410 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +0100411 compiler optimizing the check away. Also fix similar overflow checks
412 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

Ned Deily0d0ea482012-02-10 12:59:06 +0100488- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
489 Distutils-based packages with C extension modules may fail because
490 Apple has removed gcc-4.2, the version used to build python.org
491 64-bit/32-bit Pythons. If the user does not explicitly override
492 the default C compiler by setting the CC environment variable,
493 Distutils will now attempt to compile extension modules with clang
494 if gcc-4.2 is required but not found. Also as a convenience, if
495 the user does explicitly set CC, substitute its value as the default
496 compiler in the Distutils LDSHARED configuration variable for OS X.
497 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
498 SDK, neither of which are available in Xcode 4. This change does not
499 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -0700772- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
773 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
774 interpreter process. This could cause failures in non-Distutils subprocesses
775 and was unreliable since tests or user programs could modify the interpreter
776 environment after Distutils set it. Instead, have Distutils set the the
777 deployment target only in the environment of each build subprocess. It is
778 still possible to globally override the default by setting
779 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
780 greater or equal to the default value, the value with which the interpreter
781 was built.

811 the ticker doesn't have to wind down to zero from the old starting point
812 before the new interval takes effect. And if the user increases the
813 interval, it makes sure the new limit takes effect right away rather have an
814 early task switch before recognizing the new interval.

1753 fix various SSLSocket methods to raise socket.error rather than an
1754 unhelpful TypeError when called on an unconnected socket. Original patch
1755 by Andrew Bennetts.

1764
Raymond Hettinger20397532010-09-12 02:11:45 +00001765- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
1766 This prevents user-created self-referencing ordered dictionaries from
1767 becoming permanently uncollectable GC garbage. The downside is that
1768 removing __del__ means that the internal doubly-linked list has to wait for
1769 GC collection rather than freeing memory immediately when the refcnt drops
1770 to zero.
1771

1779 original error is re-raised.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00002229- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
2230 start byte and the continuation byte(s) are now considered invalid, instead
2231 of the number of bytes specified by the start byte.
2232 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
2233 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
2234 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

2244 objects. (1) The comparison could incorrectly return True in some cases
2245 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Georg Brandlfee0f442010-05-22 21:26:21 +00002564- On Windows, ctypes does no longer check the stack before and after calling a
2565 foreign function. This allows to use the unmodified libffi library.

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00002590 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
2591 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
2592 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

2612Core and Builtins
2613-----------------
2614
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00002615- Issue #7301: Add environment variable $PYTHONWARNINGS.
2616
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00002617- Issue #8329: Don't return the same lists from select.select when no fds are
2618 changed.
2619
Georg Brandlfee0f442010-05-22 21:26:21 +00002620- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00002621 on 64-bit machines. The shift count for either left or right shift is
2622 permitted to be up to sys.maxsize.
2623
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00002624- Ensure that tokenization of identifiers is not affected by locale.
2625
Georg Brandlfee0f442010-05-22 21:26:21 +00002626- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00002627
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00002628- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
2629
Georg Brandlfee0f442010-05-22 21:26:21 +00002630- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2631 with a non-empty format string. This is an effort to future-proof user
2632 code. If a derived class does not currently implement __format__ but later
2633 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002634 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002635 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00002636
Antoine Pitroua57df2c2010-03-31 21:32:15 +00002637- Issue #8268: Old-style classes (not just instances) now support weak

2646 arguments to a function correct.
2647
Benjamin Peterson0dee9c12010-03-17 20:41:42 +00002648- Issue #8164: Don't allow lambda functions to have a docstring.
2649
Victor Stinner66644262010-03-10 22:30:19 +00002650- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00002651 (SIGINT). If an error occurs while importing the site module, the error is
2652 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +00002653 module.

2667
Georg Brandlfee0f442010-05-22 21:26:21 +00002668- Issue #8257: The Decimal construct now accepts a float instance directly,
2669 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00002670
2671 >>> Decimal(1.1)
2672 Decimal('1.100000000000000088817841970012523233890533447265625')
2673
Raymond Hettinger34c35b22010-04-03 10:22:00 +00002674- collections.Counter() now supports a subtract() method.
2675
Georg Brandlfee0f442010-05-22 21:26:21 +00002676- The functools module now has a total_ordering() class decorator to simplify
2677 the specification of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +00002678
Georg Brandlfee0f442010-05-22 21:26:21 +00002679- The functools module also adds cmp_to_key() as a tool to transition old-style
2680 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00002681
Georg Brandlfee0f442010-05-22 21:26:21 +00002682- Issue #8294: The Fraction constructor now accepts Decimal and float instances
2683 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00002684
Georg Brandlfee0f442010-05-22 21:26:21 +00002685- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
2686 InvalidOperation instead of returning False. (Comparisons involving a quiet
2687 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2688 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00002689
Georg Brandlfee0f442010-05-22 21:26:21 +00002690- Issue #2531: Comparison operations between floats and Decimal instances now
2691 return a result based on the numeric values of the operands; previously they
2692 returned an arbitrary result based on the relative ordering of id(float) and
2693 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00002694
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002695- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00002696 argument `-` which tells it to read files to compile from stdin. Each line is
2697 read on demand and the named file is compiled immediately. (Original patch by
2698 Piotr Ożarowski).
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002699
Georg Brandlfee0f442010-05-22 21:26:21 +00002700- Issue #3135: Add ``inspect.getcallargs()``, which binds arguments to a

