Mark Dickinsondbbed042011-09-19 16:38:08 +0100607- Issue #12973: Fix overflow checks that invoked undefined behaviour in
608 int.__pow__. These overflow checks were causing int.__pow__ to produce
609 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +0100610 compiler optimizing the check away. Also fix similar overflow checks
611 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
612 bugs caused test failures with recent versions of Clang.

Florent Xiclunac2279652012-02-12 14:49:03 +0100680- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +0100681 has left two versions of customize_compiler, the original in
682 distutils.sysconfig and another copy in distutils.ccompiler, with some

Ned Deily0d0ea482012-02-10 12:59:06 +0100687- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
688 Distutils-based packages with C extension modules may fail because
689 Apple has removed gcc-4.2, the version used to build python.org
690 64-bit/32-bit Pythons. If the user does not explicitly override
691 the default C compiler by setting the CC environment variable,
692 Distutils will now attempt to compile extension modules with clang
693 if gcc-4.2 is required but not found. Also as a convenience, if
694 the user does explicitly set CC, substitute its value as the default
695 compiler in the Distutils LDSHARED configuration variable for OS X.
696 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
697 SDK, neither of which are available in Xcode 4. This change does not
698 attempt to override settings to support their use with Xcode 4.)

970
Ned Deily87e82bb2011-06-28 19:52:59 -0700971- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
972 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
973 interpreter process. This could cause failures in non-Distutils subprocesses
974 and was unreliable since tests or user programs could modify the interpreter
975 environment after Distutils set it. Instead, have Distutils set the the
976 deployment target only in the environment of each build subprocess. It is
977 still possible to globally override the default by setting
978 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
979 greater or equal to the default value, the value with which the interpreter
980 was built.

1007
Barry Warsawc5643282011-07-19 17:06:30 -04001008- sys.setcheckinterval() now updates the current ticker count as well as
1009 updating the check interval, so if the user decreases the check interval,
1010 the ticker doesn't have to wind down to zero from the old starting point
1011 before the new interval takes effect. And if the user increases the
1012 interval, it makes sure the new limit takes effect right away rather have an
1013 early task switch before recognizing the new interval.

1963
Raymond Hettinger20397532010-09-12 02:11:45 +00001964- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
1965 This prevents user-created self-referencing ordered dictionaries from
1966 becoming permanently uncollectable GC garbage. The downside is that
1967 removing __del__ means that the internal doubly-linked list has to wait for
1968 GC collection rather than freeing memory immediately when the refcnt drops
1969 to zero.

1974
Antoine Pitrouc818ed42010-09-07 21:40:25 +00001975- Issue #9792: In case of connection failure, socket.create_connection()

1977 to fetch the original errno, or to filter timeout errors. Now the
1978 original error is re-raised.

2427
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00002428- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
2429 start byte and the continuation byte(s) are now considered invalid, instead
2430 of the number of bytes specified by the start byte.
2431 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
2432 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
2433 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
2434 Previous versions returned a single u'\ufffd'.

2438 arises from the "Overriding __eq__ blocks inheritance ..." warning
2439 when turned into an exception: in this case the exception simply
2440 gets ignored.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00002442- Issue #8748: Fix two issues with comparisons between complex and integer
2443 objects. (1) The comparison could incorrectly return True in some cases
2444 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
2445 (2) The comparison raised an OverflowError for large integers, leading
2446 to unpredictable exceptions when combining integers and complex objects
2447 in sets or dicts.
2448
Mark Dickinson81336372010-05-30 12:12:25 +00002449- Issue #5211: Implicit coercion for the complex type is now completely
2450 removed. (Coercion for arithmetic operations was already removed in 2.7

Victor Stinnerc49dfcc2010-05-25 22:30:32 +00002453- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding

Georg Brandlba83f822010-03-14 09:50:54 +00003327 file position when calling `truncate()`. It would previously change the file
3328 position to the given argument, which goes against the tradition of

3332 class used to represent files stored inside an archive. The new
3333 implementation is significantly faster and can be wrapped in a
3334 ``io.BufferedReader`` object for more speedups. It also solves an issue
3335 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

3424-----------------
3425
Georg Brandlba83f822010-03-14 09:50:54 +00003426- The ``__complex__()`` method is now looked up on the class of instances to
3427 make it consistent with other special methods.

