1121 32-bit-only installer Pythons on systems with Xcode 4 (currently
1122 OS X 10.8, 10.7, and optionally 10.6).
1123 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1124 * Since Xcode 4 removes ppc support, extension module builds now
1125 check for ppc compiler support and by default remove ppc and
1126 ppc64 archs when they are not available.
1127 * Extension module builds now revert to using system installed
1128 headers and libs (/usr and /System/Library) if the SDK used
1129 to build the interpreter is not installed or has moved.
1130 * Try to avoid building extension modules with deprecated
1131 and problematic Apple llvm-gcc compiler. If original compiler
1132 is not available, use clang instead by default.

Mark Dickinsondbbed042011-09-19 16:38:08 +01001483- Issue #12973: Fix overflow checks that invoked undefined behaviour in
1484 int.__pow__. These overflow checks were causing int.__pow__ to produce
1485 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +01001486 compiler optimizing the check away. Also fix similar overflow checks
1487 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
1488 bugs caused test failures with recent versions of Clang.

Florent Xiclunac2279652012-02-12 14:49:03 +01001556- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01001557 has left two versions of customize_compiler, the original in
1558 distutils.sysconfig and another copy in distutils.ccompiler, with some

1561 is the case in 3.x.

Ned Deily0d0ea482012-02-10 12:59:06 +01001563- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1564 Distutils-based packages with C extension modules may fail because
1565 Apple has removed gcc-4.2, the version used to build python.org
1566 64-bit/32-bit Pythons. If the user does not explicitly override
1567 the default C compiler by setting the CC environment variable,
1568 Distutils will now attempt to compile extension modules with clang
1569 if gcc-4.2 is required but not found. Also as a convenience, if
1570 the user does explicitly set CC, substitute its value as the default
1571 compiler in the Distutils LDSHARED configuration variable for OS X.
1572 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1573 SDK, neither of which are available in Xcode 4. This change does not
1574 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001824- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1825 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1826 interpreter process. This could cause failures in non-Distutils subprocesses
1827 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02001828 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07001829 deployment target only in the environment of each build subprocess. It is
1830 still possible to globally override the default by setting
1831 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1832 greater or equal to the default value, the value with which the interpreter
1833 was built.

1862 updating the check interval, so if the user decreases the check interval,
1863 the ticker doesn't have to wind down to zero from the old starting point
1864 before the new interval takes effect. And if the user increases the
1865 interval, it makes sure the new limit takes effect right away rather have an
1866 early task switch before recognizing the new interval.

2845
Raymond Hettinger20397532010-09-12 02:11:45 +00002846- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
2847 This prevents user-created self-referencing ordered dictionaries from
2848 becoming permanently uncollectable GC garbage. The downside is that
2849 removing __del__ means that the internal doubly-linked list has to wait for
2850 GC collection rather than freeing memory immediately when the refcnt drops
2851 to zero.

2856

2859 to fetch the original errno, or to filter timeout errors. Now the
2860 original error is re-raised.

3309
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003310- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3311 start byte and the continuation byte(s) are now considered invalid, instead
3312 of the number of bytes specified by the start byte.
3313 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3314 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3315 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
3316 Previous versions returned a single u'\ufffd'.

3320 arises from the "Overriding __eq__ blocks inheritance ..." warning
3321 when turned into an exception: in this case the exception simply
3322 gets ignored.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00003324- Issue #8748: Fix two issues with comparisons between complex and integer
3325 objects. (1) The comparison could incorrectly return True in some cases
3326 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
3327 (2) The comparison raised an OverflowError for large integers, leading
3328 to unpredictable exceptions when combining integers and complex objects
3329 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +00003331- Issue #5211: Implicit coercion for the complex type is now completely

Georg Brandlba83f822010-03-14 09:50:54 +00004209 file position when calling `truncate()`. It would previously change the file
4210 position to the given argument, which goes against the tradition of

4214 class used to represent files stored inside an archive. The new
4215 implementation is significantly faster and can be wrapped in a
4216 ``io.BufferedReader`` object for more speedups. It also solves an issue
4217 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

4306-----------------
4307
Georg Brandlba83f822010-03-14 09:50:54 +00004308- The ``__complex__()`` method is now looked up on the class of instances to
4309 make it consistent with other special methods.

