Ned Deily18fae3f2013-01-31 01:24:55 -0800875- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
876 In particular, fix extension module build failures when trying to use
877 32-bit-only installer Pythons on systems with Xcode 4 (currently
878 OS X 10.8, 10.7, and optionally 10.6).
879 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
880 * Since Xcode 4 removes ppc support, extension module builds now
881 check for ppc compiler support and by default remove ppc and
882 ppc64 archs when they are not available.
883 * Extension module builds now revert to using system installed
884 headers and libs (/usr and /System/Library) if the SDK used
885 to build the interpreter is not installed or has moved.
886 * Try to avoid building extension modules with deprecated
887 and problematic Apple llvm-gcc compiler. If original compiler
888 is not available, use clang instead by default.

Florent Xiclunac2279652012-02-12 14:49:03 +01001247- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01001248 has left two versions of customize_compiler, the original in
1249 distutils.sysconfig and another copy in distutils.ccompiler, with some
1250 parts of distutils calling one and others using the other.
1251 Complete the revert back to only having one in distutils.sysconfig as
1252 is the case in 3.x.
1253
Ned Deily0d0ea482012-02-10 12:59:06 +01001254- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1255 Distutils-based packages with C extension modules may fail because
1256 Apple has removed gcc-4.2, the version used to build python.org
1257 64-bit/32-bit Pythons. If the user does not explicitly override
1258 the default C compiler by setting the CC environment variable,
1259 Distutils will now attempt to compile extension modules with clang
1260 if gcc-4.2 is required but not found. Also as a convenience, if
1261 the user does explicitly set CC, substitute its value as the default
1262 compiler in the Distutils LDSHARED configuration variable for OS X.
1263 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1264 SDK, neither of which are available in Xcode 4. This change does not
1265 attempt to override settings to support their use with Xcode 4.)

1350 raised when the wrapped raw file is non-blocking and the write would block.

Ned Deily87e82bb2011-06-28 19:52:59 -07001538- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1539 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1540 interpreter process. This could cause failures in non-Distutils subprocesses
1541 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02001542 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07001543 deployment target only in the environment of each build subprocess. It is
1544 still possible to globally override the default by setting
1545 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1546 greater or equal to the default value, the value with which the interpreter
1547 was built.

1574
Barry Warsawc5643282011-07-19 17:06:30 -04001575- sys.setcheckinterval() now updates the current ticker count as well as
1576 updating the check interval, so if the user decreases the check interval,
1577 the ticker doesn't have to wind down to zero from the old starting point
1578 before the new interval takes effect. And if the user increases the
1579 interval, it makes sure the new limit takes effect right away rather have an
1580 early task switch before recognizing the new interval.

2530
Raymond Hettinger20397532010-09-12 02:11:45 +00002531- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
2532 This prevents user-created self-referencing ordered dictionaries from
2533 becoming permanently uncollectable GC garbage. The downside is that
2534 removing __del__ means that the internal doubly-linked list has to wait for
2535 GC collection rather than freeing memory immediately when the refcnt drops
2536 to zero.

2544 to fetch the original errno, or to filter timeout errors. Now the
2545 original error is re-raised.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00002995- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
2996 start byte and the continuation byte(s) are now considered invalid, instead
2997 of the number of bytes specified by the start byte.
2998 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
2999 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3000 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00003009- Issue #8748: Fix two issues with comparisons between complex and integer
3010 objects. (1) The comparison could incorrectly return True in some cases
3011 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
3012 (2) The comparison raised an OverflowError for large integers, leading
3013 to unpredictable exceptions when combining integers and complex objects
3014 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +00003016- Issue #5211: Implicit coercion for the complex type is now completely

3397 with a non-empty format string. This is an effort to future-proof user
3398 code. If a derived class does not currently implement __format__ but later
3399 adds its own __format__, it would most likely break user code that had

