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

Georg Brandlba83f822010-03-14 09:50:54 +0000251- Issue #7849: The utility ``test.test_support.check_warnings()`` verifies if
252 warnings are effectively raised. A new utility ``check_py3k_warnings()`` is
253 available.

Florent Xicluna985478d2010-03-06 18:52:52 +0000255- The four path modules (genericpath, macpath, ntpath, posixpath) share a
256 common TestCase for some tests: test_genericpath.CommonTest.
257
Georg Brandlba83f822010-03-14 09:50:54 +0000258- Print platform information when running the whole test suite, or using the

Georg Brandlba83f822010-03-14 09:50:54 +0000267- Issue #7712: test_support gained a new ``temp_cwd`` context manager which is
268 now also used by regrtest to run all the tests in a temporary directory. The
269 original CWD is saved in ``test.test_support.SAVEDCWD``. Thanks to Florent
270 Xicluna who helped with the patch.

287 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +0000288 library would return a bogus result; on Solaris, it was possible to crash the
289 interpreter. Patch by Stefan Krah.

Georg Brandlba83f822010-03-14 09:50:54 +0000302- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
303 and add the additional members returned in an OSVERSIONINFOEX structure. The
304 new members are service_pack_major, service_pack_minor, suite_mask, and
305 product_type.

Georg Brandlba83f822010-03-14 09:50:54 +0000307- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
308 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
309 returning NULL. The macro now returns a statically allocated empty string
310 instead.

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

342 XML processing instructions and comments. These raw characters are allowed
343 by the XML specification, and are necessary when outputting e.g. PHP code in
344 a processing instruction. Patch by Neil Muller.

Antoine Pitroud840e512010-02-04 20:20:18 +0000352- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +0000353 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +0000354 Also, raise ValueError rather than TypeError when an unknown TIPC address
355 type is specified. Patch by Brian Curtin.
356
Vinay Sajip28c382f2010-02-04 18:48:53 +0000357- logging: Implemented PEP 391.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000359- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +0000360 file position when calling `truncate()`. It would previously change the file
361 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000362 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
363
Benjamin Petersone06f7112010-01-28 02:15:02 +0000364- UserDict is now a new-style class.
365
Georg Brandlba83f822010-03-14 09:50:54 +0000366- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
367 class used to represent files stored inside an archive. The new
368 implementation is significantly faster and can be wrapped in a
369 ``io.BufferedReader`` object for more speedups. It also solves an issue
370 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
371 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +0000378- Issue #7773: Fix an UnboundLocalError in ``platform.linux_distribution()``
379 when the release file is empty.
Benjamin Petersona43f34c2010-01-25 03:31:13 +0000380
Georg Brandlba83f822010-03-14 09:50:54 +0000381- Issue #7748: Since unicode values are supported for some metadata options in
382 Distutils, the DistributionMetadata get_* methods will now return an utf-8
383 encoded string for them. This ensures that the upload and register commands
384 send the correct values to PyPI without any error.
Tarek Ziadéf14c7fc2010-01-24 00:33:32 +0000385
Georg Brandlba83f822010-03-14 09:50:54 +0000386- Issue #1670765: Prevent ``email.generator.Generator`` from re-wrapping
R. David Murrayed44dfa2010-01-16 05:15:17 +0000387 headers in multipart/signed MIME parts, which fixes one of the sources of

458Core and Builtins
459-----------------
460
Georg Brandlba83f822010-03-14 09:50:54 +0000461- The ``__complex__()`` method is now looked up on the class of instances to
462 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +0000463
Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000464- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
465 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
466
Mark Dickinson1b34d252010-01-01 17:27:30 +0000467- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000468 DeprecationWarning when passed a float argument where an integer was expected.
469 These functions and methods now raise TypeError instead. The majority of the
470 effects of this change are in the extension modules, but some core functions
471 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
472 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +0000485- Issue #1811: Improve accuracy and cross-platform consistency for true division
486 of integers: the result of a/b is now correctly rounded for ints a and b (at
487 least on IEEE 754 platforms), and in particular does not depend on the
488 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +0000489
Georg Brandlba83f822010-03-14 09:50:54 +0000490- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
491 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
492 in the subclass.

496
Georg Brandlba83f822010-03-14 09:50:54 +0000497 These executables now work properly with the arch(1) command: ``arch -ppc
498 python`` will start a universal binary version of python in PPC mode (unlike
499 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +0000655- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
656 decimal string that's guaranteed to round back to x under correct rounding
657 (with round-half-to-even rounding mode). Previously it gave a string based on
658 rounding x to 17 decimal digits. repr(x) for a complex number behaves
659 similarly. On platforms where the correctly-rounded strtod and dtoa code is
660 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000661
Georg Brandlba83f822010-03-14 09:50:54 +0000662- Issue #7117: On almost all platforms: float-to-string and string-to-float
663 conversions within Python are now correctly rounded. Places these conversions
664 occur include: str for floats and complex numbers; the float and complex
665 constructors; old-style and new-style numeric formatting; serialization and
666 deserialization of floats and complex numbers using marshal, pickle and json;
667 parsing of float and imaginary literals in Python code; Decimal-to-float
668 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000669
Georg Brandlba83f822010-03-14 09:50:54 +0000670 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
671 providing correctly-rounded strtod and dtoa C functions. This code is
672 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
673 the C compiler. There may be a small number of platforms on which correct
674 operation of this code cannot be guaranteed, so the code is not used: notably,
675 this applies to platforms where the C double format is not IEEE 754 binary64,
676 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
677 and Python's configure script is unable to determine how to change the FPU
678 precision. On these platforms conversions use the platform strtod and dtoa,
679 as before.

