Ned Deily18fae3f2013-01-31 01:24:55 -08001550- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
1551 In particular, fix extension module build failures when trying to use
1552 32-bit-only installer Pythons on systems with Xcode 4 (currently
1553 OS X 10.8, 10.7, and optionally 10.6).
1554 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1555 * Since Xcode 4 removes ppc support, extension module builds now
1556 check for ppc compiler support and by default remove ppc and
1557 ppc64 archs when they are not available.
1558 * Extension module builds now revert to using system installed
1559 headers and libs (/usr and /System/Library) if the SDK used
1560 to build the interpreter is not installed or has moved.
1561 * Try to avoid building extension modules with deprecated
1562 and problematic Apple llvm-gcc compiler. If original compiler
1563 is not available, use clang instead by default.

1995 Distutils-based packages with C extension modules may fail because
1996 Apple has removed gcc-4.2, the version used to build python.org
1997 64-bit/32-bit Pythons. If the user does not explicitly override
1998 the default C compiler by setting the CC environment variable,
1999 Distutils will now attempt to compile extension modules with clang
2000 if gcc-4.2 is required but not found. Also as a convenience, if
2001 the user does explicitly set CC, substitute its value as the default
2002 compiler in the Distutils LDSHARED configuration variable for OS X.
2003 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2004 SDK, neither of which are available in Xcode 4. This change does not
2005 attempt to override settings to support their use with Xcode 4.)

Victor Stinner08563d92011-05-30 23:44:13 +02002158
Lars Gustäbel8babfdf2011-09-05 17:04:18 +02002159- Issue #12841: tarfile unnecessarily checked the existence of numerical user
2160 and group ids on extraction. If one of them did not exist the respective id
2161 of the current user (i.e. root) was used for the file and ownership

Ned Deily87e82bb2011-06-28 19:52:59 -07002255- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2256 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2257 interpreter process. This could cause failures in non-Distutils subprocesses
2258 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002259 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002260 deployment target only in the environment of each build subprocess. It is
2261 still possible to globally override the default by setting
2262 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2263 greater or equal to the default value, the value with which the interpreter
2264 was built.
2265

2291
Barry Warsawc5643282011-07-19 17:06:30 -04002292- sys.setcheckinterval() now updates the current ticker count as well as
2293 updating the check interval, so if the user decreases the check interval,
2294 the ticker doesn't have to wind down to zero from the old starting point
2295 before the new interval takes effect. And if the user increases the
2296 interval, it makes sure the new limit takes effect right away rather have an
2297 early task switch before recognizing the new interval.

Raymond Hettinger20397532010-09-12 02:11:45 +00003277- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
3278 This prevents user-created self-referencing ordered dictionaries from
3279 becoming permanently uncollectable GC garbage. The downside is that
3280 removing __del__ means that the internal doubly-linked list has to wait for
3281 GC collection rather than freeing memory immediately when the refcnt drops
3282 to zero.

3743 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3744 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte

Philip Jenveyaebbaeb2010-04-06 23:24:45 +00004126- Issue #7301: Add environment variable $PYTHONWARNINGS.
4127
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00004128- Issue #8329: Don't return the same lists from select.select when no fds are
4129 changed.
4130
Georg Brandlfee0f442010-05-22 21:26:21 +00004131- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00004132 on 64-bit machines. The shift count for either left or right shift is
4133 permitted to be up to sys.maxsize.
4134
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00004135- Ensure that tokenization of identifiers is not affected by locale.

4140
Georg Brandlfee0f442010-05-22 21:26:21 +00004141- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
4142 with a non-empty format string. This is an effort to future-proof user
4143 code. If a derived class does not currently implement __format__ but later
4144 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00004145 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00004146 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00004179- Issue #8257: The Decimal construct now accepts a float instance directly,

Raymond Hettinger34c35b22010-04-03 10:22:00 +00004185- collections.Counter() now supports a subtract() method.
4186
Georg Brandlfee0f442010-05-22 21:26:21 +00004187- The functools module now has a total_ordering() class decorator to simplify

Georg Brandlfee0f442010-05-22 21:26:21 +00004196- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4197 InvalidOperation instead of returning False. (Comparisons involving a quiet
4198 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4199 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00004200
Georg Brandlfee0f442010-05-22 21:26:21 +00004201- Issue #2531: Comparison operations between floats and Decimal instances now
4202 return a result based on the numeric values of the operands; previously they
4203 returned an arbitrary result based on the relative ordering of id(float) and
4204 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00004205
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00004206- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00004207 argument `-` which tells it to read files to compile from stdin. Each line is
4208 read on demand and the named file is compiled immediately. (Original patch by

Florent Xicluna58b65662010-03-30 16:29:03 +00004214- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
4215 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00004216 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/

