Ned Deily0d0ea482012-02-10 12:59:06 +0100838- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
839 Distutils-based packages with C extension modules may fail because
840 Apple has removed gcc-4.2, the version used to build python.org
841 64-bit/32-bit Pythons. If the user does not explicitly override
842 the default C compiler by setting the CC environment variable,
843 Distutils will now attempt to compile extension modules with clang
844 if gcc-4.2 is required but not found. Also as a convenience, if
845 the user does explicitly set CC, substitute its value as the default
846 compiler in the Distutils LDSHARED configuration variable for OS X.
847 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
848 SDK, neither of which are available in Xcode 4. This change does not
849 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001122- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1123 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1124 interpreter process. This could cause failures in non-Distutils subprocesses
1125 and was unreliable since tests or user programs could modify the interpreter
1126 environment after Distutils set it. Instead, have Distutils set the the
1127 deployment target only in the environment of each build subprocess. It is
1128 still possible to globally override the default by setting
1129 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1130 greater or equal to the default value, the value with which the interpreter
1131 was built.

1161 the ticker doesn't have to wind down to zero from the old starting point
1162 before the new interval takes effect. And if the user increases the
1163 interval, it makes sure the new limit takes effect right away rather have an
1164 early task switch before recognizing the new interval.

Raymond Hettinger20397532010-09-12 02:11:45 +00002115- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
2116 This prevents user-created self-referencing ordered dictionaries from
2117 becoming permanently uncollectable GC garbage. The downside is that
2118 removing __del__ means that the internal doubly-linked list has to wait for
2119 GC collection rather than freeing memory immediately when the refcnt drops
2120 to zero.

Philip Jenveyaebbaeb2010-04-06 23:24:45 +00002965- Issue #7301: Add environment variable $PYTHONWARNINGS.
2966
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00002967- Issue #8329: Don't return the same lists from select.select when no fds are
2968 changed.
2969
Georg Brandlfee0f442010-05-22 21:26:21 +00002970- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00002971 on 64-bit machines. The shift count for either left or right shift is
2972 permitted to be up to sys.maxsize.

2979
Georg Brandlfee0f442010-05-22 21:26:21 +00002980- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2981 with a non-empty format string. This is an effort to future-proof user
2982 code. If a derived class does not currently implement __format__ but later
2983 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002984 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002985 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00003018- Issue #8257: The Decimal construct now accepts a float instance directly,
3019 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00003020

Georg Brandlfee0f442010-05-22 21:26:21 +00003035- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3036 InvalidOperation instead of returning False. (Comparisons involving a quiet
3037 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3038 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00003039
Georg Brandlfee0f442010-05-22 21:26:21 +00003040- Issue #2531: Comparison operations between floats and Decimal instances now
3041 return a result based on the numeric values of the operands; previously they
3042 returned an arbitrary result based on the relative ordering of id(float) and
3043 id(Decimal).

Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003045- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00003046 argument `-` which tells it to read files to compile from stdin. Each line is
3047 read on demand and the named file is compiled immediately. (Original patch by

Florent Xicluna58b65662010-03-30 16:29:03 +00003053- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
3054 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00003055 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/

Georg Brandlfee0f442010-05-22 21:26:21 +00003057- Comparisons using one of <, <=, >, >= between a complex instance and a
3058 Fractions instance now raise TypeError instead of returning True/False. This
3059 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3060 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00003417- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
3418 and add the additional members returned in an OSVERSIONINFOEX structure. The
3419 new members are service_pack_major, service_pack_minor, suite_mask, and

Georg Brandlba83f822010-03-14 09:50:54 +00003422- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
3423 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
3424 returning NULL. The macro now returns a statically allocated empty string
3425 instead.

3435 strings,
3436 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
3437 numeric strings corresponding to subnormal values,
3438 (3) a memory leak for some values large enough to cause overflow, and
3439 (4) a number of flaws that could lead to incorrectly rounded results.