Georg Brandlba83f822010-03-14 09:50:54 +0000681- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
682 uses the correctly-rounded string <-> float conversions described above (when
683 available), and so produces correctly rounded results that will display nicely
684 under the float repr. There are two related small changes: (1) round now
685 accepts any class with an ``__index__()`` method for its second argument (but
686 no longer accepts floats for the second argument), and (2) an excessively
687 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
688 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +0000831 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
832 (2) parsing of strings representing infinities and nans was locale aware; and
833 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').
Eric Smitha985a3a2009-05-05 18:26:08 +0000834
Georg Brandlba83f822010-03-14 09:50:54 +0000835- Issue #5920: For ``float.__format__()``, change the behavior with the empty
836 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
837 but with at least one decimal point and with a default precision
838 of 12. Previously, the behavior the same but with a default precision of 6.
839 This more closely matches ``str()``, and reduces surprises when adding
840 alignment flags to the empty presentation type. This also affects the new
841 complex.__format__ in the same way.
842
843- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
844 classtype's, even if it was None. property now inserts the __doc__ into the

Georg Brandlba83f822010-03-14 09:50:54 +0000906 untrackable objects are not tracked by the garbage collector. This can reduce
907 the size of collections and therefore the garbage collection overhead on

915 internal representation of integers, for performance reasons. Base 2**30 is
916 enabled by default on 64-bit machines. Add --enable-big-digits option to
917 configure, which overrides the default. Add sys.long_info structseq to
918 provide information about the internal format.

980
Georg Brandlba83f822010-03-14 09:50:54 +0000981- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
982 existing .py counterpart, override the co_filename attributes of all code
983 objects if the original filename is obsolete (which can happen if the file has
984 been renamed, moved, or if it is accessed through different paths). Patch by
985 Ziga Seilnacht and Jean-Paul Calderone.
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000986
Georg Brandlba83f822010-03-14 09:50:54 +0000987- Issue #4075: Use ``OutputDebugStringW()`` in Py_FatalError.
Martin v. Löwis5344c992009-01-02 20:32:55 +0000988
Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +0000989- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
990 file with `str' filename on Windows.
991
Antoine Pitrouaa687902009-01-01 14:11:22 +0000992- Issue #3680: Reference cycles created through a dict, set or deque iterator
993 did not get collected.
994
Georg Brandlba83f822010-03-14 09:50:54 +0000995- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types where
996 the tp_hash and tp_dict slots are both NULL.
Nick Coghlan180e4002008-12-30 01:18:48 +0000997
Benjamin Peterson7af65562008-12-29 17:56:58 +0000998- Issue #4764: With io.open, IOError.filename is set when trying to open a
999 directory on POSIX systems.
1000
Benjamin Petersonfe231b02008-12-29 17:47:42 +00001001- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
1002 systems.
1003
Georg Brandl6425a2f2008-12-28 11:54:53 +00001004- Issue #4759: None is now allowed as the first argument of
Georg Brandlba83f822010-03-14 09:50:54 +00001005 ``bytearray.translate()``. It was always allowed for ``bytes.translate()``.
Georg Brandl6425a2f2008-12-28 11:54:53 +00001006
Skip Montanarof205c132008-12-23 03:30:15 +00001007- Added test case to ensure attempts to read from a file opened for writing
1008 fail.
1009
Georg Brandlba83f822010-03-14 09:50:54 +00001010- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always print
1011 elapsed times, not only when some objects are uncollectable/unreachable.
1012 Original patch by Neil Schemenauer.
Antoine Pitrou73c0e652008-12-17 22:46:54 +00001013
Mark Dickinson1a707982008-12-17 16:14:37 +00001014- Issue #3439: Add a bit_length method to int and long.
1015
Georg Brandlba83f822010-03-14 09:50:54 +00001016- Issue #2183: Simplify and optimize bytecode for list comprehensions. Original
1017 patch by Neal Norwitz.
Antoine Pitroud0c35152008-12-17 00:38:28 +00001018
Georg Brandlba83f822010-03-14 09:50:54 +00001019- Issue #4597: Fixed exception handling when the __exit__ function of a context
1020 manager returns a value that cannot be converted to a bool.
Amaury Forgeot d'Arcad9b5992008-12-10 23:22:49 +00001021
Georg Brandlba83f822010-03-14 09:50:54 +00001022- Issue #4597: Fixed several opcodes that weren't always propagating exceptions.
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +00001023
Georg Brandlba83f822010-03-14 09:50:54 +00001024- Issue #4445: Replace ``sizeof(PyStringObject)`` with
1025 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
1026 instances. On a typical machine this saves 3 bytes of memory (on average) per
1027 string allocation.
Mark Dickinson826f3fe2008-12-05 21:55:28 +00001028
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00001029- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1030 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1031 instead of throwing a MemoryError.
1032
Georg Brandlba83f822010-03-14 09:50:54 +00001033- Issue #3689: The list reversed iterator now supports __length_hint__ instead
1034 of __len__. Behavior now matches other reversed iterators.
Raymond Hettinger7989a4d2008-12-03 15:42:10 +00001035
Benjamin Petersonc078f922008-11-21 22:27:24 +00001036- Issue #4367: Python would segfault during compiling when the unicodedata
1037 module couldn't be imported and \N escapes were present.
1038
Georg Brandlba83f822010-03-14 09:50:54 +00001039- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
1040 file objects with closefd=False. The file descriptor is still kept open but
1041 the file object behaves like a closed file. The ``FileIO`` object also got a
1042 new readonly attribute ``closefd``.
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +00001043
Benjamin Peterson46cc6d12008-11-19 21:49:09 +00001044- Issue #4348: Some bytearray methods returned that didn't cause any change to
1045 the bytearray, returned the same bytearray instead of a copy.
1046
Georg Brandlba83f822010-03-14 09:50:54 +00001047- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.