Florent Xicluna58b65662010-03-30 16:29:03 +00002703- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
2704 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00002705 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00002706
Georg Brandlfee0f442010-05-22 21:26:21 +00002707- Comparisons using one of <, <=, >, >= between a complex instance and a
2708 Fractions instance now raise TypeError instead of returning True/False. This
2709 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2710 <=> complex, and complex <=> complex comparisons.
Mark Dickinson9588d992010-03-27 11:14:37 +00002711

Antoine Pitrou513d9ae2010-03-22 19:59:46 +00002721- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
Georg Brandlfee0f442010-05-22 21:26:21 +00002722 didn't support chflags() (for example ZFS under FreeBSD). The error is now
2723 silenced.

2815 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the

Georg Brandlfee0f442010-05-22 21:26:21 +00002817 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
2818 inconsistent: __int__ was used for some integer codes but not for others, and
2819 the set of integer codes for which it was used differed between native packing
2820 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00003032- Issue #7712: test_support gained a new ``temp_cwd`` context manager which is
3033 now also used by regrtest to run all the tests in a temporary directory. The
3034 original CWD is saved in ``test.test_support.SAVEDCWD``. Thanks to Florent
3035 Xicluna who helped with the patch.

3073 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
3074 returning NULL. The macro now returns a statically allocated empty string
3075 instead.

Georg Brandlba83f822010-03-14 09:50:54 +00003128 file position when calling `truncate()`. It would previously change the file
3129 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003130 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
3131

3133 class used to represent files stored inside an archive. The new
3134 implementation is significantly faster and can be wrapped in a
3135 ``io.BufferedReader`` object for more speedups. It also solves an issue
3136 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
3137 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +00003147- Issue #7748: Since unicode values are supported for some metadata options in
3148 Distutils, the DistributionMetadata get_* methods will now return an utf-8
3149 encoded string for them. This ensures that the upload and register commands
3150 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00003227- The ``__complex__()`` method is now looked up on the class of instances to
3228 make it consistent with other special methods.

3232
Mark Dickinson1b34d252010-01-01 17:27:30 +00003233- Issue #5080: A number of functions and methods previously produced a

3235 These functions and methods now raise TypeError instead. The majority of the
3236 effects of this change are in the extension modules, but some core functions
3237 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3238 and many unicode/str methods.

3254 internal representation of a long.

3262
Georg Brandlba83f822010-03-14 09:50:54 +00003263 These executables now work properly with the arch(1) command: ``arch -ppc
3264 python`` will start a universal binary version of python in PPC mode (unlike

Georg Brandlba83f822010-03-14 09:50:54 +00003421- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3422 decimal string that's guaranteed to round back to x under correct rounding
3423 (with round-half-to-even rounding mode). Previously it gave a string based on
3424 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3425 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3426 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003427
Georg Brandlba83f822010-03-14 09:50:54 +00003428- Issue #7117: On almost all platforms: float-to-string and string-to-float
3429 conversions within Python are now correctly rounded. Places these conversions
3430 occur include: str for floats and complex numbers; the float and complex
3431 constructors; old-style and new-style numeric formatting; serialization and
3432 deserialization of floats and complex numbers using marshal, pickle and json;
3433 parsing of float and imaginary literals in Python code; Decimal-to-float
3434 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003435
Georg Brandlba83f822010-03-14 09:50:54 +00003436 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3437 providing correctly-rounded strtod and dtoa C functions. This code is
3438 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3439 the C compiler. There may be a small number of platforms on which correct
3440 operation of this code cannot be guaranteed, so the code is not used: notably,
3441 this applies to platforms where the C double format is not IEEE 754 binary64,
3442 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3443 and Python's configure script is unable to determine how to change the FPU
3444 precision. On these platforms conversions use the platform strtod and dtoa,
3445 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00003447- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3448 uses the correctly-rounded string <-> float conversions described above (when
3449 available), and so produces correctly rounded results that will display nicely
3450 under the float repr. There are two related small changes: (1) round now
3451 accepts any class with an ``__index__()`` method for its second argument (but
3452 no longer accepts floats for the second argument), and (2) an excessively
3453 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3454 raises an exception.

3598 (2) parsing of strings representing infinities and nans was locale aware; and
3599 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00003601- Issue #5920: For ``float.__format__()``, change the behavior with the empty
3602 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
3603 but with at least one decimal point and with a default precision
3604 of 12. Previously, the behavior the same but with a default precision of 6.
3605 This more closely matches ``str()``, and reduces surprises when adding
3606 alignment flags to the empty presentation type. This also affects the new
3607 complex.__format__ in the same way.
3608
3609- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

3740 collecting the oldest generation) so that allocating lots of objects without
3741 destroying them does not show quadratic performance. Based on a proposal by

3746
Georg Brandlba83f822010-03-14 09:50:54 +00003747- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
3748 existing .py counterpart, override the co_filename attributes of all code
3749 objects if the original filename is obsolete (which can happen if the file has
3750 been renamed, moved, or if it is accessed through different paths). Patch by
3751 Ziga Seilnacht and Jean-Paul Calderone.

