257 start byte and the continuation byte(s) are now considered invalid, instead
258 of the number of bytes specified by the start byte.
259 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
260 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte

272 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

R. David Murray1a14d3d2010-04-12 16:35:19 +0000569- Issue #7585: difflib context and unified diffs now place a tab between
Georg Brandlfee0f442010-05-22 21:26:21 +0000570 filename and date, conforming to the 'standards' they were originally designed
571 to follow. This improves compatibility with patch tools.

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +0000617 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
618 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
619 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

639Core and Builtins
640-----------------
641
Philip Jenveyaebbaeb2010-04-06 23:24:45 +0000642- Issue #7301: Add environment variable $PYTHONWARNINGS.
643
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +0000644- Issue #8329: Don't return the same lists from select.select when no fds are
645 changed.
646
Georg Brandlfee0f442010-05-22 21:26:21 +0000647- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +0000648 on 64-bit machines. The shift count for either left or right shift is
649 permitted to be up to sys.maxsize.
650
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +0000651- Ensure that tokenization of identifiers is not affected by locale.
652
Georg Brandlfee0f442010-05-22 21:26:21 +0000653- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.

Benjamin Peterson1c7c11e2010-04-03 01:28:57 +0000655- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
656
Georg Brandlfee0f442010-05-22 21:26:21 +0000657- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
658 with a non-empty format string. This is an effort to future-proof user
659 code. If a derived class does not currently implement __format__ but later
660 adds its own __format__, it would most likely break user code that had
661 supplied a format string. This will be changed to a DeprecationWaring in
662 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +0000663
Antoine Pitroua57df2c2010-03-31 21:32:15 +0000664- Issue #8268: Old-style classes (not just instances) now support weak
665 references.

688
Antoine Pitrouf9de5342010-04-05 21:35:07 +0000689- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +0000690 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
691 `ssl.OPENSSL_VERSION_NUMBER`.

694
Georg Brandlfee0f442010-05-22 21:26:21 +0000695- Issue #8257: The Decimal construct now accepts a float instance directly,
696 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +0000697
698 >>> Decimal(1.1)
699 Decimal('1.100000000000000088817841970012523233890533447265625')
700
Raymond Hettinger34c35b22010-04-03 10:22:00 +0000701- collections.Counter() now supports a subtract() method.
702
Georg Brandlfee0f442010-05-22 21:26:21 +0000703- The functools module now has a total_ordering() class decorator to simplify
704 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +0000705
Georg Brandlfee0f442010-05-22 21:26:21 +0000706- The functools module also adds cmp_to_key() as a tool to transition old-style
707 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +0000708
Georg Brandlfee0f442010-05-22 21:26:21 +0000709- Issue #8294: The Fraction constructor now accepts Decimal and float instances
710 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +0000711
Georg Brandlfee0f442010-05-22 21:26:21 +0000712- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
713 InvalidOperation instead of returning False. (Comparisons involving a quiet
714 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
715 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +0000716
Georg Brandlfee0f442010-05-22 21:26:21 +0000717- Issue #2531: Comparison operations between floats and Decimal instances now
718 return a result based on the numeric values of the operands; previously they
719 returned an arbitrary result based on the relative ordering of id(float) and
720 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +0000721
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000722- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +0000723 argument `-` which tells it to read files to compile from stdin. Each line is
724 read on demand and the named file is compiled immediately. (Original patch by
725 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000726
Georg Brandlfee0f442010-05-22 21:26:21 +0000727- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +0000730- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
731 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +0000732 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/

Georg Brandlfee0f442010-05-22 21:26:21 +0000734- Comparisons using one of <, <=, >, >= between a complex instance and a
735 Fractions instance now raise TypeError instead of returning True/False. This
736 makes Fraction <=> complex comparisons consistent with int <=> complex, float
737 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +0000738
Michael Foorde6410c52010-03-29 20:04:23 +0000739- Addition of ``WeakSet`` to the ``weakref`` module.

747
Antoine Pitrou513d9ae2010-03-22 19:59:46 +0000748- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +0000749 didn't support chflags() (for example ZFS under FreeBSD). The error is now
750 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +0000751
Florent Xicluna9e7a4c92010-03-22 16:07:38 +0000752- Issue #7703: ctypes supports both buffer() and memoryview(). The former is

Vinay Sajipecfa08f2010-03-12 09:16:10 +0000792- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +0000793 for ``TimedRotatingFileHandler`` by using the modification time of an existing
794 log file to compute the next rollover time. If the log file does not exist,
795 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +0000796

837 integer format code, struct.pack first attempts to convert the non-integer
838 using its __index__ method. If that method is non-existent or raises
839 TypeError it goes on to try the __int__ method, as described below.

Georg Brandlba83f822010-03-14 09:50:54 +0000841- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
842 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
843 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +0000844 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
845 inconsistent: __int__ was used for some integer codes but not for others, and
846 the set of integer codes for which it was used differed between native packing
847 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00001054- Issue #7712: test_support gained a new ``temp_cwd`` context manager which is
1055 now also used by regrtest to run all the tests in a temporary directory. The
1056 original CWD is saved in ``test.test_support.SAVEDCWD``. Thanks to Florent
1057 Xicluna who helped with the patch.

1074 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +00001075 library would return a bogus result; on Solaris, it was possible to crash the
1076 interpreter. Patch by Stefan Krah.

