867 32-bit-only installer Pythons on systems with Xcode 4 (currently
868 OS X 10.8, 10.7, and optionally 10.6).
869 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
870 * Since Xcode 4 removes ppc support, extension module builds now
871 check for ppc compiler support and by default remove ppc and
872 ppc64 archs when they are not available.
873 * Extension module builds now revert to using system installed
874 headers and libs (/usr and /System/Library) if the SDK used
875 to build the interpreter is not installed or has moved.
876 * Try to avoid building extension modules with deprecated
877 and problematic Apple llvm-gcc compiler. If original compiler
878 is not available, use clang instead by default.

Florent Xiclunac2279652012-02-12 14:49:03 +01001237- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01001238 has left two versions of customize_compiler, the original in
1239 distutils.sysconfig and another copy in distutils.ccompiler, with some
1240 parts of distutils calling one and others using the other.

1242 is the case in 3.x.
1243
Ned Deily0d0ea482012-02-10 12:59:06 +01001244- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1245 Distutils-based packages with C extension modules may fail because
1246 Apple has removed gcc-4.2, the version used to build python.org
1247 64-bit/32-bit Pythons. If the user does not explicitly override
1248 the default C compiler by setting the CC environment variable,
1249 Distutils will now attempt to compile extension modules with clang
1250 if gcc-4.2 is required but not found. Also as a convenience, if
1251 the user does explicitly set CC, substitute its value as the default
1252 compiler in the Distutils LDSHARED configuration variable for OS X.
1253 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1254 SDK, neither of which are available in Xcode 4. This change does not
1255 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001528- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1529 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1530 interpreter process. This could cause failures in non-Distutils subprocesses
1531 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02001532 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07001533 deployment target only in the environment of each build subprocess. It is
1534 still possible to globally override the default by setting
1535 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1536 greater or equal to the default value, the value with which the interpreter
1537 was built.

1566 updating the check interval, so if the user decreases the check interval,
1567 the ticker doesn't have to wind down to zero from the old starting point
1568 before the new interval takes effect. And if the user increases the
1569 interval, it makes sure the new limit takes effect right away rather have an
1570 early task switch before recognizing the new interval.

2520
Raymond Hettinger20397532010-09-12 02:11:45 +00002521- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
2522 This prevents user-created self-referencing ordered dictionaries from
2523 becoming permanently uncollectable GC garbage. The downside is that
2524 removing __del__ means that the internal doubly-linked list has to wait for
2525 GC collection rather than freeing memory immediately when the refcnt drops
2526 to zero.

2534 to fetch the original errno, or to filter timeout errors. Now the
2535 original error is re-raised.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00002985- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
2986 start byte and the continuation byte(s) are now considered invalid, instead
2987 of the number of bytes specified by the start byte.
2988 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
2989 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
2990 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00002999- Issue #8748: Fix two issues with comparisons between complex and integer
3000 objects. (1) The comparison could incorrectly return True in some cases
3001 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
3002 (2) The comparison raised an OverflowError for large integers, leading
3003 to unpredictable exceptions when combining integers and complex objects
3004 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +00003006- Issue #5211: Implicit coercion for the complex type is now completely

Georg Brandlba83f822010-03-14 09:50:54 +00003884 file position when calling `truncate()`. It would previously change the file
3885 position to the given argument, which goes against the tradition of

3889 class used to represent files stored inside an archive. The new
3890 implementation is significantly faster and can be wrapped in a

3892 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

3988
Mark Dickinson1b34d252010-01-01 17:27:30 +00003989- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00003990 DeprecationWarning when passed a float argument where an integer was expected.
3991 These functions and methods now raise TypeError instead. The majority of the
3992 effects of this change are in the extension modules, but some core functions
3993 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3994 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +00004106- Issue #5080: The argument parsing functions ``PyArg_ParseTuple()``,
4107 ``PyArg_ParseTupleAndKeywords()``, ``PyArg_VaParse()``,
4108 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept
4109 float arguments for integer format codes (other than 'L'): previously an
4110 attempt to pass a float resulted in a DeprecationWarning; now it gives a
4111 TypeError. For the 'L' format code (which previously had no warning) there is
4112 now a DeprecationWarning.

