1676 32-bit-only installer Pythons on systems with Xcode 4 (currently
1677 OS X 10.8, 10.7, and optionally 10.6).
1678 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1679 * Since Xcode 4 removes ppc support, extension module builds now
1680 check for ppc compiler support and by default remove ppc and
1681 ppc64 archs when they are not available.
1682 * Extension module builds now revert to using system installed
1683 headers and libs (/usr and /System/Library) if the SDK used
1684 to build the interpreter is not installed or has moved.
1685 * Try to avoid building extension modules with deprecated
1686 and problematic Apple llvm-gcc compiler. If original compiler
1687 is not available, use clang instead by default.

Mark Dickinsondbbed042011-09-19 16:38:08 +01002038- Issue #12973: Fix overflow checks that invoked undefined behaviour in
2039 int.__pow__. These overflow checks were causing int.__pow__ to produce
2040 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +01002041 compiler optimizing the check away. Also fix similar overflow checks
2042 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
2043 bugs caused test failures with recent versions of Clang.

Florent Xiclunac2279652012-02-12 14:49:03 +01002111- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01002112 has left two versions of customize_compiler, the original in
2113 distutils.sysconfig and another copy in distutils.ccompiler, with some

Ned Deily0d0ea482012-02-10 12:59:06 +01002118- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
2119 Distutils-based packages with C extension modules may fail because
2120 Apple has removed gcc-4.2, the version used to build python.org
2121 64-bit/32-bit Pythons. If the user does not explicitly override
2122 the default C compiler by setting the CC environment variable,
2123 Distutils will now attempt to compile extension modules with clang
2124 if gcc-4.2 is required but not found. Also as a convenience, if
2125 the user does explicitly set CC, substitute its value as the default
2126 compiler in the Distutils LDSHARED configuration variable for OS X.
2127 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2128 SDK, neither of which are available in Xcode 4. This change does not
2129 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07002379- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2380 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2381 interpreter process. This could cause failures in non-Distutils subprocesses
2382 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002383 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002384 deployment target only in the environment of each build subprocess. It is
2385 still possible to globally override the default by setting
2386 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2387 greater or equal to the default value, the value with which the interpreter
2388 was built.

2418 the ticker doesn't have to wind down to zero from the old starting point
2419 before the new interval takes effect. And if the user increases the

Mark Dickinsoncb61e5d2010-09-26 10:37:12 +00003246- Issue #9869: Make long() and PyNumber_Long return something of type
3247 long for a class whose __long__ method returns a plain int. This
3248 fixes an interpreter crash when initializing an instance of a long

Victor Stinnercaafd772010-09-08 10:51:01 +00003256- Issue #4947: The write() method of sys.stdout and sys.stderr uses their
3257 encoding and errors attributes instead of using utf-8 in strict mode, to get
3258 the same behaviour than the print statement.

3400
Raymond Hettinger20397532010-09-12 02:11:45 +00003401- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
3402 This prevents user-created self-referencing ordered dictionaries from
3403 becoming permanently uncollectable GC garbage. The downside is that
3404 removing __del__ means that the internal doubly-linked list has to wait for
3405 GC collection rather than freeing memory immediately when the refcnt drops
3406 to zero.
3407

3411
Antoine Pitrouc818ed42010-09-07 21:40:25 +00003412- Issue #9792: In case of connection failure, socket.create_connection()
3413 would swallow the exception and raise a new one, making it impossible
3414 to fetch the original errno, or to filter timeout errors. Now the
3415 original error is re-raised.

