1417 32-bit-only installer Pythons on systems with Xcode 4 (currently
1418 OS X 10.8, 10.7, and optionally 10.6).
1419 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1420 * Since Xcode 4 removes ppc support, extension module builds now
1421 check for ppc compiler support and by default remove ppc and
1422 ppc64 archs when they are not available.
1423 * Extension module builds now revert to using system installed
1424 headers and libs (/usr and /System/Library) if the SDK used
1425 to build the interpreter is not installed or has moved.
1426 * Try to avoid building extension modules with deprecated
1427 and problematic Apple llvm-gcc compiler. If original compiler
1428 is not available, use clang instead by default.

Mark Dickinsondbbed042011-09-19 16:38:08 +01001779- Issue #12973: Fix overflow checks that invoked undefined behaviour in
1780 int.__pow__. These overflow checks were causing int.__pow__ to produce
1781 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +01001782 compiler optimizing the check away. Also fix similar overflow checks
1783 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
1784 bugs caused test failures with recent versions of Clang.

Florent Xiclunac2279652012-02-12 14:49:03 +01001852- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01001853 has left two versions of customize_compiler, the original in
1854 distutils.sysconfig and another copy in distutils.ccompiler, with some

1857 is the case in 3.x.

Ned Deily0d0ea482012-02-10 12:59:06 +01001859- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1860 Distutils-based packages with C extension modules may fail because
1861 Apple has removed gcc-4.2, the version used to build python.org
1862 64-bit/32-bit Pythons. If the user does not explicitly override
1863 the default C compiler by setting the CC environment variable,
1864 Distutils will now attempt to compile extension modules with clang
1865 if gcc-4.2 is required but not found. Also as a convenience, if
1866 the user does explicitly set CC, substitute its value as the default
1867 compiler in the Distutils LDSHARED configuration variable for OS X.
1868 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1869 SDK, neither of which are available in Xcode 4. This change does not
1870 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07002120- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2121 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2122 interpreter process. This could cause failures in non-Distutils subprocesses
2123 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002124 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002125 deployment target only in the environment of each build subprocess. It is
2126 still possible to globally override the default by setting
2127 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2128 greater or equal to the default value, the value with which the interpreter
2129 was built.

2158 updating the check interval, so if the user decreases the check interval,
2159 the ticker doesn't have to wind down to zero from the old starting point
2160 before the new interval takes effect. And if the user increases the
2161 interval, it makes sure the new limit takes effect right away rather have an
2162 early task switch before recognizing the new interval.

Raymond Hettinger20397532010-09-12 02:11:45 +00003142- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
3143 This prevents user-created self-referencing ordered dictionaries from
3144 becoming permanently uncollectable GC garbage. The downside is that
3145 removing __del__ means that the internal doubly-linked list has to wait for
3146 GC collection rather than freeing memory immediately when the refcnt drops
3147 to zero.

3156 original error is re-raised.

3604
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003605- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3606 start byte and the continuation byte(s) are now considered invalid, instead
3607 of the number of bytes specified by the start byte.
3608 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3609 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3610 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
3611 Previous versions returned a single u'\ufffd'.

3615 arises from the "Overriding __eq__ blocks inheritance ..." warning
3616 when turned into an exception: in this case the exception simply
3617 gets ignored.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00003619- Issue #8748: Fix two issues with comparisons between complex and integer
3620 objects. (1) The comparison could incorrectly return True in some cases
3621 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
3622 (2) The comparison raised an OverflowError for large integers, leading
3623 to unpredictable exceptions when combining integers and complex objects
3624 in sets or dicts.
3625
Mark Dickinson81336372010-05-30 12:12:25 +00003626- Issue #5211: Implicit coercion for the complex type is now completely
3627 removed. (Coercion for arithmetic operations was already removed in 2.7

Georg Brandlba83f822010-03-14 09:50:54 +00004504 file position when calling `truncate()`. It would previously change the file
4505 position to the given argument, which goes against the tradition of

4509 class used to represent files stored inside an archive. The new
4510 implementation is significantly faster and can be wrapped in a

4512 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

4601-----------------
4602
Georg Brandlba83f822010-03-14 09:50:54 +00004603- The ``__complex__()`` method is now looked up on the class of instances to
4604 make it consistent with other special methods.

