Ned Deily18fae3f2013-01-31 01:24:55 -0800738- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
739 In particular, fix extension module build failures when trying to use
740 32-bit-only installer Pythons on systems with Xcode 4 (currently
741 OS X 10.8, 10.7, and optionally 10.6).
742 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
743 * Since Xcode 4 removes ppc support, extension module builds now
744 check for ppc compiler support and by default remove ppc and
745 ppc64 archs when they are not available.
746 * Extension module builds now revert to using system installed
747 headers and libs (/usr and /System/Library) if the SDK used
748 to build the interpreter is not installed or has moved.
749 * Try to avoid building extension modules with deprecated
750 and problematic Apple llvm-gcc compiler. If original compiler
751 is not available, use clang instead by default.

995 int.__pow__. These overflow checks were causing int.__pow__ to produce
996 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +0100997 compiler optimizing the check away. Also fix similar overflow checks
998 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

1011 cleared by the garbage collector. This fixes a segfault when an instance
1012 and its type get caught in a reference cycle, and the instance's
1013 deallocator calls one of the methods on the type (e.g. when subclassing

Florent Xiclunac2279652012-02-12 14:49:03 +01001067- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +01001068 has left two versions of customize_compiler, the original in
1069 distutils.sysconfig and another copy in distutils.ccompiler, with some
1070 parts of distutils calling one and others using the other.
1071 Complete the revert back to only having one in distutils.sysconfig as
1072 is the case in 3.x.
1073
Ned Deily0d0ea482012-02-10 12:59:06 +01001074- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
1075 Distutils-based packages with C extension modules may fail because
1076 Apple has removed gcc-4.2, the version used to build python.org
1077 64-bit/32-bit Pythons. If the user does not explicitly override
1078 the default C compiler by setting the CC environment variable,
1079 Distutils will now attempt to compile extension modules with clang
1080 if gcc-4.2 is required but not found. Also as a convenience, if
1081 the user does explicitly set CC, substitute its value as the default
1082 compiler in the Distutils LDSHARED configuration variable for OS X.
1083 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
1084 SDK, neither of which are available in Xcode 4. This change does not
1085 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001358- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1359 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1360 interpreter process. This could cause failures in non-Distutils subprocesses
1361 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02001362 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07001363 deployment target only in the environment of each build subprocess. It is
1364 still possible to globally override the default by setting
1365 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1366 greater or equal to the default value, the value with which the interpreter
1367 was built.

1397 the ticker doesn't have to wind down to zero from the old starting point
1398 before the new interval takes effect. And if the user increases the
1399 interval, it makes sure the new limit takes effect right away rather have an
1400 early task switch before recognizing the new interval.

Raymond Hettinger20397532010-09-12 02:11:45 +00002351- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
2352 This prevents user-created self-referencing ordered dictionaries from
2353 becoming permanently uncollectable GC garbage. The downside is that
2354 removing __del__ means that the internal doubly-linked list has to wait for
2355 GC collection rather than freeing memory immediately when the refcnt drops
2356 to zero.
2357

2385 falling into recursion.
2386
R. David Murray7c4bf552010-08-25 01:45:57 +00002387- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
2388 character years even if the message contains RFC822 two character years.
2389
Daniel Stutzbach91287322010-08-24 21:09:30 +00002390- Issue #8750: Fixed MutableSet's methods to correctly handle

Antoine Pitroucb4f47c2010-08-11 13:40:17 +00002422- Issue #9550: a BufferedReader could issue an additional read when the
2423 original read request had been satisfied, which could block indefinitely
2424 when the underlying raw IO channel was e.g. a socket. Report and original
2425 patch by Jason V. Miller.

2818 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
2819 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte

2831 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

R. David Murray1a14d3d2010-04-12 16:35:19 +00003128- Issue #7585: difflib context and unified diffs now place a tab between
Georg Brandlfee0f442010-05-22 21:26:21 +00003129 filename and date, conforming to the 'standards' they were originally designed
3130 to follow. This improves compatibility with patch tools.

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00003176 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
3177 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
3178 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

3200
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00003201- Issue #7301: Add environment variable $PYTHONWARNINGS.
3202
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00003203- Issue #8329: Don't return the same lists from select.select when no fds are
3204 changed.
3205
Georg Brandlfee0f442010-05-22 21:26:21 +00003206- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00003207 on 64-bit machines. The shift count for either left or right shift is
3208 permitted to be up to sys.maxsize.
3209
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00003210- Ensure that tokenization of identifiers is not affected by locale.
3211
Georg Brandlfee0f442010-05-22 21:26:21 +00003212- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00003213
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00003214- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
3215
Georg Brandlfee0f442010-05-22 21:26:21 +00003216- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3217 with a non-empty format string. This is an effort to future-proof user
3218 code. If a derived class does not currently implement __format__ but later
3219 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00003220 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00003221 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00003222
Antoine Pitroua57df2c2010-03-31 21:32:15 +00003223- Issue #8268: Old-style classes (not just instances) now support weak