3863
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003864- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3865 start byte and the continuation byte(s) are now considered invalid, instead
3866 of the number of bytes specified by the start byte.
3867 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3868 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3869 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
3870 Previous versions returned a single u'\ufffd'.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00003878- Issue #8748: Fix two issues with comparisons between complex and integer
3879 objects. (1) The comparison could incorrectly return True in some cases
3880 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
3881 (2) The comparison raised an OverflowError for large integers, leading
3882 to unpredictable exceptions when combining integers and complex objects
3883 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +00003885- Issue #5211: Implicit coercion for the complex type is now completely

Georg Brandlba83f822010-03-14 09:50:54 +00004763 file position when calling `truncate()`. It would previously change the file
4764 position to the given argument, which goes against the tradition of

4768 class used to represent files stored inside an archive. The new
4769 implementation is significantly faster and can be wrapped in a
4770 ``io.BufferedReader`` object for more speedups. It also solves an issue
4771 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00004862- The ``__complex__()`` method is now looked up on the class of instances to
4863 make it consistent with other special methods.

4867
Mark Dickinson1b34d252010-01-01 17:27:30 +00004868- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004869 DeprecationWarning when passed a float argument where an integer was expected.
4870 These functions and methods now raise TypeError instead. The majority of the
4871 effects of this change are in the extension modules, but some core functions
4872 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4873 and many unicode/str methods.

4889 internal representation of a long.

4985 ``PyArg_ParseTupleAndKeywords()``, ``PyArg_VaParse()``,
4986 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept
4987 float arguments for integer format codes (other than 'L'): previously an
4988 attempt to pass a float resulted in a DeprecationWarning; now it gives a
4989 TypeError. For the 'L' format code (which previously had no warning) there is
4990 now a DeprecationWarning.

5038 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
5039 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00005040
Georg Brandlba83f822010-03-14 09:50:54 +00005041- Remove switch from "%f" formatting to "%g" formatting for floats larger than
5042 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00005043
Georg Brandlba83f822010-03-14 09:50:54 +00005044- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
5045 1e-100 used to raise OverflowError, but now gives the requested 120
5046 significant digits instead.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00005054
Georg Brandlba83f822010-03-14 09:50:54 +00005055- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
5056 decimal string that's guaranteed to round back to x under correct rounding
5057 (with round-half-to-even rounding mode). Previously it gave a string based on
5058 rounding x to 17 decimal digits. repr(x) for a complex number behaves
5059 similarly. On platforms where the correctly-rounded strtod and dtoa code is
5060 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005061
Georg Brandlba83f822010-03-14 09:50:54 +00005062- Issue #7117: On almost all platforms: float-to-string and string-to-float
5063 conversions within Python are now correctly rounded. Places these conversions
5064 occur include: str for floats and complex numbers; the float and complex
5065 constructors; old-style and new-style numeric formatting; serialization and
5066 deserialization of floats and complex numbers using marshal, pickle and json;
5067 parsing of float and imaginary literals in Python code; Decimal-to-float
5068 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005069
Georg Brandlba83f822010-03-14 09:50:54 +00005070 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
5071 providing correctly-rounded strtod and dtoa C functions. This code is
5072 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5073 the C compiler. There may be a small number of platforms on which correct
5074 operation of this code cannot be guaranteed, so the code is not used: notably,
5075 this applies to platforms where the C double format is not IEEE 754 binary64,
5076 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
5077 and Python's configure script is unable to determine how to change the FPU
5078 precision. On these platforms conversions use the platform strtod and dtoa,
5079 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005080
Georg Brandlba83f822010-03-14 09:50:54 +00005081- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5082 uses the correctly-rounded string <-> float conversions described above (when
5083 available), and so produces correctly rounded results that will display nicely
5084 under the float repr. There are two related small changes: (1) round now
5085 accepts any class with an ``__index__()`` method for its second argument (but
5086 no longer accepts floats for the second argument), and (2) an excessively
5087 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
5088 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00005218- Issue #5829: complex("1e500") no longer raises OverflowError. This makes it
5219 consistent with float("1e500") and interpretation of real and imaginary
5220 literals.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00005229- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
Mark Dickinsonb1d45852009-05-11 15:33:08 +00005230
Georg Brandlba83f822010-03-14 09:50:54 +00005231 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
5232 (2) parsing of strings representing infinities and nans was locale aware; and
5233 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').
Eric Smitha985a3a2009-05-05 18:26:08 +00005234
Georg Brandlba83f822010-03-14 09:50:54 +00005235- Issue #5920: For ``float.__format__()``, change the behavior with the empty
5236 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
5237 but with at least one decimal point and with a default precision
5238 of 12. Previously, the behavior the same but with a default precision of 6.
5239 This more closely matches ``str()``, and reduces surprises when adding
5240 alignment flags to the empty presentation type. This also affects the new
5241 complex.__format__ in the same way.
5242
5243- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
5244 classtype's, even if it was None. property now inserts the __doc__ into the
5245 subclass instance __dict__.

