39 longer include a "manifest" to prevent them failing at import time in some

Mark Dickinsondbbed042011-09-19 16:38:08 +010051- Issue #12973: Fix overflow checks that invoked undefined behaviour in
52 int.__pow__. These overflow checks were causing int.__pow__ to produce
53 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +010054 compiler optimizing the check away. Also fix similar overflow checks
55 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
56 bugs caused test failures with recent versions of Clang.

68 cleared by the garbage collector. This fixes a segfault when an instance
69 and its type get caught in a reference cycle, and the instance's
70 deallocator calls one of the methods on the type (e.g. when subclassing
71 IOBase). Diagnosis and patch by Davide Rizzo.
72
Victor Stinnerba8b3a22011-07-08 02:07:45 +020073- Issue #12501: Adjust callable() warning: callable() is only not supported in

75

81 raw_input() interrupted by CTRL+c.
82
Łukasz Langa7a153902011-10-18 17:16:00 +020083- Issue #10860: httplib now correctly handles an empty port after port
84 delimiter in URLs.

Ned Deily87e82bb2011-06-28 19:52:59 -0700320- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
321 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
322 interpreter process. This could cause failures in non-Distutils subprocesses
323 and was unreliable since tests or user programs could modify the interpreter
324 environment after Distutils set it. Instead, have Distutils set the the
325 deployment target only in the environment of each build subprocess. It is
326 still possible to globally override the default by setting
327 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
328 greater or equal to the default value, the value with which the interpreter
329 was built.

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

Raymond Hettinger20397532010-09-12 02:11:45 +00001276- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
1277 This prevents user-created self-referencing ordered dictionaries from
1278 becoming permanently uncollectable GC garbage. The downside is that
1279 removing __del__ means that the internal doubly-linked list has to wait for
1280 GC collection rather than freeing memory immediately when the refcnt drops
1281 to zero.

1743 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and

Philip Jenveyaebbaeb2010-04-06 23:24:45 +00002126- Issue #7301: Add environment variable $PYTHONWARNINGS.
2127
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00002128- Issue #8329: Don't return the same lists from select.select when no fds are
2129 changed.
2130
Georg Brandlfee0f442010-05-22 21:26:21 +00002131- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00002132 on 64-bit machines. The shift count for either left or right shift is
2133 permitted to be up to sys.maxsize.

Georg Brandlfee0f442010-05-22 21:26:21 +00002141- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2142 with a non-empty format string. This is an effort to future-proof user
2143 code. If a derived class does not currently implement __format__ but later
2144 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002145 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002146 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00002179- Issue #8257: The Decimal construct now accepts a float instance directly,
2180 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00002181

Raymond Hettinger34c35b22010-04-03 10:22:00 +00002185- collections.Counter() now supports a subtract() method.
2186
Georg Brandlfee0f442010-05-22 21:26:21 +00002187- The functools module now has a total_ordering() class decorator to simplify

Georg Brandlfee0f442010-05-22 21:26:21 +00002196- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
2197 InvalidOperation instead of returning False. (Comparisons involving a quiet
2198 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2199 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00002200
Georg Brandlfee0f442010-05-22 21:26:21 +00002201- Issue #2531: Comparison operations between floats and Decimal instances now
2202 return a result based on the numeric values of the operands; previously they
2203 returned an arbitrary result based on the relative ordering of id(float) and
2204 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00002205
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002206- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00002207 argument `-` which tells it to read files to compile from stdin. Each line is
2208 read on demand and the named file is compiled immediately. (Original patch by

Florent Xicluna58b65662010-03-30 16:29:03 +00002214- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
2215 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00002216 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/

Georg Brandlfee0f442010-05-22 21:26:21 +00002218- Comparisons using one of <, <=, >, >= between a complex instance and a
2219 Fractions instance now raise TypeError instead of returning True/False. This
2220 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2221 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00002540- Issue #6292: For the moment at least, the test suite runs cleanly if python
R. David Murrayf28fd242010-02-23 00:24:49 +00002541 is run with the -OO flag. Tests requiring docstrings are skipped.
2542
Georg Brandlba83f822010-03-14 09:50:54 +00002543- Issue #7712: test_support gained a new ``temp_cwd`` context manager which is
2544 now also used by regrtest to run all the tests in a temporary directory. The
2545 original CWD is saved in ``test.test_support.SAVEDCWD``. Thanks to Florent
2546 Xicluna who helped with the patch.

