1122 In particular, fix extension module build failures when trying to use
1123 32-bit-only installer Pythons on systems with Xcode 4 (currently
1124 OS X 10.8, 10.7, and optionally 10.6).
1125 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1126 * Since Xcode 4 removes ppc support, extension module builds now
1127 check for ppc compiler support and by default remove ppc and
1128 ppc64 archs when they are not available.
1129 * Extension module builds now revert to using system installed
1130 headers and libs (/usr and /System/Library) if the SDK used
1131 to build the interpreter is not installed or has moved.
1132 * Try to avoid building extension modules with deprecated
1133 and problematic Apple llvm-gcc compiler. If original compiler
1134 is not available, use clang instead by default.

Mark Dickinsondbbed042011-09-19 16:38:08 +01001485- Issue #12973: Fix overflow checks that invoked undefined behaviour in
1486 int.__pow__. These overflow checks were causing int.__pow__ to produce
1487 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +01001488 compiler optimizing the check away. Also fix similar overflow checks
1489 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
1490 bugs caused test failures with recent versions of Clang.

Florent Xiclunac2279652012-02-12 14:49:03 +01001558- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01001559 has left two versions of customize_compiler, the original in
1560 distutils.sysconfig and another copy in distutils.ccompiler, with some

1563 is the case in 3.x.

Ned Deily0d0ea482012-02-10 12:59:06 +01001565- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1566 Distutils-based packages with C extension modules may fail because
1567 Apple has removed gcc-4.2, the version used to build python.org
1568 64-bit/32-bit Pythons. If the user does not explicitly override
1569 the default C compiler by setting the CC environment variable,
1570 Distutils will now attempt to compile extension modules with clang
1571 if gcc-4.2 is required but not found. Also as a convenience, if
1572 the user does explicitly set CC, substitute its value as the default
1573 compiler in the Distutils LDSHARED configuration variable for OS X.
1574 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1575 SDK, neither of which are available in Xcode 4. This change does not
1576 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001826- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1827 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1828 interpreter process. This could cause failures in non-Distutils subprocesses
1829 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02001830 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07001831 deployment target only in the environment of each build subprocess. It is
1832 still possible to globally override the default by setting
1833 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1834 greater or equal to the default value, the value with which the interpreter
1835 was built.

1864 updating the check interval, so if the user decreases the check interval,
1865 the ticker doesn't have to wind down to zero from the old starting point
1866 before the new interval takes effect. And if the user increases the
1867 interval, it makes sure the new limit takes effect right away rather have an
1868 early task switch before recognizing the new interval.

Raymond Hettinger20397532010-09-12 02:11:45 +00002848- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
2849 This prevents user-created self-referencing ordered dictionaries from
2850 becoming permanently uncollectable GC garbage. The downside is that
2851 removing __del__ means that the internal doubly-linked list has to wait for
2852 GC collection rather than freeing memory immediately when the refcnt drops
2853 to zero.

2861 to fetch the original errno, or to filter timeout errors. Now the
2862 original error is re-raised.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003312- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3313 start byte and the continuation byte(s) are now considered invalid, instead
3314 of the number of bytes specified by the start byte.
3315 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3316 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3317 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00003326- Issue #8748: Fix two issues with comparisons between complex and integer
3327 objects. (1) The comparison could incorrectly return True in some cases
3328 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
3329 (2) The comparison raised an OverflowError for large integers, leading
3330 to unpredictable exceptions when combining integers and complex objects
3331 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +00003333- Issue #5211: Implicit coercion for the complex type is now completely

Georg Brandlba83f822010-03-14 09:50:54 +00004211 file position when calling `truncate()`. It would previously change the file
4212 position to the given argument, which goes against the tradition of

4216 class used to represent files stored inside an archive. The new
4217 implementation is significantly faster and can be wrapped in a
4218 ``io.BufferedReader`` object for more speedups. It also solves an issue
4219 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

4308-----------------
4309
Georg Brandlba83f822010-03-14 09:50:54 +00004310- The ``__complex__()`` method is now looked up on the class of instances to
4311 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00004313- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
4314 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
4315
Mark Dickinson1b34d252010-01-01 17:27:30 +00004316- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004317 DeprecationWarning when passed a float argument where an integer was expected.
4318 These functions and methods now raise TypeError instead. The majority of the
4319 effects of this change are in the extension modules, but some core functions
4320 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4321 and many unicode/str methods.