Georg Brandlba83f822010-03-14 09:50:54 +00003887 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00003888 Also, raise ValueError rather than TypeError when an unknown TIPC address
3889 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003893- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00003894 file position when calling `truncate()`. It would previously change the file
3895 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003896 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
3897
Georg Brandlba83f822010-03-14 09:50:54 +00003898- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
3899 class used to represent files stored inside an archive. The new
3900 implementation is significantly faster and can be wrapped in a
3901 ``io.BufferedReader`` object for more speedups. It also solves an issue
3902 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
3903 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +00003913- Issue #7748: Since unicode values are supported for some metadata options in
3914 Distutils, the DistributionMetadata get_* methods will now return an utf-8
3915 encoded string for them. This ensures that the upload and register commands
3916 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00003993- The ``__complex__()`` method is now looked up on the class of instances to
3994 make it consistent with other special methods.

3998
Mark Dickinson1b34d252010-01-01 17:27:30 +00003999- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004000 DeprecationWarning when passed a float argument where an integer was expected.
4001 These functions and methods now raise TypeError instead. The majority of the
4002 effects of this change are in the extension modules, but some core functions
4003 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4004 and many unicode/str methods.

4018 of integers: the result of a/b is now correctly rounded for ints a and b (at
4019 least on IEEE 754 platforms), and in particular does not depend on the
4020 internal representation of a long.

4028
Georg Brandlba83f822010-03-14 09:50:54 +00004029 These executables now work properly with the arch(1) command: ``arch -ppc
4030 python`` will start a universal binary version of python in PPC mode (unlike
4031 previous releases).

4171 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00004172

Georg Brandlba83f822010-03-14 09:50:54 +00004187- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4188 decimal string that's guaranteed to round back to x under correct rounding
4189 (with round-half-to-even rounding mode). Previously it gave a string based on
4190 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4191 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4192 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004193
Georg Brandlba83f822010-03-14 09:50:54 +00004194- Issue #7117: On almost all platforms: float-to-string and string-to-float
4195 conversions within Python are now correctly rounded. Places these conversions
4196 occur include: str for floats and complex numbers; the float and complex
4197 constructors; old-style and new-style numeric formatting; serialization and
4198 deserialization of floats and complex numbers using marshal, pickle and json;
4199 parsing of float and imaginary literals in Python code; Decimal-to-float
4200 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004201
Georg Brandlba83f822010-03-14 09:50:54 +00004202 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4203 providing correctly-rounded strtod and dtoa C functions. This code is
4204 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4205 the C compiler. There may be a small number of platforms on which correct
4206 operation of this code cannot be guaranteed, so the code is not used: notably,
4207 this applies to platforms where the C double format is not IEEE 754 binary64,
4208 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4209 and Python's configure script is unable to determine how to change the FPU
4210 precision. On these platforms conversions use the platform strtod and dtoa,
4211 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00004213- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4214 uses the correctly-rounded string <-> float conversions described above (when
4215 available), and so produces correctly rounded results that will display nicely
4216 under the float repr. There are two related small changes: (1) round now
4217 accepts any class with an ``__index__()`` method for its second argument (but
4218 no longer accepts floats for the second argument), and (2) an excessively
4219 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4220 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00004362
Georg Brandlba83f822010-03-14 09:50:54 +00004363 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
4364 (2) parsing of strings representing infinities and nans was locale aware; and
4365 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00004367- Issue #5920: For ``float.__format__()``, change the behavior with the empty
4368 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
4369 but with at least one decimal point and with a default precision
4370 of 12. Previously, the behavior the same but with a default precision of 6.
4371 This more closely matches ``str()``, and reduces surprises when adding
4372 alignment flags to the empty presentation type. This also affects the new
4373 complex.__format__ in the same way.
4374
4375- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

4572 file objects with closefd=False. The file descriptor is still kept open but
4573 the file object behaves like a closed file. The ``FileIO`` object also got a
4574 new readonly attribute ``closefd``.