Antoine Pitroud840e512010-02-04 20:20:18 +00003470- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00003471 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00003472 Also, raise ValueError rather than TypeError when an unknown TIPC address
3473 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003477- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00003478 file position when calling `truncate()`. It would previously change the file
3479 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003480 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
3481
Georg Brandlba83f822010-03-14 09:50:54 +00003482- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
3483 class used to represent files stored inside an archive. The new
3484 implementation is significantly faster and can be wrapped in a
3485 ``io.BufferedReader`` object for more speedups. It also solves an issue
3486 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
3487 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +00003497- Issue #7748: Since unicode values are supported for some metadata options in
3498 Distutils, the DistributionMetadata get_* methods will now return an utf-8
3499 encoded string for them. This ensures that the upload and register commands
3500 send the correct values to PyPI without any error.

Benjamin Peterson4f51baf2009-12-05 18:40:02 +00003569What's New in Python 2.7 alpha 2?
3570=================================
3571
Benjamin Petersonaa7e51f2010-01-09 16:34:06 +00003572*Release date: 2010-01-09*

3575-----------------
3576
Georg Brandlba83f822010-03-14 09:50:54 +00003577- The ``__complex__()`` method is now looked up on the class of instances to
3578 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00003579
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00003580- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
3581 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
3582
Mark Dickinson1b34d252010-01-01 17:27:30 +00003583- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00003584 DeprecationWarning when passed a float argument where an integer was expected.
3585 These functions and methods now raise TypeError instead. The majority of the
3586 effects of this change are in the extension modules, but some core functions
3587 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3588 and many unicode/str methods.
Mark Dickinson1b34d252010-01-01 17:27:30 +00003589

Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +00003598- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
3599 used to drop the time part of the result.
3600
Georg Brandlba83f822010-03-14 09:50:54 +00003601- Issue #1811: Improve accuracy and cross-platform consistency for true division
3602 of integers: the result of a/b is now correctly rounded for ints a and b (at
3603 least on IEEE 754 platforms), and in particular does not depend on the
3604 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +00003605
Georg Brandlba83f822010-03-14 09:50:54 +00003606- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
3607 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
3608 in the subclass.
Ezio Melottif84caf42009-12-24 22:25:17 +00003609

Ronald Oussoren92919a62009-12-24 13:30:58 +00003611 executables on OSX.
3612
Georg Brandlba83f822010-03-14 09:50:54 +00003613 These executables now work properly with the arch(1) command: ``arch -ppc
3614 python`` will start a universal binary version of python in PPC mode (unlike
3615 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +00003616
Georg Brandlba83f822010-03-14 09:50:54 +00003617- Issue #1680159: Unicode coercion during an 'in' operation no longer masks the
3618 underlying error when the coercion fails for the left hand operand.
R. David Murray0a0a1a82009-12-14 16:28:26 +00003619

Georg Brandlba83f822010-03-14 09:50:54 +00003629- Issue #6963: Added "maxtasksperchild" argument to ``multiprocessing.Pool``,
3630 allowing for a maximum number of tasks within the pool to be completed by the
3631 worker before that worker is terminated, and a new one created to replace it.

Antoine Pitrou80157252010-01-08 19:20:17 +00003637- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
Georg Brandlba83f822010-03-14 09:50:54 +00003638 renaming of `cPickle` to `pickle`. The warning was annoying since there's no
3639 alternative to cPickle if you care about performance. Patch by Florent

Benjamin Petersonddd392c2009-12-13 19:19:07 +00003674- Issue #7349: Make methods of file objects in the io module accept None as an
3675 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
3676 the same as passing no argument.
3677
Georg Brandlba83f822010-03-14 09:50:54 +00003678- Issue #7348: ``StringIO.StringIO.readline(-1)`` now acts as if it got no

Mark Dickinsona36507c2010-01-30 10:08:33 +00003699
Georg Brandlba83f822010-03-14 09:50:54 +00003700- Issue #5080: The argument parsing functions ``PyArg_ParseTuple()``,
3701 ``PyArg_ParseTupleAndKeywords()``, ``PyArg_VaParse()``,
3702 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept
3703 float arguments for integer format codes (other than 'L'): previously an