4335 of integers: the result of a/b is now correctly rounded for ints a and b (at
4336 least on IEEE 754 platforms), and in particular does not depend on the
4337 internal representation of a long.

4345
Georg Brandlba83f822010-03-14 09:50:54 +00004346 These executables now work properly with the arch(1) command: ``arch -ppc
4347 python`` will start a universal binary version of python in PPC mode (unlike

4434 ``PyArg_ParseTupleAndKeywords()``, ``PyArg_VaParse()``,
4435 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept
4436 float arguments for integer format codes (other than 'L'): previously an
4437 attempt to pass a float resulted in a DeprecationWarning; now it gives a
4438 TypeError. For the 'L' format code (which previously had no warning) there is
4439 now a DeprecationWarning.

4488 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00004489

4491 1e50 in absolute value.

Georg Brandlba83f822010-03-14 09:50:54 +00004493- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
4494 1e-100 used to raise OverflowError, but now gives the requested 120
4495 significant digits instead.

Georg Brandlba83f822010-03-14 09:50:54 +00004504- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4505 decimal string that's guaranteed to round back to x under correct rounding
4506 (with round-half-to-even rounding mode). Previously it gave a string based on
4507 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4508 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4509 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004510
Georg Brandlba83f822010-03-14 09:50:54 +00004511- Issue #7117: On almost all platforms: float-to-string and string-to-float
4512 conversions within Python are now correctly rounded. Places these conversions
4513 occur include: str for floats and complex numbers; the float and complex
4514 constructors; old-style and new-style numeric formatting; serialization and
4515 deserialization of floats and complex numbers using marshal, pickle and json;
4516 parsing of float and imaginary literals in Python code; Decimal-to-float
4517 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004518
Georg Brandlba83f822010-03-14 09:50:54 +00004519 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4520 providing correctly-rounded strtod and dtoa C functions. This code is
4521 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4522 the C compiler. There may be a small number of platforms on which correct
4523 operation of this code cannot be guaranteed, so the code is not used: notably,
4524 this applies to platforms where the C double format is not IEEE 754 binary64,
4525 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4526 and Python's configure script is unable to determine how to change the FPU
4527 precision. On these platforms conversions use the platform strtod and dtoa,
4528 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004529
Georg Brandlba83f822010-03-14 09:50:54 +00004530- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4531 uses the correctly-rounded string <-> float conversions described above (when
4532 available), and so produces correctly rounded results that will display nicely
4533 under the float repr. There are two related small changes: (1) round now
4534 accepts any class with an ``__index__()`` method for its second argument (but
4535 no longer accepts floats for the second argument), and (2) an excessively
4536 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4537 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00004679
Georg Brandlba83f822010-03-14 09:50:54 +00004680 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
4681 (2) parsing of strings representing infinities and nans was locale aware; and
4682 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00004684- Issue #5920: For ``float.__format__()``, change the behavior with the empty
4685 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
4686 but with at least one decimal point and with a default precision
4687 of 12. Previously, the behavior the same but with a default precision of 6.
4688 This more closely matches ``str()``, and reduces surprises when adding
4689 alignment flags to the empty presentation type. This also affects the new
4690 complex.__format__ in the same way.
4691
4692- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

6123 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
6124 neither __int__ nor __long__, TypeError used to be raised (with a

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00006321- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
6322
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006323- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6324 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6325 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6326 ``printf`` function, whereas PyString_FromFormat has an independent
6327 implementation and uses "%zd" on all platforms for size_t values.
6328 This makes a difference on win64, where ``printf`` needs "%Id" to display
6329 64bit values.
6330
Benjamin Peterson97179b02008-09-09 20:55:01 +00006331- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

6333
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00006334- Issue #3777: long() applied to a float object now always return a long
6335 object; previously an int would be returned for small values. the __long__
6336 method is allowed to return either an int or a long, but the behaviour of
6337 float objects should not change to respect backward compatibility.
6338
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00006339- Issue #3751: str.rpartition would perform a left-partition when called with
6340 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +00006345 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006346 was correctly parsed but parsing of subsequent arguments failed.
6347
Vinay Sajip35e3b032008-09-01 14:33:59 +00006348- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006349 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6350 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6351 when given a tuple of classes as second argument, were looking up
6352 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6353 type object.
6354
Neal Norwitz18aa3882008-08-24 05:04:52 +00006355- Fix crashes on memory allocation failure found with failmalloc.

