #2676: in the email package, content-type parsing was hanging on
2709 pathological input because of quadratic or exponential behaviour of a
2710 regular expression.
2711
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002712- Issue #3476: binary buffered reading through the new "io" library is now
2713 thread-safe.
2714
Brett Cannonbf3157b2008-08-14 05:00:03 +00002715- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2716 since mimetools itself is deprecated. Because modules are cached, all
2717 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2718
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002719- Issue #3134: shutil referenced undefined WindowsError symbol.

Robert Schuppenies14646332008-08-10 11:01:53 +00002721- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2722 menu entries were not deleted.
2723
Brett Cannon83e81842008-08-09 23:30:55 +00002724- Copied the implementation of reduce() to _functools.reduce() to have a
2725 version that did not raise a DeprecationWarning under -3.
2726
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002727- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2728 a MemoryError rather than silently stop the iteration.
2729
Guido van Rossum59ce9012008-08-09 14:55:34 +00002730- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2731 to _sre.compile() will now be rejected. This should not affect anybody
2732 since the re.compile() function never generates invalid re-bytecode.
2733
Skip Montanaroa032bf42008-08-08 22:52:51 +00002734- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2735 upon first access it can be automatically initialized from the csv file if
2736 it wasn't initialized during instantiation.
2737
Brett Cannon3aa2a492008-08-06 22:28:09 +00002738- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2739 the reload() built-in has been removed.
2740
Brett Cannon7e30b672008-08-04 21:52:25 +00002741- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002742 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

2750 raised an AttributeError.
2751
Benjamin Peterson01a24322008-07-28 23:35:27 +00002752- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002753 asking for a specific length. This problem only affected files opened
2754 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002755

2778
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002779- Issue #3394: zipfile.writestr sets external attributes when passed a
2780 file name rather than a ZipInfo instance, so files are extracted with
2781 mode 0600 rather than 000 under Unix.
2782
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002783- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2784 argument in python 2.5, this broke code that subclassed Popen to include its
2785 own poll method. Fixed my moving _deadstate to an _internal_poll method.

2794
Nick Coghlan6e8fef02008-08-18 13:14:22 +00002795- Issue #2235: the C API function PyObject_HashNotImplemented and its
2796 interaction with the tp_hash slot (added in 2.6b2) are now documented
2797
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002798- Issue #643841: The language reference now provides more detailed
2799 coverage of the lookup process for special methods. The disclaimers
2800 regarding lack of coverage of new-style classes have also been
2801 removed, since the coverage is now fairly reasonable.

2805================================
2806
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002807*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00002809Core and Builtins
2810-----------------
2811
Georg Brandl3e483f62008-07-16 22:57:41 +00002812- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2813 its methods now allow for items objects that can be converted to
2814 an integer using operator.index().
2815
Mark Dickinson64b7e502008-07-16 09:40:03 +00002816- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2817 produced a ValueError instead of giving the correct float.
2818
Eric Smitha5fa5a22008-07-16 00:11:49 +00002819- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2820 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2821
Mark Dickinson7103aa42008-07-15 19:08:33 +00002822- Issue #3008: the float type has a new instance method 'float.hex'
2823 and a new class method 'float.fromhex' to convert floating-point
2824 numbers to and from hexadecimal strings, respectively.
2825
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002826- Issue #2235: __hash__ is once again inherited by default. To allow
2827 collections.Hashable to remain meaningful in the presence of the
2828 default hash implementation (object.__hash__), it is now possible
2829 to explicit block inheritance of hash by setting __hash__=None at
2830 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2831 level.
2832
Nick Coghlanb028f502008-07-13 14:52:36 +00002833- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2834 the parent module cannot be found while performing an absolute import.
2835 This means that an incorrectly defined __package__ attribute will
2836 now only prevent relative imports in that module rather than causing
2837 all imports from that module to fail.
2838
Nick Coghlan14ff9942008-07-08 14:21:42 +00002839- Issue #2517: Allow unicode messages in Exceptions again by correctly
2840 bypassing the instance dictionary when looking up __unicode__ on
2841 new-style classes.
2842
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002843- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2844 set to a custom object whose write() method happens to install
2845 another file in sys.stdout.
2846
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002847- Issue #3088: Corrected a race condition in classes derived from
2848 threading.local: the first member set by a thread could be saved in
2849 another thread's dictionary.
2850
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002851- Issue #3004: Minor change to slice.indices(): the start and stop
2852 arguments are now treated identically, making the behaviour easier
2853 to describe and understand. For example, slice(None, -10,
2854 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2855 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2856 10, -1).
2857
Georg Brandl278fc502008-07-19 12:46:12 +00002858- Issue #3219: Calling a function with repeated keyword arguments,
2859 f(a=2, a=23), would not cause a syntax error. This was a regression
2860 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002861
Georg Brandl278fc502008-07-19 12:46:12 +00002862- Issue #2862: Make int and float freelist management consistent with
2863 other freelists. Changes their CompactFreeList apis into
2864 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00002865

