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

275 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

R. David Murray1a14d3d2010-04-12 16:35:19 +0000572- Issue #7585: difflib context and unified diffs now place a tab between
Georg Brandlfee0f442010-05-22 21:26:21 +0000573 filename and date, conforming to the 'standards' they were originally designed
574 to follow. This improves compatibility with patch tools.

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +0000620 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
621 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
622 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

642Core and Builtins
643-----------------
644
Philip Jenveyaebbaeb2010-04-06 23:24:45 +0000645- Issue #7301: Add environment variable $PYTHONWARNINGS.
646
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +0000647- Issue #8329: Don't return the same lists from select.select when no fds are
648 changed.
649
Georg Brandlfee0f442010-05-22 21:26:21 +0000650- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +0000651 on 64-bit machines. The shift count for either left or right shift is
652 permitted to be up to sys.maxsize.
653
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +0000654- Ensure that tokenization of identifiers is not affected by locale.
655
Georg Brandlfee0f442010-05-22 21:26:21 +0000656- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.

Benjamin Peterson1c7c11e2010-04-03 01:28:57 +0000658- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
659
Georg Brandlfee0f442010-05-22 21:26:21 +0000660- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
661 with a non-empty format string. This is an effort to future-proof user
662 code. If a derived class does not currently implement __format__ but later
663 adds its own __format__, it would most likely break user code that had
664 supplied a format string. This will be changed to a DeprecationWaring in
665 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +0000666
Antoine Pitroua57df2c2010-03-31 21:32:15 +0000667- Issue #8268: Old-style classes (not just instances) now support weak
668 references.

691
Antoine Pitrouf9de5342010-04-05 21:35:07 +0000692- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +0000693 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and
694 `ssl.OPENSSL_VERSION_NUMBER`.

697
Georg Brandlfee0f442010-05-22 21:26:21 +0000698- Issue #8257: The Decimal construct now accepts a float instance directly,
699 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +0000700
701 >>> Decimal(1.1)
702 Decimal('1.100000000000000088817841970012523233890533447265625')
703
Raymond Hettinger34c35b22010-04-03 10:22:00 +0000704- collections.Counter() now supports a subtract() method.
705
Georg Brandlfee0f442010-05-22 21:26:21 +0000706- The functools module now has a total_ordering() class decorator to simplify
707 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +0000708
Georg Brandlfee0f442010-05-22 21:26:21 +0000709- The functools module also adds cmp_to_key() as a tool to transition old-style
710 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +0000711
Georg Brandlfee0f442010-05-22 21:26:21 +0000712- Issue #8294: The Fraction constructor now accepts Decimal and float instances
713 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +0000714
Georg Brandlfee0f442010-05-22 21:26:21 +0000715- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
716 InvalidOperation instead of returning False. (Comparisons involving a quiet
717 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
718 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +0000719
Georg Brandlfee0f442010-05-22 21:26:21 +0000720- Issue #2531: Comparison operations between floats and Decimal instances now
721 return a result based on the numeric values of the operands; previously they
722 returned an arbitrary result based on the relative ordering of id(float) and
723 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +0000724
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000725- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +0000726 argument `-` which tells it to read files to compile from stdin. Each line is
727 read on demand and the named file is compiled immediately. (Original patch by
728 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000729
Georg Brandlfee0f442010-05-22 21:26:21 +0000730- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +0000733- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
734 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +0000735 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +0000736
Georg Brandlfee0f442010-05-22 21:26:21 +0000737- Comparisons using one of <, <=, >, >= between a complex instance and a
738 Fractions instance now raise TypeError instead of returning True/False. This
739 makes Fraction <=> complex comparisons consistent with int <=> complex, float
740 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +0000741
Michael Foorde6410c52010-03-29 20:04:23 +0000742- Addition of ``WeakSet`` to the ``weakref`` module.

750
Antoine Pitrou513d9ae2010-03-22 19:59:46 +0000751- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +0000752 didn't support chflags() (for example ZFS under FreeBSD). The error is now
753 silenced.
Antoine Pitrou513d9ae2010-03-22 19:59:46 +0000754
Florent Xicluna9e7a4c92010-03-22 16:07:38 +0000755- Issue #7703: ctypes supports both buffer() and memoryview(). The former is

Vinay Sajipecfa08f2010-03-12 09:16:10 +0000795- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlfee0f442010-05-22 21:26:21 +0000796 for ``TimedRotatingFileHandler`` by using the modification time of an existing
797 log file to compute the next rollover time. If the log file does not exist,
798 the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +0000799
Georg Brandlba83f822010-03-14 09:50:54 +0000800- Issue #6472: The ``xml.etree`` package is updated to ElementTree 1.3. The

809 a base64 transfer-encoded payload *after* decoding it; it no longer does.
810 This is a behavior change, so email's minor version number is now bumped, to

Mark Dickinson4846a8e2010-04-03 14:05:10 +0000839- Issue #8300: When passing a non-integer argument to struct.pack with any
840 integer format code, struct.pack first attempts to convert the non-integer
841 using its __index__ method. If that method is non-existent or raises
842 TypeError it goes on to try the __int__ method, as described below.
843
Georg Brandlba83f822010-03-14 09:50:54 +0000844- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
845 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
846 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +0000847 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
848 inconsistent: __int__ was used for some integer codes but not for others, and
849 the set of integer codes for which it was used differed between native packing
850 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00001057- Issue #7712: test_support gained a new ``temp_cwd`` context manager which is
1058 now also used by regrtest to run all the tests in a temporary directory. The
1059 original CWD is saved in ``test.test_support.SAVEDCWD``. Thanks to Florent
1060 Xicluna who helped with the patch.