Brett Cannon1eaf0742008-09-02 01:25:16 +00006424 warnings.catch_warnings() along with some API cleanup. Expanding the tests
6425 for catch_warnings() also led to an improvement in the raising of a

6498-----------------
6499
Guido van Rossumf8402962008-08-20 15:01:50 +00006500- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6501 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6502 extensions do not automatically benefit from the class attribute
6503 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6504 to their tp_flags field if they care. This is a backwards
6505 compatibility feature; in 3.0, all types will use the cache by
6506 default.
6507
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006508- Keyword arguments can now follow starred arguments. (``f(a, *args,
6509 keyword=23)`` is now valid syntax.)
6510
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006511- ctypes function pointers that are COM methods have a boolean True
6512 value again.
6513
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006514- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6515 by denying s# to parse objects that have a releasebuffer procedure,
6516 and introducing s*.
6517
Georg Brandl1e13ea92008-08-11 09:07:59 +00006518- Issue #3537: Fix an assertion failure when an empty but presized dict
6519 object was stored in the freelist.
6520
Mark Dickinsonb6467572008-08-04 21:30:09 +00006521- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6522 ValueError consistently across platforms.
6523
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006524- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6525 (64bit Unix, for example), unichr() would truncate its argument and return
6526 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6527
Neal Norwitze7d8be82008-07-31 17:17:14 +00006528- Apply security patches from Apple.
6529
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006530- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6531 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6532
Antoine Pitrou92f82162008-07-25 22:22:08 +00006533- Issue #1819: function calls with several named parameters are now on
6534 average 35% faster (as measured by pybench).
6535
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006536- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6537 the python debugger steps into a class statement: the free variables (local
6538 variables defined in an outer scope) would be deleted from the outer scope.
6539
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006540- Issue #2620: Overflow checking when allocating or reallocating memory
6541 was not always being done properly in some python types and extension
6542 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6543 all been updated to perform better checks and places in the code that
6544 would previously leak memory on the error path when such an allocation
6545 failed have been fixed.

6551
Benjamin Petersone977ad42008-08-20 01:42:01 +00006552- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of

6554
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006555- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6556 version reported by these tools does not necessarily follow the python
6557 version numbering scheme, so the module is less strict when parsing it.
6558
Nick Coghlanf70385a2008-08-18 12:42:46 +00006559- Issue #2235: Added Py3k warnings for types which will become unhashable
6560 under the stricter __hash__ inheritance rules in 3.0. Several types
6561 which did not meet the rules for hash invariants and were already
6562 unhashable in 3.0 have now been explicitly flagged as unhashable in
6563 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6564 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6565

6621 the reload() built-in has been removed.
6622
Brett Cannon7e30b672008-08-04 21:52:25 +00006623- Changed code in the following modules/packages to remove warnings raised

Antoine Pitroude781a42008-08-09 12:43:23 +00006635 asking for a specific length. This problem only affected files opened
6636 using the new "io" module, not the built-in open() function.

6678 interaction with the tp_hash slot (added in 2.6b2) are now documented
6679
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00006680- Issue #643841: The language reference now provides more detailed
6681 coverage of the lookup process for special methods. The disclaimers
6682 regarding lack of coverage of new-style classes have also been
6683 removed, since the coverage is now fairly reasonable.

