444
445- As of 2.7.8, the 32-bit-only installer will support OS X 10.5
446 and later systems as is currently done for Python 3.x installers.
447 For 2.7.7 only, we will provide three installers:
448 the legacy deprecated 10.3+ 32-bit-only format;
449 the newer 10.5+ 32-bit-only format;
450 and the unchanged 10.6+ 64-/32-bit format.
451 Although binary installers will no longer be available from
452 python.org as of 2.7.8, it will still be possible to build from
453 source on 10.3.9 and 10.4 systems if necessary.
454 See Mac/BuildScript/README.txt for more information.

Ned Deily18fae3f2013-01-31 01:24:55 -08001831- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
1832 In particular, fix extension module build failures when trying to use
1833 32-bit-only installer Pythons on systems with Xcode 4 (currently
1834 OS X 10.8, 10.7, and optionally 10.6).
1835 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1836 * Since Xcode 4 removes ppc support, extension module builds now
1837 check for ppc compiler support and by default remove ppc and
1838 ppc64 archs when they are not available.
1839 * Extension module builds now revert to using system installed
1840 headers and libs (/usr and /System/Library) if the SDK used
1841 to build the interpreter is not installed or has moved.
1842 * Try to avoid building extension modules with deprecated
1843 and problematic Apple llvm-gcc compiler. If original compiler
1844 is not available, use clang instead by default.

2276 Distutils-based packages with C extension modules may fail because
2277 Apple has removed gcc-4.2, the version used to build python.org
2278 64-bit/32-bit Pythons. If the user does not explicitly override
2279 the default C compiler by setting the CC environment variable,
2280 Distutils will now attempt to compile extension modules with clang
2281 if gcc-4.2 is required but not found. Also as a convenience, if
2282 the user does explicitly set CC, substitute its value as the default
2283 compiler in the Distutils LDSHARED configuration variable for OS X.
2284 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2285 SDK, neither of which are available in Xcode 4. This change does not
2286 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07002536- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2537 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2538 interpreter process. This could cause failures in non-Distutils subprocesses
2539 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002540 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002541 deployment target only in the environment of each build subprocess. It is
2542 still possible to globally override the default by setting
2543 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2544 greater or equal to the default value, the value with which the interpreter
2545 was built.

2575 the ticker doesn't have to wind down to zero from the old starting point
2576 before the new interval takes effect. And if the user increases the
2577 interval, it makes sure the new limit takes effect right away rather have an
2578 early task switch before recognizing the new interval.

Raymond Hettinger20397532010-09-12 02:11:45 +00003558- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
3559 This prevents user-created self-referencing ordered dictionaries from
3560 becoming permanently uncollectable GC garbage. The downside is that
3561 removing __del__ means that the internal doubly-linked list has to wait for
3562 GC collection rather than freeing memory immediately when the refcnt drops
3563 to zero.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00004021- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
4022 start byte and the continuation byte(s) are now considered invalid, instead
4023 of the number of bytes specified by the start byte.
4024 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
4025 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
4026 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

4036 objects. (1) The comparison could incorrectly return True in some cases
4037 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

4406
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00004407- Issue #7301: Add environment variable $PYTHONWARNINGS.
4408
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00004409- Issue #8329: Don't return the same lists from select.select when no fds are
4410 changed.
4411
Georg Brandlfee0f442010-05-22 21:26:21 +00004412- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00004413 on 64-bit machines. The shift count for either left or right shift is
4414 permitted to be up to sys.maxsize.
4415
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00004416- Ensure that tokenization of identifiers is not affected by locale.

4421
Georg Brandlfee0f442010-05-22 21:26:21 +00004422- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
4423 with a non-empty format string. This is an effort to future-proof user
4424 code. If a derived class does not currently implement __format__ but later
4425 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00004426 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00004427 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00004460- Issue #8257: The Decimal construct now accepts a float instance directly,
4461 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00004462

4465
Raymond Hettinger34c35b22010-04-03 10:22:00 +00004466- collections.Counter() now supports a subtract() method.
4467
Georg Brandlfee0f442010-05-22 21:26:21 +00004468- The functools module now has a total_ordering() class decorator to simplify

Georg Brandlfee0f442010-05-22 21:26:21 +00004477- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4478 InvalidOperation instead of returning False. (Comparisons involving a quiet
4479 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4480 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00004481
Georg Brandlfee0f442010-05-22 21:26:21 +00004482- Issue #2531: Comparison operations between floats and Decimal instances now
4483 return a result based on the numeric values of the operands; previously they
4484 returned an arbitrary result based on the relative ordering of id(float) and
4485 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00004486
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00004487- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00004488 argument `-` which tells it to read files to compile from stdin. Each line is
4489 read on demand and the named file is compiled immediately. (Original patch by
4490 Piotr Ożarowski).