1077 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +00001078 library would return a bogus result; on Solaris, it was possible to crash the
1079 interpreter. Patch by Stefan Krah.

Georg Brandlba83f822010-03-14 09:50:54 +00001092- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
1093 and add the additional members returned in an OSVERSIONINFOEX structure. The
1094 new members are service_pack_major, service_pack_minor, suite_mask, and

Georg Brandlba83f822010-03-14 09:50:54 +00001097- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
1098 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
1099 returning NULL. The macro now returns a statically allocated empty string
1100 instead.

1110 strings,
1111 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
1112 numeric strings corresponding to subnormal values,
1113 (3) a memory leak for some values large enough to cause overflow, and
1114 (4) a number of flaws that could lead to incorrectly rounded results.

1133
Georg Brandlba83f822010-03-14 09:50:54 +00001134- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">") in

Antoine Pitroud840e512010-02-04 20:20:18 +00001145- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00001146 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00001147 Also, raise ValueError rather than TypeError when an unknown TIPC address
1148 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001152- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00001153 file position when calling `truncate()`. It would previously change the file
1154 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001155 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
1156
Georg Brandlba83f822010-03-14 09:50:54 +00001157- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
1158 class used to represent files stored inside an archive. The new
1159 implementation is significantly faster and can be wrapped in a
1160 ``io.BufferedReader`` object for more speedups. It also solves an issue
1161 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
1162 Patch by Nir Aides.
Antoine Pitrou94c33eb2010-01-27 20:59:50 +00001163
Benjamin Peterson2deb5c72010-01-27 02:16:42 +00001164- Issue #7792: Registering non-classes to ABCs raised an obscure error.

Benjamin Petersona43f34c2010-01-25 03:31:13 +00001171
Georg Brandlba83f822010-03-14 09:50:54 +00001172- Issue #7748: Since unicode values are supported for some metadata options in
1173 Distutils, the DistributionMetadata get_* methods will now return an utf-8
1174 encoded string for them. This ensures that the upload and register commands
1175 send the correct values to PyPI without any error.

1251
Georg Brandlba83f822010-03-14 09:50:54 +00001252- The ``__complex__()`` method is now looked up on the class of instances to
1253 make it consistent with other special methods.

1257
Mark Dickinson1b34d252010-01-01 17:27:30 +00001258- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001259 DeprecationWarning when passed a float argument where an integer was expected.
1260 These functions and methods now raise TypeError instead. The majority of the
1261 effects of this change are in the extension modules, but some core functions
1262 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1263 and many unicode/str methods.

1279 internal representation of a long.

1287
Georg Brandlba83f822010-03-14 09:50:54 +00001288 These executables now work properly with the arch(1) command: ``arch -ppc
1289 python`` will start a universal binary version of python in PPC mode (unlike

1430 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001431
Georg Brandlba83f822010-03-14 09:50:54 +00001432- Remove switch from "%f" formatting to "%g" formatting for floats larger than
1433 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00001434
Georg Brandlba83f822010-03-14 09:50:54 +00001435- Remove restrictions on precision when formatting floats. E.g., "%.120g" %

1437 significant digits instead.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00001445
Georg Brandlba83f822010-03-14 09:50:54 +00001446- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1447 decimal string that's guaranteed to round back to x under correct rounding
1448 (with round-half-to-even rounding mode). Previously it gave a string based on
1449 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1450 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1451 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001452
Georg Brandlba83f822010-03-14 09:50:54 +00001453- Issue #7117: On almost all platforms: float-to-string and string-to-float
1454 conversions within Python are now correctly rounded. Places these conversions
1455 occur include: str for floats and complex numbers; the float and complex
1456 constructors; old-style and new-style numeric formatting; serialization and
1457 deserialization of floats and complex numbers using marshal, pickle and json;
1458 parsing of float and imaginary literals in Python code; Decimal-to-float
1459 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001460
Georg Brandlba83f822010-03-14 09:50:54 +00001461 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1462 providing correctly-rounded strtod and dtoa C functions. This code is
1463 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1464 the C compiler. There may be a small number of platforms on which correct
1465 operation of this code cannot be guaranteed, so the code is not used: notably,
1466 this applies to platforms where the C double format is not IEEE 754 binary64,
1467 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1468 and Python's configure script is unable to determine how to change the FPU
1469 precision. On these platforms conversions use the platform strtod and dtoa,
1470 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001471
Georg Brandlba83f822010-03-14 09:50:54 +00001472- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1473 uses the correctly-rounded string <-> float conversions described above (when
1474 available), and so produces correctly rounded results that will display nicely
1475 under the float repr. There are two related small changes: (1) round now
1476 accepts any class with an ``__index__()`` method for its second argument (but
1477 no longer accepts floats for the second argument), and (2) an excessively
1478 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1479 raises an exception.