2867-------
2868
Thomas Heller57adf222008-08-14 19:10:48 +00002869- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2870 api functions without holding the GIL, which could lead to a fatal
2871 error when they failed.
2872
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002873- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

2882 ForkingPickler.register() to resolve conflict with ctypes.
2883
Vinay Sajip51e65192008-07-18 09:01:10 +00002884- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00002885
Thomas Heller880f5292008-07-15 19:39:38 +00002886- Issue #3313: Fixed a crash when a failed dlopen() call does not set
2887 a valid dlerror() message.
2888
Thomas Heller2bad6572008-07-15 17:19:50 +00002889- Issue #3258: Fixed a crash when a ctypes POINTER type to an
2890 incomplete structure was created.
2891
Brett Cannon3d0b9f02008-07-13 01:15:07 +00002892- Issue #3339: dummy_thread.acquire() should not return None.
2893
Raymond Hettingerb01713e2008-07-10 14:34:57 +00002894- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
2895
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002896- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00002897
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002898- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2899 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002900 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002901 content-length. The problem had been corrected in the 2.4 branch, but never
2902 merged into trunk.
2903
Georg Brandle78fbcc2008-07-05 10:13:36 +00002904- Issue #2663: add filtering capability to shutil.copytree().

2909
2910- Issue #1746: Correct handling of zipfile archive comments (previously
2911 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00002912 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00002913
Vinay Sajip51e65192008-07-18 09:01:10 +00002914- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002915 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00002916
Nick Coghlanc060b0e2008-07-02 13:09:19 +00002917- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
2918 handling is now the same as that of other special attributes like __name__).
2919
Brett Cannon8bb8fa52008-07-02 01:57:08 +00002920- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Georg Brandl5cc774e2008-06-11 20:28:06 +00003310 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003311
3312 This is controlled by the configure argument ``--with-universal-archs``:
3313
3314 - ``--with-universal-archs=all``: install 4-way universal
3315
3316 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3317
3318 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3319
3320 This option should be used in combination with ``--enable-universalsdk=``.
3321
3322 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 +00003372- Issue #1631171: Re-implement the 'warnings' module in C (the
3373 original Python code has been kept as backup). This will allow for
3374 using the 'warning's machinery in such places as the parser where
3375 use of pure Python code is not possible. Both the ``showarning()``
3376 and ``formatwarning()`` gain an optional 'line' argument which is
3377 not called by default for backwards-compatibility reasons. Setting
3378 ``warnings.showwarning()`` to an implementation that lacks support
3379 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003442- Issue #2550: The approach used by client/server code for obtaining
3443 ports to listen on in network-oriented tests has been refined in an
3444 effort to facilitate running multiple instances of the entire
3445 regression test suite in parallel without issue.
3446 test_support.bind_port() has been fixed such that it will always
3447 return a unique port -- which wasn't always the case with the
3448 previous implementation, especially if socket options had been set
3449 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3450 new implementation of bind_port() will actually raise an exception
3451 if it is passed an AF_INET/SOCK_STREAM socket with either the
3452 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3453 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3454 the socket it's been passed. This currently only applies to
3455 Windows. This option prevents any other sockets from binding to the
3456 host/port we've bound to, thus removing the possibility of the
3457 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3458 when a second SOCK_STREAM socket binds and accepts to a host/port
3459 that's already been bound by another socket. The optional preferred
3460 port parameter to bind_port() has been removed. Under no
3461 circumstances should tests be hard coding ports!
3462
3463 test_support.find_unused_port() has also been introduced, which will
3464 pass a temporary socket object to bind_port() in order to obtain an
3465 unused port. The temporary socket object is then closed and
3466 deleted, and the port is returned. This method should only be used
3467 for obtaining an unused port in order to pass to an external program
3468 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3469 a parameter to a server-oriented class that doesn't give you direct
3470 access to the underlying socket used.
3471
3472 Finally, test_support.HOST has been introduced, which should be used
3473 for the host argument of any relevant socket calls (i.e. bind and
3474 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003475
3476 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003477 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003478 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3479 test_asynchat and test_socket_ssl.
3480
Georg Brandl3ee81df2008-05-17 18:14:43 +00003481 It is now possible for multiple instances of the regression test
3482 suite to run in parallel without issue.

