R David Murray20101872012-08-31 23:15:28 -04001167- Issue #12776,#11839: call argparse type function (specified by add_argument)
1168 only once. Before, the type function was called twice in the case where the
1169 default was specified and the argument was given as well. This was
1170 especially problematic for the FileType type, as a default file would always
1171 be opened, even if a file argument was specified on the command line.

1428 In particular, fix extension module build failures when trying to use
1429 32-bit-only installer Pythons on systems with Xcode 4 (currently
1430 OS X 10.8, 10.7, and optionally 10.6).
1431 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1432 * Since Xcode 4 removes ppc support, extension module builds now
1433 check for ppc compiler support and by default remove ppc and
1434 ppc64 archs when they are not available.
1435 * Extension module builds now revert to using system installed
1436 headers and libs (/usr and /System/Library) if the SDK used
1437 to build the interpreter is not installed or has moved.
1438 * Try to avoid building extension modules with deprecated
1439 and problematic Apple llvm-gcc compiler. If original compiler
1440 is not available, use clang instead by default.

Mark Dickinsondbbed042011-09-19 16:38:08 +01001791- Issue #12973: Fix overflow checks that invoked undefined behaviour in
1792 int.__pow__. These overflow checks were causing int.__pow__ to produce
1793 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +01001794 compiler optimizing the check away. Also fix similar overflow checks
1795 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

Ned Deilyc47a4592012-02-11 20:40:24 +01001865 has left two versions of customize_compiler, the original in

Ned Deily0d0ea482012-02-10 12:59:06 +01001871- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1872 Distutils-based packages with C extension modules may fail because
1873 Apple has removed gcc-4.2, the version used to build python.org
1874 64-bit/32-bit Pythons. If the user does not explicitly override
1875 the default C compiler by setting the CC environment variable,
1876 Distutils will now attempt to compile extension modules with clang
1877 if gcc-4.2 is required but not found. Also as a convenience, if
1878 the user does explicitly set CC, substitute its value as the default
1879 compiler in the Distutils LDSHARED configuration variable for OS X.
1880 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1881 SDK, neither of which are available in Xcode 4. This change does not
1882 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07002132- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2133 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2134 interpreter process. This could cause failures in non-Distutils subprocesses
2135 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002136 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002137 deployment target only in the environment of each build subprocess. It is
2138 still possible to globally override the default by setting
2139 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2140 greater or equal to the default value, the value with which the interpreter
2141 was built.

2170 updating the check interval, so if the user decreases the check interval,
2171 the ticker doesn't have to wind down to zero from the old starting point
2172 before the new interval takes effect. And if the user increases the
2173 interval, it makes sure the new limit takes effect right away rather have an
2174 early task switch before recognizing the new interval.

3155 This prevents user-created self-referencing ordered dictionaries from
3156 becoming permanently uncollectable GC garbage. The downside is that
3157 removing __del__ means that the internal doubly-linked list has to wait for
3158 GC collection rather than freeing memory immediately when the refcnt drops
3159 to zero.

3616
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003617- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3618 start byte and the continuation byte(s) are now considered invalid, instead
3619 of the number of bytes specified by the start byte.
3620 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3621 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3622 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
3623 Previous versions returned a single u'\ufffd'.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00003631- Issue #8748: Fix two issues with comparisons between complex and integer
3632 objects. (1) The comparison could incorrectly return True in some cases
3633 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
3634 (2) The comparison raised an OverflowError for large integers, leading
3635 to unpredictable exceptions when combining integers and complex objects
3636 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +00003638- Issue #5211: Implicit coercion for the complex type is now completely

Georg Brandlfee0f442010-05-22 21:26:21 +00004018- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
4019 with a non-empty format string. This is an effort to future-proof user
4020 code. If a derived class does not currently implement __format__ but later
4021 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00004022 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00004023 Python 3.3 and it will be an error in Python 3.4.

Mark Dickinson8efef5c2010-01-12 22:23:56 +00004471
Georg Brandlba83f822010-03-14 09:50:54 +00004472 (1) a serious 'wrong output' bug that could occur for long (> 40 digit) input
4473 strings,
4474 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
4475 numeric strings corresponding to subnormal values,
4476 (3) a memory leak for some values large enough to cause overflow, and
4477 (4) a number of flaws that could lead to incorrectly rounded results.

Georg Brandlba83f822010-03-14 09:50:54 +00004516 file position when calling `truncate()`. It would previously change the file
4517 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004518 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

4521 class used to represent files stored inside an archive. The new
4522 implementation is significantly faster and can be wrapped in a

4524 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

4537 encoded string for them. This ensures that the upload and register commands
4538 send the correct values to PyPI without any error.