4626 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00006001- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
6002
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006003- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6004 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6005 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6006 ``printf`` function, whereas PyString_FromFormat has an independent
6007 implementation and uses "%zd" on all platforms for size_t values.
6008 This makes a difference on win64, where ``printf`` needs "%Id" to display
6009 64bit values.
6010
Benjamin Peterson97179b02008-09-09 20:55:01 +00006011- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
6012 error.
6013
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00006014- Issue #3777: long() applied to a float object now always return a long
6015 object; previously an int would be returned for small values. the __long__
6016 method is allowed to return either an int or a long, but the behaviour of
6017 float objects should not change to respect backward compatibility.
6018
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00006019- Issue #3751: str.rpartition would perform a left-partition when called with
6020 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +00006025 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006026 was correctly parsed but parsing of subsequent arguments failed.
6027
Vinay Sajip35e3b032008-09-01 14:33:59 +00006028- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006029 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6030 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6031 when given a tuple of classes as second argument, were looking up
6032 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6033 type object.
6034
Neal Norwitz18aa3882008-08-24 05:04:52 +00006035- Fix crashes on memory allocation failure found with failmalloc.

Brett Cannon1eaf0742008-09-02 01:25:16 +00006104 warnings.catch_warnings() along with some API cleanup. Expanding the tests
6105 for catch_warnings() also led to an improvement in the raising of a

6178-----------------
6179
Guido van Rossumf8402962008-08-20 15:01:50 +00006180- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6181 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6182 extensions do not automatically benefit from the class attribute
6183 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6184 to their tp_flags field if they care. This is a backwards
6185 compatibility feature; in 3.0, all types will use the cache by
6186 default.
6187
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006188- Keyword arguments can now follow starred arguments. (``f(a, *args,
6189 keyword=23)`` is now valid syntax.)
6190
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006191- ctypes function pointers that are COM methods have a boolean True
6192 value again.
6193
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006194- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6195 by denying s# to parse objects that have a releasebuffer procedure,
6196 and introducing s*.
6197
Georg Brandl1e13ea92008-08-11 09:07:59 +00006198- Issue #3537: Fix an assertion failure when an empty but presized dict
6199 object was stored in the freelist.
6200
Mark Dickinsonb6467572008-08-04 21:30:09 +00006201- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6202 ValueError consistently across platforms.
6203
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006204- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6205 (64bit Unix, for example), unichr() would truncate its argument and return
6206 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6207
Neal Norwitze7d8be82008-07-31 17:17:14 +00006208- Apply security patches from Apple.
6209
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006210- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6211 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6212
Antoine Pitrou92f82162008-07-25 22:22:08 +00006213- Issue #1819: function calls with several named parameters are now on
6214 average 35% faster (as measured by pybench).
6215
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006216- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6217 the python debugger steps into a class statement: the free variables (local
6218 variables defined in an outer scope) would be deleted from the outer scope.
6219
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006220- Issue #2620: Overflow checking when allocating or reallocating memory
6221 was not always being done properly in some python types and extension
6222 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6223 all been updated to perform better checks and places in the code that
6224 would previously leak memory on the error path when such an allocation
6225 failed have been fixed.

Benjamin Petersone977ad42008-08-20 01:42:01 +00006232- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6233 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6234
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006235- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6236 version reported by these tools does not necessarily follow the python
6237 version numbering scheme, so the module is less strict when parsing it.
6238
Nick Coghlanf70385a2008-08-18 12:42:46 +00006239- Issue #2235: Added Py3k warnings for types which will become unhashable
6240 under the stricter __hash__ inheritance rules in 3.0. Several types
6241 which did not meet the rules for hash invariants and were already
6242 unhashable in 3.0 have now been explicitly flagged as unhashable in
6243 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6244 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6245

6301 the reload() built-in has been removed.
6302
Brett Cannon7e30b672008-08-04 21:52:25 +00006303- Changed code in the following modules/packages to remove warnings raised

Antoine Pitroude781a42008-08-09 12:43:23 +00006315 asking for a specific length. This problem only affected files opened
6316 using the new "io" module, not the built-in open() function.