Antoine Pitrouf8387af2009-03-23 18:41:45 +00005305- Issue #4688: Add a heuristic so that tuples and dicts containing only
Georg Brandlba83f822010-03-14 09:50:54 +00005306 untrackable objects are not tracked by the garbage collector. This can reduce
5307 the size of collections and therefore the garbage collection overhead on

5315 internal representation of integers, for performance reasons. Base 2**30 is
5316 enabled by default on 64-bit machines. Add --enable-big-digits option to
5317 configure, which overrides the default. Add sys.long_info structseq to
5318 provide information about the internal format.

Georg Brandlba83f822010-03-14 09:50:54 +00005465- On windows, ``os.chdir()`` given unicode was not working if

5467 this code path is really executed because I cannot move to such directory on
5468 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00005470- Issue #4069: When ``set.remove(element)`` is used with a set element, the
5471 element is temporarily replaced with an equivalent frozenset. But the
5472 eventual KeyError would always report the empty ``frozenset()`` as the missing
5473 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00005493- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
5494 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
5495 step. This avoids problems with counting UTF-8 bytes that ignores the effect
5496 of using the replace error handler in PyUnicode_DecodeUTF8().
5497
Walter Dörwald726ba8e2009-05-06 14:32:35 +00005498- Issue #3739: The unicode-internal encoder now reports the number of characters

5500
Georg Brandlba83f822010-03-14 09:50:54 +00005501- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
5502 allocator will be automatically disabled when running under Valgrind. This
5503 gives improved memory leak detection when running under Valgrind, while taking
5504 advantage of pymalloc at other times.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00006872- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
6873
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006874- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6875 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6876 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6877 ``printf`` function, whereas PyString_FromFormat has an independent
6878 implementation and uses "%zd" on all platforms for size_t values.
6879 This makes a difference on win64, where ``printf`` needs "%Id" to display
6880 64bit values.
6881
Benjamin Peterson97179b02008-09-09 20:55:01 +00006882- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
6883 error.
6884
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00006885- Issue #3777: long() applied to a float object now always return a long
6886 object; previously an int would be returned for small values. the __long__
6887 method is allowed to return either an int or a long, but the behaviour of
6888 float objects should not change to respect backward compatibility.
6889
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00006890- Issue #3751: str.rpartition would perform a left-partition when called with
6891 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +00006896 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006897 was correctly parsed but parsing of subsequent arguments failed.
6898
Vinay Sajip35e3b032008-09-01 14:33:59 +00006899- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006900 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6901 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6902 when given a tuple of classes as second argument, were looking up
6903 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6904 type object.
6905
Neal Norwitz18aa3882008-08-24 05:04:52 +00006906- Fix crashes on memory allocation failure found with failmalloc.

