Mark Dickinsondbbed042011-09-19 16:38:08 +0100612- Issue #12973: Fix overflow checks that invoked undefined behaviour in
613 int.__pow__. These overflow checks were causing int.__pow__ to produce
614 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +0100615 compiler optimizing the check away. Also fix similar overflow checks
616 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
617 bugs caused test failures with recent versions of Clang.

629 cleared by the garbage collector. This fixes a segfault when an instance
630 and its type get caught in a reference cycle, and the instance's
631 deallocator calls one of the methods on the type (e.g. when subclassing

Florent Xiclunac2279652012-02-12 14:49:03 +0100685- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +0100686 has left two versions of customize_compiler, the original in
687 distutils.sysconfig and another copy in distutils.ccompiler, with some

690 is the case in 3.x.
691
Ned Deily0d0ea482012-02-10 12:59:06 +0100692- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
693 Distutils-based packages with C extension modules may fail because
694 Apple has removed gcc-4.2, the version used to build python.org
695 64-bit/32-bit Pythons. If the user does not explicitly override
696 the default C compiler by setting the CC environment variable,
697 Distutils will now attempt to compile extension modules with clang
698 if gcc-4.2 is required but not found. Also as a convenience, if
699 the user does explicitly set CC, substitute its value as the default
700 compiler in the Distutils LDSHARED configuration variable for OS X.
701 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
702 SDK, neither of which are available in Xcode 4. This change does not
703 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -0700976- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
977 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
978 interpreter process. This could cause failures in non-Distutils subprocesses
979 and was unreliable since tests or user programs could modify the interpreter
980 environment after Distutils set it. Instead, have Distutils set the the
981 deployment target only in the environment of each build subprocess. It is
982 still possible to globally override the default by setting
983 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
984 greater or equal to the default value, the value with which the interpreter
985 was built.

1014 updating the check interval, so if the user decreases the check interval,
1015 the ticker doesn't have to wind down to zero from the old starting point
1016 before the new interval takes effect. And if the user increases the
1017 interval, it makes sure the new limit takes effect right away rather have an
1018 early task switch before recognizing the new interval.

1968
Raymond Hettinger20397532010-09-12 02:11:45 +00001969- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
1970 This prevents user-created self-referencing ordered dictionaries from
1971 becoming permanently uncollectable GC garbage. The downside is that
1972 removing __del__ means that the internal doubly-linked list has to wait for
1973 GC collection rather than freeing memory immediately when the refcnt drops
1974 to zero.

1982 to fetch the original errno, or to filter timeout errors. Now the
1983 original error is re-raised.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00002433- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
2434 start byte and the continuation byte(s) are now considered invalid, instead
2435 of the number of bytes specified by the start byte.
2436 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
2437 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
2438 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
2439 Previous versions returned a single u'\ufffd'.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00002447- Issue #8748: Fix two issues with comparisons between complex and integer
2448 objects. (1) The comparison could incorrectly return True in some cases
2449 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
2450 (2) The comparison raised an OverflowError for large integers, leading
2451 to unpredictable exceptions when combining integers and complex objects
2452 in sets or dicts.

Mark Dickinson81336372010-05-30 12:12:25 +00002454- Issue #5211: Implicit coercion for the complex type is now completely

Georg Brandlba83f822010-03-14 09:50:54 +00003332 file position when calling `truncate()`. It would previously change the file
3333 position to the given argument, which goes against the tradition of

3337 class used to represent files stored inside an archive. The new
3338 implementation is significantly faster and can be wrapped in a
3339 ``io.BufferedReader`` object for more speedups. It also solves an issue
3340 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00003431- The ``__complex__()`` method is now looked up on the class of instances to
3432 make it consistent with other special methods.

3436
Mark Dickinson1b34d252010-01-01 17:27:30 +00003437- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00003438 DeprecationWarning when passed a float argument where an integer was expected.
3439 These functions and methods now raise TypeError instead. The majority of the
3440 effects of this change are in the extension modules, but some core functions
3441 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3442 and many unicode/str methods.