3431
Mark Dickinson1b34d252010-01-01 17:27:30 +00003432- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00003433 DeprecationWarning when passed a float argument where an integer was expected.
3434 These functions and methods now raise TypeError instead. The majority of the
3435 effects of this change are in the extension modules, but some core functions
3436 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3437 and many unicode/str methods.

3451 of integers: the result of a/b is now correctly rounded for ints a and b (at
3452 least on IEEE 754 platforms), and in particular does not depend on the
3453 internal representation of a long.

3461
Georg Brandlba83f822010-03-14 09:50:54 +00003462 These executables now work properly with the arch(1) command: ``arch -ppc

3550 ``PyArg_ParseTupleAndKeywords()``, ``PyArg_VaParse()``,
3551 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept
3552 float arguments for integer format codes (other than 'L'): previously an
3553 attempt to pass a float resulted in a DeprecationWarning; now it gives a
3554 TypeError. For the 'L' format code (which previously had no warning) there is
3555 now a DeprecationWarning.

3604 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00003605

3607 1e50 in absolute value.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00003619
Georg Brandlba83f822010-03-14 09:50:54 +00003620- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3621 decimal string that's guaranteed to round back to x under correct rounding
3622 (with round-half-to-even rounding mode). Previously it gave a string based on
3623 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3624 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3625 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003626
Georg Brandlba83f822010-03-14 09:50:54 +00003627- Issue #7117: On almost all platforms: float-to-string and string-to-float
3628 conversions within Python are now correctly rounded. Places these conversions
3629 occur include: str for floats and complex numbers; the float and complex
3630 constructors; old-style and new-style numeric formatting; serialization and
3631 deserialization of floats and complex numbers using marshal, pickle and json;
3632 parsing of float and imaginary literals in Python code; Decimal-to-float
3633 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003634
Georg Brandlba83f822010-03-14 09:50:54 +00003635 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3636 providing correctly-rounded strtod and dtoa C functions. This code is
3637 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3638 the C compiler. There may be a small number of platforms on which correct
3639 operation of this code cannot be guaranteed, so the code is not used: notably,
3640 this applies to platforms where the C double format is not IEEE 754 binary64,
3641 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3642 and Python's configure script is unable to determine how to change the FPU
3643 precision. On these platforms conversions use the platform strtod and dtoa,
3644 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003645
Georg Brandlba83f822010-03-14 09:50:54 +00003646- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3647 uses the correctly-rounded string <-> float conversions described above (when
3648 available), and so produces correctly rounded results that will display nicely
3649 under the float repr. There are two related small changes: (1) round now
3650 accepts any class with an ``__index__()`` method for its second argument (but
3651 no longer accepts floats for the second argument), and (2) an excessively
3652 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3653 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00003783- Issue #5829: complex("1e500") no longer raises OverflowError. This makes it
3784 consistent with float("1e500") and interpretation of real and imaginary
3785 literals.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00003794- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
Mark Dickinsonb1d45852009-05-11 15:33:08 +00003795
Georg Brandlba83f822010-03-14 09:50:54 +00003796 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
3797 (2) parsing of strings representing infinities and nans was locale aware; and
3798 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').
Eric Smitha985a3a2009-05-05 18:26:08 +00003799
Georg Brandlba83f822010-03-14 09:50:54 +00003800- Issue #5920: For ``float.__format__()``, change the behavior with the empty
3801 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
3802 but with at least one decimal point and with a default precision
3803 of 12. Previously, the behavior the same but with a default precision of 6.
3804 This more closely matches ``str()``, and reduces surprises when adding
3805 alignment flags to the empty presentation type. This also affects the new
3806 complex.__format__ in the same way.
3807
3808- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
3809 classtype's, even if it was None. property now inserts the __doc__ into the
3810 subclass instance __dict__.

