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

Florent Xiclunac2279652012-02-12 14:49:03 +01001236- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01001237 has left two versions of customize_compiler, the original in
1238 distutils.sysconfig and another copy in distutils.ccompiler, with some
1239 parts of distutils calling one and others using the other.

1241 is the case in 3.x.
1242
Ned Deily0d0ea482012-02-10 12:59:06 +01001243- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1244 Distutils-based packages with C extension modules may fail because
1245 Apple has removed gcc-4.2, the version used to build python.org
1246 64-bit/32-bit Pythons. If the user does not explicitly override
1247 the default C compiler by setting the CC environment variable,
1248 Distutils will now attempt to compile extension modules with clang
1249 if gcc-4.2 is required but not found. Also as a convenience, if
1250 the user does explicitly set CC, substitute its value as the default
1251 compiler in the Distutils LDSHARED configuration variable for OS X.
1252 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1253 SDK, neither of which are available in Xcode 4. This change does not
1254 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001527- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1528 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1529 interpreter process. This could cause failures in non-Distutils subprocesses
1530 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02001531 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07001532 deployment target only in the environment of each build subprocess. It is
1533 still possible to globally override the default by setting
1534 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1535 greater or equal to the default value, the value with which the interpreter
1536 was built.

1565 updating the check interval, so if the user decreases the check interval,
1566 the ticker doesn't have to wind down to zero from the old starting point
1567 before the new interval takes effect. And if the user increases the
1568 interval, it makes sure the new limit takes effect right away rather have an
1569 early task switch before recognizing the new interval.

2519
Raymond Hettinger20397532010-09-12 02:11:45 +00002520- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
2521 This prevents user-created self-referencing ordered dictionaries from
2522 becoming permanently uncollectable GC garbage. The downside is that
2523 removing __del__ means that the internal doubly-linked list has to wait for
2524 GC collection rather than freeing memory immediately when the refcnt drops
2525 to zero.

2530
Antoine Pitrouc818ed42010-09-07 21:40:25 +00002531- Issue #9792: In case of connection failure, socket.create_connection()

2533 to fetch the original errno, or to filter timeout errors. Now the
2534 original error is re-raised.

2555
R. David Murray7c4bf552010-08-25 01:45:57 +00002556- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four

2983
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00002984- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
2985 start byte and the continuation byte(s) are now considered invalid, instead
2986 of the number of bytes specified by the start byte.
2987 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
2988 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
2989 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00002998- Issue #8748: Fix two issues with comparisons between complex and integer
2999 objects. (1) The comparison could incorrectly return True in some cases
3000 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
3001 (2) The comparison raised an OverflowError for large integers, leading
3002 to unpredictable exceptions when combining integers and complex objects
3003 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +00003005- Issue #5211: Implicit coercion for the complex type is now completely

Georg Brandlba83f822010-03-14 09:50:54 +00003883 file position when calling `truncate()`. It would previously change the file
3884 position to the given argument, which goes against the tradition of

3888 class used to represent files stored inside an archive. The new
3889 implementation is significantly faster and can be wrapped in a
3890 ``io.BufferedReader`` object for more speedups. It also solves an issue
3891 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

3987
Mark Dickinson1b34d252010-01-01 17:27:30 +00003988- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00003989 DeprecationWarning when passed a float argument where an integer was expected.
3990 These functions and methods now raise TypeError instead. The majority of the
3991 effects of this change are in the extension modules, but some core functions
3992 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3993 and many unicode/str methods.

4009 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +00004105- Issue #5080: The argument parsing functions ``PyArg_ParseTuple()``,
4106 ``PyArg_ParseTupleAndKeywords()``, ``PyArg_VaParse()``,
4107 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept
4108 float arguments for integer format codes (other than 'L'): previously an
4109 attempt to pass a float resulted in a DeprecationWarning; now it gives a
4110 TypeError. For the 'L' format code (which previously had no warning) there is
4111 now a DeprecationWarning.