4612Core and Builtins
4613-----------------
4614
Georg Brandlba83f822010-03-14 09:50:54 +00004615- The ``__complex__()`` method is now looked up on the class of instances to
4616 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00004617
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00004618- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
4619 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
4620
Mark Dickinson1b34d252010-01-01 17:27:30 +00004621- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004622 DeprecationWarning when passed a float argument where an integer was expected.
4623 These functions and methods now raise TypeError instead. The majority of the
4624 effects of this change are in the extension modules, but some core functions
4625 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4626 and many unicode/str methods.

4637 used to drop the time part of the result.
4638
Georg Brandlba83f822010-03-14 09:50:54 +00004639- Issue #1811: Improve accuracy and cross-platform consistency for true division
4640 of integers: the result of a/b is now correctly rounded for ints a and b (at
4641 least on IEEE 754 platforms), and in particular does not depend on the
4642 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +00004643
Georg Brandlba83f822010-03-14 09:50:54 +00004644- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the

Ronald Oussoren92919a62009-12-24 13:30:58 +00004649 executables on OSX.
4650
Georg Brandlba83f822010-03-14 09:50:54 +00004651 These executables now work properly with the arch(1) command: ``arch -ppc
4652 python`` will start a universal binary version of python in PPC mode (unlike
4653 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +00004808- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4809 decimal string that's guaranteed to round back to x under correct rounding
4810 (with round-half-to-even rounding mode). Previously it gave a string based on
4811 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4812 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4813 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004814
Georg Brandlba83f822010-03-14 09:50:54 +00004815- Issue #7117: On almost all platforms: float-to-string and string-to-float
4816 conversions within Python are now correctly rounded. Places these conversions
4817 occur include: str for floats and complex numbers; the float and complex
4818 constructors; old-style and new-style numeric formatting; serialization and
4819 deserialization of floats and complex numbers using marshal, pickle and json;
4820 parsing of float and imaginary literals in Python code; Decimal-to-float
4821 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004822
Georg Brandlba83f822010-03-14 09:50:54 +00004823 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4824 providing correctly-rounded strtod and dtoa C functions. This code is
4825 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4826 the C compiler. There may be a small number of platforms on which correct
4827 operation of this code cannot be guaranteed, so the code is not used: notably,
4828 this applies to platforms where the C double format is not IEEE 754 binary64,
4829 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4830 and Python's configure script is unable to determine how to change the FPU
4831 precision. On these platforms conversions use the platform strtod and dtoa,
4832 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00004834- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4835 uses the correctly-rounded string <-> float conversions described above (when
4836 available), and so produces correctly rounded results that will display nicely
4837 under the float repr. There are two related small changes: (1) round now
4838 accepts any class with an ``__index__()`` method for its second argument (but
4839 no longer accepts floats for the second argument), and (2) an excessively
4840 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4841 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00004984 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
4985 (2) parsing of strings representing infinities and nans was locale aware; and
4986 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00004988- Issue #5920: For ``float.__format__()``, change the behavior with the empty
4989 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
4990 but with at least one decimal point and with a default precision
4991 of 12. Previously, the behavior the same but with a default precision of 6.
4992 This more closely matches ``str()``, and reduces surprises when adding
4993 alignment flags to the empty presentation type. This also affects the new
4994 complex.__format__ in the same way.
4995
4996- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

Georg Brandlba83f822010-03-14 09:50:54 +00005177- Issue #4445: Replace ``sizeof(PyStringObject)`` with
5178 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
5179 instances. On a typical machine this saves 3 bytes of memory (on average) per
5180 string allocation.

Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +00005182- Issue #3996: On Windows, the PyOS_CheckStack function would cause the

Georg Brandlba83f822010-03-14 09:50:54 +00005186- Issue #3689: The list reversed iterator now supports __length_hint__ instead

5191
Georg Brandlba83f822010-03-14 09:50:54 +00005192- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
5193 file objects with closefd=False. The file descriptor is still kept open but
5194 the file object behaves like a closed file. The ``FileIO`` object also got a
5195 new readonly attribute ``closefd``.

Georg Brandlba83f822010-03-14 09:50:54 +00005218- On windows, ``os.chdir()`` given unicode was not working if

5220 this code path is really executed because I cannot move to such directory on
5221 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00005223- Issue #4069: When ``set.remove(element)`` is used with a set element, the
5224 element is temporarily replaced with an equivalent frozenset. But the
5225 eventual KeyError would always report the empty ``frozenset()`` as the missing
5226 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00005246- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
5247 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5248 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5249 of using the replace error handler in PyUnicode_DecodeUTF8().
5250
Walter Dörwald726ba8e2009-05-06 14:32:35 +00005251- Issue #3739: The unicode-internal encoder now reports the number of characters

5253
Georg Brandlba83f822010-03-14 09:50:54 +00005254- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
5255 allocator will be automatically disabled when running under Valgrind. This
5256 gives improved memory leak detection when running under Valgrind, while taking
5257 advantage of pymalloc at other times.