Florent Xicluna58b65662010-03-30 16:29:03 +00004495- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
4496 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00004497 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/

Georg Brandlfee0f442010-05-22 21:26:21 +00004499- Comparisons using one of <, <=, >, >= between a complex instance and a
4500 Fractions instance now raise TypeError instead of returning True/False. This
4501 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4502 <=> complex, and complex <=> complex comparisons.

R. David Murrayf28fd242010-02-23 00:24:49 +00004822 is run with the -OO flag. Tests requiring docstrings are skipped.
4823
Georg Brandlba83f822010-03-14 09:50:54 +00004824- Issue #7712: test_support gained a new ``temp_cwd`` context manager which is

4844 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +00004845 library would return a bogus result; on Solaris, it was possible to crash the

Georg Brandlba83f822010-03-14 09:50:54 +00004859- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
4860 and add the additional members returned in an OSVERSIONINFOEX structure. The
4861 new members are service_pack_major, service_pack_minor, suite_mask, and
4862 product_type.

Georg Brandlba83f822010-03-14 09:50:54 +00004864- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
4865 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
4866 returning NULL. The macro now returns a statically allocated empty string
4867 instead.

4877 strings,
4878 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
4879 numeric strings corresponding to subnormal values,
4880 (3) a memory leak for some values large enough to cause overflow, and
4881 (4) a number of flaws that could lead to incorrectly rounded results.

Antoine Pitroud840e512010-02-04 20:20:18 +00004912- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00004913 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00004914 Also, raise ValueError rather than TypeError when an unknown TIPC address
4915 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004919- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00004920 file position when calling `truncate()`. It would previously change the file
4921 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004922 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
4923
Georg Brandlba83f822010-03-14 09:50:54 +00004924- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
4925 class used to represent files stored inside an archive. The new
4926 implementation is significantly faster and can be wrapped in a
4927 ``io.BufferedReader`` object for more speedups. It also solves an issue
4928 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
4929 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +00004939- Issue #7748: Since unicode values are supported for some metadata options in
4940 Distutils, the DistributionMetadata get_* methods will now return an utf-8
4941 encoded string for them. This ensures that the upload and register commands
4942 send the correct values to PyPI without any error.

Benjamin Peterson4f51baf2009-12-05 18:40:02 +00005011What's New in Python 2.7 alpha 2?
5012=================================
5013
Benjamin Petersonaa7e51f2010-01-09 16:34:06 +00005014*Release date: 2010-01-09*

5016Core and Builtins
5017-----------------
5018
Georg Brandlba83f822010-03-14 09:50:54 +00005019- The ``__complex__()`` method is now looked up on the class of instances to
5020 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00005021
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00005022- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
5023 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
5024
Mark Dickinson1b34d252010-01-01 17:27:30 +00005025- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00005026 DeprecationWarning when passed a float argument where an integer was expected.
5027 These functions and methods now raise TypeError instead. The majority of the
5028 effects of this change are in the extension modules, but some core functions
5029 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
5030 and many unicode/str methods.
Mark Dickinson1b34d252010-01-01 17:27:30 +00005031
Benjamin Peterson0f02d392009-12-30 19:34:10 +00005032- Issue #7604: Deleting an unset slotted attribute did not raise an
5033 AttributeError.
5034
Georg Brandlba83f822010-03-14 09:50:54 +00005035- Issue #7534: Fix handling of IEEE specials (infinities, nans, negative zero)

Georg Brandlba83f822010-03-14 09:50:54 +00005038- Issue #7579: The msvcrt module now has docstrings for all its functions.
Amaury Forgeot d'Arcc8a2ce72009-12-29 23:06:17 +00005039
Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +00005040- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
5041 used to drop the time part of the result.
5042
Georg Brandlba83f822010-03-14 09:50:54 +00005043- Issue #1811: Improve accuracy and cross-platform consistency for true division
5044 of integers: the result of a/b is now correctly rounded for ints a and b (at
5045 least on IEEE 754 platforms), and in particular does not depend on the
5046 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +00005047
Georg Brandlba83f822010-03-14 09:50:54 +00005048- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
5049 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
5050 in the subclass.
Ezio Melottif84caf42009-12-24 22:25:17 +00005051
Georg Brandlba83f822010-03-14 09:50:54 +00005052- Issue #6834: Replace the implementation for the 'python' and 'pythonw'
Ronald Oussoren92919a62009-12-24 13:30:58 +00005053 executables on OSX.
5054
Georg Brandlba83f822010-03-14 09:50:54 +00005055 These executables now work properly with the arch(1) command: ``arch -ppc
5056 python`` will start a universal binary version of python in PPC mode (unlike
5057 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +00005058
Georg Brandlba83f822010-03-14 09:50:54 +00005059- Issue #1680159: Unicode coercion during an 'in' operation no longer masks the
5060 underlying error when the coercion fails for the left hand operand.
R. David Murray0a0a1a82009-12-14 16:28:26 +00005061
Benjamin Peterson4895af42009-12-13 16:36:53 +00005062- Issue #7491: Metaclass's __cmp__ method was ignored.

