Ned Deily18fae3f2013-01-31 01:24:55 -0800862- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
863 In particular, fix extension module build failures when trying to use
864 32-bit-only installer Pythons on systems with Xcode 4 (currently
865 OS X 10.8, 10.7, and optionally 10.6).
866 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
867 * Since Xcode 4 removes ppc support, extension module builds now
868 check for ppc compiler support and by default remove ppc and
869 ppc64 archs when they are not available.
870 * Extension module builds now revert to using system installed
871 headers and libs (/usr and /System/Library) if the SDK used
872 to build the interpreter is not installed or has moved.
873 * Try to avoid building extension modules with deprecated
874 and problematic Apple llvm-gcc compiler. If original compiler
875 is not available, use clang instead by default.

Florent Xiclunac2279652012-02-12 14:49:03 +01001234- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01001235 has left two versions of customize_compiler, the original in
1236 distutils.sysconfig and another copy in distutils.ccompiler, with some

1239 is the case in 3.x.

Ned Deily0d0ea482012-02-10 12:59:06 +01001241- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1242 Distutils-based packages with C extension modules may fail because
1243 Apple has removed gcc-4.2, the version used to build python.org
1244 64-bit/32-bit Pythons. If the user does not explicitly override
1245 the default C compiler by setting the CC environment variable,
1246 Distutils will now attempt to compile extension modules with clang
1247 if gcc-4.2 is required but not found. Also as a convenience, if
1248 the user does explicitly set CC, substitute its value as the default
1249 compiler in the Distutils LDSHARED configuration variable for OS X.
1250 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1251 SDK, neither of which are available in Xcode 4. This change does not
1252 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001525- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1526 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1527 interpreter process. This could cause failures in non-Distutils subprocesses
1528 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02001529 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07001530 deployment target only in the environment of each build subprocess. It is
1531 still possible to globally override the default by setting
1532 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1533 greater or equal to the default value, the value with which the interpreter
1534 was built.

1563 updating the check interval, so if the user decreases the check interval,
1564 the ticker doesn't have to wind down to zero from the old starting point
1565 before the new interval takes effect. And if the user increases the
1566 interval, it makes sure the new limit takes effect right away rather have an
1567 early task switch before recognizing the new interval.

Raymond Hettinger20397532010-09-12 02:11:45 +00002518- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
2519 This prevents user-created self-referencing ordered dictionaries from
2520 becoming permanently uncollectable GC garbage. The downside is that
2521 removing __del__ means that the internal doubly-linked list has to wait for
2522 GC collection rather than freeing memory immediately when the refcnt drops
2523 to zero.

2531 to fetch the original errno, or to filter timeout errors. Now the
2532 original error is re-raised.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00002982- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
2983 start byte and the continuation byte(s) are now considered invalid, instead
2984 of the number of bytes specified by the start byte.
2985 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
2986 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
2987 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00002996- Issue #8748: Fix two issues with comparisons between complex and integer
2997 objects. (1) The comparison could incorrectly return True in some cases
2998 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
2999 (2) The comparison raised an OverflowError for large integers, leading
3000 to unpredictable exceptions when combining integers and complex objects
3001 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +00003003- Issue #5211: Implicit coercion for the complex type is now completely

Georg Brandlba83f822010-03-14 09:50:54 +00003881 file position when calling `truncate()`. It would previously change the file
3882 position to the given argument, which goes against the tradition of

3886 class used to represent files stored inside an archive. The new
3887 implementation is significantly faster and can be wrapped in a
3888 ``io.BufferedReader`` object for more speedups. It also solves an issue
3889 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00003980- The ``__complex__()`` method is now looked up on the class of instances to
3981 make it consistent with other special methods.

3985
Mark Dickinson1b34d252010-01-01 17:27:30 +00003986- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00003987 DeprecationWarning when passed a float argument where an integer was expected.
3988 These functions and methods now raise TypeError instead. The majority of the
3989 effects of this change are in the extension modules, but some core functions
3990 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3991 and many unicode/str methods.