6427 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
6428 neither __int__ nor __long__, TypeError used to be raised (with a

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00006625- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
6626
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006627- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6628 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6629 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6630 ``printf`` function, whereas PyString_FromFormat has an independent
6631 implementation and uses "%zd" on all platforms for size_t values.
6632 This makes a difference on win64, where ``printf`` needs "%Id" to display
6633 64bit values.
6634
Benjamin Peterson97179b02008-09-09 20:55:01 +00006635- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

6639 object; previously an int would be returned for small values. the __long__
6640 method is allowed to return either an int or a long, but the behaviour of
6641 float objects should not change to respect backward compatibility.

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00006643- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +00006649 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006650 was correctly parsed but parsing of subsequent arguments failed.
6651
Vinay Sajip35e3b032008-09-01 14:33:59 +00006652- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006653 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6654 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6655 when given a tuple of classes as second argument, were looking up
6656 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6657 type object.
6658
Neal Norwitz18aa3882008-08-24 05:04:52 +00006659- Fix crashes on memory allocation failure found with failmalloc.

Brett Cannon1eaf0742008-09-02 01:25:16 +00006728 warnings.catch_warnings() along with some API cleanup. Expanding the tests
6729 for catch_warnings() also led to an improvement in the raising of a

6802-----------------
6803
Guido van Rossumf8402962008-08-20 15:01:50 +00006804- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6805 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6806 extensions do not automatically benefit from the class attribute
6807 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6808 to their tp_flags field if they care. This is a backwards
6809 compatibility feature; in 3.0, all types will use the cache by
6810 default.
6811
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006812- Keyword arguments can now follow starred arguments. (``f(a, *args,
6813 keyword=23)`` is now valid syntax.)
6814
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006815- ctypes function pointers that are COM methods have a boolean True
6816 value again.

6826 ValueError consistently across platforms.
6827
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006828- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6829 (64bit Unix, for example), unichr() would truncate its argument and return
6830 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6831
Neal Norwitze7d8be82008-07-31 17:17:14 +00006832- Apply security patches from Apple.
6833
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006834- Issue #2542: Now that issubclass() may call arbitrary code, ensure that

6836
Antoine Pitrou92f82162008-07-25 22:22:08 +00006837- Issue #1819: function calls with several named parameters are now on
6838 average 35% faster (as measured by pybench).
6839
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006840- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6841 the python debugger steps into a class statement: the free variables (local
6842 variables defined in an outer scope) would be deleted from the outer scope.
6843
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006844- Issue #2620: Overflow checking when allocating or reallocating memory
6845 was not always being done properly in some python types and extension
6846 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6847 all been updated to perform better checks and places in the code that
6848 would previously leak memory on the error path when such an allocation
6849 failed have been fixed.

6855
Benjamin Petersone977ad42008-08-20 01:42:01 +00006856- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6857 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6858
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006859- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6860 version reported by these tools does not necessarily follow the python
6861 version numbering scheme, so the module is less strict when parsing it.
6862
Nick Coghlanf70385a2008-08-18 12:42:46 +00006863- Issue #2235: Added Py3k warnings for types which will become unhashable
6864 under the stricter __hash__ inheritance rules in 3.0. Several types
6865 which did not meet the rules for hash invariants and were already
6866 unhashable in 3.0 have now been explicitly flagged as unhashable in
6867 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6868 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6869
Brett Cannon88f801d2008-08-18 00:46:22 +00006870- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
6871 imported into the module but exposed as part of the module's API.
6872

Brett Cannonbf3157b2008-08-14 05:00:03 +00006901- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6902 since mimetools itself is deprecated. Because modules are cached, all
6903 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6904
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00006905- Issue #3134: shutil referenced undefined WindowsError symbol.

6914 a MemoryError rather than silently stop the iteration.
6915
Guido van Rossum59ce9012008-08-09 14:55:34 +00006916- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
6917 to _sre.compile() will now be rejected. This should not affect anybody
6918 since the re.compile() function never generates invalid re-bytecode.
6919
Skip Montanaroa032bf42008-08-08 22:52:51 +00006920- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
6921 upon first access it can be automatically initialized from the csv file if
6922 it wasn't initialized during instantiation.
6923
Brett Cannon3aa2a492008-08-06 22:28:09 +00006924- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
6925 the reload() built-in has been removed.
6926
Brett Cannon7e30b672008-08-04 21:52:25 +00006927- Changed code in the following modules/packages to remove warnings raised

Antoine Pitroude781a42008-08-09 12:43:23 +00006939 asking for a specific length. This problem only affected files opened
6940 using the new "io" module, not the built-in open() function.