Antoine Pitrouf8387af2009-03-23 18:41:45 +00003870- Issue #4688: Add a heuristic so that tuples and dicts containing only
Georg Brandlba83f822010-03-14 09:50:54 +00003871 untrackable objects are not tracked by the garbage collector. This can reduce
3872 the size of collections and therefore the garbage collection overhead on

3880 internal representation of integers, for performance reasons. Base 2**30 is
3881 enabled by default on 64-bit machines. Add --enable-big-digits option to
3882 configure, which overrides the default. Add sys.long_info structseq to
3883 provide information about the internal format.

Georg Brandlba83f822010-03-14 09:50:54 +00004030- On windows, ``os.chdir()`` given unicode was not working if

4032 this code path is really executed because I cannot move to such directory on
4033 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00004035- Issue #4069: When ``set.remove(element)`` is used with a set element, the
4036 element is temporarily replaced with an equivalent frozenset. But the
4037 eventual KeyError would always report the empty ``frozenset()`` as the missing
4038 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00004058- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
4059 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
4060 step. This avoids problems with counting UTF-8 bytes that ignores the effect
4061 of using the replace error handler in PyUnicode_DecodeUTF8().
4062
Walter Dörwald726ba8e2009-05-06 14:32:35 +00004063- Issue #3739: The unicode-internal encoder now reports the number of characters

4065
Georg Brandlba83f822010-03-14 09:50:54 +00004066- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
4067 allocator will be automatically disabled when running under Valgrind. This
4068 gives improved memory leak detection when running under Valgrind, while taking
4069 advantage of pymalloc at other times.

Georg Brandlba83f822010-03-14 09:50:54 +00005233 - If x is not an int, long or float, then packing x will always result in
5234 struct.error. Previously an x with an __int__ method could be packed by
5235 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
5236 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
5237 neither __int__ nor __long__, TypeError used to be raised (with a
5238 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
5239 struct.error in other cases.

5242 argument with an __int__ method can be packed, but use of this feature
5243 triggers a DeprecationWarning.

Georg Brandlba83f822010-03-14 09:50:54 +00005292 leak-chasing test runs give sensible results. The previous method of reaping
5293 threads could return successfully while some Thread objects were still

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00005434- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
5435
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005436- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5437 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5438 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5439 ``printf`` function, whereas PyString_FromFormat has an independent
5440 implementation and uses "%zd" on all platforms for size_t values.
5441 This makes a difference on win64, where ``printf`` needs "%Id" to display
5442 64bit values.
5443
Benjamin Peterson97179b02008-09-09 20:55:01 +00005444- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
5445 error.
5446
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00005447- Issue #3777: long() applied to a float object now always return a long
5448 object; previously an int would be returned for small values. the __long__
5449 method is allowed to return either an int or a long, but the behaviour of
5450 float objects should not change to respect backward compatibility.
5451
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00005452- Issue #3751: str.rpartition would perform a left-partition when called with
5453 a unicode argument.
5454
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00005455- Issue #3683: Fix compilation when --without-threads is given.

Vinay Sajip35e3b032008-09-01 14:33:59 +00005458 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005459 was correctly parsed but parsing of subsequent arguments failed.
5460
Vinay Sajip35e3b032008-09-01 14:33:59 +00005461- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005462 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5463 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5464 when given a tuple of classes as second argument, were looking up
5465 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5466 type object.
5467
Neal Norwitz18aa3882008-08-24 05:04:52 +00005468- Fix crashes on memory allocation failure found with failmalloc.

5477 function 'stringlib_contains_obj'.