6687================================
6688
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006689*Release date: 17-Jul-2008*
6690
Raymond Hettingere3ae6552008-06-20 04:18:15 +00006691Core and Builtins
6692-----------------
6693
Georg Brandl3e483f62008-07-16 22:57:41 +00006694- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6695 its methods now allow for items objects that can be converted to
6696 an integer using operator.index().
6697
Mark Dickinson64b7e502008-07-16 09:40:03 +00006698- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6699 produced a ValueError instead of giving the correct float.
6700
Eric Smitha5fa5a22008-07-16 00:11:49 +00006701- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6702 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6703
Mark Dickinson7103aa42008-07-15 19:08:33 +00006704- Issue #3008: the float type has a new instance method 'float.hex'
6705 and a new class method 'float.fromhex' to convert floating-point
6706 numbers to and from hexadecimal strings, respectively.
6707
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006708- Issue #2235: __hash__ is once again inherited by default. To allow
6709 collections.Hashable to remain meaningful in the presence of the
6710 default hash implementation (object.__hash__), it is now possible
6711 to explicit block inheritance of hash by setting __hash__=None at
6712 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6713 level.
6714
Nick Coghlanb028f502008-07-13 14:52:36 +00006715- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6716 the parent module cannot be found while performing an absolute import.
6717 This means that an incorrectly defined __package__ attribute will
6718 now only prevent relative imports in that module rather than causing
6719 all imports from that module to fail.
6720
Nick Coghlan14ff9942008-07-08 14:21:42 +00006721- Issue #2517: Allow unicode messages in Exceptions again by correctly
6722 bypassing the instance dictionary when looking up __unicode__ on
6723 new-style classes.
6724
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00006725- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
6726 set to a custom object whose write() method happens to install
6727 another file in sys.stdout.
6728
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00006729- Issue #3088: Corrected a race condition in classes derived from
6730 threading.local: the first member set by a thread could be saved in
6731 another thread's dictionary.
6732
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006733- Issue #3004: Minor change to slice.indices(): the start and stop
6734 arguments are now treated identically, making the behaviour easier
6735 to describe and understand. For example, slice(None, -10,
6736 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6737 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6738 10, -1).
6739
Georg Brandl278fc502008-07-19 12:46:12 +00006740- Issue #3219: Calling a function with repeated keyword arguments,
6741 f(a=2, a=23), would not cause a syntax error. This was a regression
6742 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00006743
Georg Brandl278fc502008-07-19 12:46:12 +00006744- Issue #2862: Make int and float freelist management consistent with
6745 other freelists. Changes their CompactFreeList apis into
6746 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00006747

Thomas Heller57adf222008-08-14 19:10:48 +00006751- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
6752 api functions without holding the GIL, which could lead to a fatal
6753 error when they failed.
6754
Martin v. Löwisaabf4042008-08-02 07:20:25 +00006755- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

6764 ForkingPickler.register() to resolve conflict with ctypes.
6765
Vinay Sajip51e65192008-07-18 09:01:10 +00006766- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

6769 a valid dlerror() message.
6770
Thomas Heller2bad6572008-07-15 17:19:50 +00006771- Issue #3258: Fixed a crash when a ctypes POINTER type to an

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006778- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00006779
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006780- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
6781 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006782 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006783 content-length. The problem had been corrected in the 2.4 branch, but never
6784 merged into trunk.
6785

Nick Coghlanc060b0e2008-07-02 13:09:19 +00006799- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
6800 handling is now the same as that of other special attributes like __name__).
6801
Brett Cannon8bb8fa52008-07-02 01:57:08 +00006802- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
6803 removal in Python 3.0 in favor of urllib2.urlopen().