Georg Brandlfee0f442010-05-22 21:26:21 +00004218- Comparisons using one of <, <=, >, >= between a complex instance and a
4219 Fractions instance now raise TypeError instead of returning True/False. This
4220 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4221 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00004540- Issue #6292: For the moment at least, the test suite runs cleanly if python
R. David Murrayf28fd242010-02-23 00:24:49 +00004541 is run with the -OO flag. Tests requiring docstrings are skipped.
4542
Georg Brandlba83f822010-03-14 09:50:54 +00004543- Issue #7712: test_support gained a new ``temp_cwd`` context manager which is
4544 now also used by regrtest to run all the tests in a temporary directory. The
4545 original CWD is saved in ``test.test_support.SAVEDCWD``. Thanks to Florent
4546 Xicluna who helped with the patch.

4563 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +00004564 library would return a bogus result; on Solaris, it was possible to crash the
4565 interpreter. Patch by Stefan Krah.

Georg Brandlba83f822010-03-14 09:50:54 +00004578- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
4579 and add the additional members returned in an OSVERSIONINFOEX structure. The
4580 new members are service_pack_major, service_pack_minor, suite_mask, and
4581 product_type.

Georg Brandlba83f822010-03-14 09:50:54 +00004583- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
4584 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
4585 returning NULL. The macro now returns a statically allocated empty string
4586 instead.

4596 strings,
4597 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
4598 numeric strings corresponding to subnormal values,
4599 (3) a memory leak for some values large enough to cause overflow, and
4600 (4) a number of flaws that could lead to incorrectly rounded results.

Antoine Pitroud840e512010-02-04 20:20:18 +00004631- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00004632 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00004633 Also, raise ValueError rather than TypeError when an unknown TIPC address
4634 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004638- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00004639 file position when calling `truncate()`. It would previously change the file
4640 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004641 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
4642
Georg Brandlba83f822010-03-14 09:50:54 +00004643- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
4644 class used to represent files stored inside an archive. The new
4645 implementation is significantly faster and can be wrapped in a
4646 ``io.BufferedReader`` object for more speedups. It also solves an issue
4647 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
4648 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +00004658- Issue #7748: Since unicode values are supported for some metadata options in
4659 Distutils, the DistributionMetadata get_* methods will now return an utf-8
4660 encoded string for them. This ensures that the upload and register commands
4661 send the correct values to PyPI without any error.

Benjamin Peterson4f51baf2009-12-05 18:40:02 +00004730What's New in Python 2.7 alpha 2?
4731=================================
4732
Benjamin Petersonaa7e51f2010-01-09 16:34:06 +00004733*Release date: 2010-01-09*

4736-----------------
4737
Georg Brandlba83f822010-03-14 09:50:54 +00004738- The ``__complex__()`` method is now looked up on the class of instances to
4739 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00004740
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00004741- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
4742 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
4743
Mark Dickinson1b34d252010-01-01 17:27:30 +00004744- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004745 DeprecationWarning when passed a float argument where an integer was expected.
4746 These functions and methods now raise TypeError instead. The majority of the
4747 effects of this change are in the extension modules, but some core functions
4748 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4749 and many unicode/str methods.
Mark Dickinson1b34d252010-01-01 17:27:30 +00004750
Benjamin Peterson0f02d392009-12-30 19:34:10 +00004751- Issue #7604: Deleting an unset slotted attribute did not raise an
4752 AttributeError.
4753
Georg Brandlba83f822010-03-14 09:50:54 +00004754- Issue #7534: Fix handling of IEEE specials (infinities, nans, negative zero)

Amaury Forgeot d'Arcc8a2ce72009-12-29 23:06:17 +00004758
Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +00004759- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
4760 used to drop the time part of the result.
4761
Georg Brandlba83f822010-03-14 09:50:54 +00004762- Issue #1811: Improve accuracy and cross-platform consistency for true division
4763 of integers: the result of a/b is now correctly rounded for ints a and b (at
4764 least on IEEE 754 platforms), and in particular does not depend on the
4765 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +00004766
Georg Brandlba83f822010-03-14 09:50:54 +00004767- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
4768 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
4769 in the subclass.
Ezio Melottif84caf42009-12-24 22:25:17 +00004770
Georg Brandlba83f822010-03-14 09:50:54 +00004771- Issue #6834: Replace the implementation for the 'python' and 'pythonw'
Ronald Oussoren92919a62009-12-24 13:30:58 +00004772 executables on OSX.
4773
Georg Brandlba83f822010-03-14 09:50:54 +00004774 These executables now work properly with the arch(1) command: ``arch -ppc
4775 python`` will start a universal binary version of python in PPC mode (unlike
4776 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +00004777
Georg Brandlba83f822010-03-14 09:50:54 +00004778- Issue #1680159: Unicode coercion during an 'in' operation no longer masks the
4779 underlying error when the coercion fails for the left hand operand.
R. David Murray0a0a1a82009-12-14 16:28:26 +00004780
Benjamin Peterson4895af42009-12-13 16:36:53 +00004781- Issue #7491: Metaclass's __cmp__ method was ignored.