3748Core and builtins
3749-----------------
3750
Fred Drakea8ee94b2008-03-01 02:45:07 +00003751- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003752 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00003753
Georg Brandlad61bc82008-02-23 15:11:18 +00003754- Issue #2067: file.__exit__() now calls subclasses' close() method.
3755
3756- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003757
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003758- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003759 issue 215555 for a discussion.
3760
Eric Smitha73fbe72008-02-23 03:09:44 +00003761- Added the future_builtins module, which contains hex() and oct().
3762 These are the PEP 3127 version of these functions, designed to be
3763 compatible with the hex() and oct() builtins from Python 3.0. They
3764 differ slightly in their output formats from the existing, unchanged
3765 Python 2.6 builtins. The expected usage of the future_builtins
3766 module is:
3767 from future_builtins import hex, oct
3768
Eric Smith7ef40bf2008-02-20 23:34:22 +00003769- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3770 exponents for exponents with absolute value < 100. Follows C99
3771 standard. This is a change on Windows, which would use 3 digits.
3772 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3773 so that any alterations it does to the resulting string will be
3774 available in stringlib/formatter.h (for float.__format__).
3775
Eric Smith5a3c1352008-02-19 13:21:56 +00003776- Implemented PEP 3101, Advanced String Formatting. This adds a new
3777 builtin format(); a format() method for str and unicode; a
3778 __format__() method to object, str, unicode, int, long, float, and
3779 datetime; the class string.Formatter; and the C API
3780 PyObject_Format().
3781
Georg Brandl3ee81df2008-05-17 18:14:43 +00003782- Fixed several potential crashes, all caused by specially crafted
3783 __del__ methods exploiting objects in temporarily inconsistent
3784 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003785
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003786- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003787 prevent a possible crash: an Abstract Base Class would try to access
3788 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003789
Georg Brandl3ee81df2008-05-17 18:14:43 +00003790- Fixed repr() and str() of complex numbers with infinity or nan as
3791 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003792
Georg Brandl3ee81df2008-05-17 18:14:43 +00003793- Clear all free lists during a gc.collect() of the highest generation
3794 in order to allow pymalloc to free more arenas. Python may give back
3795 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003796
Georg Brandl3ee81df2008-05-17 18:14:43 +00003797- Issue #2045: Fix an infinite recursion triggered when printing a
3798 subclass of collections.defaultdict, if its default_factory is set
3799 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003800
Christian Heimesf75dbef2008-02-08 00:11:31 +00003801- Fixed a minor memory leak in dictobject.c. The content of the free
3802 list was not freed on interpreter shutdown.
3803
Georg Brandl21e99f42010-03-07 15:23:59 +00003804- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003805 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003806
Georg Brandl3ee81df2008-05-17 18:14:43 +00003807- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3808 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003809 to compact the internal free lists of pre-allocted ints and floats.
3810
Georg Brandl3ee81df2008-05-17 18:14:43 +00003811- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3812 calls. Python expected the return type int but the fork familie
3813 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003814
Georg Brandl3ee81df2008-05-17 18:14:43 +00003815- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3816 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003817
Georg Brandl3ee81df2008-05-17 18:14:43 +00003818- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3819 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003820
Georg Brandl3ee81df2008-05-17 18:14:43 +00003821- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3822 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003823
Georg Brandl3ee81df2008-05-17 18:14:43 +00003824- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3825 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003826
Georg Brandl3ee81df2008-05-17 18:14:43 +00003827- Patch #1473257: generator objects gain a gi_code attribute. This is
3828 the same object as the func_code attribute of the function that
3829 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003830
