Florent Xiclunac2279652012-02-12 14:49:03 +0100907- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +0100908 has left two versions of customize_compiler, the original in
909 distutils.sysconfig and another copy in distutils.ccompiler, with some
910 parts of distutils calling one and others using the other.
911 Complete the revert back to only having one in distutils.sysconfig as
912 is the case in 3.x.
913
Ned Deily0d0ea482012-02-10 12:59:06 +0100914- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
915 Distutils-based packages with C extension modules may fail because
916 Apple has removed gcc-4.2, the version used to build python.org
917 64-bit/32-bit Pythons. If the user does not explicitly override
918 the default C compiler by setting the CC environment variable,
919 Distutils will now attempt to compile extension modules with clang
920 if gcc-4.2 is required but not found. Also as a convenience, if
921 the user does explicitly set CC, substitute its value as the default
922 compiler in the Distutils LDSHARED configuration variable for OS X.
923 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
924 SDK, neither of which are available in Xcode 4. This change does not
925 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001198- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1199 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1200 interpreter process. This could cause failures in non-Distutils subprocesses
1201 and was unreliable since tests or user programs could modify the interpreter
1202 environment after Distutils set it. Instead, have Distutils set the the
1203 deployment target only in the environment of each build subprocess. It is
1204 still possible to globally override the default by setting
1205 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1206 greater or equal to the default value, the value with which the interpreter
1207 was built.

1237 the ticker doesn't have to wind down to zero from the old starting point
1238 before the new interval takes effect. And if the user increases the
1239 interval, it makes sure the new limit takes effect right away rather have an
1240 early task switch before recognizing the new interval.

2048 the same behaviour than the print statement.

2064
2065 - format(complex(-0.0, 2.0), '-') omitted the real part from the output,
2066 - format(complex(0.0, 2.0), '-') included a sign and parentheses.

Raymond Hettinger20397532010-09-12 02:11:45 +00002191- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
2192 This prevents user-created self-referencing ordered dictionaries from
2193 becoming permanently uncollectable GC garbage. The downside is that
2194 removing __del__ means that the internal doubly-linked list has to wait for
2195 GC collection rather than freeing memory immediately when the refcnt drops
2196 to zero.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00002655- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
2656 start byte and the continuation byte(s) are now considered invalid, instead
2657 of the number of bytes specified by the start byte.
2658 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
2659 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
2660 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
2661 Previous versions returned a single u'\ufffd'.

2665 arises from the "Overriding __eq__ blocks inheritance ..." warning
2666 when turned into an exception: in this case the exception simply
2667 gets ignored.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00002669- Issue #8748: Fix two issues with comparisons between complex and integer
2670 objects. (1) The comparison could incorrectly return True in some cases
2671 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
2672 (2) The comparison raised an OverflowError for large integers, leading
2673 to unpredictable exceptions when combining integers and complex objects
2674 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +00002676- Issue #5211: Implicit coercion for the complex type is now completely
2677 removed. (Coercion for arithmetic operations was already removed in 2.7
2678 alpha 4, but coercion for rich comparisons was accidentally left in.)

3044 changed.

3057 with a non-empty format string. This is an effort to future-proof user
3058 code. If a derived class does not currently implement __format__ but later
3059 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00003060 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00003061 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00003111- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3112 InvalidOperation instead of returning False. (Comparisons involving a quiet
3113 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3114 signaling NaNs remain unhashable.

3118 returned an arbitrary result based on the relative ordering of id(float) and
3119 id(Decimal).

Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003121- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00003122 argument `-` which tells it to read files to compile from stdin. Each line is
3123 read on demand and the named file is compiled immediately. (Original patch by
3124 Piotr Ożarowski).

3134 Fractions instance now raise TypeError instead of returning True/False. This
3135 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3136 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00003573- Issue #7748: Since unicode values are supported for some metadata options in
3574 Distutils, the DistributionMetadata get_* methods will now return an utf-8
3575 encoded string for them. This ensures that the upload and register commands
3576 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00003653- The ``__complex__()`` method is now looked up on the class of instances to
3654 make it consistent with other special methods.