Benjamin Peterson273c2332008-11-17 22:39:09 +00001049- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1050
Benjamin Peterson6624a9f2008-11-03 15:14:51 +00001051- Issue #4048: The parser module now correctly validates relative imports.
1052
Benjamin Petersondcee09d2008-10-31 02:16:05 +00001053- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1054 exec statement.
1055
Georg Brandlba83f822010-03-14 09:50:54 +00001056- Issue #4176: Fixed a crash when pickling an object which ``__reduce__`` method
1057 does not return iterators for the 4th and 5th items.
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +00001058
Benjamin Petersonbdca9422008-10-26 20:21:13 +00001059- Issue #4209: Enabling unicode_literals and the print_function in the same
1060 __future__ import didn't work.
1061
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00001062- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00001063 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00001064
Georg Brandlba83f822010-03-14 09:50:54 +00001065- On windows, ``os.chdir()`` given unicode was not working if
1066 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
1067 this code path is really executed because I cannot move to such directory on
1068 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00001069
Georg Brandlba83f822010-03-14 09:50:54 +00001070- Issue #4069: When ``set.remove(element)`` is used with a set element, the
1071 element is temporarily replaced with an equivalent frozenset. But the
1072 eventual KeyError would always report the empty ``frozenset()`` as the missing
1073 key. Now it correctly refers to the initial element.
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +00001074
Georg Brandlba83f822010-03-14 09:50:54 +00001075- Issue #4509: Various issues surrounding resize of bytearray objects to which
1076 there are buffer exports.
Antoine Pitrouae5bece2008-12-06 21:29:24 +00001077
Benjamin Peterson8d5934b2008-12-27 18:24:11 +00001078- Issue #4748: Lambda generators no longer return a value.

1081
Gregory P. Smithae91d092009-03-02 05:13:57 +00001082- The re.sub(), re.subn() and re.split() functions now accept a flags parameter.
1083
Georg Brandlba83f822010-03-14 09:50:54 +00001084- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with short
1085 file names.
Matthias Kloseedb5e1e2009-04-04 14:18:13 +00001086
Matthias Klose91a3b9e2009-04-05 21:19:13 +00001087- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1088 to avoid compiler warnings.
Matthias Klose0610e082009-04-05 12:43:08 +00001089
Gregory P. Smith2b3eb372009-04-05 23:48:26 +00001090- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
1091 returned them on 64bit platforms.
1092
Walter Dörwalded960ac2009-05-03 22:36:33 +00001093- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
1094 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1095 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1096 of using the replace error handler in PyUnicode_DecodeUTF8().
1097
Walter Dörwald726ba8e2009-05-06 14:32:35 +00001098- Issue #3739: The unicode-internal encoder now reports the number of characters
1099 consumed like any other encoder (instead of the number of bytes).
1100
Georg Brandlba83f822010-03-14 09:50:54 +00001101- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
1102 allocator will be automatically disabled when running under Valgrind. This
1103 gives improved memory leak detection when running under Valgrind, while taking
1104 advantage of pymalloc at other times.

1131 from the user's group and inherit from its container when the test is run.

Guilherme Polo7f146ab2009-06-21 17:22:50 +00002346- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
2347 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00002348 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
2349 the tests if DISPLAY is defined but can't be used.

Georg Brandlba83f822010-03-14 09:50:54 +00002354- Issue #5354: New test support function import_fresh_module() makes it easy to
2355 import both normal and optimised versions of modules. test_heapq and
2356 test_warnings have been adjusted to use it, tests for other modules with both
2357 C and Python implementations in the stdlib can be adjusted to use it over
2358 time.

Georg Brandlba83f822010-03-14 09:50:54 +00002366- regrtest no longer treats ImportError as equivalent to SkipTest. Imports that
2367 should cause a test to be skipped are now done using import_module from test
2368 support, which does the conversion.

2470
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002471- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2472 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2473 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2474 ``printf`` function, whereas PyString_FromFormat has an independent
2475 implementation and uses "%zd" on all platforms for size_t values.
2476 This makes a difference on win64, where ``printf`` needs "%Id" to display
2477 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00002479- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