Georg Brandlba83f822010-03-14 09:50:54 +00005070- Issue #6963: Added "maxtasksperchild" argument to ``multiprocessing.Pool``,
5071 allowing for a maximum number of tasks within the pool to be completed by the
5072 worker before that worker is terminated, and a new one created to replace it.
Jesse Noller654ade32010-01-27 03:05:57 +00005073
Georg Brandlba83f822010-03-14 09:50:54 +00005074- Issue #7617: Make sure distutils.unixccompiler.UnixCCompiler recognizes gcc

Antoine Pitrou80157252010-01-08 19:20:17 +00005078- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
Georg Brandlba83f822010-03-14 09:50:54 +00005079 renaming of `cPickle` to `pickle`. The warning was annoying since there's no
5080 alternative to cPickle if you care about performance. Patch by Florent

Georg Brandlba83f822010-03-14 09:50:54 +00005089- Issue #7471: Improve the performance of GzipFile's buffering mechanism, and
5090 make it implement the ``io.BufferedIOBase`` ABC to allow for further speedups
5091 by wrapping it in an ``io.BufferedReader``. Patch by Nir Aides.
Antoine Pitrou673ddf92010-01-03 22:29:56 +00005092

Ezio Melotti569e61f2009-12-30 06:14:51 +00005100 Initial patch by Brian Curtin.
5101
Georg Brandlba83f822010-03-14 09:50:54 +00005102- Distutils now correctly identifies the build architecture as "x86_64" when
5103 building on OSX 10.6 without "-arch" flags.
Ronald Oussorenca8e7ec2009-12-24 14:50:35 +00005104

Benjamin Petersonddd392c2009-12-13 19:19:07 +00005115- Issue #7349: Make methods of file objects in the io module accept None as an
5116 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
5117 the same as passing no argument.
5118
Georg Brandlba83f822010-03-14 09:50:54 +00005119- Issue #7348: ``StringIO.StringIO.readline(-1)`` now acts as if it got no

Georg Brandlba83f822010-03-14 09:50:54 +00005141- Issue #5080: The argument parsing functions ``PyArg_ParseTuple()``,
5142 ``PyArg_ParseTupleAndKeywords()``, ``PyArg_VaParse()``,
5143 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept
5144 float arguments for integer format codes (other than 'L'): previously an

Georg Brandlba83f822010-03-14 09:50:54 +00005212- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
5213 decimal string that's guaranteed to round back to x under correct rounding
5214 (with round-half-to-even rounding mode). Previously it gave a string based on
5215 rounding x to 17 decimal digits. repr(x) for a complex number behaves
5216 similarly. On platforms where the correctly-rounded strtod and dtoa code is
5217 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005218
Georg Brandlba83f822010-03-14 09:50:54 +00005219- Issue #7117: On almost all platforms: float-to-string and string-to-float
5220 conversions within Python are now correctly rounded. Places these conversions
5221 occur include: str for floats and complex numbers; the float and complex
5222 constructors; old-style and new-style numeric formatting; serialization and
5223 deserialization of floats and complex numbers using marshal, pickle and json;
5224 parsing of float and imaginary literals in Python code; Decimal-to-float
5225 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005226
Georg Brandlba83f822010-03-14 09:50:54 +00005227 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
5228 providing correctly-rounded strtod and dtoa C functions. This code is
5229 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5230 the C compiler. There may be a small number of platforms on which correct
5231 operation of this code cannot be guaranteed, so the code is not used: notably,
5232 this applies to platforms where the C double format is not IEEE 754 binary64,
5233 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
5234 and Python's configure script is unable to determine how to change the FPU
5235 precision. On these platforms conversions use the platform strtod and dtoa,
5236 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005237
Georg Brandlba83f822010-03-14 09:50:54 +00005238- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5239 uses the correctly-rounded string <-> float conversions described above (when
5240 available), and so produces correctly rounded results that will display nicely
5241 under the float repr. There are two related small changes: (1) round now
5242 accepts any class with an ``__index__()`` method for its second argument (but
5243 no longer accepts floats for the second argument), and (2) an excessively
5244 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer

5472 internal representation of integers, for performance reasons. Base 2**30 is
5473 enabled by default on 64-bit machines. Add --enable-big-digits option to
5474 configure, which overrides the default. Add sys.long_info structseq to
5475 provide information about the internal format.

Georg Brandlba83f822010-03-14 09:50:54 +00005596- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
5597 file objects with closefd=False. The file descriptor is still kept open but
5598 the file object behaves like a closed file. The ``FileIO`` object also got a

5624 this code path is really executed because I cannot move to such directory on
5625 win2k)

5651 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

6837 argument with an __int__ method can be packed, but use of this feature

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00007031- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
7032 PyString_FromFormat or PyErr_Format to display size_t values. The macro
7033 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
7034 ``printf`` function, whereas PyString_FromFormat has an independent
7035 implementation and uses "%zd" on all platforms for size_t values.