Georg Brandlba83f822010-03-14 09:50:54 +00003771- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3772 decimal string that's guaranteed to round back to x under correct rounding
3773 (with round-half-to-even rounding mode). Previously it gave a string based on
3774 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3775 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3776 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003777
Georg Brandlba83f822010-03-14 09:50:54 +00003778- Issue #7117: On almost all platforms: float-to-string and string-to-float
3779 conversions within Python are now correctly rounded. Places these conversions
3780 occur include: str for floats and complex numbers; the float and complex
3781 constructors; old-style and new-style numeric formatting; serialization and
3782 deserialization of floats and complex numbers using marshal, pickle and json;
3783 parsing of float and imaginary literals in Python code; Decimal-to-float
3784 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003785
Georg Brandlba83f822010-03-14 09:50:54 +00003786 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3787 providing correctly-rounded strtod and dtoa C functions. This code is
3788 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3789 the C compiler. There may be a small number of platforms on which correct
3790 operation of this code cannot be guaranteed, so the code is not used: notably,
3791 this applies to platforms where the C double format is not IEEE 754 binary64,
3792 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3793 and Python's configure script is unable to determine how to change the FPU
3794 precision. On these platforms conversions use the platform strtod and dtoa,
3795 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003796
Georg Brandlba83f822010-03-14 09:50:54 +00003797- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3798 uses the correctly-rounded string <-> float conversions described above (when
3799 available), and so produces correctly rounded results that will display nicely
3800 under the float repr. There are two related small changes: (1) round now
3801 accepts any class with an ``__index__()`` method for its second argument (but
3802 no longer accepts floats for the second argument), and (2) an excessively
3803 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer

4031 internal representation of integers, for performance reasons. Base 2**30 is
4032 enabled by default on 64-bit machines. Add --enable-big-digits option to
4033 configure, which overrides the default. Add sys.long_info structseq to
4034 provide information about the internal format.

Georg Brandlba83f822010-03-14 09:50:54 +00004097- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
4098 existing .py counterpart, override the co_filename attributes of all code
4099 objects if the original filename is obsolete (which can happen if the file has

4154
Georg Brandlba83f822010-03-14 09:50:54 +00004155- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
4156 file objects with closefd=False. The file descriptor is still kept open but
4157 the file object behaves like a closed file. The ``FileIO`` object also got a
4158 new readonly attribute ``closefd``.

Georg Brandlba83f822010-03-14 09:50:54 +00004181- On windows, ``os.chdir()`` given unicode was not working if
4182 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
4183 this code path is really executed because I cannot move to such directory on
4184 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00004186- Issue #4069: When ``set.remove(element)`` is used with a set element, the
4187 element is temporarily replaced with an equivalent frozenset. But the
4188 eventual KeyError would always report the empty ``frozenset()`` as the missing
4189 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00004209- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
4210 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
4211 step. This avoids problems with counting UTF-8 bytes that ignores the effect
4212 of using the replace error handler in PyUnicode_DecodeUTF8().
4213
Walter Dörwald726ba8e2009-05-06 14:32:35 +00004214- Issue #3739: The unicode-internal encoder now reports the number of characters

Georg Brandlba83f822010-03-14 09:50:54 +00004217- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

5586
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005587- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5588 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5589 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5590 ``printf`` function, whereas PyString_FromFormat has an independent
5591 implementation and uses "%zd" on all platforms for size_t values.
5592 This makes a difference on win64, where ``printf`` needs "%Id" to display
5593 64bit values.

Antoine Pitrou0668c622008-08-26 22:42:08 +00005613 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5614 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5615 when given a tuple of classes as second argument, were looking up
5616 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5617 type object.

Brett Cannon1eaf0742008-09-02 01:25:16 +00005688 warnings.catch_warnings() along with some API cleanup. Expanding the tests
5689 for catch_warnings() also led to an improvement in the raising of a
5690 DeprecationWarning related to warnings.warn_explicit().
5691
Benjamin Peterson973e6c22008-09-01 23:12:58 +00005692- The deprecation warnings for the old camelCase threading API were removed.