3658
Mark Dickinson1b34d252010-01-01 17:27:30 +00003659- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00003660 DeprecationWarning when passed a float argument where an integer was expected.
3661 These functions and methods now raise TypeError instead. The majority of the
3662 effects of this change are in the extension modules, but some core functions
3663 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3664 and many unicode/str methods.

3678 of integers: the result of a/b is now correctly rounded for ints a and b (at
3679 least on IEEE 754 platforms), and in particular does not depend on the
3680 internal representation of a long.

3688
Georg Brandlba83f822010-03-14 09:50:54 +00003689 These executables now work properly with the arch(1) command: ``arch -ppc
3690 python`` will start a universal binary version of python in PPC mode (unlike

Georg Brandlba83f822010-03-14 09:50:54 +00003826- Issue #7419: ``locale.setlocale()`` could crash the interpreter on Windows
3827 when called with invalid values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00003828
Georg Brandlba83f822010-03-14 09:50:54 +00003829- Issue #3382: 'F' formatting for float and complex now convert the result to
3830 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
3831 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00003832
Georg Brandlba83f822010-03-14 09:50:54 +00003833- Remove switch from "%f" formatting to "%g" formatting for floats larger than
3834 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00003835
Georg Brandlba83f822010-03-14 09:50:54 +00003836- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
3837 1e-100 used to raise OverflowError, but now gives the requested 120
3838 significant digits instead.
Mark Dickinson18cfada2009-11-23 18:46:41 +00003839
Georg Brandlba83f822010-03-14 09:50:54 +00003840- Add Py3k warnings for parameter names in parentheses.

Georg Brandlba83f822010-03-14 09:50:54 +00003842- Issue #7362: Give a proper error message for ``def f((x)=3): pass``.
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +00003843
Georg Brandlba83f822010-03-14 09:50:54 +00003844- Issue #7085: Fix crash when importing some extensions in a thread on MacOSX
3845 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +00003846
Georg Brandlba83f822010-03-14 09:50:54 +00003847- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3848 decimal string that's guaranteed to round back to x under correct rounding
3849 (with round-half-to-even rounding mode). Previously it gave a string based on
3850 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3851 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3852 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003853
Georg Brandlba83f822010-03-14 09:50:54 +00003854- Issue #7117: On almost all platforms: float-to-string and string-to-float
3855 conversions within Python are now correctly rounded. Places these conversions
3856 occur include: str for floats and complex numbers; the float and complex
3857 constructors; old-style and new-style numeric formatting; serialization and
3858 deserialization of floats and complex numbers using marshal, pickle and json;
3859 parsing of float and imaginary literals in Python code; Decimal-to-float
3860 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003861
Georg Brandlba83f822010-03-14 09:50:54 +00003862 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3863 providing correctly-rounded strtod and dtoa C functions. This code is
3864 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3865 the C compiler. There may be a small number of platforms on which correct
3866 operation of this code cannot be guaranteed, so the code is not used: notably,
3867 this applies to platforms where the C double format is not IEEE 754 binary64,
3868 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3869 and Python's configure script is unable to determine how to change the FPU
3870 precision. On these platforms conversions use the platform strtod and dtoa,
3871 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003872
Georg Brandlba83f822010-03-14 09:50:54 +00003873- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3874 uses the correctly-rounded string <-> float conversions described above (when
3875 available), and so produces correctly rounded results that will display nicely
3876 under the float repr. There are two related small changes: (1) round now
3877 accepts any class with an ``__index__()`` method for its second argument (but
3878 no longer accepts floats for the second argument), and (2) an excessively
3879 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3880 raises an exception.
Mark Dickinsonbd15a062009-11-18 19:33:35 +00003881
Philip Jenveyfab8be22009-11-17 02:42:26 +00003882- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
3883
Georg Brandlba83f822010-03-14 09:50:54 +00003884- Fix several issues with ``compile()``. The input can now contain Windows and
3885 Mac newlines and is no longer required to end in a newline.
Benjamin Petersone36199b2009-11-12 23:39:44 +00003886
Georg Brandlba83f822010-03-14 09:50:54 +00003887- Remove length limitation when constructing a complex number from a unicode
3888 string.
Mark Dickinsonc04c7c52009-10-26 22:28:14 +00003889
Georg Brandlba83f822010-03-14 09:50:54 +00003890- Issue #7244: ``itertools.izip_longest()`` no longer ignores exceptions raised

