1093--------
1094
1095- As of 2.7.8, the 32-bit-only installer will support OS X 10.5
1096 and later systems as is currently done for Python 3.x installers.
1097 For 2.7.7 only, we will provide three installers:
1098 the legacy deprecated 10.3+ 32-bit-only format;
1099 the newer 10.5+ 32-bit-only format;
1100 and the unchanged 10.6+ 64-/32-bit format.
1101 Although binary installers will no longer be available from
1102 python.org as of 2.7.8, it will still be possible to build from
1103 source on 10.3.9 and 10.4 systems if necessary.
1104 See Mac/BuildScript/README.txt for more information.

2485 In particular, fix extension module build failures when trying to use
2486 32-bit-only installer Pythons on systems with Xcode 4 (currently
2487 OS X 10.8, 10.7, and optionally 10.6).
2488 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
2489 * Since Xcode 4 removes ppc support, extension module builds now
2490 check for ppc compiler support and by default remove ppc and
2491 ppc64 archs when they are not available.
2492 * Extension module builds now revert to using system installed
2493 headers and libs (/usr and /System/Library) if the SDK used
2494 to build the interpreter is not installed or has moved.
2495 * Try to avoid building extension modules with deprecated
2496 and problematic Apple llvm-gcc compiler. If original compiler
2497 is not available, use clang instead by default.

2942 Distutils-based packages with C extension modules may fail because
2943 Apple has removed gcc-4.2, the version used to build python.org
2944 64-bit/32-bit Pythons. If the user does not explicitly override
2945 the default C compiler by setting the CC environment variable,
2946 Distutils will now attempt to compile extension modules with clang
2947 if gcc-4.2 is required but not found. Also as a convenience, if
2948 the user does explicitly set CC, substitute its value as the default
2949 compiler in the Distutils LDSHARED configuration variable for OS X.
2950 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2951 SDK, neither of which are available in Xcode 4. This change does not
2952 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07003202- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
3203 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
3204 interpreter process. This could cause failures in non-Distutils subprocesses
3205 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02003206 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07003207 deployment target only in the environment of each build subprocess. It is
3208 still possible to globally override the default by setting
3209 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
3210 greater or equal to the default value, the value with which the interpreter
3211 was built.

3240 updating the check interval, so if the user decreases the check interval,
3241 the ticker doesn't have to wind down to zero from the old starting point
3242 before the new interval takes effect. And if the user increases the
3243 interval, it makes sure the new limit takes effect right away rather have an
3244 early task switch before recognizing the new interval.

Raymond Hettinger20397532010-09-12 02:11:45 +00004241- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
4242 This prevents user-created self-referencing ordered dictionaries from
4243 becoming permanently uncollectable GC garbage. The downside is that
4244 removing __del__ means that the internal doubly-linked list has to wait for
4245 GC collection rather than freeing memory immediately when the refcnt drops
4246 to zero.

4706 of the number of bytes specified by the start byte.
4707 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
4708 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte

Philip Jenveyaebbaeb2010-04-06 23:24:45 +00005090- Issue #7301: Add environment variable $PYTHONWARNINGS.
5091
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00005092- Issue #8329: Don't return the same lists from select.select when no fds are
5093 changed.
5094
Georg Brandlfee0f442010-05-22 21:26:21 +00005095- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00005096 on 64-bit machines. The shift count for either left or right shift is
5097 permitted to be up to sys.maxsize.

Georg Brandlfee0f442010-05-22 21:26:21 +00005105- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
5106 with a non-empty format string. This is an effort to future-proof user
5107 code. If a derived class does not currently implement __format__ but later
5108 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00005109 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00005110 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00005160- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
5161 InvalidOperation instead of returning False. (Comparisons involving a quiet
5162 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
5163 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00005164
Georg Brandlfee0f442010-05-22 21:26:21 +00005165- Issue #2531: Comparison operations between floats and Decimal instances now
5166 return a result based on the numeric values of the operands; previously they
5167 returned an arbitrary result based on the relative ordering of id(float) and
5168 id(Decimal).

Barry Warsawf7f2d6f2010-03-31 21:07:16 +00005170- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00005171 argument `-` which tells it to read files to compile from stdin. Each line is
5172 read on demand and the named file is compiled immediately. (Original patch by

Georg Brandlfee0f442010-05-22 21:26:21 +00005182- Comparisons using one of <, <=, >, >= between a complex instance and a
5183 Fractions instance now raise TypeError instead of returning True/False. This
5184 makes Fraction <=> complex comparisons consistent with int <=> complex, float
5185 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00005542- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
5543 and add the additional members returned in an OSVERSIONINFOEX structure. The
5544 new members are service_pack_major, service_pack_minor, suite_mask, and

Georg Brandlba83f822010-03-14 09:50:54 +00005547- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
5548 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
5549 returning NULL. The macro now returns a statically allocated empty string
5550 instead.

