22 is modified during the lifetime of the Python process after zipimport has
23 already cached the zip's table of contents we detect this and recover
24 rather than read bad data from the .zip (causing odd import errors).
25

36 contains a frame, and the frame kept a reference to the Python state of the
37 destroyed C thread. The crash occurs when a trace function is setup.

1674 32-bit-only installer Pythons on systems with Xcode 4 (currently
1675 OS X 10.8, 10.7, and optionally 10.6).
1676 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1677 * Since Xcode 4 removes ppc support, extension module builds now
1678 check for ppc compiler support and by default remove ppc and
1679 ppc64 archs when they are not available.
1680 * Extension module builds now revert to using system installed
1681 headers and libs (/usr and /System/Library) if the SDK used
1682 to build the interpreter is not installed or has moved.
1683 * Try to avoid building extension modules with deprecated
1684 and problematic Apple llvm-gcc compiler. If original compiler
1685 is not available, use clang instead by default.

Mark Dickinsona96b0d12011-09-24 09:01:16 +01002039 compiler optimizing the check away. Also fix similar overflow checks
2040 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
2041 bugs caused test failures with recent versions of Clang.

Florent Xiclunac2279652012-02-12 14:49:03 +01002109- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01002110 has left two versions of customize_compiler, the original in
2111 distutils.sysconfig and another copy in distutils.ccompiler, with some

Ned Deily0d0ea482012-02-10 12:59:06 +01002116- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
2117 Distutils-based packages with C extension modules may fail because
2118 Apple has removed gcc-4.2, the version used to build python.org
2119 64-bit/32-bit Pythons. If the user does not explicitly override
2120 the default C compiler by setting the CC environment variable,
2121 Distutils will now attempt to compile extension modules with clang
2122 if gcc-4.2 is required but not found. Also as a convenience, if
2123 the user does explicitly set CC, substitute its value as the default
2124 compiler in the Distutils LDSHARED configuration variable for OS X.
2125 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2126 SDK, neither of which are available in Xcode 4. This change does not
2127 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07002377- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2378 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2379 interpreter process. This could cause failures in non-Distutils subprocesses
2380 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002381 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002382 deployment target only in the environment of each build subprocess. It is
2383 still possible to globally override the default by setting
2384 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2385 greater or equal to the default value, the value with which the interpreter
2386 was built.

2416 the ticker doesn't have to wind down to zero from the old starting point
2417 before the new interval takes effect. And if the user increases the
2418 interval, it makes sure the new limit takes effect right away rather have an
2419 early task switch before recognizing the new interval.

3398
Raymond Hettinger20397532010-09-12 02:11:45 +00003399- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
3400 This prevents user-created self-referencing ordered dictionaries from
3401 becoming permanently uncollectable GC garbage. The downside is that
3402 removing __del__ means that the internal doubly-linked list has to wait for
3403 GC collection rather than freeing memory immediately when the refcnt drops
3404 to zero.
3405

3409
Antoine Pitrouc818ed42010-09-07 21:40:25 +00003410- Issue #9792: In case of connection failure, socket.create_connection()

3412 to fetch the original errno, or to filter timeout errors. Now the
3413 original error is re-raised.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003862- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3863 start byte and the continuation byte(s) are now considered invalid, instead
3864 of the number of bytes specified by the start byte.
3865 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3866 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3867 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
3868 Previous versions returned a single u'\ufffd'.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00003876- Issue #8748: Fix two issues with comparisons between complex and integer
3877 objects. (1) The comparison could incorrectly return True in some cases
3878 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
3879 (2) The comparison raised an OverflowError for large integers, leading

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004760- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00004761 file position when calling `truncate()`. It would previously change the file
4762 position to the given argument, which goes against the tradition of

4766 class used to represent files stored inside an archive. The new
4767 implementation is significantly faster and can be wrapped in a
4768 ``io.BufferedReader`` object for more speedups. It also solves an issue
4769 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

4858-----------------
4859
Georg Brandlba83f822010-03-14 09:50:54 +00004860- The ``__complex__()`` method is now looked up on the class of instances to
4861 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00004863- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
4864 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
4865
Mark Dickinson1b34d252010-01-01 17:27:30 +00004866- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004867 DeprecationWarning when passed a float argument where an integer was expected.
4868 These functions and methods now raise TypeError instead. The majority of the
4869 effects of this change are in the extension modules, but some core functions
4870 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4871 and many unicode/str methods.