Brett Cannon1eaf0742008-09-02 01:25:16 +00005537 warnings.catch_warnings() along with some API cleanup. Expanding the tests
5538 for catch_warnings() also led to an improvement in the raising of a
5539 DeprecationWarning related to warnings.warn_explicit().
5540

5611-----------------
5612
Guido van Rossumf8402962008-08-20 15:01:50 +00005613- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5614 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5615 extensions do not automatically benefit from the class attribute
5616 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5617 to their tp_flags field if they care. This is a backwards
5618 compatibility feature; in 3.0, all types will use the cache by
5619 default.
5620
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005621- Keyword arguments can now follow starred arguments. (``f(a, *args,
5622 keyword=23)`` is now valid syntax.)
5623
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005624- ctypes function pointers that are COM methods have a boolean True
5625 value again.
5626
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005627- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5628 by denying s# to parse objects that have a releasebuffer procedure,
5629 and introducing s*.
5630
Georg Brandl1e13ea92008-08-11 09:07:59 +00005631- Issue #3537: Fix an assertion failure when an empty but presized dict
5632 object was stored in the freelist.
5633
Mark Dickinsonb6467572008-08-04 21:30:09 +00005634- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5635 ValueError consistently across platforms.
5636
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005637- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5638 (64bit Unix, for example), unichr() would truncate its argument and return
5639 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5640
Neal Norwitze7d8be82008-07-31 17:17:14 +00005641- Apply security patches from Apple.
5642
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005643- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5644 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5645
Antoine Pitrou92f82162008-07-25 22:22:08 +00005646- Issue #1819: function calls with several named parameters are now on
5647 average 35% faster (as measured by pybench).
5648
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005649- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5650 the python debugger steps into a class statement: the free variables (local
5651 variables defined in an outer scope) would be deleted from the outer scope.
5652
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005653- Issue #2620: Overflow checking when allocating or reallocating memory
5654 was not always being done properly in some python types and extension
5655 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5656 all been updated to perform better checks and places in the code that
5657 would previously leak memory on the error path when such an allocation
5658 failed have been fixed.

5662
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00005663- Issue #3612: Added some missing basic types in ctypes.wintypes.
5664
Benjamin Petersone977ad42008-08-20 01:42:01 +00005665- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5666 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5667
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005668- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5669 version reported by these tools does not necessarily follow the python
5670 version numbering scheme, so the module is less strict when parsing it.
5671
Nick Coghlanf70385a2008-08-18 12:42:46 +00005672- Issue #2235: Added Py3k warnings for types which will become unhashable
5673 under the stricter __hash__ inheritance rules in 3.0. Several types
5674 which did not meet the rules for hash invariants and were already
5675 unhashable in 3.0 have now been explicitly flagged as unhashable in
5676 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5677 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5678
Brett Cannon88f801d2008-08-18 00:46:22 +00005679- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

5792
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00005793- Issue #643841: The language reference now provides more detailed

5805-----------------
5806
Georg Brandl3e483f62008-07-16 22:57:41 +00005807- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5808 its methods now allow for items objects that can be converted to
5809 an integer using operator.index().
5810
Mark Dickinson64b7e502008-07-16 09:40:03 +00005811- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5812 produced a ValueError instead of giving the correct float.
5813
Eric Smitha5fa5a22008-07-16 00:11:49 +00005814- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5815 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5816
Mark Dickinson7103aa42008-07-15 19:08:33 +00005817- Issue #3008: the float type has a new instance method 'float.hex'
5818 and a new class method 'float.fromhex' to convert floating-point
5819 numbers to and from hexadecimal strings, respectively.
5820
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005821- Issue #2235: __hash__ is once again inherited by default. To allow
5822 collections.Hashable to remain meaningful in the presence of the
5823 default hash implementation (object.__hash__), it is now possible
5824 to explicit block inheritance of hash by setting __hash__=None at
5825 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5826 level.
5827
Nick Coghlanb028f502008-07-13 14:52:36 +00005828- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5829 the parent module cannot be found while performing an absolute import.
5830 This means that an incorrectly defined __package__ attribute will
5831 now only prevent relative imports in that module rather than causing
5832 all imports from that module to fail.
5833
Nick Coghlan14ff9942008-07-08 14:21:42 +00005834- Issue #2517: Allow unicode messages in Exceptions again by correctly

5844 another thread's dictionary.
5845
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005846- Issue #3004: Minor change to slice.indices(): the start and stop
5847 arguments are now treated identically, making the behaviour easier
5848 to describe and understand. For example, slice(None, -10,
5849 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5850 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5851 10, -1).
5852
Georg Brandl278fc502008-07-19 12:46:12 +00005853- Issue #3219: Calling a function with repeated keyword arguments,
5854 f(a=2, a=23), would not cause a syntax error. This was a regression
5855 from 2.4 caused by the switch to the new compiler.