5714
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00005715- Issue #2975: When compiling several extension modules with Visual Studio 2008
5716 from the same python interpreter, some environment variables would grow
5717 without limit.
5718
Benjamin Peterson37346b22008-08-23 20:27:43 +00005719- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
5720 exploitation of poor argument checking.
5721
Gerhard Häringef2276b2008-09-12 13:54:06 +00005722- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005756What's New in Python 2.6 beta 3?
5757================================
5758
Barry Warsaw07a4a382008-08-21 01:15:08 +00005759*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005760
5761Core and Builtins
5762-----------------
5763
Guido van Rossumf8402962008-08-20 15:01:50 +00005764- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5765 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5766 extensions do not automatically benefit from the class attribute
5767 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5768 to their tp_flags field if they care. This is a backwards
5769 compatibility feature; in 3.0, all types will use the cache by
5770 default.
5771
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005772- Keyword arguments can now follow starred arguments. (``f(a, *args,
5773 keyword=23)`` is now valid syntax.)
5774
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005775- ctypes function pointers that are COM methods have a boolean True
5776 value again.
5777
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005778- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5779 by denying s# to parse objects that have a releasebuffer procedure,
5780 and introducing s*.
5781
Georg Brandl1e13ea92008-08-11 09:07:59 +00005782- Issue #3537: Fix an assertion failure when an empty but presized dict
5783 object was stored in the freelist.
5784
Mark Dickinsonb6467572008-08-04 21:30:09 +00005785- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5786 ValueError consistently across platforms.
5787
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005788- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5789 (64bit Unix, for example), unichr() would truncate its argument and return
5790 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5791
Neal Norwitze7d8be82008-07-31 17:17:14 +00005792- Apply security patches from Apple.
5793
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005794- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5795 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5796
Antoine Pitrou92f82162008-07-25 22:22:08 +00005797- Issue #1819: function calls with several named parameters are now on
5798 average 35% faster (as measured by pybench).
5799
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005800- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5801 the python debugger steps into a class statement: the free variables (local
5802 variables defined in an outer scope) would be deleted from the outer scope.
5803
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005804- Issue #2620: Overflow checking when allocating or reallocating memory
5805 was not always being done properly in some python types and extension
5806 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5807 all been updated to perform better checks and places in the code that
5808 would previously leak memory on the error path when such an allocation
5809 failed have been fixed.
5810
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005811Library
5812-------
5813
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00005814- Issue #3612: Added some missing basic types in ctypes.wintypes.
5815
Benjamin Petersone977ad42008-08-20 01:42:01 +00005816- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5817 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5818
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005819- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5820 version reported by these tools does not necessarily follow the python
5821 version numbering scheme, so the module is less strict when parsing it.
5822
Nick Coghlanf70385a2008-08-18 12:42:46 +00005823- Issue #2235: Added Py3k warnings for types which will become unhashable
5824 under the stricter __hash__ inheritance rules in 3.0. Several types
5825 which did not meet the rules for hash invariants and were already
5826 unhashable in 3.0 have now been explicitly flagged as unhashable in
5827 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5828 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5829
Brett Cannon88f801d2008-08-18 00:46:22 +00005830- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
5831 imported into the module but exposed as part of the module's API.
5832
Brett Cannon7b96f072008-08-18 00:41:11 +00005833- Remove an unneeded import of abc.ABCMeta from 'inspect'.
5834
Brett Cannon46225e72008-08-18 00:36:52 +00005835- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00005837- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
5838
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005839- Issue #3575: Incremental decoder's decode function now takes bytearray
5840 by using 's*' instead of 't#'.
5841
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00005842- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00005843 fails unicode conversion on 2nd parameter. (windows only)
5844
Georg Brandl222e2082010-08-01 22:27:39 +00005845- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00005846 in a redirect.
5847
Brett Cannonabe423e2008-08-16 21:47:07 +00005848- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00005849 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00005850
Facundo Batistaeb90b782008-08-16 14:44:07 +00005851- Issue #2776: fixed small issue when handling an URL with double slash
5852 after a 302 response in the case of not going through a proxy.
5853
Antoine Pitroub90a8be2008-08-15 21:03:21 +00005854- Issue #2676: in the email package, content-type parsing was hanging on
5855 pathological input because of quadratic or exponential behaviour of a
5856 regular expression.
5857
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00005858- Issue #3476: binary buffered reading through the new "io" library is now
5859 thread-safe.
5860
Brett Cannonbf3157b2008-08-14 05:00:03 +00005861- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5862 since mimetools itself is deprecated. Because modules are cached, all
5863 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5864
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00005865- Issue #3134: shutil referenced undefined WindowsError symbol.
5866
Robert Schuppenies14646332008-08-10 11:01:53 +00005867- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
5868 menu entries were not deleted.
5869
Brett Cannon83e81842008-08-09 23:30:55 +00005870- Copied the implementation of reduce() to _functools.reduce() to have a
5871 version that did not raise a DeprecationWarning under -3.
5872
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00005873- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
5874 a MemoryError rather than silently stop the iteration.
5875
Guido van Rossum59ce9012008-08-09 14:55:34 +00005876- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5877 to _sre.compile() will now be rejected. This should not affect anybody
5878 since the re.compile() function never generates invalid re-bytecode.
5879
Skip Montanaroa032bf42008-08-08 22:52:51 +00005880- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5881 upon first access it can be automatically initialized from the csv file if
5882 it wasn't initialized during instantiation.
5883
Brett Cannon3aa2a492008-08-06 22:28:09 +00005884- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5885 the reload() built-in has been removed.
5886
Brett Cannon7e30b672008-08-04 21:52:25 +00005887- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00005888 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00005899 asking for a specific length. This problem only affected files opened
5900 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00005901