4161 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00004162
Georg Brandlba83f822010-03-14 09:50:54 +00004163- Remove switch from "%f" formatting to "%g" formatting for floats larger than
4164 1e50 in absolute value.

Georg Brandlba83f822010-03-14 09:50:54 +00004166- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
4167 1e-100 used to raise OverflowError, but now gives the requested 120
4168 significant digits instead.

Georg Brandlba83f822010-03-14 09:50:54 +00004177- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4178 decimal string that's guaranteed to round back to x under correct rounding
4179 (with round-half-to-even rounding mode). Previously it gave a string based on
4180 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4181 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4182 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004183
Georg Brandlba83f822010-03-14 09:50:54 +00004184- Issue #7117: On almost all platforms: float-to-string and string-to-float
4185 conversions within Python are now correctly rounded. Places these conversions
4186 occur include: str for floats and complex numbers; the float and complex
4187 constructors; old-style and new-style numeric formatting; serialization and
4188 deserialization of floats and complex numbers using marshal, pickle and json;
4189 parsing of float and imaginary literals in Python code; Decimal-to-float
4190 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004191
Georg Brandlba83f822010-03-14 09:50:54 +00004192 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4193 providing correctly-rounded strtod and dtoa C functions. This code is
4194 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4195 the C compiler. There may be a small number of platforms on which correct
4196 operation of this code cannot be guaranteed, so the code is not used: notably,
4197 this applies to platforms where the C double format is not IEEE 754 binary64,
4198 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4199 and Python's configure script is unable to determine how to change the FPU
4200 precision. On these platforms conversions use the platform strtod and dtoa,
4201 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004202
Georg Brandlba83f822010-03-14 09:50:54 +00004203- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4204 uses the correctly-rounded string <-> float conversions described above (when
4205 available), and so produces correctly rounded results that will display nicely
4206 under the float repr. There are two related small changes: (1) round now
4207 accepts any class with an ``__index__()`` method for its second argument (but
4208 no longer accepts floats for the second argument), and (2) an excessively
4209 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4210 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00004352
Georg Brandlba83f822010-03-14 09:50:54 +00004353 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
4354 (2) parsing of strings representing infinities and nans was locale aware; and
4355 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00004357- Issue #5920: For ``float.__format__()``, change the behavior with the empty
4358 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
4359 but with at least one decimal point and with a default precision
4360 of 12. Previously, the behavior the same but with a default precision of 6.
4361 This more closely matches ``str()``, and reduces surprises when adding
4362 alignment flags to the empty presentation type. This also affects the new
4363 complex.__format__ in the same way.
4364
4365- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

4437 internal representation of integers, for performance reasons. Base 2**30 is
4438 enabled by default on 64-bit machines. Add --enable-big-digits option to

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00005991- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
5992
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005993- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5994 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5995 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5996 ``printf`` function, whereas PyString_FromFormat has an independent
5997 implementation and uses "%zd" on all platforms for size_t values.
5998 This makes a difference on win64, where ``printf`` needs "%Id" to display
5999 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00006001- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00006004- Issue #3777: long() applied to a float object now always return a long
6005 object; previously an int would be returned for small values. the __long__
6006 method is allowed to return either an int or a long, but the behaviour of
6007 float objects should not change to respect backward compatibility.
6008
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00006009- Issue #3751: str.rpartition would perform a left-partition when called with
6010 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +00006015 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006016 was correctly parsed but parsing of subsequent arguments failed.
6017
Vinay Sajip35e3b032008-09-01 14:33:59 +00006018- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006019 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6020 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6021 when given a tuple of classes as second argument, were looking up
6022 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6023 type object.
6024
Neal Norwitz18aa3882008-08-24 05:04:52 +00006025- Fix crashes on memory allocation failure found with failmalloc.