Antoine Pitrou0668c622008-08-26 22:42:08 +00007057 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__

Brett Cannon1eaf0742008-09-02 01:25:16 +00007132 warnings.catch_warnings() along with some API cleanup. Expanding the tests
7133 for catch_warnings() also led to an improvement in the raising of a
7134 DeprecationWarning related to warnings.warn_explicit().
7135

7158
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00007159- Issue #2975: When compiling several extension modules with Visual Studio 2008
7160 from the same python interpreter, some environment variables would grow
7161 without limit.
7162
Benjamin Peterson37346b22008-08-23 20:27:43 +00007163- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007200What's New in Python 2.6 beta 3?
7201================================
7202
Barry Warsaw07a4a382008-08-21 01:15:08 +00007203*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007204
7205Core and Builtins
7206-----------------
7207
Guido van Rossumf8402962008-08-20 15:01:50 +00007208- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
7209 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
7210 extensions do not automatically benefit from the class attribute
7211 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
7212 to their tp_flags field if they care. This is a backwards
7213 compatibility feature; in 3.0, all types will use the cache by
7214 default.
7215
Benjamin Petersonf647dc12008-08-20 01:27:30 +00007216- Keyword arguments can now follow starred arguments. (``f(a, *args,
7217 keyword=23)`` is now valid syntax.)
7218
Thomas Heller0ad5ae02008-08-19 19:25:04 +00007219- ctypes function pointers that are COM methods have a boolean True
7220 value again.
7221
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00007222- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
7223 by denying s# to parse objects that have a releasebuffer procedure,
7224 and introducing s*.
7225
Georg Brandl1e13ea92008-08-11 09:07:59 +00007226- Issue #3537: Fix an assertion failure when an empty but presized dict
7227 object was stored in the freelist.
7228
Mark Dickinsonb6467572008-08-04 21:30:09 +00007229- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
7230 ValueError consistently across platforms.
7231
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00007232- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
7233 (64bit Unix, for example), unichr() would truncate its argument and return
7234 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
7235
Neal Norwitze7d8be82008-07-31 17:17:14 +00007236- Apply security patches from Apple.
7237
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00007238- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
7239 PyErr_ExceptionMatches returns 0 when an exception occurs there.
7240
Antoine Pitrou92f82162008-07-25 22:22:08 +00007241- Issue #1819: function calls with several named parameters are now on
7242 average 35% faster (as measured by pybench).
7243
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00007244- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
7245 the python debugger steps into a class statement: the free variables (local
7246 variables defined in an outer scope) would be deleted from the outer scope.
7247
Gregory P. Smith0470bab2008-07-22 04:46:32 +00007248- Issue #2620: Overflow checking when allocating or reallocating memory
7249 was not always being done properly in some python types and extension
7250 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
7251 all been updated to perform better checks and places in the code that
7252 would previously leak memory on the error path when such an allocation
7253 failed have been fixed.

7256-------
7257
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00007258- Issue #3612: Added some missing basic types in ctypes.wintypes.
7259
Benjamin Petersone977ad42008-08-20 01:42:01 +00007260- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
7261 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
7262
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00007263- Issue #2234: distutils failed for some versions of the cygwin compiler. The
7264 version reported by these tools does not necessarily follow the python
7265 version numbering scheme, so the module is less strict when parsing it.
7266
Nick Coghlanf70385a2008-08-18 12:42:46 +00007267- Issue #2235: Added Py3k warnings for types which will become unhashable
7268 under the stricter __hash__ inheritance rules in 3.0. Several types
7269 which did not meet the rules for hash invariants and were already
7270 unhashable in 3.0 have now been explicitly flagged as unhashable in
7271 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
7272 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
7273
Brett Cannon88f801d2008-08-18 00:46:22 +00007274- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

7282
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00007283- Issue #3575: Incremental decoder's decode function now takes bytearray
7284 by using 's*' instead of 't#'.
7285
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00007286- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00007287 fails unicode conversion on 2nd parameter. (windows only)
7288
Georg Brandl222e2082010-08-01 22:27:39 +00007289- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00007290 in a redirect.
7291