3457 least on IEEE 754 platforms), and in particular does not depend on the
3458 internal representation of a long.

3466
Georg Brandlba83f822010-03-14 09:50:54 +00003467 These executables now work properly with the arch(1) command: ``arch -ppc

3555 ``PyArg_ParseTupleAndKeywords()``, ``PyArg_VaParse()``,
3556 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept
3557 float arguments for integer format codes (other than 'L'): previously an
3558 attempt to pass a float resulted in a DeprecationWarning; now it gives a
3559 TypeError. For the 'L' format code (which previously had no warning) there is
3560 now a DeprecationWarning.

3609 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00003610
Georg Brandlba83f822010-03-14 09:50:54 +00003611- Remove switch from "%f" formatting to "%g" formatting for floats larger than
3612 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +00003613
Georg Brandlba83f822010-03-14 09:50:54 +00003614- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
3615 1e-100 used to raise OverflowError, but now gives the requested 120
3616 significant digits instead.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00003624
Georg Brandlba83f822010-03-14 09:50:54 +00003625- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3626 decimal string that's guaranteed to round back to x under correct rounding
3627 (with round-half-to-even rounding mode). Previously it gave a string based on
3628 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3629 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3630 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003631
Georg Brandlba83f822010-03-14 09:50:54 +00003632- Issue #7117: On almost all platforms: float-to-string and string-to-float
3633 conversions within Python are now correctly rounded. Places these conversions
3634 occur include: str for floats and complex numbers; the float and complex
3635 constructors; old-style and new-style numeric formatting; serialization and
3636 deserialization of floats and complex numbers using marshal, pickle and json;
3637 parsing of float and imaginary literals in Python code; Decimal-to-float
3638 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003639
Georg Brandlba83f822010-03-14 09:50:54 +00003640 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3641 providing correctly-rounded strtod and dtoa C functions. This code is
3642 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3643 the C compiler. There may be a small number of platforms on which correct
3644 operation of this code cannot be guaranteed, so the code is not used: notably,
3645 this applies to platforms where the C double format is not IEEE 754 binary64,
3646 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3647 and Python's configure script is unable to determine how to change the FPU
3648 precision. On these platforms conversions use the platform strtod and dtoa,
3649 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003650
Georg Brandlba83f822010-03-14 09:50:54 +00003651- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3652 uses the correctly-rounded string <-> float conversions described above (when
3653 available), and so produces correctly rounded results that will display nicely
3654 under the float repr. There are two related small changes: (1) round now
3655 accepts any class with an ``__index__()`` method for its second argument (but
3656 no longer accepts floats for the second argument), and (2) an excessively
3657 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3658 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00003788- Issue #5829: complex("1e500") no longer raises OverflowError. This makes it
3789 consistent with float("1e500") and interpretation of real and imaginary
3790 literals.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00003799- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
Mark Dickinsonb1d45852009-05-11 15:33:08 +00003800
Georg Brandlba83f822010-03-14 09:50:54 +00003801 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
3802 (2) parsing of strings representing infinities and nans was locale aware; and
3803 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00003805- Issue #5920: For ``float.__format__()``, change the behavior with the empty
3806 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
3807 but with at least one decimal point and with a default precision
3808 of 12. Previously, the behavior the same but with a default precision of 6.
3809 This more closely matches ``str()``, and reduces surprises when adding
3810 alignment flags to the empty presentation type. This also affects the new
3811 complex.__format__ in the same way.
3812
3813- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
3814 classtype's, even if it was None. property now inserts the __doc__ into the
3815 subclass instance __dict__.

Georg Brandlba83f822010-03-14 09:50:54 +00003876 untrackable objects are not tracked by the garbage collector. This can reduce
3877 the size of collections and therefore the garbage collection overhead on

3885 internal representation of integers, for performance reasons. Base 2**30 is
3886 enabled by default on 64-bit machines. Add --enable-big-digits option to
3887 configure, which overrides the default. Add sys.long_info structseq to
3888 provide information about the internal format.