Brett Cannon1eaf0742008-09-02 01:25:16 +00006975 warnings.catch_warnings() along with some API cleanup. Expanding the tests
6976 for catch_warnings() also led to an improvement in the raising of a

7049-----------------
7050
Guido van Rossumf8402962008-08-20 15:01:50 +00007051- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
7052 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
7053 extensions do not automatically benefit from the class attribute
7054 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
7055 to their tp_flags field if they care. This is a backwards
7056 compatibility feature; in 3.0, all types will use the cache by
7057 default.
7058
Benjamin Petersonf647dc12008-08-20 01:27:30 +00007059- Keyword arguments can now follow starred arguments. (``f(a, *args,
7060 keyword=23)`` is now valid syntax.)
7061
Thomas Heller0ad5ae02008-08-19 19:25:04 +00007062- ctypes function pointers that are COM methods have a boolean True
7063 value again.
7064
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00007065- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
7066 by denying s# to parse objects that have a releasebuffer procedure,
7067 and introducing s*.
7068
Georg Brandl1e13ea92008-08-11 09:07:59 +00007069- Issue #3537: Fix an assertion failure when an empty but presized dict
7070 object was stored in the freelist.
7071
Mark Dickinsonb6467572008-08-04 21:30:09 +00007072- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
7073 ValueError consistently across platforms.
7074
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00007075- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
7076 (64bit Unix, for example), unichr() would truncate its argument and return
7077 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
7078
Neal Norwitze7d8be82008-07-31 17:17:14 +00007079- Apply security patches from Apple.
7080
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00007081- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
7082 PyErr_ExceptionMatches returns 0 when an exception occurs there.
7083
Antoine Pitrou92f82162008-07-25 22:22:08 +00007084- Issue #1819: function calls with several named parameters are now on
7085 average 35% faster (as measured by pybench).
7086
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00007087- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
7088 the python debugger steps into a class statement: the free variables (local
7089 variables defined in an outer scope) would be deleted from the outer scope.
7090
Gregory P. Smith0470bab2008-07-22 04:46:32 +00007091- Issue #2620: Overflow checking when allocating or reallocating memory
7092 was not always being done properly in some python types and extension
7093 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
7094 all been updated to perform better checks and places in the code that
7095 would previously leak memory on the error path when such an allocation
7096 failed have been fixed.

Benjamin Petersone977ad42008-08-20 01:42:01 +00007103- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
7104 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
7105
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00007106- Issue #2234: distutils failed for some versions of the cygwin compiler. The
7107 version reported by these tools does not necessarily follow the python

7109
Nick Coghlanf70385a2008-08-18 12:42:46 +00007110- Issue #2235: Added Py3k warnings for types which will become unhashable
7111 under the stricter __hash__ inheritance rules in 3.0. Several types
7112 which did not meet the rules for hash invariants and were already
7113 unhashable in 3.0 have now been explicitly flagged as unhashable in
7114 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
7115 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
7116

7172 the reload() built-in has been removed.
7173
Brett Cannon7e30b672008-08-04 21:52:25 +00007174- Changed code in the following modules/packages to remove warnings raised

Antoine Pitroude781a42008-08-09 12:43:23 +00007186 asking for a specific length. This problem only affected files opened

7229 interaction with the tp_hash slot (added in 2.6b2) are now documented
7230
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00007231- Issue #643841: The language reference now provides more detailed
7232 coverage of the lookup process for special methods. The disclaimers
7233 regarding lack of coverage of new-style classes have also been
7234 removed, since the coverage is now fairly reasonable.