4313
Mark Dickinson1b34d252010-01-01 17:27:30 +00004314- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004315 DeprecationWarning when passed a float argument where an integer was expected.
4316 These functions and methods now raise TypeError instead. The majority of the
4317 effects of this change are in the extension modules, but some core functions
4318 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4319 and many unicode/str methods.

4333 of integers: the result of a/b is now correctly rounded for ints a and b (at
4334 least on IEEE 754 platforms), and in particular does not depend on the
4335 internal representation of a long.

4343
Georg Brandlba83f822010-03-14 09:50:54 +00004344 These executables now work properly with the arch(1) command: ``arch -ppc
4345 python`` will start a universal binary version of python in PPC mode (unlike

Georg Brandlba83f822010-03-14 09:50:54 +00004431- Issue #5080: The argument parsing functions ``PyArg_ParseTuple()``,
4432 ``PyArg_ParseTupleAndKeywords()``, ``PyArg_VaParse()``,
4433 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept
4434 float arguments for integer format codes (other than 'L'): previously an
4435 attempt to pass a float resulted in a DeprecationWarning; now it gives a
4436 TypeError. For the 'L' format code (which previously had no warning) there is
4437 now a DeprecationWarning.

4485 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
4486 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00004487
Georg Brandlba83f822010-03-14 09:50:54 +00004488- Remove switch from "%f" formatting to "%g" formatting for floats larger than
4489 1e50 in absolute value.

Georg Brandlba83f822010-03-14 09:50:54 +00004491- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
4492 1e-100 used to raise OverflowError, but now gives the requested 120
4493 significant digits instead.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00004501
Georg Brandlba83f822010-03-14 09:50:54 +00004502- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4503 decimal string that's guaranteed to round back to x under correct rounding
4504 (with round-half-to-even rounding mode). Previously it gave a string based on
4505 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4506 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4507 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004508
Georg Brandlba83f822010-03-14 09:50:54 +00004509- Issue #7117: On almost all platforms: float-to-string and string-to-float
4510 conversions within Python are now correctly rounded. Places these conversions
4511 occur include: str for floats and complex numbers; the float and complex
4512 constructors; old-style and new-style numeric formatting; serialization and
4513 deserialization of floats and complex numbers using marshal, pickle and json;
4514 parsing of float and imaginary literals in Python code; Decimal-to-float
4515 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004516
Georg Brandlba83f822010-03-14 09:50:54 +00004517 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4518 providing correctly-rounded strtod and dtoa C functions. This code is
4519 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4520 the C compiler. There may be a small number of platforms on which correct
4521 operation of this code cannot be guaranteed, so the code is not used: notably,
4522 this applies to platforms where the C double format is not IEEE 754 binary64,
4523 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4524 and Python's configure script is unable to determine how to change the FPU
4525 precision. On these platforms conversions use the platform strtod and dtoa,
4526 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004527
Georg Brandlba83f822010-03-14 09:50:54 +00004528- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4529 uses the correctly-rounded string <-> float conversions described above (when
4530 available), and so produces correctly rounded results that will display nicely
4531 under the float repr. There are two related small changes: (1) round now
4532 accepts any class with an ``__index__()`` method for its second argument (but
4533 no longer accepts floats for the second argument), and (2) an excessively
4534 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4535 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00004677
Georg Brandlba83f822010-03-14 09:50:54 +00004678 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
4679 (2) parsing of strings representing infinities and nans was locale aware; and
4680 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00004682- Issue #5920: For ``float.__format__()``, change the behavior with the empty
4683 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
4684 but with at least one decimal point and with a default precision
4685 of 12. Previously, the behavior the same but with a default precision of 6.
4686 This more closely matches ``str()``, and reduces surprises when adding
4687 alignment flags to the empty presentation type. This also affects the new
4688 complex.__format__ in the same way.
4689
4690- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

6121 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
6122 neither __int__ nor __long__, TypeError used to be raised (with a