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00006965- Issue #3394: zipfile.writestr sets external attributes when passed a
6966 file name rather than a ZipInfo instance, so files are extracted with
6967 mode 0600 rather than 000 under Unix.
6968
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00006969- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
6970 argument in python 2.5, this broke code that subclassed Popen to include its

6982 interaction with the tp_hash slot (added in 2.6b2) are now documented
6983
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00006984- Issue #643841: The language reference now provides more detailed
6985 coverage of the lookup process for special methods. The disclaimers
6986 regarding lack of coverage of new-style classes have also been
6987 removed, since the coverage is now fairly reasonable.

6991================================
6992
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006993*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00006995Core and Builtins
6996-----------------
6997
Georg Brandl3e483f62008-07-16 22:57:41 +00006998- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6999 its methods now allow for items objects that can be converted to
7000 an integer using operator.index().
7001
Mark Dickinson64b7e502008-07-16 09:40:03 +00007002- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7003 produced a ValueError instead of giving the correct float.
7004
Eric Smitha5fa5a22008-07-16 00:11:49 +00007005- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
7006 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
7007
Mark Dickinson7103aa42008-07-15 19:08:33 +00007008- Issue #3008: the float type has a new instance method 'float.hex'
7009 and a new class method 'float.fromhex' to convert floating-point
7010 numbers to and from hexadecimal strings, respectively.
7011
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007012- Issue #2235: __hash__ is once again inherited by default. To allow
7013 collections.Hashable to remain meaningful in the presence of the
7014 default hash implementation (object.__hash__), it is now possible
7015 to explicit block inheritance of hash by setting __hash__=None at
7016 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7017 level.
7018
Nick Coghlanb028f502008-07-13 14:52:36 +00007019- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7020 the parent module cannot be found while performing an absolute import.
7021 This means that an incorrectly defined __package__ attribute will
7022 now only prevent relative imports in that module rather than causing
7023 all imports from that module to fail.
7024
Nick Coghlan14ff9942008-07-08 14:21:42 +00007025- Issue #2517: Allow unicode messages in Exceptions again by correctly
7026 bypassing the instance dictionary when looking up __unicode__ on
7027 new-style classes.
7028
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00007029- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
7030 set to a custom object whose write() method happens to install
7031 another file in sys.stdout.
7032
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00007033- Issue #3088: Corrected a race condition in classes derived from
7034 threading.local: the first member set by a thread could be saved in
7035 another thread's dictionary.
7036
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007037- Issue #3004: Minor change to slice.indices(): the start and stop
7038 arguments are now treated identically, making the behaviour easier
7039 to describe and understand. For example, slice(None, -10,
7040 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7041 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7042 10, -1).
7043
Georg Brandl278fc502008-07-19 12:46:12 +00007044- Issue #3219: Calling a function with repeated keyword arguments,
7045 f(a=2, a=23), would not cause a syntax error. This was a regression
7046 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00007047
Georg Brandl278fc502008-07-19 12:46:12 +00007048- Issue #2862: Make int and float freelist management consistent with
7049 other freelists. Changes their CompactFreeList apis into
7050 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00007055- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
7056 api functions without holding the GIL, which could lead to a fatal
7057 error when they failed.
7058
Martin v. Löwisaabf4042008-08-02 07:20:25 +00007059- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

7068 ForkingPickler.register() to resolve conflict with ctypes.
7069
Vinay Sajip51e65192008-07-18 09:01:10 +00007070- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Thomas Heller880f5292008-07-15 19:39:38 +00007072- Issue #3313: Fixed a crash when a failed dlopen() call does not set
7073 a valid dlerror() message.
7074
Thomas Heller2bad6572008-07-15 17:19:50 +00007075- Issue #3258: Fixed a crash when a ctypes POINTER type to an
7076 incomplete structure was created.
7077

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007082- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00007083
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007084- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
7085 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007086 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007087 content-length. The problem had been corrected in the 2.4 branch, but never
7088 merged into trunk.
7089
Georg Brandle78fbcc2008-07-05 10:13:36 +00007090- Issue #2663: add filtering capability to shutil.copytree().