2563 and read operations on write-only file objects. On Windows, the system C
Georg Brandlba83f822010-03-14 09:50:54 +00002564 library would return a bogus result; on Solaris, it was possible to crash the
2565 interpreter. Patch by Stefan Krah.

Georg Brandlba83f822010-03-14 09:50:54 +00002578- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
2579 and add the additional members returned in an OSVERSIONINFOEX structure. The
2580 new members are service_pack_major, service_pack_minor, suite_mask, and
2581 product_type.

Georg Brandlba83f822010-03-14 09:50:54 +00002583- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
2584 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
2585 returning NULL. The macro now returns a statically allocated empty string
2586 instead.
Antoine Pitroue80a6a42010-01-17 12:26:20 +00002587

2596 strings,
2597 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
2598 numeric strings corresponding to subnormal values,
2599 (3) a memory leak for some values large enough to cause overflow, and
2600 (4) a number of flaws that could lead to incorrectly rounded results.

Antoine Pitroud840e512010-02-04 20:20:18 +00002631- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00002632 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00002633 Also, raise ValueError rather than TypeError when an unknown TIPC address
2634 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002638- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00002639 file position when calling `truncate()`. It would previously change the file
2640 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002641 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
2642
Georg Brandlba83f822010-03-14 09:50:54 +00002643- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
2644 class used to represent files stored inside an archive. The new
2645 implementation is significantly faster and can be wrapped in a
2646 ``io.BufferedReader`` object for more speedups. It also solves an issue
2647 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
2648 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +00002658- Issue #7748: Since unicode values are supported for some metadata options in
2659 Distutils, the DistributionMetadata get_* methods will now return an utf-8
2660 encoded string for them. This ensures that the upload and register commands
2661 send the correct values to PyPI without any error.

Benjamin Peterson4f51baf2009-12-05 18:40:02 +00002730What's New in Python 2.7 alpha 2?
2731=================================
2732
Benjamin Petersonaa7e51f2010-01-09 16:34:06 +00002733*Release date: 2010-01-09*
Benjamin Peterson4f51baf2009-12-05 18:40:02 +00002734
2735Core and Builtins
2736-----------------
2737
Georg Brandlba83f822010-03-14 09:50:54 +00002738- The ``__complex__()`` method is now looked up on the class of instances to
2739 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00002740
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00002741- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
2742 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
2743
Mark Dickinson1b34d252010-01-01 17:27:30 +00002744- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00002745 DeprecationWarning when passed a float argument where an integer was expected.
2746 These functions and methods now raise TypeError instead. The majority of the
2747 effects of this change are in the extension modules, but some core functions
2748 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2749 and many unicode/str methods.
Mark Dickinson1b34d252010-01-01 17:27:30 +00002750
Benjamin Peterson0f02d392009-12-30 19:34:10 +00002751- Issue #7604: Deleting an unset slotted attribute did not raise an
2752 AttributeError.
2753

Amaury Forgeot d'Arcc8a2ce72009-12-29 23:06:17 +00002758
Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +00002759- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
2760 used to drop the time part of the result.
2761
Georg Brandlba83f822010-03-14 09:50:54 +00002762- Issue #1811: Improve accuracy and cross-platform consistency for true division
2763 of integers: the result of a/b is now correctly rounded for ints a and b (at
2764 least on IEEE 754 platforms), and in particular does not depend on the
2765 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +00002766
Georg Brandlba83f822010-03-14 09:50:54 +00002767- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
2768 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
2769 in the subclass.
Ezio Melottif84caf42009-12-24 22:25:17 +00002770

Ronald Oussoren92919a62009-12-24 13:30:58 +00002772 executables on OSX.
2773
Georg Brandlba83f822010-03-14 09:50:54 +00002774 These executables now work properly with the arch(1) command: ``arch -ppc
2775 python`` will start a universal binary version of python in PPC mode (unlike
2776 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +00002777
Georg Brandlba83f822010-03-14 09:50:54 +00002778- Issue #1680159: Unicode coercion during an 'in' operation no longer masks the
2779 underlying error when the coercion fails for the left hand operand.
R. David Murray0a0a1a82009-12-14 16:28:26 +00002780
Benjamin Peterson4895af42009-12-13 16:36:53 +00002781- Issue #7491: Metaclass's __cmp__ method was ignored.

Georg Brandlba83f822010-03-14 09:50:54 +00002790- Issue #6963: Added "maxtasksperchild" argument to ``multiprocessing.Pool``,
2791 allowing for a maximum number of tasks within the pool to be completed by the
2792 worker before that worker is terminated, and a new one created to replace it.