4608
Mark Dickinson1b34d252010-01-01 17:27:30 +00004609- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004610 DeprecationWarning when passed a float argument where an integer was expected.
4611 These functions and methods now raise TypeError instead. The majority of the
4612 effects of this change are in the extension modules, but some core functions
4613 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4614 and many unicode/str methods.

4628 of integers: the result of a/b is now correctly rounded for ints a and b (at
4629 least on IEEE 754 platforms), and in particular does not depend on the
4630 internal representation of a long.

4638
Georg Brandlba83f822010-03-14 09:50:54 +00004639 These executables now work properly with the arch(1) command: ``arch -ppc

4726 ``PyArg_ParseTupleAndKeywords()``, ``PyArg_VaParse()``,
4727 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept
4728 float arguments for integer format codes (other than 'L'): previously an
4729 attempt to pass a float resulted in a DeprecationWarning; now it gives a
4730 TypeError. For the 'L' format code (which previously had no warning) there is
4731 now a DeprecationWarning.

4780 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00004781

4783 1e50 in absolute value.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00004795
Georg Brandlba83f822010-03-14 09:50:54 +00004796- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4797 decimal string that's guaranteed to round back to x under correct rounding
4798 (with round-half-to-even rounding mode). Previously it gave a string based on
4799 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4800 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4801 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004802
Georg Brandlba83f822010-03-14 09:50:54 +00004803- Issue #7117: On almost all platforms: float-to-string and string-to-float
4804 conversions within Python are now correctly rounded. Places these conversions
4805 occur include: str for floats and complex numbers; the float and complex
4806 constructors; old-style and new-style numeric formatting; serialization and
4807 deserialization of floats and complex numbers using marshal, pickle and json;
4808 parsing of float and imaginary literals in Python code; Decimal-to-float
4809 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004810
Georg Brandlba83f822010-03-14 09:50:54 +00004811 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4812 providing correctly-rounded strtod and dtoa C functions. This code is
4813 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4814 the C compiler. There may be a small number of platforms on which correct
4815 operation of this code cannot be guaranteed, so the code is not used: notably,
4816 this applies to platforms where the C double format is not IEEE 754 binary64,
4817 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4818 and Python's configure script is unable to determine how to change the FPU
4819 precision. On these platforms conversions use the platform strtod and dtoa,
4820 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004821
Georg Brandlba83f822010-03-14 09:50:54 +00004822- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4823 uses the correctly-rounded string <-> float conversions described above (when
4824 available), and so produces correctly rounded results that will display nicely
4825 under the float repr. There are two related small changes: (1) round now
4826 accepts any class with an ``__index__()`` method for its second argument (but
4827 no longer accepts floats for the second argument), and (2) an excessively
4828 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4829 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00004959- Issue #5829: complex("1e500") no longer raises OverflowError. This makes it
4960 consistent with float("1e500") and interpretation of real and imaginary

Mark Dickinsonb1d45852009-05-11 15:33:08 +00004970- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
Mark Dickinsonb1d45852009-05-11 15:33:08 +00004971
Georg Brandlba83f822010-03-14 09:50:54 +00004972 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
4973 (2) parsing of strings representing infinities and nans was locale aware; and
4974 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00004976- Issue #5920: For ``float.__format__()``, change the behavior with the empty
4977 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
4978 but with at least one decimal point and with a default precision
4979 of 12. Previously, the behavior the same but with a default precision of 6.
4980 This more closely matches ``str()``, and reduces surprises when adding
4981 alignment flags to the empty presentation type. This also affects the new
4982 complex.__format__ in the same way.
4983
4984- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
4985 classtype's, even if it was None. property now inserts the __doc__ into the

Georg Brandlba83f822010-03-14 09:50:54 +00005047 untrackable objects are not tracked by the garbage collector. This can reduce
5048 the size of collections and therefore the garbage collection overhead on

5056 internal representation of integers, for performance reasons. Base 2**30 is
5057 enabled by default on 64-bit machines. Add --enable-big-digits option to

Georg Brandlba83f822010-03-14 09:50:54 +00005206- On windows, ``os.chdir()`` given unicode was not working if