Facundo Batista66c52772008-07-02 16:52:55 +00007102
Nick Coghlanc060b0e2008-07-02 13:09:19 +00007103- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
7104 handling is now the same as that of other special attributes like __name__).
7105
Brett Cannon8bb8fa52008-07-02 01:57:08 +00007106- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

7493 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00007494 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007495
7496 This is controlled by the configure argument ``--with-universal-archs``:
7497
7498 - ``--with-universal-archs=all``: install 4-way universal
7499
7500 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7501
7502 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7503
7504 This option should be used in combination with ``--enable-universalsdk=``.
7505
7506 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 +00007555- Issue #1631171: Re-implement the 'warnings' module in C (the
7556 original Python code has been kept as backup). This will allow for
7557 using the 'warning's machinery in such places as the parser where
7558 use of pure Python code is not possible. Both the ``showarning()``
7559 and ``formatwarning()`` gain an optional 'line' argument which is
7560 not called by default for backwards-compatibility reasons. Setting
7561 ``warnings.showwarning()`` to an implementation that lacks support
7562 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007625- Issue #2550: The approach used by client/server code for obtaining
7626 ports to listen on in network-oriented tests has been refined in an
7627 effort to facilitate running multiple instances of the entire
7628 regression test suite in parallel without issue.
7629 test_support.bind_port() has been fixed such that it will always
7630 return a unique port -- which wasn't always the case with the
7631 previous implementation, especially if socket options had been set
7632 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7633 new implementation of bind_port() will actually raise an exception
7634 if it is passed an AF_INET/SOCK_STREAM socket with either the
7635 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7636 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7637 the socket it's been passed. This currently only applies to
7638 Windows. This option prevents any other sockets from binding to the
7639 host/port we've bound to, thus removing the possibility of the
7640 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7641 when a second SOCK_STREAM socket binds and accepts to a host/port
7642 that's already been bound by another socket. The optional preferred
7643 port parameter to bind_port() has been removed. Under no
7644 circumstances should tests be hard coding ports!
7645
7646 test_support.find_unused_port() has also been introduced, which will
7647 pass a temporary socket object to bind_port() in order to obtain an
7648 unused port. The temporary socket object is then closed and
7649 deleted, and the port is returned. This method should only be used
7650 for obtaining an unused port in order to pass to an external program
7651 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7652 a parameter to a server-oriented class that doesn't give you direct
7653 access to the underlying socket used.
7654
7655 Finally, test_support.HOST has been introduced, which should be used
7656 for the host argument of any relevant socket calls (i.e. bind and
7657 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007658
7659 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007660 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007661 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7662 test_asynchat and test_socket_ssl.
7663
Georg Brandl3ee81df2008-05-17 18:14:43 +00007664 It is now possible for multiple instances of the regression test