1628 but with at least one decimal point and with a default precision
1629 of 12. Previously, the behavior the same but with a default precision of 6.
1630 This more closely matches ``str()``, and reduces surprises when adding

1765 collecting the oldest generation) so that allocating lots of objects without

Georg Brandlba83f822010-03-14 09:50:54 +00001772- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
1773 existing .py counterpart, override the co_filename attributes of all code
1774 objects if the original filename is obsolete (which can happen if the file has
1775 been renamed, moved, or if it is accessed through different paths). Patch by

Georg Brandlba83f822010-03-14 09:50:54 +00001815- Issue #4445: Replace ``sizeof(PyStringObject)`` with
1816 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
1817 instances. On a typical machine this saves 3 bytes of memory (on average) per

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00001820- Issue #3996: On Windows, the PyOS_CheckStack function would cause the

1822 instead of throwing a MemoryError.
1823
Georg Brandlba83f822010-03-14 09:50:54 +00001824- Issue #3689: The list reversed iterator now supports __length_hint__ instead

1829
Georg Brandlba83f822010-03-14 09:50:54 +00001830- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
1831 file objects with closefd=False. The file descriptor is still kept open but
1832 the file object behaves like a closed file. The ``FileIO`` object also got a
1833 new readonly attribute ``closefd``.

Benjamin Peterson46cc6d12008-11-19 21:49:09 +00001835- Issue #4348: Some bytearray methods returned that didn't cause any change to

1852
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00001853- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00001854 because it is a reserved word in 3.x.

Georg Brandlba83f822010-03-14 09:50:54 +00001856- On windows, ``os.chdir()`` given unicode was not working if
1857 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
1858 this code path is really executed because I cannot move to such directory on
1859 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00001861- Issue #4069: When ``set.remove(element)`` is used with a set element, the
1862 element is temporarily replaced with an equivalent frozenset. But the
1863 eventual KeyError would always report the empty ``frozenset()`` as the missing
1864 key. Now it correctly refers to the initial element.

1883
Walter Dörwalded960ac2009-05-03 22:36:33 +00001884- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
1885 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1886 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1887 of using the replace error handler in PyUnicode_DecodeUTF8().
1888
Walter Dörwald726ba8e2009-05-06 14:32:35 +00001889- Issue #3739: The unicode-internal encoder now reports the number of characters
1890 consumed like any other encoder (instead of the number of bytes).
1891
Georg Brandlba83f822010-03-14 09:50:54 +00001892- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
1893 allocator will be automatically disabled when running under Valgrind. This
1894 gives improved memory leak detection when running under Valgrind, while taking
1895 advantage of pymalloc at other times.

3126 __all__ attribute, rather than using a hardcoded and incomplete list.
3127
R. David Murray14dcd432009-10-14 13:58:07 +00003128- Issue #7058: Added save/restore for things like sys.argv and cwd to
3129 runtest_inner in regrtest, with warnings if the called test modifies them,
3130 and a new section in the summary report at the end.

Guilherme Polo7f146ab2009-06-21 17:22:50 +00003137- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
3138 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00003139 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
3140 the tests if DISPLAY is defined but can't be used.

Antoine Pitrou4698d992009-05-31 14:20:14 +00003142- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
3143 regression tests in parallel, shortening the total runtime.
3144
Georg Brandlba83f822010-03-14 09:50:54 +00003145- Issue #5354: New test support function import_fresh_module() makes it easy to
3146 import both normal and optimised versions of modules. test_heapq and
3147 test_warnings have been adjusted to use it, tests for other modules with both
3148 C and Python implementations in the stdlib can be adjusted to use it over
3149 time.

Georg Brandlba83f822010-03-14 09:50:54 +00003157- regrtest no longer treats ImportError as equivalent to SkipTest. Imports that
3158 should cause a test to be skipped are now done using import_module from test
3159 support, which does the conversion.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00003260- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
3261
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003262- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3263 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3264 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3265 ``printf`` function, whereas PyString_FromFormat has an independent
3266 implementation and uses "%zd" on all platforms for size_t values.
3267 This makes a difference on win64, where ``printf`` needs "%Id" to display
3268 64bit values.
3269
Benjamin Peterson97179b02008-09-09 20:55:01 +00003270- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

3274 object; previously an int would be returned for small values. the __long__
3275 method is allowed to return either an int or a long, but the behaviour of
3276 float objects should not change to respect backward compatibility.
3277
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00003278- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +00003284 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003285 was correctly parsed but parsing of subsequent arguments failed.
3286
Vinay Sajip35e3b032008-09-01 14:33:59 +00003287- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003288 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3289 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3290 when given a tuple of classes as second argument, were looking up
3291 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3292 type object.
3293
Neal Norwitz18aa3882008-08-24 05:04:52 +00003294- Fix crashes on memory allocation failure found with failmalloc.