Georg Brandlba83f822010-03-14 09:50:54 +00001089- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
1090 and add the additional members returned in an OSVERSIONINFOEX structure. The
1091 new members are service_pack_major, service_pack_minor, suite_mask, and

Georg Brandlba83f822010-03-14 09:50:54 +00001094- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
1095 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
1096 returning NULL. The macro now returns a statically allocated empty string
1097 instead.

1107 strings,
1108 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
1109 numeric strings corresponding to subnormal values,
1110 (3) a memory leak for some values large enough to cause overflow, and
1111 (4) a number of flaws that could lead to incorrectly rounded results.

Antoine Pitroud840e512010-02-04 20:20:18 +00001142- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00001143 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00001144 Also, raise ValueError rather than TypeError when an unknown TIPC address
1145 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001149- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00001150 file position when calling `truncate()`. It would previously change the file
1151 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001152 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
1153
Georg Brandlba83f822010-03-14 09:50:54 +00001154- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
1155 class used to represent files stored inside an archive. The new
1156 implementation is significantly faster and can be wrapped in a
1157 ``io.BufferedReader`` object for more speedups. It also solves an issue
1158 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
1159 Patch by Nir Aides.

Benjamin Petersona43f34c2010-01-25 03:31:13 +00001168
Georg Brandlba83f822010-03-14 09:50:54 +00001169- Issue #7748: Since unicode values are supported for some metadata options in
1170 Distutils, the DistributionMetadata get_* methods will now return an utf-8
1171 encoded string for them. This ensures that the upload and register commands
1172 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00001249- The ``__complex__()`` method is now looked up on the class of instances to
1250 make it consistent with other special methods.

1254
Mark Dickinson1b34d252010-01-01 17:27:30 +00001255- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001256 DeprecationWarning when passed a float argument where an integer was expected.
1257 These functions and methods now raise TypeError instead. The majority of the
1258 effects of this change are in the extension modules, but some core functions
1259 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1260 and many unicode/str methods.

1274 of integers: the result of a/b is now correctly rounded for ints a and b (at
1275 least on IEEE 754 platforms), and in particular does not depend on the
1276 internal representation of a long.

1284
Georg Brandlba83f822010-03-14 09:50:54 +00001285 These executables now work properly with the arch(1) command: ``arch -ppc
1286 python`` will start a universal binary version of python in PPC mode (unlike

1427 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001428
Georg Brandlba83f822010-03-14 09:50:54 +00001429- Remove switch from "%f" formatting to "%g" formatting for floats larger than
1430 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00001431

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00001442
Georg Brandlba83f822010-03-14 09:50:54 +00001443- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1444 decimal string that's guaranteed to round back to x under correct rounding
1445 (with round-half-to-even rounding mode). Previously it gave a string based on
1446 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1447 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1448 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001449
Georg Brandlba83f822010-03-14 09:50:54 +00001450- Issue #7117: On almost all platforms: float-to-string and string-to-float
1451 conversions within Python are now correctly rounded. Places these conversions
1452 occur include: str for floats and complex numbers; the float and complex
1453 constructors; old-style and new-style numeric formatting; serialization and
1454 deserialization of floats and complex numbers using marshal, pickle and json;
1455 parsing of float and imaginary literals in Python code; Decimal-to-float
1456 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001457
Georg Brandlba83f822010-03-14 09:50:54 +00001458 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1459 providing correctly-rounded strtod and dtoa C functions. This code is
1460 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1461 the C compiler. There may be a small number of platforms on which correct
1462 operation of this code cannot be guaranteed, so the code is not used: notably,
1463 this applies to platforms where the C double format is not IEEE 754 binary64,
1464 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1465 and Python's configure script is unable to determine how to change the FPU
1466 precision. On these platforms conversions use the platform strtod and dtoa,
1467 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001468
Georg Brandlba83f822010-03-14 09:50:54 +00001469- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1470 uses the correctly-rounded string <-> float conversions described above (when
1471 available), and so produces correctly rounded results that will display nicely
1472 under the float repr. There are two related small changes: (1) round now
1473 accepts any class with an ``__index__()`` method for its second argument (but
1474 no longer accepts floats for the second argument), and (2) an excessively
1475 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1476 raises an exception.

1625 but with at least one decimal point and with a default precision
1626 of 12. Previously, the behavior the same but with a default precision of 6.
1627 This more closely matches ``str()``, and reduces surprises when adding

1629 complex.__format__ in the same way.

Georg Brandlba83f822010-03-14 09:50:54 +00001769- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
1770 existing .py counterpart, override the co_filename attributes of all code
1771 objects if the original filename is obsolete (which can happen if the file has
1772 been renamed, moved, or if it is accessed through different paths). Patch by

1813 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
1814 instances. On a typical machine this saves 3 bytes of memory (on average) per

1820
Georg Brandlba83f822010-03-14 09:50:54 +00001821- Issue #3689: The list reversed iterator now supports __length_hint__ instead

1826
Georg Brandlba83f822010-03-14 09:50:54 +00001827- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
1828 file objects with closefd=False. The file descriptor is still kept open but
1829 the file object behaves like a closed file. The ``FileIO`` object also got a
1830 new readonly attribute ``closefd``.

1849
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00001850- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00001851 because it is a reserved word in 3.x.