2483 object; previously an int would be returned for small values. the __long__

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002494 was correctly parsed but parsing of subsequent arguments failed.
2495
Vinay Sajip35e3b032008-09-01 14:33:59 +00002496- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002497 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2498 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2499 when given a tuple of classes as second argument, were looking up
2500 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2501 type object.
2502
Neal Norwitz18aa3882008-08-24 05:04:52 +00002503- Fix crashes on memory allocation failure found with failmalloc.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002640What's New in Python 2.6 beta 3?
2641================================
2642
Barry Warsaw07a4a382008-08-21 01:15:08 +00002643*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002644
2645Core and Builtins
2646-----------------
2647
Guido van Rossumf8402962008-08-20 15:01:50 +00002648- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2649 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2650 extensions do not automatically benefit from the class attribute
2651 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2652 to their tp_flags field if they care. This is a backwards
2653 compatibility feature; in 3.0, all types will use the cache by
2654 default.
2655
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002656- Keyword arguments can now follow starred arguments. (``f(a, *args,
2657 keyword=23)`` is now valid syntax.)
2658
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002659- ctypes function pointers that are COM methods have a boolean True
2660 value again.
2661
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002662- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2663 by denying s# to parse objects that have a releasebuffer procedure,
2664 and introducing s*.
2665
Georg Brandl1e13ea92008-08-11 09:07:59 +00002666- Issue #3537: Fix an assertion failure when an empty but presized dict
2667 object was stored in the freelist.
2668
Mark Dickinsonb6467572008-08-04 21:30:09 +00002669- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2670 ValueError consistently across platforms.
2671
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002672- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2673 (64bit Unix, for example), unichr() would truncate its argument and return
2674 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2675
Neal Norwitze7d8be82008-07-31 17:17:14 +00002676- Apply security patches from Apple.
2677
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002678- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2679 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2680
Antoine Pitrou92f82162008-07-25 22:22:08 +00002681- Issue #1819: function calls with several named parameters are now on
2682 average 35% faster (as measured by pybench).
2683
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002684- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2685 the python debugger steps into a class statement: the free variables (local
2686 variables defined in an outer scope) would be deleted from the outer scope.
2687
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002688- Issue #2620: Overflow checking when allocating or reallocating memory
2689 was not always being done properly in some python types and extension
2690 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2691 all been updated to perform better checks and places in the code that
2692 would previously leak memory on the error path when such an allocation
2693 failed have been fixed.
2694
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002695Library
2696-------
2697
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002698- Issue #3612: Added some missing basic types in ctypes.wintypes.
2699
Benjamin Petersone977ad42008-08-20 01:42:01 +00002700- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2701 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2702
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002703- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2704 version reported by these tools does not necessarily follow the python
2705 version numbering scheme, so the module is less strict when parsing it.
2706
Nick Coghlanf70385a2008-08-18 12:42:46 +00002707- Issue #2235: Added Py3k warnings for types which will become unhashable
2708 under the stricter __hash__ inheritance rules in 3.0. Several types
2709 which did not meet the rules for hash invariants and were already
2710 unhashable in 3.0 have now been explicitly flagged as unhashable in
2711 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2712 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2713
Brett Cannon88f801d2008-08-18 00:46:22 +00002714- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2715 imported into the module but exposed as part of the module's API.
2716
Brett Cannon7b96f072008-08-18 00:41:11 +00002717- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2718
Brett Cannon46225e72008-08-18 00:36:52 +00002719- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
2720
Brett Cannon25c9d6a2008-08-17 22:10:11 +00002721- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2722
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002723- Issue #3575: Incremental decoder's decode function now takes bytearray
2724 by using 's*' instead of 't#'.
2725
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002726- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002727 fails unicode conversion on 2nd parameter. (windows only)
2728
Facundo Batista94f243a2008-08-17 03:38:39 +00002729- Issue 2464. urllib2 now supports a malformation in the URL received
2730 in a redirect.
2731
Brett Cannonabe423e2008-08-16 21:47:07 +00002732- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002733 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002734
Facundo Batistaeb90b782008-08-16 14:44:07 +00002735- Issue #2776: fixed small issue when handling an URL with double slash
2736 after a 302 response in the case of not going through a proxy.
2737
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002738- Issue #2676: in the email package, content-type parsing was hanging on
2739 pathological input because of quadratic or exponential behaviour of a
2740 regular expression.
2741
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002742- Issue #3476: binary buffered reading through the new "io" library is now
2743 thread-safe.
2744
Brett Cannonbf3157b2008-08-14 05:00:03 +00002745- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2746 since mimetools itself is deprecated. Because modules are cached, all
2747 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2748
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002749- Issue #3134: shutil referenced undefined WindowsError symbol.
2750
Robert Schuppenies14646332008-08-10 11:01:53 +00002751- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2752 menu entries were not deleted.
2753
Brett Cannon83e81842008-08-09 23:30:55 +00002754- Copied the implementation of reduce() to _functools.reduce() to have a
2755 version that did not raise a DeprecationWarning under -3.
2756
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002757- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2758 a MemoryError rather than silently stop the iteration.
2759
Guido van Rossum59ce9012008-08-09 14:55:34 +00002760- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2761 to _sre.compile() will now be rejected. This should not affect anybody
2762 since the re.compile() function never generates invalid re-bytecode.
2763
Skip Montanaroa032bf42008-08-08 22:52:51 +00002764- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2765 upon first access it can be automatically initialized from the csv file if
2766 it wasn't initialized during instantiation.
2767
Brett Cannon3aa2a492008-08-06 22:28:09 +00002768- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2769 the reload() built-in has been removed.
2770
Brett Cannon7e30b672008-08-04 21:52:25 +00002771- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002772 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00002773 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
2774 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
2775 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
2776 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
2777 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00002778
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00002779- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
2780 raised an AttributeError.
2781
Benjamin Peterson01a24322008-07-28 23:35:27 +00002782- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002783 asking for a specific length. This problem only affected files opened
2784 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002785
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00002786- Issue #3449: Update decimal module to use most recent specification
2787 (v. 1.68) and tests (v. 2.58) from IBM.
2788
Skip Montanarof9ac43f2008-07-27 00:50:41 +00002789- Issue 3437: Bug fix in robotparser parsing of Allow: lines.
2790