4006 least on IEEE 754 platforms), and in particular does not depend on the
4007 internal representation of a long.

4015
Georg Brandlba83f822010-03-14 09:50:54 +00004016 These executables now work properly with the arch(1) command: ``arch -ppc

Georg Brandlba83f822010-03-14 09:50:54 +00004103- Issue #5080: The argument parsing functions ``PyArg_ParseTuple()``,
4104 ``PyArg_ParseTupleAndKeywords()``, ``PyArg_VaParse()``,
4105 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept
4106 float arguments for integer format codes (other than 'L'): previously an
4107 attempt to pass a float resulted in a DeprecationWarning; now it gives a
4108 TypeError. For the 'L' format code (which previously had no warning) there is
4109 now a DeprecationWarning.

4157 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
4158 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00004159
Georg Brandlba83f822010-03-14 09:50:54 +00004160- Remove switch from "%f" formatting to "%g" formatting for floats larger than
4161 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00004162
Georg Brandlba83f822010-03-14 09:50:54 +00004163- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
4164 1e-100 used to raise OverflowError, but now gives the requested 120
4165 significant digits instead.

Georg Brandlba83f822010-03-14 09:50:54 +00004174- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4175 decimal string that's guaranteed to round back to x under correct rounding
4176 (with round-half-to-even rounding mode). Previously it gave a string based on
4177 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4178 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4179 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004180
Georg Brandlba83f822010-03-14 09:50:54 +00004181- Issue #7117: On almost all platforms: float-to-string and string-to-float
4182 conversions within Python are now correctly rounded. Places these conversions
4183 occur include: str for floats and complex numbers; the float and complex
4184 constructors; old-style and new-style numeric formatting; serialization and
4185 deserialization of floats and complex numbers using marshal, pickle and json;
4186 parsing of float and imaginary literals in Python code; Decimal-to-float
4187 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004188
Georg Brandlba83f822010-03-14 09:50:54 +00004189 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4190 providing correctly-rounded strtod and dtoa C functions. This code is
4191 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4192 the C compiler. There may be a small number of platforms on which correct
4193 operation of this code cannot be guaranteed, so the code is not used: notably,
4194 this applies to platforms where the C double format is not IEEE 754 binary64,
4195 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4196 and Python's configure script is unable to determine how to change the FPU
4197 precision. On these platforms conversions use the platform strtod and dtoa,
4198 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004199
Georg Brandlba83f822010-03-14 09:50:54 +00004200- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4201 uses the correctly-rounded string <-> float conversions described above (when
4202 available), and so produces correctly rounded results that will display nicely
4203 under the float repr. There are two related small changes: (1) round now
4204 accepts any class with an ``__index__()`` method for its second argument (but
4205 no longer accepts floats for the second argument), and (2) an excessively
4206 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4207 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00004349
Georg Brandlba83f822010-03-14 09:50:54 +00004350 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
4351 (2) parsing of strings representing infinities and nans was locale aware; and
4352 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00004354- Issue #5920: For ``float.__format__()``, change the behavior with the empty
4355 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
4356 but with at least one decimal point and with a default precision
4357 of 12. Previously, the behavior the same but with a default precision of 6.
4358 This more closely matches ``str()``, and reduces surprises when adding
4359 alignment flags to the empty presentation type. This also affects the new
4360 complex.__format__ in the same way.
4361
4362- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

4434 internal representation of integers, for performance reasons. Base 2**30 is
4435 enabled by default on 64-bit machines. Add --enable-big-digits option to