7238================================
7239
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007240*Release date: 17-Jul-2008*
7241
Raymond Hettingere3ae6552008-06-20 04:18:15 +00007242Core and Builtins
7243-----------------
7244
Georg Brandl3e483f62008-07-16 22:57:41 +00007245- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7246 its methods now allow for items objects that can be converted to
7247 an integer using operator.index().
7248
Mark Dickinson64b7e502008-07-16 09:40:03 +00007249- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7250 produced a ValueError instead of giving the correct float.
7251
Eric Smitha5fa5a22008-07-16 00:11:49 +00007252- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
7253 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
7254
Mark Dickinson7103aa42008-07-15 19:08:33 +00007255- Issue #3008: the float type has a new instance method 'float.hex'
7256 and a new class method 'float.fromhex' to convert floating-point
7257 numbers to and from hexadecimal strings, respectively.
7258
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007259- Issue #2235: __hash__ is once again inherited by default. To allow
7260 collections.Hashable to remain meaningful in the presence of the
7261 default hash implementation (object.__hash__), it is now possible
7262 to explicit block inheritance of hash by setting __hash__=None at
7263 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7264 level.
7265
Nick Coghlanb028f502008-07-13 14:52:36 +00007266- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7267 the parent module cannot be found while performing an absolute import.
7268 This means that an incorrectly defined __package__ attribute will
7269 now only prevent relative imports in that module rather than causing
7270 all imports from that module to fail.
7271
Nick Coghlan14ff9942008-07-08 14:21:42 +00007272- Issue #2517: Allow unicode messages in Exceptions again by correctly
7273 bypassing the instance dictionary when looking up __unicode__ on
7274 new-style classes.
7275
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00007276- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
7277 set to a custom object whose write() method happens to install
7278 another file in sys.stdout.
7279
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00007280- Issue #3088: Corrected a race condition in classes derived from
7281 threading.local: the first member set by a thread could be saved in
7282 another thread's dictionary.
7283
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007284- Issue #3004: Minor change to slice.indices(): the start and stop
7285 arguments are now treated identically, making the behaviour easier
7286 to describe and understand. For example, slice(None, -10,
7287 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7288 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7289 10, -1).
7290
Georg Brandl278fc502008-07-19 12:46:12 +00007291- Issue #3219: Calling a function with repeated keyword arguments,
7292 f(a=2, a=23), would not cause a syntax error. This was a regression
7293 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00007294
Georg Brandl278fc502008-07-19 12:46:12 +00007295- Issue #2862: Make int and float freelist management consistent with
7296 other freelists. Changes their CompactFreeList apis into
7297 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00007302- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
7303 api functions without holding the GIL, which could lead to a fatal
7304 error when they failed.
7305
Martin v. Löwisaabf4042008-08-02 07:20:25 +00007306- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Vinay Sajip51e65192008-07-18 09:01:10 +00007317- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007331- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
7332 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007333 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007334 content-length. The problem had been corrected in the 2.4 branch, but never
7335 merged into trunk.
7336

Nick Coghlanc060b0e2008-07-02 13:09:19 +00007350- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
7351 handling is now the same as that of other special attributes like __name__).
7352
Brett Cannon8bb8fa52008-07-02 01:57:08 +00007353- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
7354 removal in Python 3.0 in favor of urllib2.urlopen().