5926 file name rather than a ZipInfo instance, so files are extracted with
5927 mode 0600 rather than 000 under Unix.
5928

Raymond Hettingere3ae6552008-06-20 04:18:15 +00005955Core and Builtins
5956-----------------
5957
Georg Brandl3e483f62008-07-16 22:57:41 +00005958- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5959 its methods now allow for items objects that can be converted to
5960 an integer using operator.index().
5961
Mark Dickinson64b7e502008-07-16 09:40:03 +00005962- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5963 produced a ValueError instead of giving the correct float.
5964
Eric Smitha5fa5a22008-07-16 00:11:49 +00005965- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5966 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5967
Mark Dickinson7103aa42008-07-15 19:08:33 +00005968- Issue #3008: the float type has a new instance method 'float.hex'
5969 and a new class method 'float.fromhex' to convert floating-point
5970 numbers to and from hexadecimal strings, respectively.
5971
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005972- Issue #2235: __hash__ is once again inherited by default. To allow
5973 collections.Hashable to remain meaningful in the presence of the
5974 default hash implementation (object.__hash__), it is now possible
5975 to explicit block inheritance of hash by setting __hash__=None at
5976 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5977 level.
5978
Nick Coghlanb028f502008-07-13 14:52:36 +00005979- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5980 the parent module cannot be found while performing an absolute import.
5981 This means that an incorrectly defined __package__ attribute will
5982 now only prevent relative imports in that module rather than causing
5983 all imports from that module to fail.
5984
Nick Coghlan14ff9942008-07-08 14:21:42 +00005985- Issue #2517: Allow unicode messages in Exceptions again by correctly
5986 bypassing the instance dictionary when looking up __unicode__ on
5987 new-style classes.
5988
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00005989- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
5990 set to a custom object whose write() method happens to install
5991 another file in sys.stdout.
5992
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00005993- Issue #3088: Corrected a race condition in classes derived from
5994 threading.local: the first member set by a thread could be saved in
5995 another thread's dictionary.
5996
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005997- Issue #3004: Minor change to slice.indices(): the start and stop
5998 arguments are now treated identically, making the behaviour easier
5999 to describe and understand. For example, slice(None, -10,
6000 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6001 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6002 10, -1).
6003
Georg Brandl278fc502008-07-19 12:46:12 +00006004- Issue #3219: Calling a function with repeated keyword arguments,
6005 f(a=2, a=23), would not cause a syntax error. This was a regression
6006 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00006007
Georg Brandl278fc502008-07-19 12:46:12 +00006008- Issue #2862: Make int and float freelist management consistent with
6009 other freelists. Changes their CompactFreeList apis into
6010 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00006011

6013-------
6014
Thomas Heller57adf222008-08-14 19:10:48 +00006015- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
6016 api functions without holding the GIL, which could lead to a fatal
6017 error when they failed.
6018
Martin v. Löwisaabf4042008-08-02 07:20:25 +00006019- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.
6020
Jesse Noller7fb96402008-07-17 21:01:05 +00006021- Issue #3395: fix reference in test_multiprocessing to old debugInfo method