Victor Stinner66644262010-03-10 22:30:19 +00003236- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00003237 (SIGINT). If an error occurs while importing the site module, the error is

Georg Brandlfee0f442010-05-22 21:26:21 +00003254- Issue #8257: The Decimal construct now accepts a float instance directly,
3255 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00003256
3257 >>> Decimal(1.1)
3258 Decimal('1.100000000000000088817841970012523233890533447265625')
3259
Raymond Hettinger34c35b22010-04-03 10:22:00 +00003260- collections.Counter() now supports a subtract() method.
3261
Georg Brandlfee0f442010-05-22 21:26:21 +00003262- The functools module now has a total_ordering() class decorator to simplify
3263 the specification of rich comparisons.

Georg Brandlfee0f442010-05-22 21:26:21 +00003265- The functools module also adds cmp_to_key() as a tool to transition old-style
3266 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00003267
Georg Brandlfee0f442010-05-22 21:26:21 +00003268- Issue #8294: The Fraction constructor now accepts Decimal and float instances
3269 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00003270
Georg Brandlfee0f442010-05-22 21:26:21 +00003271- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3272 InvalidOperation instead of returning False. (Comparisons involving a quiet
3273 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3274 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00003275
Georg Brandlfee0f442010-05-22 21:26:21 +00003276- Issue #2531: Comparison operations between floats and Decimal instances now
3277 return a result based on the numeric values of the operands; previously they
3278 returned an arbitrary result based on the relative ordering of id(float) and
3279 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00003280
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00003281- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00003282 argument `-` which tells it to read files to compile from stdin. Each line is
3283 read on demand and the named file is compiled immediately. (Original patch by
3284 Piotr Ożarowski).

Florent Xicluna58b65662010-03-30 16:29:03 +00003289- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
3290 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00003291 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00003292
Georg Brandlfee0f442010-05-22 21:26:21 +00003293- Comparisons using one of <, <=, >, >= between a complex instance and a
3294 Fractions instance now raise TypeError instead of returning True/False. This
3295 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3296 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00003364- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from

Mark Dickinson4846a8e2010-04-03 14:05:10 +00003395- Issue #8300: When passing a non-integer argument to struct.pack with any
3396 integer format code, struct.pack first attempts to convert the non-integer

Georg Brandlba83f822010-03-14 09:50:54 +00003400- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
3401 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
3402 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00003403 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
3404 inconsistent: __int__ was used for some integer codes but not for others, and
3405 the set of integer codes for which it was used differed between native packing
3406 and standard packing.)

3659 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
3660 returning NULL. The macro now returns a statically allocated empty string
3661 instead.

Georg Brandlba83f822010-03-14 09:50:54 +00003707 specified, rather than fall through to AF_PACKET (in the ``socket`` module).

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003713- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00003714 file position when calling `truncate()`. It would previously change the file
3715 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00003716 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
3717
Georg Brandlba83f822010-03-14 09:50:54 +00003718- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
3719 class used to represent files stored inside an archive. The new
3720 implementation is significantly faster and can be wrapped in a
3721 ``io.BufferedReader`` object for more speedups. It also solves an issue
3722 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
3723 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +00003733- Issue #7748: Since unicode values are supported for some metadata options in
3734 Distutils, the DistributionMetadata get_* methods will now return an utf-8
3735 encoded string for them. This ensures that the upload and register commands
3736 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00004007- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
4008 decimal string that's guaranteed to round back to x under correct rounding
4009 (with round-half-to-even rounding mode). Previously it gave a string based on
4010 rounding x to 17 decimal digits. repr(x) for a complex number behaves
4011 similarly. On platforms where the correctly-rounded strtod and dtoa code is
4012 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004013
Georg Brandlba83f822010-03-14 09:50:54 +00004014- Issue #7117: On almost all platforms: float-to-string and string-to-float
4015 conversions within Python are now correctly rounded. Places these conversions
4016 occur include: str for floats and complex numbers; the float and complex
4017 constructors; old-style and new-style numeric formatting; serialization and
4018 deserialization of floats and complex numbers using marshal, pickle and json;
4019 parsing of float and imaginary literals in Python code; Decimal-to-float
4020 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004021
Georg Brandlba83f822010-03-14 09:50:54 +00004022 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4023 providing correctly-rounded strtod and dtoa C functions. This code is
4024 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4025 the C compiler. There may be a small number of platforms on which correct
4026 operation of this code cannot be guaranteed, so the code is not used: notably,
4027 this applies to platforms where the C double format is not IEEE 754 binary64,
4028 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4029 and Python's configure script is unable to determine how to change the FPU
4030 precision. On these platforms conversions use the platform strtod and dtoa,
4031 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00004033- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4034 uses the correctly-rounded string <-> float conversions described above (when
4035 available), and so produces correctly rounded results that will display nicely
4036 under the float repr. There are two related small changes: (1) round now
4037 accepts any class with an ``__index__()`` method for its second argument (but
4038 no longer accepts floats for the second argument), and (2) an excessively
4039 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4040 raises an exception.