Brett Cannon721b1452008-08-16 22:00:27 +00007293 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00007294
Facundo Batistaeb90b782008-08-16 14:44:07 +00007295- Issue #2776: fixed small issue when handling an URL with double slash
7296 after a 302 response in the case of not going through a proxy.
7297
Antoine Pitroub90a8be2008-08-15 21:03:21 +00007298- Issue #2676: in the email package, content-type parsing was hanging on
7299 pathological input because of quadratic or exponential behaviour of a
7300 regular expression.
7301
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00007302- Issue #3476: binary buffered reading through the new "io" library is now
7303 thread-safe.
7304
Brett Cannonbf3157b2008-08-14 05:00:03 +00007305- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
7306 since mimetools itself is deprecated. Because modules are cached, all
7307 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
7308
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00007309- Issue #3134: shutil referenced undefined WindowsError symbol.
7310
Robert Schuppenies14646332008-08-10 11:01:53 +00007311- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
7312 menu entries were not deleted.
7313
Brett Cannon83e81842008-08-09 23:30:55 +00007314- Copied the implementation of reduce() to _functools.reduce() to have a
7315 version that did not raise a DeprecationWarning under -3.
7316
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00007317- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
7318 a MemoryError rather than silently stop the iteration.
7319
Guido van Rossum59ce9012008-08-09 14:55:34 +00007320- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
7321 to _sre.compile() will now be rejected. This should not affect anybody
7322 since the re.compile() function never generates invalid re-bytecode.
7323
Skip Montanaroa032bf42008-08-08 22:52:51 +00007324- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
7325 upon first access it can be automatically initialized from the csv file if
7326 it wasn't initialized during instantiation.
7327
Brett Cannon3aa2a492008-08-06 22:28:09 +00007328- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
7329 the reload() built-in has been removed.
7330
Brett Cannon7e30b672008-08-04 21:52:25 +00007331- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00007332 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00007343 asking for a specific length. This problem only affected files opened
7344 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00007345

7371 mode 0600 rather than 000 under Unix.
7372

7390 regarding lack of coverage of new-style classes have also been
7391 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00007394What's New in Python 2.6 beta 2?
7395================================
7396
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007397*Release date: 17-Jul-2008*
7398
Raymond Hettingere3ae6552008-06-20 04:18:15 +00007399Core and Builtins
7400-----------------
7401
Georg Brandl3e483f62008-07-16 22:57:41 +00007402- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7403 its methods now allow for items objects that can be converted to
7404 an integer using operator.index().
7405
Mark Dickinson64b7e502008-07-16 09:40:03 +00007406- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7407 produced a ValueError instead of giving the correct float.
7408
Eric Smitha5fa5a22008-07-16 00:11:49 +00007409- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
7410 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
7411
Mark Dickinson7103aa42008-07-15 19:08:33 +00007412- Issue #3008: the float type has a new instance method 'float.hex'
7413 and a new class method 'float.fromhex' to convert floating-point
7414 numbers to and from hexadecimal strings, respectively.
7415
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007416- Issue #2235: __hash__ is once again inherited by default. To allow
7417 collections.Hashable to remain meaningful in the presence of the
7418 default hash implementation (object.__hash__), it is now possible
7419 to explicit block inheritance of hash by setting __hash__=None at
7420 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7421 level.
7422
Nick Coghlanb028f502008-07-13 14:52:36 +00007423- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7424 the parent module cannot be found while performing an absolute import.
7425 This means that an incorrectly defined __package__ attribute will
7426 now only prevent relative imports in that module rather than causing
7427 all imports from that module to fail.
7428
Nick Coghlan14ff9942008-07-08 14:21:42 +00007429- Issue #2517: Allow unicode messages in Exceptions again by correctly
7430 bypassing the instance dictionary when looking up __unicode__ on
7431 new-style classes.
7432
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00007433- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
7434 set to a custom object whose write() method happens to install
7435 another file in sys.stdout.
7436
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00007437- Issue #3088: Corrected a race condition in classes derived from
7438 threading.local: the first member set by a thread could be saved in
7439 another thread's dictionary.
7440
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007441- Issue #3004: Minor change to slice.indices(): the start and stop
7442 arguments are now treated identically, making the behaviour easier
7443 to describe and understand. For example, slice(None, -10,
7444 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7445 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7446 10, -1).
7447
Georg Brandl278fc502008-07-19 12:46:12 +00007448- Issue #3219: Calling a function with repeated keyword arguments,
7449 f(a=2, a=23), would not cause a syntax error. This was a regression
7450 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00007451
Georg Brandl278fc502008-07-19 12:46:12 +00007452- Issue #2862: Make int and float freelist management consistent with
7453 other freelists. Changes their CompactFreeList apis into
7454 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00007455
Brett Cannon8bb8fa52008-07-02 01:57:08 +00007456Library
7457-------
7458
Thomas Heller57adf222008-08-14 19:10:48 +00007459- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
7460 api functions without holding the GIL, which could lead to a fatal
7461 error when they failed.
7462
Martin v. Löwisaabf4042008-08-02 07:20:25 +00007463- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.
7464

Jesse Noller13e9d582008-07-16 14:32:36 +00007471- Issue #3125: Remove copy_reg in multiprocessing and replace it with
7472 ForkingPickler.register() to resolve conflict with ctypes.
7473
Vinay Sajip51e65192008-07-18 09:01:10 +00007474- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00007475
Thomas Heller880f5292008-07-15 19:39:38 +00007476- Issue #3313: Fixed a crash when a failed dlopen() call does not set
7477 a valid dlerror() message.
7478
Thomas Heller2bad6572008-07-15 17:19:50 +00007479- Issue #3258: Fixed a crash when a ctypes POINTER type to an
7480 incomplete structure was created.
7481
Brett Cannon3d0b9f02008-07-13 01:15:07 +00007482- Issue #3339: dummy_thread.acquire() should not return None.
7483
Raymond Hettingerb01713e2008-07-10 14:34:57 +00007484- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
7485
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007486- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00007487
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007488- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
7489 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007490 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007491 content-length. The problem had been corrected in the 2.4 branch, but never
7492 merged into trunk.
7493
Georg Brandle78fbcc2008-07-05 10:13:36 +00007494- Issue #2663: add filtering capability to shutil.copytree().