7933
Fred Drakea8ee94b2008-03-01 02:45:07 +00007934- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00007935 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00007936
Georg Brandlad61bc82008-02-23 15:11:18 +00007937- Issue #2067: file.__exit__() now calls subclasses' close() method.
7938
7939- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00007940
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007941- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00007942 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00007943
Eric Smitha73fbe72008-02-23 03:09:44 +00007944- Added the future_builtins module, which contains hex() and oct().
7945 These are the PEP 3127 version of these functions, designed to be
7946 compatible with the hex() and oct() builtins from Python 3.0. They
7947 differ slightly in their output formats from the existing, unchanged
7948 Python 2.6 builtins. The expected usage of the future_builtins
7949 module is:
7950 from future_builtins import hex, oct
7951
Eric Smith7ef40bf2008-02-20 23:34:22 +00007952- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7953 exponents for exponents with absolute value < 100. Follows C99
7954 standard. This is a change on Windows, which would use 3 digits.
7955 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7956 so that any alterations it does to the resulting string will be
7957 available in stringlib/formatter.h (for float.__format__).
7958
Eric Smith5a3c1352008-02-19 13:21:56 +00007959- Implemented PEP 3101, Advanced String Formatting. This adds a new
7960 builtin format(); a format() method for str and unicode; a
7961 __format__() method to object, str, unicode, int, long, float, and
7962 datetime; the class string.Formatter; and the C API
7963 PyObject_Format().
7964
Georg Brandl3ee81df2008-05-17 18:14:43 +00007965- Fixed several potential crashes, all caused by specially crafted
7966 __del__ methods exploiting objects in temporarily inconsistent
7967 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00007968
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007969- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00007970 prevent a possible crash: an Abstract Base Class would try to access
7971 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00007972
Georg Brandl3ee81df2008-05-17 18:14:43 +00007973- Fixed repr() and str() of complex numbers with infinity or nan as
7974 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00007975
Georg Brandl3ee81df2008-05-17 18:14:43 +00007976- Clear all free lists during a gc.collect() of the highest generation
7977 in order to allow pymalloc to free more arenas. Python may give back
7978 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007979
Georg Brandl3ee81df2008-05-17 18:14:43 +00007980- Issue #2045: Fix an infinite recursion triggered when printing a
7981 subclass of collections.defaultdict, if its default_factory is set
7982 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007983
Christian Heimesf75dbef2008-02-08 00:11:31 +00007984- Fixed a minor memory leak in dictobject.c. The content of the free
7985 list was not freed on interpreter shutdown.
7986
Georg Brandl21e99f42010-03-07 15:23:59 +00007987- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00007988 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00007989
Georg Brandl3ee81df2008-05-17 18:14:43 +00007990- Patch #1953: Added ``sys._compact_freelists()`` and the C API
7991 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00007992 to compact the internal free lists of pre-allocted ints and floats.
7993
Georg Brandl3ee81df2008-05-17 18:14:43 +00007994- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
7995 calls. Python expected the return type int but the fork familie
7996 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00007997
Georg Brandl3ee81df2008-05-17 18:14:43 +00007998- Issue #1678380: Fix a bug that identifies 0j and -0j when they
7999 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00008000
Georg Brandl3ee81df2008-05-17 18:14:43 +00008001- Issue #2025: Add tuple.count() and tuple.index() methods to comply
8002 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00008003
Georg Brandl3ee81df2008-05-17 18:14:43 +00008004- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
8005 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00008006
Georg Brandl3ee81df2008-05-17 18:14:43 +00008007- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
8008 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00008009
Georg Brandl3ee81df2008-05-17 18:14:43 +00008010- Patch #1473257: generator objects gain a gi_code attribute. This is
8011 the same object as the func_code attribute of the function that
8012 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008013
Georg Brandl3ee81df2008-05-17 18:14:43 +00008014- Issue #1920: "while 0" statements were completely removed by the
8015 compiler, even in the presence of an "else" clause, which is
8016 supposed to be run when the condition is false. Now the compiler
8017 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008018
Guido van Rossumeead05f2008-01-24 18:21:02 +00008019- A few crashers fixed: weakref_in_del.py (issue #1377858);
8020 loosing_dict_ref.py (issue #1303614, test67.py);
8021 borrowed_ref_[34].py (not in tracker).
8022
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00008023- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00008024 suppressed while an extension is loaded by calling SetErrorMode in
8025 dynload_win.c. The error is still reported properly.
8026
Georg Brandl3ee81df2008-05-17 18:14:43 +00008027- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00008028 several extension methods and modules do not work without unicode
8029 support.
8030
Georg Brandl26543b12008-01-21 18:36:51 +00008031- Issue #1882: when compiling code from a string, encoding cookies in the
8032 second line of code were not always recognized correctly.
8033
Georg Brandl14404b62008-01-19 19:27:05 +00008034- Issue #1679: "0x" was taken as a valid integer literal.
8035
Georg Brandl6caad7d2008-01-26 14:19:22 +00008036- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008037 added.
8038
Christian Heimesc94e2b52008-01-14 04:13:37 +00008039- sys.float_info / PyFloat_GetInfo: The floating point information
8040 object was converted from a dict to a specialized structseq object.
8041
Georg Brandl3ee81df2008-05-17 18:14:43 +00008042- Patch #1816: Added sys.flags structseq. It exposes the status of
8043 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008044
Georg Brandl3ee81df2008-05-17 18:14:43 +00008045- Objects/structseq.c: Implemented new structseq representation. The
8046 patch makes structseqs (e.g. the return value of os.stat) more
8047 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00008048
Georg Brandl3ee81df2008-05-17 18:14:43 +00008049- Patch #1700288: added a type attribute cache that caches method
8050 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00008051
Neal Norwitz3fc15b82008-01-10 05:42:58 +00008052- Bug #1776: __import__() no longer accepts filenames on any platform.
8053 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00008054
Georg Brandlaed6c662008-01-07 17:25:53 +00008055- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
8056
Georg Brandl3ee81df2008-05-17 18:14:43 +00008057- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
8058 envvar and sys.dont_write_bytecode attribute. All these can be set
8059 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00008060
Georg Brandl3ee81df2008-05-17 18:14:43 +00008061- Improve some exception messages when Windows fails to load an
8062 extension module. Now we get for example '%1 is not a valid Win32
8063 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00008064
Georg Brandl3ee81df2008-05-17 18:14:43 +00008065- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008067- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
8068 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00008069
Christian Heimes0a8143f2007-12-18 23:22:54 +00008070- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00008071 and INF. float("nan"), float("inf") and float("-inf") now work on
8072 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00008073
Georg Brandl3ee81df2008-05-17 18:14:43 +00008074- Compiler now generates simpler and faster code for dictionary
8075 literals. The oparg for BUILD_MAP now indicates an estimated
8076 dictionary size. There is a new opcode, STORE_MAP, for adding
8077 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00008078
Georg Brandl3ee81df2008-05-17 18:14:43 +00008079- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008084- Issue #1538: Avoid copying string in split/rsplit if the split char
8085 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00008086
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00008087- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00008088 SystemError.
8089
Nick Coghlanef01d822007-12-03 12:55:17 +00008090- PEP 366: Allow explicit relative imports when executing modules
8091 inside packages with the -m switch via a new module level
8092 __package__ attribute.
8093
Georg Brandl3ee81df2008-05-17 18:14:43 +00008094- Issue #1402: Fix a crash on exit, when another thread is still
8095 running, and if the deallocation of its frames somehow calls the
8096 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00008097