4189 but with at least one decimal point and with a default precision
4190 of 12. Previously, the behavior the same but with a default precision of 6.
4191 This more closely matches ``str()``, and reduces surprises when adding

Georg Brandl29c6a282009-04-05 20:23:13 +00004302- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +00004303 were suppressing all exceptions. These include list(), filter(), map(),

Georg Brandlba83f822010-03-14 09:50:54 +00004333- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
4334 existing .py counterpart, override the co_filename attributes of all code
4335 objects if the original filename is obsolete (which can happen if the file has

4384
Georg Brandlba83f822010-03-14 09:50:54 +00004385- Issue #3689: The list reversed iterator now supports __length_hint__ instead

4390
Georg Brandlba83f822010-03-14 09:50:54 +00004391- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
4392 file objects with closefd=False. The file descriptor is still kept open but
4393 the file object behaves like a closed file. The ``FileIO`` object also got a
4394 new readonly attribute ``closefd``.

4413
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00004414- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00004417- On windows, ``os.chdir()`` given unicode was not working if
4418 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
4419 this code path is really executed because I cannot move to such directory on
4420 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00004422- Issue #4069: When ``set.remove(element)`` is used with a set element, the
4423 element is temporarily replaced with an equivalent frozenset. But the
4424 eventual KeyError would always report the empty ``frozenset()`` as the missing
4425 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00004445- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
4446 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
4447 step. This avoids problems with counting UTF-8 bytes that ignores the effect
4448 of using the replace error handler in PyUnicode_DecodeUTF8().
4449
Walter Dörwald726ba8e2009-05-06 14:32:35 +00004450- Issue #3739: The unicode-internal encoder now reports the number of characters

4452
Georg Brandlba83f822010-03-14 09:50:54 +00004453- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
4454 allocator will be automatically disabled when running under Valgrind. This
4455 gives improved memory leak detection when running under Valgrind, while taking
4456 advantage of pymalloc at other times.

5822
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005823- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5824 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5825 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5826 ``printf`` function, whereas PyString_FromFormat has an independent
5827 implementation and uses "%zd" on all platforms for size_t values.
5828 This makes a difference on win64, where ``printf`` needs "%Id" to display
5829 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00005831- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

5835 object; previously an int would be returned for small values. the __long__
5836 method is allowed to return either an int or a long, but the behaviour of

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005846 was correctly parsed but parsing of subsequent arguments failed.
5847
Vinay Sajip35e3b032008-09-01 14:33:59 +00005848- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005849 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5850 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5851 when given a tuple of classes as second argument, were looking up
5852 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5853 type object.

5950
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00005951- Issue #2975: When compiling several extension modules with Visual Studio 2008
5952 from the same python interpreter, some environment variables would grow
5953 without limit.
5954
Benjamin Peterson37346b22008-08-23 20:27:43 +00005955- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
5956 exploitation of poor argument checking.

5971 wrapper for warnings.catch_warnings() that makes it easier to check
5972 that expected warning messages are being reported.
5973

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005992What's New in Python 2.6 beta 3?
5993================================
5994
Barry Warsaw07a4a382008-08-21 01:15:08 +00005995*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005996
5997Core and Builtins
5998-----------------
5999
Guido van Rossumf8402962008-08-20 15:01:50 +00006000- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6001 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6002 extensions do not automatically benefit from the class attribute
6003 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6004 to their tp_flags field if they care. This is a backwards
6005 compatibility feature; in 3.0, all types will use the cache by
6006 default.
6007
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006008- Keyword arguments can now follow starred arguments. (``f(a, *args,
6009 keyword=23)`` is now valid syntax.)
6010
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006011- ctypes function pointers that are COM methods have a boolean True
6012 value again.
6013
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006014- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6015 by denying s# to parse objects that have a releasebuffer procedure,
6016 and introducing s*.
6017
Georg Brandl1e13ea92008-08-11 09:07:59 +00006018- Issue #3537: Fix an assertion failure when an empty but presized dict
6019 object was stored in the freelist.
6020
Mark Dickinsonb6467572008-08-04 21:30:09 +00006021- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6022 ValueError consistently across platforms.
6023
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006024- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6025 (64bit Unix, for example), unichr() would truncate its argument and return
6026 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6027
Neal Norwitze7d8be82008-07-31 17:17:14 +00006028- Apply security patches from Apple.
6029
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006030- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6031 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6032
Antoine Pitrou92f82162008-07-25 22:22:08 +00006033- Issue #1819: function calls with several named parameters are now on
6034 average 35% faster (as measured by pybench).
6035
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006036- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6037 the python debugger steps into a class statement: the free variables (local
6038 variables defined in an outer scope) would be deleted from the outer scope.
6039
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006040- Issue #2620: Overflow checking when allocating or reallocating memory
6041 was not always being done properly in some python types and extension
6042 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6043 all been updated to perform better checks and places in the code that
6044 would previously leak memory on the error path when such an allocation
6045 failed have been fixed.