3909 should be no other effect than a small decrease in memory use. Patch by
3910 Christopher Tur Lesniewski-Laas.
Neil Schemenauer7fdd1cb2009-10-14 17:17:14 +00003911
Georg Brandlba83f822010-03-14 09:50:54 +00003912- Issue #7084: Fix a (very unlikely) crash when printing a list from one thread,
3913 and mutating it from another one. Patch by Scott Dial.
Antoine Pitroubeaf6a02009-10-11 21:03:26 +00003914
Amaury Forgeot d'Arcd0052d12009-10-06 19:56:32 +00003915- Issue #1571184: The Unicode database contains properties for more characters.
3916 The tables for code points representing numeric values, white spaces or line
3917 breaks are now generated from the official Unicode Character Database files,
3918 and include information from the Unihan.txt file.

Georg Brandlba83f822010-03-14 09:50:54 +00004027- Issue #5920: For ``float.__format__()``, change the behavior with the empty
4028 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
4029 but with at least one decimal point and with a default precision
4030 of 12. Previously, the behavior the same but with a default precision of 6.
4031 This more closely matches ``str()``, and reduces surprises when adding
4032 alignment flags to the empty presentation type. This also affects the new
4033 complex.__format__ in the same way.

Georg Brandlba83f822010-03-14 09:50:54 +00004098 untrackable objects are not tracked by the garbage collector. This can reduce
4099 the size of collections and therefore the garbage collection overhead on

Georg Brandl29c6a282009-04-05 20:23:13 +00004142- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +00004143 were suppressing all exceptions. These include list(), filter(), map(),

Georg Brandlba83f822010-03-14 09:50:54 +00004173- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
4174 existing .py counterpart, override the co_filename attributes of all code
4175 objects if the original filename is obsolete (which can happen if the file has

5666 ``printf`` function, whereas PyString_FromFormat has an independent
5667 implementation and uses "%zd" on all platforms for size_t values.
5668 This makes a difference on win64, where ``printf`` needs "%Id" to display
5669 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00005671- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
5672 error.
5673
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00005674- Issue #3777: long() applied to a float object now always return a long
5675 object; previously an int would be returned for small values. the __long__
5676 method is allowed to return either an int or a long, but the behaviour of
5677 float objects should not change to respect backward compatibility.
5678
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00005679- Issue #3751: str.rpartition would perform a left-partition when called with
5680 a unicode argument.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005684- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00005685 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005686 was correctly parsed but parsing of subsequent arguments failed.
5687
Vinay Sajip35e3b032008-09-01 14:33:59 +00005688- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005689 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5690 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5691 when given a tuple of classes as second argument, were looking up
5692 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5693 type object.
5694
Neal Norwitz18aa3882008-08-24 05:04:52 +00005695- Fix crashes on memory allocation failure found with failmalloc.

Brett Cannon1eaf0742008-09-02 01:25:16 +00005764 warnings.catch_warnings() along with some API cleanup. Expanding the tests
5765 for catch_warnings() also led to an improvement in the raising of a