5208 this code path is really executed because I cannot move to such directory on
5209 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00005211- Issue #4069: When ``set.remove(element)`` is used with a set element, the
5212 element is temporarily replaced with an equivalent frozenset. But the
5213 eventual KeyError would always report the empty ``frozenset()`` as the missing
5214 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00005234- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
5235 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5236 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5237 of using the replace error handler in PyUnicode_DecodeUTF8().
5238
Walter Dörwald726ba8e2009-05-06 14:32:35 +00005239- Issue #3739: The unicode-internal encoder now reports the number of characters

5241
Georg Brandlba83f822010-03-14 09:50:54 +00005242- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
5243 allocator will be automatically disabled when running under Valgrind. This
5244 gives improved memory leak detection when running under Valgrind, while taking
5245 advantage of pymalloc at other times.

6415 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
6416 neither __int__ nor __long__, TypeError used to be raised (with a

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00006613- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
6614
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006615- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6616 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6617 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6618 ``printf`` function, whereas PyString_FromFormat has an independent
6619 implementation and uses "%zd" on all platforms for size_t values.
6620 This makes a difference on win64, where ``printf`` needs "%Id" to display
6621 64bit values.
6622
Benjamin Peterson97179b02008-09-09 20:55:01 +00006623- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

6625
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00006626- Issue #3777: long() applied to a float object now always return a long
6627 object; previously an int would be returned for small values. the __long__
6628 method is allowed to return either an int or a long, but the behaviour of
6629 float objects should not change to respect backward compatibility.
6630
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00006631- Issue #3751: str.rpartition would perform a left-partition when called with
6632 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +00006637 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006638 was correctly parsed but parsing of subsequent arguments failed.
6639
Vinay Sajip35e3b032008-09-01 14:33:59 +00006640- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006641 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6642 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6643 when given a tuple of classes as second argument, were looking up
6644 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6645 type object.
6646
Neal Norwitz18aa3882008-08-24 05:04:52 +00006647- Fix crashes on memory allocation failure found with failmalloc.

Brett Cannon1eaf0742008-09-02 01:25:16 +00006716 warnings.catch_warnings() along with some API cleanup. Expanding the tests
6717 for catch_warnings() also led to an improvement in the raising of a

6790-----------------
6791
Guido van Rossumf8402962008-08-20 15:01:50 +00006792- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6793 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6794 extensions do not automatically benefit from the class attribute
6795 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6796 to their tp_flags field if they care. This is a backwards
6797 compatibility feature; in 3.0, all types will use the cache by
6798 default.
6799
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006800- Keyword arguments can now follow starred arguments. (``f(a, *args,
6801 keyword=23)`` is now valid syntax.)
6802
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006803- ctypes function pointers that are COM methods have a boolean True
6804 value again.
6805
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006806- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6807 by denying s# to parse objects that have a releasebuffer procedure,
6808 and introducing s*.
6809
Georg Brandl1e13ea92008-08-11 09:07:59 +00006810- Issue #3537: Fix an assertion failure when an empty but presized dict
6811 object was stored in the freelist.
6812
Mark Dickinsonb6467572008-08-04 21:30:09 +00006813- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6814 ValueError consistently across platforms.
6815
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006816- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6817 (64bit Unix, for example), unichr() would truncate its argument and return
6818 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6819
Neal Norwitze7d8be82008-07-31 17:17:14 +00006820- Apply security patches from Apple.
6821
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006822- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6823 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6824
Antoine Pitrou92f82162008-07-25 22:22:08 +00006825- Issue #1819: function calls with several named parameters are now on
6826 average 35% faster (as measured by pybench).
6827
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006828- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6829 the python debugger steps into a class statement: the free variables (local
6830 variables defined in an outer scope) would be deleted from the outer scope.
6831
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006832- Issue #2620: Overflow checking when allocating or reallocating memory
6833 was not always being done properly in some python types and extension
6834 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6835 all been updated to perform better checks and places in the code that
6836 would previously leak memory on the error path when such an allocation
6837 failed have been fixed.