Georg Brandlba83f822010-03-14 09:50:54 +00001853- On windows, ``os.chdir()`` given unicode was not working if
1854 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
1855 this code path is really executed because I cannot move to such directory on
1856 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00001858- Issue #4069: When ``set.remove(element)`` is used with a set element, the
1859 element is temporarily replaced with an equivalent frozenset. But the
1860 eventual KeyError would always report the empty ``frozenset()`` as the missing
1861 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00001881- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
1882 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1883 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1884 of using the replace error handler in PyUnicode_DecodeUTF8().
1885
Walter Dörwald726ba8e2009-05-06 14:32:35 +00001886- Issue #3739: The unicode-internal encoder now reports the number of characters

1888
Georg Brandlba83f822010-03-14 09:50:54 +00001889- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
1890 allocator will be automatically disabled when running under Valgrind. This
1891 gives improved memory leak detection when running under Valgrind, while taking
1892 advantage of pymalloc at other times.

3123 __all__ attribute, rather than using a hardcoded and incomplete list.
3124
R. David Murray14dcd432009-10-14 13:58:07 +00003125- Issue #7058: Added save/restore for things like sys.argv and cwd to
3126 runtest_inner in regrtest, with warnings if the called test modifies them,
3127 and a new section in the summary report at the end.

3132 off the trailing 0 in the version number.
3133
Guilherme Polo7f146ab2009-06-21 17:22:50 +00003134- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
3135 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00003136 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
3137 the tests if DISPLAY is defined but can't be used.

Antoine Pitrou4698d992009-05-31 14:20:14 +00003139- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
3140 regression tests in parallel, shortening the total runtime.
3141
Georg Brandlba83f822010-03-14 09:50:54 +00003142- Issue #5354: New test support function import_fresh_module() makes it easy to
3143 import both normal and optimised versions of modules. test_heapq and
3144 test_warnings have been adjusted to use it, tests for other modules with both
3145 C and Python implementations in the stdlib can be adjusted to use it over
3146 time.

3153
Georg Brandlba83f822010-03-14 09:50:54 +00003154- regrtest no longer treats ImportError as equivalent to SkipTest. Imports that
3155 should cause a test to be skipped are now done using import_module from test
3156 support, which does the conversion.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00003257- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
3258
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003259- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3260 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3261 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3262 ``printf`` function, whereas PyString_FromFormat has an independent
3263 implementation and uses "%zd" on all platforms for size_t values.
3264 This makes a difference on win64, where ``printf`` needs "%Id" to display
3265 64bit values.
3266
Benjamin Peterson97179b02008-09-09 20:55:01 +00003267- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

3271 object; previously an int would be returned for small values. the __long__
3272 method is allowed to return either an int or a long, but the behaviour of
3273 float objects should not change to respect backward compatibility.
3274
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00003275- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +00003281 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003282 was correctly parsed but parsing of subsequent arguments failed.
3283
Vinay Sajip35e3b032008-09-01 14:33:59 +00003284- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003285 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3286 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3287 when given a tuple of classes as second argument, were looking up
3288 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3289 type object.
3290
Neal Norwitz18aa3882008-08-24 05:04:52 +00003291- Fix crashes on memory allocation failure found with failmalloc.