5560 strings,
5561 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
5562 numeric strings corresponding to subnormal values,
5563 (3) a memory leak for some values large enough to cause overflow, and
5564 (4) a number of flaws that could lead to incorrectly rounded results.

Georg Brandlba83f822010-03-14 09:50:54 +00005596 specified, rather than fall through to AF_PACKET (in the ``socket`` module).

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00005602- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00005603 file position when calling `truncate()`. It would previously change the file
5604 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00005605 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
5606
Georg Brandlba83f822010-03-14 09:50:54 +00005607- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
5608 class used to represent files stored inside an archive. The new
5609 implementation is significantly faster and can be wrapped in a
5610 ``io.BufferedReader`` object for more speedups. It also solves an issue
5611 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

5624 encoded string for them. This ensures that the upload and register commands
5625 send the correct values to PyPI without any error.

Benjamin Peterson4f51baf2009-12-05 18:40:02 +00005694What's New in Python 2.7 alpha 2?
5695=================================

5700-----------------
5701
Georg Brandlba83f822010-03-14 09:50:54 +00005702- The ``__complex__()`` method is now looked up on the class of instances to
5703 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00005704
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00005705- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
5706 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
5707
Mark Dickinson1b34d252010-01-01 17:27:30 +00005708- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00005709 DeprecationWarning when passed a float argument where an integer was expected.
5710 These functions and methods now raise TypeError instead. The majority of the
5711 effects of this change are in the extension modules, but some core functions
5712 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
5713 and many unicode/str methods.
Mark Dickinson1b34d252010-01-01 17:27:30 +00005714
Benjamin Peterson0f02d392009-12-30 19:34:10 +00005715- Issue #7604: Deleting an unset slotted attribute did not raise an
5716 AttributeError.

Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +00005723- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
5724 used to drop the time part of the result.
5725
Georg Brandlba83f822010-03-14 09:50:54 +00005726- Issue #1811: Improve accuracy and cross-platform consistency for true division
5727 of integers: the result of a/b is now correctly rounded for ints a and b (at
5728 least on IEEE 754 platforms), and in particular does not depend on the
5729 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +00005730
Georg Brandlba83f822010-03-14 09:50:54 +00005731- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
5732 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
5733 in the subclass.
Ezio Melottif84caf42009-12-24 22:25:17 +00005734

Ronald Oussoren92919a62009-12-24 13:30:58 +00005736 executables on OSX.
5737
Georg Brandlba83f822010-03-14 09:50:54 +00005738 These executables now work properly with the arch(1) command: ``arch -ppc
5739 python`` will start a universal binary version of python in PPC mode (unlike
5740 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +00005741
Georg Brandlba83f822010-03-14 09:50:54 +00005742- Issue #1680159: Unicode coercion during an 'in' operation no longer masks the
5743 underlying error when the coercion fails for the left hand operand.

5754 allowing for a maximum number of tasks within the pool to be completed by the
5755 worker before that worker is terminated, and a new one created to replace it.

Georg Brandlba83f822010-03-14 09:50:54 +00005762 renaming of `cPickle` to `pickle`. The warning was annoying since there's no
5763 alternative to cPickle if you care about performance. Patch by Florent

5800 the same as passing no argument.
5801
Georg Brandlba83f822010-03-14 09:50:54 +00005802- Issue #7348: ``StringIO.StringIO.readline(-1)`` now acts as if it got no

Georg Brandlba83f822010-03-14 09:50:54 +00005895- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
5896 decimal string that's guaranteed to round back to x under correct rounding
5897 (with round-half-to-even rounding mode). Previously it gave a string based on
5898 rounding x to 17 decimal digits. repr(x) for a complex number behaves
5899 similarly. On platforms where the correctly-rounded strtod and dtoa code is
5900 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005901
Georg Brandlba83f822010-03-14 09:50:54 +00005902- Issue #7117: On almost all platforms: float-to-string and string-to-float
5903 conversions within Python are now correctly rounded. Places these conversions
5904 occur include: str for floats and complex numbers; the float and complex
5905 constructors; old-style and new-style numeric formatting; serialization and
5906 deserialization of floats and complex numbers using marshal, pickle and json;
5907 parsing of float and imaginary literals in Python code; Decimal-to-float
5908 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005909
Georg Brandlba83f822010-03-14 09:50:54 +00005910 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
5911 providing correctly-rounded strtod and dtoa C functions. This code is
5912 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5913 the C compiler. There may be a small number of platforms on which correct
5914 operation of this code cannot be guaranteed, so the code is not used: notably,
5915 this applies to platforms where the C double format is not IEEE 754 binary64,
5916 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
5917 and Python's configure script is unable to determine how to change the FPU
5918 precision. On these platforms conversions use the platform strtod and dtoa,
5919 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005920
Georg Brandlba83f822010-03-14 09:50:54 +00005921- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5922 uses the correctly-rounded string <-> float conversions described above (when
5923 available), and so produces correctly rounded results that will display nicely
5924 under the float repr. There are two related small changes: (1) round now
5925 accepts any class with an ``__index__()`` method for its second argument (but
5926 no longer accepts floats for the second argument), and (2) an excessively
5927 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer

6155 internal representation of integers, for performance reasons. Base 2**30 is
6156 enabled by default on 64-bit machines. Add --enable-big-digits option to
6157 configure, which overrides the default. Add sys.long_info structseq to
6158 provide information about the internal format.

Georg Brandlba83f822010-03-14 09:50:54 +00006221- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
6222 existing .py counterpart, override the co_filename attributes of all code

6278
Georg Brandlba83f822010-03-14 09:50:54 +00006279- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
6280 file objects with closefd=False. The file descriptor is still kept open but
6281 the file object behaves like a closed file. The ``FileIO`` object also got a
6282 new readonly attribute ``closefd``.

Georg Brandlba83f822010-03-14 09:50:54 +00006305- On windows, ``os.chdir()`` given unicode was not working if
6306 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
6307 this code path is really executed because I cannot move to such directory on
6308 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00006310- Issue #4069: When ``set.remove(element)`` is used with a set element, the
6311 element is temporarily replaced with an equivalent frozenset. But the
6312 eventual KeyError would always report the empty ``frozenset()`` as the missing

6334 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
6335 step. This avoids problems with counting UTF-8 bytes that ignores the effect

6337
Walter Dörwald726ba8e2009-05-06 14:32:35 +00006338- Issue #3739: The unicode-internal encoder now reports the number of characters

Georg Brandlba83f822010-03-14 09:50:54 +00007529 - Packing a float now always gives a Deprecation Warning. Previously it
7530 only warned for 'I', 'L', '*B', '*H', '*I', '*L'.

Georg Brandlba83f822010-03-14 09:50:54 +00007532 - If x is not an int, long or float, then packing x will always result in
7533 struct.error. Previously an x with an __int__ method could be packed by
7534 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
7535 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
7536 neither __int__ nor __long__, TypeError used to be raised (with a
7537 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
7538 struct.error in other cases.

7541 argument with an __int__ method can be packed, but use of this feature
7542 triggers a DeprecationWarning.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00007735- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

7737 PY_FORMAT_SIZE_T is designed to select the correct format for the OS

Nick Coghland2e09382008-09-11 12:11:06 +00007809- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00007810 return a list or None rather than a custom object.
7811
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00007812- Issue #1638033: Cookie.Morsel gained the httponly attribute.

Brett Cannon1eaf0742008-09-02 01:25:16 +00007836 warnings.catch_warnings() along with some API cleanup. Expanding the tests
7837 for catch_warnings() also led to an improvement in the raising of a
7838 DeprecationWarning related to warnings.warn_explicit().
7839
Benjamin Peterson973e6c22008-09-01 23:12:58 +00007840- The deprecation warnings for the old camelCase threading API were removed.