4159 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
4160 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00004161
Georg Brandlba83f822010-03-14 09:50:54 +00004162- Remove switch from "%f" formatting to "%g" formatting for floats larger than
4163 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00004164
Georg Brandlba83f822010-03-14 09:50:54 +00004165- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
4166 1e-100 used to raise OverflowError, but now gives the requested 120
4167 significant digits instead.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00004175
Georg Brandlba83f822010-03-14 09:50:54 +00004176- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4177 decimal string that's guaranteed to round back to x under correct rounding
4178 (with round-half-to-even rounding mode). Previously it gave a string based on
4179 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4180 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4181 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004182
Georg Brandlba83f822010-03-14 09:50:54 +00004183- Issue #7117: On almost all platforms: float-to-string and string-to-float
4184 conversions within Python are now correctly rounded. Places these conversions
4185 occur include: str for floats and complex numbers; the float and complex
4186 constructors; old-style and new-style numeric formatting; serialization and
4187 deserialization of floats and complex numbers using marshal, pickle and json;
4188 parsing of float and imaginary literals in Python code; Decimal-to-float
4189 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004190
Georg Brandlba83f822010-03-14 09:50:54 +00004191 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4192 providing correctly-rounded strtod and dtoa C functions. This code is
4193 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4194 the C compiler. There may be a small number of platforms on which correct
4195 operation of this code cannot be guaranteed, so the code is not used: notably,
4196 this applies to platforms where the C double format is not IEEE 754 binary64,
4197 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4198 and Python's configure script is unable to determine how to change the FPU
4199 precision. On these platforms conversions use the platform strtod and dtoa,
4200 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004201
Georg Brandlba83f822010-03-14 09:50:54 +00004202- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4203 uses the correctly-rounded string <-> float conversions described above (when
4204 available), and so produces correctly rounded results that will display nicely
4205 under the float repr. There are two related small changes: (1) round now
4206 accepts any class with an ``__index__()`` method for its second argument (but
4207 no longer accepts floats for the second argument), and (2) an excessively
4208 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4209 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00004351
Georg Brandlba83f822010-03-14 09:50:54 +00004352 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
4353 (2) parsing of strings representing infinities and nans was locale aware; and
4354 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00004356- Issue #5920: For ``float.__format__()``, change the behavior with the empty
4357 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
4358 but with at least one decimal point and with a default precision
4359 of 12. Previously, the behavior the same but with a default precision of 6.
4360 This more closely matches ``str()``, and reduces surprises when adding
4361 alignment flags to the empty presentation type. This also affects the new
4362 complex.__format__ in the same way.
4363
4364- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

4436 internal representation of integers, for performance reasons. Base 2**30 is
4437 enabled by default on 64-bit machines. Add --enable-big-digits option to

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00005990- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
5991
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005992- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5993 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5994 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5995 ``printf`` function, whereas PyString_FromFormat has an independent
5996 implementation and uses "%zd" on all platforms for size_t values.
5997 This makes a difference on win64, where ``printf`` needs "%Id" to display
5998 64bit values.
5999
Benjamin Peterson97179b02008-09-09 20:55:01 +00006000- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
6001 error.
6002
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00006003- Issue #3777: long() applied to a float object now always return a long
6004 object; previously an int would be returned for small values. the __long__
6005 method is allowed to return either an int or a long, but the behaviour of
6006 float objects should not change to respect backward compatibility.
6007
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00006008- Issue #3751: str.rpartition would perform a left-partition when called with
6009 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +00006014 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006015 was correctly parsed but parsing of subsequent arguments failed.
6016
Vinay Sajip35e3b032008-09-01 14:33:59 +00006017- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006018 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6019 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6020 when given a tuple of classes as second argument, were looking up
6021 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6022 type object.
6023
Neal Norwitz18aa3882008-08-24 05:04:52 +00006024- Fix crashes on memory allocation failure found with failmalloc.

Brett Cannon1eaf0742008-09-02 01:25:16 +00006093 warnings.catch_warnings() along with some API cleanup. Expanding the tests
6094 for catch_warnings() also led to an improvement in the raising of a

6167-----------------
6168
Guido van Rossumf8402962008-08-20 15:01:50 +00006169- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6170 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6171 extensions do not automatically benefit from the class attribute
6172 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6173 to their tp_flags field if they care. This is a backwards
6174 compatibility feature; in 3.0, all types will use the cache by
6175 default.
6176
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006177- Keyword arguments can now follow starred arguments. (``f(a, *args,
6178 keyword=23)`` is now valid syntax.)
6179
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006180- ctypes function pointers that are COM methods have a boolean True
6181 value again.
6182
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006183- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6184 by denying s# to parse objects that have a releasebuffer procedure,
6185 and introducing s*.
6186
Georg Brandl1e13ea92008-08-11 09:07:59 +00006187- Issue #3537: Fix an assertion failure when an empty but presized dict
6188 object was stored in the freelist.
6189
Mark Dickinsonb6467572008-08-04 21:30:09 +00006190- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6191 ValueError consistently across platforms.
6192
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006193- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6194 (64bit Unix, for example), unichr() would truncate its argument and return
6195 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6196
Neal Norwitze7d8be82008-07-31 17:17:14 +00006197- Apply security patches from Apple.
6198
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006199- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6200 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6201
Antoine Pitrou92f82162008-07-25 22:22:08 +00006202- Issue #1819: function calls with several named parameters are now on
6203 average 35% faster (as measured by pybench).
6204
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006205- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6206 the python debugger steps into a class statement: the free variables (local
6207 variables defined in an outer scope) would be deleted from the outer scope.
6208
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006209- Issue #2620: Overflow checking when allocating or reallocating memory
6210 was not always being done properly in some python types and extension
6211 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6212 all been updated to perform better checks and places in the code that
6213 would previously leak memory on the error path when such an allocation
6214 failed have been fixed.