Antoine Pitrou80157252010-01-08 19:20:17 +00002798- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
Georg Brandlba83f822010-03-14 09:50:54 +00002799 renaming of `cPickle` to `pickle`. The warning was annoying since there's no
2800 alternative to cPickle if you care about performance. Patch by Florent

Georg Brandlba83f822010-03-14 09:50:54 +00002819- Issue #5511: ``zipfile.ZipFile`` can now be used as a context manager.
Ezio Melotti569e61f2009-12-30 06:14:51 +00002820 Initial patch by Brian Curtin.
2821
Georg Brandlba83f822010-03-14 09:50:54 +00002822- Distutils now correctly identifies the build architecture as "x86_64" when

Benjamin Petersonddd392c2009-12-13 19:19:07 +00002835- Issue #7349: Make methods of file objects in the io module accept None as an
2836 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
2837 the same as passing no argument.
2838
Georg Brandlba83f822010-03-14 09:50:54 +00002839- Issue #7348: ``StringIO.StringIO.readline(-1)`` now acts as if it got no
2840 argument like other file objects.
Benjamin Petersonc4771d22009-12-13 17:31:31 +00002841

Mark Dickinsona36507c2010-01-30 10:08:33 +00002860
Georg Brandlba83f822010-03-14 09:50:54 +00002861- Issue #5080: The argument parsing functions ``PyArg_ParseTuple()``,
2862 ``PyArg_ParseTupleAndKeywords()``, ``PyArg_VaParse()``,
2863 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept
2864 float arguments for integer format codes (other than 'L'): previously an
2865 attempt to pass a float resulted in a DeprecationWarning; now it gives a
2866 TypeError. For the 'L' format code (which previously had no warning) there is
2867 now a DeprecationWarning.

2916 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00002917

Georg Brandlba83f822010-03-14 09:50:54 +00002932- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2933 decimal string that's guaranteed to round back to x under correct rounding
2934 (with round-half-to-even rounding mode). Previously it gave a string based on
2935 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2936 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2937 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002938
Georg Brandlba83f822010-03-14 09:50:54 +00002939- Issue #7117: On almost all platforms: float-to-string and string-to-float
2940 conversions within Python are now correctly rounded. Places these conversions
2941 occur include: str for floats and complex numbers; the float and complex
2942 constructors; old-style and new-style numeric formatting; serialization and
2943 deserialization of floats and complex numbers using marshal, pickle and json;
2944 parsing of float and imaginary literals in Python code; Decimal-to-float
2945 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002946
Georg Brandlba83f822010-03-14 09:50:54 +00002947 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2948 providing correctly-rounded strtod and dtoa C functions. This code is
2949 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2950 the C compiler. There may be a small number of platforms on which correct
2951 operation of this code cannot be guaranteed, so the code is not used: notably,
2952 this applies to platforms where the C double format is not IEEE 754 binary64,
2953 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2954 and Python's configure script is unable to determine how to change the FPU
2955 precision. On these platforms conversions use the platform strtod and dtoa,
2956 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002957
Georg Brandlba83f822010-03-14 09:50:54 +00002958- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2959 uses the correctly-rounded string <-> float conversions described above (when
2960 available), and so produces correctly rounded results that will display nicely
2961 under the float repr. There are two related small changes: (1) round now
2962 accepts any class with an ``__index__()`` method for its second argument (but
2963 no longer accepts floats for the second argument), and (2) an excessively
2964 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer

3192 internal representation of integers, for performance reasons. Base 2**30 is
3193 enabled by default on 64-bit machines. Add --enable-big-digits option to
3194 configure, which overrides the default. Add sys.long_info structseq to
3195 provide information about the internal format.

Georg Brandlba83f822010-03-14 09:50:54 +00003258- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
3259 existing .py counterpart, override the co_filename attributes of all code

3315
Georg Brandlba83f822010-03-14 09:50:54 +00003316- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
3317 file objects with closefd=False. The file descriptor is still kept open but
3318 the file object behaves like a closed file. The ``FileIO`` object also got a

Georg Brandlba83f822010-03-14 09:50:54 +00003342- On windows, ``os.chdir()`` given unicode was not working if
3343 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
3344 this code path is really executed because I cannot move to such directory on
3345 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00003347- Issue #4069: When ``set.remove(element)`` is used with a set element, the
3348 element is temporarily replaced with an equivalent frozenset. But the
3349 eventual KeyError would always report the empty ``frozenset()`` as the missing

3371 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
3372 step. This avoids problems with counting UTF-8 bytes that ignores the effect

Walter Dörwald726ba8e2009-05-06 14:32:35 +00003375- Issue #3739: The unicode-internal encoder now reports the number of characters

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004748- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4749 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4750 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4751 ``printf`` function, whereas PyString_FromFormat has an independent
4752 implementation and uses "%zd" on all platforms for size_t values.