6344
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00006345- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

6358 interaction with the tp_hash slot (added in 2.6b2) are now documented
6359
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00006360- Issue #643841: The language reference now provides more detailed
6361 coverage of the lookup process for special methods. The disclaimers
6362 regarding lack of coverage of new-style classes have also been
6363 removed, since the coverage is now fairly reasonable.

6367================================
6368
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006369*Release date: 17-Jul-2008*
6370
Raymond Hettingere3ae6552008-06-20 04:18:15 +00006371Core and Builtins
6372-----------------
6373
Georg Brandl3e483f62008-07-16 22:57:41 +00006374- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6375 its methods now allow for items objects that can be converted to
6376 an integer using operator.index().
6377
Mark Dickinson64b7e502008-07-16 09:40:03 +00006378- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6379 produced a ValueError instead of giving the correct float.
6380
Eric Smitha5fa5a22008-07-16 00:11:49 +00006381- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6382 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6383
Mark Dickinson7103aa42008-07-15 19:08:33 +00006384- Issue #3008: the float type has a new instance method 'float.hex'
6385 and a new class method 'float.fromhex' to convert floating-point
6386 numbers to and from hexadecimal strings, respectively.
6387
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006388- Issue #2235: __hash__ is once again inherited by default. To allow
6389 collections.Hashable to remain meaningful in the presence of the
6390 default hash implementation (object.__hash__), it is now possible
6391 to explicit block inheritance of hash by setting __hash__=None at
6392 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6393 level.
6394
Nick Coghlanb028f502008-07-13 14:52:36 +00006395- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6396 the parent module cannot be found while performing an absolute import.
6397 This means that an incorrectly defined __package__ attribute will
6398 now only prevent relative imports in that module rather than causing
6399 all imports from that module to fail.
6400
Nick Coghlan14ff9942008-07-08 14:21:42 +00006401- Issue #2517: Allow unicode messages in Exceptions again by correctly
6402 bypassing the instance dictionary when looking up __unicode__ on
6403 new-style classes.
6404
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00006405- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
6406 set to a custom object whose write() method happens to install
6407 another file in sys.stdout.
6408
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00006409- Issue #3088: Corrected a race condition in classes derived from
6410 threading.local: the first member set by a thread could be saved in
6411 another thread's dictionary.
6412
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006413- Issue #3004: Minor change to slice.indices(): the start and stop
6414 arguments are now treated identically, making the behaviour easier
6415 to describe and understand. For example, slice(None, -10,
6416 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6417 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6418 10, -1).
6419
Georg Brandl278fc502008-07-19 12:46:12 +00006420- Issue #3219: Calling a function with repeated keyword arguments,
6421 f(a=2, a=23), would not cause a syntax error. This was a regression
6422 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00006423
Georg Brandl278fc502008-07-19 12:46:12 +00006424- Issue #2862: Make int and float freelist management consistent with
6425 other freelists. Changes their CompactFreeList apis into
6426 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00006431- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
6432 api functions without holding the GIL, which could lead to a fatal
6433 error when they failed.
6434
Martin v. Löwisaabf4042008-08-02 07:20:25 +00006435- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

6444 ForkingPickler.register() to resolve conflict with ctypes.
6445
Vinay Sajip51e65192008-07-18 09:01:10 +00006446- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006458- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00006459
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006460- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
6461 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006462 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006463 content-length. The problem had been corrected in the 2.4 branch, but never
6464 merged into trunk.
6465