5894 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005895 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005896 content-length. The problem had been corrected in the 2.4 branch, but never

6302
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006303- On MacOS X it is now possible to install the framework in 64-bit
6304 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00006305 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006306
6307 This is controlled by the configure argument ``--with-universal-archs``:
6308
6309 - ``--with-universal-archs=all``: install 4-way universal
6310
6311 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6312
6313 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6314
6315 This option should be used in combination with ``--enable-universalsdk=``.
6316
6317 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 +00006367- Issue #1631171: Re-implement the 'warnings' module in C (the
6368 original Python code has been kept as backup). This will allow for
6369 using the 'warning's machinery in such places as the parser where
6370 use of pure Python code is not possible. Both the ``showarning()``
6371 and ``formatwarning()`` gain an optional 'line' argument which is
6372 not called by default for backwards-compatibility reasons. Setting
6373 ``warnings.showwarning()`` to an implementation that lacks support
6374 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006437- Issue #2550: The approach used by client/server code for obtaining
6438 ports to listen on in network-oriented tests has been refined in an
6439 effort to facilitate running multiple instances of the entire
6440 regression test suite in parallel without issue.
6441 test_support.bind_port() has been fixed such that it will always
6442 return a unique port -- which wasn't always the case with the
6443 previous implementation, especially if socket options had been set
6444 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6445 new implementation of bind_port() will actually raise an exception
6446 if it is passed an AF_INET/SOCK_STREAM socket with either the
6447 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6448 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6449 the socket it's been passed. This currently only applies to
6450 Windows. This option prevents any other sockets from binding to the
6451 host/port we've bound to, thus removing the possibility of the
6452 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6453 when a second SOCK_STREAM socket binds and accepts to a host/port
6454 that's already been bound by another socket. The optional preferred
6455 port parameter to bind_port() has been removed. Under no
6456 circumstances should tests be hard coding ports!
6457
6458 test_support.find_unused_port() has also been introduced, which will
6459 pass a temporary socket object to bind_port() in order to obtain an
6460 unused port. The temporary socket object is then closed and
6461 deleted, and the port is returned. This method should only be used
6462 for obtaining an unused port in order to pass to an external program
6463 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6464 a parameter to a server-oriented class that doesn't give you direct
6465 access to the underlying socket used.
6466
6467 Finally, test_support.HOST has been introduced, which should be used
6468 for the host argument of any relevant socket calls (i.e. bind and
6469 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006470
6471 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006472 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006473 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6474 test_asynchat and test_socket_ssl.
6475
Georg Brandl3ee81df2008-05-17 18:14:43 +00006476 It is now possible for multiple instances of the regression test
6477 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00006531- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00006532 \Uxxxxxxxx did not accept values outside the Basic Multilingual
6533 Plane. This affected raw unicode literals and the
6534 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
6535 this case, like normal unicode literals and the 'unicode-escape'
6536 codec.