Brett Cannon1eaf0742008-09-02 01:25:16 +00004849 warnings.catch_warnings() along with some API cleanup. Expanding the tests
4850 for catch_warnings() also led to an improvement in the raising of a
4851 DeprecationWarning related to warnings.warn_explicit().
4852
Benjamin Peterson973e6c22008-09-01 23:12:58 +00004853- The deprecation warnings for the old camelCase threading API were removed.

4875
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00004876- Issue #2975: When compiling several extension modules with Visual Studio 2008
4877 from the same python interpreter, some environment variables would grow
4878 without limit.
4879
Benjamin Peterson37346b22008-08-23 20:27:43 +00004880- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
4881 exploitation of poor argument checking.
4882
Gerhard Häringef2276b2008-09-12 13:54:06 +00004883- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".
4884
Gerhard Häring6e1afcf2008-09-12 18:58:57 +00004885- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
4886 remaining ones have "pysqlite_" prefix.
4887

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004917What's New in Python 2.6 beta 3?
4918================================
4919
Barry Warsaw07a4a382008-08-21 01:15:08 +00004920*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004921
4922Core and Builtins
4923-----------------
4924
Guido van Rossumf8402962008-08-20 15:01:50 +00004925- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4926 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4927 extensions do not automatically benefit from the class attribute
4928 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4929 to their tp_flags field if they care. This is a backwards
4930 compatibility feature; in 3.0, all types will use the cache by
4931 default.
4932
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004933- Keyword arguments can now follow starred arguments. (``f(a, *args,
4934 keyword=23)`` is now valid syntax.)
4935
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004936- ctypes function pointers that are COM methods have a boolean True
4937 value again.
4938
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004939- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4940 by denying s# to parse objects that have a releasebuffer procedure,
4941 and introducing s*.
4942
Georg Brandl1e13ea92008-08-11 09:07:59 +00004943- Issue #3537: Fix an assertion failure when an empty but presized dict
4944 object was stored in the freelist.
4945
Mark Dickinsonb6467572008-08-04 21:30:09 +00004946- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4947 ValueError consistently across platforms.
4948
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004949- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4950 (64bit Unix, for example), unichr() would truncate its argument and return
4951 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4952
Neal Norwitze7d8be82008-07-31 17:17:14 +00004953- Apply security patches from Apple.
4954
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004955- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4956 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4957
Antoine Pitrou92f82162008-07-25 22:22:08 +00004958- Issue #1819: function calls with several named parameters are now on
4959 average 35% faster (as measured by pybench).
4960
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004961- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4962 the python debugger steps into a class statement: the free variables (local
4963 variables defined in an outer scope) would be deleted from the outer scope.
4964
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004965- Issue #2620: Overflow checking when allocating or reallocating memory
4966 was not always being done properly in some python types and extension
4967 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4968 all been updated to perform better checks and places in the code that
4969 would previously leak memory on the error path when such an allocation
4970 failed have been fixed.
4971
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004972Library
4973-------
4974
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00004975- Issue #3612: Added some missing basic types in ctypes.wintypes.
4976
Benjamin Petersone977ad42008-08-20 01:42:01 +00004977- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4978 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4979
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004980- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4981 version reported by these tools does not necessarily follow the python
4982 version numbering scheme, so the module is less strict when parsing it.
4983
Nick Coghlanf70385a2008-08-18 12:42:46 +00004984- Issue #2235: Added Py3k warnings for types which will become unhashable
4985 under the stricter __hash__ inheritance rules in 3.0. Several types
4986 which did not meet the rules for hash invariants and were already
4987 unhashable in 3.0 have now been explicitly flagged as unhashable in
4988 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4989 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4990
Brett Cannon88f801d2008-08-18 00:46:22 +00004991- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4992 imported into the module but exposed as part of the module's API.
4993
Brett Cannon7b96f072008-08-18 00:41:11 +00004994- Remove an unneeded import of abc.ABCMeta from 'inspect'.
4995
Brett Cannon46225e72008-08-18 00:36:52 +00004996- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00004998- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
4999
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005000- Issue #3575: Incremental decoder's decode function now takes bytearray
5001 by using 's*' instead of 't#'.
5002
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00005003- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00005004 fails unicode conversion on 2nd parameter. (windows only)
5005
Georg Brandl222e2082010-08-01 22:27:39 +00005006- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00005007 in a redirect.
5008
Brett Cannonabe423e2008-08-16 21:47:07 +00005009- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00005010 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00005011
Facundo Batistaeb90b782008-08-16 14:44:07 +00005012- Issue #2776: fixed small issue when handling an URL with double slash
5013 after a 302 response in the case of not going through a proxy.
5014
Antoine Pitroub90a8be2008-08-15 21:03:21 +00005015- Issue #2676: in the email package, content-type parsing was hanging on
5016 pathological input because of quadratic or exponential behaviour of a
5017 regular expression.
5018
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00005019- Issue #3476: binary buffered reading through the new "io" library is now
5020 thread-safe.
5021
Brett Cannonbf3157b2008-08-14 05:00:03 +00005022- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5023 since mimetools itself is deprecated. Because modules are cached, all
5024 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5025
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00005026- Issue #3134: shutil referenced undefined WindowsError symbol.
5027
Robert Schuppenies14646332008-08-10 11:01:53 +00005028- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
5029 menu entries were not deleted.
5030
Brett Cannon83e81842008-08-09 23:30:55 +00005031- Copied the implementation of reduce() to _functools.reduce() to have a
5032 version that did not raise a DeprecationWarning under -3.
5033
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00005034- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
5035 a MemoryError rather than silently stop the iteration.
5036
Guido van Rossum59ce9012008-08-09 14:55:34 +00005037- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5038 to _sre.compile() will now be rejected. This should not affect anybody
5039 since the re.compile() function never generates invalid re-bytecode.
5040
Skip Montanaroa032bf42008-08-08 22:52:51 +00005041- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5042 upon first access it can be automatically initialized from the csv file if
5043 it wasn't initialized during instantiation.
5044
Brett Cannon3aa2a492008-08-06 22:28:09 +00005045- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5046 the reload() built-in has been removed.
5047
Brett Cannon7e30b672008-08-04 21:52:25 +00005048- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00005049 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00005060 asking for a specific length. This problem only affected files opened
5061 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00005062