Martin v. Löwisab0b29b2008-09-13 08:11:57 +00003420- Issue #3833: Use a different upgrade code for Win64 installers.
3421
Martin v. Löwis3f5fda82008-09-08 13:50:10 +00003422- Issue #2271: Set SecureCustomProperties so that installation will properly
3423 use the TARGETDIR even for unprivileged users.
3424
Martin v. Löwis67543a92008-09-08 12:02:45 +00003425- Allow passing the MSI file name to merge.py.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003431What's New in Python 2.6 beta 3?
3432================================
3433
Barry Warsaw07a4a382008-08-21 01:15:08 +00003434*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003435
3436Core and Builtins
3437-----------------
3438
Guido van Rossumf8402962008-08-20 15:01:50 +00003439- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3440 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3441 extensions do not automatically benefit from the class attribute
3442 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3443 to their tp_flags field if they care. This is a backwards
3444 compatibility feature; in 3.0, all types will use the cache by
3445 default.
3446
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003447- Keyword arguments can now follow starred arguments. (``f(a, *args,
3448 keyword=23)`` is now valid syntax.)
3449
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003450- ctypes function pointers that are COM methods have a boolean True
3451 value again.
3452
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003453- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3454 by denying s# to parse objects that have a releasebuffer procedure,
3455 and introducing s*.
3456
Georg Brandl1e13ea92008-08-11 09:07:59 +00003457- Issue #3537: Fix an assertion failure when an empty but presized dict
3458 object was stored in the freelist.
3459
Mark Dickinsonb6467572008-08-04 21:30:09 +00003460- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3461 ValueError consistently across platforms.
3462
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003463- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3464 (64bit Unix, for example), unichr() would truncate its argument and return
3465 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3466
Neal Norwitze7d8be82008-07-31 17:17:14 +00003467- Apply security patches from Apple.
3468
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003469- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3470 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3471
Antoine Pitrou92f82162008-07-25 22:22:08 +00003472- Issue #1819: function calls with several named parameters are now on
3473 average 35% faster (as measured by pybench).
3474
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003475- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3476 the python debugger steps into a class statement: the free variables (local
3477 variables defined in an outer scope) would be deleted from the outer scope.
3478
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003479- Issue #2620: Overflow checking when allocating or reallocating memory
3480 was not always being done properly in some python types and extension
3481 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3482 all been updated to perform better checks and places in the code that
3483 would previously leak memory on the error path when such an allocation
3484 failed have been fixed.
3485
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003486Library
3487-------
3488
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003489- Issue #3612: Added some missing basic types in ctypes.wintypes.
3490
Benjamin Petersone977ad42008-08-20 01:42:01 +00003491- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3492 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3493
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003494- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3495 version reported by these tools does not necessarily follow the python
3496 version numbering scheme, so the module is less strict when parsing it.
3497
Nick Coghlanf70385a2008-08-18 12:42:46 +00003498- Issue #2235: Added Py3k warnings for types which will become unhashable
3499 under the stricter __hash__ inheritance rules in 3.0. Several types
3500 which did not meet the rules for hash invariants and were already
3501 unhashable in 3.0 have now been explicitly flagged as unhashable in
3502 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3503 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3504
Brett Cannon88f801d2008-08-18 00:46:22 +00003505- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3506 imported into the module but exposed as part of the module's API.
3507
Brett Cannon7b96f072008-08-18 00:41:11 +00003508- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3509
Brett Cannon46225e72008-08-18 00:36:52 +00003510- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
3511
Brett Cannon25c9d6a2008-08-17 22:10:11 +00003512- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
3513
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003514- Issue #3575: Incremental decoder's decode function now takes bytearray
3515 by using 's*' instead of 't#'.
3516
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003517- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003518 fails unicode conversion on 2nd parameter. (windows only)
3519
Facundo Batista94f243a2008-08-17 03:38:39 +00003520- Issue 2464. urllib2 now supports a malformation in the URL received
3521 in a redirect.
3522
Brett Cannonabe423e2008-08-16 21:47:07 +00003523- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003524 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003525
Facundo Batistaeb90b782008-08-16 14:44:07 +00003526- Issue #2776: fixed small issue when handling an URL with double slash
3527 after a 302 response in the case of not going through a proxy.
3528
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003529- Issue #2676: in the email package, content-type parsing was hanging on
3530 pathological input because of quadratic or exponential behaviour of a
3531 regular expression.
3532
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003533- Issue #3476: binary buffered reading through the new "io" library is now
3534 thread-safe.
3535
Brett Cannonbf3157b2008-08-14 05:00:03 +00003536- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3537 since mimetools itself is deprecated. Because modules are cached, all
3538 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3539
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003540- Issue #3134: shutil referenced undefined WindowsError symbol.
3541
Robert Schuppenies14646332008-08-10 11:01:53 +00003542- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3543 menu entries were not deleted.
3544
Brett Cannon83e81842008-08-09 23:30:55 +00003545- Copied the implementation of reduce() to _functools.reduce() to have a
3546 version that did not raise a DeprecationWarning under -3.
3547
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003548- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3549 a MemoryError rather than silently stop the iteration.
3550
Guido van Rossum59ce9012008-08-09 14:55:34 +00003551- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3552 to _sre.compile() will now be rejected. This should not affect anybody
3553 since the re.compile() function never generates invalid re-bytecode.
3554
Skip Montanaroa032bf42008-08-08 22:52:51 +00003555- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3556 upon first access it can be automatically initialized from the csv file if
3557 it wasn't initialized during instantiation.
3558
Brett Cannon3aa2a492008-08-06 22:28:09 +00003559- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3560 the reload() built-in has been removed.
3561
Brett Cannon7e30b672008-08-04 21:52:25 +00003562- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003563 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00003564 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
3565 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
3566 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
3567 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
3568 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00003569
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00003570- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
3571 raised an AttributeError.
3572
Benjamin Peterson01a24322008-07-28 23:35:27 +00003573- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00003574 asking for a specific length. This problem only affected files opened
3575 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003576
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00003577- Issue #3449: Update decimal module to use most recent specification
3578 (v. 1.68) and tests (v. 2.58) from IBM.
3579
Skip Montanarof9ac43f2008-07-27 00:50:41 +00003580- Issue 3437: Bug fix in robotparser parsing of Allow: lines.
3581
Raymond Hettinger8c664e82008-07-25 18:43:33 +00003582- Issue 1592: Improve error reporting when operations are attempted
3583 on a closed shelf.