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00005988- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
5989
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005990- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5991 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5992 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5993 ``printf`` function, whereas PyString_FromFormat has an independent
5994 implementation and uses "%zd" on all platforms for size_t values.
5995 This makes a difference on win64, where ``printf`` needs "%Id" to display
5996 64bit values.
5997
Benjamin Peterson97179b02008-09-09 20:55:01 +00005998- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00006001- Issue #3777: long() applied to a float object now always return a long
6002 object; previously an int would be returned for small values. the __long__
6003 method is allowed to return either an int or a long, but the behaviour of
6004 float objects should not change to respect backward compatibility.
6005
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00006006- Issue #3751: str.rpartition would perform a left-partition when called with
6007 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +00006012 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006013 was correctly parsed but parsing of subsequent arguments failed.
6014
Vinay Sajip35e3b032008-09-01 14:33:59 +00006015- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006016 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6017 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6018 when given a tuple of classes as second argument, were looking up
6019 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6020 type object.
6021
Neal Norwitz18aa3882008-08-24 05:04:52 +00006022- Fix crashes on memory allocation failure found with failmalloc.

Brett Cannon1eaf0742008-09-02 01:25:16 +00006091 warnings.catch_warnings() along with some API cleanup. Expanding the tests
6092 for catch_warnings() also led to an improvement in the raising of a

6165-----------------
6166
Guido van Rossumf8402962008-08-20 15:01:50 +00006167- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6168 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6169 extensions do not automatically benefit from the class attribute
6170 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6171 to their tp_flags field if they care. This is a backwards
6172 compatibility feature; in 3.0, all types will use the cache by
6173 default.
6174
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006175- Keyword arguments can now follow starred arguments. (``f(a, *args,
6176 keyword=23)`` is now valid syntax.)
6177
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006178- ctypes function pointers that are COM methods have a boolean True
6179 value again.
6180
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006181- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6182 by denying s# to parse objects that have a releasebuffer procedure,
6183 and introducing s*.
6184
Georg Brandl1e13ea92008-08-11 09:07:59 +00006185- Issue #3537: Fix an assertion failure when an empty but presized dict
6186 object was stored in the freelist.
6187
Mark Dickinsonb6467572008-08-04 21:30:09 +00006188- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6189 ValueError consistently across platforms.
6190
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006191- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6192 (64bit Unix, for example), unichr() would truncate its argument and return
6193 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6194
Neal Norwitze7d8be82008-07-31 17:17:14 +00006195- Apply security patches from Apple.
6196
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006197- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6198 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6199
Antoine Pitrou92f82162008-07-25 22:22:08 +00006200- Issue #1819: function calls with several named parameters are now on
6201 average 35% faster (as measured by pybench).
6202
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006203- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6204 the python debugger steps into a class statement: the free variables (local
6205 variables defined in an outer scope) would be deleted from the outer scope.
6206
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006207- Issue #2620: Overflow checking when allocating or reallocating memory
6208 was not always being done properly in some python types and extension
6209 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6210 all been updated to perform better checks and places in the code that
6211 would previously leak memory on the error path when such an allocation
6212 failed have been fixed.

Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00006217- Issue #3612: Added some missing basic types in ctypes.wintypes.
6218
Benjamin Petersone977ad42008-08-20 01:42:01 +00006219- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6220 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6221
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006222- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6223 version reported by these tools does not necessarily follow the python
6224 version numbering scheme, so the module is less strict when parsing it.
6225
Nick Coghlanf70385a2008-08-18 12:42:46 +00006226- Issue #2235: Added Py3k warnings for types which will become unhashable
6227 under the stricter __hash__ inheritance rules in 3.0. Several types

Antoine Pitroude781a42008-08-09 12:43:23 +00006302 asking for a specific length. This problem only affected files opened

6345 interaction with the tp_hash slot (added in 2.6b2) are now documented
6346
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00006347- Issue #643841: The language reference now provides more detailed