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00006319- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
6320
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006321- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6322 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6323 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6324 ``printf`` function, whereas PyString_FromFormat has an independent
6325 implementation and uses "%zd" on all platforms for size_t values.
6326 This makes a difference on win64, where ``printf`` needs "%Id" to display
6327 64bit values.
6328
Benjamin Peterson97179b02008-09-09 20:55:01 +00006329- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
6330 error.
6331
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00006332- Issue #3777: long() applied to a float object now always return a long
6333 object; previously an int would be returned for small values. the __long__
6334 method is allowed to return either an int or a long, but the behaviour of
6335 float objects should not change to respect backward compatibility.
6336
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00006337- Issue #3751: str.rpartition would perform a left-partition when called with
6338 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +00006343 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006344 was correctly parsed but parsing of subsequent arguments failed.
6345
Vinay Sajip35e3b032008-09-01 14:33:59 +00006346- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006347 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6348 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6349 when given a tuple of classes as second argument, were looking up
6350 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6351 type object.
6352
Neal Norwitz18aa3882008-08-24 05:04:52 +00006353- Fix crashes on memory allocation failure found with failmalloc.

Brett Cannon1eaf0742008-09-02 01:25:16 +00006422 warnings.catch_warnings() along with some API cleanup. Expanding the tests
6423 for catch_warnings() also led to an improvement in the raising of a

6496-----------------
6497
Guido van Rossumf8402962008-08-20 15:01:50 +00006498- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6499 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6500 extensions do not automatically benefit from the class attribute
6501 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6502 to their tp_flags field if they care. This is a backwards
6503 compatibility feature; in 3.0, all types will use the cache by
6504 default.
6505
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006506- Keyword arguments can now follow starred arguments. (``f(a, *args,
6507 keyword=23)`` is now valid syntax.)
6508
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006509- ctypes function pointers that are COM methods have a boolean True
6510 value again.
6511
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006512- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6513 by denying s# to parse objects that have a releasebuffer procedure,
6514 and introducing s*.
6515
Georg Brandl1e13ea92008-08-11 09:07:59 +00006516- Issue #3537: Fix an assertion failure when an empty but presized dict
6517 object was stored in the freelist.
6518
Mark Dickinsonb6467572008-08-04 21:30:09 +00006519- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6520 ValueError consistently across platforms.
6521
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006522- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6523 (64bit Unix, for example), unichr() would truncate its argument and return
6524 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6525
Neal Norwitze7d8be82008-07-31 17:17:14 +00006526- Apply security patches from Apple.
6527
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006528- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6529 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6530
Antoine Pitrou92f82162008-07-25 22:22:08 +00006531- Issue #1819: function calls with several named parameters are now on
6532 average 35% faster (as measured by pybench).
6533
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006534- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6535 the python debugger steps into a class statement: the free variables (local
6536 variables defined in an outer scope) would be deleted from the outer scope.
6537
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006538- Issue #2620: Overflow checking when allocating or reallocating memory
6539 was not always being done properly in some python types and extension
6540 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6541 all been updated to perform better checks and places in the code that
6542 would previously leak memory on the error path when such an allocation
6543 failed have been fixed.

6549
Benjamin Petersone977ad42008-08-20 01:42:01 +00006550- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of

6552
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006553- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6554 version reported by these tools does not necessarily follow the python
6555 version numbering scheme, so the module is less strict when parsing it.
6556
Nick Coghlanf70385a2008-08-18 12:42:46 +00006557- Issue #2235: Added Py3k warnings for types which will become unhashable
6558 under the stricter __hash__ inheritance rules in 3.0. Several types
6559 which did not meet the rules for hash invariants and were already
6560 unhashable in 3.0 have now been explicitly flagged as unhashable in
6561 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6562 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6563

6619 the reload() built-in has been removed.
6620
Brett Cannon7e30b672008-08-04 21:52:25 +00006621- Changed code in the following modules/packages to remove warnings raised

Antoine Pitroude781a42008-08-09 12:43:23 +00006633 asking for a specific length. This problem only affected files opened
6634 using the new "io" module, not the built-in open() function.

6677
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00006678- Issue #643841: The language reference now provides more detailed
6679 coverage of the lookup process for special methods. The disclaimers
6680 regarding lack of coverage of new-style classes have also been
6681 removed, since the coverage is now fairly reasonable.