6049
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00006050- Issue #3612: Added some missing basic types in ctypes.wintypes.
6051
Benjamin Petersone977ad42008-08-20 01:42:01 +00006052- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6053 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6054
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006055- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6056 version reported by these tools does not necessarily follow the python
6057 version numbering scheme, so the module is less strict when parsing it.
6058
Nick Coghlanf70385a2008-08-18 12:42:46 +00006059- Issue #2235: Added Py3k warnings for types which will become unhashable
6060 under the stricter __hash__ inheritance rules in 3.0. Several types
6061 which did not meet the rules for hash invariants and were already
6062 unhashable in 3.0 have now been explicitly flagged as unhashable in
6063 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6064 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6065
Brett Cannon88f801d2008-08-18 00:46:22 +00006066- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
6067 imported into the module but exposed as part of the module's API.
6068
Brett Cannon7b96f072008-08-18 00:41:11 +00006069- Remove an unneeded import of abc.ABCMeta from 'inspect'.
6070
Brett Cannon46225e72008-08-18 00:36:52 +00006071- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
6072
Brett Cannon25c9d6a2008-08-17 22:10:11 +00006073- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
6074
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006075- Issue #3575: Incremental decoder's decode function now takes bytearray
6076 by using 's*' instead of 't#'.
6077
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006078- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006079 fails unicode conversion on 2nd parameter. (windows only)
6080
Georg Brandl222e2082010-08-01 22:27:39 +00006081- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00006082 in a redirect.
6083
Brett Cannonabe423e2008-08-16 21:47:07 +00006084- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00006085 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00006086
Facundo Batistaeb90b782008-08-16 14:44:07 +00006087- Issue #2776: fixed small issue when handling an URL with double slash
6088 after a 302 response in the case of not going through a proxy.
6089
Antoine Pitroub90a8be2008-08-15 21:03:21 +00006090- Issue #2676: in the email package, content-type parsing was hanging on
6091 pathological input because of quadratic or exponential behaviour of a
6092 regular expression.
6093
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00006094- Issue #3476: binary buffered reading through the new "io" library is now
6095 thread-safe.
6096
Brett Cannonbf3157b2008-08-14 05:00:03 +00006097- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6098 since mimetools itself is deprecated. Because modules are cached, all
6099 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6100
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00006101- Issue #3134: shutil referenced undefined WindowsError symbol.
6102
Robert Schuppenies14646332008-08-10 11:01:53 +00006103- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
6104 menu entries were not deleted.
6105
Brett Cannon83e81842008-08-09 23:30:55 +00006106- Copied the implementation of reduce() to _functools.reduce() to have a
6107 version that did not raise a DeprecationWarning under -3.
6108
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00006109- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
6110 a MemoryError rather than silently stop the iteration.
6111
Guido van Rossum59ce9012008-08-09 14:55:34 +00006112- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
6113 to _sre.compile() will now be rejected. This should not affect anybody
6114 since the re.compile() function never generates invalid re-bytecode.
6115
Skip Montanaroa032bf42008-08-08 22:52:51 +00006116- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
6117 upon first access it can be automatically initialized from the csv file if
6118 it wasn't initialized during instantiation.
6119
Brett Cannon3aa2a492008-08-06 22:28:09 +00006120- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
6121 the reload() built-in has been removed.
6122
Brett Cannon7e30b672008-08-04 21:52:25 +00006123- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00006124 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

6132 raised an AttributeError.
6133
Benjamin Peterson01a24322008-07-28 23:35:27 +00006134- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00006135 asking for a specific length. This problem only affected files opened
6136 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00006137
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00006138- Issue #3449: Update decimal module to use most recent specification
6139 (v. 1.68) and tests (v. 2.58) from IBM.
6140
Georg Brandl222e2082010-08-01 22:27:39 +00006141- Issue #3437: Bug fix in robotparser parsing of Allow: lines.