Brett Cannon1eaf0742008-09-02 01:25:16 +00006094 warnings.catch_warnings() along with some API cleanup. Expanding the tests
6095 for catch_warnings() also led to an improvement in the raising of a

6168-----------------
6169
Guido van Rossumf8402962008-08-20 15:01:50 +00006170- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6171 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6172 extensions do not automatically benefit from the class attribute
6173 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6174 to their tp_flags field if they care. This is a backwards
6175 compatibility feature; in 3.0, all types will use the cache by
6176 default.
6177
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006178- Keyword arguments can now follow starred arguments. (``f(a, *args,
6179 keyword=23)`` is now valid syntax.)
6180
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006181- ctypes function pointers that are COM methods have a boolean True
6182 value again.
6183
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006184- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6185 by denying s# to parse objects that have a releasebuffer procedure,
6186 and introducing s*.
6187
Georg Brandl1e13ea92008-08-11 09:07:59 +00006188- Issue #3537: Fix an assertion failure when an empty but presized dict
6189 object was stored in the freelist.
6190
Mark Dickinsonb6467572008-08-04 21:30:09 +00006191- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6192 ValueError consistently across platforms.
6193
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006194- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6195 (64bit Unix, for example), unichr() would truncate its argument and return
6196 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6197
Neal Norwitze7d8be82008-07-31 17:17:14 +00006198- Apply security patches from Apple.
6199
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006200- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6201 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6202
Antoine Pitrou92f82162008-07-25 22:22:08 +00006203- Issue #1819: function calls with several named parameters are now on
6204 average 35% faster (as measured by pybench).
6205
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006206- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6207 the python debugger steps into a class statement: the free variables (local
6208 variables defined in an outer scope) would be deleted from the outer scope.
6209
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006210- Issue #2620: Overflow checking when allocating or reallocating memory
6211 was not always being done properly in some python types and extension
6212 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6213 all been updated to perform better checks and places in the code that
6214 would previously leak memory on the error path when such an allocation
6215 failed have been fixed.

6221
Benjamin Petersone977ad42008-08-20 01:42:01 +00006222- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6223 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6224
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006225- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6226 version reported by these tools does not necessarily follow the python
6227 version numbering scheme, so the module is less strict when parsing it.
6228
Nick Coghlanf70385a2008-08-18 12:42:46 +00006229- Issue #2235: Added Py3k warnings for types which will become unhashable
6230 under the stricter __hash__ inheritance rules in 3.0. Several types

Antoine Pitroude781a42008-08-09 12:43:23 +00006305 asking for a specific length. This problem only affected files opened

6348 interaction with the tp_hash slot (added in 2.6b2) are now documented
6349
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00006350- Issue #643841: The language reference now provides more detailed