Martin v. Löwisab0b29b2008-09-13 08:11:57 +00003417- Issue #3833: Use a different upgrade code for Win64 installers.
3418
Martin v. Löwis3f5fda82008-09-08 13:50:10 +00003419- Issue #2271: Set SecureCustomProperties so that installation will properly
3420 use the TARGETDIR even for unprivileged users.
3421
Martin v. Löwis67543a92008-09-08 12:02:45 +00003422- Allow passing the MSI file name to merge.py.
3423
Vinay Sajip844f7412008-09-09 13:42:08 +00003424- Issue #3758: Rename the 'check' target to 'patchcheck' so as to not clash
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00003425 with GNU build target guidelines.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003428What's New in Python 2.6 beta 3?
3429================================
3430
Barry Warsaw07a4a382008-08-21 01:15:08 +00003431*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003432
3433Core and Builtins
3434-----------------
3435
Guido van Rossumf8402962008-08-20 15:01:50 +00003436- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3437 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3438 extensions do not automatically benefit from the class attribute
3439 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3440 to their tp_flags field if they care. This is a backwards
3441 compatibility feature; in 3.0, all types will use the cache by
3442 default.
3443
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003444- Keyword arguments can now follow starred arguments. (``f(a, *args,
3445 keyword=23)`` is now valid syntax.)
3446
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003447- ctypes function pointers that are COM methods have a boolean True
3448 value again.
3449
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003450- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3451 by denying s# to parse objects that have a releasebuffer procedure,
3452 and introducing s*.
3453
Georg Brandl1e13ea92008-08-11 09:07:59 +00003454- Issue #3537: Fix an assertion failure when an empty but presized dict
3455 object was stored in the freelist.
3456
Mark Dickinsonb6467572008-08-04 21:30:09 +00003457- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3458 ValueError consistently across platforms.
3459
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003460- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3461 (64bit Unix, for example), unichr() would truncate its argument and return
3462 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3463
Neal Norwitze7d8be82008-07-31 17:17:14 +00003464- Apply security patches from Apple.
3465
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003466- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3467 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3468
Antoine Pitrou92f82162008-07-25 22:22:08 +00003469- Issue #1819: function calls with several named parameters are now on
3470 average 35% faster (as measured by pybench).
3471
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003472- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3473 the python debugger steps into a class statement: the free variables (local
3474 variables defined in an outer scope) would be deleted from the outer scope.
3475
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003476- Issue #2620: Overflow checking when allocating or reallocating memory
3477 was not always being done properly in some python types and extension
3478 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3479 all been updated to perform better checks and places in the code that
3480 would previously leak memory on the error path when such an allocation
3481 failed have been fixed.
3482
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003483Library
3484-------
3485
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003486- Issue #3612: Added some missing basic types in ctypes.wintypes.
3487
Benjamin Petersone977ad42008-08-20 01:42:01 +00003488- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3489 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3490
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003491- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3492 version reported by these tools does not necessarily follow the python
3493 version numbering scheme, so the module is less strict when parsing it.
3494
Nick Coghlanf70385a2008-08-18 12:42:46 +00003495- Issue #2235: Added Py3k warnings for types which will become unhashable
3496 under the stricter __hash__ inheritance rules in 3.0. Several types
3497 which did not meet the rules for hash invariants and were already
3498 unhashable in 3.0 have now been explicitly flagged as unhashable in
3499 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3500 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3501
Brett Cannon88f801d2008-08-18 00:46:22 +00003502- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3503 imported into the module but exposed as part of the module's API.
3504
Brett Cannon7b96f072008-08-18 00:41:11 +00003505- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3506
Brett Cannon46225e72008-08-18 00:36:52 +00003507- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
3508
Brett Cannon25c9d6a2008-08-17 22:10:11 +00003509- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
3510
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003511- Issue #3575: Incremental decoder's decode function now takes bytearray
3512 by using 's*' instead of 't#'.
3513
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003514- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003515 fails unicode conversion on 2nd parameter. (windows only)
3516
Facundo Batista94f243a2008-08-17 03:38:39 +00003517- Issue 2464. urllib2 now supports a malformation in the URL received
3518 in a redirect.
3519
Brett Cannonabe423e2008-08-16 21:47:07 +00003520- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003521 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003522
Facundo Batistaeb90b782008-08-16 14:44:07 +00003523- Issue #2776: fixed small issue when handling an URL with double slash
3524 after a 302 response in the case of not going through a proxy.
3525
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003526- Issue #2676: in the email package, content-type parsing was hanging on
3527 pathological input because of quadratic or exponential behaviour of a
3528 regular expression.
3529
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003530- Issue #3476: binary buffered reading through the new "io" library is now
3531 thread-safe.
3532
Brett Cannonbf3157b2008-08-14 05:00:03 +00003533- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3534 since mimetools itself is deprecated. Because modules are cached, all
3535 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3536
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003537- Issue #3134: shutil referenced undefined WindowsError symbol.
3538
Robert Schuppenies14646332008-08-10 11:01:53 +00003539- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3540 menu entries were not deleted.
3541
Brett Cannon83e81842008-08-09 23:30:55 +00003542- Copied the implementation of reduce() to _functools.reduce() to have a
3543 version that did not raise a DeprecationWarning under -3.
3544
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003545- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3546 a MemoryError rather than silently stop the iteration.
3547
Guido van Rossum59ce9012008-08-09 14:55:34 +00003548- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3549 to _sre.compile() will now be rejected. This should not affect anybody
3550 since the re.compile() function never generates invalid re-bytecode.
3551
Skip Montanaroa032bf42008-08-08 22:52:51 +00003552- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3553 upon first access it can be automatically initialized from the csv file if
3554 it wasn't initialized during instantiation.
3555
Brett Cannon3aa2a492008-08-06 22:28:09 +00003556- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3557 the reload() built-in has been removed.
3558
Brett Cannon7e30b672008-08-04 21:52:25 +00003559- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003560 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00003561 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
3562 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
3563 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
3564 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
3565 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00003566
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00003567- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
3568 raised an AttributeError.
3569
Benjamin Peterson01a24322008-07-28 23:35:27 +00003570- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00003571 asking for a specific length. This problem only affected files opened
3572 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003573
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00003574- Issue #3449: Update decimal module to use most recent specification
3575 (v. 1.68) and tests (v. 2.58) from IBM.
3576
Skip Montanarof9ac43f2008-07-27 00:50:41 +00003577- Issue 3437: Bug fix in robotparser parsing of Allow: lines.
3578
Raymond Hettinger8c664e82008-07-25 18:43:33 +00003579- Issue 1592: Improve error reporting when operations are attempted
3580 on a closed shelf.

3583
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003584- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
3585
3586- Issue #3303: Fix a crash in locale.strcoll() when calling it with
3587 invalid arguments.
3588
3589- Issue #3302: Fix several crashes when calling locale's gettext functions
3590 with None arguments.
3591
3592- Issue #3389: Allow resolving dotted names for handlers in logging
3593 configuration files.
3594
3595- Deprecate the sunaudio module for removal in Python 3.0.
3596
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00003597- Issue #3394: zipfile.writestr sets external attributes when passed a
3598 file name rather than a ZipInfo instance, so files are extracted with
3599 mode 0600 rather than 000 under Unix.
3600
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003601- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
3602 argument in python 2.5, this broke code that subclassed Popen to include its
3603 own poll method. Fixed my moving _deadstate to an _internal_poll method.