2797
2798- Issue #3303: Fix a crash in locale.strcoll() when calling it with
2799 invalid arguments.
2800
2801- Issue #3302: Fix several crashes when calling locale's gettext functions
2802 with None arguments.
2803
2804- Issue #3389: Allow resolving dotted names for handlers in logging
2805 configuration files.
2806
2807- Deprecate the sunaudio module for removal in Python 3.0.
2808
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002809- Issue #3394: zipfile.writestr sets external attributes when passed a
2810 file name rather than a ZipInfo instance, so files are extracted with
2811 mode 0600 rather than 000 under Unix.
2812
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002813- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2814 argument in python 2.5, this broke code that subclassed Popen to include its
2815 own poll method. Fixed my moving _deadstate to an _internal_poll method.
2816

2823-------------
2824
Nick Coghlan6e8fef02008-08-18 13:14:22 +00002825- Issue #2235: the C API function PyObject_HashNotImplemented and its
2826 interaction with the tp_hash slot (added in 2.6b2) are now documented
2827
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002828- Issue #643841: The language reference now provides more detailed
2829 coverage of the lookup process for special methods. The disclaimers
2830 regarding lack of coverage of new-style classes have also been
2831 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00002834What's New in Python 2.6 beta 2?
2835================================
2836
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002837*Release date: 17-Jul-2008*
2838
Raymond Hettingere3ae6552008-06-20 04:18:15 +00002839Core and Builtins
2840-----------------
2841
Georg Brandl3e483f62008-07-16 22:57:41 +00002842- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2843 its methods now allow for items objects that can be converted to
2844 an integer using operator.index().
2845
Mark Dickinson64b7e502008-07-16 09:40:03 +00002846- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2847 produced a ValueError instead of giving the correct float.
2848
Eric Smitha5fa5a22008-07-16 00:11:49 +00002849- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2850 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2851
Mark Dickinson7103aa42008-07-15 19:08:33 +00002852- Issue #3008: the float type has a new instance method 'float.hex'
2853 and a new class method 'float.fromhex' to convert floating-point
2854 numbers to and from hexadecimal strings, respectively.
2855
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002856- Issue #2235: __hash__ is once again inherited by default. To allow
2857 collections.Hashable to remain meaningful in the presence of the
2858 default hash implementation (object.__hash__), it is now possible
2859 to explicit block inheritance of hash by setting __hash__=None at
2860 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2861 level.
2862
Nick Coghlanb028f502008-07-13 14:52:36 +00002863- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2864 the parent module cannot be found while performing an absolute import.
2865 This means that an incorrectly defined __package__ attribute will
2866 now only prevent relative imports in that module rather than causing
2867 all imports from that module to fail.
2868
Nick Coghlan14ff9942008-07-08 14:21:42 +00002869- Issue #2517: Allow unicode messages in Exceptions again by correctly
2870 bypassing the instance dictionary when looking up __unicode__ on
2871 new-style classes.
2872
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002873- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2874 set to a custom object whose write() method happens to install
2875 another file in sys.stdout.
2876
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002877- Issue #3088: Corrected a race condition in classes derived from
2878 threading.local: the first member set by a thread could be saved in
2879 another thread's dictionary.
2880
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002881- Issue #3004: Minor change to slice.indices(): the start and stop
2882 arguments are now treated identically, making the behaviour easier
2883 to describe and understand. For example, slice(None, -10,
2884 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2885 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2886 10, -1).
2887
Georg Brandl278fc502008-07-19 12:46:12 +00002888- Issue #3219: Calling a function with repeated keyword arguments,
2889 f(a=2, a=23), would not cause a syntax error. This was a regression
2890 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002891
Georg Brandl278fc502008-07-19 12:46:12 +00002892- Issue #2862: Make int and float freelist management consistent with
2893 other freelists. Changes their CompactFreeList apis into
2894 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00002895

2897-------
2898
Thomas Heller57adf222008-08-14 19:10:48 +00002899- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2900 api functions without holding the GIL, which could lead to a fatal
2901 error when they failed.
2902
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002903- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00002911- Issue #3125: Remove copy_reg in multiprocessing and replace it with
2912 ForkingPickler.register() to resolve conflict with ctypes.
2913
Vinay Sajip51e65192008-07-18 09:01:10 +00002914- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

2917 a valid dlerror() message.
2918
Thomas Heller2bad6572008-07-15 17:19:50 +00002919- Issue #3258: Fixed a crash when a ctypes POINTER type to an
2920 incomplete structure was created.
2921
Brett Cannon3d0b9f02008-07-13 01:15:07 +00002922- Issue #3339: dummy_thread.acquire() should not return None.
2923
Raymond Hettingerb01713e2008-07-10 14:34:57 +00002924- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
2925
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002926- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00002927

3339 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00003340 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003341
3342 This is controlled by the configure argument ``--with-universal-archs``:
3343
3344 - ``--with-universal-archs=all``: install 4-way universal
3345
3346 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3347
3348 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3349
3350 This option should be used in combination with ``--enable-universalsdk=``.
3351
3352 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

3389 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00003390
Christian Heimese74c8f22008-04-19 02:23:57 +00003391- Added kill, terminate and send_signal(sig) to subprocess.Popen.
3392
Georg Brandl3ee81df2008-05-17 18:14:43 +00003393- Added phase(z) -> phi, polar(z) -> r, phi and rect(r, phi) -> z to
3394 the cmath module.
Christian Heimes6f341092008-04-18 23:13:07 +00003395

Georg Brandl3ee81df2008-05-17 18:14:43 +00003402- Issue #1631171: Re-implement the 'warnings' module in C (the
3403 original Python code has been kept as backup). This will allow for
3404 using the 'warning's machinery in such places as the parser where
3405 use of pure Python code is not possible. Both the ``showarning()``
3406 and ``formatwarning()`` gain an optional 'line' argument which is
3407 not called by default for backwards-compatibility reasons. Setting
3408 ``warnings.showwarning()`` to an implementation that lacks support
3409 for the ``line`` argument will raise a DeprecationWarning.