Georg Brandlba83f822010-03-14 09:50:54 +00004789- Issue #6963: Added "maxtasksperchild" argument to ``multiprocessing.Pool``,
4790 allowing for a maximum number of tasks within the pool to be completed by the
4791 worker before that worker is terminated, and a new one created to replace it.

Antoine Pitrou80157252010-01-08 19:20:17 +00004797- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
Georg Brandlba83f822010-03-14 09:50:54 +00004798 renaming of `cPickle` to `pickle`. The warning was annoying since there's no
4799 alternative to cPickle if you care about performance. Patch by Florent

Ezio Melotti569e61f2009-12-30 06:14:51 +00004819 Initial patch by Brian Curtin.
4820
Georg Brandlba83f822010-03-14 09:50:54 +00004821- Distutils now correctly identifies the build architecture as "x86_64" when
4822 building on OSX 10.6 without "-arch" flags.
Ronald Oussorenca8e7ec2009-12-24 14:50:35 +00004823

Benjamin Petersonddd392c2009-12-13 19:19:07 +00004834- Issue #7349: Make methods of file objects in the io module accept None as an
4835 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
4836 the same as passing no argument.
4837
Georg Brandlba83f822010-03-14 09:50:54 +00004838- Issue #7348: ``StringIO.StringIO.readline(-1)`` now acts as if it got no
4839 argument like other file objects.

Georg Brandlba83f822010-03-14 09:50:54 +00004860- Issue #5080: The argument parsing functions ``PyArg_ParseTuple()``,
4861 ``PyArg_ParseTupleAndKeywords()``, ``PyArg_VaParse()``,
4862 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept
4863 float arguments for integer format codes (other than 'L'): previously an

Georg Brandlba83f822010-03-14 09:50:54 +00004931- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4932 decimal string that's guaranteed to round back to x under correct rounding
4933 (with round-half-to-even rounding mode). Previously it gave a string based on
4934 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4935 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4936 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004937
Georg Brandlba83f822010-03-14 09:50:54 +00004938- Issue #7117: On almost all platforms: float-to-string and string-to-float
4939 conversions within Python are now correctly rounded. Places these conversions
4940 occur include: str for floats and complex numbers; the float and complex
4941 constructors; old-style and new-style numeric formatting; serialization and
4942 deserialization of floats and complex numbers using marshal, pickle and json;
4943 parsing of float and imaginary literals in Python code; Decimal-to-float
4944 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004945
Georg Brandlba83f822010-03-14 09:50:54 +00004946 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4947 providing correctly-rounded strtod and dtoa C functions. This code is
4948 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4949 the C compiler. There may be a small number of platforms on which correct
4950 operation of this code cannot be guaranteed, so the code is not used: notably,
4951 this applies to platforms where the C double format is not IEEE 754 binary64,
4952 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4953 and Python's configure script is unable to determine how to change the FPU
4954 precision. On these platforms conversions use the platform strtod and dtoa,
4955 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004956
Georg Brandlba83f822010-03-14 09:50:54 +00004957- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4958 uses the correctly-rounded string <-> float conversions described above (when
4959 available), and so produces correctly rounded results that will display nicely
4960 under the float repr. There are two related small changes: (1) round now
4961 accepts any class with an ``__index__()`` method for its second argument (but
4962 no longer accepts floats for the second argument), and (2) an excessively
4963 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer

5191 internal representation of integers, for performance reasons. Base 2**30 is
5192 enabled by default on 64-bit machines. Add --enable-big-digits option to
5193 configure, which overrides the default. Add sys.long_info structseq to
5194 provide information about the internal format.

Georg Brandlba83f822010-03-14 09:50:54 +00005257- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
5258 existing .py counterpart, override the co_filename attributes of all code

5314
Georg Brandlba83f822010-03-14 09:50:54 +00005315- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
5316 file objects with closefd=False. The file descriptor is still kept open but
5317 the file object behaves like a closed file. The ``FileIO`` object also got a

Georg Brandlba83f822010-03-14 09:50:54 +00005341- On windows, ``os.chdir()`` given unicode was not working if
5342 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
5343 this code path is really executed because I cannot move to such directory on
5344 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00005346- Issue #4069: When ``set.remove(element)`` is used with a set element, the
5347 element is temporarily replaced with an equivalent frozenset. But the
5348 eventual KeyError would always report the empty ``frozenset()`` as the missing

5370 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

Walter Dörwald726ba8e2009-05-06 14:32:35 +00005374- Issue #3739: The unicode-internal encoder now reports the number of characters

6556 argument with an __int__ method can be packed, but use of this feature

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006750- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6751 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6752 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6753 ``printf`` function, whereas PyString_FromFormat has an independent
6754 implementation and uses "%zd" on all platforms for size_t values.
6755 This makes a difference on win64, where ``printf`` needs "%Id" to display
6756 64bit values.

