1402 32-bit-only installer Pythons on systems with Xcode 4 (currently
1403 OS X 10.8, 10.7, and optionally 10.6).
1404 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1405 * Since Xcode 4 removes ppc support, extension module builds now
1406 check for ppc compiler support and by default remove ppc and
1407 ppc64 archs when they are not available.
1408 * Extension module builds now revert to using system installed
1409 headers and libs (/usr and /System/Library) if the SDK used
1410 to build the interpreter is not installed or has moved.
1411 * Try to avoid building extension modules with deprecated
1412 and problematic Apple llvm-gcc compiler. If original compiler
1413 is not available, use clang instead by default.

Mark Dickinsona96b0d12011-09-24 09:01:16 +01001767 compiler optimizing the check away. Also fix similar overflow checks
1768 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
1769 bugs caused test failures with recent versions of Clang.

Florent Xiclunac2279652012-02-12 14:49:03 +01001837- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01001838 has left two versions of customize_compiler, the original in
1839 distutils.sysconfig and another copy in distutils.ccompiler, with some

Ned Deily0d0ea482012-02-10 12:59:06 +01001844- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1845 Distutils-based packages with C extension modules may fail because
1846 Apple has removed gcc-4.2, the version used to build python.org
1847 64-bit/32-bit Pythons. If the user does not explicitly override
1848 the default C compiler by setting the CC environment variable,
1849 Distutils will now attempt to compile extension modules with clang
1850 if gcc-4.2 is required but not found. Also as a convenience, if
1851 the user does explicitly set CC, substitute its value as the default
1852 compiler in the Distutils LDSHARED configuration variable for OS X.
1853 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1854 SDK, neither of which are available in Xcode 4. This change does not
1855 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07002105- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2106 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2107 interpreter process. This could cause failures in non-Distutils subprocesses
2108 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002109 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002110 deployment target only in the environment of each build subprocess. It is
2111 still possible to globally override the default by setting
2112 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2113 greater or equal to the default value, the value with which the interpreter
2114 was built.

2144 the ticker doesn't have to wind down to zero from the old starting point
2145 before the new interval takes effect. And if the user increases the
2146 interval, it makes sure the new limit takes effect right away rather have an
2147 early task switch before recognizing the new interval.

3126
Raymond Hettinger20397532010-09-12 02:11:45 +00003127- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
3128 This prevents user-created self-referencing ordered dictionaries from
3129 becoming permanently uncollectable GC garbage. The downside is that
3130 removing __del__ means that the internal doubly-linked list has to wait for
3131 GC collection rather than freeing memory immediately when the refcnt drops
3132 to zero.

3137
Antoine Pitrouc818ed42010-09-07 21:40:25 +00003138- Issue #9792: In case of connection failure, socket.create_connection()

3140 to fetch the original errno, or to filter timeout errors. Now the
3141 original error is re-raised.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00003590- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
3591 start byte and the continuation byte(s) are now considered invalid, instead
3592 of the number of bytes specified by the start byte.
3593 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
3594 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3595 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
3596 Previous versions returned a single u'\ufffd'.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00003604- Issue #8748: Fix two issues with comparisons between complex and integer
3605 objects. (1) The comparison could incorrectly return True in some cases
3606 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
3607 (2) The comparison raised an OverflowError for large integers, leading
3608 to unpredictable exceptions when combining integers and complex objects

3992 with a non-empty format string. This is an effort to future-proof user
3993 code. If a derived class does not currently implement __format__ but later

Georg Brandlba83f822010-03-14 09:50:54 +00004489 file position when calling `truncate()`. It would previously change the file
4490 position to the given argument, which goes against the tradition of

4494 class used to represent files stored inside an archive. The new
4495 implementation is significantly faster and can be wrapped in a
4496 ``io.BufferedReader`` object for more speedups. It also solves an issue
4497 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

4586-----------------
4587
Georg Brandlba83f822010-03-14 09:50:54 +00004588- The ``__complex__()`` method is now looked up on the class of instances to
4589 make it consistent with other special methods.

4593
Mark Dickinson1b34d252010-01-01 17:27:30 +00004594- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004595 DeprecationWarning when passed a float argument where an integer was expected.
4596 These functions and methods now raise TypeError instead. The majority of the
4597 effects of this change are in the extension modules, but some core functions
4598 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4599 and many unicode/str methods.