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005832What's New in Python 2.6 beta 3?
5833================================
5834
Barry Warsaw07a4a382008-08-21 01:15:08 +00005835*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005836
5837Core and Builtins
5838-----------------
5839
Guido van Rossumf8402962008-08-20 15:01:50 +00005840- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5841 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5842 extensions do not automatically benefit from the class attribute
5843 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5844 to their tp_flags field if they care. This is a backwards
5845 compatibility feature; in 3.0, all types will use the cache by
5846 default.
5847
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005848- Keyword arguments can now follow starred arguments. (``f(a, *args,
5849 keyword=23)`` is now valid syntax.)
5850
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005851- ctypes function pointers that are COM methods have a boolean True
5852 value again.
5853
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005854- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5855 by denying s# to parse objects that have a releasebuffer procedure,
5856 and introducing s*.
5857
Georg Brandl1e13ea92008-08-11 09:07:59 +00005858- Issue #3537: Fix an assertion failure when an empty but presized dict
5859 object was stored in the freelist.
5860
Mark Dickinsonb6467572008-08-04 21:30:09 +00005861- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5862 ValueError consistently across platforms.
5863
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005864- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5865 (64bit Unix, for example), unichr() would truncate its argument and return
5866 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5867
Neal Norwitze7d8be82008-07-31 17:17:14 +00005868- Apply security patches from Apple.
5869
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005870- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5871 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5872
Antoine Pitrou92f82162008-07-25 22:22:08 +00005873- Issue #1819: function calls with several named parameters are now on
5874 average 35% faster (as measured by pybench).
5875
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005876- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5877 the python debugger steps into a class statement: the free variables (local
5878 variables defined in an outer scope) would be deleted from the outer scope.
5879
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005880- Issue #2620: Overflow checking when allocating or reallocating memory
5881 was not always being done properly in some python types and extension
5882 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5883 all been updated to perform better checks and places in the code that
5884 would previously leak memory on the error path when such an allocation
5885 failed have been fixed.

5891
Benjamin Petersone977ad42008-08-20 01:42:01 +00005892- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5893 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5894
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005895- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5896 version reported by these tools does not necessarily follow the python
5897 version numbering scheme, so the module is less strict when parsing it.
5898
Nick Coghlanf70385a2008-08-18 12:42:46 +00005899- Issue #2235: Added Py3k warnings for types which will become unhashable
5900 under the stricter __hash__ inheritance rules in 3.0. Several types
5901 which did not meet the rules for hash invariants and were already
5902 unhashable in 3.0 have now been explicitly flagged as unhashable in
5903 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5904 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5905
Brett Cannon88f801d2008-08-18 00:46:22 +00005906- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

5914
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005915- Issue #3575: Incremental decoder's decode function now takes bytearray
5916 by using 's*' instead of 't#'.
5917
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00005918- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00005919 fails unicode conversion on 2nd parameter. (windows only)

Brett Cannon721b1452008-08-16 22:00:27 +00005925 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00005926
Facundo Batistaeb90b782008-08-16 14:44:07 +00005927- Issue #2776: fixed small issue when handling an URL with double slash
5928 after a 302 response in the case of not going through a proxy.
5929
Antoine Pitroub90a8be2008-08-15 21:03:21 +00005930- Issue #2676: in the email package, content-type parsing was hanging on
5931 pathological input because of quadratic or exponential behaviour of a
5932 regular expression.
5933
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00005934- Issue #3476: binary buffered reading through the new "io" library is now
5935 thread-safe.
5936
Brett Cannonbf3157b2008-08-14 05:00:03 +00005937- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5938 since mimetools itself is deprecated. Because modules are cached, all
5939 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5940
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00005941- Issue #3134: shutil referenced undefined WindowsError symbol.
5942
Robert Schuppenies14646332008-08-10 11:01:53 +00005943- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
5944 menu entries were not deleted.
5945
Brett Cannon83e81842008-08-09 23:30:55 +00005946- Copied the implementation of reduce() to _functools.reduce() to have a
5947 version that did not raise a DeprecationWarning under -3.
5948
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00005949- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
5950 a MemoryError rather than silently stop the iteration.

6019
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00006020- Issue #643841: The language reference now provides more detailed

6033
Georg Brandl3e483f62008-07-16 22:57:41 +00006034- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6035 its methods now allow for items objects that can be converted to
6036 an integer using operator.index().
6037
Mark Dickinson64b7e502008-07-16 09:40:03 +00006038- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6039 produced a ValueError instead of giving the correct float.
6040
Eric Smitha5fa5a22008-07-16 00:11:49 +00006041- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6042 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.

Mark Dickinson7103aa42008-07-15 19:08:33 +00006044- Issue #3008: the float type has a new instance method 'float.hex'
6045 and a new class method 'float.fromhex' to convert floating-point
6046 numbers to and from hexadecimal strings, respectively.
6047
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006048- Issue #2235: __hash__ is once again inherited by default. To allow
6049 collections.Hashable to remain meaningful in the presence of the
6050 default hash implementation (object.__hash__), it is now possible
6051 to explicit block inheritance of hash by setting __hash__=None at
6052 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6053 level.