6026
Jesse Noller13e9d582008-07-16 14:32:36 +00006027- Issue #3125: Remove copy_reg in multiprocessing and replace it with
6028 ForkingPickler.register() to resolve conflict with ctypes.
6029
Vinay Sajip51e65192008-07-18 09:01:10 +00006030- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00006031
Thomas Heller880f5292008-07-15 19:39:38 +00006032- Issue #3313: Fixed a crash when a failed dlopen() call does not set
6033 a valid dlerror() message.
6034
Thomas Heller2bad6572008-07-15 17:19:50 +00006035- Issue #3258: Fixed a crash when a ctypes POINTER type to an
6036 incomplete structure was created.
6037
Brett Cannon3d0b9f02008-07-13 01:15:07 +00006038- Issue #3339: dummy_thread.acquire() should not return None.
6039
Raymond Hettingerb01713e2008-07-10 14:34:57 +00006040- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
6041
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006042- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00006043
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006044- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
6045 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006046 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006047 content-length. The problem had been corrected in the 2.4 branch, but never
6048 merged into trunk.
6049
Georg Brandle78fbcc2008-07-05 10:13:36 +00006050- Issue #2663: add filtering capability to shutil.copytree().

6053
6054- Issue #1526: Allow more than 64k files to be added to Zip64 file.
6055
6056- Issue #1746: Correct handling of zipfile archive comments (previously
6057 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00006058 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00006059
Vinay Sajip51e65192008-07-18 09:01:10 +00006060- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006061 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00006062
Nick Coghlanc060b0e2008-07-02 13:09:19 +00006063- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
6064 handling is now the same as that of other special attributes like __name__).
6065
Brett Cannon8bb8fa52008-07-02 01:57:08 +00006066- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
6067 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl3ee81df2008-05-17 18:14:43 +00006518- Issue #1631171: Re-implement the 'warnings' module in C (the
6519 original Python code has been kept as backup). This will allow for
6520 using the 'warning's machinery in such places as the parser where
6521 use of pure Python code is not possible. Both the ``showarning()``
6522 and ``formatwarning()`` gain an optional 'line' argument which is
6523 not called by default for backwards-compatibility reasons. Setting
6524 ``warnings.showwarning()`` to an implementation that lacks support
6525 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006588- Issue #2550: The approach used by client/server code for obtaining
6589 ports to listen on in network-oriented tests has been refined in an
6590 effort to facilitate running multiple instances of the entire
6591 regression test suite in parallel without issue.
6592 test_support.bind_port() has been fixed such that it will always
6593 return a unique port -- which wasn't always the case with the
6594 previous implementation, especially if socket options had been set
6595 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6596 new implementation of bind_port() will actually raise an exception
6597 if it is passed an AF_INET/SOCK_STREAM socket with either the
6598 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6599 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6600 the socket it's been passed. This currently only applies to
6601 Windows. This option prevents any other sockets from binding to the
6602 host/port we've bound to, thus removing the possibility of the
6603 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6604 when a second SOCK_STREAM socket binds and accepts to a host/port
6605 that's already been bound by another socket. The optional preferred
6606 port parameter to bind_port() has been removed. Under no
6607 circumstances should tests be hard coding ports!
6608
6609 test_support.find_unused_port() has also been introduced, which will
6610 pass a temporary socket object to bind_port() in order to obtain an
6611 unused port. The temporary socket object is then closed and
6612 deleted, and the port is returned. This method should only be used
6613 for obtaining an unused port in order to pass to an external program
6614 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6615 a parameter to a server-oriented class that doesn't give you direct
6616 access to the underlying socket used.
6617
6618 Finally, test_support.HOST has been introduced, which should be used
6619 for the host argument of any relevant socket calls (i.e. bind and
6620 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006621
6622 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006623 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006624 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6625 test_asynchat and test_socket_ssl.
6626
Georg Brandl3ee81df2008-05-17 18:14:43 +00006627 It is now possible for multiple instances of the regression test
6628 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00006907- Added the future_builtins module, which contains hex() and oct().
6908 These are the PEP 3127 version of these functions, designed to be
6909 compatible with the hex() and oct() builtins from Python 3.0. They
6910 differ slightly in their output formats from the existing, unchanged
6911 Python 2.6 builtins. The expected usage of the future_builtins
6912 module is:
6913 from future_builtins import hex, oct
6914
Eric Smith7ef40bf2008-02-20 23:34:22 +00006915- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6916 exponents for exponents with absolute value < 100. Follows C99
6917 standard. This is a change on Windows, which would use 3 digits.
6918 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6919 so that any alterations it does to the resulting string will be
6920 available in stringlib/formatter.h (for float.__format__).
6921
Eric Smith5a3c1352008-02-19 13:21:56 +00006922- Implemented PEP 3101, Advanced String Formatting. This adds a new
6923 builtin format(); a format() method for str and unicode; a
6924 __format__() method to object, str, unicode, int, long, float, and
6925 datetime; the class string.Formatter; and the C API
6926 PyObject_Format().
6927
Georg Brandl3ee81df2008-05-17 18:14:43 +00006928- Fixed several potential crashes, all caused by specially crafted
6929 __del__ methods exploiting objects in temporarily inconsistent
6930 state.