Antoine Pitrou0668c622008-08-26 22:42:08 +00006776 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__

Brett Cannon1eaf0742008-09-02 01:25:16 +00006851 warnings.catch_warnings() along with some API cleanup. Expanding the tests
6852 for catch_warnings() also led to an improvement in the raising of a
6853 DeprecationWarning related to warnings.warn_explicit().
6854

6877
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00006878- Issue #2975: When compiling several extension modules with Visual Studio 2008
6879 from the same python interpreter, some environment variables would grow
6880 without limit.
6881
Benjamin Peterson37346b22008-08-23 20:27:43 +00006882- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006919What's New in Python 2.6 beta 3?
6920================================
6921
Barry Warsaw07a4a382008-08-21 01:15:08 +00006922*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006923
6924Core and Builtins
6925-----------------
6926
Guido van Rossumf8402962008-08-20 15:01:50 +00006927- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6928 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6929 extensions do not automatically benefit from the class attribute
6930 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6931 to their tp_flags field if they care. This is a backwards
6932 compatibility feature; in 3.0, all types will use the cache by
6933 default.
6934
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006935- Keyword arguments can now follow starred arguments. (``f(a, *args,
6936 keyword=23)`` is now valid syntax.)
6937
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006938- ctypes function pointers that are COM methods have a boolean True
6939 value again.
6940
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006941- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6942 by denying s# to parse objects that have a releasebuffer procedure,
6943 and introducing s*.
6944
Georg Brandl1e13ea92008-08-11 09:07:59 +00006945- Issue #3537: Fix an assertion failure when an empty but presized dict
6946 object was stored in the freelist.
6947
Mark Dickinsonb6467572008-08-04 21:30:09 +00006948- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6949 ValueError consistently across platforms.
6950
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006951- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6952 (64bit Unix, for example), unichr() would truncate its argument and return
6953 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6954
Neal Norwitze7d8be82008-07-31 17:17:14 +00006955- Apply security patches from Apple.
6956
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006957- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6958 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6959
Antoine Pitrou92f82162008-07-25 22:22:08 +00006960- Issue #1819: function calls with several named parameters are now on
6961 average 35% faster (as measured by pybench).
6962
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006963- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6964 the python debugger steps into a class statement: the free variables (local
6965 variables defined in an outer scope) would be deleted from the outer scope.
6966
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006967- Issue #2620: Overflow checking when allocating or reallocating memory
6968 was not always being done properly in some python types and extension
6969 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6970 all been updated to perform better checks and places in the code that
6971 would previously leak memory on the error path when such an allocation
6972 failed have been fixed.
6973

6975-------
6976

6978
Benjamin Petersone977ad42008-08-20 01:42:01 +00006979- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6980 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6981
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006982- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6983 version reported by these tools does not necessarily follow the python
6984 version numbering scheme, so the module is less strict when parsing it.
6985
Nick Coghlanf70385a2008-08-18 12:42:46 +00006986- Issue #2235: Added Py3k warnings for types which will become unhashable
6987 under the stricter __hash__ inheritance rules in 3.0. Several types
6988 which did not meet the rules for hash invariants and were already
6989 unhashable in 3.0 have now been explicitly flagged as unhashable in
6990 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6991 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6992
Brett Cannon88f801d2008-08-18 00:46:22 +00006993- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