6354================================
6355
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006356*Release date: 17-Jul-2008*
6357
Raymond Hettingere3ae6552008-06-20 04:18:15 +00006358Core and Builtins
6359-----------------
6360
Georg Brandl3e483f62008-07-16 22:57:41 +00006361- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6362 its methods now allow for items objects that can be converted to
6363 an integer using operator.index().
6364
Mark Dickinson64b7e502008-07-16 09:40:03 +00006365- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6366 produced a ValueError instead of giving the correct float.
6367
Eric Smitha5fa5a22008-07-16 00:11:49 +00006368- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6369 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6370
Mark Dickinson7103aa42008-07-15 19:08:33 +00006371- Issue #3008: the float type has a new instance method 'float.hex'
6372 and a new class method 'float.fromhex' to convert floating-point
6373 numbers to and from hexadecimal strings, respectively.
6374
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006375- Issue #2235: __hash__ is once again inherited by default. To allow
6376 collections.Hashable to remain meaningful in the presence of the
6377 default hash implementation (object.__hash__), it is now possible
6378 to explicit block inheritance of hash by setting __hash__=None at
6379 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6380 level.
6381
Nick Coghlanb028f502008-07-13 14:52:36 +00006382- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6383 the parent module cannot be found while performing an absolute import.
6384 This means that an incorrectly defined __package__ attribute will
6385 now only prevent relative imports in that module rather than causing
6386 all imports from that module to fail.
6387
Nick Coghlan14ff9942008-07-08 14:21:42 +00006388- Issue #2517: Allow unicode messages in Exceptions again by correctly
6389 bypassing the instance dictionary when looking up __unicode__ on
6390 new-style classes.
6391
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00006392- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
6393 set to a custom object whose write() method happens to install
6394 another file in sys.stdout.
6395
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00006396- Issue #3088: Corrected a race condition in classes derived from
6397 threading.local: the first member set by a thread could be saved in
6398 another thread's dictionary.
6399
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006400- Issue #3004: Minor change to slice.indices(): the start and stop
6401 arguments are now treated identically, making the behaviour easier
6402 to describe and understand. For example, slice(None, -10,
6403 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6404 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6405 10, -1).
6406
Georg Brandl278fc502008-07-19 12:46:12 +00006407- Issue #3219: Calling a function with repeated keyword arguments,
6408 f(a=2, a=23), would not cause a syntax error. This was a regression
6409 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00006410
Georg Brandl278fc502008-07-19 12:46:12 +00006411- Issue #2862: Make int and float freelist management consistent with
6412 other freelists. Changes their CompactFreeList apis into
6413 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00006418- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
6419 api functions without holding the GIL, which could lead to a fatal
6420 error when they failed.
6421
Martin v. Löwisaabf4042008-08-02 07:20:25 +00006422- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

6431 ForkingPickler.register() to resolve conflict with ctypes.
6432
Vinay Sajip51e65192008-07-18 09:01:10 +00006433- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Raymond Hettinger3cd1e422008-07-10 14:03:19 +00006446
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006447- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
6448 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006449 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006450 content-length. The problem had been corrected in the 2.4 branch, but never
6451 merged into trunk.

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006464 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00006465
Nick Coghlanc060b0e2008-07-02 13:09:19 +00006466- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
6467 handling is now the same as that of other special attributes like __name__).
6468
Brett Cannon8bb8fa52008-07-02 01:57:08 +00006469- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