6843
Benjamin Petersone977ad42008-08-20 01:42:01 +00006844- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6845 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6846
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006847- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6848 version reported by these tools does not necessarily follow the python

6850
Nick Coghlanf70385a2008-08-18 12:42:46 +00006851- Issue #2235: Added Py3k warnings for types which will become unhashable
6852 under the stricter __hash__ inheritance rules in 3.0. Several types
6853 which did not meet the rules for hash invariants and were already
6854 unhashable in 3.0 have now been explicitly flagged as unhashable in
6855 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6856 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6857

6913 the reload() built-in has been removed.
6914

Antoine Pitroude781a42008-08-09 12:43:23 +00006927 asking for a specific length. This problem only affected files opened

6970 interaction with the tp_hash slot (added in 2.6b2) are now documented
6971
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00006972- Issue #643841: The language reference now provides more detailed
6973 coverage of the lookup process for special methods. The disclaimers
6974 regarding lack of coverage of new-style classes have also been
6975 removed, since the coverage is now fairly reasonable.

6979================================
6980
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006981*Release date: 17-Jul-2008*
6982
Raymond Hettingere3ae6552008-06-20 04:18:15 +00006983Core and Builtins
6984-----------------
6985
Georg Brandl3e483f62008-07-16 22:57:41 +00006986- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6987 its methods now allow for items objects that can be converted to
6988 an integer using operator.index().
6989
Mark Dickinson64b7e502008-07-16 09:40:03 +00006990- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6991 produced a ValueError instead of giving the correct float.
6992
Eric Smitha5fa5a22008-07-16 00:11:49 +00006993- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6994 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6995
Mark Dickinson7103aa42008-07-15 19:08:33 +00006996- Issue #3008: the float type has a new instance method 'float.hex'
6997 and a new class method 'float.fromhex' to convert floating-point
6998 numbers to and from hexadecimal strings, respectively.
6999
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007000- Issue #2235: __hash__ is once again inherited by default. To allow
7001 collections.Hashable to remain meaningful in the presence of the
7002 default hash implementation (object.__hash__), it is now possible
7003 to explicit block inheritance of hash by setting __hash__=None at
7004 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7005 level.
7006
Nick Coghlanb028f502008-07-13 14:52:36 +00007007- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7008 the parent module cannot be found while performing an absolute import.
7009 This means that an incorrectly defined __package__ attribute will
7010 now only prevent relative imports in that module rather than causing
7011 all imports from that module to fail.
7012
Nick Coghlan14ff9942008-07-08 14:21:42 +00007013- Issue #2517: Allow unicode messages in Exceptions again by correctly
7014 bypassing the instance dictionary when looking up __unicode__ on
7015 new-style classes.
7016
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00007017- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
7018 set to a custom object whose write() method happens to install
7019 another file in sys.stdout.
7020
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00007021- Issue #3088: Corrected a race condition in classes derived from
7022 threading.local: the first member set by a thread could be saved in
7023 another thread's dictionary.
7024
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007025- Issue #3004: Minor change to slice.indices(): the start and stop
7026 arguments are now treated identically, making the behaviour easier
7027 to describe and understand. For example, slice(None, -10,
7028 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7029 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7030 10, -1).
7031
Georg Brandl278fc502008-07-19 12:46:12 +00007032- Issue #3219: Calling a function with repeated keyword arguments,
7033 f(a=2, a=23), would not cause a syntax error. This was a regression
7034 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00007035
Georg Brandl278fc502008-07-19 12:46:12 +00007036- Issue #2862: Make int and float freelist management consistent with
7037 other freelists. Changes their CompactFreeList apis into
7038 ClearFreeList apis and calls them via gc.collect().

7044 api functions without holding the GIL, which could lead to a fatal
7045 error when they failed.
7046
Martin v. Löwisaabf4042008-08-02 07:20:25 +00007047- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007072- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
7073 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007074 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007075 content-length. The problem had been corrected in the 2.4 branch, but never
7076 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00007091- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