Georg Brandl3ee81df2008-05-17 18:14:43 +00003831- Issue #1920: "while 0" statements were completely removed by the
3832 compiler, even in the presence of an "else" clause, which is
3833 supposed to be run when the condition is false. Now the compiler
3834 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003835
Guido van Rossumeead05f2008-01-24 18:21:02 +00003836- A few crashers fixed: weakref_in_del.py (issue #1377858);
3837 loosing_dict_ref.py (issue #1303614, test67.py);
3838 borrowed_ref_[34].py (not in tracker).
3839
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003840- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003841 suppressed while an extension is loaded by calling SetErrorMode in
3842 dynload_win.c. The error is still reported properly.
3843
Georg Brandl3ee81df2008-05-17 18:14:43 +00003844- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003845 several extension methods and modules do not work without unicode
3846 support.
3847
Georg Brandl26543b12008-01-21 18:36:51 +00003848- Issue #1882: when compiling code from a string, encoding cookies in the
3849 second line of code were not always recognized correctly.
3850
Georg Brandl14404b62008-01-19 19:27:05 +00003851- Issue #1679: "0x" was taken as a valid integer literal.
3852
Georg Brandl6caad7d2008-01-26 14:19:22 +00003853- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003854 added.
3855
Christian Heimesc94e2b52008-01-14 04:13:37 +00003856- sys.float_info / PyFloat_GetInfo: The floating point information
3857 object was converted from a dict to a specialized structseq object.
3858
Georg Brandl3ee81df2008-05-17 18:14:43 +00003859- Patch #1816: Added sys.flags structseq. It exposes the status of
3860 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003861
Georg Brandl3ee81df2008-05-17 18:14:43 +00003862- Objects/structseq.c: Implemented new structseq representation. The
3863 patch makes structseqs (e.g. the return value of os.stat) more
3864 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003865
Georg Brandl3ee81df2008-05-17 18:14:43 +00003866- Patch #1700288: added a type attribute cache that caches method
3867 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003868
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003869- Bug #1776: __import__() no longer accepts filenames on any platform.
3870 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003871
Georg Brandlaed6c662008-01-07 17:25:53 +00003872- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3873
Georg Brandl3ee81df2008-05-17 18:14:43 +00003874- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3875 envvar and sys.dont_write_bytecode attribute. All these can be set
3876 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003877
Georg Brandl3ee81df2008-05-17 18:14:43 +00003878- Improve some exception messages when Windows fails to load an
3879 extension module. Now we get for example '%1 is not a valid Win32
3880 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003881
Georg Brandl3ee81df2008-05-17 18:14:43 +00003882- Bug #1481296: Fixed long(float('nan')) != 0L.
Christian Heimes8267d1d2008-01-04 00:37:34 +00003883
Georg Brandl3ee81df2008-05-17 18:14:43 +00003884- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3885 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003886
Christian Heimes0a8143f2007-12-18 23:22:54 +00003887- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003888 and INF. float("nan"), float("inf") and float("-inf") now work on
3889 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003890
Georg Brandl3ee81df2008-05-17 18:14:43 +00003891- Compiler now generates simpler and faster code for dictionary
3892 literals. The oparg for BUILD_MAP now indicates an estimated
3893 dictionary size. There is a new opcode, STORE_MAP, for adding
3894 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00003895
Georg Brandl3ee81df2008-05-17 18:14:43 +00003896- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003901- Issue #1538: Avoid copying string in split/rsplit if the split char
3902 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00003903
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00003904- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00003905 SystemError.
3906
Nick Coghlanef01d822007-12-03 12:55:17 +00003907- PEP 366: Allow explicit relative imports when executing modules
3908 inside packages with the -m switch via a new module level
3909 __package__ attribute.
3910
Georg Brandl3ee81df2008-05-17 18:14:43 +00003911- Issue #1402: Fix a crash on exit, when another thread is still
3912 running, and if the deallocation of its frames somehow calls the
3913 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00003914