5107 regarding lack of coverage of new-style classes have also been
5108 removed, since the coverage is now fairly reasonable.

5117-----------------
5118
Georg Brandl3e483f62008-07-16 22:57:41 +00005119- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5120 its methods now allow for items objects that can be converted to
5121 an integer using operator.index().
5122
Mark Dickinson64b7e502008-07-16 09:40:03 +00005123- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5124 produced a ValueError instead of giving the correct float.
5125
Eric Smitha5fa5a22008-07-16 00:11:49 +00005126- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5127 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5128
Mark Dickinson7103aa42008-07-15 19:08:33 +00005129- Issue #3008: the float type has a new instance method 'float.hex'
5130 and a new class method 'float.fromhex' to convert floating-point
5131 numbers to and from hexadecimal strings, respectively.
5132
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005133- Issue #2235: __hash__ is once again inherited by default. To allow
5134 collections.Hashable to remain meaningful in the presence of the
5135 default hash implementation (object.__hash__), it is now possible
5136 to explicit block inheritance of hash by setting __hash__=None at
5137 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5138 level.
5139
Nick Coghlanb028f502008-07-13 14:52:36 +00005140- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5141 the parent module cannot be found while performing an absolute import.
5142 This means that an incorrectly defined __package__ attribute will
5143 now only prevent relative imports in that module rather than causing
5144 all imports from that module to fail.
5145
Nick Coghlan14ff9942008-07-08 14:21:42 +00005146- Issue #2517: Allow unicode messages in Exceptions again by correctly
5147 bypassing the instance dictionary when looking up __unicode__ on
5148 new-style classes.
5149
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00005150- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
5151 set to a custom object whose write() method happens to install
5152 another file in sys.stdout.
5153
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00005154- Issue #3088: Corrected a race condition in classes derived from
5155 threading.local: the first member set by a thread could be saved in
5156 another thread's dictionary.
5157
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005158- Issue #3004: Minor change to slice.indices(): the start and stop
5159 arguments are now treated identically, making the behaviour easier
5160 to describe and understand. For example, slice(None, -10,
5161 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5162 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5163 10, -1).
5164
Georg Brandl278fc502008-07-19 12:46:12 +00005165- Issue #3219: Calling a function with repeated keyword arguments,
5166 f(a=2, a=23), would not cause a syntax error. This was a regression
5167 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00005168
Georg Brandl278fc502008-07-19 12:46:12 +00005169- Issue #2862: Make int and float freelist management consistent with
5170 other freelists. Changes their CompactFreeList apis into
5171 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00005172