3611-------------
3612
Nick Coghlan6e8fef02008-08-18 13:14:22 +00003613- Issue #2235: the C API function PyObject_HashNotImplemented and its
3614 interaction with the tp_hash slot (added in 2.6b2) are now documented
3615
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003616- Issue #643841: The language reference now provides more detailed
3617 coverage of the lookup process for special methods. The disclaimers
3618 regarding lack of coverage of new-style classes have also been
3619 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00003622What's New in Python 2.6 beta 2?
3623================================
3624
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003625*Release date: 17-Jul-2008*

3628-----------------
3629
Georg Brandl3e483f62008-07-16 22:57:41 +00003630- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3631 its methods now allow for items objects that can be converted to
3632 an integer using operator.index().
3633
Mark Dickinson64b7e502008-07-16 09:40:03 +00003634- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3635 produced a ValueError instead of giving the correct float.
3636
Eric Smitha5fa5a22008-07-16 00:11:49 +00003637- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3638 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3639
Mark Dickinson7103aa42008-07-15 19:08:33 +00003640- Issue #3008: the float type has a new instance method 'float.hex'
3641 and a new class method 'float.fromhex' to convert floating-point
3642 numbers to and from hexadecimal strings, respectively.
3643
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003644- Issue #2235: __hash__ is once again inherited by default. To allow
3645 collections.Hashable to remain meaningful in the presence of the
3646 default hash implementation (object.__hash__), it is now possible
3647 to explicit block inheritance of hash by setting __hash__=None at
3648 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3649 level.
3650
Nick Coghlanb028f502008-07-13 14:52:36 +00003651- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3652 the parent module cannot be found while performing an absolute import.
3653 This means that an incorrectly defined __package__ attribute will
3654 now only prevent relative imports in that module rather than causing
3655 all imports from that module to fail.
3656
Nick Coghlan14ff9942008-07-08 14:21:42 +00003657- Issue #2517: Allow unicode messages in Exceptions again by correctly
3658 bypassing the instance dictionary when looking up __unicode__ on
3659 new-style classes.
3660
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00003661- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
3662 set to a custom object whose write() method happens to install
3663 another file in sys.stdout.
3664
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00003665- Issue #3088: Corrected a race condition in classes derived from
3666 threading.local: the first member set by a thread could be saved in
3667 another thread's dictionary.
3668
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003669- Issue #3004: Minor change to slice.indices(): the start and stop
3670 arguments are now treated identically, making the behaviour easier
3671 to describe and understand. For example, slice(None, -10,
3672 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3673 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3674 10, -1).
3675
Georg Brandl278fc502008-07-19 12:46:12 +00003676- Issue #3219: Calling a function with repeated keyword arguments,
3677 f(a=2, a=23), would not cause a syntax error. This was a regression
3678 from 2.4 caused by the switch to the new compiler.

Georg Brandl278fc502008-07-19 12:46:12 +00003680- Issue #2862: Make int and float freelist management consistent with
3681 other freelists. Changes their CompactFreeList apis into
3682 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00003687- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
3688 api functions without holding the GIL, which could lead to a fatal
3689 error when they failed.
3690
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003691- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

4127 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00004128 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004129
4130 This is controlled by the configure argument ``--with-universal-archs``:
4131
4132 - ``--with-universal-archs=all``: install 4-way universal
4133
4134 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4135
4136 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4137
4138 This option should be used in combination with ``--enable-universalsdk=``.

4177 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00004178
Christian Heimese74c8f22008-04-19 02:23:57 +00004179- Added kill, terminate and send_signal(sig) to subprocess.Popen.

4182 the cmath module.
Christian Heimes6f341092008-04-18 23:13:07 +00004183

Georg Brandl3ee81df2008-05-17 18:14:43 +00004190- Issue #1631171: Re-implement the 'warnings' module in C (the
4191 original Python code has been kept as backup). This will allow for
4192 using the 'warning's machinery in such places as the parser where
4193 use of pure Python code is not possible. Both the ``showarning()``
4194 and ``formatwarning()`` gain an optional 'line' argument which is
4195 not called by default for backwards-compatibility reasons. Setting
4196 ``warnings.showwarning()`` to an implementation that lacks support
4197 for the ``line`` argument will raise a DeprecationWarning.

4221
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00004222- The getpass module has been improved on Unix. It now uses /dev/tty
4223 by default and uses stderr instead of stdout. A GetPassWarning is
4224 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00004225

Georg Brandl3ee81df2008-05-17 18:14:43 +00004239- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00004240 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00004260- Issue #2550: The approach used by client/server code for obtaining
4261 ports to listen on in network-oriented tests has been refined in an
4262 effort to facilitate running multiple instances of the entire
4263 regression test suite in parallel without issue.
4264 test_support.bind_port() has been fixed such that it will always
4265 return a unique port -- which wasn't always the case with the
4266 previous implementation, especially if socket options had been set
4267 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4268 new implementation of bind_port() will actually raise an exception
4269 if it is passed an AF_INET/SOCK_STREAM socket with either the
4270 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4271 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4272 the socket it's been passed. This currently only applies to
4273 Windows. This option prevents any other sockets from binding to the
4274 host/port we've bound to, thus removing the possibility of the
4275 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4276 when a second SOCK_STREAM socket binds and accepts to a host/port
4277 that's already been bound by another socket. The optional preferred
4278 port parameter to bind_port() has been removed. Under no
4279 circumstances should tests be hard coding ports!
4280
4281 test_support.find_unused_port() has also been introduced, which will
4282 pass a temporary socket object to bind_port() in order to obtain an
4283 unused port. The temporary socket object is then closed and
4284 deleted, and the port is returned. This method should only be used
4285 for obtaining an unused port in order to pass to an external program
4286 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4287 a parameter to a server-oriented class that doesn't give you direct
4288 access to the underlying socket used.
4289
4290 Finally, test_support.HOST has been introduced, which should be used
4291 for the host argument of any relevant socket calls (i.e. bind and
4292 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004293
4294 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004295 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004296 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4297 test_asynchat and test_socket_ssl.
4298
Georg Brandl3ee81df2008-05-17 18:14:43 +00004299 It is now possible for multiple instances of the regression test
4300 suite to run in parallel without issue.