6941 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006942
Georg Brandl3ee81df2008-05-17 18:14:43 +00006943- Issue #2045: Fix an infinite recursion triggered when printing a
6944 subclass of collections.defaultdict, if its default_factory is set
6945 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006946
Christian Heimesf75dbef2008-02-08 00:11:31 +00006947- Fixed a minor memory leak in dictobject.c. The content of the free
6948 list was not freed on interpreter shutdown.
6949
Georg Brandl21e99f42010-03-07 15:23:59 +00006950- Limit free list of method and built-in function objects to 256

6954 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006955 to compact the internal free lists of pre-allocted ints and floats.
6956
Georg Brandl3ee81df2008-05-17 18:14:43 +00006957- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6958 calls. Python expected the return type int but the fork familie
6959 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006960

Georg Brandl3ee81df2008-05-17 18:14:43 +00006973- Patch #1473257: generator objects gain a gi_code attribute. This is
6974 the same object as the func_code attribute of the function that
6975 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006976
Georg Brandl3ee81df2008-05-17 18:14:43 +00006977- Issue #1920: "while 0" statements were completely removed by the
6978 compiler, even in the presence of an "else" clause, which is
6979 supposed to be run when the condition is false. Now the compiler
6980 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006981

6989
Georg Brandl3ee81df2008-05-17 18:14:43 +00006990- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006991 several extension methods and modules do not work without unicode
6992 support.
6993

6998
Georg Brandl6caad7d2008-01-26 14:19:22 +00006999- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007000 added.
7001
Christian Heimesc94e2b52008-01-14 04:13:37 +00007002- sys.float_info / PyFloat_GetInfo: The floating point information

Georg Brandl3ee81df2008-05-17 18:14:43 +00007024- Improve some exception messages when Windows fails to load an
7025 extension module. Now we get for example '%1 is not a valid Win32
7026 application' instead of 'error code 193'.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007034 and INF. float("nan"), float("inf") and float("-inf") now work on
7035 every platform with IEEE 754 semantics.

7039 dictionary size. There is a new opcode, STORE_MAP, for adding
7040 entries to the dictionary.

7070 file can now be directly executed by passing their name to the
7071 interpreter. The directory/zipfile is automatically inserted as the
7072 first entry in sys.path.

7083
Georg Brandl21e99f42010-03-07 15:23:59 +00007084- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007085 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7086 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007087
Georg Brandl3ee81df2008-05-17 18:14:43 +00007088- Issue #1686386: Tuple's tp_repr did not take into account the
7089 possibility of having a self-referential tuple, which is possible
7090 from C code. Nor did object's tp_str consider that a type's tp_str
7091 could do something that could lead to an inifinite recursion.
7092 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7093 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007094
Georg Brandl3ee81df2008-05-17 18:14:43 +00007095- Issue #1164: It was possible to trigger deadlock when using the
7096 'print' statement to write to a file since the GIL was not released
7097 as needed. Now PyObject_Print() does the right thing along with
7098 various tp_print implementations of the built-in types and those in
7099 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007100
Georg Brandl3ee81df2008-05-17 18:14:43 +00007101- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannon1e534b52007-09-07 04:18:30 +00007108- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007109 PyObject_Call() never calling back out to Python code to trigger
7110 recursion depth updates/checks. Required the creation of a static
7111 RuntimeError instance in case normalizing an exception put the
7112 recursion check value past its limit. Fixes crashers
7113 infinite_rec_(1|2|4|5).py.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007129 __*__ attributes. (Some already existed, e.g., __doc__ and
7130 __name__.)