4613 of integers: the result of a/b is now correctly rounded for ints a and b (at
4614 least on IEEE 754 platforms), and in particular does not depend on the
4615 internal representation of a long.

4623
Georg Brandlba83f822010-03-14 09:50:54 +00004624 These executables now work properly with the arch(1) command: ``arch -ppc

4711 ``PyArg_ParseTupleAndKeywords()``, ``PyArg_VaParse()``,
4712 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept
4713 float arguments for integer format codes (other than 'L'): previously an
4714 attempt to pass a float resulted in a DeprecationWarning; now it gives a
4715 TypeError. For the 'L' format code (which previously had no warning) there is
4716 now a DeprecationWarning.

4765 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00004766
Georg Brandlba83f822010-03-14 09:50:54 +00004767- Remove switch from "%f" formatting to "%g" formatting for floats larger than
4768 1e50 in absolute value.

4772 significant digits instead.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00004780
Georg Brandlba83f822010-03-14 09:50:54 +00004781- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4782 decimal string that's guaranteed to round back to x under correct rounding
4783 (with round-half-to-even rounding mode). Previously it gave a string based on
4784 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4785 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4786 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004787
Georg Brandlba83f822010-03-14 09:50:54 +00004788- Issue #7117: On almost all platforms: float-to-string and string-to-float
4789 conversions within Python are now correctly rounded. Places these conversions
4790 occur include: str for floats and complex numbers; the float and complex
4791 constructors; old-style and new-style numeric formatting; serialization and
4792 deserialization of floats and complex numbers using marshal, pickle and json;
4793 parsing of float and imaginary literals in Python code; Decimal-to-float
4794 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004795
Georg Brandlba83f822010-03-14 09:50:54 +00004796 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4797 providing correctly-rounded strtod and dtoa C functions. This code is
4798 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4799 the C compiler. There may be a small number of platforms on which correct
4800 operation of this code cannot be guaranteed, so the code is not used: notably,
4801 this applies to platforms where the C double format is not IEEE 754 binary64,
4802 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4803 and Python's configure script is unable to determine how to change the FPU
4804 precision. On these platforms conversions use the platform strtod and dtoa,
4805 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004806
Georg Brandlba83f822010-03-14 09:50:54 +00004807- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4808 uses the correctly-rounded string <-> float conversions described above (when
4809 available), and so produces correctly rounded results that will display nicely
4810 under the float repr. There are two related small changes: (1) round now
4811 accepts any class with an ``__index__()`` method for its second argument (but
4812 no longer accepts floats for the second argument), and (2) an excessively
4813 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4814 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00004956
Georg Brandlba83f822010-03-14 09:50:54 +00004957 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
4958 (2) parsing of strings representing infinities and nans was locale aware; and
4959 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00004961- Issue #5920: For ``float.__format__()``, change the behavior with the empty
4962 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
4963 but with at least one decimal point and with a default precision
4964 of 12. Previously, the behavior the same but with a default precision of 6.
4965 This more closely matches ``str()``, and reduces surprises when adding
4966 alignment flags to the empty presentation type. This also affects the new
4967 complex.__format__ in the same way.
4968
4969- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

5220 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

Mark Dickinson5fd3af22009-07-07 15:08:28 +00006389
Georg Brandlba83f822010-03-14 09:50:54 +00006390- Issues #1530559, #1741130: Fix various struct.pack inconsistencies for the

Georg Brandlba83f822010-03-14 09:50:54 +00006394 - Packing a float now always gives a Deprecation Warning. Previously it
6395 only warned for 'I', 'L', '*B', '*H', '*I', '*L'.
Mark Dickinson463dc4b2009-07-05 10:01:24 +00006396
Georg Brandlba83f822010-03-14 09:50:54 +00006397 - If x is not an int, long or float, then packing x will always result in
6398 struct.error. Previously an x with an __int__ method could be packed by
6399 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
6400 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
6401 neither __int__ nor __long__, TypeError used to be raised (with a
6402 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
6403 struct.error in other cases.
Mark Dickinson463dc4b2009-07-05 10:01:24 +00006404
Georg Brandlba83f822010-03-14 09:50:54 +00006405 Note: as of Python 2.7 beta 1, the above is out of date. In 2.7 beta 1, any
6406 argument with an __int__ method can be packed, but use of this feature
6407 triggers a DeprecationWarning.