Ronald Oussoren5640ce22008-06-05 12:58:24 +00007739- On MacOS X it is now possible to install the framework in 64-bit
7740 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00007741 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007742
7743 This is controlled by the configure argument ``--with-universal-archs``:
7744
7745 - ``--with-universal-archs=all``: install 4-way universal
7746
7747 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7748
7749 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7750
7751 This option should be used in combination with ``--enable-universalsdk=``.
7752
7753 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 +00007802- Issue #1631171: Re-implement the 'warnings' module in C (the
7803 original Python code has been kept as backup). This will allow for
7804 using the 'warning's machinery in such places as the parser where
7805 use of pure Python code is not possible. Both the ``showarning()``
7806 and ``formatwarning()`` gain an optional 'line' argument which is
7807 not called by default for backwards-compatibility reasons. Setting
7808 ``warnings.showwarning()`` to an implementation that lacks support
7809 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007872- Issue #2550: The approach used by client/server code for obtaining
7873 ports to listen on in network-oriented tests has been refined in an
7874 effort to facilitate running multiple instances of the entire
7875 regression test suite in parallel without issue.
7876 test_support.bind_port() has been fixed such that it will always
7877 return a unique port -- which wasn't always the case with the
7878 previous implementation, especially if socket options had been set
7879 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7880 new implementation of bind_port() will actually raise an exception
7881 if it is passed an AF_INET/SOCK_STREAM socket with either the
7882 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7883 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7884 the socket it's been passed. This currently only applies to
7885 Windows. This option prevents any other sockets from binding to the
7886 host/port we've bound to, thus removing the possibility of the
7887 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7888 when a second SOCK_STREAM socket binds and accepts to a host/port
7889 that's already been bound by another socket. The optional preferred
7890 port parameter to bind_port() has been removed. Under no
7891 circumstances should tests be hard coding ports!
7892
7893 test_support.find_unused_port() has also been introduced, which will
7894 pass a temporary socket object to bind_port() in order to obtain an
7895 unused port. The temporary socket object is then closed and
7896 deleted, and the port is returned. This method should only be used
7897 for obtaining an unused port in order to pass to an external program
7898 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7899 a parameter to a server-oriented class that doesn't give you direct
7900 access to the underlying socket used.
7901
7902 Finally, test_support.HOST has been introduced, which should be used
7903 for the host argument of any relevant socket calls (i.e. bind and
7904 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007905
7906 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007907 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007908 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7909 test_asynchat and test_socket_ssl.
7910
Georg Brandl3ee81df2008-05-17 18:14:43 +00007911 It is now possible for multiple instances of the regression test
7912 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00007966- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00007967 \Uxxxxxxxx did not accept values outside the Basic Multilingual
7968 Plane. This affected raw unicode literals and the
7969 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
7970 this case, like normal unicode literals and the 'unicode-escape'
7971 codec.

8194 differ slightly in their output formats from the existing, unchanged
8195 Python 2.6 builtins. The expected usage of the future_builtins
8196 module is:
8197 from future_builtins import hex, oct
8198
Eric Smith7ef40bf2008-02-20 23:34:22 +00008199- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8200 exponents for exponents with absolute value < 100. Follows C99
8201 standard. This is a change on Windows, which would use 3 digits.
8202 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8203 so that any alterations it does to the resulting string will be
8204 available in stringlib/formatter.h (for float.__format__).
8205
Eric Smith5a3c1352008-02-19 13:21:56 +00008206- Implemented PEP 3101, Advanced String Formatting. This adds a new
8207 builtin format(); a format() method for str and unicode; a
8208 __format__() method to object, str, unicode, int, long, float, and
8209 datetime; the class string.Formatter; and the C API
8210 PyObject_Format().
8211
Georg Brandl3ee81df2008-05-17 18:14:43 +00008212- Fixed several potential crashes, all caused by specially crafted
8213 __del__ methods exploiting objects in temporarily inconsistent
8214 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00008215
Vinay Sajipb7edfc42008-04-02 21:10:23 +00008216- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00008217 prevent a possible crash: an Abstract Base Class would try to access
8218 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00008219

Georg Brandl3ee81df2008-05-17 18:14:43 +00008223- Clear all free lists during a gc.collect() of the highest generation
8224 in order to allow pymalloc to free more arenas. Python may give back
8225 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008226
Georg Brandl3ee81df2008-05-17 18:14:43 +00008227- Issue #2045: Fix an infinite recursion triggered when printing a
8228 subclass of collections.defaultdict, if its default_factory is set
8229 to a bound method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008257- Patch #1473257: generator objects gain a gi_code attribute. This is
8258 the same object as the func_code attribute of the function that
8259 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008260
Georg Brandl3ee81df2008-05-17 18:14:43 +00008261- Issue #1920: "while 0" statements were completely removed by the
8262 compiler, even in the presence of an "else" clause, which is
8263 supposed to be run when the condition is false. Now the compiler
8264 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008265
Guido van Rossumeead05f2008-01-24 18:21:02 +00008266- A few crashers fixed: weakref_in_del.py (issue #1377858);