Georg Brandl6425a2f2008-12-28 11:54:53 +00003770- Issue #4759: None is now allowed as the first argument of
Georg Brandlba83f822010-03-14 09:50:54 +00003771 ``bytearray.translate()``. It was always allowed for ``bytes.translate()``.

Skip Montanarof205c132008-12-23 03:30:15 +00003773- Added test case to ensure attempts to read from a file opened for writing

Georg Brandlba83f822010-03-14 09:50:54 +00003790- Issue #4445: Replace ``sizeof(PyStringObject)`` with
3791 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
3792 instances. On a typical machine this saves 3 bytes of memory (on average) per
3793 string allocation.

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00003795- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
3796 interpreter to abort ("Fatal Python error: Could not reset the stack!")
3797 instead of throwing a MemoryError.
3798
Georg Brandlba83f822010-03-14 09:50:54 +00003799- Issue #3689: The list reversed iterator now supports __length_hint__ instead
3800 of __len__. Behavior now matches other reversed iterators.

Benjamin Petersonc078f922008-11-21 22:27:24 +00003802- Issue #4367: Python would segfault during compiling when the unicodedata

3804
Georg Brandlba83f822010-03-14 09:50:54 +00003805- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
3806 file objects with closefd=False. The file descriptor is still kept open but
3807 the file object behaves like a closed file. The ``FileIO`` object also got a
3808 new readonly attribute ``closefd``.

Benjamin Peterson46cc6d12008-11-19 21:49:09 +00003810- Issue #4348: Some bytearray methods returned that didn't cause any change to
3811 the bytearray, returned the same bytearray instead of a copy.
3812
Georg Brandlba83f822010-03-14 09:50:54 +00003813- Issue #4317: Fixed a crash in the ``imageop.rgb2rgb8()`` function.

Benjamin Petersonbdca9422008-10-26 20:21:13 +00003825- Issue #4209: Enabling unicode_literals and the print_function in the same
3826 __future__ import didn't work.
3827
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00003828- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00003829 because it is a reserved word in 3.x.

Georg Brandlba83f822010-03-14 09:50:54 +00003831- On windows, ``os.chdir()`` given unicode was not working if
3832 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
3833 this code path is really executed because I cannot move to such directory on
3834 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00003835
Georg Brandlba83f822010-03-14 09:50:54 +00003836- Issue #4069: When ``set.remove(element)`` is used with a set element, the
3837 element is temporarily replaced with an equivalent frozenset. But the
3838 eventual KeyError would always report the empty ``frozenset()`` as the missing
3839 key. Now it correctly refers to the initial element.

3857 returned them on 64bit platforms.
3858
Walter Dörwalded960ac2009-05-03 22:36:33 +00003859- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
3860 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
3861 step. This avoids problems with counting UTF-8 bytes that ignores the effect
3862 of using the replace error handler in PyUnicode_DecodeUTF8().
3863
Walter Dörwald726ba8e2009-05-06 14:32:35 +00003864- Issue #3739: The unicode-internal encoder now reports the number of characters
3865 consumed like any other encoder (instead of the number of bytes).
3866
Georg Brandlba83f822010-03-14 09:50:54 +00003867- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
3868 allocator will be automatically disabled when running under Valgrind. This
3869 gives improved memory leak detection when running under Valgrind, while taking
3870 advantage of pymalloc at other times.

5101 __all__ attribute, rather than using a hardcoded and incomplete list.
5102
R. David Murray14dcd432009-10-14 13:58:07 +00005103- Issue #7058: Added save/restore for things like sys.argv and cwd to
5104 runtest_inner in regrtest, with warnings if the called test modifies them,
5105 and a new section in the summary report at the end.

Brett Cannone7e941e2009-09-03 21:25:21 +00005109- Issue #6806: test_platform failed under OS X 10.6.0 because ``sw_ver`` leaves
5110 off the trailing 0 in the version number.

Guilherme Polo7f146ab2009-06-21 17:22:50 +00005112- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
5113 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00005114 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
5115 the tests if DISPLAY is defined but can't be used.

Antoine Pitrou4698d992009-05-31 14:20:14 +00005117- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
5118 regression tests in parallel, shortening the total runtime.
5119
Georg Brandlba83f822010-03-14 09:50:54 +00005120- Issue #5354: New test support function import_fresh_module() makes it easy to
5121 import both normal and optimised versions of modules. test_heapq and
5122 test_warnings have been adjusted to use it, tests for other modules with both
5123 C and Python implementations in the stdlib can be adjusted to use it over
5124 time.