7862
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00007863- Issue #2975: When compiling several extension modules with Visual Studio 2008
7864 from the same python interpreter, some environment variables would grow
7865 without limit.
7866
Benjamin Peterson37346b22008-08-23 20:27:43 +00007867- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
7868 exploitation of poor argument checking.
7869
Gerhard Häringef2276b2008-09-12 13:54:06 +00007870- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007904What's New in Python 2.6 beta 3?
7905================================
7906
Barry Warsaw07a4a382008-08-21 01:15:08 +00007907*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007908
7909Core and Builtins
7910-----------------
7911
Guido van Rossumf8402962008-08-20 15:01:50 +00007912- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
7913 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
7914 extensions do not automatically benefit from the class attribute
7915 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
7916 to their tp_flags field if they care. This is a backwards
7917 compatibility feature; in 3.0, all types will use the cache by
7918 default.
7919
Benjamin Petersonf647dc12008-08-20 01:27:30 +00007920- Keyword arguments can now follow starred arguments. (``f(a, *args,
7921 keyword=23)`` is now valid syntax.)
7922
Thomas Heller0ad5ae02008-08-19 19:25:04 +00007923- ctypes function pointers that are COM methods have a boolean True
7924 value again.
7925
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00007926- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
7927 by denying s# to parse objects that have a releasebuffer procedure,
7928 and introducing s*.
7929
Georg Brandl1e13ea92008-08-11 09:07:59 +00007930- Issue #3537: Fix an assertion failure when an empty but presized dict
7931 object was stored in the freelist.
7932
Mark Dickinsonb6467572008-08-04 21:30:09 +00007933- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
7934 ValueError consistently across platforms.
7935
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00007936- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
7937 (64bit Unix, for example), unichr() would truncate its argument and return
7938 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
7939
Neal Norwitze7d8be82008-07-31 17:17:14 +00007940- Apply security patches from Apple.
7941
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00007942- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
7943 PyErr_ExceptionMatches returns 0 when an exception occurs there.
7944
Antoine Pitrou92f82162008-07-25 22:22:08 +00007945- Issue #1819: function calls with several named parameters are now on
7946 average 35% faster (as measured by pybench).
7947
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00007948- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
7949 the python debugger steps into a class statement: the free variables (local
7950 variables defined in an outer scope) would be deleted from the outer scope.
7951
Gregory P. Smith0470bab2008-07-22 04:46:32 +00007952- Issue #2620: Overflow checking when allocating or reallocating memory
7953 was not always being done properly in some python types and extension
7954 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
7955 all been updated to perform better checks and places in the code that
7956 would previously leak memory on the error path when such an allocation
7957 failed have been fixed.
7958
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007959Library
7960-------
7961
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00007962- Issue #3612: Added some missing basic types in ctypes.wintypes.
7963
Benjamin Petersone977ad42008-08-20 01:42:01 +00007964- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
7965 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
7966
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00007967- Issue #2234: distutils failed for some versions of the cygwin compiler. The
7968 version reported by these tools does not necessarily follow the python
7969 version numbering scheme, so the module is less strict when parsing it.
7970
Nick Coghlanf70385a2008-08-18 12:42:46 +00007971- Issue #2235: Added Py3k warnings for types which will become unhashable
7972 under the stricter __hash__ inheritance rules in 3.0. Several types
7973 which did not meet the rules for hash invariants and were already
7974 unhashable in 3.0 have now been explicitly flagged as unhashable in
7975 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
7976 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
7977
Brett Cannon88f801d2008-08-18 00:46:22 +00007978- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

7980
Brett Cannon7b96f072008-08-18 00:41:11 +00007981- Remove an unneeded import of abc.ABCMeta from 'inspect'.
7982
Brett Cannon46225e72008-08-18 00:36:52 +00007983- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00007985- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
7986
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00007987- Issue #3575: Incremental decoder's decode function now takes bytearray
7988 by using 's*' instead of 't#'.
7989
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00007990- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00007991 fails unicode conversion on 2nd parameter. (windows only)
7992
Georg Brandl222e2082010-08-01 22:27:39 +00007993- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00007994 in a redirect.
7995
Brett Cannonabe423e2008-08-16 21:47:07 +00007996- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00007997 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00007998
Facundo Batistaeb90b782008-08-16 14:44:07 +00007999- Issue #2776: fixed small issue when handling an URL with double slash
8000 after a 302 response in the case of not going through a proxy.
8001
Antoine Pitroub90a8be2008-08-15 21:03:21 +00008002- Issue #2676: in the email package, content-type parsing was hanging on
8003 pathological input because of quadratic or exponential behaviour of a
8004 regular expression.
8005
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00008006- Issue #3476: binary buffered reading through the new "io" library is now
8007 thread-safe.
8008
Brett Cannonbf3157b2008-08-14 05:00:03 +00008009- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
8010 since mimetools itself is deprecated. Because modules are cached, all
8011 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
8012
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00008013- Issue #3134: shutil referenced undefined WindowsError symbol.
8014
Robert Schuppenies14646332008-08-10 11:01:53 +00008015- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
8016 menu entries were not deleted.
8017
Brett Cannon83e81842008-08-09 23:30:55 +00008018- Copied the implementation of reduce() to _functools.reduce() to have a
8019 version that did not raise a DeprecationWarning under -3.
8020
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00008021- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
8022 a MemoryError rather than silently stop the iteration.
8023
Guido van Rossum59ce9012008-08-09 14:55:34 +00008024- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
8025 to _sre.compile() will now be rejected. This should not affect anybody
8026 since the re.compile() function never generates invalid re-bytecode.
8027
Skip Montanaroa032bf42008-08-08 22:52:51 +00008028- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
8029 upon first access it can be automatically initialized from the csv file if
8030 it wasn't initialized during instantiation.
8031
Brett Cannon3aa2a492008-08-06 22:28:09 +00008032- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
8033 the reload() built-in has been removed.
8034
Brett Cannon7e30b672008-08-04 21:52:25 +00008035- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00008036 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00008047 asking for a specific length. This problem only affected files opened
8048 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00008049
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00008050- Issue #3449: Update decimal module to use most recent specification
8051 (v. 1.68) and tests (v. 2.58) from IBM.