4885 of integers: the result of a/b is now correctly rounded for ints a and b (at
4886 least on IEEE 754 platforms), and in particular does not depend on the
4887 internal representation of a long.

4895
Georg Brandlba83f822010-03-14 09:50:54 +00004896 These executables now work properly with the arch(1) command: ``arch -ppc
4897 python`` will start a universal binary version of python in PPC mode (unlike

4983 ``PyArg_ParseTupleAndKeywords()``, ``PyArg_VaParse()``,
4984 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept
4985 float arguments for integer format codes (other than 'L'): previously an
4986 attempt to pass a float resulted in a DeprecationWarning; now it gives a
4987 TypeError. For the 'L' format code (which previously had no warning) there is
4988 now a DeprecationWarning.

5036 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
5037 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00005038
Georg Brandlba83f822010-03-14 09:50:54 +00005039- Remove switch from "%f" formatting to "%g" formatting for floats larger than
5040 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00005041
Georg Brandlba83f822010-03-14 09:50:54 +00005042- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
5043 1e-100 used to raise OverflowError, but now gives the requested 120
5044 significant digits instead.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00005052
Georg Brandlba83f822010-03-14 09:50:54 +00005053- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
5054 decimal string that's guaranteed to round back to x under correct rounding
5055 (with round-half-to-even rounding mode). Previously it gave a string based on
5056 rounding x to 17 decimal digits. repr(x) for a complex number behaves
5057 similarly. On platforms where the correctly-rounded strtod and dtoa code is
5058 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005059
Georg Brandlba83f822010-03-14 09:50:54 +00005060- Issue #7117: On almost all platforms: float-to-string and string-to-float
5061 conversions within Python are now correctly rounded. Places these conversions
5062 occur include: str for floats and complex numbers; the float and complex
5063 constructors; old-style and new-style numeric formatting; serialization and
5064 deserialization of floats and complex numbers using marshal, pickle and json;
5065 parsing of float and imaginary literals in Python code; Decimal-to-float
5066 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005067
Georg Brandlba83f822010-03-14 09:50:54 +00005068 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
5069 providing correctly-rounded strtod and dtoa C functions. This code is
5070 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5071 the C compiler. There may be a small number of platforms on which correct
5072 operation of this code cannot be guaranteed, so the code is not used: notably,
5073 this applies to platforms where the C double format is not IEEE 754 binary64,
5074 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
5075 and Python's configure script is unable to determine how to change the FPU
5076 precision. On these platforms conversions use the platform strtod and dtoa,
5077 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005078
Georg Brandlba83f822010-03-14 09:50:54 +00005079- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5080 uses the correctly-rounded string <-> float conversions described above (when
5081 available), and so produces correctly rounded results that will display nicely
5082 under the float repr. There are two related small changes: (1) round now
5083 accepts any class with an ``__index__()`` method for its second argument (but
5084 no longer accepts floats for the second argument), and (2) an excessively
5085 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
5086 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00005228
Georg Brandlba83f822010-03-14 09:50:54 +00005229 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
5230 (2) parsing of strings representing infinities and nans was locale aware; and
5231 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00005233- Issue #5920: For ``float.__format__()``, change the behavior with the empty
5234 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
5235 but with at least one decimal point and with a default precision
5236 of 12. Previously, the behavior the same but with a default precision of 6.
5237 This more closely matches ``str()``, and reduces surprises when adding
5238 alignment flags to the empty presentation type. This also affects the new
5239 complex.__format__ in the same way.
5240
5241- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