8273
Georg Brandl3ee81df2008-05-17 18:14:43 +00008274- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00008275 several extension methods and modules do not work without unicode
8276 support.
8277
Georg Brandl26543b12008-01-21 18:36:51 +00008278- Issue #1882: when compiling code from a string, encoding cookies in the

8282
Georg Brandl6caad7d2008-01-26 14:19:22 +00008283- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008284 added.
8285
Christian Heimesc94e2b52008-01-14 04:13:37 +00008286- sys.float_info / PyFloat_GetInfo: The floating point information
8287 object was converted from a dict to a specialized structseq object.
8288
Georg Brandl3ee81df2008-05-17 18:14:43 +00008289- Patch #1816: Added sys.flags structseq. It exposes the status of
8290 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008291
Georg Brandl3ee81df2008-05-17 18:14:43 +00008292- Objects/structseq.c: Implemented new structseq representation. The
8293 patch makes structseqs (e.g. the return value of os.stat) more
8294 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00008295
Georg Brandl3ee81df2008-05-17 18:14:43 +00008296- Patch #1700288: added a type attribute cache that caches method
8297 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00008298
Neal Norwitz3fc15b82008-01-10 05:42:58 +00008299- Bug #1776: __import__() no longer accepts filenames on any platform.

8305 envvar and sys.dont_write_bytecode attribute. All these can be set
8306 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00008307
Georg Brandl3ee81df2008-05-17 18:14:43 +00008308- Improve some exception messages when Windows fails to load an
8309 extension module. Now we get for example '%1 is not a valid Win32
8310 application' instead of 'error code 193'.

8367
Georg Brandl21e99f42010-03-07 15:23:59 +00008368- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008369 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8370 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008371
Georg Brandl3ee81df2008-05-17 18:14:43 +00008372- Issue #1686386: Tuple's tp_repr did not take into account the
8373 possibility of having a self-referential tuple, which is possible
8374 from C code. Nor did object's tp_str consider that a type's tp_str
8375 could do something that could lead to an inifinite recursion.
8376 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8377 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008378
Georg Brandl3ee81df2008-05-17 18:14:43 +00008379- Issue #1164: It was possible to trigger deadlock when using the
8380 'print' statement to write to a file since the GIL was not released
8381 as needed. Now PyObject_Print() does the right thing along with
8382 various tp_print implementations of the built-in types and those in
8383 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00008384
Georg Brandl3ee81df2008-05-17 18:14:43 +00008385- Issue #1147: Exceptions were directly allowing string exceptions in

Georg Brandl3ee81df2008-05-17 18:14:43 +00008393 PyObject_Call() never calling back out to Python code to trigger
8394 recursion depth updates/checks. Required the creation of a static
8395 RuntimeError instance in case normalizing an exception put the
8396 recursion check value past its limit. Fixes crashers

Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008436- Request #1193128: str.translate() now allows a None argument for
8437 translations that only remove characters without re-mapping the
8438 remaining characters.
8439
Georg Brandl5cb76c12007-03-21 09:00:39 +00008440- Patch #1682205: a TypeError while unpacking an iterable is no longer
8441 masked by a generic one with the message "unpack non-sequence".

8444
Guido van Rossum143b5642007-03-23 04:58:42 +00008445- Bug #1683368: The object.__init__() and object.__new__() methods are
8446 now stricter in rejecting excess arguments. The only time when
8447 either allows excess arguments is when it is not overridden and the
8448 other one is. For backwards compatibility, when both are
8449 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008450 warning later). Also, type.__init__() insists on the same signature
8451 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00008453- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8454 object to complex using its __complex__() method before falling back
8455 to the __float__() method. Therefore, the functions in the cmath
8456 module now can operate on objects that define a __complex__()
8457 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00008475- Bug #1678647: write a newline after printing an exception in any
8476 case, even when converting the value to a string failed.
8477
Georg Brandl871f1bc2007-03-12 13:17:36 +00008478- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008479 its argument, if it exists. If not, it will work like before. This
8480 allows customizing the output of dir() in the presence of a
8481 __getattr__().