8057
Georg Brandlf9efabb2008-07-23 15:16:45 +00008058- Deprecate the "ast" parser function aliases.

8072
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00008073- Issue #3394: zipfile.writestr sets external attributes when passed a
8074 file name rather than a ZipInfo instance, so files are extracted with
8075 mode 0600 rather than 000 under Unix.
8076
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00008077- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
8078 argument in python 2.5, this broke code that subclassed Popen to include its
8079 own poll method. Fixed my moving _deadstate to an _internal_poll method.

8091
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00008092- Issue #643841: The language reference now provides more detailed
8093 coverage of the lookup process for special methods. The disclaimers
8094 regarding lack of coverage of new-style classes have also been

8099================================
8100
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00008101*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00008103Core and Builtins
8104-----------------
8105
Georg Brandl3e483f62008-07-16 22:57:41 +00008106- Issue #3156: Fix inconsistent behavior of the bytearray type: all
8107 its methods now allow for items objects that can be converted to
8108 an integer using operator.index().
8109
Mark Dickinson64b7e502008-07-16 09:40:03 +00008110- Issue #3360: Fix incorrect parsing of '020000000000.0', which
8111 produced a ValueError instead of giving the correct float.
8112
Eric Smitha5fa5a22008-07-16 00:11:49 +00008113- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
8114 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
8115
Mark Dickinson7103aa42008-07-15 19:08:33 +00008116- Issue #3008: the float type has a new instance method 'float.hex'
8117 and a new class method 'float.fromhex' to convert floating-point
8118 numbers to and from hexadecimal strings, respectively.
8119
Nick Coghlan6d6bd442008-07-15 15:40:22 +00008120- Issue #2235: __hash__ is once again inherited by default. To allow
8121 collections.Hashable to remain meaningful in the presence of the
8122 default hash implementation (object.__hash__), it is now possible
8123 to explicit block inheritance of hash by setting __hash__=None at
8124 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
8125 level.
8126
Nick Coghlanb028f502008-07-13 14:52:36 +00008127- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
8128 the parent module cannot be found while performing an absolute import.
8129 This means that an incorrectly defined __package__ attribute will
8130 now only prevent relative imports in that module rather than causing
8131 all imports from that module to fail.
8132
Nick Coghlan14ff9942008-07-08 14:21:42 +00008133- Issue #2517: Allow unicode messages in Exceptions again by correctly
8134 bypassing the instance dictionary when looking up __unicode__ on
8135 new-style classes.

8138 set to a custom object whose write() method happens to install
8139 another file in sys.stdout.

8142 threading.local: the first member set by a thread could be saved in
8143 another thread's dictionary.
8144
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00008145- Issue #3004: Minor change to slice.indices(): the start and stop
8146 arguments are now treated identically, making the behaviour easier
8147 to describe and understand. For example, slice(None, -10,
8148 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
8149 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
8150 10, -1).
8151
Georg Brandl278fc502008-07-19 12:46:12 +00008152- Issue #3219: Calling a function with repeated keyword arguments,
8153 f(a=2, a=23), would not cause a syntax error. This was a regression
8154 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00008155
Georg Brandl278fc502008-07-19 12:46:12 +00008156- Issue #2862: Make int and float freelist management consistent with
8157 other freelists. Changes their CompactFreeList apis into

8164 api functions without holding the GIL, which could lead to a fatal
8165 error when they failed.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00008192- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
8193 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00008194 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00008195 content-length. The problem had been corrected in the 2.4 branch, but never
8196 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00008211- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
8212 handling is now the same as that of other special attributes like __name__).
8213
Brett Cannon8bb8fa52008-07-02 01:57:08 +00008214- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