6357================================
6358
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006359*Release date: 17-Jul-2008*
6360
Raymond Hettingere3ae6552008-06-20 04:18:15 +00006361Core and Builtins
6362-----------------
6363
Georg Brandl3e483f62008-07-16 22:57:41 +00006364- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6365 its methods now allow for items objects that can be converted to
6366 an integer using operator.index().
6367
Mark Dickinson64b7e502008-07-16 09:40:03 +00006368- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6369 produced a ValueError instead of giving the correct float.
6370
Eric Smitha5fa5a22008-07-16 00:11:49 +00006371- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6372 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6373
Mark Dickinson7103aa42008-07-15 19:08:33 +00006374- Issue #3008: the float type has a new instance method 'float.hex'
6375 and a new class method 'float.fromhex' to convert floating-point
6376 numbers to and from hexadecimal strings, respectively.
6377
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006378- Issue #2235: __hash__ is once again inherited by default. To allow
6379 collections.Hashable to remain meaningful in the presence of the
6380 default hash implementation (object.__hash__), it is now possible
6381 to explicit block inheritance of hash by setting __hash__=None at
6382 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6383 level.
6384
Nick Coghlanb028f502008-07-13 14:52:36 +00006385- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6386 the parent module cannot be found while performing an absolute import.
6387 This means that an incorrectly defined __package__ attribute will
6388 now only prevent relative imports in that module rather than causing
6389 all imports from that module to fail.
6390
Nick Coghlan14ff9942008-07-08 14:21:42 +00006391- Issue #2517: Allow unicode messages in Exceptions again by correctly
6392 bypassing the instance dictionary when looking up __unicode__ on
6393 new-style classes.
6394
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00006395- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
6396 set to a custom object whose write() method happens to install
6397 another file in sys.stdout.
6398
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00006399- Issue #3088: Corrected a race condition in classes derived from
6400 threading.local: the first member set by a thread could be saved in
6401 another thread's dictionary.
6402
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006403- Issue #3004: Minor change to slice.indices(): the start and stop
6404 arguments are now treated identically, making the behaviour easier
6405 to describe and understand. For example, slice(None, -10,
6406 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6407 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6408 10, -1).
6409
Georg Brandl278fc502008-07-19 12:46:12 +00006410- Issue #3219: Calling a function with repeated keyword arguments,
6411 f(a=2, a=23), would not cause a syntax error. This was a regression
6412 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00006413
Georg Brandl278fc502008-07-19 12:46:12 +00006414- Issue #2862: Make int and float freelist management consistent with
6415 other freelists. Changes their CompactFreeList apis into
6416 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00006417

6419-------
6420
Thomas Heller57adf222008-08-14 19:10:48 +00006421- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
6422 api functions without holding the GIL, which could lead to a fatal
6423 error when they failed.
6424
Martin v. Löwisaabf4042008-08-02 07:20:25 +00006425- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

6434 ForkingPickler.register() to resolve conflict with ctypes.
6435
Vinay Sajip51e65192008-07-18 09:01:10 +00006436- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Raymond Hettinger3cd1e422008-07-10 14:03:19 +00006449
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006450- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
6451 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006452 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006453 content-length. The problem had been corrected in the 2.4 branch, but never
6454 merged into trunk.
6455

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006467 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00006468
Nick Coghlanc060b0e2008-07-02 13:09:19 +00006469- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
6470 handling is now the same as that of other special attributes like __name__).
6471
Brett Cannon8bb8fa52008-07-02 01:57:08 +00006472- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Ronald Oussoren5640ce22008-06-05 12:58:24 +00006860- On MacOS X it is now possible to install the framework in 64-bit
6861 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00006862 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006863
6864 This is controlled by the configure argument ``--with-universal-archs``:
6865
6866 - ``--with-universal-archs=all``: install 4-way universal
6867
6868 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6869
6870 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6871
6872 This option should be used in combination with ``--enable-universalsdk=``.
6873
6874 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 +00006924- Issue #1631171: Re-implement the 'warnings' module in C (the
6925 original Python code has been kept as backup). This will allow for
6926 using the 'warning's machinery in such places as the parser where
6927 use of pure Python code is not possible. Both the ``showarning()``
6928 and ``formatwarning()`` gain an optional 'line' argument which is
6929 not called by default for backwards-compatibility reasons. Setting
6930 ``warnings.showwarning()`` to an implementation that lacks support
6931 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006994- Issue #2550: The approach used by client/server code for obtaining
6995 ports to listen on in network-oriented tests has been refined in an
6996 effort to facilitate running multiple instances of the entire
6997 regression test suite in parallel without issue.
6998 test_support.bind_port() has been fixed such that it will always
6999 return a unique port -- which wasn't always the case with the
7000 previous implementation, especially if socket options had been set
7001 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7002 new implementation of bind_port() will actually raise an exception
7003 if it is passed an AF_INET/SOCK_STREAM socket with either the
7004 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7005 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7006 the socket it's been passed. This currently only applies to
7007 Windows. This option prevents any other sockets from binding to the
7008 host/port we've bound to, thus removing the possibility of the
7009 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7010 when a second SOCK_STREAM socket binds and accepts to a host/port
7011 that's already been bound by another socket. The optional preferred
7012 port parameter to bind_port() has been removed. Under no
7013 circumstances should tests be hard coding ports!
7014
7015 test_support.find_unused_port() has also been introduced, which will
7016 pass a temporary socket object to bind_port() in order to obtain an
7017 unused port. The temporary socket object is then closed and
7018 deleted, and the port is returned. This method should only be used
7019 for obtaining an unused port in order to pass to an external program
7020 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7021 a parameter to a server-oriented class that doesn't give you direct
7022 access to the underlying socket used.
7023
7024 Finally, test_support.HOST has been introduced, which should be used
7025 for the host argument of any relevant socket calls (i.e. bind and
7026 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007027
7028 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007029 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007030 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7031 test_asynchat and test_socket_ssl.
7032
Georg Brandl3ee81df2008-05-17 18:14:43 +00007033 It is now possible for multiple instances of the regression test
7034 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00007088- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00007089 \Uxxxxxxxx did not accept values outside the Basic Multilingual
7090 Plane. This affected raw unicode literals and the
7091 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
7092 this case, like normal unicode literals and the 'unicode-escape'
7093 codec.