5131
Georg Brandlba83f822010-03-14 09:50:54 +00005132- regrtest no longer treats ImportError as equivalent to SkipTest. Imports that
5133 should cause a test to be skipped are now done using import_module from test
5134 support, which does the conversion.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00005235- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
5236
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005237- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5238 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5239 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5240 ``printf`` function, whereas PyString_FromFormat has an independent
5241 implementation and uses "%zd" on all platforms for size_t values.
5242 This makes a difference on win64, where ``printf`` needs "%Id" to display
5243 64bit values.
5244
Benjamin Peterson97179b02008-09-09 20:55:01 +00005245- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

5249 object; previously an int would be returned for small values. the __long__
5250 method is allowed to return either an int or a long, but the behaviour of
5251 float objects should not change to respect backward compatibility.
5252
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00005253- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +00005259 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005260 was correctly parsed but parsing of subsequent arguments failed.
5261
Vinay Sajip35e3b032008-09-01 14:33:59 +00005262- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005263 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5264 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5265 when given a tuple of classes as second argument, were looking up
5266 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5267 type object.
5268
Neal Norwitz18aa3882008-08-24 05:04:52 +00005269- Fix crashes on memory allocation failure found with failmalloc.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005406What's New in Python 2.6 beta 3?
5407================================
5408
Barry Warsaw07a4a382008-08-21 01:15:08 +00005409*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005410
5411Core and Builtins
5412-----------------
5413
Guido van Rossumf8402962008-08-20 15:01:50 +00005414- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5415 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5416 extensions do not automatically benefit from the class attribute
5417 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5418 to their tp_flags field if they care. This is a backwards
5419 compatibility feature; in 3.0, all types will use the cache by
5420 default.
5421
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005422- Keyword arguments can now follow starred arguments. (``f(a, *args,
5423 keyword=23)`` is now valid syntax.)
5424
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005425- ctypes function pointers that are COM methods have a boolean True
5426 value again.
5427
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005428- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5429 by denying s# to parse objects that have a releasebuffer procedure,
5430 and introducing s*.
5431
Georg Brandl1e13ea92008-08-11 09:07:59 +00005432- Issue #3537: Fix an assertion failure when an empty but presized dict
5433 object was stored in the freelist.
5434
Mark Dickinsonb6467572008-08-04 21:30:09 +00005435- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5436 ValueError consistently across platforms.
5437
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005438- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5439 (64bit Unix, for example), unichr() would truncate its argument and return
5440 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5441
Neal Norwitze7d8be82008-07-31 17:17:14 +00005442- Apply security patches from Apple.
5443
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005444- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5445 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5446
Antoine Pitrou92f82162008-07-25 22:22:08 +00005447- Issue #1819: function calls with several named parameters are now on
5448 average 35% faster (as measured by pybench).
5449
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005450- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5451 the python debugger steps into a class statement: the free variables (local
5452 variables defined in an outer scope) would be deleted from the outer scope.
5453
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005454- Issue #2620: Overflow checking when allocating or reallocating memory
5455 was not always being done properly in some python types and extension
5456 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5457 all been updated to perform better checks and places in the code that
5458 would previously leak memory on the error path when such an allocation
5459 failed have been fixed.

5462-------
5463
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00005464- Issue #3612: Added some missing basic types in ctypes.wintypes.
5465
Benjamin Petersone977ad42008-08-20 01:42:01 +00005466- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5467 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5468
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005469- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5470 version reported by these tools does not necessarily follow the python
5471 version numbering scheme, so the module is less strict when parsing it.
5472
Nick Coghlanf70385a2008-08-18 12:42:46 +00005473- Issue #2235: Added Py3k warnings for types which will become unhashable
5474 under the stricter __hash__ inheritance rules in 3.0. Several types
5475 which did not meet the rules for hash invariants and were already
5476 unhashable in 3.0 have now been explicitly flagged as unhashable in
5477 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5478 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5479
Brett Cannon88f801d2008-08-18 00:46:22 +00005480- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
5481 imported into the module but exposed as part of the module's API.
5482
Brett Cannon7b96f072008-08-18 00:41:11 +00005483- Remove an unneeded import of abc.ABCMeta from 'inspect'.
5484
Brett Cannon46225e72008-08-18 00:36:52 +00005485- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
5486
Brett Cannon25c9d6a2008-08-17 22:10:11 +00005487- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
5488
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005489- Issue #3575: Incremental decoder's decode function now takes bytearray
5490 by using 's*' instead of 't#'.
5491
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00005492- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00005493 fails unicode conversion on 2nd parameter. (windows only)
5494
Georg Brandl222e2082010-08-01 22:27:39 +00005495- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00005496 in a redirect.
5497
Brett Cannonabe423e2008-08-16 21:47:07 +00005498- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00005499 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00005500
Facundo Batistaeb90b782008-08-16 14:44:07 +00005501- Issue #2776: fixed small issue when handling an URL with double slash
5502 after a 302 response in the case of not going through a proxy.
5503
Antoine Pitroub90a8be2008-08-15 21:03:21 +00005504- Issue #2676: in the email package, content-type parsing was hanging on
5505 pathological input because of quadratic or exponential behaviour of a
5506 regular expression.
5507
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00005508- Issue #3476: binary buffered reading through the new "io" library is now
5509 thread-safe.
5510
Brett Cannonbf3157b2008-08-14 05:00:03 +00005511- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5512 since mimetools itself is deprecated. Because modules are cached, all
5513 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5514
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00005515- Issue #3134: shutil referenced undefined WindowsError symbol.
5516
Robert Schuppenies14646332008-08-10 11:01:53 +00005517- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
5518 menu entries were not deleted.
5519
Brett Cannon83e81842008-08-09 23:30:55 +00005520- Copied the implementation of reduce() to _functools.reduce() to have a
5521 version that did not raise a DeprecationWarning under -3.
5522
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00005523- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
5524 a MemoryError rather than silently stop the iteration.
5525
Guido van Rossum59ce9012008-08-09 14:55:34 +00005526- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5527 to _sre.compile() will now be rejected. This should not affect anybody
5528 since the re.compile() function never generates invalid re-bytecode.
5529
Skip Montanaroa032bf42008-08-08 22:52:51 +00005530- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5531 upon first access it can be automatically initialized from the csv file if
5532 it wasn't initialized during instantiation.
5533
Brett Cannon3aa2a492008-08-06 22:28:09 +00005534- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5535 the reload() built-in has been removed.
5536
Brett Cannon7e30b672008-08-04 21:52:25 +00005537- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00005538 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Brett Cannon7e30b672008-08-04 21:52:25 +00005544
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00005545- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
5546 raised an AttributeError.
5547
Benjamin Peterson01a24322008-07-28 23:35:27 +00005548- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00005549 asking for a specific length. This problem only affected files opened
5550 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00005551
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00005552- Issue #3449: Update decimal module to use most recent specification
5553 (v. 1.68) and tests (v. 2.58) from IBM.
5554
Georg Brandl222e2082010-08-01 22:27:39 +00005555- Issue #3437: Bug fix in robotparser parsing of Allow: lines.
Skip Montanarof9ac43f2008-07-27 00:50:41 +00005556