7001
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00007002- Issue #3575: Incremental decoder's decode function now takes bytearray
7003 by using 's*' instead of 't#'.
7004
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00007005- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00007006 fails unicode conversion on 2nd parameter. (windows only)
7007
Georg Brandl222e2082010-08-01 22:27:39 +00007008- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00007009 in a redirect.
7010
Brett Cannonabe423e2008-08-16 21:47:07 +00007011- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00007012 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00007013
Facundo Batistaeb90b782008-08-16 14:44:07 +00007014- Issue #2776: fixed small issue when handling an URL with double slash
7015 after a 302 response in the case of not going through a proxy.
7016
Antoine Pitroub90a8be2008-08-15 21:03:21 +00007017- Issue #2676: in the email package, content-type parsing was hanging on
7018 pathological input because of quadratic or exponential behaviour of a
7019 regular expression.
7020
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00007021- Issue #3476: binary buffered reading through the new "io" library is now
7022 thread-safe.
7023
Brett Cannonbf3157b2008-08-14 05:00:03 +00007024- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
7025 since mimetools itself is deprecated. Because modules are cached, all
7026 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
7027
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00007028- Issue #3134: shutil referenced undefined WindowsError symbol.
7029
Robert Schuppenies14646332008-08-10 11:01:53 +00007030- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
7031 menu entries were not deleted.
7032
Brett Cannon83e81842008-08-09 23:30:55 +00007033- Copied the implementation of reduce() to _functools.reduce() to have a
7034 version that did not raise a DeprecationWarning under -3.
7035
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00007036- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
7037 a MemoryError rather than silently stop the iteration.
7038
Guido van Rossum59ce9012008-08-09 14:55:34 +00007039- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
7040 to _sre.compile() will now be rejected. This should not affect anybody
7041 since the re.compile() function never generates invalid re-bytecode.
7042
Skip Montanaroa032bf42008-08-08 22:52:51 +00007043- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
7044 upon first access it can be automatically initialized from the csv file if
7045 it wasn't initialized during instantiation.
7046
Brett Cannon3aa2a492008-08-06 22:28:09 +00007047- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
7048 the reload() built-in has been removed.
7049
Brett Cannon7e30b672008-08-04 21:52:25 +00007050- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00007051 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00007062 asking for a specific length. This problem only affected files opened
7063 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00007064

7109 regarding lack of coverage of new-style classes have also been
7110 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00007113What's New in Python 2.6 beta 2?
7114================================
7115
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007116*Release date: 17-Jul-2008*
7117
Raymond Hettingere3ae6552008-06-20 04:18:15 +00007118Core and Builtins
7119-----------------
7120
Georg Brandl3e483f62008-07-16 22:57:41 +00007121- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7122 its methods now allow for items objects that can be converted to
7123 an integer using operator.index().
7124
Mark Dickinson64b7e502008-07-16 09:40:03 +00007125- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7126 produced a ValueError instead of giving the correct float.
7127
Eric Smitha5fa5a22008-07-16 00:11:49 +00007128- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
7129 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
7130
Mark Dickinson7103aa42008-07-15 19:08:33 +00007131- Issue #3008: the float type has a new instance method 'float.hex'
7132 and a new class method 'float.fromhex' to convert floating-point
7133 numbers to and from hexadecimal strings, respectively.
7134
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007135- Issue #2235: __hash__ is once again inherited by default. To allow
7136 collections.Hashable to remain meaningful in the presence of the
7137 default hash implementation (object.__hash__), it is now possible
7138 to explicit block inheritance of hash by setting __hash__=None at
7139 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7140 level.
7141
Nick Coghlanb028f502008-07-13 14:52:36 +00007142- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7143 the parent module cannot be found while performing an absolute import.
7144 This means that an incorrectly defined __package__ attribute will
7145 now only prevent relative imports in that module rather than causing
7146 all imports from that module to fail.
7147
Nick Coghlan14ff9942008-07-08 14:21:42 +00007148- Issue #2517: Allow unicode messages in Exceptions again by correctly
7149 bypassing the instance dictionary when looking up __unicode__ on
7150 new-style classes.
7151
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00007152- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
7153 set to a custom object whose write() method happens to install
7154 another file in sys.stdout.
7155
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00007156- Issue #3088: Corrected a race condition in classes derived from
7157 threading.local: the first member set by a thread could be saved in
7158 another thread's dictionary.
7159
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007160- Issue #3004: Minor change to slice.indices(): the start and stop
7161 arguments are now treated identically, making the behaviour easier
7162 to describe and understand. For example, slice(None, -10,
7163 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7164 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7165 10, -1).
7166
Georg Brandl278fc502008-07-19 12:46:12 +00007167- Issue #3219: Calling a function with repeated keyword arguments,
7168 f(a=2, a=23), would not cause a syntax error. This was a regression
7169 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00007170
Georg Brandl278fc502008-07-19 12:46:12 +00007171- Issue #2862: Make int and float freelist management consistent with
7172 other freelists. Changes their CompactFreeList apis into
7173 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00007174
Brett Cannon8bb8fa52008-07-02 01:57:08 +00007175Library
7176-------
7177
Thomas Heller57adf222008-08-14 19:10:48 +00007178- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
7179 api functions without holding the GIL, which could lead to a fatal
7180 error when they failed.
7181
Martin v. Löwisaabf4042008-08-02 07:20:25 +00007182- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.
7183

Jesse Noller13e9d582008-07-16 14:32:36 +00007190- Issue #3125: Remove copy_reg in multiprocessing and replace it with
7191 ForkingPickler.register() to resolve conflict with ctypes.
7192
Vinay Sajip51e65192008-07-18 09:01:10 +00007193- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00007194
Thomas Heller880f5292008-07-15 19:39:38 +00007195- Issue #3313: Fixed a crash when a failed dlopen() call does not set
7196 a valid dlerror() message.
7197
Thomas Heller2bad6572008-07-15 17:19:50 +00007198- Issue #3258: Fixed a crash when a ctypes POINTER type to an
7199 incomplete structure was created.
7200

7202
Raymond Hettingerb01713e2008-07-10 14:34:57 +00007203- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
7204
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007205- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00007206
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007207- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
7208 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007209 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007210 content-length. The problem had been corrected in the 2.4 branch, but never
7211 merged into trunk.
7212
Georg Brandle78fbcc2008-07-05 10:13:36 +00007213- Issue #2663: add filtering capability to shutil.copytree().