Ronald Oussoren5640ce22008-06-05 12:58:24 +00007190- On MacOS X it is now possible to install the framework in 64-bit
7191 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00007192 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007193
7194 This is controlled by the configure argument ``--with-universal-archs``:
7195
7196 - ``--with-universal-archs=all``: install 4-way universal
7197
7198 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7199
7200 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7201
7202 This option should be used in combination with ``--enable-universalsdk=``.
7203
7204 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 +00007254- Issue #1631171: Re-implement the 'warnings' module in C (the
7255 original Python code has been kept as backup). This will allow for
7256 using the 'warning's machinery in such places as the parser where
7257 use of pure Python code is not possible. Both the ``showarning()``
7258 and ``formatwarning()`` gain an optional 'line' argument which is
7259 not called by default for backwards-compatibility reasons. Setting
7260 ``warnings.showwarning()`` to an implementation that lacks support
7261 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007303- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00007304 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00007324- Issue #2550: The approach used by client/server code for obtaining
7325 ports to listen on in network-oriented tests has been refined in an
7326 effort to facilitate running multiple instances of the entire
7327 regression test suite in parallel without issue.
7328 test_support.bind_port() has been fixed such that it will always
7329 return a unique port -- which wasn't always the case with the
7330 previous implementation, especially if socket options had been set
7331 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7332 new implementation of bind_port() will actually raise an exception
7333 if it is passed an AF_INET/SOCK_STREAM socket with either the
7334 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7335 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7336 the socket it's been passed. This currently only applies to
7337 Windows. This option prevents any other sockets from binding to the
7338 host/port we've bound to, thus removing the possibility of the
7339 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7340 when a second SOCK_STREAM socket binds and accepts to a host/port
7341 that's already been bound by another socket. The optional preferred
7342 port parameter to bind_port() has been removed. Under no
7343 circumstances should tests be hard coding ports!
7344
7345 test_support.find_unused_port() has also been introduced, which will
7346 pass a temporary socket object to bind_port() in order to obtain an
7347 unused port. The temporary socket object is then closed and
7348 deleted, and the port is returned. This method should only be used
7349 for obtaining an unused port in order to pass to an external program
7350 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7351 a parameter to a server-oriented class that doesn't give you direct
7352 access to the underlying socket used.
7353
7354 Finally, test_support.HOST has been introduced, which should be used
7355 for the host argument of any relevant socket calls (i.e. bind and
7356 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007357
7358 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007359 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007360 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7361 test_asynchat and test_socket_ssl.
7362
Georg Brandl3ee81df2008-05-17 18:14:43 +00007363 It is now possible for multiple instances of the regression test
7364 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00007418- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00007419 \Uxxxxxxxx did not accept values outside the Basic Multilingual
7420 Plane. This affected raw unicode literals and the
7421 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
7422 this case, like normal unicode literals and the 'unicode-escape'
7423 codec.

7647 Python 2.6 builtins. The expected usage of the future_builtins
7648 module is:
7649 from future_builtins import hex, oct
7650
Eric Smith7ef40bf2008-02-20 23:34:22 +00007651- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7652 exponents for exponents with absolute value < 100. Follows C99
7653 standard. This is a change on Windows, which would use 3 digits.
7654 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7655 so that any alterations it does to the resulting string will be
7656 available in stringlib/formatter.h (for float.__format__).
7657
Eric Smith5a3c1352008-02-19 13:21:56 +00007658- Implemented PEP 3101, Advanced String Formatting. This adds a new
7659 builtin format(); a format() method for str and unicode; a
7660 __format__() method to object, str, unicode, int, long, float, and
7661 datetime; the class string.Formatter; and the C API
7662 PyObject_Format().
7663
Georg Brandl3ee81df2008-05-17 18:14:43 +00007664- Fixed several potential crashes, all caused by specially crafted
7665 __del__ methods exploiting objects in temporarily inconsistent
7666 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00007667
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007668- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00007669 prevent a possible crash: an Abstract Base Class would try to access
7670 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00007671

Georg Brandl3ee81df2008-05-17 18:14:43 +00007675- Clear all free lists during a gc.collect() of the highest generation
7676 in order to allow pymalloc to free more arenas. Python may give back
7677 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007678
Georg Brandl3ee81df2008-05-17 18:14:43 +00007679- Issue #2045: Fix an infinite recursion triggered when printing a
7680 subclass of collections.defaultdict, if its default_factory is set
7681 to a bound method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007709- Patch #1473257: generator objects gain a gi_code attribute. This is
7710 the same object as the func_code attribute of the function that
7711 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007712
Georg Brandl3ee81df2008-05-17 18:14:43 +00007713- Issue #1920: "while 0" statements were completely removed by the
7714 compiler, even in the presence of an "else" clause, which is
7715 supposed to be run when the condition is false. Now the compiler
7716 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007717
Guido van Rossumeead05f2008-01-24 18:21:02 +00007718- A few crashers fixed: weakref_in_del.py (issue #1377858);