Eric Smitha73fbe72008-02-23 03:09:44 +00007313- Added the future_builtins module, which contains hex() and oct().
7314 These are the PEP 3127 version of these functions, designed to be
7315 compatible with the hex() and oct() builtins from Python 3.0. They
7316 differ slightly in their output formats from the existing, unchanged
7317 Python 2.6 builtins. The expected usage of the future_builtins
7318 module is:

7320
Eric Smith7ef40bf2008-02-20 23:34:22 +00007321- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7322 exponents for exponents with absolute value < 100. Follows C99
7323 standard. This is a change on Windows, which would use 3 digits.
7324 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7325 so that any alterations it does to the resulting string will be
7326 available in stringlib/formatter.h (for float.__format__).
7327
Eric Smith5a3c1352008-02-19 13:21:56 +00007328- Implemented PEP 3101, Advanced String Formatting. This adds a new
7329 builtin format(); a format() method for str and unicode; a
7330 __format__() method to object, str, unicode, int, long, float, and
7331 datetime; the class string.Formatter; and the C API
7332 PyObject_Format().
7333
Georg Brandl3ee81df2008-05-17 18:14:43 +00007334- Fixed several potential crashes, all caused by specially crafted
7335 __del__ methods exploiting objects in temporarily inconsistent
7336 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00007337
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007338- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00007339 prevent a possible crash: an Abstract Base Class would try to access
7340 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00007341

Georg Brandl3ee81df2008-05-17 18:14:43 +00007345- Clear all free lists during a gc.collect() of the highest generation
7346 in order to allow pymalloc to free more arenas. Python may give back
7347 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007348
Georg Brandl3ee81df2008-05-17 18:14:43 +00007349- Issue #2045: Fix an infinite recursion triggered when printing a
7350 subclass of collections.defaultdict, if its default_factory is set
7351 to a bound method.

Christian Heimesf75dbef2008-02-08 00:11:31 +00007353- Fixed a minor memory leak in dictobject.c. The content of the free
7354 list was not freed on interpreter shutdown.
7355
Georg Brandl21e99f42010-03-07 15:23:59 +00007356- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00007357 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00007358