Nick Coghlanb028f502008-07-13 14:52:36 +00006055- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6056 the parent module cannot be found while performing an absolute import.
6057 This means that an incorrectly defined __package__ attribute will
6058 now only prevent relative imports in that module rather than causing
6059 all imports from that module to fail.
6060
Nick Coghlan14ff9942008-07-08 14:21:42 +00006061- Issue #2517: Allow unicode messages in Exceptions again by correctly

6071 another thread's dictionary.
6072
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006073- Issue #3004: Minor change to slice.indices(): the start and stop
6074 arguments are now treated identically, making the behaviour easier
6075 to describe and understand. For example, slice(None, -10,
6076 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6077 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6078 10, -1).

Georg Brandl278fc502008-07-19 12:46:12 +00006080- Issue #3219: Calling a function with repeated keyword arguments,

6121 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006122 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006123 content-length. The problem had been corrected in the 2.4 branch, but never

6527
Brett Cannonb61d8012008-05-11 23:39:04 +00006528- ``Lib/lib-old`` is now added to sys.path.
6529
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006530- On MacOS X it is now possible to install the framework in 64-bit
6531 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00006532 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006533
6534 This is controlled by the configure argument ``--with-universal-archs``:
6535
6536 - ``--with-universal-archs=all``: install 4-way universal
6537
6538 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6539
6540 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6541
6542 This option should be used in combination with ``--enable-universalsdk=``.
6543
6544 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Christian Heimes7a990612008-05-26 13:15:11 +00006553
6554- The PyString functions have been renamed to PyBytes. A batch of
6555 defines were added so that the linker still sees the original
6556 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006594- Issue #1631171: Re-implement the 'warnings' module in C (the
6595 original Python code has been kept as backup). This will allow for
6596 using the 'warning's machinery in such places as the parser where
6597 use of pure Python code is not possible. Both the ``showarning()``
6598 and ``formatwarning()`` gain an optional 'line' argument which is
6599 not called by default for backwards-compatibility reasons. Setting
6600 ``warnings.showwarning()`` to an implementation that lacks support
6601 for the ``line`` argument will raise a DeprecationWarning.

6625
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00006626- The getpass module has been improved on Unix. It now uses /dev/tty
6627 by default and uses stderr instead of stdout. A GetPassWarning is
6628 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00006629

Georg Brandl3ee81df2008-05-17 18:14:43 +00006643- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00006644 extension modules between 32 and 64 bit platforms. See the distutls