7725
Georg Brandl3ee81df2008-05-17 18:14:43 +00007726- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007727 several extension methods and modules do not work without unicode
7728 support.
7729
Georg Brandl26543b12008-01-21 18:36:51 +00007730- Issue #1882: when compiling code from a string, encoding cookies in the

7734
Georg Brandl6caad7d2008-01-26 14:19:22 +00007735- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007736 added.
7737
Christian Heimesc94e2b52008-01-14 04:13:37 +00007738- sys.float_info / PyFloat_GetInfo: The floating point information
7739 object was converted from a dict to a specialized structseq object.
7740
Georg Brandl3ee81df2008-05-17 18:14:43 +00007741- Patch #1816: Added sys.flags structseq. It exposes the status of
7742 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007743
Georg Brandl3ee81df2008-05-17 18:14:43 +00007744- Objects/structseq.c: Implemented new structseq representation. The
7745 patch makes structseqs (e.g. the return value of os.stat) more
7746 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007747
Georg Brandl3ee81df2008-05-17 18:14:43 +00007748- Patch #1700288: added a type attribute cache that caches method
7749 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00007750
Neal Norwitz3fc15b82008-01-10 05:42:58 +00007751- Bug #1776: __import__() no longer accepts filenames on any platform.

7757 envvar and sys.dont_write_bytecode attribute. All these can be set
7758 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007759
Georg Brandl3ee81df2008-05-17 18:14:43 +00007760- Improve some exception messages when Windows fails to load an
7761 extension module. Now we get for example '%1 is not a valid Win32
7762 application' instead of 'error code 193'.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007821 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7822 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007823
Georg Brandl3ee81df2008-05-17 18:14:43 +00007824- Issue #1686386: Tuple's tp_repr did not take into account the
7825 possibility of having a self-referential tuple, which is possible
7826 from C code. Nor did object's tp_str consider that a type's tp_str
7827 could do something that could lead to an inifinite recursion.
7828 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7829 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007830
Georg Brandl3ee81df2008-05-17 18:14:43 +00007831- Issue #1164: It was possible to trigger deadlock when using the
7832 'print' statement to write to a file since the GIL was not released
7833 as needed. Now PyObject_Print() does the right thing along with
7834 various tp_print implementations of the built-in types and those in
7835 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007845 PyObject_Call() never calling back out to Python code to trigger
7846 recursion depth updates/checks. Required the creation of a static

Raymond Hettinger4db5fe92007-04-12 04:10:00 +00007888- Request #1193128: str.translate() now allows a None argument for
7889 translations that only remove characters without re-mapping the
7890 remaining characters.
7891
Georg Brandl5cb76c12007-03-21 09:00:39 +00007892- Patch #1682205: a TypeError while unpacking an iterable is no longer
7893 masked by a generic one with the message "unpack non-sequence".

7896
Guido van Rossum143b5642007-03-23 04:58:42 +00007897- Bug #1683368: The object.__init__() and object.__new__() methods are
7898 now stricter in rejecting excess arguments. The only time when
7899 either allows excess arguments is when it is not overridden and the
7900 other one is. For backwards compatibility, when both are
7901 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007902 warning later). Also, type.__init__() insists on the same signature
7903 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00007905- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7906 object to complex using its __complex__() method before falling back
7907 to the __float__() method. Therefore, the functions in the cmath
7908 module now can operate on objects that define a __complex__()
7909 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00007927- Bug #1678647: write a newline after printing an exception in any
7928 case, even when converting the value to a string failed.
7929
Georg Brandl871f1bc2007-03-12 13:17:36 +00007930- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007931 its argument, if it exists. If not, it will work like before. This
7932 allows customizing the output of dir() in the presence of a
7933 __getattr__().