Neal Norwitz2b0bea52008-04-25 03:40:17 +00003431- Issue #2682: ctypes callback functions no longer contain a cyclic
Thomas Hellerbf027c42008-04-24 18:14:19 +00003432 reference to themselves.
3433
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00003434- The getpass module has been improved on Unix. It now uses /dev/tty
3435 by default and uses stderr instead of stdout. A GetPassWarning is
3436 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00003437

Georg Brandl3ee81df2008-05-17 18:14:43 +00003451- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00003452 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00003472- Issue #2550: The approach used by client/server code for obtaining
3473 ports to listen on in network-oriented tests has been refined in an
3474 effort to facilitate running multiple instances of the entire
3475 regression test suite in parallel without issue.
3476 test_support.bind_port() has been fixed such that it will always
3477 return a unique port -- which wasn't always the case with the
3478 previous implementation, especially if socket options had been set
3479 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3480 new implementation of bind_port() will actually raise an exception
3481 if it is passed an AF_INET/SOCK_STREAM socket with either the
3482 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3483 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3484 the socket it's been passed. This currently only applies to
3485 Windows. This option prevents any other sockets from binding to the
3486 host/port we've bound to, thus removing the possibility of the
3487 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3488 when a second SOCK_STREAM socket binds and accepts to a host/port
3489 that's already been bound by another socket. The optional preferred
3490 port parameter to bind_port() has been removed. Under no
3491 circumstances should tests be hard coding ports!
3492
3493 test_support.find_unused_port() has also been introduced, which will
3494 pass a temporary socket object to bind_port() in order to obtain an
3495 unused port. The temporary socket object is then closed and
3496 deleted, and the port is returned. This method should only be used
3497 for obtaining an unused port in order to pass to an external program
3498 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3499 a parameter to a server-oriented class that doesn't give you direct
3500 access to the underlying socket used.
3501
3502 Finally, test_support.HOST has been introduced, which should be used
3503 for the host argument of any relevant socket calls (i.e. bind and
3504 connect).

3779-----------------
3780
Fred Drakea8ee94b2008-03-01 02:45:07 +00003781- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003782 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00003784- Issue #2067: file.__exit__() now calls subclasses' close() method.
3785
3786- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003787
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003788- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003789 issue 215555 for a discussion.
3790
Eric Smitha73fbe72008-02-23 03:09:44 +00003791- Added the future_builtins module, which contains hex() and oct().
3792 These are the PEP 3127 version of these functions, designed to be
3793 compatible with the hex() and oct() builtins from Python 3.0. They
3794 differ slightly in their output formats from the existing, unchanged
3795 Python 2.6 builtins. The expected usage of the future_builtins
3796 module is:
3797 from future_builtins import hex, oct
3798
Eric Smith7ef40bf2008-02-20 23:34:22 +00003799- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3800 exponents for exponents with absolute value < 100. Follows C99
3801 standard. This is a change on Windows, which would use 3 digits.
3802 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3803 so that any alterations it does to the resulting string will be
3804 available in stringlib/formatter.h (for float.__format__).
3805
Eric Smith5a3c1352008-02-19 13:21:56 +00003806- Implemented PEP 3101, Advanced String Formatting. This adds a new
3807 builtin format(); a format() method for str and unicode; a
3808 __format__() method to object, str, unicode, int, long, float, and
3809 datetime; the class string.Formatter; and the C API
3810 PyObject_Format().
3811
Georg Brandl3ee81df2008-05-17 18:14:43 +00003812- Fixed several potential crashes, all caused by specially crafted
3813 __del__ methods exploiting objects in temporarily inconsistent
3814 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003815
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003816- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003817 prevent a possible crash: an Abstract Base Class would try to access
3818 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003819
Georg Brandl3ee81df2008-05-17 18:14:43 +00003820- Fixed repr() and str() of complex numbers with infinity or nan as
3821 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003822
Georg Brandl3ee81df2008-05-17 18:14:43 +00003823- Clear all free lists during a gc.collect() of the highest generation
3824 in order to allow pymalloc to free more arenas. Python may give back
3825 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003826
Georg Brandl3ee81df2008-05-17 18:14:43 +00003827- Issue #2045: Fix an infinite recursion triggered when printing a
3828 subclass of collections.defaultdict, if its default_factory is set
3829 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003830
Christian Heimesf75dbef2008-02-08 00:11:31 +00003831- Fixed a minor memory leak in dictobject.c. The content of the free
3832 list was not freed on interpreter shutdown.
3833
Georg Brandl21e99f42010-03-07 15:23:59 +00003834- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00003835 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003836
Georg Brandl3ee81df2008-05-17 18:14:43 +00003837- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3838 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003839 to compact the internal free lists of pre-allocted ints and floats.
3840
Georg Brandl3ee81df2008-05-17 18:14:43 +00003841- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3842 calls. Python expected the return type int but the fork familie
3843 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003844
Georg Brandl3ee81df2008-05-17 18:14:43 +00003845- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3846 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003847
Georg Brandl3ee81df2008-05-17 18:14:43 +00003848- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3849 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003850