Georg Brandl3ee81df2008-05-17 18:14:43 +00007379- Patch #1473257: generator objects gain a gi_code attribute. This is
7380 the same object as the func_code attribute of the function that
7381 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007382
Georg Brandl3ee81df2008-05-17 18:14:43 +00007383- Issue #1920: "while 0" statements were completely removed by the
7384 compiler, even in the presence of an "else" clause, which is
7385 supposed to be run when the condition is false. Now the compiler
7386 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007387
Guido van Rossumeead05f2008-01-24 18:21:02 +00007388- A few crashers fixed: weakref_in_del.py (issue #1377858);
7389 loosing_dict_ref.py (issue #1303614, test67.py);
7390 borrowed_ref_[34].py (not in tracker).
7391
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00007392- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00007393 suppressed while an extension is loaded by calling SetErrorMode in
7394 dynload_win.c. The error is still reported properly.
7395
Georg Brandl3ee81df2008-05-17 18:14:43 +00007396- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007397 several extension methods and modules do not work without unicode
7398 support.
7399
Georg Brandl26543b12008-01-21 18:36:51 +00007400- Issue #1882: when compiling code from a string, encoding cookies in the

7404
Georg Brandl6caad7d2008-01-26 14:19:22 +00007405- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007406 added.
7407
Christian Heimesc94e2b52008-01-14 04:13:37 +00007408- sys.float_info / PyFloat_GetInfo: The floating point information
7409 object was converted from a dict to a specialized structseq object.
7410
Georg Brandl3ee81df2008-05-17 18:14:43 +00007411- Patch #1816: Added sys.flags structseq. It exposes the status of
7412 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007413
Georg Brandl3ee81df2008-05-17 18:14:43 +00007414- Objects/structseq.c: Implemented new structseq representation. The
7415 patch makes structseqs (e.g. the return value of os.stat) more
7416 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007417
Georg Brandl3ee81df2008-05-17 18:14:43 +00007418- Patch #1700288: added a type attribute cache that caches method
7419 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00007420
Neal Norwitz3fc15b82008-01-10 05:42:58 +00007421- Bug #1776: __import__() no longer accepts filenames on any platform.

7427 envvar and sys.dont_write_bytecode attribute. All these can be set
7428 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007429
Georg Brandl3ee81df2008-05-17 18:14:43 +00007430- Improve some exception messages when Windows fails to load an
7431 extension module. Now we get for example '%1 is not a valid Win32
7432 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00007439- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00007440 and INF. float("nan"), float("inf") and float("-inf") now work on
7441 every platform with IEEE 754 semantics.

7489
Georg Brandl21e99f42010-03-07 15:23:59 +00007490- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007491 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7492 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007493
Georg Brandl3ee81df2008-05-17 18:14:43 +00007494- Issue #1686386: Tuple's tp_repr did not take into account the
7495 possibility of having a self-referential tuple, which is possible
7496 from C code. Nor did object's tp_str consider that a type's tp_str
7497 could do something that could lead to an inifinite recursion.
7498 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7499 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007500
Georg Brandl3ee81df2008-05-17 18:14:43 +00007501- Issue #1164: It was possible to trigger deadlock when using the
7502 'print' statement to write to a file since the GIL was not released
7503 as needed. Now PyObject_Print() does the right thing along with
7504 various tp_print implementations of the built-in types and those in
7505 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007506
Georg Brandl3ee81df2008-05-17 18:14:43 +00007507- Issue #1147: Exceptions were directly allowing string exceptions in

Georg Brandl3ee81df2008-05-17 18:14:43 +00007515 PyObject_Call() never calling back out to Python code to trigger
7516 recursion depth updates/checks. Required the creation of a static
7517 RuntimeError instance in case normalizing an exception put the
7518 recursion check value past its limit. Fixes crashers

Georg Brandl5cb76c12007-03-21 09:00:39 +00007562- Patch #1682205: a TypeError while unpacking an iterable is no longer
7563 masked by a generic one with the message "unpack non-sequence".

7566
Guido van Rossum143b5642007-03-23 04:58:42 +00007567- Bug #1683368: The object.__init__() and object.__new__() methods are
7568 now stricter in rejecting excess arguments. The only time when
7569 either allows excess arguments is when it is not overridden and the
7570 other one is. For backwards compatibility, when both are
7571 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007572 warning later). Also, type.__init__() insists on the same signature
7573 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00007575- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7576 object to complex using its __complex__() method before falling back
7577 to the __float__() method. Therefore, the functions in the cmath
7578 module now can operate on objects that define a __complex__()
7579 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00007597- Bug #1678647: write a newline after printing an exception in any
7598 case, even when converting the value to a string failed.
7599
Georg Brandl871f1bc2007-03-12 13:17:36 +00007600- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007601 its argument, if it exists. If not, it will work like before. This
7602 allows customizing the output of dir() in the presence of a
7603 __getattr__().