3586
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003587- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
3588
3589- Issue #3303: Fix a crash in locale.strcoll() when calling it with
3590 invalid arguments.
3591
3592- Issue #3302: Fix several crashes when calling locale's gettext functions
3593 with None arguments.
3594
3595- Issue #3389: Allow resolving dotted names for handlers in logging
3596 configuration files.
3597
3598- Deprecate the sunaudio module for removal in Python 3.0.
3599
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00003600- Issue #3394: zipfile.writestr sets external attributes when passed a
3601 file name rather than a ZipInfo instance, so files are extracted with
3602 mode 0600 rather than 000 under Unix.
3603
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003604- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
3605 argument in python 2.5, this broke code that subclassed Popen to include its
3606 own poll method. Fixed my moving _deadstate to an _internal_poll method.

3614-------------
3615
Nick Coghlan6e8fef02008-08-18 13:14:22 +00003616- Issue #2235: the C API function PyObject_HashNotImplemented and its
3617 interaction with the tp_hash slot (added in 2.6b2) are now documented
3618
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003619- Issue #643841: The language reference now provides more detailed
3620 coverage of the lookup process for special methods. The disclaimers
3621 regarding lack of coverage of new-style classes have also been
3622 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00003625What's New in Python 2.6 beta 2?
3626================================
3627
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003628*Release date: 17-Jul-2008*

3631-----------------
3632
Georg Brandl3e483f62008-07-16 22:57:41 +00003633- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3634 its methods now allow for items objects that can be converted to
3635 an integer using operator.index().
3636
Mark Dickinson64b7e502008-07-16 09:40:03 +00003637- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3638 produced a ValueError instead of giving the correct float.
3639
Eric Smitha5fa5a22008-07-16 00:11:49 +00003640- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3641 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3642
Mark Dickinson7103aa42008-07-15 19:08:33 +00003643- Issue #3008: the float type has a new instance method 'float.hex'
3644 and a new class method 'float.fromhex' to convert floating-point
3645 numbers to and from hexadecimal strings, respectively.
3646
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003647- Issue #2235: __hash__ is once again inherited by default. To allow
3648 collections.Hashable to remain meaningful in the presence of the
3649 default hash implementation (object.__hash__), it is now possible
3650 to explicit block inheritance of hash by setting __hash__=None at
3651 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3652 level.
3653
Nick Coghlanb028f502008-07-13 14:52:36 +00003654- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3655 the parent module cannot be found while performing an absolute import.
3656 This means that an incorrectly defined __package__ attribute will
3657 now only prevent relative imports in that module rather than causing
3658 all imports from that module to fail.
3659
Nick Coghlan14ff9942008-07-08 14:21:42 +00003660- Issue #2517: Allow unicode messages in Exceptions again by correctly
3661 bypassing the instance dictionary when looking up __unicode__ on
3662 new-style classes.
3663
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00003664- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
3665 set to a custom object whose write() method happens to install
3666 another file in sys.stdout.
3667
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00003668- Issue #3088: Corrected a race condition in classes derived from
3669 threading.local: the first member set by a thread could be saved in
3670 another thread's dictionary.
3671
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003672- Issue #3004: Minor change to slice.indices(): the start and stop
3673 arguments are now treated identically, making the behaviour easier
3674 to describe and understand. For example, slice(None, -10,
3675 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3676 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3677 10, -1).
3678
Georg Brandl278fc502008-07-19 12:46:12 +00003679- Issue #3219: Calling a function with repeated keyword arguments,
3680 f(a=2, a=23), would not cause a syntax error. This was a regression
3681 from 2.4 caused by the switch to the new compiler.

3691 api functions without holding the GIL, which could lead to a fatal
3692 error when they failed.
3693
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003694- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

4128
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004129- On MacOS X it is now possible to install the framework in 64-bit
4130 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00004131 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004132
4133 This is controlled by the configure argument ``--with-universal-archs``:
4134
4135 - ``--with-universal-archs=all``: install 4-way universal
4136
4137 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4138
4139 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4140
4141 This option should be used in combination with ``--enable-universalsdk=``.

4180 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00004181
Christian Heimese74c8f22008-04-19 02:23:57 +00004182- Added kill, terminate and send_signal(sig) to subprocess.Popen.
4183

4185 the cmath module.
Christian Heimes6f341092008-04-18 23:13:07 +00004186

Georg Brandl3ee81df2008-05-17 18:14:43 +00004193- Issue #1631171: Re-implement the 'warnings' module in C (the
4194 original Python code has been kept as backup). This will allow for
4195 using the 'warning's machinery in such places as the parser where
4196 use of pure Python code is not possible. Both the ``showarning()``
4197 and ``formatwarning()`` gain an optional 'line' argument which is
4198 not called by default for backwards-compatibility reasons. Setting
4199 ``warnings.showwarning()`` to an implementation that lacks support
4200 for the ``line`` argument will raise a DeprecationWarning.

4224
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00004225- The getpass module has been improved on Unix. It now uses /dev/tty
4226 by default and uses stderr instead of stdout. A GetPassWarning is
4227 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00004228