7093
Brett Cannon8bb8fa52008-07-02 01:57:08 +00007094- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

7481 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00007482 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007483
7484 This is controlled by the configure argument ``--with-universal-archs``:
7485
7486 - ``--with-universal-archs=all``: install 4-way universal
7487
7488 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7489
7490 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7491
7492 This option should be used in combination with ``--enable-universalsdk=``.
7493
7494 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00007543- Issue #1631171: Re-implement the 'warnings' module in C (the
7544 original Python code has been kept as backup). This will allow for
7545 using the 'warning's machinery in such places as the parser where
7546 use of pure Python code is not possible. Both the ``showarning()``
7547 and ``formatwarning()`` gain an optional 'line' argument which is
7548 not called by default for backwards-compatibility reasons. Setting
7549 ``warnings.showwarning()`` to an implementation that lacks support
7550 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007613- Issue #2550: The approach used by client/server code for obtaining
7614 ports to listen on in network-oriented tests has been refined in an
7615 effort to facilitate running multiple instances of the entire
7616 regression test suite in parallel without issue.
7617 test_support.bind_port() has been fixed such that it will always
7618 return a unique port -- which wasn't always the case with the
7619 previous implementation, especially if socket options had been set
7620 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7621 new implementation of bind_port() will actually raise an exception
7622 if it is passed an AF_INET/SOCK_STREAM socket with either the
7623 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7624 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7625 the socket it's been passed. This currently only applies to
7626 Windows. This option prevents any other sockets from binding to the
7627 host/port we've bound to, thus removing the possibility of the
7628 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7629 when a second SOCK_STREAM socket binds and accepts to a host/port
7630 that's already been bound by another socket. The optional preferred
7631 port parameter to bind_port() has been removed. Under no
7632 circumstances should tests be hard coding ports!
7633
7634 test_support.find_unused_port() has also been introduced, which will
7635 pass a temporary socket object to bind_port() in order to obtain an
7636 unused port. The temporary socket object is then closed and
7637 deleted, and the port is returned. This method should only be used
7638 for obtaining an unused port in order to pass to an external program
7639 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7640 a parameter to a server-oriented class that doesn't give you direct
7641 access to the underlying socket used.
7642
7643 Finally, test_support.HOST has been introduced, which should be used
7644 for the host argument of any relevant socket calls (i.e. bind and
7645 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007646
7647 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007648 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007649 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7650 test_asynchat and test_socket_ssl.
7651
Georg Brandl3ee81df2008-05-17 18:14:43 +00007652 It is now possible for multiple instances of the regression test
7653 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00007707- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00007708 \Uxxxxxxxx did not accept values outside the Basic Multilingual
7709 Plane. This affected raw unicode literals and the
7710 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
7711 this case, like normal unicode literals and the 'unicode-escape'
7712 codec.

7936 Python 2.6 builtins. The expected usage of the future_builtins
7937 module is:
7938 from future_builtins import hex, oct
7939
Eric Smith7ef40bf2008-02-20 23:34:22 +00007940- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7941 exponents for exponents with absolute value < 100. Follows C99
7942 standard. This is a change on Windows, which would use 3 digits.
7943 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7944 so that any alterations it does to the resulting string will be
7945 available in stringlib/formatter.h (for float.__format__).
7946
Eric Smith5a3c1352008-02-19 13:21:56 +00007947- Implemented PEP 3101, Advanced String Formatting. This adds a new
7948 builtin format(); a format() method for str and unicode; a
7949 __format__() method to object, str, unicode, int, long, float, and
7950 datetime; the class string.Formatter; and the C API
7951 PyObject_Format().
7952
Georg Brandl3ee81df2008-05-17 18:14:43 +00007953- Fixed several potential crashes, all caused by specially crafted
7954 __del__ methods exploiting objects in temporarily inconsistent
7955 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00007956
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007957- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00007958 prevent a possible crash: an Abstract Base Class would try to access
7959 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00007960

Georg Brandl3ee81df2008-05-17 18:14:43 +00007964- Clear all free lists during a gc.collect() of the highest generation
7965 in order to allow pymalloc to free more arenas. Python may give back
7966 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007967
Georg Brandl3ee81df2008-05-17 18:14:43 +00007968- Issue #2045: Fix an infinite recursion triggered when printing a
7969 subclass of collections.defaultdict, if its default_factory is set
7970 to a bound method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007998- Patch #1473257: generator objects gain a gi_code attribute. This is
7999 the same object as the func_code attribute of the function that
8000 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008001
Georg Brandl3ee81df2008-05-17 18:14:43 +00008002- Issue #1920: "while 0" statements were completely removed by the
8003 compiler, even in the presence of an "else" clause, which is
8004 supposed to be run when the condition is false. Now the compiler
8005 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008006
Guido van Rossumeead05f2008-01-24 18:21:02 +00008007- A few crashers fixed: weakref_in_del.py (issue #1377858);
8008 loosing_dict_ref.py (issue #1303614, test67.py);
8009 borrowed_ref_[34].py (not in tracker).
8010
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00008011- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00008012 suppressed while an extension is loaded by calling SetErrorMode in