5174-------
5175
Thomas Heller57adf222008-08-14 19:10:48 +00005176- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
5177 api functions without holding the GIL, which could lead to a fatal
5178 error when they failed.
5179
Martin v. Löwisaabf4042008-08-02 07:20:25 +00005180- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.
5181

5187
Jesse Noller13e9d582008-07-16 14:32:36 +00005188- Issue #3125: Remove copy_reg in multiprocessing and replace it with
5189 ForkingPickler.register() to resolve conflict with ctypes.
5190
Vinay Sajip51e65192008-07-18 09:01:10 +00005191- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00005192
Thomas Heller880f5292008-07-15 19:39:38 +00005193- Issue #3313: Fixed a crash when a failed dlopen() call does not set
5194 a valid dlerror() message.
5195
Thomas Heller2bad6572008-07-15 17:19:50 +00005196- Issue #3258: Fixed a crash when a ctypes POINTER type to an
5197 incomplete structure was created.
5198
Brett Cannon3d0b9f02008-07-13 01:15:07 +00005199- Issue #3339: dummy_thread.acquire() should not return None.
5200
Raymond Hettingerb01713e2008-07-10 14:34:57 +00005201- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
5202
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005203- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00005204
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005205- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
5206 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005207 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005208 content-length. The problem had been corrected in the 2.4 branch, but never
5209 merged into trunk.
5210
Georg Brandle78fbcc2008-07-05 10:13:36 +00005211- Issue #2663: add filtering capability to shutil.copytree().

5214
5215- Issue #1526: Allow more than 64k files to be added to Zip64 file.
5216
5217- Issue #1746: Correct handling of zipfile archive comments (previously
5218 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00005219 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00005220
Vinay Sajip51e65192008-07-18 09:01:10 +00005221- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005222 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00005223
Nick Coghlanc060b0e2008-07-02 13:09:19 +00005224- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
5225 handling is now the same as that of other special attributes like __name__).
5226
Brett Cannon8bb8fa52008-07-02 01:57:08 +00005227- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
5228 removal in Python 3.0 in favor of urllib2.urlopen().

5239 default https port (443).
5240
Gregory P. Smithdb3409c2008-07-17 03:13:05 +00005241- Issue #874900: after an os.fork() call the threading module state is cleaned