Georg Brandl3ee81df2008-05-17 18:14:43 +00004242- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00004243 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00004263- Issue #2550: The approach used by client/server code for obtaining
4264 ports to listen on in network-oriented tests has been refined in an
4265 effort to facilitate running multiple instances of the entire
4266 regression test suite in parallel without issue.
4267 test_support.bind_port() has been fixed such that it will always
4268 return a unique port -- which wasn't always the case with the
4269 previous implementation, especially if socket options had been set
4270 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4271 new implementation of bind_port() will actually raise an exception
4272 if it is passed an AF_INET/SOCK_STREAM socket with either the
4273 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4274 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4275 the socket it's been passed. This currently only applies to
4276 Windows. This option prevents any other sockets from binding to the
4277 host/port we've bound to, thus removing the possibility of the
4278 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4279 when a second SOCK_STREAM socket binds and accepts to a host/port
4280 that's already been bound by another socket. The optional preferred
4281 port parameter to bind_port() has been removed. Under no
4282 circumstances should tests be hard coding ports!
4283
4284 test_support.find_unused_port() has also been introduced, which will
4285 pass a temporary socket object to bind_port() in order to obtain an
4286 unused port. The temporary socket object is then closed and
4287 deleted, and the port is returned. This method should only be used
4288 for obtaining an unused port in order to pass to an external program
4289 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4290 a parameter to a server-oriented class that doesn't give you direct
4291 access to the underlying socket used.
4292
4293 Finally, test_support.HOST has been introduced, which should be used
4294 for the host argument of any relevant socket calls (i.e. bind and
4295 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004296
4297 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004298 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004299 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4300 test_asynchat and test_socket_ssl.
4301
Georg Brandl3ee81df2008-05-17 18:14:43 +00004302 It is now possible for multiple instances of the regression test
4303 suite to run in parallel without issue.

4569Core and builtins
4570-----------------
4571
Fred Drakea8ee94b2008-03-01 02:45:07 +00004572- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004573 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00004574
Georg Brandlad61bc82008-02-23 15:11:18 +00004575- Issue #2067: file.__exit__() now calls subclasses' close() method.
4576
4577- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00004578
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004579- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00004580 issue 215555 for a discussion.
4581
Eric Smitha73fbe72008-02-23 03:09:44 +00004582- Added the future_builtins module, which contains hex() and oct().
4583 These are the PEP 3127 version of these functions, designed to be
4584 compatible with the hex() and oct() builtins from Python 3.0. They
4585 differ slightly in their output formats from the existing, unchanged
4586 Python 2.6 builtins. The expected usage of the future_builtins
4587 module is:
4588 from future_builtins import hex, oct
4589
Eric Smith7ef40bf2008-02-20 23:34:22 +00004590- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4591 exponents for exponents with absolute value < 100. Follows C99
4592 standard. This is a change on Windows, which would use 3 digits.
4593 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4594 so that any alterations it does to the resulting string will be
4595 available in stringlib/formatter.h (for float.__format__).
4596
Eric Smith5a3c1352008-02-19 13:21:56 +00004597- Implemented PEP 3101, Advanced String Formatting. This adds a new
4598 builtin format(); a format() method for str and unicode; a
4599 __format__() method to object, str, unicode, int, long, float, and
4600 datetime; the class string.Formatter; and the C API
4601 PyObject_Format().
4602
Georg Brandl3ee81df2008-05-17 18:14:43 +00004603- Fixed several potential crashes, all caused by specially crafted
4604 __del__ methods exploiting objects in temporarily inconsistent
4605 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004606
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004607- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004608 prevent a possible crash: an Abstract Base Class would try to access
4609 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004610
Georg Brandl3ee81df2008-05-17 18:14:43 +00004611- Fixed repr() and str() of complex numbers with infinity or nan as
4612 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00004613
Georg Brandl3ee81df2008-05-17 18:14:43 +00004614- Clear all free lists during a gc.collect() of the highest generation
4615 in order to allow pymalloc to free more arenas. Python may give back
4616 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004617
Georg Brandl3ee81df2008-05-17 18:14:43 +00004618- Issue #2045: Fix an infinite recursion triggered when printing a
4619 subclass of collections.defaultdict, if its default_factory is set
4620 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004621
Christian Heimesf75dbef2008-02-08 00:11:31 +00004622- Fixed a minor memory leak in dictobject.c. The content of the free
4623 list was not freed on interpreter shutdown.
4624
Georg Brandl21e99f42010-03-07 15:23:59 +00004625- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004626 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004627
Georg Brandl3ee81df2008-05-17 18:14:43 +00004628- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4629 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004630 to compact the internal free lists of pre-allocted ints and floats.
4631
Georg Brandl3ee81df2008-05-17 18:14:43 +00004632- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4633 calls. Python expected the return type int but the fork familie
4634 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004635
Georg Brandl3ee81df2008-05-17 18:14:43 +00004636- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4637 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004638
Georg Brandl3ee81df2008-05-17 18:14:43 +00004639- Issue #2025: Add tuple.count() and tuple.index() methods to comply
4640 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00004641
Georg Brandl3ee81df2008-05-17 18:14:43 +00004642- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
4643 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00004644
Georg Brandl3ee81df2008-05-17 18:14:43 +00004645- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4646 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004647
Georg Brandl3ee81df2008-05-17 18:14:43 +00004648- Patch #1473257: generator objects gain a gi_code attribute. This is
4649 the same object as the func_code attribute of the function that
4650 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004651
Georg Brandl3ee81df2008-05-17 18:14:43 +00004652- Issue #1920: "while 0" statements were completely removed by the
4653 compiler, even in the presence of an "else" clause, which is
4654 supposed to be run when the condition is false. Now the compiler
4655 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004656
Guido van Rossumeead05f2008-01-24 18:21:02 +00004657- A few crashers fixed: weakref_in_del.py (issue #1377858);
4658 loosing_dict_ref.py (issue #1303614, test67.py);
4659 borrowed_ref_[34].py (not in tracker).
4660
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004661- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004662 suppressed while an extension is loaded by calling SetErrorMode in
4663 dynload_win.c. The error is still reported properly.
4664
Georg Brandl3ee81df2008-05-17 18:14:43 +00004665- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004666 several extension methods and modules do not work without unicode
4667 support.
4668
Georg Brandl26543b12008-01-21 18:36:51 +00004669- Issue #1882: when compiling code from a string, encoding cookies in the
4670 second line of code were not always recognized correctly.
4671
Georg Brandl14404b62008-01-19 19:27:05 +00004672- Issue #1679: "0x" was taken as a valid integer literal.
4673
Georg Brandl6caad7d2008-01-26 14:19:22 +00004674- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004675 added.
4676
Christian Heimesc94e2b52008-01-14 04:13:37 +00004677- sys.float_info / PyFloat_GetInfo: The floating point information
4678 object was converted from a dict to a specialized structseq object.
4679
Georg Brandl3ee81df2008-05-17 18:14:43 +00004680- Patch #1816: Added sys.flags structseq. It exposes the status of
4681 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004682
Georg Brandl3ee81df2008-05-17 18:14:43 +00004683- Objects/structseq.c: Implemented new structseq representation. The
4684 patch makes structseqs (e.g. the return value of os.stat) more
4685 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004686
Georg Brandl3ee81df2008-05-17 18:14:43 +00004687- Patch #1700288: added a type attribute cache that caches method
4688 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004689
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004690- Bug #1776: __import__() no longer accepts filenames on any platform.