6220
Benjamin Petersone977ad42008-08-20 01:42:01 +00006221- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6222 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6223
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006224- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6225 version reported by these tools does not necessarily follow the python
6226 version numbering scheme, so the module is less strict when parsing it.
6227
Nick Coghlanf70385a2008-08-18 12:42:46 +00006228- Issue #2235: Added Py3k warnings for types which will become unhashable
6229 under the stricter __hash__ inheritance rules in 3.0. Several types

Antoine Pitroude781a42008-08-09 12:43:23 +00006304 asking for a specific length. This problem only affected files opened

6347 interaction with the tp_hash slot (added in 2.6b2) are now documented
6348
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00006349- Issue #643841: The language reference now provides more detailed

6356================================
6357
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006358*Release date: 17-Jul-2008*
6359
Raymond Hettingere3ae6552008-06-20 04:18:15 +00006360Core and Builtins
6361-----------------
6362
Georg Brandl3e483f62008-07-16 22:57:41 +00006363- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6364 its methods now allow for items objects that can be converted to
6365 an integer using operator.index().
6366
Mark Dickinson64b7e502008-07-16 09:40:03 +00006367- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6368 produced a ValueError instead of giving the correct float.
6369
Eric Smitha5fa5a22008-07-16 00:11:49 +00006370- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6371 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6372
Mark Dickinson7103aa42008-07-15 19:08:33 +00006373- Issue #3008: the float type has a new instance method 'float.hex'
6374 and a new class method 'float.fromhex' to convert floating-point
6375 numbers to and from hexadecimal strings, respectively.
6376
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006377- Issue #2235: __hash__ is once again inherited by default. To allow
6378 collections.Hashable to remain meaningful in the presence of the
6379 default hash implementation (object.__hash__), it is now possible
6380 to explicit block inheritance of hash by setting __hash__=None at
6381 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6382 level.
6383
Nick Coghlanb028f502008-07-13 14:52:36 +00006384- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6385 the parent module cannot be found while performing an absolute import.
6386 This means that an incorrectly defined __package__ attribute will
6387 now only prevent relative imports in that module rather than causing
6388 all imports from that module to fail.
6389
Nick Coghlan14ff9942008-07-08 14:21:42 +00006390- Issue #2517: Allow unicode messages in Exceptions again by correctly
6391 bypassing the instance dictionary when looking up __unicode__ on
6392 new-style classes.
6393
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00006394- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
6395 set to a custom object whose write() method happens to install
6396 another file in sys.stdout.
6397
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00006398- Issue #3088: Corrected a race condition in classes derived from
6399 threading.local: the first member set by a thread could be saved in
6400 another thread's dictionary.
6401
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006402- Issue #3004: Minor change to slice.indices(): the start and stop
6403 arguments are now treated identically, making the behaviour easier
6404 to describe and understand. For example, slice(None, -10,
6405 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6406 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6407 10, -1).
6408
Georg Brandl278fc502008-07-19 12:46:12 +00006409- Issue #3219: Calling a function with repeated keyword arguments,
6410 f(a=2, a=23), would not cause a syntax error. This was a regression
6411 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00006412
Georg Brandl278fc502008-07-19 12:46:12 +00006413- Issue #2862: Make int and float freelist management consistent with
6414 other freelists. Changes their CompactFreeList apis into
6415 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00006416

Thomas Heller57adf222008-08-14 19:10:48 +00006420- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
6421 api functions without holding the GIL, which could lead to a fatal
6422 error when they failed.
6423
Martin v. Löwisaabf4042008-08-02 07:20:25 +00006424- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

6433 ForkingPickler.register() to resolve conflict with ctypes.
6434
Vinay Sajip51e65192008-07-18 09:01:10 +00006435- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Raymond Hettinger3cd1e422008-07-10 14:03:19 +00006448
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006449- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
6450 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006451 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006452 content-length. The problem had been corrected in the 2.4 branch, but never
6453 merged into trunk.