6858 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00006859 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006860
6861 This is controlled by the configure argument ``--with-universal-archs``:
6862
6863 - ``--with-universal-archs=all``: install 4-way universal
6864
6865 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6866
6867 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6868
6869 This option should be used in combination with ``--enable-universalsdk=``.
6870
6871 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 +00006921- Issue #1631171: Re-implement the 'warnings' module in C (the
6922 original Python code has been kept as backup). This will allow for
6923 using the 'warning's machinery in such places as the parser where
6924 use of pure Python code is not possible. Both the ``showarning()``
6925 and ``formatwarning()`` gain an optional 'line' argument which is
6926 not called by default for backwards-compatibility reasons. Setting
6927 ``warnings.showwarning()`` to an implementation that lacks support
6928 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006991- Issue #2550: The approach used by client/server code for obtaining
6992 ports to listen on in network-oriented tests has been refined in an
6993 effort to facilitate running multiple instances of the entire
6994 regression test suite in parallel without issue.
6995 test_support.bind_port() has been fixed such that it will always
6996 return a unique port -- which wasn't always the case with the
6997 previous implementation, especially if socket options had been set
6998 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6999 new implementation of bind_port() will actually raise an exception
7000 if it is passed an AF_INET/SOCK_STREAM socket with either the
7001 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7002 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7003 the socket it's been passed. This currently only applies to
7004 Windows. This option prevents any other sockets from binding to the
7005 host/port we've bound to, thus removing the possibility of the
7006 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7007 when a second SOCK_STREAM socket binds and accepts to a host/port
7008 that's already been bound by another socket. The optional preferred
7009 port parameter to bind_port() has been removed. Under no
7010 circumstances should tests be hard coding ports!
7011
7012 test_support.find_unused_port() has also been introduced, which will
7013 pass a temporary socket object to bind_port() in order to obtain an
7014 unused port. The temporary socket object is then closed and
7015 deleted, and the port is returned. This method should only be used
7016 for obtaining an unused port in order to pass to an external program
7017 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7018 a parameter to a server-oriented class that doesn't give you direct
7019 access to the underlying socket used.
7020
7021 Finally, test_support.HOST has been introduced, which should be used
7022 for the host argument of any relevant socket calls (i.e. bind and
7023 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007024
7025 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007026 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007027 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7028 test_asynchat and test_socket_ssl.
7029
Georg Brandl3ee81df2008-05-17 18:14:43 +00007030 It is now possible for multiple instances of the regression test
7031 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00007085- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00007086 \Uxxxxxxxx did not accept values outside the Basic Multilingual
7087 Plane. This affected raw unicode literals and the
7088 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
7089 this case, like normal unicode literals and the 'unicode-escape'
7090 codec.

Eric Smitha73fbe72008-02-23 03:09:44 +00007310- Added the future_builtins module, which contains hex() and oct().
7311 These are the PEP 3127 version of these functions, designed to be
7312 compatible with the hex() and oct() builtins from Python 3.0. They
7313 differ slightly in their output formats from the existing, unchanged
7314 Python 2.6 builtins. The expected usage of the future_builtins
7315 module is:

7317
Eric Smith7ef40bf2008-02-20 23:34:22 +00007318- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7319 exponents for exponents with absolute value < 100. Follows C99
7320 standard. This is a change on Windows, which would use 3 digits.
7321 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7322 so that any alterations it does to the resulting string will be
7323 available in stringlib/formatter.h (for float.__format__).
7324
Eric Smith5a3c1352008-02-19 13:21:56 +00007325- Implemented PEP 3101, Advanced String Formatting. This adds a new
7326 builtin format(); a format() method for str and unicode; a
7327 __format__() method to object, str, unicode, int, long, float, and
7328 datetime; the class string.Formatter; and the C API
7329 PyObject_Format().
7330
Georg Brandl3ee81df2008-05-17 18:14:43 +00007331- Fixed several potential crashes, all caused by specially crafted
7332 __del__ methods exploiting objects in temporarily inconsistent
7333 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00007334
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007335- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00007336 prevent a possible crash: an Abstract Base Class would try to access
7337 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00007338

Georg Brandl3ee81df2008-05-17 18:14:43 +00007342- Clear all free lists during a gc.collect() of the highest generation
7343 in order to allow pymalloc to free more arenas. Python may give back
7344 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007345
Georg Brandl3ee81df2008-05-17 18:14:43 +00007346- Issue #2045: Fix an infinite recursion triggered when printing a
7347 subclass of collections.defaultdict, if its default_factory is set
7348 to a bound method.