7500- Issue #1746: Correct handling of zipfile archive comments (previously
7501 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00007502 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00007503
Vinay Sajip51e65192008-07-18 09:01:10 +00007504- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007505 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00007506
Nick Coghlanc060b0e2008-07-02 13:09:19 +00007507- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
7508 handling is now the same as that of other special attributes like __name__).
7509
Brett Cannon8bb8fa52008-07-02 01:57:08 +00007510- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Georg Brandl3ee81df2008-05-17 18:14:43 +00007959- Issue #1631171: Re-implement the 'warnings' module in C (the
7960 original Python code has been kept as backup). This will allow for
7961 using the 'warning's machinery in such places as the parser where
7962 use of pure Python code is not possible. Both the ``showarning()``
7963 and ``formatwarning()`` gain an optional 'line' argument which is
7964 not called by default for backwards-compatibility reasons. Setting
7965 ``warnings.showwarning()`` to an implementation that lacks support
7966 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008029- Issue #2550: The approach used by client/server code for obtaining
8030 ports to listen on in network-oriented tests has been refined in an
8031 effort to facilitate running multiple instances of the entire
8032 regression test suite in parallel without issue.
8033 test_support.bind_port() has been fixed such that it will always
8034 return a unique port -- which wasn't always the case with the
8035 previous implementation, especially if socket options had been set
8036 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
8037 new implementation of bind_port() will actually raise an exception
8038 if it is passed an AF_INET/SOCK_STREAM socket with either the
8039 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
8040 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
8041 the socket it's been passed. This currently only applies to
8042 Windows. This option prevents any other sockets from binding to the
8043 host/port we've bound to, thus removing the possibility of the
8044 'non-deterministic' behaviour, as Microsoft puts it, that occurs
8045 when a second SOCK_STREAM socket binds and accepts to a host/port
8046 that's already been bound by another socket. The optional preferred
8047 port parameter to bind_port() has been removed. Under no
8048 circumstances should tests be hard coding ports!
8049
8050 test_support.find_unused_port() has also been introduced, which will
8051 pass a temporary socket object to bind_port() in order to obtain an
8052 unused port. The temporary socket object is then closed and
8053 deleted, and the port is returned. This method should only be used
8054 for obtaining an unused port in order to pass to an external program
8055 (i.e. the -accept [port] argument to openssl's s_server mode) or as
8056 a parameter to a server-oriented class that doesn't give you direct
8057 access to the underlying socket used.
8058
8059 Finally, test_support.HOST has been introduced, which should be used
8060 for the host argument of any relevant socket calls (i.e. bind and
8061 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00008062
8063 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00008064 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00008065 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
8066 test_asynchat and test_socket_ssl.
8067
Georg Brandl3ee81df2008-05-17 18:14:43 +00008068 It is now possible for multiple instances of the regression test
8069 suite to run in parallel without issue.

8225 processor information on Windows XP and later. As a result,
Marc-André Lemburga1867752008-03-20 18:08:00 +00008226 platform.machine() and platform.processor() will report this
8227 information as well.

Eric Smitha73fbe72008-02-23 03:09:44 +00008348- Added the future_builtins module, which contains hex() and oct().
8349 These are the PEP 3127 version of these functions, designed to be
8350 compatible with the hex() and oct() builtins from Python 3.0. They
8351 differ slightly in their output formats from the existing, unchanged
8352 Python 2.6 builtins. The expected usage of the future_builtins
8353 module is:
8354 from future_builtins import hex, oct
8355
Eric Smith7ef40bf2008-02-20 23:34:22 +00008356- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8357 exponents for exponents with absolute value < 100. Follows C99
8358 standard. This is a change on Windows, which would use 3 digits.
8359 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8360 so that any alterations it does to the resulting string will be
8361 available in stringlib/formatter.h (for float.__format__).
8362
Eric Smith5a3c1352008-02-19 13:21:56 +00008363- Implemented PEP 3101, Advanced String Formatting. This adds a new
8364 builtin format(); a format() method for str and unicode; a
8365 __format__() method to object, str, unicode, int, long, float, and
8366 datetime; the class string.Formatter; and the C API
8367 PyObject_Format().
8368
Georg Brandl3ee81df2008-05-17 18:14:43 +00008369- Fixed several potential crashes, all caused by specially crafted
8370 __del__ methods exploiting objects in temporarily inconsistent
8371 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00008372
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008373- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00008374 prevent a possible crash: an Abstract Base Class would try to access
8375 a slot on a registered virtual subclass.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008380- Clear all free lists during a gc.collect() of the highest generation
8381 in order to allow pymalloc to free more arenas. Python may give back
8382 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008383
Georg Brandl3ee81df2008-05-17 18:14:43 +00008384- Issue #2045: Fix an infinite recursion triggered when printing a
8385 subclass of collections.defaultdict, if its default_factory is set
8386 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00008387
Christian Heimesf75dbef2008-02-08 00:11:31 +00008388- Fixed a minor memory leak in dictobject.c. The content of the free
8389 list was not freed on interpreter shutdown.
8390
Georg Brandl21e99f42010-03-07 15:23:59 +00008391- Limit free list of method and built-in function objects to 256