Georg Brandl3ee81df2008-05-17 18:14:43 +00005679- Issue #1631171: Re-implement the 'warnings' module in C (the
5680 original Python code has been kept as backup). This will allow for
5681 using the 'warning's machinery in such places as the parser where
5682 use of pure Python code is not possible. Both the ``showarning()``
5683 and ``formatwarning()`` gain an optional 'line' argument which is
5684 not called by default for backwards-compatibility reasons. Setting
5685 ``warnings.showwarning()`` to an implementation that lacks support
5686 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005749- Issue #2550: The approach used by client/server code for obtaining
5750 ports to listen on in network-oriented tests has been refined in an
5751 effort to facilitate running multiple instances of the entire
5752 regression test suite in parallel without issue.
5753 test_support.bind_port() has been fixed such that it will always
5754 return a unique port -- which wasn't always the case with the
5755 previous implementation, especially if socket options had been set
5756 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5757 new implementation of bind_port() will actually raise an exception
5758 if it is passed an AF_INET/SOCK_STREAM socket with either the
5759 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5760 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5761 the socket it's been passed. This currently only applies to
5762 Windows. This option prevents any other sockets from binding to the
5763 host/port we've bound to, thus removing the possibility of the
5764 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5765 when a second SOCK_STREAM socket binds and accepts to a host/port
5766 that's already been bound by another socket. The optional preferred
5767 port parameter to bind_port() has been removed. Under no
5768 circumstances should tests be hard coding ports!
5769
5770 test_support.find_unused_port() has also been introduced, which will
5771 pass a temporary socket object to bind_port() in order to obtain an
5772 unused port. The temporary socket object is then closed and
5773 deleted, and the port is returned. This method should only be used
5774 for obtaining an unused port in order to pass to an external program
5775 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5776 a parameter to a server-oriented class that doesn't give you direct
5777 access to the underlying socket used.
5778
5779 Finally, test_support.HOST has been introduced, which should be used
5780 for the host argument of any relevant socket calls (i.e. bind and
5781 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005782
5783 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005784 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005785 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5786 test_asynchat and test_socket_ssl.
5787
Georg Brandl3ee81df2008-05-17 18:14:43 +00005788 It is now possible for multiple instances of the regression test
5789 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00006068- Added the future_builtins module, which contains hex() and oct().
6069 These are the PEP 3127 version of these functions, designed to be
6070 compatible with the hex() and oct() builtins from Python 3.0. They
6071 differ slightly in their output formats from the existing, unchanged
6072 Python 2.6 builtins. The expected usage of the future_builtins
6073 module is:
6074 from future_builtins import hex, oct
6075
Eric Smith7ef40bf2008-02-20 23:34:22 +00006076- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6077 exponents for exponents with absolute value < 100. Follows C99
6078 standard. This is a change on Windows, which would use 3 digits.
6079 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6080 so that any alterations it does to the resulting string will be
6081 available in stringlib/formatter.h (for float.__format__).
6082
Eric Smith5a3c1352008-02-19 13:21:56 +00006083- Implemented PEP 3101, Advanced String Formatting. This adds a new
6084 builtin format(); a format() method for str and unicode; a
6085 __format__() method to object, str, unicode, int, long, float, and
6086 datetime; the class string.Formatter; and the C API
6087 PyObject_Format().
6088
Georg Brandl3ee81df2008-05-17 18:14:43 +00006089- Fixed several potential crashes, all caused by specially crafted
6090 __del__ methods exploiting objects in temporarily inconsistent
6091 state.

6102 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006103
Georg Brandl3ee81df2008-05-17 18:14:43 +00006104- Issue #2045: Fix an infinite recursion triggered when printing a
6105 subclass of collections.defaultdict, if its default_factory is set
6106 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006107
Christian Heimesf75dbef2008-02-08 00:11:31 +00006108- Fixed a minor memory leak in dictobject.c. The content of the free
6109 list was not freed on interpreter shutdown.
6110
Georg Brandl21e99f42010-03-07 15:23:59 +00006111- Limit free list of method and built-in function objects to 256

6115 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006116 to compact the internal free lists of pre-allocted ints and floats.
6117
Georg Brandl3ee81df2008-05-17 18:14:43 +00006118- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6119 calls. Python expected the return type int but the fork familie
6120 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006134- Patch #1473257: generator objects gain a gi_code attribute. This is
6135 the same object as the func_code attribute of the function that
6136 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006137
Georg Brandl3ee81df2008-05-17 18:14:43 +00006138- Issue #1920: "while 0" statements were completely removed by the
6139 compiler, even in the presence of an "else" clause, which is
6140 supposed to be run when the condition is false. Now the compiler
6141 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006142
Guido van Rossumeead05f2008-01-24 18:21:02 +00006143- A few crashers fixed: weakref_in_del.py (issue #1377858);

6150
Georg Brandl3ee81df2008-05-17 18:14:43 +00006151- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006152 several extension methods and modules do not work without unicode
6153 support.
6154

6157
Georg Brandl14404b62008-01-19 19:27:05 +00006158- Issue #1679: "0x" was taken as a valid integer literal.
6159
Georg Brandl6caad7d2008-01-26 14:19:22 +00006160- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006161 added.
6162
Christian Heimesc94e2b52008-01-14 04:13:37 +00006163- sys.float_info / PyFloat_GetInfo: The floating point information

6165
Georg Brandl3ee81df2008-05-17 18:14:43 +00006166- Patch #1816: Added sys.flags structseq. It exposes the status of
6167 most command line arguments and PYTHON* environment variables.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006185- Improve some exception messages when Windows fails to load an
6186 extension module. Now we get for example '%1 is not a valid Win32
6187 application' instead of 'error code 193'.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006195 and INF. float("nan"), float("inf") and float("-inf") now work on
6196 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006198- Compiler now generates simpler and faster code for dictionary
6199 literals. The oparg for BUILD_MAP now indicates an estimated
6200 dictionary size. There is a new opcode, STORE_MAP, for adding
6201 entries to the dictionary.