4694
Georg Brandl3ee81df2008-05-17 18:14:43 +00004695- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4696 envvar and sys.dont_write_bytecode attribute. All these can be set
4697 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004698
Georg Brandl3ee81df2008-05-17 18:14:43 +00004699- Improve some exception messages when Windows fails to load an
4700 extension module. Now we get for example '%1 is not a valid Win32
4701 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004702
Georg Brandl3ee81df2008-05-17 18:14:43 +00004703- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004705- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
4706 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004707
Christian Heimes0a8143f2007-12-18 23:22:54 +00004708- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004709 and INF. float("nan"), float("inf") and float("-inf") now work on
4710 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004711
Georg Brandl3ee81df2008-05-17 18:14:43 +00004712- Compiler now generates simpler and faster code for dictionary
4713 literals. The oparg for BUILD_MAP now indicates an estimated
4714 dictionary size. There is a new opcode, STORE_MAP, for adding
4715 entries to the dictionary.

4745 file can now be directly executed by passing their name to the
4746 interpreter. The directory/zipfile is automatically inserted as the
4747 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004748
Georg Brandl3ee81df2008-05-17 18:14:43 +00004749- Issue #1265: Fix a problem with sys.settrace, if the tracing
4750 function uses a generator expression when at the same time the
4751 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004752
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004753- sets and frozensets now have an isdisjoint() method.
4754

Georg Brandl3ee81df2008-05-17 18:14:43 +00004760 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4761 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004762
Georg Brandl3ee81df2008-05-17 18:14:43 +00004763- Issue #1686386: Tuple's tp_repr did not take into account the
4764 possibility of having a self-referential tuple, which is possible
4765 from C code. Nor did object's tp_str consider that a type's tp_str
4766 could do something that could lead to an inifinite recursion.
4767 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4768 issues.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004770- Issue #1164: It was possible to trigger deadlock when using the
4771 'print' statement to write to a file since the GIL was not released
4772 as needed. Now PyObject_Print() does the right thing along with
4773 various tp_print implementations of the built-in types and those in
4774 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004775
Georg Brandl3ee81df2008-05-17 18:14:43 +00004776- Issue #1147: Exceptions were directly allowing string exceptions in
4777 their throw() method even though string exceptions no longer
4778 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004779
Georg Brandl3ee81df2008-05-17 18:14:43 +00004780- Issue #1096: Prevent a segfault from getting the repr of a very
4781 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004782
Brett Cannon1e534b52007-09-07 04:18:30 +00004783- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004784 PyObject_Call() never calling back out to Python code to trigger
4785 recursion depth updates/checks. Required the creation of a static
4786 RuntimeError instance in case normalizing an exception put the
4787 recursion check value past its limit. Fixes crashers
4788 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004789

Neal Norwitz0ac60192007-05-27 04:08:54 +00004803- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004804 __*__ attributes. (Some already existed, e.g., __doc__ and
4805 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004806
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004807- Add -3 option to the interpreter to warn about features that are
4808 deprecated and will be changed/removed in Python 3.0.
4809
Georg Brandl2134e752007-05-21 20:34:16 +00004810- Patch #1686487: you can now pass any mapping after '**' in function
4811 calls.
4812
Collin Winter62903052007-05-18 23:11:24 +00004813- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004814 "except E as target:". This is to provide forwards compatibility
4815 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004816
Brett Cannon229cee22007-05-05 01:34:02 +00004817- Deprecate BaseException.message as per PEP 352.