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00008101 attribute of an empty cell object.
8102
Georg Brandl3ee81df2008-05-17 18:14:43 +00008103- Issue #1460: The utf-7 incremental decoder did not accept truncated
8104 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00008105
Georg Brandl3ee81df2008-05-17 18:14:43 +00008106- Patch #1739468: Directories and zipfiles containing a __main__.py
8107 file can now be directly executed by passing their name to the
8108 interpreter. The directory/zipfile is automatically inserted as the
8109 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00008110
Georg Brandl3ee81df2008-05-17 18:14:43 +00008111- Issue #1265: Fix a problem with sys.settrace, if the tracing
8112 function uses a generator expression when at the same time the
8113 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00008114
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00008115- sets and frozensets now have an isdisjoint() method.
8116
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00008117- optimize the performance of builtin.sum().
8118
Neal Norwitz44f326e2007-10-05 05:29:17 +00008119- Fix warnings found by the new version of the Coverity checker.
8120
Georg Brandl21e99f42010-03-07 15:23:59 +00008121- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008122 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8123 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008124
Georg Brandl3ee81df2008-05-17 18:14:43 +00008125- Issue #1686386: Tuple's tp_repr did not take into account the
8126 possibility of having a self-referential tuple, which is possible
8127 from C code. Nor did object's tp_str consider that a type's tp_str
8128 could do something that could lead to an inifinite recursion.
8129 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8130 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008131
Georg Brandl3ee81df2008-05-17 18:14:43 +00008132- Issue #1164: It was possible to trigger deadlock when using the
8133 'print' statement to write to a file since the GIL was not released
8134 as needed. Now PyObject_Print() does the right thing along with
8135 various tp_print implementations of the built-in types and those in
8136 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00008137
Georg Brandl3ee81df2008-05-17 18:14:43 +00008138- Issue #1147: Exceptions were directly allowing string exceptions in
8139 their throw() method even though string exceptions no longer
8140 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00008141
Georg Brandl3ee81df2008-05-17 18:14:43 +00008142- Issue #1096: Prevent a segfault from getting the repr of a very
8143 deeply nested list by using the recursion counter.

Brett Cannon1e534b52007-09-07 04:18:30 +00008145- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008146 PyObject_Call() never calling back out to Python code to trigger
8147 recursion depth updates/checks. Required the creation of a static
8148 RuntimeError instance in case normalizing an exception put the
8149 recursion check value past its limit. Fixes crashers
8150 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00008151
Georg Brandl3ee81df2008-05-17 18:14:43 +00008152- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00008165- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008166 __*__ attributes. (Some already existed, e.g., __doc__ and
8167 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00008168
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00008169- Add -3 option to the interpreter to warn about features that are
8170 deprecated and will be changed/removed in Python 3.0.
8171
Georg Brandl2134e752007-05-21 20:34:16 +00008172- Patch #1686487: you can now pass any mapping after '**' in function
8173 calls.
8174
Collin Winter62903052007-05-18 23:11:24 +00008175- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00008176 "except E as target:". This is to provide forwards compatibility
8177 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00008178
Brett Cannon229cee22007-05-05 01:34:02 +00008179- Deprecate BaseException.message as per PEP 352.
8180
Georg Brandl3ee81df2008-05-17 18:14:43 +00008181- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00008182 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00008183
Vinay Sajip8549ce32007-05-06 17:53:37 +00008184- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00008185 setting a plain string, ie don't expand to single letter identifiers.
8186
Raymond Hettinger13936692007-04-11 18:40:58 +00008187- Request #1191699: Slices can now be pickled.
8188
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008189- Request #1193128: str.translate() now allows a None argument for
8190 translations that only remove characters without re-mapping the
8191 remaining characters.
8192
Georg Brandl5cb76c12007-03-21 09:00:39 +00008193- Patch #1682205: a TypeError while unpacking an iterable is no longer