3852 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003853
Georg Brandl3ee81df2008-05-17 18:14:43 +00003854- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3855 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003856
Georg Brandl3ee81df2008-05-17 18:14:43 +00003857- Patch #1473257: generator objects gain a gi_code attribute. This is
3858 the same object as the func_code attribute of the function that
3859 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003860
Georg Brandl3ee81df2008-05-17 18:14:43 +00003861- Issue #1920: "while 0" statements were completely removed by the
3862 compiler, even in the presence of an "else" clause, which is
3863 supposed to be run when the condition is false. Now the compiler
3864 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003865
Guido van Rossumeead05f2008-01-24 18:21:02 +00003866- A few crashers fixed: weakref_in_del.py (issue #1377858);
3867 loosing_dict_ref.py (issue #1303614, test67.py);
3868 borrowed_ref_[34].py (not in tracker).
3869
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003870- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003871 suppressed while an extension is loaded by calling SetErrorMode in
3872 dynload_win.c. The error is still reported properly.
3873
Georg Brandl3ee81df2008-05-17 18:14:43 +00003874- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003875 several extension methods and modules do not work without unicode
3876 support.
3877
Georg Brandl26543b12008-01-21 18:36:51 +00003878- Issue #1882: when compiling code from a string, encoding cookies in the
3879 second line of code were not always recognized correctly.
3880
Georg Brandl14404b62008-01-19 19:27:05 +00003881- Issue #1679: "0x" was taken as a valid integer literal.
3882
Georg Brandl6caad7d2008-01-26 14:19:22 +00003883- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003884 added.
3885
Christian Heimesc94e2b52008-01-14 04:13:37 +00003886- sys.float_info / PyFloat_GetInfo: The floating point information
3887 object was converted from a dict to a specialized structseq object.
3888
Georg Brandl3ee81df2008-05-17 18:14:43 +00003889- Patch #1816: Added sys.flags structseq. It exposes the status of
3890 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003891
Georg Brandl3ee81df2008-05-17 18:14:43 +00003892- Objects/structseq.c: Implemented new structseq representation. The
3893 patch makes structseqs (e.g. the return value of os.stat) more
3894 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003895
Georg Brandl3ee81df2008-05-17 18:14:43 +00003896- Patch #1700288: added a type attribute cache that caches method
3897 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003898
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003899- Bug #1776: __import__() no longer accepts filenames on any platform.
3900 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003901
Georg Brandlaed6c662008-01-07 17:25:53 +00003902- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3903
Georg Brandl3ee81df2008-05-17 18:14:43 +00003904- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3905 envvar and sys.dont_write_bytecode attribute. All these can be set
3906 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003907
Georg Brandl3ee81df2008-05-17 18:14:43 +00003908- Improve some exception messages when Windows fails to load an
3909 extension module. Now we get for example '%1 is not a valid Win32
3910 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003911
Georg Brandl3ee81df2008-05-17 18:14:43 +00003912- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003914- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3915 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003916
Christian Heimes0a8143f2007-12-18 23:22:54 +00003917- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003918 and INF. float("nan"), float("inf") and float("-inf") now work on
3919 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003920
Georg Brandl3ee81df2008-05-17 18:14:43 +00003921- Compiler now generates simpler and faster code for dictionary
3922 literals. The oparg for BUILD_MAP now indicates an estimated
3923 dictionary size. There is a new opcode, STORE_MAP, for adding
3924 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003958- Issue #1265: Fix a problem with sys.settrace, if the tracing
3959 function uses a generator expression when at the same time the
3960 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003961
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003962- sets and frozensets now have an isdisjoint() method.
3963
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003964- optimize the performance of builtin.sum().

3967
Georg Brandl21e99f42010-03-07 15:23:59 +00003968- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00003969 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3970 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003971
Georg Brandl3ee81df2008-05-17 18:14:43 +00003972- Issue #1686386: Tuple's tp_repr did not take into account the
3973 possibility of having a self-referential tuple, which is possible
3974 from C code. Nor did object's tp_str consider that a type's tp_str
3975 could do something that could lead to an inifinite recursion.
3976 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3977 issues.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003979- Issue #1164: It was possible to trigger deadlock when using the
3980 'print' statement to write to a file since the GIL was not released
3981 as needed. Now PyObject_Print() does the right thing along with
3982 various tp_print implementations of the built-in types and those in

3987 allowed.

Brett Cannon1e534b52007-09-07 04:18:30 +00003992- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003993 PyObject_Call() never calling back out to Python code to trigger
3994 recursion depth updates/checks. Required the creation of a static
3995 RuntimeError instance in case normalizing an exception put the
3996 recursion check value past its limit. Fixes crashers
3997 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00004012- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004013 __*__ attributes. (Some already existed, e.g., __doc__ and
4014 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004015
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004016- Add -3 option to the interpreter to warn about features that are

4020 calls.
4021
Collin Winter62903052007-05-18 23:11:24 +00004022- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004023 "except E as target:". This is to provide forwards compatibility
4024 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004025
Brett Cannon229cee22007-05-05 01:34:02 +00004026- Deprecate BaseException.message as per PEP 352.
4027
Georg Brandl3ee81df2008-05-17 18:14:43 +00004028- Issue #1303614: don't expose object's __dict__ when the dict is

Vinay Sajip8549ce32007-05-06 17:53:37 +00004031- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004032 setting a plain string, ie don't expand to single letter identifiers.
4033
Raymond Hettinger13936692007-04-11 18:40:58 +00004034- Request #1191699: Slices can now be pickled.
4035
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004036- Request #1193128: str.translate() now allows a None argument for
4037 translations that only remove characters without re-mapping the
4038 remaining characters.
4039
Georg Brandl5cb76c12007-03-21 09:00:39 +00004040- Patch #1682205: a TypeError while unpacking an iterable is no longer