Georg Brandlba83f822010-03-14 09:50:54 +00004035- On windows, ``os.chdir()`` given unicode was not working if

4037 this code path is really executed because I cannot move to such directory on
4038 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00004040- Issue #4069: When ``set.remove(element)`` is used with a set element, the
4041 element is temporarily replaced with an equivalent frozenset. But the
4042 eventual KeyError would always report the empty ``frozenset()`` as the missing
4043 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00004063- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
4064 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
4065 step. This avoids problems with counting UTF-8 bytes that ignores the effect
4066 of using the replace error handler in PyUnicode_DecodeUTF8().
4067
Walter Dörwald726ba8e2009-05-06 14:32:35 +00004068- Issue #3739: The unicode-internal encoder now reports the number of characters

4070
Georg Brandlba83f822010-03-14 09:50:54 +00004071- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
4072 allocator will be automatically disabled when running under Valgrind. This
4073 gives improved memory leak detection when running under Valgrind, while taking
4074 advantage of pymalloc at other times.

Georg Brandlba83f822010-03-14 09:50:54 +00005238 - If x is not an int, long or float, then packing x will always result in
5239 struct.error. Previously an x with an __int__ method could be packed by
5240 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
5241 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
5242 neither __int__ nor __long__, TypeError used to be raised (with a
5243 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
5244 struct.error in other cases.

5247 argument with an __int__ method can be packed, but use of this feature
5248 triggers a DeprecationWarning.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00005439- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
5440
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005441- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5442 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5443 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5444 ``printf`` function, whereas PyString_FromFormat has an independent
5445 implementation and uses "%zd" on all platforms for size_t values.
5446 This makes a difference on win64, where ``printf`` needs "%Id" to display
5447 64bit values.
5448
Benjamin Peterson97179b02008-09-09 20:55:01 +00005449- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
5450 error.
5451
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00005452- Issue #3777: long() applied to a float object now always return a long
5453 object; previously an int would be returned for small values. the __long__
5454 method is allowed to return either an int or a long, but the behaviour of
5455 float objects should not change to respect backward compatibility.
5456
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00005457- Issue #3751: str.rpartition would perform a left-partition when called with
5458 a unicode argument.
5459
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00005460- Issue #3683: Fix compilation when --without-threads is given.

Vinay Sajip35e3b032008-09-01 14:33:59 +00005463 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005464 was correctly parsed but parsing of subsequent arguments failed.
5465
Vinay Sajip35e3b032008-09-01 14:33:59 +00005466- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005467 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5468 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5469 when given a tuple of classes as second argument, were looking up
5470 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5471 type object.
5472
Neal Norwitz18aa3882008-08-24 05:04:52 +00005473- Fix crashes on memory allocation failure found with failmalloc.

Brett Cannon1eaf0742008-09-02 01:25:16 +00005542 warnings.catch_warnings() along with some API cleanup. Expanding the tests
5543 for catch_warnings() also led to an improvement in the raising of a
5544 DeprecationWarning related to warnings.warn_explicit().
5545