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00003918 attribute of an empty cell object.
3919
Georg Brandl3ee81df2008-05-17 18:14:43 +00003920- Issue #1460: The utf-7 incremental decoder did not accept truncated
3921 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00003922
Georg Brandl3ee81df2008-05-17 18:14:43 +00003923- Patch #1739468: Directories and zipfiles containing a __main__.py
3924 file can now be directly executed by passing their name to the
3925 interpreter. The directory/zipfile is automatically inserted as the
3926 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003927
Georg Brandl3ee81df2008-05-17 18:14:43 +00003928- Issue #1265: Fix a problem with sys.settrace, if the tracing
3929 function uses a generator expression when at the same time the
3930 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003931
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003932- sets and frozensets now have an isdisjoint() method.
3933
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003934- optimize the performance of builtin.sum().
3935
Neal Norwitz44f326e2007-10-05 05:29:17 +00003936- Fix warnings found by the new version of the Coverity checker.
3937
Georg Brandl21e99f42010-03-07 15:23:59 +00003938- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003939 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3940 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003941
Georg Brandl3ee81df2008-05-17 18:14:43 +00003942- Issue #1686386: Tuple's tp_repr did not take into account the
3943 possibility of having a self-referential tuple, which is possible
3944 from C code. Nor did object's tp_str consider that a type's tp_str
3945 could do something that could lead to an inifinite recursion.
3946 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3947 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003948
Georg Brandl3ee81df2008-05-17 18:14:43 +00003949- Issue #1164: It was possible to trigger deadlock when using the
3950 'print' statement to write to a file since the GIL was not released
3951 as needed. Now PyObject_Print() does the right thing along with
3952 various tp_print implementations of the built-in types and those in
3953 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003954
Georg Brandl3ee81df2008-05-17 18:14:43 +00003955- Issue #1147: Exceptions were directly allowing string exceptions in
3956 their throw() method even though string exceptions no longer
3957 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003958
Georg Brandl3ee81df2008-05-17 18:14:43 +00003959- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00003962- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003963 PyObject_Call() never calling back out to Python code to trigger
3964 recursion depth updates/checks. Required the creation of a static
3965 RuntimeError instance in case normalizing an exception put the
3966 recursion check value past its limit. Fixes crashers
3967 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003968
Georg Brandl3ee81df2008-05-17 18:14:43 +00003969- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00003982- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003983 __*__ attributes. (Some already existed, e.g., __doc__ and
3984 __name__.)