Eric Smitha73fbe72008-02-23 03:09:44 +00006756- Added the future_builtins module, which contains hex() and oct().
6757 These are the PEP 3127 version of these functions, designed to be
6758 compatible with the hex() and oct() builtins from Python 3.0. They
6759 differ slightly in their output formats from the existing, unchanged
6760 Python 2.6 builtins. The expected usage of the future_builtins
6761 module is:
6762 from future_builtins import hex, oct
6763
Eric Smith7ef40bf2008-02-20 23:34:22 +00006764- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6765 exponents for exponents with absolute value < 100. Follows C99
6766 standard. This is a change on Windows, which would use 3 digits.
6767 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6768 so that any alterations it does to the resulting string will be
6769 available in stringlib/formatter.h (for float.__format__).
6770
Eric Smith5a3c1352008-02-19 13:21:56 +00006771- Implemented PEP 3101, Advanced String Formatting. This adds a new
6772 builtin format(); a format() method for str and unicode; a
6773 __format__() method to object, str, unicode, int, long, float, and
6774 datetime; the class string.Formatter; and the C API
6775 PyObject_Format().
6776
Georg Brandl3ee81df2008-05-17 18:14:43 +00006777- Fixed several potential crashes, all caused by specially crafted
6778 __del__ methods exploiting objects in temporarily inconsistent
6779 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006780
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006781- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006782 prevent a possible crash: an Abstract Base Class would try to access
6783 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00006784

Georg Brandl3ee81df2008-05-17 18:14:43 +00006788- Clear all free lists during a gc.collect() of the highest generation
6789 in order to allow pymalloc to free more arenas. Python may give back
6790 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006791
Georg Brandl3ee81df2008-05-17 18:14:43 +00006792- Issue #2045: Fix an infinite recursion triggered when printing a
6793 subclass of collections.defaultdict, if its default_factory is set
6794 to a bound method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006822- Patch #1473257: generator objects gain a gi_code attribute. This is
6823 the same object as the func_code attribute of the function that
6824 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006825
Georg Brandl3ee81df2008-05-17 18:14:43 +00006826- Issue #1920: "while 0" statements were completely removed by the
6827 compiler, even in the presence of an "else" clause, which is
6828 supposed to be run when the condition is false. Now the compiler
6829 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006830
Guido van Rossumeead05f2008-01-24 18:21:02 +00006831- A few crashers fixed: weakref_in_del.py (issue #1377858);

6838
Georg Brandl3ee81df2008-05-17 18:14:43 +00006839- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006840 several extension methods and modules do not work without unicode
6841 support.
6842
Georg Brandl26543b12008-01-21 18:36:51 +00006843- Issue #1882: when compiling code from a string, encoding cookies in the

6847
Georg Brandl6caad7d2008-01-26 14:19:22 +00006848- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006849 added.
6850
Christian Heimesc94e2b52008-01-14 04:13:37 +00006851- sys.float_info / PyFloat_GetInfo: The floating point information
6852 object was converted from a dict to a specialized structseq object.
6853
Georg Brandl3ee81df2008-05-17 18:14:43 +00006854- Patch #1816: Added sys.flags structseq. It exposes the status of
6855 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006856
Georg Brandl3ee81df2008-05-17 18:14:43 +00006857- Objects/structseq.c: Implemented new structseq representation. The
6858 patch makes structseqs (e.g. the return value of os.stat) more
6859 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006860
Georg Brandl3ee81df2008-05-17 18:14:43 +00006861- Patch #1700288: added a type attribute cache that caches method
6862 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00006863
Neal Norwitz3fc15b82008-01-10 05:42:58 +00006864- Bug #1776: __import__() no longer accepts filenames on any platform.

6870 envvar and sys.dont_write_bytecode attribute. All these can be set
6871 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006872
Georg Brandl3ee81df2008-05-17 18:14:43 +00006873- Improve some exception messages when Windows fails to load an
6874 extension module. Now we get for example '%1 is not a valid Win32
6875 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00006882- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006883 and INF. float("nan"), float("inf") and float("-inf") now work on
6884 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006885
Georg Brandl3ee81df2008-05-17 18:14:43 +00006886- Compiler now generates simpler and faster code for dictionary

6932
Georg Brandl21e99f42010-03-07 15:23:59 +00006933- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006934 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6935 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006936
Georg Brandl3ee81df2008-05-17 18:14:43 +00006937- Issue #1686386: Tuple's tp_repr did not take into account the
6938 possibility of having a self-referential tuple, which is possible
6939 from C code. Nor did object's tp_str consider that a type's tp_str
6940 could do something that could lead to an inifinite recursion.
6941 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6942 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006943
Georg Brandl3ee81df2008-05-17 18:14:43 +00006944- Issue #1164: It was possible to trigger deadlock when using the
6945 'print' statement to write to a file since the GIL was not released
6946 as needed. Now PyObject_Print() does the right thing along with
6947 various tp_print implementations of the built-in types and those in
6948 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006949