6657 so the controlled environment will more closely mirror the typical
6658 script environment. This supports setup.py scripts that refer to
6659 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006664- Issue #2550: The approach used by client/server code for obtaining
6665 ports to listen on in network-oriented tests has been refined in an
6666 effort to facilitate running multiple instances of the entire
6667 regression test suite in parallel without issue.
6668 test_support.bind_port() has been fixed such that it will always
6669 return a unique port -- which wasn't always the case with the
6670 previous implementation, especially if socket options had been set
6671 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6672 new implementation of bind_port() will actually raise an exception
6673 if it is passed an AF_INET/SOCK_STREAM socket with either the
6674 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6675 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6676 the socket it's been passed. This currently only applies to
6677 Windows. This option prevents any other sockets from binding to the
6678 host/port we've bound to, thus removing the possibility of the
6679 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6680 when a second SOCK_STREAM socket binds and accepts to a host/port
6681 that's already been bound by another socket. The optional preferred
6682 port parameter to bind_port() has been removed. Under no
6683 circumstances should tests be hard coding ports!
6684
6685 test_support.find_unused_port() has also been introduced, which will
6686 pass a temporary socket object to bind_port() in order to obtain an
6687 unused port. The temporary socket object is then closed and
6688 deleted, and the port is returned. This method should only be used
6689 for obtaining an unused port in order to pass to an external program
6690 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6691 a parameter to a server-oriented class that doesn't give you direct
6692 access to the underlying socket used.
6693
6694 Finally, test_support.HOST has been introduced, which should be used
6695 for the host argument of any relevant socket calls (i.e. bind and
6696 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006697
6698 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006699 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006700 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6701 test_asynchat and test_socket_ssl.
6702
Georg Brandl3ee81df2008-05-17 18:14:43 +00006703 It is now possible for multiple instances of the regression test
6704 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00006983- Added the future_builtins module, which contains hex() and oct().
6984 These are the PEP 3127 version of these functions, designed to be
6985 compatible with the hex() and oct() builtins from Python 3.0. They
6986 differ slightly in their output formats from the existing, unchanged
6987 Python 2.6 builtins. The expected usage of the future_builtins
6988 module is:
6989 from future_builtins import hex, oct
6990
Eric Smith7ef40bf2008-02-20 23:34:22 +00006991- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6992 exponents for exponents with absolute value < 100. Follows C99
6993 standard. This is a change on Windows, which would use 3 digits.
6994 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6995 so that any alterations it does to the resulting string will be
6996 available in stringlib/formatter.h (for float.__format__).
6997
Eric Smith5a3c1352008-02-19 13:21:56 +00006998- Implemented PEP 3101, Advanced String Formatting. This adds a new
6999 builtin format(); a format() method for str and unicode; a
7000 __format__() method to object, str, unicode, int, long, float, and
7001 datetime; the class string.Formatter; and the C API
7002 PyObject_Format().
7003
Georg Brandl3ee81df2008-05-17 18:14:43 +00007004- Fixed several potential crashes, all caused by specially crafted
7005 __del__ methods exploiting objects in temporarily inconsistent
7006 state.

7016 in order to allow pymalloc to free more arenas. Python may give back
7017 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007018
Georg Brandl3ee81df2008-05-17 18:14:43 +00007019- Issue #2045: Fix an infinite recursion triggered when printing a
7020 subclass of collections.defaultdict, if its default_factory is set
7021 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007022
Christian Heimesf75dbef2008-02-08 00:11:31 +00007023- Fixed a minor memory leak in dictobject.c. The content of the free
7024 list was not freed on interpreter shutdown.
7025
Georg Brandl21e99f42010-03-07 15:23:59 +00007026- Limit free list of method and built-in function objects to 256

7030 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00007031 to compact the internal free lists of pre-allocted ints and floats.
7032
Georg Brandl3ee81df2008-05-17 18:14:43 +00007033- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
7034 calls. Python expected the return type int but the fork familie