4566Core and builtins
4567-----------------
4568
Fred Drakea8ee94b2008-03-01 02:45:07 +00004569- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004570 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00004571
Georg Brandlad61bc82008-02-23 15:11:18 +00004572- Issue #2067: file.__exit__() now calls subclasses' close() method.
4573
4574- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00004575
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004576- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00004577 issue 215555 for a discussion.
4578
Eric Smitha73fbe72008-02-23 03:09:44 +00004579- Added the future_builtins module, which contains hex() and oct().
4580 These are the PEP 3127 version of these functions, designed to be
4581 compatible with the hex() and oct() builtins from Python 3.0. They
4582 differ slightly in their output formats from the existing, unchanged
4583 Python 2.6 builtins. The expected usage of the future_builtins
4584 module is:
4585 from future_builtins import hex, oct
4586
Eric Smith7ef40bf2008-02-20 23:34:22 +00004587- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4588 exponents for exponents with absolute value < 100. Follows C99
4589 standard. This is a change on Windows, which would use 3 digits.
4590 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4591 so that any alterations it does to the resulting string will be
4592 available in stringlib/formatter.h (for float.__format__).
4593
Eric Smith5a3c1352008-02-19 13:21:56 +00004594- Implemented PEP 3101, Advanced String Formatting. This adds a new
4595 builtin format(); a format() method for str and unicode; a
4596 __format__() method to object, str, unicode, int, long, float, and
4597 datetime; the class string.Formatter; and the C API
4598 PyObject_Format().
4599
Georg Brandl3ee81df2008-05-17 18:14:43 +00004600- Fixed several potential crashes, all caused by specially crafted
4601 __del__ methods exploiting objects in temporarily inconsistent
4602 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004603
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004604- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004605 prevent a possible crash: an Abstract Base Class would try to access
4606 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004607
Georg Brandl3ee81df2008-05-17 18:14:43 +00004608- Fixed repr() and str() of complex numbers with infinity or nan as
4609 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00004610
Georg Brandl3ee81df2008-05-17 18:14:43 +00004611- Clear all free lists during a gc.collect() of the highest generation
4612 in order to allow pymalloc to free more arenas. Python may give back
4613 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004614
Georg Brandl3ee81df2008-05-17 18:14:43 +00004615- Issue #2045: Fix an infinite recursion triggered when printing a
4616 subclass of collections.defaultdict, if its default_factory is set
4617 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004618
Christian Heimesf75dbef2008-02-08 00:11:31 +00004619- Fixed a minor memory leak in dictobject.c. The content of the free
4620 list was not freed on interpreter shutdown.
4621
Georg Brandl21e99f42010-03-07 15:23:59 +00004622- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004623 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004624
Georg Brandl3ee81df2008-05-17 18:14:43 +00004625- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4626 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004627 to compact the internal free lists of pre-allocted ints and floats.
4628
Georg Brandl3ee81df2008-05-17 18:14:43 +00004629- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4630 calls. Python expected the return type int but the fork familie
4631 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004632
Georg Brandl3ee81df2008-05-17 18:14:43 +00004633- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4634 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004635
Georg Brandl3ee81df2008-05-17 18:14:43 +00004636- Issue #2025: Add tuple.count() and tuple.index() methods to comply
4637 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00004638
Georg Brandl3ee81df2008-05-17 18:14:43 +00004639- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
4640 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00004641
Georg Brandl3ee81df2008-05-17 18:14:43 +00004642- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4643 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004644
Georg Brandl3ee81df2008-05-17 18:14:43 +00004645- Patch #1473257: generator objects gain a gi_code attribute. This is
4646 the same object as the func_code attribute of the function that
4647 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004648
Georg Brandl3ee81df2008-05-17 18:14:43 +00004649- Issue #1920: "while 0" statements were completely removed by the
4650 compiler, even in the presence of an "else" clause, which is
4651 supposed to be run when the condition is false. Now the compiler
4652 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004653
Guido van Rossumeead05f2008-01-24 18:21:02 +00004654- A few crashers fixed: weakref_in_del.py (issue #1377858);
4655 loosing_dict_ref.py (issue #1303614, test67.py);
4656 borrowed_ref_[34].py (not in tracker).
4657
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004658- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004659 suppressed while an extension is loaded by calling SetErrorMode in
4660 dynload_win.c. The error is still reported properly.
4661
Georg Brandl3ee81df2008-05-17 18:14:43 +00004662- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004663 several extension methods and modules do not work without unicode
4664 support.
4665
Georg Brandl26543b12008-01-21 18:36:51 +00004666- Issue #1882: when compiling code from a string, encoding cookies in the
4667 second line of code were not always recognized correctly.
4668
Georg Brandl14404b62008-01-19 19:27:05 +00004669- Issue #1679: "0x" was taken as a valid integer literal.
4670
Georg Brandl6caad7d2008-01-26 14:19:22 +00004671- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004672 added.
4673
Christian Heimesc94e2b52008-01-14 04:13:37 +00004674- sys.float_info / PyFloat_GetInfo: The floating point information
4675 object was converted from a dict to a specialized structseq object.
4676
Georg Brandl3ee81df2008-05-17 18:14:43 +00004677- Patch #1816: Added sys.flags structseq. It exposes the status of
4678 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004679
Georg Brandl3ee81df2008-05-17 18:14:43 +00004680- Objects/structseq.c: Implemented new structseq representation. The
4681 patch makes structseqs (e.g. the return value of os.stat) more
4682 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004683
Georg Brandl3ee81df2008-05-17 18:14:43 +00004684- Patch #1700288: added a type attribute cache that caches method
4685 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004686
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004687- Bug #1776: __import__() no longer accepts filenames on any platform.