Antoine Pitrou59c44f32009-10-30 17:07:08 +00006455- Issue #7222: Make thread "reaping" more reliable so that reference
Georg Brandlba83f822010-03-14 09:50:54 +00006456 leak-chasing test runs give sensible results. The previous method of reaping
6457 threads could return successfully while some Thread objects were still
6458 referenced. This also introduces a new private function: ``thread._count()``.
Antoine Pitrou59c44f32009-10-30 17:07:08 +00006459
Georg Brandlba83f822010-03-14 09:50:54 +00006460- Issue #7151: Fixed regrtest -j so that output to stderr from a test no longer
6461 runs the risk of causing the worker thread to fail.
R. David Murray282396f2009-10-18 21:12:37 +00006462
Antoine Pitrou58d2f262009-10-10 20:52:11 +00006463- Issue #7055: test___all__ now greedily detects all modules which have an

Guilherme Polo7f146ab2009-06-21 17:22:50 +00006475- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
6476 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00006477 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
6478 the tests if DISPLAY is defined but can't be used.

Georg Brandlba83f822010-03-14 09:50:54 +00006483- Issue #5354: New test support function import_fresh_module() makes it easy to
6484 import both normal and optimised versions of modules. test_heapq and
6485 test_warnings have been adjusted to use it, tests for other modules with both
6486 C and Python implementations in the stdlib can be adjusted to use it over
6487 time.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00006598- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
6599
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006600- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6601 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6602 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6603 ``printf`` function, whereas PyString_FromFormat has an independent
6604 implementation and uses "%zd" on all platforms for size_t values.
6605 This makes a difference on win64, where ``printf`` needs "%Id" to display
6606 64bit values.
6607
Benjamin Peterson97179b02008-09-09 20:55:01 +00006608- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
6609 error.
6610
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00006611- Issue #3777: long() applied to a float object now always return a long
6612 object; previously an int would be returned for small values. the __long__
6613 method is allowed to return either an int or a long, but the behaviour of
6614 float objects should not change to respect backward compatibility.
6615
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00006616- Issue #3751: str.rpartition would perform a left-partition when called with
6617 a unicode argument.
6618
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00006619- Issue #3683: Fix compilation when --without-threads is given.

Vinay Sajip35e3b032008-09-01 14:33:59 +00006622 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00006623 was correctly parsed but parsing of subsequent arguments failed.
6624
Vinay Sajip35e3b032008-09-01 14:33:59 +00006625- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00006626 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
6627 mechanism. In the process, fix a bug where isinstance() and issubclass(),
6628 when given a tuple of classes as second argument, were looking up
6629 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6630 type object.
6631
Neal Norwitz18aa3882008-08-24 05:04:52 +00006632- Fix crashes on memory allocation failure found with failmalloc.

Brett Cannon1eaf0742008-09-02 01:25:16 +00006701 warnings.catch_warnings() along with some API cleanup. Expanding the tests
6702 for catch_warnings() also led to an improvement in the raising of a
6703 DeprecationWarning related to warnings.warn_explicit().
6704

6775-----------------
6776
Guido van Rossumf8402962008-08-20 15:01:50 +00006777- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6778 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6779 extensions do not automatically benefit from the class attribute
6780 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6781 to their tp_flags field if they care. This is a backwards
6782 compatibility feature; in 3.0, all types will use the cache by
6783 default.
6784
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006785- Keyword arguments can now follow starred arguments. (``f(a, *args,
6786 keyword=23)`` is now valid syntax.)
6787
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006788- ctypes function pointers that are COM methods have a boolean True
6789 value again.
6790
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006791- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6792 by denying s# to parse objects that have a releasebuffer procedure,
6793 and introducing s*.
6794
Georg Brandl1e13ea92008-08-11 09:07:59 +00006795- Issue #3537: Fix an assertion failure when an empty but presized dict
6796 object was stored in the freelist.
6797
Mark Dickinsonb6467572008-08-04 21:30:09 +00006798- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6799 ValueError consistently across platforms.
6800
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006801- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6802 (64bit Unix, for example), unichr() would truncate its argument and return
6803 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6804
Neal Norwitze7d8be82008-07-31 17:17:14 +00006805- Apply security patches from Apple.
6806
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006807- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6808 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6809
Antoine Pitrou92f82162008-07-25 22:22:08 +00006810- Issue #1819: function calls with several named parameters are now on
6811 average 35% faster (as measured by pybench).
6812
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006813- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6814 the python debugger steps into a class statement: the free variables (local
6815 variables defined in an outer scope) would be deleted from the outer scope.
6816
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006817- Issue #2620: Overflow checking when allocating or reallocating memory
6818 was not always being done properly in some python types and extension
6819 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6820 all been updated to perform better checks and places in the code that
6821 would previously leak memory on the error path when such an allocation
6822 failed have been fixed.