5616-----------------
5617
Guido van Rossumf8402962008-08-20 15:01:50 +00005618- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5619 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5620 extensions do not automatically benefit from the class attribute
5621 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5622 to their tp_flags field if they care. This is a backwards
5623 compatibility feature; in 3.0, all types will use the cache by
5624 default.
5625
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005626- Keyword arguments can now follow starred arguments. (``f(a, *args,
5627 keyword=23)`` is now valid syntax.)
5628
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005629- ctypes function pointers that are COM methods have a boolean True
5630 value again.
5631
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005632- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5633 by denying s# to parse objects that have a releasebuffer procedure,
5634 and introducing s*.
5635
Georg Brandl1e13ea92008-08-11 09:07:59 +00005636- Issue #3537: Fix an assertion failure when an empty but presized dict
5637 object was stored in the freelist.
5638
Mark Dickinsonb6467572008-08-04 21:30:09 +00005639- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5640 ValueError consistently across platforms.
5641
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005642- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5643 (64bit Unix, for example), unichr() would truncate its argument and return
5644 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5645
Neal Norwitze7d8be82008-07-31 17:17:14 +00005646- Apply security patches from Apple.
5647
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005648- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5649 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5650
Antoine Pitrou92f82162008-07-25 22:22:08 +00005651- Issue #1819: function calls with several named parameters are now on
5652 average 35% faster (as measured by pybench).
5653
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005654- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5655 the python debugger steps into a class statement: the free variables (local
5656 variables defined in an outer scope) would be deleted from the outer scope.
5657
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005658- Issue #2620: Overflow checking when allocating or reallocating memory
5659 was not always being done properly in some python types and extension
5660 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5661 all been updated to perform better checks and places in the code that
5662 would previously leak memory on the error path when such an allocation
5663 failed have been fixed.

5667
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00005668- Issue #3612: Added some missing basic types in ctypes.wintypes.
5669
Benjamin Petersone977ad42008-08-20 01:42:01 +00005670- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5671 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5672
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005673- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5674 version reported by these tools does not necessarily follow the python
5675 version numbering scheme, so the module is less strict when parsing it.
5676
Nick Coghlanf70385a2008-08-18 12:42:46 +00005677- Issue #2235: Added Py3k warnings for types which will become unhashable
5678 under the stricter __hash__ inheritance rules in 3.0. Several types
5679 which did not meet the rules for hash invariants and were already
5680 unhashable in 3.0 have now been explicitly flagged as unhashable in
5681 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5682 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5683
Brett Cannon88f801d2008-08-18 00:46:22 +00005684- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

5797
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00005798- Issue #643841: The language reference now provides more detailed

5810-----------------
5811
Georg Brandl3e483f62008-07-16 22:57:41 +00005812- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5813 its methods now allow for items objects that can be converted to
5814 an integer using operator.index().
5815
Mark Dickinson64b7e502008-07-16 09:40:03 +00005816- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5817 produced a ValueError instead of giving the correct float.
5818
Eric Smitha5fa5a22008-07-16 00:11:49 +00005819- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5820 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5821
Mark Dickinson7103aa42008-07-15 19:08:33 +00005822- Issue #3008: the float type has a new instance method 'float.hex'
5823 and a new class method 'float.fromhex' to convert floating-point
5824 numbers to and from hexadecimal strings, respectively.
5825
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005826- Issue #2235: __hash__ is once again inherited by default. To allow
5827 collections.Hashable to remain meaningful in the presence of the
5828 default hash implementation (object.__hash__), it is now possible
5829 to explicit block inheritance of hash by setting __hash__=None at
5830 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5831 level.
5832
Nick Coghlanb028f502008-07-13 14:52:36 +00005833- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5834 the parent module cannot be found while performing an absolute import.
5835 This means that an incorrectly defined __package__ attribute will
5836 now only prevent relative imports in that module rather than causing
5837 all imports from that module to fail.
5838
Nick Coghlan14ff9942008-07-08 14:21:42 +00005839- Issue #2517: Allow unicode messages in Exceptions again by correctly

5849 another thread's dictionary.
5850
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005851- Issue #3004: Minor change to slice.indices(): the start and stop
5852 arguments are now treated identically, making the behaviour easier
5853 to describe and understand. For example, slice(None, -10,
5854 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5855 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5856 10, -1).
5857
Georg Brandl278fc502008-07-19 12:46:12 +00005858- Issue #3219: Calling a function with repeated keyword arguments,
5859 f(a=2, a=23), would not cause a syntax error. This was a regression
5860 from 2.4 caused by the switch to the new compiler.