Nick Coghlanc060b0e2008-07-02 13:09:19 +00006479- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
6480 handling is now the same as that of other special attributes like __name__).
6481
Brett Cannon8bb8fa52008-07-02 01:57:08 +00006482- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Ronald Oussoren5640ce22008-06-05 12:58:24 +00006870- On MacOS X it is now possible to install the framework in 64-bit
6871 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00006872 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006873
6874 This is controlled by the configure argument ``--with-universal-archs``:
6875
6876 - ``--with-universal-archs=all``: install 4-way universal
6877
6878 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6879
6880 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6881
6882 This option should be used in combination with ``--enable-universalsdk=``.
6883
6884 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 +00006934- Issue #1631171: Re-implement the 'warnings' module in C (the
6935 original Python code has been kept as backup). This will allow for
6936 using the 'warning's machinery in such places as the parser where
6937 use of pure Python code is not possible. Both the ``showarning()``
6938 and ``formatwarning()`` gain an optional 'line' argument which is
6939 not called by default for backwards-compatibility reasons. Setting
6940 ``warnings.showwarning()`` to an implementation that lacks support
6941 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007004- Issue #2550: The approach used by client/server code for obtaining
7005 ports to listen on in network-oriented tests has been refined in an
7006 effort to facilitate running multiple instances of the entire
7007 regression test suite in parallel without issue.
7008 test_support.bind_port() has been fixed such that it will always
7009 return a unique port -- which wasn't always the case with the
7010 previous implementation, especially if socket options had been set
7011 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7012 new implementation of bind_port() will actually raise an exception
7013 if it is passed an AF_INET/SOCK_STREAM socket with either the
7014 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7015 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7016 the socket it's been passed. This currently only applies to
7017 Windows. This option prevents any other sockets from binding to the
7018 host/port we've bound to, thus removing the possibility of the
7019 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7020 when a second SOCK_STREAM socket binds and accepts to a host/port
7021 that's already been bound by another socket. The optional preferred
7022 port parameter to bind_port() has been removed. Under no
7023 circumstances should tests be hard coding ports!
7024
7025 test_support.find_unused_port() has also been introduced, which will
7026 pass a temporary socket object to bind_port() in order to obtain an
7027 unused port. The temporary socket object is then closed and
7028 deleted, and the port is returned. This method should only be used
7029 for obtaining an unused port in order to pass to an external program
7030 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7031 a parameter to a server-oriented class that doesn't give you direct
7032 access to the underlying socket used.
7033
7034 Finally, test_support.HOST has been introduced, which should be used
7035 for the host argument of any relevant socket calls (i.e. bind and
7036 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007037
7038 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007039 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007040 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7041 test_asynchat and test_socket_ssl.
7042
Georg Brandl3ee81df2008-05-17 18:14:43 +00007043 It is now possible for multiple instances of the regression test
7044 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00007098- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00007099 \Uxxxxxxxx did not accept values outside the Basic Multilingual
7100 Plane. This affected raw unicode literals and the

7102 this case, like normal unicode literals and the 'unicode-escape'
7103 codec.

7326 differ slightly in their output formats from the existing, unchanged
7327 Python 2.6 builtins. The expected usage of the future_builtins
7328 module is:
7329 from future_builtins import hex, oct
7330
Eric Smith7ef40bf2008-02-20 23:34:22 +00007331- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7332 exponents for exponents with absolute value < 100. Follows C99
7333 standard. This is a change on Windows, which would use 3 digits.
7334 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7335 so that any alterations it does to the resulting string will be
7336 available in stringlib/formatter.h (for float.__format__).
7337
Eric Smith5a3c1352008-02-19 13:21:56 +00007338- Implemented PEP 3101, Advanced String Formatting. This adds a new
7339 builtin format(); a format() method for str and unicode; a
7340 __format__() method to object, str, unicode, int, long, float, and
7341 datetime; the class string.Formatter; and the C API
7342 PyObject_Format().
7343
Georg Brandl3ee81df2008-05-17 18:14:43 +00007344- Fixed several potential crashes, all caused by specially crafted
7345 __del__ methods exploiting objects in temporarily inconsistent
7346 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00007347
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007348- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00007349 prevent a possible crash: an Abstract Base Class would try to access
7350 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00007351