7613 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00007614
Georg Brandlaa2321b2007-03-07 00:40:28 +00007615- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007616 makes the filenames the warning module prints much more sensible
7617 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00007630- Patch #1674228: when assigning a slice (old-style), check for the
7631 sq_ass_slice instead of the sq_slice slot.
7632
Georg Brandl3ee81df2008-05-17 18:14:43 +00007633- When printing an unraisable error, don't print exceptions. before
7634 the name. This duplicates the behavior whening normally printing
7635 exceptions.

7644 created a weakref on itself during a __del__ call for new-style
7645 classes (classic classes still have the bug).

Georg Brandl2c1375c2006-10-12 11:27:59 +00007685- Bug #1545497: when given an explicit base, int() did ignore NULs
7686 embedded in the string to convert.
7687
Georg Brandl846f73a2006-10-08 07:11:54 +00007688- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl4e933132006-09-06 20:05:58 +00007718- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007736 generator expressions (x for x, in ... ) works again. Fixing this
7737 problem required changing the .pyc magic number. This means that
7738 .pyc files generated before 2.5c2 will be regenerated.

8539 longer than 3 bytes.
Georg Brandl27562782006-10-27 20:39:43 +00008540
Georg Brandl3ee81df2008-05-17 18:14:43 +00008541- The implementation of UnicodeError objects has been simplified
8542 (start and end attributes are now stored directly as Py_ssize_t
8543 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00008544
Georg Brandl3ee81df2008-05-17 18:14:43 +00008545- Issue #829951: In the smtplib module, SMTP.starttls() now complies
8546 with RFC 3207 and forgets any knowledge obtained from the server not
8547 obtained from the TLS negotiation itself. Patch contributed by Bill
8548 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00008549
Georg Brandl3ee81df2008-05-17 18:14:43 +00008550- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00008551 that the SMTP.starttls() caller no longer needs to call ehlo()
8552 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00008553 does not claim to support starttls. Adds the
8554 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
8555 Fenner.

8624 contents before adding elements from the iterable. This fix brings
8625 the behavior into line with that for list.__init__().
Raymond Hettingeradf9ffd2007-12-13 00:08:37 +00008626
Georg Brandl3ee81df2008-05-17 18:14:43 +00008627- Added wide char functions to msvcrt module: getwch, getwche, putwch

8633
Georg Brandl3ee81df2008-05-17 18:14:43 +00008634- Marshal.dumps() now expects exact type matches for int, long, float,
8635 complex, tuple, list, dict, set, and frozenset. Formerly, it would
8636 silently miscode subclasses of those types. Now, it raises a
8637 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00008638

Georg Brandl3ee81df2008-05-17 18:14:43 +00008653 time so that opening a database previously created with the DB_DUP
8654 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8655 opens. Specifically: dictionary assignment to a DB object will
8656 replace all values for a given key when the database allows
8657 duplicate values. DB users should use DB.put(k, v) when they want
8658 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00008659

8665 characters with ASCII value less than 32. Also, it correctly quotes
8666 dots only if they occur on a single line, as opposed to the previous
8667 behavior of quoting dots if they are the second character of any
8668 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00008669

8698 negative numbers, per the underlying C implementation.
Guido van Rossumbb2cc692007-01-14 17:03:32 +00008699

Georg Brandl3ee81df2008-05-17 18:14:43 +00009074- Removed the macfs module. It had been deprecated since Python 2.5.
9075 This lead to the deprecation of macostools.touched() as it relied
9076 solely on macfs and was a no-op under OS X.