6826
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00006827- Issue #3612: Added some missing basic types in ctypes.wintypes.
6828
Benjamin Petersone977ad42008-08-20 01:42:01 +00006829- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6830 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6831
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006832- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6833 version reported by these tools does not necessarily follow the python
6834 version numbering scheme, so the module is less strict when parsing it.
6835
Nick Coghlanf70385a2008-08-18 12:42:46 +00006836- Issue #2235: Added Py3k warnings for types which will become unhashable
6837 under the stricter __hash__ inheritance rules in 3.0. Several types
6838 which did not meet the rules for hash invariants and were already
6839 unhashable in 3.0 have now been explicitly flagged as unhashable in
6840 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6841 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6842
Brett Cannon88f801d2008-08-18 00:46:22 +00006843- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

6970
Georg Brandl3e483f62008-07-16 22:57:41 +00006971- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6972 its methods now allow for items objects that can be converted to
6973 an integer using operator.index().
6974
Mark Dickinson64b7e502008-07-16 09:40:03 +00006975- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6976 produced a ValueError instead of giving the correct float.
6977
Eric Smitha5fa5a22008-07-16 00:11:49 +00006978- Issue #3083: Add alternate (#) formatting for bin, oct, hex output

Mark Dickinson7103aa42008-07-15 19:08:33 +00006981- Issue #3008: the float type has a new instance method 'float.hex'
6982 and a new class method 'float.fromhex' to convert floating-point
6983 numbers to and from hexadecimal strings, respectively.
6984
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006985- Issue #2235: __hash__ is once again inherited by default. To allow
6986 collections.Hashable to remain meaningful in the presence of the
6987 default hash implementation (object.__hash__), it is now possible
6988 to explicit block inheritance of hash by setting __hash__=None at
6989 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6990 level.

6993 the parent module cannot be found while performing an absolute import.
6994 This means that an incorrectly defined __package__ attribute will
6995 now only prevent relative imports in that module rather than causing
6996 all imports from that module to fail.
6997
Nick Coghlan14ff9942008-07-08 14:21:42 +00006998- Issue #2517: Allow unicode messages in Exceptions again by correctly

7008 another thread's dictionary.
7009
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007010- Issue #3004: Minor change to slice.indices(): the start and stop
7011 arguments are now treated identically, making the behaviour easier
7012 to describe and understand. For example, slice(None, -10,
7013 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7014 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7015 10, -1).

7058 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007059 wrong because the actual transmitted size could differ from the

Ronald Oussoren5640ce22008-06-05 12:58:24 +00007465- On MacOS X it is now possible to install the framework in 64-bit
7466 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00007467 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00007468
7469 This is controlled by the configure argument ``--with-universal-archs``:
7470
7471 - ``--with-universal-archs=all``: install 4-way universal
7472
7473 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
7474
7475 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
7476
7477 This option should be used in combination with ``--enable-universalsdk=``.
7478
7479 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 +00007528- Issue #1631171: Re-implement the 'warnings' module in C (the
7529 original Python code has been kept as backup). This will allow for
7530 using the 'warning's machinery in such places as the parser where
7531 use of pure Python code is not possible. Both the ``showarning()``
7532 and ``formatwarning()`` gain an optional 'line' argument which is
7533 not called by default for backwards-compatibility reasons. Setting
7534 ``warnings.showwarning()`` to an implementation that lacks support
7535 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007598- Issue #2550: The approach used by client/server code for obtaining
7599 ports to listen on in network-oriented tests has been refined in an
7600 effort to facilitate running multiple instances of the entire
7601 regression test suite in parallel without issue.
7602 test_support.bind_port() has been fixed such that it will always
7603 return a unique port -- which wasn't always the case with the
7604 previous implementation, especially if socket options had been set
7605 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7606 new implementation of bind_port() will actually raise an exception
7607 if it is passed an AF_INET/SOCK_STREAM socket with either the
7608 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7609 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7610 the socket it's been passed. This currently only applies to
7611 Windows. This option prevents any other sockets from binding to the
7612 host/port we've bound to, thus removing the possibility of the
7613 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7614 when a second SOCK_STREAM socket binds and accepts to a host/port
7615 that's already been bound by another socket. The optional preferred
7616 port parameter to bind_port() has been removed. Under no
7617 circumstances should tests be hard coding ports!
7618
7619 test_support.find_unused_port() has also been introduced, which will
7620 pass a temporary socket object to bind_port() in order to obtain an
7621 unused port. The temporary socket object is then closed and
7622 deleted, and the port is returned. This method should only be used
7623 for obtaining an unused port in order to pass to an external program
7624 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7625 a parameter to a server-oriented class that doesn't give you direct
7626 access to the underlying socket used.
7627
7628 Finally, test_support.HOST has been introduced, which should be used
7629 for the host argument of any relevant socket calls (i.e. bind and
7630 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007631
7632 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007633 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007634 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7635 test_asynchat and test_socket_ssl.
7636
Georg Brandl3ee81df2008-05-17 18:14:43 +00007637 It is now possible for multiple instances of the regression test
7638 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00007692- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00007693 \Uxxxxxxxx did not accept values outside the Basic Multilingual
7694 Plane. This affected raw unicode literals and the
7695 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
7696 this case, like normal unicode literals and the 'unicode-escape'
7697 codec.