Vinay Sajip8549ce32007-05-06 17:53:37 +00004822- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004823 setting a plain string, ie don't expand to single letter identifiers.
4824
Raymond Hettinger13936692007-04-11 18:40:58 +00004825- Request #1191699: Slices can now be pickled.
4826
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004827- Request #1193128: str.translate() now allows a None argument for
4828 translations that only remove characters without re-mapping the
4829 remaining characters.
4830
Georg Brandl5cb76c12007-03-21 09:00:39 +00004831- Patch #1682205: a TypeError while unpacking an iterable is no longer
4832 masked by a generic one with the message "unpack non-sequence".
4833
Neal Norwitzaa754b72007-03-21 06:39:48 +00004834- Remove unused file Python/fmod.c.
4835
Guido van Rossum143b5642007-03-23 04:58:42 +00004836- Bug #1683368: The object.__init__() and object.__new__() methods are
4837 now stricter in rejecting excess arguments. The only time when
4838 either allows excess arguments is when it is not overridden and the
4839 other one is. For backwards compatibility, when both are
4840 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004841 warning later). Also, type.__init__() insists on the same signature
4842 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004843
Georg Brandl3ee81df2008-05-17 18:14:43 +00004844- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4845 object to complex using its __complex__() method before falling back
4846 to the __float__() method. Therefore, the functions in the cmath
4847 module now can operate on objects that define a __complex__()
4848 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004849
Georg Brandl3ee81df2008-05-17 18:14:43 +00004850- Patch #1623563: allow __class__ assignment for classes with

4858 ``object.__reduce_ex__()`` is called with an object that is faking
4859 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00004860
Georg Brandl3ee81df2008-05-17 18:14:43 +00004861- Patch #1680015: Don't modify __slots__ tuple if it contains an

4865
Georg Brandl7b9c5552007-03-12 14:30:05 +00004866- Bug #1678647: write a newline after printing an exception in any
4867 case, even when converting the value to a string failed.
4868
Georg Brandl871f1bc2007-03-12 13:17:36 +00004869- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004870 its argument, if it exists. If not, it will work like before. This
4871 allows customizing the output of dir() in the presence of a
4872 __getattr__().

4881 parthensized forms. This means complex(repr(x)) now works instead of
4882 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004883
Georg Brandlaa2321b2007-03-07 00:40:28 +00004884- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004885 makes the filenames the warning module prints much more sensible
4886 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00004887

Georg Brandl0fca97a2007-03-05 22:28:08 +00004899- Patch #1674228: when assigning a slice (old-style), check for the
4900 sq_ass_slice instead of the sq_slice slot.
4901
Georg Brandl3ee81df2008-05-17 18:14:43 +00004902- When printing an unraisable error, don't print exceptions. before
4903 the name. This duplicates the behavior whening normally printing
4904 exceptions.

5513 Python would crash instead of raising an error.

5532 -- the failure just occurred later, with a more cumbersome
5533 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005814- Issue #829951: In the smtplib module, SMTP.starttls() now complies
5815 with RFC 3207 and forgets any knowledge obtained from the server not
5816 obtained from the TLS negotiation itself. Patch contributed by Bill
5817 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00005818
Georg Brandl3ee81df2008-05-17 18:14:43 +00005819- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005820 that the SMTP.starttls() caller no longer needs to call ehlo()
5821 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00005822 does not claim to support starttls. Adds the
5823 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
5824 Fenner.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005866- Patch #976880: ``mmap`` objects now have an ``rfind`` method that
Andrew M. Kuchling5c60bfc2008-01-19 18:18:41 +00005867 works as expected. ``mmap.find`` also takes an optional ``end``

5904 complex, tuple, list, dict, set, and frozenset. Formerly, it would
5905 silently miscode subclasses of those types. Now, it raises a
5906 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00005907

Georg Brandl3ee81df2008-05-17 18:14:43 +00005922 time so that opening a database previously created with the DB_DUP
5923 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5924 opens. Specifically: dictionary assignment to a DB object will
5925 replace all values for a given key when the database allows
5926 duplicate values. DB users should use DB.put(k, v) when they want
5927 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005928

5934 characters with ASCII value less than 32. Also, it correctly quotes
5935 dots only if they occur on a single line, as opposed to the previous
5936 behavior of quoting dots if they are the second character of any
5937 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00005938

6260-----
6261
Georg Brandl3ee81df2008-05-17 18:14:43 +00006262- Unified naming convention for free lists and their limits. All free
6263 lists in Object/ are named ``free_list``, the counter ``numfree``
6264 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
6265 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00006266
Georg Brandl3ee81df2008-05-17 18:14:43 +00006267- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
6268 to ``PyTuple_SetItem``, it can be used to populate a brand new
6269 frozenset; but it does not steal a reference to the added item.

6274 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
6275 PyLong_FromSsize_t public functions.

6278
6279- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
6280 ``PyFloat_GetInfo()`` to the float API.
6281
Georg Brandl3ee81df2008-05-17 18:14:43 +00006282- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
6283 of w# format code incorrectly truncated the length to an int, even
6284 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
6285 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00006286
Georg Brandl3ee81df2008-05-17 18:14:43 +00006287- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
6288 Py_TYPE and Py_REFCNT.

6305- Fix some leftovers from the conversion from int to Py_ssize_t
6306 (relevant to strings and sequences of more than 2**31 items).
6307
6308- Make _PyGILState_NoteThreadState() static, it was not used anywhere
6309 outside of pystate.c and should not be necessary.
6310
Georg Brandl3ee81df2008-05-17 18:14:43 +00006311- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
6312 absolute imports. In earlier versions they might have used relative
6313 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00006314
Georg Brandl3ee81df2008-05-17 18:14:43 +00006315- Added case insensitive comparison methods ``PyOS_stricmp(char*,
6316 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00006317
Georg Brandl3ee81df2008-05-17 18:14:43 +00006318- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00006325- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
6326 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
6327 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
6328 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00006329

Georg Brandl3ee81df2008-05-17 18:14:43 +00006343- Removed the macfs module. It had been deprecated since Python 2.5.
6344 This lead to the deprecation of macostools.touched() as it relied
6345 solely on macfs and was a no-op under OS X.