6231 file can now be directly executed by passing their name to the
6232 interpreter. The directory/zipfile is automatically inserted as the
6233 first entry in sys.path.

6244
Georg Brandl21e99f42010-03-07 15:23:59 +00006245- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006246 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6247 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006248
Georg Brandl3ee81df2008-05-17 18:14:43 +00006249- Issue #1686386: Tuple's tp_repr did not take into account the
6250 possibility of having a self-referential tuple, which is possible
6251 from C code. Nor did object's tp_str consider that a type's tp_str
6252 could do something that could lead to an inifinite recursion.
6253 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6254 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006255
Georg Brandl3ee81df2008-05-17 18:14:43 +00006256- Issue #1164: It was possible to trigger deadlock when using the
6257 'print' statement to write to a file since the GIL was not released
6258 as needed. Now PyObject_Print() does the right thing along with
6259 various tp_print implementations of the built-in types and those in
6260 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006261
Georg Brandl3ee81df2008-05-17 18:14:43 +00006262- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannon1e534b52007-09-07 04:18:30 +00006269- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006270 PyObject_Call() never calling back out to Python code to trigger
6271 recursion depth updates/checks. Required the creation of a static
6272 RuntimeError instance in case normalizing an exception put the
6273 recursion check value past its limit. Fixes crashers
6274 infinite_rec_(1|2|4|5).py.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006290 __*__ attributes. (Some already existed, e.g., __doc__ and
6291 __name__.)

6297 calls.
6298
Collin Winter62903052007-05-18 23:11:24 +00006299- except clauses may now be spelled either "except E, target:" or

6301 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00006308- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006309 setting a plain string, ie don't expand to single letter identifiers.
6310
Raymond Hettinger13936692007-04-11 18:40:58 +00006311- Request #1191699: Slices can now be pickled.
6312
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006313- Request #1193128: str.translate() now allows a None argument for

6315 remaining characters.
6316
Georg Brandl5cb76c12007-03-21 09:00:39 +00006317- Patch #1682205: a TypeError while unpacking an iterable is no longer

6321
Guido van Rossum143b5642007-03-23 04:58:42 +00006322- Bug #1683368: The object.__init__() and object.__new__() methods are
6323 now stricter in rejecting excess arguments. The only time when
6324 either allows excess arguments is when it is not overridden and the
6325 other one is. For backwards compatibility, when both are
6326 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006327 warning later). Also, type.__init__() insists on the same signature
6328 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00006330- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6331 object to complex using its __complex__() method before falling back
6332 to the __float__() method. Therefore, the functions in the cmath
6333 module now can operate on objects that define a __complex__()
6334 method.

6351
Georg Brandl7b9c5552007-03-12 14:30:05 +00006352- Bug #1678647: write a newline after printing an exception in any
6353 case, even when converting the value to a string failed.
6354
Georg Brandl871f1bc2007-03-12 13:17:36 +00006355- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006356 its argument, if it exists. If not, it will work like before. This
6357 allows customizing the output of dir() in the presence of a
6358 __getattr__().

6367 parthensized forms. This means complex(repr(x)) now works instead of
6368 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006369
Georg Brandlaa2321b2007-03-07 00:40:28 +00006370- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006371 makes the filenames the warning module prints much more sensible
6372 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00006385- Patch #1674228: when assigning a slice (old-style), check for the
6386 sq_ass_slice instead of the sq_slice slot.
6387
Georg Brandl3ee81df2008-05-17 18:14:43 +00006388- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00006958 are set for invalid interpolation sequences that would lead to

7015 TestCase and TestSuite subclasses (not instances) are no longer
7016 accepted in TestSuite.addTest(). This should cause no

7018 -- the failure just occurred later, with a more cumbersome
7019 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00007306 that the SMTP.starttls() caller no longer needs to call ehlo()

Georg Brandl3ee81df2008-05-17 18:14:43 +00007308 does not claim to support starttls. Adds the

Georg Brandl3ee81df2008-05-17 18:14:43 +00007408 time so that opening a database previously created with the DB_DUP
7409 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7410 opens. Specifically: dictionary assignment to a DB object will
7411 replace all values for a given key when the database allows
7412 duplicate values. DB users should use DB.put(k, v) when they want
7413 to store duplicates; not DB[k] = v.

7769 of w# format code incorrectly truncated the length to an int, even
7770 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
7771 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007801- Added case insensitive comparison methods ``PyOS_stricmp(char*,
7802 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