Eric Smitha73fbe72008-02-23 03:09:44 +00007917- Added the future_builtins module, which contains hex() and oct().
7918 These are the PEP 3127 version of these functions, designed to be
7919 compatible with the hex() and oct() builtins from Python 3.0. They
7920 differ slightly in their output formats from the existing, unchanged
7921 Python 2.6 builtins. The expected usage of the future_builtins
7922 module is:
7923 from future_builtins import hex, oct
7924
Eric Smith7ef40bf2008-02-20 23:34:22 +00007925- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7926 exponents for exponents with absolute value < 100. Follows C99
7927 standard. This is a change on Windows, which would use 3 digits.
7928 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7929 so that any alterations it does to the resulting string will be
7930 available in stringlib/formatter.h (for float.__format__).
7931
Eric Smith5a3c1352008-02-19 13:21:56 +00007932- Implemented PEP 3101, Advanced String Formatting. This adds a new
7933 builtin format(); a format() method for str and unicode; a
7934 __format__() method to object, str, unicode, int, long, float, and
7935 datetime; the class string.Formatter; and the C API
7936 PyObject_Format().
7937
Georg Brandl3ee81df2008-05-17 18:14:43 +00007938- Fixed several potential crashes, all caused by specially crafted
7939 __del__ methods exploiting objects in temporarily inconsistent
7940 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00007941
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007942- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00007943 prevent a possible crash: an Abstract Base Class would try to access
7944 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00007945

Georg Brandl3ee81df2008-05-17 18:14:43 +00007983- Patch #1473257: generator objects gain a gi_code attribute. This is
7984 the same object as the func_code attribute of the function that
7985 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007986
Georg Brandl3ee81df2008-05-17 18:14:43 +00007987- Issue #1920: "while 0" statements were completely removed by the
7988 compiler, even in the presence of an "else" clause, which is
7989 supposed to be run when the condition is false. Now the compiler
7990 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007991
Guido van Rossumeead05f2008-01-24 18:21:02 +00007992- A few crashers fixed: weakref_in_del.py (issue #1377858);

7999
Georg Brandl3ee81df2008-05-17 18:14:43 +00008000- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00008001 several extension methods and modules do not work without unicode
8002 support.
8003

8008
Georg Brandl6caad7d2008-01-26 14:19:22 +00008009- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008010 added.
8011
Christian Heimesc94e2b52008-01-14 04:13:37 +00008012- sys.float_info / PyFloat_GetInfo: The floating point information
8013 object was converted from a dict to a specialized structseq object.
8014
Georg Brandl3ee81df2008-05-17 18:14:43 +00008015- Patch #1816: Added sys.flags structseq. It exposes the status of
8016 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008017
Georg Brandl3ee81df2008-05-17 18:14:43 +00008018- Objects/structseq.c: Implemented new structseq representation. The
8019 patch makes structseqs (e.g. the return value of os.stat) more
8020 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00008021
Georg Brandl3ee81df2008-05-17 18:14:43 +00008022- Patch #1700288: added a type attribute cache that caches method
8023 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00008024
Neal Norwitz3fc15b82008-01-10 05:42:58 +00008025- Bug #1776: __import__() no longer accepts filenames on any platform.