8014
Georg Brandl3ee81df2008-05-17 18:14:43 +00008015- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00008016 several extension methods and modules do not work without unicode
8017 support.
8018
Georg Brandl26543b12008-01-21 18:36:51 +00008019- Issue #1882: when compiling code from a string, encoding cookies in the

8023
Georg Brandl6caad7d2008-01-26 14:19:22 +00008024- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008025 added.
8026
Christian Heimesc94e2b52008-01-14 04:13:37 +00008027- sys.float_info / PyFloat_GetInfo: The floating point information
8028 object was converted from a dict to a specialized structseq object.
8029
Georg Brandl3ee81df2008-05-17 18:14:43 +00008030- Patch #1816: Added sys.flags structseq. It exposes the status of
8031 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008032
Georg Brandl3ee81df2008-05-17 18:14:43 +00008033- Objects/structseq.c: Implemented new structseq representation. The
8034 patch makes structseqs (e.g. the return value of os.stat) more
8035 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00008036
Georg Brandl3ee81df2008-05-17 18:14:43 +00008037- Patch #1700288: added a type attribute cache that caches method
8038 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00008039
Neal Norwitz3fc15b82008-01-10 05:42:58 +00008040- Bug #1776: __import__() no longer accepts filenames on any platform.

8046 envvar and sys.dont_write_bytecode attribute. All these can be set
8047 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00008048
Georg Brandl3ee81df2008-05-17 18:14:43 +00008049- Improve some exception messages when Windows fails to load an
8050 extension module. Now we get for example '%1 is not a valid Win32
8051 application' instead of 'error code 193'.

8108
Georg Brandl21e99f42010-03-07 15:23:59 +00008109- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008110 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8111 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008112
Georg Brandl3ee81df2008-05-17 18:14:43 +00008113- Issue #1686386: Tuple's tp_repr did not take into account the
8114 possibility of having a self-referential tuple, which is possible
8115 from C code. Nor did object's tp_str consider that a type's tp_str
8116 could do something that could lead to an inifinite recursion.
8117 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8118 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008119
Georg Brandl3ee81df2008-05-17 18:14:43 +00008120- Issue #1164: It was possible to trigger deadlock when using the
8121 'print' statement to write to a file since the GIL was not released
8122 as needed. Now PyObject_Print() does the right thing along with
8123 various tp_print implementations of the built-in types and those in
8124 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00008125

Georg Brandl3ee81df2008-05-17 18:14:43 +00008134 PyObject_Call() never calling back out to Python code to trigger
8135 recursion depth updates/checks. Required the creation of a static
8136 RuntimeError instance in case normalizing an exception put the
8137 recursion check value past its limit. Fixes crashers

Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008177- Request #1193128: str.translate() now allows a None argument for
8178 translations that only remove characters without re-mapping the
8179 remaining characters.
8180
Georg Brandl5cb76c12007-03-21 09:00:39 +00008181- Patch #1682205: a TypeError while unpacking an iterable is no longer
8182 masked by a generic one with the message "unpack non-sequence".

8185
Guido van Rossum143b5642007-03-23 04:58:42 +00008186- Bug #1683368: The object.__init__() and object.__new__() methods are
8187 now stricter in rejecting excess arguments. The only time when
8188 either allows excess arguments is when it is not overridden and the
8189 other one is. For backwards compatibility, when both are
8190 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008191 warning later). Also, type.__init__() insists on the same signature
8192 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00008194- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8195 object to complex using its __complex__() method before falling back
8196 to the __float__() method. Therefore, the functions in the cmath
8197 module now can operate on objects that define a __complex__()
8198 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00008216- Bug #1678647: write a newline after printing an exception in any
8217 case, even when converting the value to a string failed.
8218
Georg Brandl871f1bc2007-03-12 13:17:36 +00008219- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008220 its argument, if it exists. If not, it will work like before. This
8221 allows customizing the output of dir() in the presence of a
8222 __getattr__().