5559
Georg Brandlf9efabb2008-07-23 15:16:45 +00005560- Deprecate the "ast" parser function aliases.
5561
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005562- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
5563
5564- Issue #3303: Fix a crash in locale.strcoll() when calling it with
5565 invalid arguments.
5566
5567- Issue #3302: Fix several crashes when calling locale's gettext functions
5568 with None arguments.
5569
5570- Issue #3389: Allow resolving dotted names for handlers in logging
5571 configuration files.
5572
5573- Deprecate the sunaudio module for removal in Python 3.0.
5574
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00005575- Issue #3394: zipfile.writestr sets external attributes when passed a
5576 file name rather than a ZipInfo instance, so files are extracted with
5577 mode 0600 rather than 000 under Unix.
5578
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00005579- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
5580 argument in python 2.5, this broke code that subclassed Popen to include its
5581 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00005591- Issue #2235: the C API function PyObject_HashNotImplemented and its
5592 interaction with the tp_hash slot (added in 2.6b2) are now documented
5593
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00005594- Issue #643841: The language reference now provides more detailed
5595 coverage of the lookup process for special methods. The disclaimers
5596 regarding lack of coverage of new-style classes have also been
5597 removed, since the coverage is now fairly reasonable.

5602
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005603*Release date: 17-Jul-2008*

5606-----------------
5607
Georg Brandl3e483f62008-07-16 22:57:41 +00005608- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5609 its methods now allow for items objects that can be converted to
5610 an integer using operator.index().
5611
Mark Dickinson64b7e502008-07-16 09:40:03 +00005612- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5613 produced a ValueError instead of giving the correct float.
5614
Eric Smitha5fa5a22008-07-16 00:11:49 +00005615- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5616 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5617
Mark Dickinson7103aa42008-07-15 19:08:33 +00005618- Issue #3008: the float type has a new instance method 'float.hex'
5619 and a new class method 'float.fromhex' to convert floating-point
5620 numbers to and from hexadecimal strings, respectively.
5621
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005622- Issue #2235: __hash__ is once again inherited by default. To allow
5623 collections.Hashable to remain meaningful in the presence of the
5624 default hash implementation (object.__hash__), it is now possible
5625 to explicit block inheritance of hash by setting __hash__=None at
5626 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5627 level.
5628
Nick Coghlanb028f502008-07-13 14:52:36 +00005629- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5630 the parent module cannot be found while performing an absolute import.
5631 This means that an incorrectly defined __package__ attribute will
5632 now only prevent relative imports in that module rather than causing
5633 all imports from that module to fail.
5634
Nick Coghlan14ff9942008-07-08 14:21:42 +00005635- Issue #2517: Allow unicode messages in Exceptions again by correctly
5636 bypassing the instance dictionary when looking up __unicode__ on
5637 new-style classes.
5638
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00005639- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
5640 set to a custom object whose write() method happens to install
5641 another file in sys.stdout.

5645 another thread's dictionary.
5646
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005647- Issue #3004: Minor change to slice.indices(): the start and stop
5648 arguments are now treated identically, making the behaviour easier
5649 to describe and understand. For example, slice(None, -10,
5650 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5651 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5652 10, -1).
5653
Georg Brandl278fc502008-07-19 12:46:12 +00005654- Issue #3219: Calling a function with repeated keyword arguments,
5655 f(a=2, a=23), would not cause a syntax error. This was a regression
5656 from 2.4 caused by the switch to the new compiler.