6685================================
6686
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006687*Release date: 17-Jul-2008*
6688
Raymond Hettingere3ae6552008-06-20 04:18:15 +00006689Core and Builtins
6690-----------------
6691
Georg Brandl3e483f62008-07-16 22:57:41 +00006692- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6693 its methods now allow for items objects that can be converted to
6694 an integer using operator.index().
6695
Mark Dickinson64b7e502008-07-16 09:40:03 +00006696- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6697 produced a ValueError instead of giving the correct float.
6698
Eric Smitha5fa5a22008-07-16 00:11:49 +00006699- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6700 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6701
Mark Dickinson7103aa42008-07-15 19:08:33 +00006702- Issue #3008: the float type has a new instance method 'float.hex'
6703 and a new class method 'float.fromhex' to convert floating-point
6704 numbers to and from hexadecimal strings, respectively.
6705
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006706- Issue #2235: __hash__ is once again inherited by default. To allow
6707 collections.Hashable to remain meaningful in the presence of the
6708 default hash implementation (object.__hash__), it is now possible
6709 to explicit block inheritance of hash by setting __hash__=None at
6710 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6711 level.
6712
Nick Coghlanb028f502008-07-13 14:52:36 +00006713- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6714 the parent module cannot be found while performing an absolute import.
6715 This means that an incorrectly defined __package__ attribute will
6716 now only prevent relative imports in that module rather than causing
6717 all imports from that module to fail.
6718
Nick Coghlan14ff9942008-07-08 14:21:42 +00006719- Issue #2517: Allow unicode messages in Exceptions again by correctly
6720 bypassing the instance dictionary when looking up __unicode__ on
6721 new-style classes.
6722
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00006723- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
6724 set to a custom object whose write() method happens to install
6725 another file in sys.stdout.
6726
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00006727- Issue #3088: Corrected a race condition in classes derived from
6728 threading.local: the first member set by a thread could be saved in
6729 another thread's dictionary.
6730
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006731- Issue #3004: Minor change to slice.indices(): the start and stop
6732 arguments are now treated identically, making the behaviour easier
6733 to describe and understand. For example, slice(None, -10,
6734 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6735 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6736 10, -1).
6737
Georg Brandl278fc502008-07-19 12:46:12 +00006738- Issue #3219: Calling a function with repeated keyword arguments,
6739 f(a=2, a=23), would not cause a syntax error. This was a regression
6740 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00006741
Georg Brandl278fc502008-07-19 12:46:12 +00006742- Issue #2862: Make int and float freelist management consistent with
6743 other freelists. Changes their CompactFreeList apis into
6744 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00006745

Thomas Heller57adf222008-08-14 19:10:48 +00006749- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
6750 api functions without holding the GIL, which could lead to a fatal
6751 error when they failed.
6752
Martin v. Löwisaabf4042008-08-02 07:20:25 +00006753- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

6762 ForkingPickler.register() to resolve conflict with ctypes.
6763
Vinay Sajip51e65192008-07-18 09:01:10 +00006764- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

6767 a valid dlerror() message.
6768
Thomas Heller2bad6572008-07-15 17:19:50 +00006769- Issue #3258: Fixed a crash when a ctypes POINTER type to an

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006776- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00006777
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006778- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
6779 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006780 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006781 content-length. The problem had been corrected in the 2.4 branch, but never
6782 merged into trunk.
6783

Nick Coghlanc060b0e2008-07-02 13:09:19 +00006797- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
6798 handling is now the same as that of other special attributes like __name__).
6799
Brett Cannon8bb8fa52008-07-02 01:57:08 +00006800- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
6801 removal in Python 3.0 in favor of urllib2.urlopen().