4691
Georg Brandl3ee81df2008-05-17 18:14:43 +00004692- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4693 envvar and sys.dont_write_bytecode attribute. All these can be set
4694 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004695
Georg Brandl3ee81df2008-05-17 18:14:43 +00004696- Improve some exception messages when Windows fails to load an
4697 extension module. Now we get for example '%1 is not a valid Win32
4698 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004699

4703 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004704
Christian Heimes0a8143f2007-12-18 23:22:54 +00004705- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004706 and INF. float("nan"), float("inf") and float("-inf") now work on
4707 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004708
Georg Brandl3ee81df2008-05-17 18:14:43 +00004709- Compiler now generates simpler and faster code for dictionary
4710 literals. The oparg for BUILD_MAP now indicates an estimated
4711 dictionary size. There is a new opcode, STORE_MAP, for adding
4712 entries to the dictionary.

4742 file can now be directly executed by passing their name to the
4743 interpreter. The directory/zipfile is automatically inserted as the
4744 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004745
Georg Brandl3ee81df2008-05-17 18:14:43 +00004746- Issue #1265: Fix a problem with sys.settrace, if the tracing
4747 function uses a generator expression when at the same time the
4748 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004749
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004750- sets and frozensets now have an isdisjoint() method.
4751

4755
Georg Brandl21e99f42010-03-07 15:23:59 +00004756- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004757 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4758 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004759
Georg Brandl3ee81df2008-05-17 18:14:43 +00004760- Issue #1686386: Tuple's tp_repr did not take into account the
4761 possibility of having a self-referential tuple, which is possible
4762 from C code. Nor did object's tp_str consider that a type's tp_str
4763 could do something that could lead to an inifinite recursion.
4764 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4765 issues.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004767- Issue #1164: It was possible to trigger deadlock when using the
4768 'print' statement to write to a file since the GIL was not released
4769 as needed. Now PyObject_Print() does the right thing along with
4770 various tp_print implementations of the built-in types and those in
4771 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004772
Georg Brandl3ee81df2008-05-17 18:14:43 +00004773- Issue #1147: Exceptions were directly allowing string exceptions in
4774 their throw() method even though string exceptions no longer
4775 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004776
Georg Brandl3ee81df2008-05-17 18:14:43 +00004777- Issue #1096: Prevent a segfault from getting the repr of a very
4778 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004779
Brett Cannon1e534b52007-09-07 04:18:30 +00004780- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004781 PyObject_Call() never calling back out to Python code to trigger
4782 recursion depth updates/checks. Required the creation of a static
4783 RuntimeError instance in case normalizing an exception put the
4784 recursion check value past its limit. Fixes crashers
4785 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004786
Georg Brandl3ee81df2008-05-17 18:14:43 +00004787- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00004800- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004801 __*__ attributes. (Some already existed, e.g., __doc__ and
4802 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004803
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004804- Add -3 option to the interpreter to warn about features that are
4805 deprecated and will be changed/removed in Python 3.0.
4806
Georg Brandl2134e752007-05-21 20:34:16 +00004807- Patch #1686487: you can now pass any mapping after '**' in function
4808 calls.
4809
Collin Winter62903052007-05-18 23:11:24 +00004810- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004811 "except E as target:". This is to provide forwards compatibility
4812 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004813
Brett Cannon229cee22007-05-05 01:34:02 +00004814- Deprecate BaseException.message as per PEP 352.
4815
Georg Brandl3ee81df2008-05-17 18:14:43 +00004816- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004817 inherited from a built-in base.

Vinay Sajip8549ce32007-05-06 17:53:37 +00004819- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004820 setting a plain string, ie don't expand to single letter identifiers.
4821
Raymond Hettinger13936692007-04-11 18:40:58 +00004822- Request #1191699: Slices can now be pickled.
4823
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004824- Request #1193128: str.translate() now allows a None argument for
4825 translations that only remove characters without re-mapping the
4826 remaining characters.
4827
Georg Brandl5cb76c12007-03-21 09:00:39 +00004828- Patch #1682205: a TypeError while unpacking an iterable is no longer
4829 masked by a generic one with the message "unpack non-sequence".
4830
Neal Norwitzaa754b72007-03-21 06:39:48 +00004831- Remove unused file Python/fmod.c.
4832
Guido van Rossum143b5642007-03-23 04:58:42 +00004833- Bug #1683368: The object.__init__() and object.__new__() methods are
4834 now stricter in rejecting excess arguments. The only time when
4835 either allows excess arguments is when it is not overridden and the
4836 other one is. For backwards compatibility, when both are
4837 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004838 warning later). Also, type.__init__() insists on the same signature
4839 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004840
Georg Brandl3ee81df2008-05-17 18:14:43 +00004841- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4842 object to complex using its __complex__() method before falling back
4843 to the __float__() method. Therefore, the functions in the cmath
4844 module now can operate on objects that define a __complex__()
4845 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004846
Georg Brandl3ee81df2008-05-17 18:14:43 +00004847- Patch #1623563: allow __class__ assignment for classes with
4848 __slots__. The old and the new class are still required to have the
4849 same slot names.