5465 this code path is really executed because I cannot move to such directory on

5470 eventual KeyError would always report the empty ``frozenset()`` as the missing

5492 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

Mark Dickinson5fd3af22009-07-07 15:08:28 +00006661
Georg Brandlba83f822010-03-14 09:50:54 +00006662- Issues #1530559, #1741130: Fix various struct.pack inconsistencies for the

Georg Brandlba83f822010-03-14 09:50:54 +00006666 - Packing a float now always gives a Deprecation Warning. Previously it
6667 only warned for 'I', 'L', '*B', '*H', '*I', '*L'.
Mark Dickinson463dc4b2009-07-05 10:01:24 +00006668
Georg Brandlba83f822010-03-14 09:50:54 +00006669 - If x is not an int, long or float, then packing x will always result in
6670 struct.error. Previously an x with an __int__ method could be packed by
6671 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
6672 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
6673 neither __int__ nor __long__, TypeError used to be raised (with a
6674 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
6675 struct.error in other cases.
Mark Dickinson463dc4b2009-07-05 10:01:24 +00006676
Georg Brandlba83f822010-03-14 09:50:54 +00006677 Note: as of Python 2.7 beta 1, the above is out of date. In 2.7 beta 1, any
6678 argument with an __int__ method can be packed, but use of this feature
6679 triggers a DeprecationWarning.

Antoine Pitrou59c44f32009-10-30 17:07:08 +00006727- Issue #7222: Make thread "reaping" more reliable so that reference
Georg Brandlba83f822010-03-14 09:50:54 +00006728 leak-chasing test runs give sensible results. The previous method of reaping
6729 threads could return successfully while some Thread objects were still
6730 referenced. This also introduces a new private function: ``thread._count()``.
Antoine Pitrou59c44f32009-10-30 17:07:08 +00006731
Georg Brandlba83f822010-03-14 09:50:54 +00006732- Issue #7151: Fixed regrtest -j so that output to stderr from a test no longer
6733 runs the risk of causing the worker thread to fail.
R. David Murray282396f2009-10-18 21:12:37 +00006734
Antoine Pitrou58d2f262009-10-10 20:52:11 +00006735- Issue #7055: test___all__ now greedily detects all modules which have an

R. David Murray14dcd432009-10-14 13:58:07 +00006738- Issue #7058: Added save/restore for things like sys.argv and cwd to
6739 runtest_inner in regrtest, with warnings if the called test modifies them,
6740 and a new section in the summary report at the end.

Guilherme Polo7f146ab2009-06-21 17:22:50 +00006747- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
6748 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00006749 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
6750 the tests if DISPLAY is defined but can't be used.

6754
Georg Brandlba83f822010-03-14 09:50:54 +00006755- Issue #5354: New test support function import_fresh_module() makes it easy to
6756 import both normal and optimised versions of modules. test_heapq and
6757 test_warnings have been adjusted to use it, tests for other modules with both
6758 C and Python implementations in the stdlib can be adjusted to use it over
6759 time.

6769 support, which does the conversion.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00006870- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
6871
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006872- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6873 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6874 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6875 ``printf`` function, whereas PyString_FromFormat has an independent
6876 implementation and uses "%zd" on all platforms for size_t values.
6877 This makes a difference on win64, where ``printf`` needs "%Id" to display
6878 64bit values.
6879
Benjamin Peterson97179b02008-09-09 20:55:01 +00006880- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
6881 error.
6882
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00006883- Issue #3777: long() applied to a float object now always return a long
6884 object; previously an int would be returned for small values. the __long__
6885 method is allowed to return either an int or a long, but the behaviour of
6886 float objects should not change to respect backward compatibility.
6887
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00006888- Issue #3751: str.rpartition would perform a left-partition when called with
6889 a unicode argument.
6890
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00006891- Issue #3683: Fix compilation when --without-threads is given.