7219- Issue #1746: Correct handling of zipfile archive comments (previously
7220 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00007221 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00007222
Vinay Sajip51e65192008-07-18 09:01:10 +00007223- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007224 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00007225
Nick Coghlanc060b0e2008-07-02 13:09:19 +00007226- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
7227 handling is now the same as that of other special attributes like __name__).
7228
Brett Cannon8bb8fa52008-07-02 01:57:08 +00007229- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
7230 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl3ee81df2008-05-17 18:14:43 +00007678- Issue #1631171: Re-implement the 'warnings' module in C (the
7679 original Python code has been kept as backup). This will allow for
7680 using the 'warning's machinery in such places as the parser where
7681 use of pure Python code is not possible. Both the ``showarning()``
7682 and ``formatwarning()`` gain an optional 'line' argument which is
7683 not called by default for backwards-compatibility reasons. Setting
7684 ``warnings.showwarning()`` to an implementation that lacks support
7685 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007748- Issue #2550: The approach used by client/server code for obtaining
7749 ports to listen on in network-oriented tests has been refined in an
7750 effort to facilitate running multiple instances of the entire
7751 regression test suite in parallel without issue.
7752 test_support.bind_port() has been fixed such that it will always
7753 return a unique port -- which wasn't always the case with the
7754 previous implementation, especially if socket options had been set
7755 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7756 new implementation of bind_port() will actually raise an exception
7757 if it is passed an AF_INET/SOCK_STREAM socket with either the
7758 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7759 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7760 the socket it's been passed. This currently only applies to
7761 Windows. This option prevents any other sockets from binding to the
7762 host/port we've bound to, thus removing the possibility of the
7763 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7764 when a second SOCK_STREAM socket binds and accepts to a host/port
7765 that's already been bound by another socket. The optional preferred
7766 port parameter to bind_port() has been removed. Under no
7767 circumstances should tests be hard coding ports!
7768
7769 test_support.find_unused_port() has also been introduced, which will
7770 pass a temporary socket object to bind_port() in order to obtain an
7771 unused port. The temporary socket object is then closed and
7772 deleted, and the port is returned. This method should only be used
7773 for obtaining an unused port in order to pass to an external program
7774 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7775 a parameter to a server-oriented class that doesn't give you direct
7776 access to the underlying socket used.
7777
7778 Finally, test_support.HOST has been introduced, which should be used
7779 for the host argument of any relevant socket calls (i.e. bind and
7780 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007781
7782 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007783 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007784 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7785 test_asynchat and test_socket_ssl.
7786
Georg Brandl3ee81df2008-05-17 18:14:43 +00007787 It is now possible for multiple instances of the regression test
7788 suite to run in parallel without issue.

7944 processor information on Windows XP and later. As a result,
Marc-André Lemburga1867752008-03-20 18:08:00 +00007945 platform.machine() and platform.processor() will report this
7946 information as well.

Eric Smitha73fbe72008-02-23 03:09:44 +00008067- Added the future_builtins module, which contains hex() and oct().
8068 These are the PEP 3127 version of these functions, designed to be
8069 compatible with the hex() and oct() builtins from Python 3.0. They
8070 differ slightly in their output formats from the existing, unchanged
8071 Python 2.6 builtins. The expected usage of the future_builtins
8072 module is:
8073 from future_builtins import hex, oct
8074
Eric Smith7ef40bf2008-02-20 23:34:22 +00008075- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8076 exponents for exponents with absolute value < 100. Follows C99
8077 standard. This is a change on Windows, which would use 3 digits.
8078 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8079 so that any alterations it does to the resulting string will be
8080 available in stringlib/formatter.h (for float.__format__).
8081
Eric Smith5a3c1352008-02-19 13:21:56 +00008082- Implemented PEP 3101, Advanced String Formatting. This adds a new
8083 builtin format(); a format() method for str and unicode; a
8084 __format__() method to object, str, unicode, int, long, float, and
8085 datetime; the class string.Formatter; and the C API
8086 PyObject_Format().
8087
Georg Brandl3ee81df2008-05-17 18:14:43 +00008088- Fixed several potential crashes, all caused by specially crafted
8089 __del__ methods exploiting objects in temporarily inconsistent
8090 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00008091
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008092- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00008093 prevent a possible crash: an Abstract Base Class would try to access
8094 a slot on a registered virtual subclass.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008099- Clear all free lists during a gc.collect() of the highest generation
8100 in order to allow pymalloc to free more arenas. Python may give back
8101 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008102
Georg Brandl3ee81df2008-05-17 18:14:43 +00008103- Issue #2045: Fix an infinite recursion triggered when printing a
8104 subclass of collections.defaultdict, if its default_factory is set
8105 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00008106
Christian Heimesf75dbef2008-02-08 00:11:31 +00008107- Fixed a minor memory leak in dictobject.c. The content of the free
8108 list was not freed on interpreter shutdown.
8109
Georg Brandl21e99f42010-03-07 15:23:59 +00008110- Limit free list of method and built-in function objects to 256