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006466 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00006467
Nick Coghlanc060b0e2008-07-02 13:09:19 +00006468- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
6469 handling is now the same as that of other special attributes like __name__).
6470
Brett Cannon8bb8fa52008-07-02 01:57:08 +00006471- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Ronald Oussoren5640ce22008-06-05 12:58:24 +00006859- On MacOS X it is now possible to install the framework in 64-bit
6860 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00006861 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006862
6863 This is controlled by the configure argument ``--with-universal-archs``:
6864
6865 - ``--with-universal-archs=all``: install 4-way universal
6866
6867 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6868
6869 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6870
6871 This option should be used in combination with ``--enable-universalsdk=``.
6872
6873 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 +00006923- Issue #1631171: Re-implement the 'warnings' module in C (the
6924 original Python code has been kept as backup). This will allow for
6925 using the 'warning's machinery in such places as the parser where
6926 use of pure Python code is not possible. Both the ``showarning()``
6927 and ``formatwarning()`` gain an optional 'line' argument which is
6928 not called by default for backwards-compatibility reasons. Setting
6929 ``warnings.showwarning()`` to an implementation that lacks support
6930 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006993- Issue #2550: The approach used by client/server code for obtaining
6994 ports to listen on in network-oriented tests has been refined in an
6995 effort to facilitate running multiple instances of the entire
6996 regression test suite in parallel without issue.
6997 test_support.bind_port() has been fixed such that it will always
6998 return a unique port -- which wasn't always the case with the
6999 previous implementation, especially if socket options had been set
7000 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7001 new implementation of bind_port() will actually raise an exception
7002 if it is passed an AF_INET/SOCK_STREAM socket with either the
7003 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7004 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7005 the socket it's been passed. This currently only applies to
7006 Windows. This option prevents any other sockets from binding to the
7007 host/port we've bound to, thus removing the possibility of the
7008 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7009 when a second SOCK_STREAM socket binds and accepts to a host/port
7010 that's already been bound by another socket. The optional preferred
7011 port parameter to bind_port() has been removed. Under no
7012 circumstances should tests be hard coding ports!
7013
7014 test_support.find_unused_port() has also been introduced, which will
7015 pass a temporary socket object to bind_port() in order to obtain an
7016 unused port. The temporary socket object is then closed and
7017 deleted, and the port is returned. This method should only be used
7018 for obtaining an unused port in order to pass to an external program
7019 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7020 a parameter to a server-oriented class that doesn't give you direct
7021 access to the underlying socket used.
7022
7023 Finally, test_support.HOST has been introduced, which should be used
7024 for the host argument of any relevant socket calls (i.e. bind and
7025 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007026
7027 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007028 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007029 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7030 test_asynchat and test_socket_ssl.
7031
Georg Brandl3ee81df2008-05-17 18:14:43 +00007032 It is now possible for multiple instances of the regression test
7033 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00007087- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00007088 \Uxxxxxxxx did not accept values outside the Basic Multilingual
7089 Plane. This affected raw unicode literals and the
7090 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
7091 this case, like normal unicode literals and the 'unicode-escape'
7092 codec.

Eric Smitha73fbe72008-02-23 03:09:44 +00007312- Added the future_builtins module, which contains hex() and oct().
7313 These are the PEP 3127 version of these functions, designed to be
7314 compatible with the hex() and oct() builtins from Python 3.0. They
7315 differ slightly in their output formats from the existing, unchanged
7316 Python 2.6 builtins. The expected usage of the future_builtins
7317 module is:

Eric Smith7ef40bf2008-02-20 23:34:22 +00007320- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7321 exponents for exponents with absolute value < 100. Follows C99
7322 standard. This is a change on Windows, which would use 3 digits.
7323 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7324 so that any alterations it does to the resulting string will be
7325 available in stringlib/formatter.h (for float.__format__).
7326
Eric Smith5a3c1352008-02-19 13:21:56 +00007327- Implemented PEP 3101, Advanced String Formatting. This adds a new
7328 builtin format(); a format() method for str and unicode; a
7329 __format__() method to object, str, unicode, int, long, float, and
7330 datetime; the class string.Formatter; and the C API
7331 PyObject_Format().
7332
Georg Brandl3ee81df2008-05-17 18:14:43 +00007333- Fixed several potential crashes, all caused by specially crafted
7334 __del__ methods exploiting objects in temporarily inconsistent
7335 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00007336
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007337- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00007338 prevent a possible crash: an Abstract Base Class would try to access
7339 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00007340