5899 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005900 wrong because the actual transmitted size could differ from the

Ronald Oussoren5640ce22008-06-05 12:58:24 +00006308- On MacOS X it is now possible to install the framework in 64-bit
6309 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00006310 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006311
6312 This is controlled by the configure argument ``--with-universal-archs``:
6313
6314 - ``--with-universal-archs=all``: install 4-way universal
6315
6316 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6317
6318 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6319
6320 This option should be used in combination with ``--enable-universalsdk=``.
6321
6322 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 +00006372- Issue #1631171: Re-implement the 'warnings' module in C (the
6373 original Python code has been kept as backup). This will allow for
6374 using the 'warning's machinery in such places as the parser where
6375 use of pure Python code is not possible. Both the ``showarning()``
6376 and ``formatwarning()`` gain an optional 'line' argument which is
6377 not called by default for backwards-compatibility reasons. Setting
6378 ``warnings.showwarning()`` to an implementation that lacks support
6379 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006442- Issue #2550: The approach used by client/server code for obtaining
6443 ports to listen on in network-oriented tests has been refined in an
6444 effort to facilitate running multiple instances of the entire
6445 regression test suite in parallel without issue.
6446 test_support.bind_port() has been fixed such that it will always
6447 return a unique port -- which wasn't always the case with the
6448 previous implementation, especially if socket options had been set
6449 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6450 new implementation of bind_port() will actually raise an exception
6451 if it is passed an AF_INET/SOCK_STREAM socket with either the
6452 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6453 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6454 the socket it's been passed. This currently only applies to
6455 Windows. This option prevents any other sockets from binding to the
6456 host/port we've bound to, thus removing the possibility of the
6457 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6458 when a second SOCK_STREAM socket binds and accepts to a host/port
6459 that's already been bound by another socket. The optional preferred
6460 port parameter to bind_port() has been removed. Under no
6461 circumstances should tests be hard coding ports!
6462
6463 test_support.find_unused_port() has also been introduced, which will
6464 pass a temporary socket object to bind_port() in order to obtain an
6465 unused port. The temporary socket object is then closed and
6466 deleted, and the port is returned. This method should only be used
6467 for obtaining an unused port in order to pass to an external program
6468 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6469 a parameter to a server-oriented class that doesn't give you direct
6470 access to the underlying socket used.
6471
6472 Finally, test_support.HOST has been introduced, which should be used
6473 for the host argument of any relevant socket calls (i.e. bind and
6474 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006475
6476 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006477 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006478 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6479 test_asynchat and test_socket_ssl.
6480
Georg Brandl3ee81df2008-05-17 18:14:43 +00006481 It is now possible for multiple instances of the regression test
6482 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00006536- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00006537 \Uxxxxxxxx did not accept values outside the Basic Multilingual
6538 Plane. This affected raw unicode literals and the
6539 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
6540 this case, like normal unicode literals and the 'unicode-escape'
6541 codec.

Eric Smitha73fbe72008-02-23 03:09:44 +00006761- Added the future_builtins module, which contains hex() and oct().
6762 These are the PEP 3127 version of these functions, designed to be
6763 compatible with the hex() and oct() builtins from Python 3.0. They
6764 differ slightly in their output formats from the existing, unchanged
6765 Python 2.6 builtins. The expected usage of the future_builtins
6766 module is:
6767 from future_builtins import hex, oct
6768
Eric Smith7ef40bf2008-02-20 23:34:22 +00006769- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6770 exponents for exponents with absolute value < 100. Follows C99
6771 standard. This is a change on Windows, which would use 3 digits.
6772 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6773 so that any alterations it does to the resulting string will be
6774 available in stringlib/formatter.h (for float.__format__).
6775
Eric Smith5a3c1352008-02-19 13:21:56 +00006776- Implemented PEP 3101, Advanced String Formatting. This adds a new
6777 builtin format(); a format() method for str and unicode; a
6778 __format__() method to object, str, unicode, int, long, float, and
6779 datetime; the class string.Formatter; and the C API
6780 PyObject_Format().
6781
Georg Brandl3ee81df2008-05-17 18:14:43 +00006782- Fixed several potential crashes, all caused by specially crafted
6783 __del__ methods exploiting objects in temporarily inconsistent
6784 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006785
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006786- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006787 prevent a possible crash: an Abstract Base Class would try to access
6788 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00006789