Georg Brandl5cc774e2008-06-11 20:28:06 +00006106 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006107
6108 This is controlled by the configure argument ``--with-universal-archs``:
6109
6110 - ``--with-universal-archs=all``: install 4-way universal
6111
6112 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6113
6114 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6115
6116 This option should be used in combination with ``--enable-universalsdk=``.
6117
6118 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00006168- Issue #1631171: Re-implement the 'warnings' module in C (the
6169 original Python code has been kept as backup). This will allow for
6170 using the 'warning's machinery in such places as the parser where
6171 use of pure Python code is not possible. Both the ``showarning()``
6172 and ``formatwarning()`` gain an optional 'line' argument which is
6173 not called by default for backwards-compatibility reasons. Setting
6174 ``warnings.showwarning()`` to an implementation that lacks support
6175 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006217- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00006218 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00006230- Issue #2385: distutils.core.run_script() makes __file__ available,
6231 so the controlled environment will more closely mirror the typical
6232 script environment. This supports setup.py scripts that refer to
6233 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006238- Issue #2550: The approach used by client/server code for obtaining
6239 ports to listen on in network-oriented tests has been refined in an
6240 effort to facilitate running multiple instances of the entire
6241 regression test suite in parallel without issue.
6242 test_support.bind_port() has been fixed such that it will always
6243 return a unique port -- which wasn't always the case with the
6244 previous implementation, especially if socket options had been set
6245 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6246 new implementation of bind_port() will actually raise an exception
6247 if it is passed an AF_INET/SOCK_STREAM socket with either the
6248 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6249 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6250 the socket it's been passed. This currently only applies to
6251 Windows. This option prevents any other sockets from binding to the
6252 host/port we've bound to, thus removing the possibility of the
6253 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6254 when a second SOCK_STREAM socket binds and accepts to a host/port
6255 that's already been bound by another socket. The optional preferred
6256 port parameter to bind_port() has been removed. Under no
6257 circumstances should tests be hard coding ports!
6258
6259 test_support.find_unused_port() has also been introduced, which will
6260 pass a temporary socket object to bind_port() in order to obtain an
6261 unused port. The temporary socket object is then closed and
6262 deleted, and the port is returned. This method should only be used
6263 for obtaining an unused port in order to pass to an external program
6264 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6265 a parameter to a server-oriented class that doesn't give you direct
6266 access to the underlying socket used.
6267
6268 Finally, test_support.HOST has been introduced, which should be used
6269 for the host argument of any relevant socket calls (i.e. bind and
6270 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006271
6272 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006273 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006274 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6275 test_asynchat and test_socket_ssl.
6276
Georg Brandl3ee81df2008-05-17 18:14:43 +00006277 It is now possible for multiple instances of the regression test
6278 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00006557- Added the future_builtins module, which contains hex() and oct().
6558 These are the PEP 3127 version of these functions, designed to be
6559 compatible with the hex() and oct() builtins from Python 3.0. They
6560 differ slightly in their output formats from the existing, unchanged
6561 Python 2.6 builtins. The expected usage of the future_builtins
6562 module is:
6563 from future_builtins import hex, oct
6564
Eric Smith7ef40bf2008-02-20 23:34:22 +00006565- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6566 exponents for exponents with absolute value < 100. Follows C99
6567 standard. This is a change on Windows, which would use 3 digits.
6568 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6569 so that any alterations it does to the resulting string will be
6570 available in stringlib/formatter.h (for float.__format__).
6571
Eric Smith5a3c1352008-02-19 13:21:56 +00006572- Implemented PEP 3101, Advanced String Formatting. This adds a new
6573 builtin format(); a format() method for str and unicode; a
6574 __format__() method to object, str, unicode, int, long, float, and
6575 datetime; the class string.Formatter; and the C API
6576 PyObject_Format().
6577
Georg Brandl3ee81df2008-05-17 18:14:43 +00006578- Fixed several potential crashes, all caused by specially crafted
6579 __del__ methods exploiting objects in temporarily inconsistent
6580 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006581
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006582- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006583 prevent a possible crash: an Abstract Base Class would try to access
6584 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00006585
Georg Brandl3ee81df2008-05-17 18:14:43 +00006586- Fixed repr() and str() of complex numbers with infinity or nan as
6587 real or imaginary part.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006589- Clear all free lists during a gc.collect() of the highest generation
6590 in order to allow pymalloc to free more arenas. Python may give back
6591 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006592
Georg Brandl3ee81df2008-05-17 18:14:43 +00006593- Issue #2045: Fix an infinite recursion triggered when printing a
6594 subclass of collections.defaultdict, if its default_factory is set
6595 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006596
Christian Heimesf75dbef2008-02-08 00:11:31 +00006597- Fixed a minor memory leak in dictobject.c. The content of the free
6598 list was not freed on interpreter shutdown.
6599
Georg Brandl21e99f42010-03-07 15:23:59 +00006600- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00006601 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00006602
Georg Brandl3ee81df2008-05-17 18:14:43 +00006603- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6604 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006605 to compact the internal free lists of pre-allocted ints and floats.
6606
Georg Brandl3ee81df2008-05-17 18:14:43 +00006607- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6608 calls. Python expected the return type int but the fork familie
6609 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006610
Georg Brandl3ee81df2008-05-17 18:14:43 +00006611- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00006623- Patch #1473257: generator objects gain a gi_code attribute. This is
6624 the same object as the func_code attribute of the function that
6625 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006626
Georg Brandl3ee81df2008-05-17 18:14:43 +00006627- Issue #1920: "while 0" statements were completely removed by the
6628 compiler, even in the presence of an "else" clause, which is
6629 supposed to be run when the condition is false. Now the compiler
6630 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006631
Guido van Rossumeead05f2008-01-24 18:21:02 +00006632- A few crashers fixed: weakref_in_del.py (issue #1377858);
6633 loosing_dict_ref.py (issue #1303614, test67.py);
6634 borrowed_ref_[34].py (not in tracker).
6635
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006636- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006637 suppressed while an extension is loaded by calling SetErrorMode in
6638 dynload_win.c. The error is still reported properly.
6639
Georg Brandl3ee81df2008-05-17 18:14:43 +00006640- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006641 several extension methods and modules do not work without unicode
6642 support.
6643
Georg Brandl26543b12008-01-21 18:36:51 +00006644- Issue #1882: when compiling code from a string, encoding cookies in the
6645 second line of code were not always recognized correctly.
6646
Georg Brandl14404b62008-01-19 19:27:05 +00006647- Issue #1679: "0x" was taken as a valid integer literal.
6648
Georg Brandl6caad7d2008-01-26 14:19:22 +00006649- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006650 added.
6651
Christian Heimesc94e2b52008-01-14 04:13:37 +00006652- sys.float_info / PyFloat_GetInfo: The floating point information
6653 object was converted from a dict to a specialized structseq object.
6654
Georg Brandl3ee81df2008-05-17 18:14:43 +00006655- Patch #1816: Added sys.flags structseq. It exposes the status of
6656 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006657
Georg Brandl3ee81df2008-05-17 18:14:43 +00006658- Objects/structseq.c: Implemented new structseq representation. The
6659 patch makes structseqs (e.g. the return value of os.stat) more
6660 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006661
Georg Brandl3ee81df2008-05-17 18:14:43 +00006662- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00006684 and INF. float("nan"), float("inf") and float("-inf") now work on
6685 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006686
Georg Brandl3ee81df2008-05-17 18:14:43 +00006687- Compiler now generates simpler and faster code for dictionary
6688 literals. The oparg for BUILD_MAP now indicates an estimated
6689 dictionary size. There is a new opcode, STORE_MAP, for adding
6690 entries to the dictionary.