8491 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008492
Georg Brandlaa2321b2007-03-07 00:40:28 +00008493- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008494 makes the filenames the warning module prints much more sensible
8495 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00008496

8509 sq_ass_slice instead of the sq_slice slot.
8510
Georg Brandl3ee81df2008-05-17 18:14:43 +00008511- When printing an unraisable error, don't print exceptions. before

Neal Norwitzcbeb6872006-10-14 21:33:38 +00008562
Georg Brandl2c1375c2006-10-12 11:27:59 +00008563- Bug #1545497: when given an explicit base, int() did ignore NULs
8564 embedded in the string to convert.
8565
Georg Brandl846f73a2006-10-08 07:11:54 +00008566- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl4e933132006-09-06 20:05:58 +00008596- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008614 generator expressions (x for x, in ... ) works again. Fixing this
8615 problem required changing the .pyc magic number. This means that

Guido van Rossum8bc09652008-02-21 18:18:37 +00008654- Removed uses of dict.has_key() from distutils, and uses of
8655 callable() from copy_reg.py, so the interpreter now starts up

9410 longer than 3 bytes.
Georg Brandl27562782006-10-27 20:39:43 +00009411
Georg Brandl3ee81df2008-05-17 18:14:43 +00009412- The implementation of UnicodeError objects has been simplified
9413 (start and end attributes are now stored directly as Py_ssize_t
9414 members).

Georg Brandl3ee81df2008-05-17 18:14:43 +00009416- Issue #829951: In the smtplib module, SMTP.starttls() now complies
9417 with RFC 3207 and forgets any knowledge obtained from the server not
9418 obtained from the TLS negotiation itself. Patch contributed by Bill
9419 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00009420
Georg Brandl3ee81df2008-05-17 18:14:43 +00009421- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00009422 that the SMTP.starttls() caller no longer needs to call ehlo()
9423 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00009424 does not claim to support starttls. Adds the
9425 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
9426 Fenner.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009468- Patch #976880: ``mmap`` objects now have an ``rfind`` method that
Andrew M. Kuchling5c60bfc2008-01-19 18:18:41 +00009469 works as expected. ``mmap.find`` also takes an optional ``end``
9470 parameter.

9495 contents before adding elements from the iterable. This fix brings
9496 the behavior into line with that for list.__init__().
Raymond Hettingeradf9ffd2007-12-13 00:08:37 +00009497
Georg Brandl3ee81df2008-05-17 18:14:43 +00009498- Added wide char functions to msvcrt module: getwch, getwche, putwch

9504
Georg Brandl3ee81df2008-05-17 18:14:43 +00009505- Marshal.dumps() now expects exact type matches for int, long, float,
9506 complex, tuple, list, dict, set, and frozenset. Formerly, it would
9507 silently miscode subclasses of those types. Now, it raises a
9508 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00009509

Georg Brandl3ee81df2008-05-17 18:14:43 +00009524 time so that opening a database previously created with the DB_DUP
9525 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9526 opens. Specifically: dictionary assignment to a DB object will
9527 replace all values for a given key when the database allows
9528 duplicate values. DB users should use DB.put(k, v) when they want
9529 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009530

9536 characters with ASCII value less than 32. Also, it correctly quotes
9537 dots only if they occur on a single line, as opposed to the previous
9538 behavior of quoting dots if they are the second character of any
9539 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00009540

9569 negative numbers, per the underlying C implementation.
Guido van Rossumbb2cc692007-01-14 17:03:32 +00009570

Georg Brandl3ee81df2008-05-17 18:14:43 +00009948- Removed the macfs module. It had been deprecated since Python 2.5.
9949 This lead to the deprecation of macostools.touched() as it relied