Christian Heimesf75dbef2008-02-08 00:11:31 +00007350- Fixed a minor memory leak in dictobject.c. The content of the free
7351 list was not freed on interpreter shutdown.
7352
Georg Brandl21e99f42010-03-07 15:23:59 +00007353- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00007354 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00007355

Georg Brandl3ee81df2008-05-17 18:14:43 +00007376- Patch #1473257: generator objects gain a gi_code attribute. This is
7377 the same object as the func_code attribute of the function that
7378 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007379
Georg Brandl3ee81df2008-05-17 18:14:43 +00007380- Issue #1920: "while 0" statements were completely removed by the
7381 compiler, even in the presence of an "else" clause, which is
7382 supposed to be run when the condition is false. Now the compiler
7383 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007384
Guido van Rossumeead05f2008-01-24 18:21:02 +00007385- A few crashers fixed: weakref_in_del.py (issue #1377858);
7386 loosing_dict_ref.py (issue #1303614, test67.py);
7387 borrowed_ref_[34].py (not in tracker).
7388
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00007389- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00007390 suppressed while an extension is loaded by calling SetErrorMode in
7391 dynload_win.c. The error is still reported properly.
7392
Georg Brandl3ee81df2008-05-17 18:14:43 +00007393- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007394 several extension methods and modules do not work without unicode
7395 support.
7396
Georg Brandl26543b12008-01-21 18:36:51 +00007397- Issue #1882: when compiling code from a string, encoding cookies in the

7401
Georg Brandl6caad7d2008-01-26 14:19:22 +00007402- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007403 added.
7404
Christian Heimesc94e2b52008-01-14 04:13:37 +00007405- sys.float_info / PyFloat_GetInfo: The floating point information
7406 object was converted from a dict to a specialized structseq object.
7407
Georg Brandl3ee81df2008-05-17 18:14:43 +00007408- Patch #1816: Added sys.flags structseq. It exposes the status of
7409 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007410
Georg Brandl3ee81df2008-05-17 18:14:43 +00007411- Objects/structseq.c: Implemented new structseq representation. The
7412 patch makes structseqs (e.g. the return value of os.stat) more
7413 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007414
Georg Brandl3ee81df2008-05-17 18:14:43 +00007415- Patch #1700288: added a type attribute cache that caches method
7416 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00007417
Neal Norwitz3fc15b82008-01-10 05:42:58 +00007418- Bug #1776: __import__() no longer accepts filenames on any platform.

7424 envvar and sys.dont_write_bytecode attribute. All these can be set
7425 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007426
Georg Brandl3ee81df2008-05-17 18:14:43 +00007427- Improve some exception messages when Windows fails to load an
7428 extension module. Now we get for example '%1 is not a valid Win32
7429 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00007436- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00007437 and INF. float("nan"), float("inf") and float("-inf") now work on
7438 every platform with IEEE 754 semantics.

7486
Georg Brandl21e99f42010-03-07 15:23:59 +00007487- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007488 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7489 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007490
Georg Brandl3ee81df2008-05-17 18:14:43 +00007491- Issue #1686386: Tuple's tp_repr did not take into account the
7492 possibility of having a self-referential tuple, which is possible
7493 from C code. Nor did object's tp_str consider that a type's tp_str
7494 could do something that could lead to an inifinite recursion.
7495 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7496 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007497
Georg Brandl3ee81df2008-05-17 18:14:43 +00007498- Issue #1164: It was possible to trigger deadlock when using the
7499 'print' statement to write to a file since the GIL was not released
7500 as needed. Now PyObject_Print() does the right thing along with
7501 various tp_print implementations of the built-in types and those in
7502 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007503
Georg Brandl3ee81df2008-05-17 18:14:43 +00007504- Issue #1147: Exceptions were directly allowing string exceptions in

Georg Brandl3ee81df2008-05-17 18:14:43 +00007512 PyObject_Call() never calling back out to Python code to trigger
7513 recursion depth updates/checks. Required the creation of a static
7514 RuntimeError instance in case normalizing an exception put the
7515 recursion check value past its limit. Fixes crashers

Georg Brandl5cb76c12007-03-21 09:00:39 +00007559- Patch #1682205: a TypeError while unpacking an iterable is no longer
7560 masked by a generic one with the message "unpack non-sequence".