Georg Brandl3ee81df2008-05-17 18:14:43 +00007344- Clear all free lists during a gc.collect() of the highest generation
7345 in order to allow pymalloc to free more arenas. Python may give back
7346 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007347
Georg Brandl3ee81df2008-05-17 18:14:43 +00007348- Issue #2045: Fix an infinite recursion triggered when printing a
7349 subclass of collections.defaultdict, if its default_factory is set
7350 to a bound method.

Christian Heimesf75dbef2008-02-08 00:11:31 +00007352- Fixed a minor memory leak in dictobject.c. The content of the free
7353 list was not freed on interpreter shutdown.
7354
Georg Brandl21e99f42010-03-07 15:23:59 +00007355- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00007356 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00007357

Georg Brandl3ee81df2008-05-17 18:14:43 +00007378- Patch #1473257: generator objects gain a gi_code attribute. This is
7379 the same object as the func_code attribute of the function that
7380 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007381
Georg Brandl3ee81df2008-05-17 18:14:43 +00007382- Issue #1920: "while 0" statements were completely removed by the
7383 compiler, even in the presence of an "else" clause, which is
7384 supposed to be run when the condition is false. Now the compiler
7385 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007386
Guido van Rossumeead05f2008-01-24 18:21:02 +00007387- A few crashers fixed: weakref_in_del.py (issue #1377858);
7388 loosing_dict_ref.py (issue #1303614, test67.py);
7389 borrowed_ref_[34].py (not in tracker).
7390
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00007391- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00007392 suppressed while an extension is loaded by calling SetErrorMode in
7393 dynload_win.c. The error is still reported properly.
7394
Georg Brandl3ee81df2008-05-17 18:14:43 +00007395- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007396 several extension methods and modules do not work without unicode
7397 support.
7398
Georg Brandl26543b12008-01-21 18:36:51 +00007399- Issue #1882: when compiling code from a string, encoding cookies in the

7403
Georg Brandl6caad7d2008-01-26 14:19:22 +00007404- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007405 added.
7406
Christian Heimesc94e2b52008-01-14 04:13:37 +00007407- sys.float_info / PyFloat_GetInfo: The floating point information
7408 object was converted from a dict to a specialized structseq object.
7409
Georg Brandl3ee81df2008-05-17 18:14:43 +00007410- Patch #1816: Added sys.flags structseq. It exposes the status of
7411 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007412
Georg Brandl3ee81df2008-05-17 18:14:43 +00007413- Objects/structseq.c: Implemented new structseq representation. The
7414 patch makes structseqs (e.g. the return value of os.stat) more
7415 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007416
Georg Brandl3ee81df2008-05-17 18:14:43 +00007417- Patch #1700288: added a type attribute cache that caches method
7418 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00007419
Neal Norwitz3fc15b82008-01-10 05:42:58 +00007420- Bug #1776: __import__() no longer accepts filenames on any platform.

7426 envvar and sys.dont_write_bytecode attribute. All these can be set
7427 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007428
Georg Brandl3ee81df2008-05-17 18:14:43 +00007429- Improve some exception messages when Windows fails to load an
7430 extension module. Now we get for example '%1 is not a valid Win32
7431 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00007438- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00007439 and INF. float("nan"), float("inf") and float("-inf") now work on
7440 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00007441
Georg Brandl3ee81df2008-05-17 18:14:43 +00007442- Compiler now generates simpler and faster code for dictionary
7443 literals. The oparg for BUILD_MAP now indicates an estimated
7444 dictionary size. There is a new opcode, STORE_MAP, for adding
7445 entries to the dictionary.