Georg Brandl21e99f42010-03-07 15:23:59 +00006734- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006735 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6736 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006737
Georg Brandl3ee81df2008-05-17 18:14:43 +00006738- Issue #1686386: Tuple's tp_repr did not take into account the
6739 possibility of having a self-referential tuple, which is possible
6740 from C code. Nor did object's tp_str consider that a type's tp_str
6741 could do something that could lead to an inifinite recursion.
6742 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6743 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006744
Georg Brandl3ee81df2008-05-17 18:14:43 +00006745- Issue #1164: It was possible to trigger deadlock when using the
6746 'print' statement to write to a file since the GIL was not released
6747 as needed. Now PyObject_Print() does the right thing along with
6748 various tp_print implementations of the built-in types and those in
6749 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006750
Georg Brandl3ee81df2008-05-17 18:14:43 +00006751- Issue #1147: Exceptions were directly allowing string exceptions in
6752 their throw() method even though string exceptions no longer
6753 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00006754
Georg Brandl3ee81df2008-05-17 18:14:43 +00006755- Issue #1096: Prevent a segfault from getting the repr of a very
6756 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00006757
Brett Cannon1e534b52007-09-07 04:18:30 +00006758- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006759 PyObject_Call() never calling back out to Python code to trigger
6760 recursion depth updates/checks. Required the creation of a static
6761 RuntimeError instance in case normalizing an exception put the
6762 recursion check value past its limit. Fixes crashers
6763 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00006764

Neal Norwitz0ac60192007-05-27 04:08:54 +00006778- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006779 __*__ attributes. (Some already existed, e.g., __doc__ and
6780 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006781
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00006782- Add -3 option to the interpreter to warn about features that are
6783 deprecated and will be changed/removed in Python 3.0.
6784
Georg Brandl2134e752007-05-21 20:34:16 +00006785- Patch #1686487: you can now pass any mapping after '**' in function
6786 calls.
6787
Collin Winter62903052007-05-18 23:11:24 +00006788- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006789 "except E as target:". This is to provide forwards compatibility
6790 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00006797- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006798 setting a plain string, ie don't expand to single letter identifiers.
6799
Raymond Hettinger13936692007-04-11 18:40:58 +00006800- Request #1191699: Slices can now be pickled.
6801
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006802- Request #1193128: str.translate() now allows a None argument for
6803 translations that only remove characters without re-mapping the
6804 remaining characters.
6805
Georg Brandl5cb76c12007-03-21 09:00:39 +00006806- Patch #1682205: a TypeError while unpacking an iterable is no longer

6810
Guido van Rossum143b5642007-03-23 04:58:42 +00006811- Bug #1683368: The object.__init__() and object.__new__() methods are
6812 now stricter in rejecting excess arguments. The only time when
6813 either allows excess arguments is when it is not overridden and the
6814 other one is. For backwards compatibility, when both are
6815 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006816 warning later). Also, type.__init__() insists on the same signature
6817 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00006818
Georg Brandl3ee81df2008-05-17 18:14:43 +00006819- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6820 object to complex using its __complex__() method before falling back
6821 to the __float__() method. Therefore, the functions in the cmath
6822 module now can operate on objects that define a __complex__()
6823 method.
Georg Brandl2b869942007-03-17 16:08:45 +00006824
Georg Brandl3ee81df2008-05-17 18:14:43 +00006825- Patch #1623563: allow __class__ assignment for classes with

6827 same slot names.