Guido van Rossum143b5642007-03-23 04:58:42 +00007564- Bug #1683368: The object.__init__() and object.__new__() methods are
7565 now stricter in rejecting excess arguments. The only time when
7566 either allows excess arguments is when it is not overridden and the
7567 other one is. For backwards compatibility, when both are
7568 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007569 warning later). Also, type.__init__() insists on the same signature
7570 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00007572- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7573 object to complex using its __complex__() method before falling back
7574 to the __float__() method. Therefore, the functions in the cmath
7575 module now can operate on objects that define a __complex__()
7576 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00007594- Bug #1678647: write a newline after printing an exception in any
7595 case, even when converting the value to a string failed.
7596
Georg Brandl871f1bc2007-03-12 13:17:36 +00007597- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007598 its argument, if it exists. If not, it will work like before. This
7599 allows customizing the output of dir() in the presence of a
7600 __getattr__().

7610 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00007611
Georg Brandlaa2321b2007-03-07 00:40:28 +00007612- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007613 makes the filenames the warning module prints much more sensible
7614 when a PYTHONSTARTUP file is used.

7628 sq_ass_slice instead of the sq_slice slot.
7629
Georg Brandl3ee81df2008-05-17 18:14:43 +00007630- When printing an unraisable error, don't print exceptions. before
7631 the name. This duplicates the behavior whening normally printing

7641 created a weakref on itself during a __del__ call for new-style
7642 classes (classic classes still have the bug).

Georg Brandl2c1375c2006-10-12 11:27:59 +00007682- Bug #1545497: when given an explicit base, int() did ignore NULs
7683 embedded in the string to convert.
7684
Georg Brandl846f73a2006-10-08 07:11:54 +00007685- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl4e933132006-09-06 20:05:58 +00007715- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007733 generator expressions (x for x, in ... ) works again. Fixing this
7734 problem required changing the .pyc magic number. This means that
7735 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008538- The implementation of UnicodeError objects has been simplified
8539 (start and end attributes are now stored directly as Py_ssize_t
8540 members).

Georg Brandl3ee81df2008-05-17 18:14:43 +00008542- Issue #829951: In the smtplib module, SMTP.starttls() now complies
8543 with RFC 3207 and forgets any knowledge obtained from the server not
8544 obtained from the TLS negotiation itself. Patch contributed by Bill
8545 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00008546
Georg Brandl3ee81df2008-05-17 18:14:43 +00008547- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00008548 that the SMTP.starttls() caller no longer needs to call ehlo()
8549 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00008550 does not claim to support starttls. Adds the
8551 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
8552 Fenner.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008594- Patch #976880: ``mmap`` objects now have an ``rfind`` method that
Andrew M. Kuchling5c60bfc2008-01-19 18:18:41 +00008595 works as expected. ``mmap.find`` also takes an optional ``end``
8596 parameter.

8621 contents before adding elements from the iterable. This fix brings
8622 the behavior into line with that for list.__init__().
Raymond Hettingeradf9ffd2007-12-13 00:08:37 +00008623
Georg Brandl3ee81df2008-05-17 18:14:43 +00008624- Added wide char functions to msvcrt module: getwch, getwche, putwch

8630
Georg Brandl3ee81df2008-05-17 18:14:43 +00008631- Marshal.dumps() now expects exact type matches for int, long, float,
8632 complex, tuple, list, dict, set, and frozenset. Formerly, it would
8633 silently miscode subclasses of those types. Now, it raises a
8634 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00008635

Georg Brandl3ee81df2008-05-17 18:14:43 +00008650 time so that opening a database previously created with the DB_DUP
8651 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8652 opens. Specifically: dictionary assignment to a DB object will
8653 replace all values for a given key when the database allows
8654 duplicate values. DB users should use DB.put(k, v) when they want
8655 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00008656

8662 characters with ASCII value less than 32. Also, it correctly quotes
8663 dots only if they occur on a single line, as opposed to the previous
8664 behavior of quoting dots if they are the second character of any
8665 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00008666

Georg Brandl3ee81df2008-05-17 18:14:43 +00009071- Removed the macfs module. It had been deprecated since Python 2.5.
9072 This lead to the deprecation of macostools.touched() as it relied
9073 solely on macfs and was a no-op under OS X.