6160
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00006161- Issue #3394: zipfile.writestr sets external attributes when passed a
6162 file name rather than a ZipInfo instance, so files are extracted with
6163 mode 0600 rather than 000 under Unix.
6164
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00006165- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
6166 argument in python 2.5, this broke code that subclassed Popen to include its
6167 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00006177- Issue #2235: the C API function PyObject_HashNotImplemented and its
6178 interaction with the tp_hash slot (added in 2.6b2) are now documented
6179
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00006180- Issue #643841: The language reference now provides more detailed
6181 coverage of the lookup process for special methods. The disclaimers
6182 regarding lack of coverage of new-style classes have also been
6183 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00006186What's New in Python 2.6 beta 2?
6187================================
6188
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006189*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00006191Core and Builtins
6192-----------------
6193
Georg Brandl3e483f62008-07-16 22:57:41 +00006194- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6195 its methods now allow for items objects that can be converted to
6196 an integer using operator.index().
6197
Mark Dickinson64b7e502008-07-16 09:40:03 +00006198- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6199 produced a ValueError instead of giving the correct float.
6200
Eric Smitha5fa5a22008-07-16 00:11:49 +00006201- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6202 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6203
Mark Dickinson7103aa42008-07-15 19:08:33 +00006204- Issue #3008: the float type has a new instance method 'float.hex'
6205 and a new class method 'float.fromhex' to convert floating-point
6206 numbers to and from hexadecimal strings, respectively.
6207
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006208- Issue #2235: __hash__ is once again inherited by default. To allow
6209 collections.Hashable to remain meaningful in the presence of the
6210 default hash implementation (object.__hash__), it is now possible
6211 to explicit block inheritance of hash by setting __hash__=None at
6212 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6213 level.
6214
Nick Coghlanb028f502008-07-13 14:52:36 +00006215- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6216 the parent module cannot be found while performing an absolute import.
6217 This means that an incorrectly defined __package__ attribute will
6218 now only prevent relative imports in that module rather than causing
6219 all imports from that module to fail.
6220
Nick Coghlan14ff9942008-07-08 14:21:42 +00006221- Issue #2517: Allow unicode messages in Exceptions again by correctly
6222 bypassing the instance dictionary when looking up __unicode__ on
6223 new-style classes.
6224
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00006225- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
6226 set to a custom object whose write() method happens to install
6227 another file in sys.stdout.

6231 another thread's dictionary.
6232
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006233- Issue #3004: Minor change to slice.indices(): the start and stop
6234 arguments are now treated identically, making the behaviour easier
6235 to describe and understand. For example, slice(None, -10,
6236 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6237 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6238 10, -1).

Georg Brandl5cc774e2008-06-11 20:28:06 +00006692 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00006693
6694 This is controlled by the configure argument ``--with-universal-archs``:
6695

6697
6698 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
6699
6700 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
6701
6702 This option should be used in combination with ``--enable-universalsdk=``.