8197
Guido van Rossum143b5642007-03-23 04:58:42 +00008198- Bug #1683368: The object.__init__() and object.__new__() methods are
8199 now stricter in rejecting excess arguments. The only time when
8200 either allows excess arguments is when it is not overridden and the
8201 other one is. For backwards compatibility, when both are
8202 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008203 warning later). Also, type.__init__() insists on the same signature
8204 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00008205
Georg Brandl3ee81df2008-05-17 18:14:43 +00008206- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8207 object to complex using its __complex__() method before falling back
8208 to the __float__() method. Therefore, the functions in the cmath
8209 module now can operate on objects that define a __complex__()
8210 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00008228- Bug #1678647: write a newline after printing an exception in any
8229 case, even when converting the value to a string failed.
8230
Georg Brandl871f1bc2007-03-12 13:17:36 +00008231- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008232 its argument, if it exists. If not, it will work like before. This
8233 allows customizing the output of dir() in the presence of a
8234 __getattr__().

Collin Winter276887b2007-03-12 16:11:39 +00008236- Patch #922167: Python no longer segfaults when faced with infinitely
8237 self-recursive reload() calls (as reported by bug #742342).

8243 parthensized forms. This means complex(repr(x)) now works instead of
8244 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008245
Georg Brandlaa2321b2007-03-07 00:40:28 +00008246- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008247 makes the filenames the warning module prints much more sensible
8248 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00008249

Georg Brandl0fca97a2007-03-05 22:28:08 +00008261- Patch #1674228: when assigning a slice (old-style), check for the
8262 sq_ass_slice instead of the sq_slice slot.
8263
Georg Brandl3ee81df2008-05-17 18:14:43 +00008264- When printing an unraisable error, don't print exceptions. before
8265 the name. This duplicates the behavior whening normally printing
8266 exceptions.

8275 created a weakref on itself during a __del__ call for new-style
8276 classes (classic classes still have the bug).

Georg Brandl2c1375c2006-10-12 11:27:59 +00008316- Bug #1545497: when given an explicit base, int() did ignore NULs
8317 embedded in the string to convert.
8318
Georg Brandl846f73a2006-10-08 07:11:54 +00008319- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl4e933132006-09-06 20:05:58 +00008349- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008367 generator expressions (x for x, in ... ) works again. Fixing this
8368 problem required changing the .pyc magic number. This means that
8369 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009169- Issue #829951: In the smtplib module, SMTP.starttls() now complies
9170 with RFC 3207 and forgets any knowledge obtained from the server not
9171 obtained from the TLS negotiation itself. Patch contributed by Bill
9172 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00009173
Georg Brandl3ee81df2008-05-17 18:14:43 +00009174- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00009175 that the SMTP.starttls() caller no longer needs to call ehlo()
9176 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00009177 does not claim to support starttls. Adds the
9178 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

9259 complex, tuple, list, dict, set, and frozenset. Formerly, it would
9260 silently miscode subclasses of those types. Now, it raises a
9261 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00009262

Georg Brandl3ee81df2008-05-17 18:14:43 +00009277 time so that opening a database previously created with the DB_DUP
9278 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9279 opens. Specifically: dictionary assignment to a DB object will
9280 replace all values for a given key when the database allows
9281 duplicate values. DB users should use DB.put(k, v) when they want
9282 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009283

9289 characters with ASCII value less than 32. Also, it correctly quotes
9290 dots only if they occur on a single line, as opposed to the previous
9291 behavior of quoting dots if they are the second character of any
9292 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00009293

Georg Brandl3ee81df2008-05-17 18:14:43 +00009642- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
9643 of w# format code incorrectly truncated the length to an int, even
9644 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
9645 incorrect results with huge strings.

9655 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00009656
9657- Patch #1733960: Allow T_LONGLONG to accept ints.

9665- Fix some leftovers from the conversion from int to Py_ssize_t
9666 (relevant to strings and sequences of more than 2**31 items).
9667
9668- Make _PyGILState_NoteThreadState() static, it was not used anywhere
9669 outside of pystate.c and should not be necessary.

9673 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00009674
Georg Brandl3ee81df2008-05-17 18:14:43 +00009675- Added case insensitive comparison methods ``PyOS_stricmp(char*,
9676 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00009677
Georg Brandl3ee81df2008-05-17 18:14:43 +00009678- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00009684- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
9685 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION

Georg Brandl3ee81df2008-05-17 18:14:43 +00009701- Removed the macfs module. It had been deprecated since Python 2.5.
9702 This lead to the deprecation of macostools.touched() as it relied
9703 solely on macfs and was a no-op under OS X.