Vinay Sajip35e3b032008-09-01 14:33:59 +00006894 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006895 was correctly parsed but parsing of subsequent arguments failed.
6896
Vinay Sajip35e3b032008-09-01 14:33:59 +00006897- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006898 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6899 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6900 when given a tuple of classes as second argument, were looking up
6901 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6902 type object.
6903
Neal Norwitz18aa3882008-08-24 05:04:52 +00006904- Fix crashes on memory allocation failure found with failmalloc.

Brett Cannon1eaf0742008-09-02 01:25:16 +00006973 warnings.catch_warnings() along with some API cleanup. Expanding the tests
6974 for catch_warnings() also led to an improvement in the raising of a
6975 DeprecationWarning related to warnings.warn_explicit().
6976

7047-----------------
7048
Guido van Rossumf8402962008-08-20 15:01:50 +00007049- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
7050 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
7051 extensions do not automatically benefit from the class attribute
7052 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
7053 to their tp_flags field if they care. This is a backwards
7054 compatibility feature; in 3.0, all types will use the cache by
7055 default.
7056
Benjamin Petersonf647dc12008-08-20 01:27:30 +00007057- Keyword arguments can now follow starred arguments. (``f(a, *args,
7058 keyword=23)`` is now valid syntax.)
7059
Thomas Heller0ad5ae02008-08-19 19:25:04 +00007060- ctypes function pointers that are COM methods have a boolean True
7061 value again.
7062
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00007063- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
7064 by denying s# to parse objects that have a releasebuffer procedure,
7065 and introducing s*.
7066
Georg Brandl1e13ea92008-08-11 09:07:59 +00007067- Issue #3537: Fix an assertion failure when an empty but presized dict
7068 object was stored in the freelist.
7069
Mark Dickinsonb6467572008-08-04 21:30:09 +00007070- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
7071 ValueError consistently across platforms.
7072
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00007073- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
7074 (64bit Unix, for example), unichr() would truncate its argument and return
7075 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
7076
Neal Norwitze7d8be82008-07-31 17:17:14 +00007077- Apply security patches from Apple.
7078
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00007079- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
7080 PyErr_ExceptionMatches returns 0 when an exception occurs there.
7081
Antoine Pitrou92f82162008-07-25 22:22:08 +00007082- Issue #1819: function calls with several named parameters are now on
7083 average 35% faster (as measured by pybench).
7084
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00007085- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
7086 the python debugger steps into a class statement: the free variables (local
7087 variables defined in an outer scope) would be deleted from the outer scope.
7088
Gregory P. Smith0470bab2008-07-22 04:46:32 +00007089- Issue #2620: Overflow checking when allocating or reallocating memory
7090 was not always being done properly in some python types and extension
7091 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
7092 all been updated to perform better checks and places in the code that
7093 would previously leak memory on the error path when such an allocation
7094 failed have been fixed.

7098
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00007099- Issue #3612: Added some missing basic types in ctypes.wintypes.
7100
Benjamin Petersone977ad42008-08-20 01:42:01 +00007101- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
7102 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
7103
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00007104- Issue #2234: distutils failed for some versions of the cygwin compiler. The
7105 version reported by these tools does not necessarily follow the python
7106 version numbering scheme, so the module is less strict when parsing it.
7107
Nick Coghlanf70385a2008-08-18 12:42:46 +00007108- Issue #2235: Added Py3k warnings for types which will become unhashable
7109 under the stricter __hash__ inheritance rules in 3.0. Several types
7110 which did not meet the rules for hash invariants and were already
7111 unhashable in 3.0 have now been explicitly flagged as unhashable in
7112 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
7113 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
7114
Brett Cannon88f801d2008-08-18 00:46:22 +00007115- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