Georg Brandl3ee81df2008-05-17 18:14:43 +00003993 "except E as target:". This is to provide forwards compatibility
3994 with Python 3.0.

4014
Guido van Rossum143b5642007-03-23 04:58:42 +00004015- Bug #1683368: The object.__init__() and object.__new__() methods are
4016 now stricter in rejecting excess arguments. The only time when
4017 either allows excess arguments is when it is not overridden and the
4018 other one is. For backwards compatibility, when both are
4019 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004020 warning later). Also, type.__init__() insists on the same signature
4021 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004022
Georg Brandl3ee81df2008-05-17 18:14:43 +00004023- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4024 object to complex using its __complex__() method before falling back
4025 to the __float__() method. Therefore, the functions in the cmath
4026 module now can operate on objects that define a __complex__()
4027 method.

4044
Georg Brandl7b9c5552007-03-12 14:30:05 +00004045- Bug #1678647: write a newline after printing an exception in any
4046 case, even when converting the value to a string failed.
4047
Georg Brandl871f1bc2007-03-12 13:17:36 +00004048- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004049 its argument, if it exists. If not, it will work like before. This
4050 allows customizing the output of dir() in the presence of a
4051 __getattr__().

4060 parthensized forms. This means complex(repr(x)) now works instead of
4061 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004062
Georg Brandlaa2321b2007-03-07 00:40:28 +00004063- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004064 makes the filenames the warning module prints much more sensible
4065 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004066

Georg Brandl0fca97a2007-03-05 22:28:08 +00004078- Patch #1674228: when assigning a slice (old-style), check for the
4079 sq_ass_slice instead of the sq_slice slot.
4080
Georg Brandl3ee81df2008-05-17 18:14:43 +00004081- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00004707- unittest now verifies more of its assumptions. In particular,
4708 TestCase and TestSuite subclasses (not instances) are no longer
4709 accepted in TestSuite.addTest(). This should cause no
4710 incompatibility since it never made sense with ordinary subclasses
4711 -- the failure just occurred later, with a more cumbersome
4712 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004993- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4994 with RFC 3207 and forgets any knowledge obtained from the server not
4995 obtained from the TLS negotiation itself. Patch contributed by Bill
4996 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004997
Georg Brandl3ee81df2008-05-17 18:14:43 +00004998- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004999 that the SMTP.starttls() caller no longer needs to call ehlo()
5000 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00005001 does not claim to support starttls. Adds the
5002 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

5083 complex, tuple, list, dict, set, and frozenset. Formerly, it would
5084 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00005101 time so that opening a database previously created with the DB_DUP
5102 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5103 opens. Specifically: dictionary assignment to a DB object will
5104 replace all values for a given key when the database allows
5105 duplicate values. DB users should use DB.put(k, v) when they want
5106 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005107

5113 characters with ASCII value less than 32. Also, it correctly quotes
5114 dots only if they occur on a single line, as opposed to the previous
5115 behavior of quoting dots if they are the second character of any
5116 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00005117

Georg Brandl3ee81df2008-05-17 18:14:43 +00005441- Unified naming convention for free lists and their limits. All free
5442 lists in Object/ are named ``free_list``, the counter ``numfree``
5443 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
5444 #ifndef block.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005446- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5447 to ``PyTuple_SetItem``, it can be used to populate a brand new
5448 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00005449
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005450- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005452- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
5453 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
5454 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005455
5456- Patch #1720595: add T_BOOL to the range of structmember types.
5457
5458- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
5459 ``PyFloat_GetInfo()`` to the float API.
5460
Georg Brandl3ee81df2008-05-17 18:14:43 +00005461- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5462 of w# format code incorrectly truncated the length to an int, even
5463 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5464 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005465
Georg Brandl3ee81df2008-05-17 18:14:43 +00005466- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
5467 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005468
Georg Brandl3ee81df2008-05-17 18:14:43 +00005469- PEP 3123: Provide forward compatibility with Python 3.0, while
5470 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
5471 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005472
Georg Brandl3ee81df2008-05-17 18:14:43 +00005473- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
5474 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005475
5476- Patch #1733960: Allow T_LONGLONG to accept ints.
5477
5478- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
5479
Christian Heimes000a0742008-01-03 22:16:32 +00005480- Added a new API function ``PyImport_ImportModuleNoBlock``.
5481
Georg Brandl6caad7d2008-01-26 14:19:22 +00005482- Bug #1637022: Prefix AST symbols with _Py_.
5483
5484- Fix some leftovers from the conversion from int to Py_ssize_t
5485 (relevant to strings and sequences of more than 2**31 items).
5486
5487- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5488 outside of pystate.c and should not be necessary.
5489
Georg Brandl3ee81df2008-05-17 18:14:43 +00005490- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5491 absolute imports. In earlier versions they might have used relative
5492 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005493
Georg Brandl3ee81df2008-05-17 18:14:43 +00005494- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5495 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005496
Georg Brandl3ee81df2008-05-17 18:14:43 +00005497- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
5498 macro so it can be used as an expression.

5503
Georg Brandl3ee81df2008-05-17 18:14:43 +00005504- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
5505 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
5506 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
5507 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00005508
Georg Brandl3ee81df2008-05-17 18:14:43 +00005509- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
5510 _CRT_NONSTDC_NO_DEPRECATE.

Brett Cannon791d56f2007-05-31 19:40:42 +00005520- buildtools now raises a DeprecationWarning.
5521
Georg Brandl3ee81df2008-05-17 18:14:43 +00005522- Removed the macfs module. It had been deprecated since Python 2.5.
5523 This lead to the deprecation of macostools.touched() as it relied
5524 solely on macfs and was a no-op under OS X.