Christian Heimes6075a822008-02-06 12:44:34 +00008112
Georg Brandl3ee81df2008-05-17 18:14:43 +00008113- Patch #1953: Added ``sys._compact_freelists()`` and the C API
8114 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00008115 to compact the internal free lists of pre-allocted ints and floats.
8116
Georg Brandl3ee81df2008-05-17 18:14:43 +00008117- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
8118 calls. Python expected the return type int but the fork familie
8119 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00008120

Georg Brandl3ee81df2008-05-17 18:14:43 +00008133- Patch #1473257: generator objects gain a gi_code attribute. This is
8134 the same object as the func_code attribute of the function that
8135 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008136
Georg Brandl3ee81df2008-05-17 18:14:43 +00008137- Issue #1920: "while 0" statements were completely removed by the
8138 compiler, even in the presence of an "else" clause, which is
8139 supposed to be run when the condition is false. Now the compiler
8140 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008141
Guido van Rossumeead05f2008-01-24 18:21:02 +00008142- A few crashers fixed: weakref_in_del.py (issue #1377858);
8143 loosing_dict_ref.py (issue #1303614, test67.py);
8144 borrowed_ref_[34].py (not in tracker).
8145

8149
Georg Brandl3ee81df2008-05-17 18:14:43 +00008150- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00008151 several extension methods and modules do not work without unicode
8152 support.
8153
Georg Brandl26543b12008-01-21 18:36:51 +00008154- Issue #1882: when compiling code from a string, encoding cookies in the
8155 second line of code were not always recognized correctly.
8156
Georg Brandl14404b62008-01-19 19:27:05 +00008157- Issue #1679: "0x" was taken as a valid integer literal.
8158
Georg Brandl6caad7d2008-01-26 14:19:22 +00008159- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008160 added.
8161
Christian Heimesc94e2b52008-01-14 04:13:37 +00008162- sys.float_info / PyFloat_GetInfo: The floating point information
8163 object was converted from a dict to a specialized structseq object.
8164
Georg Brandl3ee81df2008-05-17 18:14:43 +00008165- Patch #1816: Added sys.flags structseq. It exposes the status of
8166 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008167
Georg Brandl3ee81df2008-05-17 18:14:43 +00008168- Objects/structseq.c: Implemented new structseq representation. The

8179
Georg Brandl3ee81df2008-05-17 18:14:43 +00008180- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
8181 envvar and sys.dont_write_bytecode attribute. All these can be set
8182 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00008183
Georg Brandl3ee81df2008-05-17 18:14:43 +00008184- Improve some exception messages when Windows fails to load an
8185 extension module. Now we get for example '%1 is not a valid Win32
8186 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00008193- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00008194 and INF. float("nan"), float("inf") and float("-inf") now work on
8195 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008197- Compiler now generates simpler and faster code for dictionary
8198 literals. The oparg for BUILD_MAP now indicates an estimated
8199 dictionary size. There is a new opcode, STORE_MAP, for adding
8200 entries to the dictionary.

8230 file can now be directly executed by passing their name to the
8231 interpreter. The directory/zipfile is automatically inserted as the
8232 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008234- Issue #1265: Fix a problem with sys.settrace, if the tracing
8235 function uses a generator expression when at the same time the
8236 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00008237

8243
Georg Brandl21e99f42010-03-07 15:23:59 +00008244- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008245 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8246 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008247
Georg Brandl3ee81df2008-05-17 18:14:43 +00008248- Issue #1686386: Tuple's tp_repr did not take into account the
8249 possibility of having a self-referential tuple, which is possible
8250 from C code. Nor did object's tp_str consider that a type's tp_str
8251 could do something that could lead to an inifinite recursion.
8252 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8253 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008254
Georg Brandl3ee81df2008-05-17 18:14:43 +00008255- Issue #1164: It was possible to trigger deadlock when using the
8256 'print' statement to write to a file since the GIL was not released
8257 as needed. Now PyObject_Print() does the right thing along with
8258 various tp_print implementations of the built-in types and those in
8259 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00008260
Georg Brandl3ee81df2008-05-17 18:14:43 +00008261- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannona0c05512007-09-10 21:38:27 +00008267
Brett Cannon1e534b52007-09-07 04:18:30 +00008268- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008269 PyObject_Call() never calling back out to Python code to trigger
8270 recursion depth updates/checks. Required the creation of a static
8271 RuntimeError instance in case normalizing an exception put the
8272 recursion check value past its limit. Fixes crashers
8273 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00008274