8031 envvar and sys.dont_write_bytecode attribute. All these can be set
8032 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00008033
Georg Brandl3ee81df2008-05-17 18:14:43 +00008034- Improve some exception messages when Windows fails to load an
8035 extension module. Now we get for example '%1 is not a valid Win32
8036 application' instead of 'error code 193'.

8093
Georg Brandl21e99f42010-03-07 15:23:59 +00008094- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008095 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8096 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008097
Georg Brandl3ee81df2008-05-17 18:14:43 +00008098- Issue #1686386: Tuple's tp_repr did not take into account the
8099 possibility of having a self-referential tuple, which is possible
8100 from C code. Nor did object's tp_str consider that a type's tp_str
8101 could do something that could lead to an inifinite recursion.
8102 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8103 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008104

8106 'print' statement to write to a file since the GIL was not released
8107 as needed. Now PyObject_Print() does the right thing along with
8108 various tp_print implementations of the built-in types and those in
8109 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00008110

Georg Brandl3ee81df2008-05-17 18:14:43 +00008119 PyObject_Call() never calling back out to Python code to trigger
8120 recursion depth updates/checks. Required the creation of a static
8121 RuntimeError instance in case normalizing an exception put the
8122 recursion check value past its limit. Fixes crashers

Guido van Rossum143b5642007-03-23 04:58:42 +00008171- Bug #1683368: The object.__init__() and object.__new__() methods are
8172 now stricter in rejecting excess arguments. The only time when
8173 either allows excess arguments is when it is not overridden and the
8174 other one is. For backwards compatibility, when both are
8175 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008176 warning later). Also, type.__init__() insists on the same signature
8177 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00008179- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8180 object to complex using its __complex__() method before falling back
8181 to the __float__() method. Therefore, the functions in the cmath
8182 module now can operate on objects that define a __complex__()
8183 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00008201- Bug #1678647: write a newline after printing an exception in any
8202 case, even when converting the value to a string failed.
8203
Georg Brandl871f1bc2007-03-12 13:17:36 +00008204- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008205 its argument, if it exists. If not, it will work like before. This
8206 allows customizing the output of dir() in the presence of a
8207 __getattr__().

8217 raising a ValueError.

Georg Brandlaa2321b2007-03-07 00:40:28 +00008219- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008220 makes the filenames the warning module prints much more sensible
8221 when a PYTHONSTARTUP file is used.

8235 sq_ass_slice instead of the sq_slice slot.
8236
Georg Brandl3ee81df2008-05-17 18:14:43 +00008237- When printing an unraisable error, don't print exceptions. before

Neal Norwitzcbeb6872006-10-14 21:33:38 +00008288
Georg Brandl2c1375c2006-10-12 11:27:59 +00008289- Bug #1545497: when given an explicit base, int() did ignore NULs
8290 embedded in the string to convert.
8291
Georg Brandl846f73a2006-10-08 07:11:54 +00008292- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl4e933132006-09-06 20:05:58 +00008322- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.
8323 Also make sure that every exception class has __module__ set to
8324 'exceptions'.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008340 generator expressions (x for x, in ... ) works again. Fixing this
8341 problem required changing the .pyc magic number. This means that
8342 .pyc files generated before 2.5c2 will be regenerated.

9144 obtained from the TLS negotiation itself. Patch contributed by Bill
9145 Fenner.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009147- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00009148 that the SMTP.starttls() caller no longer needs to call ehlo()
9149 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00009150 does not claim to support starttls. Adds the
9151 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

9232 complex, tuple, list, dict, set, and frozenset. Formerly, it would
9233 silently miscode subclasses of those types. Now, it raises a
9234 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00009235

Georg Brandl3ee81df2008-05-17 18:14:43 +00009250 time so that opening a database previously created with the DB_DUP
9251 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9252 opens. Specifically: dictionary assignment to a DB object will
9253 replace all values for a given key when the database allows
9254 duplicate values. DB users should use DB.put(k, v) when they want
9255 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009256

9262 characters with ASCII value less than 32. Also, it correctly quotes
9263 dots only if they occur on a single line, as opposed to the previous
9264 behavior of quoting dots if they are the second character of any
9265 line.