6741 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00006742
Christian Heimese74c8f22008-04-19 02:23:57 +00006743- Added kill, terminate and send_signal(sig) to subprocess.Popen.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006754- Issue #1631171: Re-implement the 'warnings' module in C (the
6755 original Python code has been kept as backup). This will allow for
6756 using the 'warning's machinery in such places as the parser where
6757 use of pure Python code is not possible. Both the ``showarning()``
6758 and ``formatwarning()`` gain an optional 'line' argument which is
6759 not called by default for backwards-compatibility reasons. Setting
6760 ``warnings.showwarning()`` to an implementation that lacks support
6761 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006824- Issue #2550: The approach used by client/server code for obtaining
6825 ports to listen on in network-oriented tests has been refined in an
6826 effort to facilitate running multiple instances of the entire
6827 regression test suite in parallel without issue.
6828 test_support.bind_port() has been fixed such that it will always
6829 return a unique port -- which wasn't always the case with the
6830 previous implementation, especially if socket options had been set
6831 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6832 new implementation of bind_port() will actually raise an exception
6833 if it is passed an AF_INET/SOCK_STREAM socket with either the
6834 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6835 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6836 the socket it's been passed. This currently only applies to
6837 Windows. This option prevents any other sockets from binding to the
6838 host/port we've bound to, thus removing the possibility of the
6839 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6840 when a second SOCK_STREAM socket binds and accepts to a host/port
6841 that's already been bound by another socket. The optional preferred
6842 port parameter to bind_port() has been removed. Under no
6843 circumstances should tests be hard coding ports!
6844
6845 test_support.find_unused_port() has also been introduced, which will
6846 pass a temporary socket object to bind_port() in order to obtain an
6847 unused port. The temporary socket object is then closed and
6848 deleted, and the port is returned. This method should only be used
6849 for obtaining an unused port in order to pass to an external program
6850 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6851 a parameter to a server-oriented class that doesn't give you direct
6852 access to the underlying socket used.
6853
6854 Finally, test_support.HOST has been introduced, which should be used
6855 for the host argument of any relevant socket calls (i.e. bind and
6856 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006857
6858 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006859 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006860 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6861 test_asynchat and test_socket_ssl.
6862
Georg Brandl3ee81df2008-05-17 18:14:43 +00006863 It is now possible for multiple instances of the regression test
6864 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00007143- Added the future_builtins module, which contains hex() and oct().
7144 These are the PEP 3127 version of these functions, designed to be
7145 compatible with the hex() and oct() builtins from Python 3.0. They
7146 differ slightly in their output formats from the existing, unchanged
7147 Python 2.6 builtins. The expected usage of the future_builtins
7148 module is:
7149 from future_builtins import hex, oct
7150
Eric Smith7ef40bf2008-02-20 23:34:22 +00007151- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7152 exponents for exponents with absolute value < 100. Follows C99
7153 standard. This is a change on Windows, which would use 3 digits.
7154 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7155 so that any alterations it does to the resulting string will be
7156 available in stringlib/formatter.h (for float.__format__).
7157
Eric Smith5a3c1352008-02-19 13:21:56 +00007158- Implemented PEP 3101, Advanced String Formatting. This adds a new
7159 builtin format(); a format() method for str and unicode; a
7160 __format__() method to object, str, unicode, int, long, float, and
7161 datetime; the class string.Formatter; and the C API
7162 PyObject_Format().
7163
Georg Brandl3ee81df2008-05-17 18:14:43 +00007164- Fixed several potential crashes, all caused by specially crafted
7165 __del__ methods exploiting objects in temporarily inconsistent
7166 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00007167
Vinay Sajipb7edfc42008-04-02 21:10:23 +00007168- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00007169 prevent a possible crash: an Abstract Base Class would try to access
7170 a slot on a registered virtual subclass.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007175- Clear all free lists during a gc.collect() of the highest generation
7176 in order to allow pymalloc to free more arenas. Python may give back
7177 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007178
Georg Brandl3ee81df2008-05-17 18:14:43 +00007179- Issue #2045: Fix an infinite recursion triggered when printing a
7180 subclass of collections.defaultdict, if its default_factory is set
7181 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00007182
Christian Heimesf75dbef2008-02-08 00:11:31 +00007183- Fixed a minor memory leak in dictobject.c. The content of the free
7184 list was not freed on interpreter shutdown.
7185
Georg Brandl21e99f42010-03-07 15:23:59 +00007186- Limit free list of method and built-in function objects to 256

Christian Heimes6075a822008-02-06 12:44:34 +00007188
Georg Brandl3ee81df2008-05-17 18:14:43 +00007189- Patch #1953: Added ``sys._compact_freelists()`` and the C API
7190 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00007191 to compact the internal free lists of pre-allocted ints and floats.
7192
Georg Brandl3ee81df2008-05-17 18:14:43 +00007193- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
7194 calls. Python expected the return type int but the fork familie
7195 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00007196
Georg Brandl3ee81df2008-05-17 18:14:43 +00007197- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00007209- Patch #1473257: generator objects gain a gi_code attribute. This is
7210 the same object as the func_code attribute of the function that
7211 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007212
Georg Brandl3ee81df2008-05-17 18:14:43 +00007213- Issue #1920: "while 0" statements were completely removed by the
7214 compiler, even in the presence of an "else" clause, which is
7215 supposed to be run when the condition is false. Now the compiler
7216 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007217
Guido van Rossumeead05f2008-01-24 18:21:02 +00007218- A few crashers fixed: weakref_in_del.py (issue #1377858);

7220 borrowed_ref_[34].py (not in tracker).
7221
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00007222- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00007223 suppressed while an extension is loaded by calling SetErrorMode in

7225
Georg Brandl3ee81df2008-05-17 18:14:43 +00007226- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00007227 several extension methods and modules do not work without unicode
7228 support.
7229
Georg Brandl26543b12008-01-21 18:36:51 +00007230- Issue #1882: when compiling code from a string, encoding cookies in the
7231 second line of code were not always recognized correctly.
7232
Georg Brandl14404b62008-01-19 19:27:05 +00007233- Issue #1679: "0x" was taken as a valid integer literal.
7234
Georg Brandl6caad7d2008-01-26 14:19:22 +00007235- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00007236 added.
7237
Christian Heimesc94e2b52008-01-14 04:13:37 +00007238- sys.float_info / PyFloat_GetInfo: The floating point information
7239 object was converted from a dict to a specialized structseq object.
7240
Georg Brandl3ee81df2008-05-17 18:14:43 +00007241- Patch #1816: Added sys.flags structseq. It exposes the status of
7242 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007243
Georg Brandl3ee81df2008-05-17 18:14:43 +00007244- Objects/structseq.c: Implemented new structseq representation. The