Christian Heimes6075a822008-02-06 12:44:34 +00008393
Georg Brandl3ee81df2008-05-17 18:14:43 +00008394- Patch #1953: Added ``sys._compact_freelists()`` and the C API
8395 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00008396 to compact the internal free lists of pre-allocted ints and floats.
8397
Georg Brandl3ee81df2008-05-17 18:14:43 +00008398- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
8399 calls. Python expected the return type int but the fork familie
8400 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00008401

Georg Brandl3ee81df2008-05-17 18:14:43 +00008414- Patch #1473257: generator objects gain a gi_code attribute. This is
8415 the same object as the func_code attribute of the function that
8416 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008417
Georg Brandl3ee81df2008-05-17 18:14:43 +00008418- Issue #1920: "while 0" statements were completely removed by the
8419 compiler, even in the presence of an "else" clause, which is
8420 supposed to be run when the condition is false. Now the compiler
8421 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008422
Guido van Rossumeead05f2008-01-24 18:21:02 +00008423- A few crashers fixed: weakref_in_del.py (issue #1377858);
8424 loosing_dict_ref.py (issue #1303614, test67.py);
8425 borrowed_ref_[34].py (not in tracker).
8426

8430
Georg Brandl3ee81df2008-05-17 18:14:43 +00008431- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00008432 several extension methods and modules do not work without unicode
8433 support.
8434
Georg Brandl26543b12008-01-21 18:36:51 +00008435- Issue #1882: when compiling code from a string, encoding cookies in the
8436 second line of code were not always recognized correctly.
8437
Georg Brandl14404b62008-01-19 19:27:05 +00008438- Issue #1679: "0x" was taken as a valid integer literal.
8439
Georg Brandl6caad7d2008-01-26 14:19:22 +00008440- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008441 added.
8442
Christian Heimesc94e2b52008-01-14 04:13:37 +00008443- sys.float_info / PyFloat_GetInfo: The floating point information
8444 object was converted from a dict to a specialized structseq object.
8445
Georg Brandl3ee81df2008-05-17 18:14:43 +00008446- Patch #1816: Added sys.flags structseq. It exposes the status of
8447 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008448
Georg Brandl3ee81df2008-05-17 18:14:43 +00008449- Objects/structseq.c: Implemented new structseq representation. The
8450 patch makes structseqs (e.g. the return value of os.stat) more
8451 readable.

8460
Georg Brandl3ee81df2008-05-17 18:14:43 +00008461- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
8462 envvar and sys.dont_write_bytecode attribute. All these can be set
8463 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00008464
Georg Brandl3ee81df2008-05-17 18:14:43 +00008465- Improve some exception messages when Windows fails to load an
8466 extension module. Now we get for example '%1 is not a valid Win32
8467 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00008474- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00008475 and INF. float("nan"), float("inf") and float("-inf") now work on
8476 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008478- Compiler now generates simpler and faster code for dictionary
8479 literals. The oparg for BUILD_MAP now indicates an estimated
8480 dictionary size. There is a new opcode, STORE_MAP, for adding
8481 entries to the dictionary.

8511 file can now be directly executed by passing their name to the
8512 interpreter. The directory/zipfile is automatically inserted as the
8513 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008515- Issue #1265: Fix a problem with sys.settrace, if the tracing
8516 function uses a generator expression when at the same time the
8517 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00008518

8524
Georg Brandl21e99f42010-03-07 15:23:59 +00008525- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008526 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8527 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008528
Georg Brandl3ee81df2008-05-17 18:14:43 +00008529- Issue #1686386: Tuple's tp_repr did not take into account the
8530 possibility of having a self-referential tuple, which is possible
8531 from C code. Nor did object's tp_str consider that a type's tp_str
8532 could do something that could lead to an inifinite recursion.
8533 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8534 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008535
Georg Brandl3ee81df2008-05-17 18:14:43 +00008536- Issue #1164: It was possible to trigger deadlock when using the
8537 'print' statement to write to a file since the GIL was not released
8538 as needed. Now PyObject_Print() does the right thing along with
8539 various tp_print implementations of the built-in types and those in
8540 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00008541
Georg Brandl3ee81df2008-05-17 18:14:43 +00008542- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannona0c05512007-09-10 21:38:27 +00008548
Brett Cannon1e534b52007-09-07 04:18:30 +00008549- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008550 PyObject_Call() never calling back out to Python code to trigger
8551 recursion depth updates/checks. Required the creation of a static
8552 RuntimeError instance in case normalizing an exception put the
8553 recursion check value past its limit. Fixes crashers
8554 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00008555