Ronald Oussoren5640ce22008-06-05 12:58:24 +00007188- On MacOS X it is now possible to install the framework in 64-bit
7189 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00007190 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007191
7192 This is controlled by the configure argument ``--with-universal-archs``:
7193
7194 - ``--with-universal-archs=all``: install 4-way universal
7195
7196 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7197
7198 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7199
7200 This option should be used in combination with ``--enable-universalsdk=``.
7201
7202 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 +00007252- Issue #1631171: Re-implement the 'warnings' module in C (the
7253 original Python code has been kept as backup). This will allow for
7254 using the 'warning's machinery in such places as the parser where
7255 use of pure Python code is not possible. Both the ``showarning()``
7256 and ``formatwarning()`` gain an optional 'line' argument which is
7257 not called by default for backwards-compatibility reasons. Setting
7258 ``warnings.showwarning()`` to an implementation that lacks support
7259 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007322- Issue #2550: The approach used by client/server code for obtaining
7323 ports to listen on in network-oriented tests has been refined in an
7324 effort to facilitate running multiple instances of the entire
7325 regression test suite in parallel without issue.
7326 test_support.bind_port() has been fixed such that it will always
7327 return a unique port -- which wasn't always the case with the
7328 previous implementation, especially if socket options had been set
7329 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7330 new implementation of bind_port() will actually raise an exception
7331 if it is passed an AF_INET/SOCK_STREAM socket with either the
7332 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7333 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7334 the socket it's been passed. This currently only applies to
7335 Windows. This option prevents any other sockets from binding to the
7336 host/port we've bound to, thus removing the possibility of the
7337 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7338 when a second SOCK_STREAM socket binds and accepts to a host/port
7339 that's already been bound by another socket. The optional preferred
7340 port parameter to bind_port() has been removed. Under no
7341 circumstances should tests be hard coding ports!
7342
7343 test_support.find_unused_port() has also been introduced, which will
7344 pass a temporary socket object to bind_port() in order to obtain an
7345 unused port. The temporary socket object is then closed and
7346 deleted, and the port is returned. This method should only be used
7347 for obtaining an unused port in order to pass to an external program
7348 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7349 a parameter to a server-oriented class that doesn't give you direct
7350 access to the underlying socket used.
7351
7352 Finally, test_support.HOST has been introduced, which should be used
7353 for the host argument of any relevant socket calls (i.e. bind and
7354 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007355
7356 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007357 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007358 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7359 test_asynchat and test_socket_ssl.
7360
Georg Brandl3ee81df2008-05-17 18:14:43 +00007361 It is now possible for multiple instances of the regression test
7362 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00007416- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00007417 \Uxxxxxxxx did not accept values outside the Basic Multilingual
7418 Plane. This affected raw unicode literals and the
7419 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
7420 this case, like normal unicode literals and the 'unicode-escape'
7421 codec.

7645 Python 2.6 builtins. The expected usage of the future_builtins
7646 module is:
7647 from future_builtins import hex, oct
7648
Eric Smith7ef40bf2008-02-20 23:34:22 +00007649- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7650 exponents for exponents with absolute value < 100. Follows C99
7651 standard. This is a change on Windows, which would use 3 digits.
7652 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7653 so that any alterations it does to the resulting string will be
7654 available in stringlib/formatter.h (for float.__format__).
7655
Eric Smith5a3c1352008-02-19 13:21:56 +00007656- Implemented PEP 3101, Advanced String Formatting. This adds a new
7657 builtin format(); a format() method for str and unicode; a
7658 __format__() method to object, str, unicode, int, long, float, and
7659 datetime; the class string.Formatter; and the C API
7660 PyObject_Format().
7661
Georg Brandl3ee81df2008-05-17 18:14:43 +00007662- Fixed several potential crashes, all caused by specially crafted
7663 __del__ methods exploiting objects in temporarily inconsistent
7664 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00007665
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007666- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00007667 prevent a possible crash: an Abstract Base Class would try to access
7668 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00007669

Georg Brandl3ee81df2008-05-17 18:14:43 +00007673- Clear all free lists during a gc.collect() of the highest generation
7674 in order to allow pymalloc to free more arenas. Python may give back
7675 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007676
Georg Brandl3ee81df2008-05-17 18:14:43 +00007677- Issue #2045: Fix an infinite recursion triggered when printing a
7678 subclass of collections.defaultdict, if its default_factory is set
7679 to a bound method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007707- Patch #1473257: generator objects gain a gi_code attribute. This is
7708 the same object as the func_code attribute of the function that
7709 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007710
Georg Brandl3ee81df2008-05-17 18:14:43 +00007711- Issue #1920: "while 0" statements were completely removed by the
7712 compiler, even in the presence of an "else" clause, which is
7713 supposed to be run when the condition is false. Now the compiler
7714 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007715
Guido van Rossumeead05f2008-01-24 18:21:02 +00007716- A few crashers fixed: weakref_in_del.py (issue #1377858);