7242
Georg Brandl3e483f62008-07-16 22:57:41 +00007243- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7244 its methods now allow for items objects that can be converted to
7245 an integer using operator.index().
7246
Mark Dickinson64b7e502008-07-16 09:40:03 +00007247- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7248 produced a ValueError instead of giving the correct float.
7249
Eric Smitha5fa5a22008-07-16 00:11:49 +00007250- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
7251 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
7252
Mark Dickinson7103aa42008-07-15 19:08:33 +00007253- Issue #3008: the float type has a new instance method 'float.hex'
7254 and a new class method 'float.fromhex' to convert floating-point
7255 numbers to and from hexadecimal strings, respectively.
7256
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007257- Issue #2235: __hash__ is once again inherited by default. To allow
7258 collections.Hashable to remain meaningful in the presence of the
7259 default hash implementation (object.__hash__), it is now possible
7260 to explicit block inheritance of hash by setting __hash__=None at
7261 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7262 level.
7263
Nick Coghlanb028f502008-07-13 14:52:36 +00007264- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7265 the parent module cannot be found while performing an absolute import.
7266 This means that an incorrectly defined __package__ attribute will
7267 now only prevent relative imports in that module rather than causing
7268 all imports from that module to fail.
7269
Nick Coghlan14ff9942008-07-08 14:21:42 +00007270- Issue #2517: Allow unicode messages in Exceptions again by correctly

7280 another thread's dictionary.
7281
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007282- Issue #3004: Minor change to slice.indices(): the start and stop
7283 arguments are now treated identically, making the behaviour easier
7284 to describe and understand. For example, slice(None, -10,
7285 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7286 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7287 10, -1).

Georg Brandl278fc502008-07-19 12:46:12 +00007289- Issue #3219: Calling a function with repeated keyword arguments,

7330 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007331 wrong because the actual transmitted size could differ from the

7738 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00007739 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007740
7741 This is controlled by the configure argument ``--with-universal-archs``:
7742
7743 - ``--with-universal-archs=all``: install 4-way universal
7744
7745 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7746
7747 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7748
7749 This option should be used in combination with ``--enable-universalsdk=``.
7750
7751 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 +00007800- Issue #1631171: Re-implement the 'warnings' module in C (the
7801 original Python code has been kept as backup). This will allow for
7802 using the 'warning's machinery in such places as the parser where
7803 use of pure Python code is not possible. Both the ``showarning()``
7804 and ``formatwarning()`` gain an optional 'line' argument which is
7805 not called by default for backwards-compatibility reasons. Setting
7806 ``warnings.showwarning()`` to an implementation that lacks support
7807 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007870- Issue #2550: The approach used by client/server code for obtaining
7871 ports to listen on in network-oriented tests has been refined in an
7872 effort to facilitate running multiple instances of the entire
7873 regression test suite in parallel without issue.
7874 test_support.bind_port() has been fixed such that it will always
7875 return a unique port -- which wasn't always the case with the
7876 previous implementation, especially if socket options had been set
7877 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7878 new implementation of bind_port() will actually raise an exception
7879 if it is passed an AF_INET/SOCK_STREAM socket with either the
7880 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7881 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7882 the socket it's been passed. This currently only applies to
7883 Windows. This option prevents any other sockets from binding to the
7884 host/port we've bound to, thus removing the possibility of the
7885 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7886 when a second SOCK_STREAM socket binds and accepts to a host/port
7887 that's already been bound by another socket. The optional preferred
7888 port parameter to bind_port() has been removed. Under no
7889 circumstances should tests be hard coding ports!
7890
7891 test_support.find_unused_port() has also been introduced, which will
7892 pass a temporary socket object to bind_port() in order to obtain an
7893 unused port. The temporary socket object is then closed and
7894 deleted, and the port is returned. This method should only be used
7895 for obtaining an unused port in order to pass to an external program
7896 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7897 a parameter to a server-oriented class that doesn't give you direct
7898 access to the underlying socket used.
7899
7900 Finally, test_support.HOST has been introduced, which should be used
7901 for the host argument of any relevant socket calls (i.e. bind and
7902 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007903
7904 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007905 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007906 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7907 test_asynchat and test_socket_ssl.
7908
Georg Brandl3ee81df2008-05-17 18:14:43 +00007909 It is now possible for multiple instances of the regression test
7910 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00007964- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00007965 \Uxxxxxxxx did not accept values outside the Basic Multilingual
7966 Plane. This affected raw unicode literals and the
7967 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
7968 this case, like normal unicode literals and the 'unicode-escape'
7969 codec.