4855 ``object.__reduce_ex__()`` is called with an object that is faking
4856 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00004857
Georg Brandl3ee81df2008-05-17 18:14:43 +00004858- Patch #1680015: Don't modify __slots__ tuple if it contains an

4862
Georg Brandl7b9c5552007-03-12 14:30:05 +00004863- Bug #1678647: write a newline after printing an exception in any
4864 case, even when converting the value to a string failed.
4865
Georg Brandl871f1bc2007-03-12 13:17:36 +00004866- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004867 its argument, if it exists. If not, it will work like before. This
4868 allows customizing the output of dir() in the presence of a
4869 __getattr__().

4878 parthensized forms. This means complex(repr(x)) now works instead of
4879 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004880
Georg Brandlaa2321b2007-03-07 00:40:28 +00004881- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004882 makes the filenames the warning module prints much more sensible
4883 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004884
Georg Brandl49aafc92007-03-07 00:34:46 +00004885- Variant of patch #697613: don't exit the interpreter on a SystemExit
4886 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00004887 variable is given, but break into the interactive interpreter just
4888 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00004896- Patch #1674228: when assigning a slice (old-style), check for the
4897 sq_ass_slice instead of the sq_slice slot.
4898
Georg Brandl3ee81df2008-05-17 18:14:43 +00004899- When printing an unraisable error, don't print exceptions. before
4900 the name. This duplicates the behavior whening normally printing
4901 exceptions.

5510 Python would crash instead of raising an error.

5529 -- the failure just occurred later, with a more cumbersome
5530 exception.

5743 partial fix for Bug #1574584.
5744
Georg Brandl3ee81df2008-05-17 18:14:43 +00005745- Fix turtle so that time.sleep is imported for the entire library.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005811- Issue #829951: In the smtplib module, SMTP.starttls() now complies
5812 with RFC 3207 and forgets any knowledge obtained from the server not
5813 obtained from the TLS negotiation itself. Patch contributed by Bill
5814 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00005815
Georg Brandl3ee81df2008-05-17 18:14:43 +00005816- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005817 that the SMTP.starttls() caller no longer needs to call ehlo()
5818 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00005819 does not claim to support starttls. Adds the
5820 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
5821 Fenner.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005863- Patch #976880: ``mmap`` objects now have an ``rfind`` method that
Andrew M. Kuchling5c60bfc2008-01-19 18:18:41 +00005864 works as expected. ``mmap.find`` also takes an optional ``end``

5901 complex, tuple, list, dict, set, and frozenset. Formerly, it would
5902 silently miscode subclasses of those types. Now, it raises a
5903 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00005904

Georg Brandl3ee81df2008-05-17 18:14:43 +00005919 time so that opening a database previously created with the DB_DUP
5920 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5921 opens. Specifically: dictionary assignment to a DB object will
5922 replace all values for a given key when the database allows
5923 duplicate values. DB users should use DB.put(k, v) when they want
5924 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005925

5931 characters with ASCII value less than 32. Also, it correctly quotes
5932 dots only if they occur on a single line, as opposed to the previous
5933 behavior of quoting dots if they are the second character of any
5934 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00005935

6257-----
6258
Georg Brandl3ee81df2008-05-17 18:14:43 +00006259- Unified naming convention for free lists and their limits. All free
6260 lists in Object/ are named ``free_list``, the counter ``numfree``
6261 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
6262 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00006263
Georg Brandl3ee81df2008-05-17 18:14:43 +00006264- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
6265 to ``PyTuple_SetItem``, it can be used to populate a brand new
6266 frozenset; but it does not steal a reference to the added item.

6271 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
6272 PyLong_FromSsize_t public functions.

6274- Patch #1720595: add T_BOOL to the range of structmember types.
6275
6276- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
6277 ``PyFloat_GetInfo()`` to the float API.
6278
Georg Brandl3ee81df2008-05-17 18:14:43 +00006279- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
6280 of w# format code incorrectly truncated the length to an int, even
6281 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
6282 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006283
Georg Brandl3ee81df2008-05-17 18:14:43 +00006284- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
6285 Py_TYPE and Py_REFCNT.

6302- Fix some leftovers from the conversion from int to Py_ssize_t
6303 (relevant to strings and sequences of more than 2**31 items).
6304
6305- Make _PyGILState_NoteThreadState() static, it was not used anywhere
6306 outside of pystate.c and should not be necessary.
6307
Georg Brandl3ee81df2008-05-17 18:14:43 +00006308- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
6309 absolute imports. In earlier versions they might have used relative
6310 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00006311
Georg Brandl3ee81df2008-05-17 18:14:43 +00006312- Added case insensitive comparison methods ``PyOS_stricmp(char*,
6313 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00006314
Georg Brandl3ee81df2008-05-17 18:14:43 +00006315- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00006322- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
6323 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
6324 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
6325 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00006326

Georg Brandl3ee81df2008-05-17 18:14:43 +00006340- Removed the macfs module. It had been deprecated since Python 2.5.
6341 This lead to the deprecation of macostools.touched() as it relied
6342 solely on macfs and was a no-op under OS X.