7723
Georg Brandl3ee81df2008-05-17 18:14:43 +00007724- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007725 several extension methods and modules do not work without unicode
7726 support.
7727
Georg Brandl26543b12008-01-21 18:36:51 +00007728- Issue #1882: when compiling code from a string, encoding cookies in the

7732
Georg Brandl6caad7d2008-01-26 14:19:22 +00007733- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007734 added.
7735
Christian Heimesc94e2b52008-01-14 04:13:37 +00007736- sys.float_info / PyFloat_GetInfo: The floating point information
7737 object was converted from a dict to a specialized structseq object.
7738
Georg Brandl3ee81df2008-05-17 18:14:43 +00007739- Patch #1816: Added sys.flags structseq. It exposes the status of
7740 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007741
Georg Brandl3ee81df2008-05-17 18:14:43 +00007742- Objects/structseq.c: Implemented new structseq representation. The
7743 patch makes structseqs (e.g. the return value of os.stat) more
7744 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007745
Georg Brandl3ee81df2008-05-17 18:14:43 +00007746- Patch #1700288: added a type attribute cache that caches method
7747 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00007748
Neal Norwitz3fc15b82008-01-10 05:42:58 +00007749- Bug #1776: __import__() no longer accepts filenames on any platform.

7755 envvar and sys.dont_write_bytecode attribute. All these can be set
7756 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007757
Georg Brandl3ee81df2008-05-17 18:14:43 +00007758- Improve some exception messages when Windows fails to load an
7759 extension module. Now we get for example '%1 is not a valid Win32
7760 application' instead of 'error code 193'.

7817
Georg Brandl21e99f42010-03-07 15:23:59 +00007818- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007819 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7820 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007821
Georg Brandl3ee81df2008-05-17 18:14:43 +00007822- Issue #1686386: Tuple's tp_repr did not take into account the
7823 possibility of having a self-referential tuple, which is possible
7824 from C code. Nor did object's tp_str consider that a type's tp_str
7825 could do something that could lead to an inifinite recursion.
7826 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7827 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007828
Georg Brandl3ee81df2008-05-17 18:14:43 +00007829- Issue #1164: It was possible to trigger deadlock when using the
7830 'print' statement to write to a file since the GIL was not released
7831 as needed. Now PyObject_Print() does the right thing along with
7832 various tp_print implementations of the built-in types and those in
7833 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007834

Georg Brandl3ee81df2008-05-17 18:14:43 +00007843 PyObject_Call() never calling back out to Python code to trigger
7844 recursion depth updates/checks. Required the creation of a static
7845 RuntimeError instance in case normalizing an exception put the
7846 recursion check value past its limit. Fixes crashers

Raymond Hettinger4db5fe92007-04-12 04:10:00 +00007886- Request #1193128: str.translate() now allows a None argument for
7887 translations that only remove characters without re-mapping the
7888 remaining characters.
7889
Georg Brandl5cb76c12007-03-21 09:00:39 +00007890- Patch #1682205: a TypeError while unpacking an iterable is no longer
7891 masked by a generic one with the message "unpack non-sequence".

7894
Guido van Rossum143b5642007-03-23 04:58:42 +00007895- Bug #1683368: The object.__init__() and object.__new__() methods are
7896 now stricter in rejecting excess arguments. The only time when
7897 either allows excess arguments is when it is not overridden and the
7898 other one is. For backwards compatibility, when both are
7899 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007900 warning later). Also, type.__init__() insists on the same signature
7901 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00007903- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7904 object to complex using its __complex__() method before falling back
7905 to the __float__() method. Therefore, the functions in the cmath
7906 module now can operate on objects that define a __complex__()
7907 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00007925- Bug #1678647: write a newline after printing an exception in any
7926 case, even when converting the value to a string failed.
7927
Georg Brandl871f1bc2007-03-12 13:17:36 +00007928- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007929 its argument, if it exists. If not, it will work like before. This
7930 allows customizing the output of dir() in the presence of a
7931 __getattr__().