Georg Brandl3ee81df2008-05-17 18:14:43 +00007305- Patch #1739468: Directories and zipfiles containing a __main__.py
7306 file can now be directly executed by passing their name to the
7307 interpreter. The directory/zipfile is automatically inserted as the
7308 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007310- Issue #1265: Fix a problem with sys.settrace, if the tracing
7311 function uses a generator expression when at the same time the
7312 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00007313
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00007314- sets and frozensets now have an isdisjoint() method.

7319
Georg Brandl21e99f42010-03-07 15:23:59 +00007320- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007321 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7322 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007323
Georg Brandl3ee81df2008-05-17 18:14:43 +00007324- Issue #1686386: Tuple's tp_repr did not take into account the
7325 possibility of having a self-referential tuple, which is possible
7326 from C code. Nor did object's tp_str consider that a type's tp_str
7327 could do something that could lead to an inifinite recursion.
7328 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7329 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007330
Georg Brandl3ee81df2008-05-17 18:14:43 +00007331- Issue #1164: It was possible to trigger deadlock when using the
7332 'print' statement to write to a file since the GIL was not released
7333 as needed. Now PyObject_Print() does the right thing along with
7334 various tp_print implementations of the built-in types and those in
7335 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007336
Georg Brandl3ee81df2008-05-17 18:14:43 +00007337- Issue #1147: Exceptions were directly allowing string exceptions in

7339 allowed.

Brett Cannona0c05512007-09-10 21:38:27 +00007343
Brett Cannon1e534b52007-09-07 04:18:30 +00007344- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007345 PyObject_Call() never calling back out to Python code to trigger
7346 recursion depth updates/checks. Required the creation of a static
7347 RuntimeError instance in case normalizing an exception put the
7348 recursion check value past its limit. Fixes crashers
7349 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00007350

Neal Norwitz0ac60192007-05-27 04:08:54 +00007364- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00007365 __*__ attributes. (Some already existed, e.g., __doc__ and
7366 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00007367
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00007368- Add -3 option to the interpreter to warn about features that are
7369 deprecated and will be changed/removed in Python 3.0.
7370
Georg Brandl2134e752007-05-21 20:34:16 +00007371- Patch #1686487: you can now pass any mapping after '**' in function
7372 calls.
7373
Collin Winter62903052007-05-18 23:11:24 +00007374- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00007375 "except E as target:". This is to provide forwards compatibility
7376 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00007383- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00007384 setting a plain string, ie don't expand to single letter identifiers.
7385
Raymond Hettinger13936692007-04-11 18:40:58 +00007386- Request #1191699: Slices can now be pickled.
7387
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00007388- Request #1193128: str.translate() now allows a None argument for
7389 translations that only remove characters without re-mapping the
7390 remaining characters.
7391
Georg Brandl5cb76c12007-03-21 09:00:39 +00007392- Patch #1682205: a TypeError while unpacking an iterable is no longer
7393 masked by a generic one with the message "unpack non-sequence".
7394
Neal Norwitzaa754b72007-03-21 06:39:48 +00007395- Remove unused file Python/fmod.c.
7396
Guido van Rossum143b5642007-03-23 04:58:42 +00007397- Bug #1683368: The object.__init__() and object.__new__() methods are
7398 now stricter in rejecting excess arguments. The only time when
7399 either allows excess arguments is when it is not overridden and the
7400 other one is. For backwards compatibility, when both are
7401 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007402 warning later). Also, type.__init__() insists on the same signature
7403 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00007404
Georg Brandl3ee81df2008-05-17 18:14:43 +00007405- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7406 object to complex using its __complex__() method before falling back
7407 to the __float__() method. Therefore, the functions in the cmath
7408 module now can operate on objects that define a __complex__()
7409 method.
Georg Brandl2b869942007-03-17 16:08:45 +00007410
Georg Brandl3ee81df2008-05-17 18:14:43 +00007411- Patch #1623563: allow __class__ assignment for classes with
7412 __slots__. The old and the new class are still required to have the
7413 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00007414

7419 ``object.__reduce_ex__()`` is called with an object that is faking
7420 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00007421
Georg Brandl3ee81df2008-05-17 18:14:43 +00007422- Patch #1680015: Don't modify __slots__ tuple if it contains an

7426
Georg Brandl7b9c5552007-03-12 14:30:05 +00007427- Bug #1678647: write a newline after printing an exception in any
7428 case, even when converting the value to a string failed.
7429
Georg Brandl871f1bc2007-03-12 13:17:36 +00007430- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007431 its argument, if it exists. If not, it will work like before. This
7432 allows customizing the output of dir() in the presence of a
7433 __getattr__().