Eric Smitha73fbe72008-02-23 03:09:44 +00008189- Added the future_builtins module, which contains hex() and oct().
8190 These are the PEP 3127 version of these functions, designed to be
8191 compatible with the hex() and oct() builtins from Python 3.0. They
8192 differ slightly in their output formats from the existing, unchanged
8193 Python 2.6 builtins. The expected usage of the future_builtins
8194 module is:
8195 from future_builtins import hex, oct
8196
Eric Smith7ef40bf2008-02-20 23:34:22 +00008197- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8198 exponents for exponents with absolute value < 100. Follows C99
8199 standard. This is a change on Windows, which would use 3 digits.
8200 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8201 so that any alterations it does to the resulting string will be
8202 available in stringlib/formatter.h (for float.__format__).
8203
Eric Smith5a3c1352008-02-19 13:21:56 +00008204- Implemented PEP 3101, Advanced String Formatting. This adds a new
8205 builtin format(); a format() method for str and unicode; a
8206 __format__() method to object, str, unicode, int, long, float, and
8207 datetime; the class string.Formatter; and the C API
8208 PyObject_Format().
8209
Georg Brandl3ee81df2008-05-17 18:14:43 +00008210- Fixed several potential crashes, all caused by specially crafted
8211 __del__ methods exploiting objects in temporarily inconsistent
8212 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00008213

Georg Brandl3ee81df2008-05-17 18:14:43 +00008221- Clear all free lists during a gc.collect() of the highest generation
8222 in order to allow pymalloc to free more arenas. Python may give back
8223 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008224
Georg Brandl3ee81df2008-05-17 18:14:43 +00008225- Issue #2045: Fix an infinite recursion triggered when printing a

Georg Brandl3ee81df2008-05-17 18:14:43 +00008255- Patch #1473257: generator objects gain a gi_code attribute. This is
8256 the same object as the func_code attribute of the function that
8257 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008258
Georg Brandl3ee81df2008-05-17 18:14:43 +00008259- Issue #1920: "while 0" statements were completely removed by the
8260 compiler, even in the presence of an "else" clause, which is
8261 supposed to be run when the condition is false. Now the compiler
8262 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008263
Guido van Rossumeead05f2008-01-24 18:21:02 +00008264- A few crashers fixed: weakref_in_del.py (issue #1377858);

8271
Georg Brandl3ee81df2008-05-17 18:14:43 +00008272- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00008273 several extension methods and modules do not work without unicode
8274 support.
8275

8280
Georg Brandl6caad7d2008-01-26 14:19:22 +00008281- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008282 added.
8283
Christian Heimesc94e2b52008-01-14 04:13:37 +00008284- sys.float_info / PyFloat_GetInfo: The floating point information
8285 object was converted from a dict to a specialized structseq object.
8286
Georg Brandl3ee81df2008-05-17 18:14:43 +00008287- Patch #1816: Added sys.flags structseq. It exposes the status of
8288 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008289
Georg Brandl3ee81df2008-05-17 18:14:43 +00008290- Objects/structseq.c: Implemented new structseq representation. The
8291 patch makes structseqs (e.g. the return value of os.stat) more
8292 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00008293
Georg Brandl3ee81df2008-05-17 18:14:43 +00008294- Patch #1700288: added a type attribute cache that caches method
8295 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00008296
Neal Norwitz3fc15b82008-01-10 05:42:58 +00008297- Bug #1776: __import__() no longer accepts filenames on any platform.