Georg Brandl3ee81df2008-05-17 18:14:43 +00007046- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
7047 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00007048
Georg Brandl3ee81df2008-05-17 18:14:43 +00007049- Patch #1473257: generator objects gain a gi_code attribute. This is
7050 the same object as the func_code attribute of the function that
7051 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007052
Georg Brandl3ee81df2008-05-17 18:14:43 +00007053- Issue #1920: "while 0" statements were completely removed by the
7054 compiler, even in the presence of an "else" clause, which is
7055 supposed to be run when the condition is false. Now the compiler
7056 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007057
Guido van Rossumeead05f2008-01-24 18:21:02 +00007058- A few crashers fixed: weakref_in_del.py (issue #1377858);
7059 loosing_dict_ref.py (issue #1303614, test67.py);
7060 borrowed_ref_[34].py (not in tracker).
7061
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00007062- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00007063 suppressed while an extension is loaded by calling SetErrorMode in
7064 dynload_win.c. The error is still reported properly.
7065
Georg Brandl3ee81df2008-05-17 18:14:43 +00007066- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007067 several extension methods and modules do not work without unicode
7068 support.
7069
Georg Brandl26543b12008-01-21 18:36:51 +00007070- Issue #1882: when compiling code from a string, encoding cookies in the
7071 second line of code were not always recognized correctly.
7072
Georg Brandl14404b62008-01-19 19:27:05 +00007073- Issue #1679: "0x" was taken as a valid integer literal.
7074
Georg Brandl6caad7d2008-01-26 14:19:22 +00007075- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007076 added.
7077
Christian Heimesc94e2b52008-01-14 04:13:37 +00007078- sys.float_info / PyFloat_GetInfo: The floating point information
7079 object was converted from a dict to a specialized structseq object.
7080
Georg Brandl3ee81df2008-05-17 18:14:43 +00007081- Patch #1816: Added sys.flags structseq. It exposes the status of
7082 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007083
Georg Brandl3ee81df2008-05-17 18:14:43 +00007084- Objects/structseq.c: Implemented new structseq representation. The
7085 patch makes structseqs (e.g. the return value of os.stat) more
7086 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007087
Georg Brandl3ee81df2008-05-17 18:14:43 +00007088- Patch #1700288: added a type attribute cache that caches method
7089 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00007090
Neal Norwitz3fc15b82008-01-10 05:42:58 +00007091- Bug #1776: __import__() no longer accepts filenames on any platform.
7092 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00007093
Georg Brandlaed6c662008-01-07 17:25:53 +00007094- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
7095
Georg Brandl3ee81df2008-05-17 18:14:43 +00007096- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
7097 envvar and sys.dont_write_bytecode attribute. All these can be set
7098 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007099
Georg Brandl3ee81df2008-05-17 18:14:43 +00007100- Improve some exception messages when Windows fails to load an
7101 extension module. Now we get for example '%1 is not a valid Win32
7102 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00007109- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00007110 and INF. float("nan"), float("inf") and float("-inf") now work on
7111 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00007112
Georg Brandl3ee81df2008-05-17 18:14:43 +00007113- Compiler now generates simpler and faster code for dictionary
7114 literals. The oparg for BUILD_MAP now indicates an estimated
7115 dictionary size. There is a new opcode, STORE_MAP, for adding
7116 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007145- Patch #1739468: Directories and zipfiles containing a __main__.py
7146 file can now be directly executed by passing their name to the
7147 interpreter. The directory/zipfile is automatically inserted as the
7148 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00007149
Georg Brandl3ee81df2008-05-17 18:14:43 +00007150- Issue #1265: Fix a problem with sys.settrace, if the tracing
7151 function uses a generator expression when at the same time the
7152 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00007153
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00007154- sets and frozensets now have an isdisjoint() method.
7155
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00007156- optimize the performance of builtin.sum().
7157
Neal Norwitz44f326e2007-10-05 05:29:17 +00007158- Fix warnings found by the new version of the Coverity checker.
7159
Georg Brandl21e99f42010-03-07 15:23:59 +00007160- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007161 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7162 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007163
Georg Brandl3ee81df2008-05-17 18:14:43 +00007164- Issue #1686386: Tuple's tp_repr did not take into account the
7165 possibility of having a self-referential tuple, which is possible
7166 from C code. Nor did object's tp_str consider that a type's tp_str
7167 could do something that could lead to an inifinite recursion.
7168 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7169 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007170
Georg Brandl3ee81df2008-05-17 18:14:43 +00007171- Issue #1164: It was possible to trigger deadlock when using the
7172 'print' statement to write to a file since the GIL was not released
7173 as needed. Now PyObject_Print() does the right thing along with
7174 various tp_print implementations of the built-in types and those in
7175 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007176
Georg Brandl3ee81df2008-05-17 18:14:43 +00007177- Issue #1147: Exceptions were directly allowing string exceptions in
7178 their throw() method even though string exceptions no longer
7179 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00007180
Georg Brandl3ee81df2008-05-17 18:14:43 +00007181- Issue #1096: Prevent a segfault from getting the repr of a very
7182 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00007183
Brett Cannon1e534b52007-09-07 04:18:30 +00007184- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007185 PyObject_Call() never calling back out to Python code to trigger
7186 recursion depth updates/checks. Required the creation of a static
7187 RuntimeError instance in case normalizing an exception put the
7188 recursion check value past its limit. Fixes crashers
7189 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00007190
Georg Brandl3ee81df2008-05-17 18:14:43 +00007191- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00007204- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00007205 __*__ attributes. (Some already existed, e.g., __doc__ and
7206 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00007207
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00007208- Add -3 option to the interpreter to warn about features that are
7209 deprecated and will be changed/removed in Python 3.0.
7210
Georg Brandl2134e752007-05-21 20:34:16 +00007211- Patch #1686487: you can now pass any mapping after '**' in function
7212 calls.
7213
Collin Winter62903052007-05-18 23:11:24 +00007214- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00007215 "except E as target:". This is to provide forwards compatibility
7216 with Python 3.0.