Georg Brandl3ee81df2008-05-17 18:14:43 +00006793- Clear all free lists during a gc.collect() of the highest generation
6794 in order to allow pymalloc to free more arenas. Python may give back
6795 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006796
Georg Brandl3ee81df2008-05-17 18:14:43 +00006797- Issue #2045: Fix an infinite recursion triggered when printing a
6798 subclass of collections.defaultdict, if its default_factory is set
6799 to a bound method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006827- Patch #1473257: generator objects gain a gi_code attribute. This is
6828 the same object as the func_code attribute of the function that
6829 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006830
Georg Brandl3ee81df2008-05-17 18:14:43 +00006831- Issue #1920: "while 0" statements were completely removed by the
6832 compiler, even in the presence of an "else" clause, which is
6833 supposed to be run when the condition is false. Now the compiler
6834 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006835
Guido van Rossumeead05f2008-01-24 18:21:02 +00006836- A few crashers fixed: weakref_in_del.py (issue #1377858);
6837 loosing_dict_ref.py (issue #1303614, test67.py);
6838 borrowed_ref_[34].py (not in tracker).
6839
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006840- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006841 suppressed while an extension is loaded by calling SetErrorMode in

6843
Georg Brandl3ee81df2008-05-17 18:14:43 +00006844- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006845 several extension methods and modules do not work without unicode
6846 support.
6847
Georg Brandl26543b12008-01-21 18:36:51 +00006848- Issue #1882: when compiling code from a string, encoding cookies in the

6852
Georg Brandl6caad7d2008-01-26 14:19:22 +00006853- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006854 added.
6855
Christian Heimesc94e2b52008-01-14 04:13:37 +00006856- sys.float_info / PyFloat_GetInfo: The floating point information
6857 object was converted from a dict to a specialized structseq object.
6858
Georg Brandl3ee81df2008-05-17 18:14:43 +00006859- Patch #1816: Added sys.flags structseq. It exposes the status of
6860 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006861
Georg Brandl3ee81df2008-05-17 18:14:43 +00006862- Objects/structseq.c: Implemented new structseq representation. The
6863 patch makes structseqs (e.g. the return value of os.stat) more
6864 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006865
Georg Brandl3ee81df2008-05-17 18:14:43 +00006866- Patch #1700288: added a type attribute cache that caches method
6867 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00006868
Neal Norwitz3fc15b82008-01-10 05:42:58 +00006869- Bug #1776: __import__() no longer accepts filenames on any platform.

6875 envvar and sys.dont_write_bytecode attribute. All these can be set
6876 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006877
Georg Brandl3ee81df2008-05-17 18:14:43 +00006878- Improve some exception messages when Windows fails to load an
6879 extension module. Now we get for example '%1 is not a valid Win32
6880 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00006887- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006888 and INF. float("nan"), float("inf") and float("-inf") now work on
6889 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006890
Georg Brandl3ee81df2008-05-17 18:14:43 +00006891- Compiler now generates simpler and faster code for dictionary

6937
Georg Brandl21e99f42010-03-07 15:23:59 +00006938- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006939 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6940 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006941
Georg Brandl3ee81df2008-05-17 18:14:43 +00006942- Issue #1686386: Tuple's tp_repr did not take into account the
6943 possibility of having a self-referential tuple, which is possible
6944 from C code. Nor did object's tp_str consider that a type's tp_str
6945 could do something that could lead to an inifinite recursion.
6946 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6947 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006948
Georg Brandl3ee81df2008-05-17 18:14:43 +00006949- Issue #1164: It was possible to trigger deadlock when using the
6950 'print' statement to write to a file since the GIL was not released
6951 as needed. Now PyObject_Print() does the right thing along with
6952 various tp_print implementations of the built-in types and those in
6953 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006954

Georg Brandl3ee81df2008-05-17 18:14:43 +00006963 PyObject_Call() never calling back out to Python code to trigger
6964 recursion depth updates/checks. Required the creation of a static
6965 RuntimeError instance in case normalizing an exception put the
6966 recursion check value past its limit. Fixes crashers
6967 infinite_rec_(1|2|4|5).py.