8664 original Python code has been kept as backup). This will allow for
8665 using the 'warning's machinery in such places as the parser where
8666 use of pure Python code is not possible. Both the ``showarning()``
8667 and ``formatwarning()`` gain an optional 'line' argument which is
8668 not called by default for backwards-compatibility reasons. Setting
8669 ``warnings.showwarning()`` to an implementation that lacks support
8670 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008733- Issue #2550: The approach used by client/server code for obtaining
8734 ports to listen on in network-oriented tests has been refined in an
8735 effort to facilitate running multiple instances of the entire
8736 regression test suite in parallel without issue.
8737 test_support.bind_port() has been fixed such that it will always
8738 return a unique port -- which wasn't always the case with the
8739 previous implementation, especially if socket options had been set
8740 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
8741 new implementation of bind_port() will actually raise an exception
8742 if it is passed an AF_INET/SOCK_STREAM socket with either the
8743 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
8744 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
8745 the socket it's been passed. This currently only applies to
8746 Windows. This option prevents any other sockets from binding to the
8747 host/port we've bound to, thus removing the possibility of the
8748 'non-deterministic' behaviour, as Microsoft puts it, that occurs
8749 when a second SOCK_STREAM socket binds and accepts to a host/port
8750 that's already been bound by another socket. The optional preferred
8751 port parameter to bind_port() has been removed. Under no
8752 circumstances should tests be hard coding ports!
8753
8754 test_support.find_unused_port() has also been introduced, which will
8755 pass a temporary socket object to bind_port() in order to obtain an
8756 unused port. The temporary socket object is then closed and
8757 deleted, and the port is returned. This method should only be used
8758 for obtaining an unused port in order to pass to an external program
8759 (i.e. the -accept [port] argument to openssl's s_server mode) or as
8760 a parameter to a server-oriented class that doesn't give you direct
8761 access to the underlying socket used.
8762
8763 Finally, test_support.HOST has been introduced, which should be used
8764 for the host argument of any relevant socket calls (i.e. bind and
8765 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00008766
8767 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00008768 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00008769 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
8770 test_asynchat and test_socket_ssl.
8771
Georg Brandl3ee81df2008-05-17 18:14:43 +00008772 It is now possible for multiple instances of the regression test
8773 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00009052- Added the future_builtins module, which contains hex() and oct().
9053 These are the PEP 3127 version of these functions, designed to be
9054 compatible with the hex() and oct() builtins from Python 3.0. They
9055 differ slightly in their output formats from the existing, unchanged
9056 Python 2.6 builtins. The expected usage of the future_builtins
9057 module is:
9058 from future_builtins import hex, oct
9059
Eric Smith7ef40bf2008-02-20 23:34:22 +00009060- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
9061 exponents for exponents with absolute value < 100. Follows C99
9062 standard. This is a change on Windows, which would use 3 digits.
9063 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
9064 so that any alterations it does to the resulting string will be
9065 available in stringlib/formatter.h (for float.__format__).
9066
Eric Smith5a3c1352008-02-19 13:21:56 +00009067- Implemented PEP 3101, Advanced String Formatting. This adds a new
9068 builtin format(); a format() method for str and unicode; a
9069 __format__() method to object, str, unicode, int, long, float, and
9070 datetime; the class string.Formatter; and the C API
9071 PyObject_Format().
9072
Georg Brandl3ee81df2008-05-17 18:14:43 +00009073- Fixed several potential crashes, all caused by specially crafted
9074 __del__ methods exploiting objects in temporarily inconsistent
9075 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00009076
Vinay Sajipb7edfc42008-04-02 21:10:23 +00009077- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00009078 prevent a possible crash: an Abstract Base Class would try to access
9079 a slot on a registered virtual subclass.

9085 in order to allow pymalloc to free more arenas. Python may give back
9086 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00009087
Georg Brandl3ee81df2008-05-17 18:14:43 +00009088- Issue #2045: Fix an infinite recursion triggered when printing a
9089 subclass of collections.defaultdict, if its default_factory is set
9090 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00009091
Christian Heimesf75dbef2008-02-08 00:11:31 +00009092- Fixed a minor memory leak in dictobject.c. The content of the free
9093 list was not freed on interpreter shutdown.
9094
Georg Brandl21e99f42010-03-07 15:23:59 +00009095- Limit free list of method and built-in function objects to 256

9099 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00009100 to compact the internal free lists of pre-allocted ints and floats.
9101
Georg Brandl3ee81df2008-05-17 18:14:43 +00009102- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
9103 calls. Python expected the return type int but the fork familie
9104 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00009105

Georg Brandl3ee81df2008-05-17 18:14:43 +00009118- Patch #1473257: generator objects gain a gi_code attribute. This is
9119 the same object as the func_code attribute of the function that
9120 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00009121
Georg Brandl3ee81df2008-05-17 18:14:43 +00009122- Issue #1920: "while 0" statements were completely removed by the
9123 compiler, even in the presence of an "else" clause, which is
9124 supposed to be run when the condition is false. Now the compiler
9125 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00009126
Guido van Rossumeead05f2008-01-24 18:21:02 +00009127- A few crashers fixed: weakref_in_del.py (issue #1377858);
9128 loosing_dict_ref.py (issue #1303614, test67.py);
9129 borrowed_ref_[34].py (not in tracker).

9134
Georg Brandl3ee81df2008-05-17 18:14:43 +00009135- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00009136 several extension methods and modules do not work without unicode
9137 support.
9138

Georg Brandl14404b62008-01-19 19:27:05 +00009142- Issue #1679: "0x" was taken as a valid integer literal.
9143
Georg Brandl6caad7d2008-01-26 14:19:22 +00009144- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00009145 added.
9146
Christian Heimesc94e2b52008-01-14 04:13:37 +00009147- sys.float_info / PyFloat_GetInfo: The floating point information
9148 object was converted from a dict to a specialized structseq object.
9149
Georg Brandl3ee81df2008-05-17 18:14:43 +00009150- Patch #1816: Added sys.flags structseq. It exposes the status of
9151 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00009152
Georg Brandl3ee81df2008-05-17 18:14:43 +00009153- Objects/structseq.c: Implemented new structseq representation. The

Georg Brandl3ee81df2008-05-17 18:14:43 +00009157- Patch #1700288: added a type attribute cache that caches method
9158 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00009159
Neal Norwitz3fc15b82008-01-10 05:42:58 +00009160- Bug #1776: __import__() no longer accepts filenames on any platform.
9161 The first parameter to __import__() must be a valid module name.