Brett Cannon229cee22007-05-05 01:34:02 +00007218- Deprecate BaseException.message as per PEP 352.
7219
Georg Brandl3ee81df2008-05-17 18:14:43 +00007220- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00007221 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00007222
Vinay Sajip8549ce32007-05-06 17:53:37 +00007223- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00007224 setting a plain string, ie don't expand to single letter identifiers.
7225
Raymond Hettinger13936692007-04-11 18:40:58 +00007226- Request #1191699: Slices can now be pickled.
7227
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00007228- Request #1193128: str.translate() now allows a None argument for
7229 translations that only remove characters without re-mapping the
7230 remaining characters.
7231
Georg Brandl5cb76c12007-03-21 09:00:39 +00007232- Patch #1682205: a TypeError while unpacking an iterable is no longer
7233 masked by a generic one with the message "unpack non-sequence".
7234
Neal Norwitzaa754b72007-03-21 06:39:48 +00007235- Remove unused file Python/fmod.c.
7236
Guido van Rossum143b5642007-03-23 04:58:42 +00007237- Bug #1683368: The object.__init__() and object.__new__() methods are
7238 now stricter in rejecting excess arguments. The only time when
7239 either allows excess arguments is when it is not overridden and the
7240 other one is. For backwards compatibility, when both are
7241 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007242 warning later). Also, type.__init__() insists on the same signature
7243 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00007244
Georg Brandl3ee81df2008-05-17 18:14:43 +00007245- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7246 object to complex using its __complex__() method before falling back
7247 to the __float__() method. Therefore, the functions in the cmath
7248 module now can operate on objects that define a __complex__()
7249 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007251- Patch #1623563: allow __class__ assignment for classes with
7252 __slots__. The old and the new class are still required to have the
7253 same slot names.

7259 ``object.__reduce_ex__()`` is called with an object that is faking
7260 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00007261
Georg Brandl3ee81df2008-05-17 18:14:43 +00007262- Patch #1680015: Don't modify __slots__ tuple if it contains an

7266
Georg Brandl7b9c5552007-03-12 14:30:05 +00007267- Bug #1678647: write a newline after printing an exception in any
7268 case, even when converting the value to a string failed.
7269
Georg Brandl871f1bc2007-03-12 13:17:36 +00007270- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007271 its argument, if it exists. If not, it will work like before. This
7272 allows customizing the output of dir() in the presence of a
7273 __getattr__().

Georg Brandl4e933132006-09-06 20:05:58 +00007388- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007406 generator expressions (x for x, in ... ) works again. Fixing this
7407 problem required changing the .pyc magic number. This means that
7408 .pyc files generated before 2.5c2 will be regenerated.

Guido van Rossum8bc09652008-02-21 18:18:37 +00007447- Removed uses of dict.has_key() from distutils, and uses of

Facundo Batistad918a652007-04-24 13:54:38 +00007796- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00007797 the client's request was successfully received, understood, and

Georg Brandl3ee81df2008-05-17 18:14:43 +00007838 AttributeError instead of an IOError when the server's response
7839 didn't contain a valid HTTP status line.

7930 TestCase and TestSuite subclasses (not instances) are no longer

Georg Brandl3ee81df2008-05-17 18:14:43 +00008323 time so that opening a database previously created with the DB_DUP
8324 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8325 opens. Specifically: dictionary assignment to a DB object will
8326 replace all values for a given key when the database allows
8327 duplicate values. DB users should use DB.put(k, v) when they want
8328 to store duplicates; not DB[k] = v.

8335 characters with ASCII value less than 32. Also, it correctly quotes
8336 dots only if they occur on a single line, as opposed to the previous
8337 behavior of quoting dots if they are the second character of any
8338 line.