8303 envvar and sys.dont_write_bytecode attribute. All these can be set
8304 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00008305
Georg Brandl3ee81df2008-05-17 18:14:43 +00008306- Improve some exception messages when Windows fails to load an
8307 extension module. Now we get for example '%1 is not a valid Win32
8308 application' instead of 'error code 193'.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008367 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8368 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008369
Georg Brandl3ee81df2008-05-17 18:14:43 +00008370- Issue #1686386: Tuple's tp_repr did not take into account the
8371 possibility of having a self-referential tuple, which is possible
8372 from C code. Nor did object's tp_str consider that a type's tp_str
8373 could do something that could lead to an inifinite recursion.
8374 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8375 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008376

8378 'print' statement to write to a file since the GIL was not released
8379 as needed. Now PyObject_Print() does the right thing along with
8380 various tp_print implementations of the built-in types and those in
8381 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00008382

Georg Brandl3ee81df2008-05-17 18:14:43 +00008391 PyObject_Call() never calling back out to Python code to trigger
8392 recursion depth updates/checks. Required the creation of a static
8393 RuntimeError instance in case normalizing an exception put the
8394 recursion check value past its limit. Fixes crashers

Guido van Rossum143b5642007-03-23 04:58:42 +00008443- Bug #1683368: The object.__init__() and object.__new__() methods are
8444 now stricter in rejecting excess arguments. The only time when
8445 either allows excess arguments is when it is not overridden and the
8446 other one is. For backwards compatibility, when both are
8447 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008448 warning later). Also, type.__init__() insists on the same signature
8449 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00008451- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8452 object to complex using its __complex__() method before falling back
8453 to the __float__() method. Therefore, the functions in the cmath
8454 module now can operate on objects that define a __complex__()
8455 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00008473- Bug #1678647: write a newline after printing an exception in any
8474 case, even when converting the value to a string failed.
8475
Georg Brandl871f1bc2007-03-12 13:17:36 +00008476- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008477 its argument, if it exists. If not, it will work like before. This
8478 allows customizing the output of dir() in the presence of a
8479 __getattr__().

8489 raising a ValueError.

Georg Brandlaa2321b2007-03-07 00:40:28 +00008491- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008492 makes the filenames the warning module prints much more sensible
8493 when a PYTHONSTARTUP file is used.

8507 sq_ass_slice instead of the sq_slice slot.
8508
Georg Brandl3ee81df2008-05-17 18:14:43 +00008509- When printing an unraisable error, don't print exceptions. before

Georg Brandl2c1375c2006-10-12 11:27:59 +00008561- Bug #1545497: when given an explicit base, int() did ignore NULs
8562 embedded in the string to convert.
8563
Georg Brandl846f73a2006-10-08 07:11:54 +00008564- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00008612 generator expressions (x for x, in ... ) works again. Fixing this

9416 obtained from the TLS negotiation itself. Patch contributed by Bill
9417 Fenner.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009419- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00009420 that the SMTP.starttls() caller no longer needs to call ehlo()
9421 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00009422 does not claim to support starttls. Adds the
9423 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
9424 Fenner.

9504 complex, tuple, list, dict, set, and frozenset. Formerly, it would
9505 silently miscode subclasses of those types. Now, it raises a
9506 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00009507

Georg Brandl3ee81df2008-05-17 18:14:43 +00009522 time so that opening a database previously created with the DB_DUP
9523 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9524 opens. Specifically: dictionary assignment to a DB object will
9525 replace all values for a given key when the database allows
9526 duplicate values. DB users should use DB.put(k, v) when they want
9527 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009528

9534 characters with ASCII value less than 32. Also, it correctly quotes
9535 dots only if they occur on a single line, as opposed to the previous
9536 behavior of quoting dots if they are the second character of any
9537 line.