7488
Georg Brandl21e99f42010-03-07 15:23:59 +00007489- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007490 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7491 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007492
Georg Brandl3ee81df2008-05-17 18:14:43 +00007493- Issue #1686386: Tuple's tp_repr did not take into account the
7494 possibility of having a self-referential tuple, which is possible
7495 from C code. Nor did object's tp_str consider that a type's tp_str
7496 could do something that could lead to an inifinite recursion.
7497 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7498 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007499
Georg Brandl3ee81df2008-05-17 18:14:43 +00007500- Issue #1164: It was possible to trigger deadlock when using the
7501 'print' statement to write to a file since the GIL was not released
7502 as needed. Now PyObject_Print() does the right thing along with
7503 various tp_print implementations of the built-in types and those in
7504 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007505
Georg Brandl3ee81df2008-05-17 18:14:43 +00007506- Issue #1147: Exceptions were directly allowing string exceptions in

Georg Brandl3ee81df2008-05-17 18:14:43 +00007514 PyObject_Call() never calling back out to Python code to trigger
7515 recursion depth updates/checks. Required the creation of a static
7516 RuntimeError instance in case normalizing an exception put the
7517 recursion check value past its limit. Fixes crashers

Georg Brandl5cb76c12007-03-21 09:00:39 +00007561- Patch #1682205: a TypeError while unpacking an iterable is no longer
7562 masked by a generic one with the message "unpack non-sequence".

Guido van Rossum143b5642007-03-23 04:58:42 +00007566- Bug #1683368: The object.__init__() and object.__new__() methods are
7567 now stricter in rejecting excess arguments. The only time when
7568 either allows excess arguments is when it is not overridden and the
7569 other one is. For backwards compatibility, when both are
7570 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007571 warning later). Also, type.__init__() insists on the same signature
7572 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00007574- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7575 object to complex using its __complex__() method before falling back
7576 to the __float__() method. Therefore, the functions in the cmath
7577 module now can operate on objects that define a __complex__()
7578 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00007596- Bug #1678647: write a newline after printing an exception in any
7597 case, even when converting the value to a string failed.
7598
Georg Brandl871f1bc2007-03-12 13:17:36 +00007599- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007600 its argument, if it exists. If not, it will work like before. This
7601 allows customizing the output of dir() in the presence of a
7602 __getattr__().

7612 raising a ValueError.

Georg Brandlaa2321b2007-03-07 00:40:28 +00007614- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007615 makes the filenames the warning module prints much more sensible
7616 when a PYTHONSTARTUP file is used.

7630 sq_ass_slice instead of the sq_slice slot.
7631
Georg Brandl3ee81df2008-05-17 18:14:43 +00007632- When printing an unraisable error, don't print exceptions. before

7685 embedded in the string to convert.
7686
Georg Brandl846f73a2006-10-08 07:11:54 +00007687- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00007735 generator expressions (x for x, in ... ) works again. Fixing this
7736 problem required changing the .pyc magic number. This means that
7737 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008540- The implementation of UnicodeError objects has been simplified
8541 (start and end attributes are now stored directly as Py_ssize_t
8542 members).

Georg Brandl3ee81df2008-05-17 18:14:43 +00008544- Issue #829951: In the smtplib module, SMTP.starttls() now complies
8545 with RFC 3207 and forgets any knowledge obtained from the server not
8546 obtained from the TLS negotiation itself. Patch contributed by Bill
8547 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00008548
Georg Brandl3ee81df2008-05-17 18:14:43 +00008549- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00008550 that the SMTP.starttls() caller no longer needs to call ehlo()
8551 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00008552 does not claim to support starttls. Adds the
8553 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
8554 Fenner.

8623 contents before adding elements from the iterable. This fix brings
8624 the behavior into line with that for list.__init__().
Raymond Hettingeradf9ffd2007-12-13 00:08:37 +00008625
Georg Brandl3ee81df2008-05-17 18:14:43 +00008626- Added wide char functions to msvcrt module: getwch, getwche, putwch

Georg Brandl3ee81df2008-05-17 18:14:43 +00008633- Marshal.dumps() now expects exact type matches for int, long, float,
8634 complex, tuple, list, dict, set, and frozenset. Formerly, it would
8635 silently miscode subclasses of those types. Now, it raises a
8636 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00008637

Georg Brandl3ee81df2008-05-17 18:14:43 +00008652 time so that opening a database previously created with the DB_DUP
8653 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8654 opens. Specifically: dictionary assignment to a DB object will
8655 replace all values for a given key when the database allows
8656 duplicate values. DB users should use DB.put(k, v) when they want
8657 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00008658

8664 characters with ASCII value less than 32. Also, it correctly quotes
8665 dots only if they occur on a single line, as opposed to the previous
8666 behavior of quoting dots if they are the second character of any
8667 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00008668

Georg Brandl3ee81df2008-05-17 18:14:43 +00009073- Removed the macfs module. It had been deprecated since Python 2.5.
9074 This lead to the deprecation of macostools.touched() as it relied
9075 solely on macfs and was a no-op under OS X.