Neal Norwitz0ac60192007-05-27 04:08:54 +00008288- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008289 __*__ attributes. (Some already existed, e.g., __doc__ and
8290 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00008291
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00008292- Add -3 option to the interpreter to warn about features that are
8293 deprecated and will be changed/removed in Python 3.0.
8294
Georg Brandl2134e752007-05-21 20:34:16 +00008295- Patch #1686487: you can now pass any mapping after '**' in function
8296 calls.
8297
Collin Winter62903052007-05-18 23:11:24 +00008298- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00008299 "except E as target:". This is to provide forwards compatibility
8300 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00008307- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00008308 setting a plain string, ie don't expand to single letter identifiers.
8309
Raymond Hettinger13936692007-04-11 18:40:58 +00008310- Request #1191699: Slices can now be pickled.
8311
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008312- Request #1193128: str.translate() now allows a None argument for
8313 translations that only remove characters without re-mapping the
8314 remaining characters.
8315
Georg Brandl5cb76c12007-03-21 09:00:39 +00008316- Patch #1682205: a TypeError while unpacking an iterable is no longer

8320
Guido van Rossum143b5642007-03-23 04:58:42 +00008321- Bug #1683368: The object.__init__() and object.__new__() methods are
8322 now stricter in rejecting excess arguments. The only time when
8323 either allows excess arguments is when it is not overridden and the
8324 other one is. For backwards compatibility, when both are
8325 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008326 warning later). Also, type.__init__() insists on the same signature
8327 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00008328
Georg Brandl3ee81df2008-05-17 18:14:43 +00008329- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8330 object to complex using its __complex__() method before falling back
8331 to the __float__() method. Therefore, the functions in the cmath
8332 module now can operate on objects that define a __complex__()
8333 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008335- Patch #1623563: allow __class__ assignment for classes with
8336 __slots__. The old and the new class are still required to have the
8337 same slot names.

8344 its type.

8350
Georg Brandl7b9c5552007-03-12 14:30:05 +00008351- Bug #1678647: write a newline after printing an exception in any
8352 case, even when converting the value to a string failed.
8353
Georg Brandl871f1bc2007-03-12 13:17:36 +00008354- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008355 its argument, if it exists. If not, it will work like before. This
8356 allows customizing the output of dir() in the presence of a
8357 __getattr__().

8366 parthensized forms. This means complex(repr(x)) now works instead of
8367 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008368
Georg Brandlaa2321b2007-03-07 00:40:28 +00008369- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008370 makes the filenames the warning module prints much more sensible
8371 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00008372

Georg Brandl0fca97a2007-03-05 22:28:08 +00008384- Patch #1674228: when assigning a slice (old-style), check for the
8385 sq_ass_slice instead of the sq_slice slot.
8386
Georg Brandl3ee81df2008-05-17 18:14:43 +00008387- When printing an unraisable error, don't print exceptions. before
8388 the name. This duplicates the behavior whening normally printing
8389 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008921 AttributeError instead of an IOError when the server's response

Georg Brandlf66b6032007-03-14 08:27:52 +00008923

Georg Brandl3ee81df2008-05-17 18:14:43 +00008939- Patch #1530482: add pydoc.render_doc() which returns the

8954
Georg Brandl92a6bae2007-03-13 17:43:32 +00008955- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00008956 are set for invalid interpolation sequences that would lead to
8957 errors on reading back those values.

9000 returned string up to the first NUL character.

9013 TestCase and TestSuite subclasses (not instances) are no longer
9014 accepted in TestSuite.addTest(). This should cause no
9015 incompatibility since it never made sense with ordinary subclasses
9016 -- the failure just occurred later, with a more cumbersome
9017 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00009298 that the SMTP.starttls() caller no longer needs to call ehlo()

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009399- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00009400 time so that opening a database previously created with the DB_DUP
9401 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9402 opens. Specifically: dictionary assignment to a DB object will
9403 replace all values for a given key when the database allows
9404 duplicate values. DB users should use DB.put(k, v) when they want
9405 to store duplicates; not DB[k] = v.

9766 of w# format code incorrectly truncated the length to an int, even
9767 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
9768 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009798- Added case insensitive comparison methods ``PyOS_stricmp(char*,
9799 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