7136 calls.
7137
Collin Winter62903052007-05-18 23:11:24 +00007138- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00007139 "except E as target:". This is to provide forwards compatibility
7140 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00007147- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00007148 setting a plain string, ie don't expand to single letter identifiers.
7149
Raymond Hettinger13936692007-04-11 18:40:58 +00007150- Request #1191699: Slices can now be pickled.
7151
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00007152- Request #1193128: str.translate() now allows a None argument for
7153 translations that only remove characters without re-mapping the
7154 remaining characters.
7155
Georg Brandl5cb76c12007-03-21 09:00:39 +00007156- Patch #1682205: a TypeError while unpacking an iterable is no longer

7160
Guido van Rossum143b5642007-03-23 04:58:42 +00007161- Bug #1683368: The object.__init__() and object.__new__() methods are
7162 now stricter in rejecting excess arguments. The only time when
7163 either allows excess arguments is when it is not overridden and the
7164 other one is. For backwards compatibility, when both are
7165 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007166 warning later). Also, type.__init__() insists on the same signature
7167 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00007168
Georg Brandl3ee81df2008-05-17 18:14:43 +00007169- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7170 object to complex using its __complex__() method before falling back
7171 to the __float__() method. Therefore, the functions in the cmath
7172 module now can operate on objects that define a __complex__()
7173 method.

7190
Georg Brandl7b9c5552007-03-12 14:30:05 +00007191- Bug #1678647: write a newline after printing an exception in any
7192 case, even when converting the value to a string failed.
7193
Georg Brandl871f1bc2007-03-12 13:17:36 +00007194- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007195 its argument, if it exists. If not, it will work like before. This
7196 allows customizing the output of dir() in the presence of a
7197 __getattr__().

7206 parthensized forms. This means complex(repr(x)) now works instead of
7207 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00007208
Georg Brandlaa2321b2007-03-07 00:40:28 +00007209- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007210 makes the filenames the warning module prints much more sensible
7211 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00007224- Patch #1674228: when assigning a slice (old-style), check for the
7225 sq_ass_slice instead of the sq_slice slot.
7226
Georg Brandl3ee81df2008-05-17 18:14:43 +00007227- When printing an unraisable error, don't print exceptions. before

7795
Georg Brandl92a6bae2007-03-13 17:43:32 +00007796- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00007797 are set for invalid interpolation sequences that would lead to
7798 errors on reading back those values.

7854 TestCase and TestSuite subclasses (not instances) are no longer
7855 accepted in TestSuite.addTest(). This should cause no

7857 -- the failure just occurred later, with a more cumbersome
7858 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00008145 that the SMTP.starttls() caller no longer needs to call ehlo()

Georg Brandl3ee81df2008-05-17 18:14:43 +00008147 does not claim to support starttls. Adds the
8148 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00008246- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00008247 time so that opening a database previously created with the DB_DUP
8248 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8249 opens. Specifically: dictionary assignment to a DB object will
8250 replace all values for a given key when the database allows
8251 duplicate values. DB users should use DB.put(k, v) when they want
8252 to store duplicates; not DB[k] = v.

8606
Georg Brandl3ee81df2008-05-17 18:14:43 +00008607- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
8608 of w# format code incorrectly truncated the length to an int, even
8609 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
8610 incorrect results with huge strings.

8634 outside of pystate.c and should not be necessary.
8635
Georg Brandl3ee81df2008-05-17 18:14:43 +00008636- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
8637 absolute imports. In earlier versions they might have used relative
8638 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00008639
Georg Brandl3ee81df2008-05-17 18:14:43 +00008640- Added case insensitive comparison methods ``PyOS_stricmp(char*,
8641 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00008642
Georg Brandl3ee81df2008-05-17 18:14:43 +00008643- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