Guido van Rossum143b5642007-03-23 04:58:42 +00007015- Bug #1683368: The object.__init__() and object.__new__() methods are
7016 now stricter in rejecting excess arguments. The only time when
7017 either allows excess arguments is when it is not overridden and the
7018 other one is. For backwards compatibility, when both are
7019 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007020 warning later). Also, type.__init__() insists on the same signature
7021 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00007023- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7024 object to complex using its __complex__() method before falling back
7025 to the __float__() method. Therefore, the functions in the cmath
7026 module now can operate on objects that define a __complex__()
7027 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00007045- Bug #1678647: write a newline after printing an exception in any
7046 case, even when converting the value to a string failed.
7047
Georg Brandl871f1bc2007-03-12 13:17:36 +00007048- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007049 its argument, if it exists. If not, it will work like before. This
7050 allows customizing the output of dir() in the presence of a
7051 __getattr__().

7061 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00007062
Georg Brandlaa2321b2007-03-07 00:40:28 +00007063- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007064 makes the filenames the warning module prints much more sensible
7065 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00007066

Georg Brandl0fca97a2007-03-05 22:28:08 +00007078- Patch #1674228: when assigning a slice (old-style), check for the
7079 sq_ass_slice instead of the sq_slice slot.
7080
Georg Brandl3ee81df2008-05-17 18:14:43 +00007081- When printing an unraisable error, don't print exceptions. before
7082 the name. This duplicates the behavior whening normally printing
7083 exceptions.

Georg Brandl2c1375c2006-10-12 11:27:59 +00007133- Bug #1545497: when given an explicit base, int() did ignore NULs
7134 embedded in the string to convert.
7135
Georg Brandl846f73a2006-10-08 07:11:54 +00007136- Bug #1569998: break inside a try statement (outside a loop) is now

Neal Norwitzdac090d2006-09-05 03:53:08 +00007183- Bug #1520864: unpacking singleton tuples in list comprehensions and
Georg Brandl3ee81df2008-05-17 18:14:43 +00007184 generator expressions (x for x, in ... ) works again. Fixing this
7185 problem required changing the .pyc magic number. This means that
7186 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007989- The implementation of UnicodeError objects has been simplified
7990 (start and end attributes are now stored directly as Py_ssize_t
7991 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00007992
Georg Brandl3ee81df2008-05-17 18:14:43 +00007993- Issue #829951: In the smtplib module, SMTP.starttls() now complies
7994 with RFC 3207 and forgets any knowledge obtained from the server not
7995 obtained from the TLS negotiation itself. Patch contributed by Bill
7996 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00007997
Georg Brandl3ee81df2008-05-17 18:14:43 +00007998- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00007999 that the SMTP.starttls() caller no longer needs to call ehlo()
8000 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00008001 does not claim to support starttls. Adds the
8002 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
8003 Fenner.

8083 complex, tuple, list, dict, set, and frozenset. Formerly, it would
8084 silently miscode subclasses of those types. Now, it raises a
8085 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00008086

Georg Brandl3ee81df2008-05-17 18:14:43 +00008101 time so that opening a database previously created with the DB_DUP
8102 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8103 opens. Specifically: dictionary assignment to a DB object will
8104 replace all values for a given key when the database allows
8105 duplicate values. DB users should use DB.put(k, v) when they want
8106 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00008107

8113 characters with ASCII value less than 32. Also, it correctly quotes
8114 dots only if they occur on a single line, as opposed to the previous
8115 behavior of quoting dots if they are the second character of any
8116 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00008117

8507 builds.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008522- Removed the macfs module. It had been deprecated since Python 2.5.
8523 This lead to the deprecation of macostools.touched() as it relied
8524 solely on macfs and was a no-op under OS X.