Georg Brandl3ee81df2008-05-17 18:14:43 +00007355- Clear all free lists during a gc.collect() of the highest generation
7356 in order to allow pymalloc to free more arenas. Python may give back
7357 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007358
Georg Brandl3ee81df2008-05-17 18:14:43 +00007359- Issue #2045: Fix an infinite recursion triggered when printing a
7360 subclass of collections.defaultdict, if its default_factory is set
7361 to a bound method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007389- Patch #1473257: generator objects gain a gi_code attribute. This is
7390 the same object as the func_code attribute of the function that
7391 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007392
Georg Brandl3ee81df2008-05-17 18:14:43 +00007393- Issue #1920: "while 0" statements were completely removed by the
7394 compiler, even in the presence of an "else" clause, which is
7395 supposed to be run when the condition is false. Now the compiler
7396 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007397
Guido van Rossumeead05f2008-01-24 18:21:02 +00007398- A few crashers fixed: weakref_in_del.py (issue #1377858);
7399 loosing_dict_ref.py (issue #1303614, test67.py);
7400 borrowed_ref_[34].py (not in tracker).

7405
Georg Brandl3ee81df2008-05-17 18:14:43 +00007406- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007407 several extension methods and modules do not work without unicode
7408 support.
7409
Georg Brandl26543b12008-01-21 18:36:51 +00007410- Issue #1882: when compiling code from a string, encoding cookies in the

7414
Georg Brandl6caad7d2008-01-26 14:19:22 +00007415- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007416 added.
7417
Christian Heimesc94e2b52008-01-14 04:13:37 +00007418- sys.float_info / PyFloat_GetInfo: The floating point information
7419 object was converted from a dict to a specialized structseq object.
7420
Georg Brandl3ee81df2008-05-17 18:14:43 +00007421- Patch #1816: Added sys.flags structseq. It exposes the status of
7422 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007423
Georg Brandl3ee81df2008-05-17 18:14:43 +00007424- Objects/structseq.c: Implemented new structseq representation. The
7425 patch makes structseqs (e.g. the return value of os.stat) more
7426 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007427
Georg Brandl3ee81df2008-05-17 18:14:43 +00007428- Patch #1700288: added a type attribute cache that caches method
7429 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00007430
Neal Norwitz3fc15b82008-01-10 05:42:58 +00007431- Bug #1776: __import__() no longer accepts filenames on any platform.

7437 envvar and sys.dont_write_bytecode attribute. All these can be set
7438 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007439
Georg Brandl3ee81df2008-05-17 18:14:43 +00007440- Improve some exception messages when Windows fails to load an
7441 extension module. Now we get for example '%1 is not a valid Win32
7442 application' instead of 'error code 193'.

7499
Georg Brandl21e99f42010-03-07 15:23:59 +00007500- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007501 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7502 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007503
Georg Brandl3ee81df2008-05-17 18:14:43 +00007504- Issue #1686386: Tuple's tp_repr did not take into account the
7505 possibility of having a self-referential tuple, which is possible
7506 from C code. Nor did object's tp_str consider that a type's tp_str
7507 could do something that could lead to an inifinite recursion.
7508 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7509 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007510
Georg Brandl3ee81df2008-05-17 18:14:43 +00007511- Issue #1164: It was possible to trigger deadlock when using the
7512 'print' statement to write to a file since the GIL was not released
7513 as needed. Now PyObject_Print() does the right thing along with
7514 various tp_print implementations of the built-in types and those in
7515 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007516

Georg Brandl3ee81df2008-05-17 18:14:43 +00007525 PyObject_Call() never calling back out to Python code to trigger
7526 recursion depth updates/checks. Required the creation of a static
7527 RuntimeError instance in case normalizing an exception put the
7528 recursion check value past its limit. Fixes crashers

Raymond Hettinger4db5fe92007-04-12 04:10:00 +00007568- Request #1193128: str.translate() now allows a None argument for
7569 translations that only remove characters without re-mapping the
7570 remaining characters.
7571
Georg Brandl5cb76c12007-03-21 09:00:39 +00007572- Patch #1682205: a TypeError while unpacking an iterable is no longer
7573 masked by a generic one with the message "unpack non-sequence".