7943 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00007944
Georg Brandlaa2321b2007-03-07 00:40:28 +00007945- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007946 makes the filenames the warning module prints much more sensible
7947 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00007948

Georg Brandl0fca97a2007-03-05 22:28:08 +00007960- Patch #1674228: when assigning a slice (old-style), check for the
7961 sq_ass_slice instead of the sq_slice slot.
7962
Georg Brandl3ee81df2008-05-17 18:14:43 +00007963- When printing an unraisable error, don't print exceptions. before

7974 created a weakref on itself during a __del__ call for new-style
7975 classes (classic classes still have the bug).

Georg Brandl2c1375c2006-10-12 11:27:59 +00008015- Bug #1545497: when given an explicit base, int() did ignore NULs
8016 embedded in the string to convert.
8017
Georg Brandl846f73a2006-10-08 07:11:54 +00008018- Bug #1569998: break inside a try statement (outside a loop) is now

Neal Norwitzdac090d2006-09-05 03:53:08 +00008065- Bug #1520864: unpacking singleton tuples in list comprehensions and
Georg Brandl3ee81df2008-05-17 18:14:43 +00008066 generator expressions (x for x, in ... ) works again. Fixing this
8067 problem required changing the .pyc magic number. This means that
8068 .pyc files generated before 2.5c2 will be regenerated.

Guido van Rossum8bc09652008-02-21 18:18:37 +00008107- Removed uses of dict.has_key() from distutils, and uses of

8590 TestCase and TestSuite subclasses (not instances) are no longer

8863 longer than 3 bytes.
Georg Brandl27562782006-10-27 20:39:43 +00008864
Georg Brandl3ee81df2008-05-17 18:14:43 +00008865- The implementation of UnicodeError objects has been simplified
8866 (start and end attributes are now stored directly as Py_ssize_t
8867 members).

Georg Brandl3ee81df2008-05-17 18:14:43 +00008869- Issue #829951: In the smtplib module, SMTP.starttls() now complies
8870 with RFC 3207 and forgets any knowledge obtained from the server not
8871 obtained from the TLS negotiation itself. Patch contributed by Bill
8872 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00008873
Georg Brandl3ee81df2008-05-17 18:14:43 +00008874- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00008875 that the SMTP.starttls() caller no longer needs to call ehlo()
8876 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00008877 does not claim to support starttls. Adds the
8878 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
8879 Fenner.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008921- Patch #976880: ``mmap`` objects now have an ``rfind`` method that
Andrew M. Kuchling5c60bfc2008-01-19 18:18:41 +00008922 works as expected. ``mmap.find`` also takes an optional ``end``
8923 parameter.
8924
Georg Brandl3ee81df2008-05-17 18:14:43 +00008925- _winreg's HKEY object has gained __enter__ and __exit__ methods to

8948 contents before adding elements from the iterable. This fix brings
8949 the behavior into line with that for list.__init__().
Raymond Hettingeradf9ffd2007-12-13 00:08:37 +00008950
Georg Brandl3ee81df2008-05-17 18:14:43 +00008951- Added wide char functions to msvcrt module: getwch, getwche, putwch

8957
Georg Brandl3ee81df2008-05-17 18:14:43 +00008958- Marshal.dumps() now expects exact type matches for int, long, float,
8959 complex, tuple, list, dict, set, and frozenset. Formerly, it would
8960 silently miscode subclasses of those types. Now, it raises a
8961 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00008962

Georg Brandl3ee81df2008-05-17 18:14:43 +00008977 time so that opening a database previously created with the DB_DUP
8978 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8979 opens. Specifically: dictionary assignment to a DB object will
8980 replace all values for a given key when the database allows
8981 duplicate values. DB users should use DB.put(k, v) when they want
8982 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00008983

8989 characters with ASCII value less than 32. Also, it correctly quotes
8990 dots only if they occur on a single line, as opposed to the previous
8991 behavior of quoting dots if they are the second character of any
8992 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00008993

9022 negative numbers, per the underlying C implementation.
Guido van Rossumbb2cc692007-01-14 17:03:32 +00009023

Georg Brandl3ee81df2008-05-17 18:14:43 +00009407- Removed the macfs module. It had been deprecated since Python 2.5.
9408 This lead to the deprecation of macostools.touched() as it relied
9409 solely on macfs and was a no-op under OS X.