7941 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00007942
Georg Brandlaa2321b2007-03-07 00:40:28 +00007943- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007944 makes the filenames the warning module prints much more sensible
7945 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00007946

7959 sq_ass_slice instead of the sq_slice slot.
7960
Georg Brandl3ee81df2008-05-17 18:14:43 +00007961- When printing an unraisable error, don't print exceptions. before
7962 the name. This duplicates the behavior whening normally printing
7963 exceptions.

Georg Brandl2c1375c2006-10-12 11:27:59 +00008013- Bug #1545497: when given an explicit base, int() did ignore NULs
8014 embedded in the string to convert.
8015
Georg Brandl846f73a2006-10-08 07:11:54 +00008016- Bug #1569998: break inside a try statement (outside a loop) is now

Neal Norwitzdac090d2006-09-05 03:53:08 +00008063- Bug #1520864: unpacking singleton tuples in list comprehensions and
Georg Brandl3ee81df2008-05-17 18:14:43 +00008064 generator expressions (x for x, in ... ) works again. Fixing this
8065 problem required changing the .pyc magic number. This means that
8066 .pyc files generated before 2.5c2 will be regenerated.

Guido van Rossum8bc09652008-02-21 18:18:37 +00008105- Removed uses of dict.has_key() from distutils, and uses of

8588 TestCase and TestSuite subclasses (not instances) are no longer

8861 longer than 3 bytes.
Georg Brandl27562782006-10-27 20:39:43 +00008862
Georg Brandl3ee81df2008-05-17 18:14:43 +00008863- The implementation of UnicodeError objects has been simplified
8864 (start and end attributes are now stored directly as Py_ssize_t
8865 members).

Georg Brandl3ee81df2008-05-17 18:14:43 +00008867- Issue #829951: In the smtplib module, SMTP.starttls() now complies
8868 with RFC 3207 and forgets any knowledge obtained from the server not
8869 obtained from the TLS negotiation itself. Patch contributed by Bill
8870 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00008871
Georg Brandl3ee81df2008-05-17 18:14:43 +00008872- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00008873 that the SMTP.starttls() caller no longer needs to call ehlo()
8874 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00008875 does not claim to support starttls. Adds the
8876 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
8877 Fenner.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008919- Patch #976880: ``mmap`` objects now have an ``rfind`` method that
Andrew M. Kuchling5c60bfc2008-01-19 18:18:41 +00008920 works as expected. ``mmap.find`` also takes an optional ``end``
8921 parameter.
8922

8946 contents before adding elements from the iterable. This fix brings
8947 the behavior into line with that for list.__init__().
Raymond Hettingeradf9ffd2007-12-13 00:08:37 +00008948
Georg Brandl3ee81df2008-05-17 18:14:43 +00008949- Added wide char functions to msvcrt module: getwch, getwche, putwch

8955
Georg Brandl3ee81df2008-05-17 18:14:43 +00008956- Marshal.dumps() now expects exact type matches for int, long, float,
8957 complex, tuple, list, dict, set, and frozenset. Formerly, it would
8958 silently miscode subclasses of those types. Now, it raises a
8959 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00008960

Georg Brandl3ee81df2008-05-17 18:14:43 +00008975 time so that opening a database previously created with the DB_DUP
8976 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8977 opens. Specifically: dictionary assignment to a DB object will
8978 replace all values for a given key when the database allows
8979 duplicate values. DB users should use DB.put(k, v) when they want
8980 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00008981

8987 characters with ASCII value less than 32. Also, it correctly quotes
8988 dots only if they occur on a single line, as opposed to the previous
8989 behavior of quoting dots if they are the second character of any
8990 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00008991

9020 negative numbers, per the underlying C implementation.
Guido van Rossumbb2cc692007-01-14 17:03:32 +00009021

Georg Brandl3ee81df2008-05-17 18:14:43 +00009405- Removed the macfs module. It had been deprecated since Python 2.5.
9406 This lead to the deprecation of macostools.touched() as it relied
9407 solely on macfs and was a no-op under OS X.