7576
Guido van Rossum143b5642007-03-23 04:58:42 +00007577- Bug #1683368: The object.__init__() and object.__new__() methods are
7578 now stricter in rejecting excess arguments. The only time when
7579 either allows excess arguments is when it is not overridden and the
7580 other one is. For backwards compatibility, when both are
7581 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007582 warning later). Also, type.__init__() insists on the same signature
7583 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00007585- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7586 object to complex using its __complex__() method before falling back
7587 to the __float__() method. Therefore, the functions in the cmath
7588 module now can operate on objects that define a __complex__()
7589 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00007607- Bug #1678647: write a newline after printing an exception in any
7608 case, even when converting the value to a string failed.
7609
Georg Brandl871f1bc2007-03-12 13:17:36 +00007610- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007611 its argument, if it exists. If not, it will work like before. This
7612 allows customizing the output of dir() in the presence of a
7613 __getattr__().

7623 raising a ValueError.

Georg Brandlaa2321b2007-03-07 00:40:28 +00007625- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007626 makes the filenames the warning module prints much more sensible
7627 when a PYTHONSTARTUP file is used.

7641 sq_ass_slice instead of the sq_slice slot.
7642
Georg Brandl3ee81df2008-05-17 18:14:43 +00007643- When printing an unraisable error, don't print exceptions. before

Georg Brandl2c1375c2006-10-12 11:27:59 +00007695- Bug #1545497: when given an explicit base, int() did ignore NULs
7696 embedded in the string to convert.
7697
Georg Brandl846f73a2006-10-08 07:11:54 +00007698- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00007746 generator expressions (x for x, in ... ) works again. Fixing this
7747 problem required changing the .pyc magic number. This means that
7748 .pyc files generated before 2.5c2 will be regenerated.

Guido van Rossum8bc09652008-02-21 18:18:37 +00007787- Removed uses of dict.has_key() from distutils, and uses of

8270 TestCase and TestSuite subclasses (not instances) are no longer

Georg Brandl3ee81df2008-05-17 18:14:43 +00008551- The implementation of UnicodeError objects has been simplified
8552 (start and end attributes are now stored directly as Py_ssize_t
8553 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00008554
Georg Brandl3ee81df2008-05-17 18:14:43 +00008555- Issue #829951: In the smtplib module, SMTP.starttls() now complies
8556 with RFC 3207 and forgets any knowledge obtained from the server not
8557 obtained from the TLS negotiation itself. Patch contributed by Bill
8558 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00008559
Georg Brandl3ee81df2008-05-17 18:14:43 +00008560- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00008561 that the SMTP.starttls() caller no longer needs to call ehlo()
8562 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00008563 does not claim to support starttls. Adds the
8564 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
8565 Fenner.

8645 complex, tuple, list, dict, set, and frozenset. Formerly, it would
8646 silently miscode subclasses of those types. Now, it raises a
8647 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00008648

Georg Brandl3ee81df2008-05-17 18:14:43 +00008663 time so that opening a database previously created with the DB_DUP
8664 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8665 opens. Specifically: dictionary assignment to a DB object will
8666 replace all values for a given key when the database allows
8667 duplicate values. DB users should use DB.put(k, v) when they want
8668 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00008669

8675 characters with ASCII value less than 32. Also, it correctly quotes
8676 dots only if they occur on a single line, as opposed to the previous
8677 behavior of quoting dots if they are the second character of any
8678 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00008679

Georg Brandl3ee81df2008-05-17 18:14:43 +00009084- Removed the macfs module. It had been deprecated since Python 2.5.
9085 This lead to the deprecation of macostools.touched() as it relied
9086 solely on macfs and was a no-op under OS X.