Georg Brandl3ee81df2008-05-17 18:14:43 +00006958 PyObject_Call() never calling back out to Python code to trigger
6959 recursion depth updates/checks. Required the creation of a static
6960 RuntimeError instance in case normalizing an exception put the
6961 recursion check value past its limit. Fixes crashers
6962 infinite_rec_(1|2|4|5).py.

Guido van Rossum143b5642007-03-23 04:58:42 +00007010- Bug #1683368: The object.__init__() and object.__new__() methods are
7011 now stricter in rejecting excess arguments. The only time when
7012 either allows excess arguments is when it is not overridden and the
7013 other one is. For backwards compatibility, when both are
7014 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007015 warning later). Also, type.__init__() insists on the same signature
7016 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00007018- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7019 object to complex using its __complex__() method before falling back
7020 to the __float__() method. Therefore, the functions in the cmath
7021 module now can operate on objects that define a __complex__()
7022 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00007040- Bug #1678647: write a newline after printing an exception in any
7041 case, even when converting the value to a string failed.
7042
Georg Brandl871f1bc2007-03-12 13:17:36 +00007043- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007044 its argument, if it exists. If not, it will work like before. This
7045 allows customizing the output of dir() in the presence of a
7046 __getattr__().

7056 raising a ValueError.

Georg Brandlaa2321b2007-03-07 00:40:28 +00007058- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007059 makes the filenames the warning module prints much more sensible
7060 when a PYTHONSTARTUP file is used.

7074 sq_ass_slice instead of the sq_slice slot.
7075
Georg Brandl3ee81df2008-05-17 18:14:43 +00007076- When printing an unraisable error, don't print exceptions. before

Georg Brandl2c1375c2006-10-12 11:27:59 +00007128- Bug #1545497: when given an explicit base, int() did ignore NULs
7129 embedded in the string to convert.
7130
Georg Brandl846f73a2006-10-08 07:11:54 +00007131- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00007179 generator expressions (x for x, in ... ) works again. Fixing this
7180 problem required changing the .pyc magic number. This means that
7181 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007984- The implementation of UnicodeError objects has been simplified
7985 (start and end attributes are now stored directly as Py_ssize_t
7986 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00007987
Georg Brandl3ee81df2008-05-17 18:14:43 +00007988- Issue #829951: In the smtplib module, SMTP.starttls() now complies
7989 with RFC 3207 and forgets any knowledge obtained from the server not
7990 obtained from the TLS negotiation itself. Patch contributed by Bill
7991 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00007992
Georg Brandl3ee81df2008-05-17 18:14:43 +00007993- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00007994 that the SMTP.starttls() caller no longer needs to call ehlo()
7995 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00007996 does not claim to support starttls. Adds the
7997 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
7998 Fenner.

8078 complex, tuple, list, dict, set, and frozenset. Formerly, it would
8079 silently miscode subclasses of those types. Now, it raises a
8080 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00008081

Georg Brandl3ee81df2008-05-17 18:14:43 +00008096 time so that opening a database previously created with the DB_DUP
8097 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8098 opens. Specifically: dictionary assignment to a DB object will
8099 replace all values for a given key when the database allows
8100 duplicate values. DB users should use DB.put(k, v) when they want
8101 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00008102

8108 characters with ASCII value less than 32. Also, it correctly quotes
8109 dots only if they occur on a single line, as opposed to the previous
8110 behavior of quoting dots if they are the second character of any
8111 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00008112

Georg Brandl3ee81df2008-05-17 18:14:43 +00008517- Removed the macfs module. It had been deprecated since Python 2.5.
8518 This lead to the deprecation of macostools.touched() as it relied
8519 solely on macfs and was a no-op under OS X.