Georg Brandlaed6c662008-01-07 17:25:53 +00009163- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
9164
Georg Brandl3ee81df2008-05-17 18:14:43 +00009165- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
9166 envvar and sys.dont_write_bytecode attribute. All these can be set
9167 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00009168
Georg Brandl3ee81df2008-05-17 18:14:43 +00009169- Improve some exception messages when Windows fails to load an
9170 extension module. Now we get for example '%1 is not a valid Win32
9171 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00009178- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00009179 and INF. float("nan"), float("inf") and float("-inf") now work on
9180 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009182- Compiler now generates simpler and faster code for dictionary
9183 literals. The oparg for BUILD_MAP now indicates an estimated
9184 dictionary size. There is a new opcode, STORE_MAP, for adding
9185 entries to the dictionary.

9197
Nick Coghlanef01d822007-12-03 12:55:17 +00009198- PEP 366: Allow explicit relative imports when executing modules

Georg Brandl3ee81df2008-05-17 18:14:43 +00009214- Patch #1739468: Directories and zipfiles containing a __main__.py
9215 file can now be directly executed by passing their name to the
9216 interpreter. The directory/zipfile is automatically inserted as the
9217 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00009218
Georg Brandl3ee81df2008-05-17 18:14:43 +00009219- Issue #1265: Fix a problem with sys.settrace, if the tracing
9220 function uses a generator expression when at the same time the
9221 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00009222
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00009223- sets and frozensets now have an isdisjoint() method.
9224
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00009225- optimize the performance of builtin.sum().
9226
Neal Norwitz44f326e2007-10-05 05:29:17 +00009227- Fix warnings found by the new version of the Coverity checker.
9228
Georg Brandl21e99f42010-03-07 15:23:59 +00009229- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00009230 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
9231 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00009232
Georg Brandl3ee81df2008-05-17 18:14:43 +00009233- Issue #1686386: Tuple's tp_repr did not take into account the
9234 possibility of having a self-referential tuple, which is possible
9235 from C code. Nor did object's tp_str consider that a type's tp_str
9236 could do something that could lead to an inifinite recursion.
9237 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
9238 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00009239
Georg Brandl3ee81df2008-05-17 18:14:43 +00009240- Issue #1164: It was possible to trigger deadlock when using the
9241 'print' statement to write to a file since the GIL was not released
9242 as needed. Now PyObject_Print() does the right thing along with
9243 various tp_print implementations of the built-in types and those in
9244 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00009245
Georg Brandl3ee81df2008-05-17 18:14:43 +00009246- Issue #1147: Exceptions were directly allowing string exceptions in
9247 their throw() method even though string exceptions no longer
9248 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00009249
Georg Brandl3ee81df2008-05-17 18:14:43 +00009250- Issue #1096: Prevent a segfault from getting the repr of a very
9251 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00009252
Brett Cannon1e534b52007-09-07 04:18:30 +00009253- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00009254 PyObject_Call() never calling back out to Python code to trigger
9255 recursion depth updates/checks. Required the creation of a static
9256 RuntimeError instance in case normalizing an exception put the
9257 recursion check value past its limit. Fixes crashers
9258 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00009259
Georg Brandl3ee81df2008-05-17 18:14:43 +00009260- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00009273- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00009274 __*__ attributes. (Some already existed, e.g., __doc__ and
9275 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00009276
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00009277- Add -3 option to the interpreter to warn about features that are
9278 deprecated and will be changed/removed in Python 3.0.
9279
Georg Brandl2134e752007-05-21 20:34:16 +00009280- Patch #1686487: you can now pass any mapping after '**' in function
9281 calls.
9282
Collin Winter62903052007-05-18 23:11:24 +00009283- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00009284 "except E as target:". This is to provide forwards compatibility
9285 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00009286
Brett Cannon229cee22007-05-05 01:34:02 +00009287- Deprecate BaseException.message as per PEP 352.
9288
Georg Brandl3ee81df2008-05-17 18:14:43 +00009289- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00009290 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00009291
Vinay Sajip8549ce32007-05-06 17:53:37 +00009292- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00009293 setting a plain string, ie don't expand to single letter identifiers.
9294
Raymond Hettinger13936692007-04-11 18:40:58 +00009295- Request #1191699: Slices can now be pickled.
9296
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00009297- Request #1193128: str.translate() now allows a None argument for
9298 translations that only remove characters without re-mapping the
9299 remaining characters.
9300
Georg Brandl5cb76c12007-03-21 09:00:39 +00009301- Patch #1682205: a TypeError while unpacking an iterable is no longer
9302 masked by a generic one with the message "unpack non-sequence".
9303
Neal Norwitzaa754b72007-03-21 06:39:48 +00009304- Remove unused file Python/fmod.c.
9305
Guido van Rossum143b5642007-03-23 04:58:42 +00009306- Bug #1683368: The object.__init__() and object.__new__() methods are
9307 now stricter in rejecting excess arguments. The only time when
9308 either allows excess arguments is when it is not overridden and the
9309 other one is. For backwards compatibility, when both are
9310 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00009311 warning later). Also, type.__init__() insists on the same signature
9312 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00009313
Georg Brandl3ee81df2008-05-17 18:14:43 +00009314- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
9315 object to complex using its __complex__() method before falling back
9316 to the __float__() method. Therefore, the functions in the cmath
9317 module now can operate on objects that define a __complex__()
9318 method.
Georg Brandl2b869942007-03-17 16:08:45 +00009319
Georg Brandl3ee81df2008-05-17 18:14:43 +00009320- Patch #1623563: allow __class__ assignment for classes with
9321 __slots__. The old and the new class are still required to have the
9322 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00009323
Georg Brandl3ee81df2008-05-17 18:14:43 +00009324- Patch #1642547: Fix an error/crash when encountering syntax errors