8232 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008233
Georg Brandlaa2321b2007-03-07 00:40:28 +00008234- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008235 makes the filenames the warning module prints much more sensible
8236 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00008237

Georg Brandl0fca97a2007-03-05 22:28:08 +00008249- Patch #1674228: when assigning a slice (old-style), check for the
8250 sq_ass_slice instead of the sq_slice slot.
8251
Georg Brandl3ee81df2008-05-17 18:14:43 +00008252- When printing an unraisable error, don't print exceptions. before

Neal Norwitzcbeb6872006-10-14 21:33:38 +00008303
Georg Brandl2c1375c2006-10-12 11:27:59 +00008304- Bug #1545497: when given an explicit base, int() did ignore NULs
8305 embedded in the string to convert.
8306
Georg Brandl846f73a2006-10-08 07:11:54 +00008307- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl4e933132006-09-06 20:05:58 +00008337- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.
8338 Also make sure that every exception class has __module__ set to

Neal Norwitzdac090d2006-09-05 03:53:08 +00008354- Bug #1520864: unpacking singleton tuples in list comprehensions and
Georg Brandl3ee81df2008-05-17 18:14:43 +00008355 generator expressions (x for x, in ... ) works again. Fixing this
8356 problem required changing the .pyc magic number. This means that
8357 .pyc files generated before 2.5c2 will be regenerated.

Guido van Rossum8bc09652008-02-21 18:18:37 +00008395- Removed uses of dict.has_key() from distutils, and uses of
8396 callable() from copy_reg.py, so the interpreter now starts up
8397 without warnings when '-3' is given. More work like this needs to

Georg Brandl3ee81df2008-05-17 18:14:43 +00009153- The implementation of UnicodeError objects has been simplified
9154 (start and end attributes are now stored directly as Py_ssize_t
9155 members).

Georg Brandl3ee81df2008-05-17 18:14:43 +00009157- Issue #829951: In the smtplib module, SMTP.starttls() now complies
9158 with RFC 3207 and forgets any knowledge obtained from the server not
9159 obtained from the TLS negotiation itself. Patch contributed by Bill
9160 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00009161
Georg Brandl3ee81df2008-05-17 18:14:43 +00009162- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00009163 that the SMTP.starttls() caller no longer needs to call ehlo()
9164 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00009165 does not claim to support starttls. Adds the
9166 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
9167 Fenner.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009209- Patch #976880: ``mmap`` objects now have an ``rfind`` method that
Andrew M. Kuchling5c60bfc2008-01-19 18:18:41 +00009210 works as expected. ``mmap.find`` also takes an optional ``end``
9211 parameter.
9212
Georg Brandl3ee81df2008-05-17 18:14:43 +00009213- _winreg's HKEY object has gained __enter__ and __exit__ methods to

9236 contents before adding elements from the iterable. This fix brings
9237 the behavior into line with that for list.__init__().
Raymond Hettingeradf9ffd2007-12-13 00:08:37 +00009238
Georg Brandl3ee81df2008-05-17 18:14:43 +00009239- Added wide char functions to msvcrt module: getwch, getwche, putwch

9245
Georg Brandl3ee81df2008-05-17 18:14:43 +00009246- Marshal.dumps() now expects exact type matches for int, long, float,
9247 complex, tuple, list, dict, set, and frozenset. Formerly, it would
9248 silently miscode subclasses of those types. Now, it raises a
9249 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00009250

Georg Brandl3ee81df2008-05-17 18:14:43 +00009265 time so that opening a database previously created with the DB_DUP
9266 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9267 opens. Specifically: dictionary assignment to a DB object will
9268 replace all values for a given key when the database allows
9269 duplicate values. DB users should use DB.put(k, v) when they want
9270 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009271

9277 characters with ASCII value less than 32. Also, it correctly quotes
9278 dots only if they occur on a single line, as opposed to the previous
9279 behavior of quoting dots if they are the second character of any
9280 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00009281

9310 negative numbers, per the underlying C implementation.
Guido van Rossumbb2cc692007-01-14 17:03:32 +00009311

Georg Brandl3ee81df2008-05-17 18:14:43 +00009689- Removed the macfs module. It had been deprecated since Python 2.5.
9690 This lead to the deprecation of macostools.touched() as it relied
9691 solely on macfs and was a no-op under OS X.