Neal Norwitz0ac60192007-05-27 04:08:54 +00008569- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008570 __*__ attributes. (Some already existed, e.g., __doc__ and
8571 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00008572
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00008573- Add -3 option to the interpreter to warn about features that are
8574 deprecated and will be changed/removed in Python 3.0.
8575
Georg Brandl2134e752007-05-21 20:34:16 +00008576- Patch #1686487: you can now pass any mapping after '**' in function
8577 calls.
8578
Collin Winter62903052007-05-18 23:11:24 +00008579- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00008580 "except E as target:". This is to provide forwards compatibility
8581 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00008588- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00008589 setting a plain string, ie don't expand to single letter identifiers.
8590
Raymond Hettinger13936692007-04-11 18:40:58 +00008591- Request #1191699: Slices can now be pickled.
8592
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008593- Request #1193128: str.translate() now allows a None argument for
8594 translations that only remove characters without re-mapping the
8595 remaining characters.
8596
Georg Brandl5cb76c12007-03-21 09:00:39 +00008597- Patch #1682205: a TypeError while unpacking an iterable is no longer

8601
Guido van Rossum143b5642007-03-23 04:58:42 +00008602- Bug #1683368: The object.__init__() and object.__new__() methods are
8603 now stricter in rejecting excess arguments. The only time when
8604 either allows excess arguments is when it is not overridden and the
8605 other one is. For backwards compatibility, when both are
8606 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008607 warning later). Also, type.__init__() insists on the same signature
8608 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00008609
Georg Brandl3ee81df2008-05-17 18:14:43 +00008610- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8611 object to complex using its __complex__() method before falling back
8612 to the __float__() method. Therefore, the functions in the cmath
8613 module now can operate on objects that define a __complex__()
8614 method.

8618 same slot names.

8625 its type.

8631
Georg Brandl7b9c5552007-03-12 14:30:05 +00008632- Bug #1678647: write a newline after printing an exception in any
8633 case, even when converting the value to a string failed.
8634
Georg Brandl871f1bc2007-03-12 13:17:36 +00008635- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008636 its argument, if it exists. If not, it will work like before. This
8637 allows customizing the output of dir() in the presence of a
8638 __getattr__().

8642
Georg Brandl3ee81df2008-05-17 18:14:43 +00008643- Patch #1675981: remove unreachable code from ``type.__new__()``

8647 parthensized forms. This means complex(repr(x)) now works instead of
8648 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008649
Georg Brandlaa2321b2007-03-07 00:40:28 +00008650- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008651 makes the filenames the warning module prints much more sensible
8652 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00008665- Patch #1674228: when assigning a slice (old-style), check for the
8666 sq_ass_slice instead of the sq_slice slot.
8667
Georg Brandl3ee81df2008-05-17 18:14:43 +00008668- When printing an unraisable error, don't print exceptions. before
8669 the name. This duplicates the behavior whening normally printing
8670 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009202 AttributeError instead of an IOError when the server's response

Georg Brandlf66b6032007-03-14 08:27:52 +00009204

Georg Brandl3ee81df2008-05-17 18:14:43 +00009220- Patch #1530482: add pydoc.render_doc() which returns the

9235
Georg Brandl92a6bae2007-03-13 17:43:32 +00009236- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00009237 are set for invalid interpolation sequences that would lead to
9238 errors on reading back those values.

9281 returned string up to the first NUL character.

9294 TestCase and TestSuite subclasses (not instances) are no longer
9295 accepted in TestSuite.addTest(). This should cause no
9296 incompatibility since it never made sense with ordinary subclasses
9297 -- the failure just occurred later, with a more cumbersome
9298 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00009579 that the SMTP.starttls() caller no longer needs to call ehlo()

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009680- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00009681 time so that opening a database previously created with the DB_DUP
9682 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9683 opens. Specifically: dictionary assignment to a DB object will
9684 replace all values for a given key when the database allows
9685 duplicate values. DB users should use DB.put(k, v) when they want
9686 to store duplicates; not DB[k] = v.

10047 of w# format code incorrectly truncated the length to an int, even
10048 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
10049 incorrect results with huge strings.

10073 outside of pystate.c and should not be necessary.
10074
Georg Brandl3ee81df2008-05-17 18:14:43 +000010075- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
10076 absolute imports. In earlier versions they might have used relative
10077 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +000010078
Georg Brandl3ee81df2008-05-17 18:14:43 +000010079- Added case insensitive comparison methods ``PyOS_stricmp(char*,
10080 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