9328 ``object.__reduce_ex__()`` is called with an object that is faking
9329 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00009330
Georg Brandl3ee81df2008-05-17 18:14:43 +00009331- Patch #1680015: Don't modify __slots__ tuple if it contains an

9335
Georg Brandl7b9c5552007-03-12 14:30:05 +00009336- Bug #1678647: write a newline after printing an exception in any
9337 case, even when converting the value to a string failed.
9338
Georg Brandl871f1bc2007-03-12 13:17:36 +00009339- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00009340 its argument, if it exists. If not, it will work like before. This
9341 allows customizing the output of dir() in the presence of a
9342 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00009343
Collin Winter276887b2007-03-12 16:11:39 +00009344- Patch #922167: Python no longer segfaults when faced with infinitely
9345 self-recursive reload() calls (as reported by bug #742342).
9346
Georg Brandl3ee81df2008-05-17 18:14:43 +00009347- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00009350- Patch #1491866: change the complex() constructor to allow
9351 parthensized forms. This means complex(repr(x)) now works instead of
9352 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00009353
Georg Brandlaa2321b2007-03-07 00:40:28 +00009354- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00009355 makes the filenames the warning module prints much more sensible
9356 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00009357
Georg Brandl49aafc92007-03-07 00:34:46 +00009358- Variant of patch #697613: don't exit the interpreter on a SystemExit
9359 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00009360 variable is given, but break into the interactive interpreter just
9361 like on other exceptions or normal program exit.

Georg Brandl098cd692007-03-06 12:17:50 +00009368
Georg Brandl0fca97a2007-03-05 22:28:08 +00009369- Patch #1674228: when assigning a slice (old-style), check for the
9370 sq_ass_slice instead of the sq_slice slot.
9371
Georg Brandl3ee81df2008-05-17 18:14:43 +00009372- When printing an unraisable error, don't print exceptions. before
9373 the name. This duplicates the behavior whening normally printing
9374 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00009375
Georg Brandl3ee81df2008-05-17 18:14:43 +00009376- Bug #1653736: Properly discard third argument to

Georg Brandl92a6bae2007-03-13 17:43:32 +00009940- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00009941 are set for invalid interpolation sequences that would lead to
9942 errors on reading back those values.

9998 TestCase and TestSuite subclasses (not instances) are no longer

10001 -- the failure just occurred later, with a more cumbersome
10002 exception.

10367 complex, tuple, list, dict, set, and frozenset. Formerly, it would
10368 silently miscode subclasses of those types. Now, it raises a

Gregory P. Smithec10a4a2007-11-05 02:32:26 +000010384- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +000010385 time so that opening a database previously created with the DB_DUP
10386 or DB_DUPSORT flag set will keep the proper behavior on subsequent
10387 opens. Specifically: dictionary assignment to a DB object will
10388 replace all values for a given key when the database allows
10389 duplicate values. DB users should use DB.put(k, v) when they want
10390 to store duplicates; not DB[k] = v.

10397 characters with ASCII value less than 32. Also, it correctly quotes
10398 dots only if they occur on a single line, as opposed to the previous
10399 behavior of quoting dots if they are the second character of any
10400 line.