Collin Winter276887b2007-03-12 16:11:39 +00007435- Patch #922167: Python no longer segfaults when faced with infinitely
7436 self-recursive reload() calls (as reported by bug #742342).
7437
Georg Brandl3ee81df2008-05-17 18:14:43 +00007438- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00007441- Patch #1491866: change the complex() constructor to allow
7442 parthensized forms. This means complex(repr(x)) now works instead of
7443 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00007444
Georg Brandlaa2321b2007-03-07 00:40:28 +00007445- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007446 makes the filenames the warning module prints much more sensible
7447 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00007448

7450 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00007451 variable is given, but break into the interactive interpreter just
7452 like on other exceptions or normal program exit.

Georg Brandl098cd692007-03-06 12:17:50 +00007459
Georg Brandl0fca97a2007-03-05 22:28:08 +00007460- Patch #1674228: when assigning a slice (old-style), check for the
7461 sq_ass_slice instead of the sq_slice slot.
7462
Georg Brandl3ee81df2008-05-17 18:14:43 +00007463- When printing an unraisable error, don't print exceptions. before
7464 the name. This duplicates the behavior whening normally printing
7465 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008375- Issue #829951: In the smtplib module, SMTP.starttls() now complies
8376 with RFC 3207 and forgets any knowledge obtained from the server not
8377 obtained from the TLS negotiation itself. Patch contributed by Bill
8378 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00008379
Georg Brandl3ee81df2008-05-17 18:14:43 +00008380- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00008381 that the SMTP.starttls() caller no longer needs to call ehlo()
8382 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00008383 does not claim to support starttls. Adds the
8384 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +00008439- itertools.chain() now has an alternate constructor,

8465 complex, tuple, list, dict, set, and frozenset. Formerly, it would
8466 silently miscode subclasses of those types. Now, it raises a
8467 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00008468

Georg Brandl3ee81df2008-05-17 18:14:43 +00008483 time so that opening a database previously created with the DB_DUP
8484 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8485 opens. Specifically: dictionary assignment to a DB object will
8486 replace all values for a given key when the database allows
8487 duplicate values. DB users should use DB.put(k, v) when they want
8488 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00008489

8495 characters with ASCII value less than 32. Also, it correctly quotes
8496 dots only if they occur on a single line, as opposed to the previous
8497 behavior of quoting dots if they are the second character of any
8498 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00008499

8760
Guido van Rossum7c862f82007-12-13 20:50:10 +00008761- Bug #1608: use -fwrapv when GCC supports it. This is important,

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00008767- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00008768 periodic threadstate and signal checking in tight loops. By
8769 default, this option is turned-off. It should only be enabled in
8770 debugged, performance critical applications.

8821-----
8822
Georg Brandl3ee81df2008-05-17 18:14:43 +00008823- Unified naming convention for free lists and their limits. All free
8824 lists in Object/ are named ``free_list``, the counter ``numfree``
8825 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
8826 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00008827
Georg Brandl3ee81df2008-05-17 18:14:43 +00008828- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
8829 to ``PyTuple_SetItem``, it can be used to populate a brand new
8830 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00008831

8839
8840- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
8841 ``PyFloat_GetInfo()`` to the float API.
8842
Georg Brandl3ee81df2008-05-17 18:14:43 +00008843- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
8844 of w# format code incorrectly truncated the length to an int, even
8845 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
8846 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00008847
Georg Brandl3ee81df2008-05-17 18:14:43 +00008848- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

8866- Fix some leftovers from the conversion from int to Py_ssize_t
8867 (relevant to strings and sequences of more than 2**31 items).
8868
8869- Make _PyGILState_NoteThreadState() static, it was not used anywhere
8870 outside of pystate.c and should not be necessary.
8871
Georg Brandl3ee81df2008-05-17 18:14:43 +00008872- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
8873 absolute imports. In earlier versions they might have used relative
8874 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00008875
Georg Brandl3ee81df2008-05-17 18:14:43 +00008876- Added case insensitive comparison methods ``PyOS_stricmp(char*,
8877 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00008878
Georg Brandl3ee81df2008-05-17 18:14:43 +00008879- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

8887 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
8888 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
8889 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00008890

Georg Brandl3ee81df2008-05-17 18:14:43 +00008904- Removed the macfs module. It had been deprecated since Python 2.5.
8905 This lead to the deprecation of macostools.touched() as it relied
8906 solely on macfs and was a no-op under OS X.