4044
Guido van Rossum143b5642007-03-23 04:58:42 +00004045- Bug #1683368: The object.__init__() and object.__new__() methods are
4046 now stricter in rejecting excess arguments. The only time when
4047 either allows excess arguments is when it is not overridden and the
4048 other one is. For backwards compatibility, when both are
4049 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004050 warning later). Also, type.__init__() insists on the same signature
4051 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004052
Georg Brandl3ee81df2008-05-17 18:14:43 +00004053- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4054 object to complex using its __complex__() method before falling back
4055 to the __float__() method. Therefore, the functions in the cmath
4056 module now can operate on objects that define a __complex__()
4057 method.

4074
Georg Brandl7b9c5552007-03-12 14:30:05 +00004075- Bug #1678647: write a newline after printing an exception in any
4076 case, even when converting the value to a string failed.
4077
Georg Brandl871f1bc2007-03-12 13:17:36 +00004078- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004079 its argument, if it exists. If not, it will work like before. This
4080 allows customizing the output of dir() in the presence of a
4081 __getattr__().

4090 parthensized forms. This means complex(repr(x)) now works instead of
4091 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004092
Georg Brandlaa2321b2007-03-07 00:40:28 +00004093- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004094 makes the filenames the warning module prints much more sensible
4095 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004096

Georg Brandl0fca97a2007-03-05 22:28:08 +00004108- Patch #1674228: when assigning a slice (old-style), check for the
4109 sq_ass_slice instead of the sq_slice slot.
4110
Georg Brandl3ee81df2008-05-17 18:14:43 +00004111- When printing an unraisable error, don't print exceptions. before

4722 Python would crash instead of raising an error.
4723
Thomas Hellerc2f77252007-03-09 19:21:28 +00004724- Bug #1646630: ctypes.string_at(buf, 0) and ctypes.wstring_at(buf, 0)
4725 returned string up to the first NUL character.

4736
Georg Brandl3ee81df2008-05-17 18:14:43 +00004737- unittest now verifies more of its assumptions. In particular,
4738 TestCase and TestSuite subclasses (not instances) are no longer
4739 accepted in TestSuite.addTest(). This should cause no
4740 incompatibility since it never made sense with ordinary subclasses
4741 -- the failure just occurred later, with a more cumbersome
4742 exception.

Gregory P. Smith2b3ba582008-01-17 08:03:17 +00005027
Georg Brandl3ee81df2008-05-17 18:14:43 +00005028- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005029 that the SMTP.starttls() caller no longer needs to call ehlo()
5030 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00005031 does not claim to support starttls. Adds the
5032 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +00005131 time so that opening a database previously created with the DB_DUP
5132 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5133 opens. Specifically: dictionary assignment to a DB object will
5134 replace all values for a given key when the database allows
5135 duplicate values. DB users should use DB.put(k, v) when they want
5136 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005137

5143 characters with ASCII value less than 32. Also, it correctly quotes
5144 dots only if they occur on a single line, as opposed to the previous
5145 behavior of quoting dots if they are the second character of any
5146 line.

5469-----
5470
Georg Brandl3ee81df2008-05-17 18:14:43 +00005471- Unified naming convention for free lists and their limits. All free
5472 lists in Object/ are named ``free_list``, the counter ``numfree``
5473 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
5474 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00005475
Georg Brandl3ee81df2008-05-17 18:14:43 +00005476- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5477 to ``PyTuple_SetItem``, it can be used to populate a brand new
5478 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00005479
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005480- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005482- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
5483 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
5484 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005485
5486- Patch #1720595: add T_BOOL to the range of structmember types.
5487
5488- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
5489 ``PyFloat_GetInfo()`` to the float API.
5490
Georg Brandl3ee81df2008-05-17 18:14:43 +00005491- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5492 of w# format code incorrectly truncated the length to an int, even
5493 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5494 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005495
Georg Brandl3ee81df2008-05-17 18:14:43 +00005496- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
5497 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005498
Georg Brandl3ee81df2008-05-17 18:14:43 +00005499- PEP 3123: Provide forward compatibility with Python 3.0, while
5500 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
5501 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005502
Georg Brandl3ee81df2008-05-17 18:14:43 +00005503- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
5504 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005505
5506- Patch #1733960: Allow T_LONGLONG to accept ints.
5507
5508- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
5509

5513
5514- Fix some leftovers from the conversion from int to Py_ssize_t
5515 (relevant to strings and sequences of more than 2**31 items).
5516
5517- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5518 outside of pystate.c and should not be necessary.
5519
Georg Brandl3ee81df2008-05-17 18:14:43 +00005520- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5521 absolute imports. In earlier versions they might have used relative
5522 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005523
Georg Brandl3ee81df2008-05-17 18:14:43 +00005524- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5525 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005526
Georg Brandl3ee81df2008-05-17 18:14:43 +00005527- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
5528 macro so it can be used as an expression.

5533
Georg Brandl3ee81df2008-05-17 18:14:43 +00005534- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
5535 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
5536 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
5537 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00005538
Georg Brandl3ee81df2008-05-17 18:14:43 +00005539- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Georg Brandl3ee81df2008-05-17 18:14:43 +00005552- Removed the macfs module. It had been deprecated since Python 2.5.
5553 This lead to the deprecation of macostools.touched() as it relied
5554 solely on macfs and was a no-op under OS X.