6834 its type.

6840
Georg Brandl7b9c5552007-03-12 14:30:05 +00006841- Bug #1678647: write a newline after printing an exception in any
6842 case, even when converting the value to a string failed.
6843
Georg Brandl871f1bc2007-03-12 13:17:36 +00006844- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006845 its argument, if it exists. If not, it will work like before. This
6846 allows customizing the output of dir() in the presence of a
6847 __getattr__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00006855- Patch #1491866: change the complex() constructor to allow
6856 parthensized forms. This means complex(repr(x)) now works instead of
6857 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006858
Georg Brandlaa2321b2007-03-07 00:40:28 +00006859- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006860 makes the filenames the warning module prints much more sensible
6861 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00006862

Georg Brandl0fca97a2007-03-05 22:28:08 +00006874- Patch #1674228: when assigning a slice (old-style), check for the
6875 sq_ass_slice instead of the sq_slice slot.
6876
Georg Brandl3ee81df2008-05-17 18:14:43 +00006877- When printing an unraisable error, don't print exceptions. before
6878 the name. This duplicates the behavior whening normally printing
6879 exceptions.

7507 -- the failure just occurred later, with a more cumbersome
7508 exception.

7721 partial fix for Bug #1574584.
7722
Georg Brandl3ee81df2008-05-17 18:14:43 +00007723- Fix turtle so that time.sleep is imported for the entire library.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007789- Issue #829951: In the smtplib module, SMTP.starttls() now complies
7790 with RFC 3207 and forgets any knowledge obtained from the server not
7791 obtained from the TLS negotiation itself. Patch contributed by Bill
7792 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00007793
Georg Brandl3ee81df2008-05-17 18:14:43 +00007794- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00007795 that the SMTP.starttls() caller no longer needs to call ehlo()
7796 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00007797 does not claim to support starttls. Adds the
7798 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
7799 Fenner.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007841- Patch #976880: ``mmap`` objects now have an ``rfind`` method that
Andrew M. Kuchling5c60bfc2008-01-19 18:18:41 +00007842 works as expected. ``mmap.find`` also takes an optional ``end``

Georg Brandl3ee81df2008-05-17 18:14:43 +00007853- itertools.chain() now has an alternate constructor,

7879 complex, tuple, list, dict, set, and frozenset. Formerly, it would
7880 silently miscode subclasses of those types. Now, it raises a
7881 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00007882

Georg Brandl3ee81df2008-05-17 18:14:43 +00007897 time so that opening a database previously created with the DB_DUP
7898 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7899 opens. Specifically: dictionary assignment to a DB object will
7900 replace all values for a given key when the database allows
7901 duplicate values. DB users should use DB.put(k, v) when they want
7902 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00007903

7909 characters with ASCII value less than 32. Also, it correctly quotes
7910 dots only if they occur on a single line, as opposed to the previous
7911 behavior of quoting dots if they are the second character of any
7912 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00007913

8235-----
8236
Georg Brandl3ee81df2008-05-17 18:14:43 +00008237- Unified naming convention for free lists and their limits. All free
8238 lists in Object/ are named ``free_list``, the counter ``numfree``
8239 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
8240 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00008241
Georg Brandl3ee81df2008-05-17 18:14:43 +00008242- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
8243 to ``PyTuple_SetItem``, it can be used to populate a brand new
8244 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00008245
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008246- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

8249 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
8250 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008251
8252- Patch #1720595: add T_BOOL to the range of structmember types.
8253
8254- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
8255 ``PyFloat_GetInfo()`` to the float API.
8256
Georg Brandl3ee81df2008-05-17 18:14:43 +00008257- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
8258 of w# format code incorrectly truncated the length to an int, even
8259 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
8260 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008261
Georg Brandl3ee81df2008-05-17 18:14:43 +00008262- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
8263 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008265- PEP 3123: Provide forward compatibility with Python 3.0, while
8266 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
8267 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008268
Georg Brandl3ee81df2008-05-17 18:14:43 +00008269- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
8270 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008271
8272- Patch #1733960: Allow T_LONGLONG to accept ints.

8279
8280- Fix some leftovers from the conversion from int to Py_ssize_t
8281 (relevant to strings and sequences of more than 2**31 items).
8282
8283- Make _PyGILState_NoteThreadState() static, it was not used anywhere
8284 outside of pystate.c and should not be necessary.
8285
Georg Brandl3ee81df2008-05-17 18:14:43 +00008286- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
8287 absolute imports. In earlier versions they might have used relative
8288 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00008289
Georg Brandl3ee81df2008-05-17 18:14:43 +00008290- Added case insensitive comparison methods ``PyOS_stricmp(char*,
8291 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00008292
Georg Brandl3ee81df2008-05-17 18:14:43 +00008293- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
8294 macro so it can be used as an expression.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008300- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
8301 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
8302 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
8303 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00008304

Georg Brandl3ee81df2008-05-17 18:14:43 +00008318- Removed the macfs module. It had been deprecated since Python 2.5.
8319 This lead to the deprecation of macostools.touched() as it relied
8320 solely on macfs and was a no-op under OS X.
