105
Ned Deily87e82bb2011-06-28 19:52:59 -0700106- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
107 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
108 interpreter process. This could cause failures in non-Distutils subprocesses
109 and was unreliable since tests or user programs could modify the interpreter
110 environment after Distutils set it. Instead, have Distutils set the the
111 deployment target only in the environment of each build subprocess. It is
112 still possible to globally override the default by setting
113 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
114 greater or equal to the default value, the value with which the interpreter
115 was built.
116
Raymond Hettinger2c316a32011-06-25 17:14:53 +0200117- Issue #11802: The cache in filecmp now has a maximum size of 100 so that

121 Kitada.
122
R David Murrayf1138bb2011-06-17 22:23:04 -0400123- Issue #11700: mailbox proxy object close methods can now be called multiple
124 times without error, and _ProxyFile now closes the wrapped file.
125
Victor Stinnerc74a6ba2011-06-17 14:06:27 +0200126- Issue #12133: AbstractHTTPHandler.do_open() of urllib.request closes the HTTP
127 connection if its getresponse() method fails with a socket error. Patch
128 written by Ezio Melotti.
129
Benjamin Peterson0eb4ac42011-06-11 15:53:11 -0500130- Issue #9284: Allow inspect.findsource() to find the source of doctest
131 functions.
132

142
Barry Warsawc5643282011-07-19 17:06:30 -0400143- sys.setcheckinterval() now updates the current ticker count as well as
144 updating the check interval, so if the user decreases the check interval,
145 the ticker doesn't have to wind down to zero from the old starting point
146 before the new interval takes effect. And if the user increases the
147 interval, it makes sure the new limit takes effect right away rather have an
148 early task switch before recognizing the new interval.
Raymond Hettinger19b851d2011-06-01 18:21:42 -0700149
Victor Stinner776e69b2011-06-01 01:03:00 +0200150- Issue #12085: Fix an attribute error in subprocess.Popen destructor if the

Raymond Hettinger20397532010-09-12 02:11:45 +00001003- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
1004 This prevents user-created self-referencing ordered dictionaries from
1005 becoming permanently uncollectable GC garbage. The downside is that
1006 removing __del__ means that the internal doubly-linked list has to wait for
1007 GC collection rather than freeing memory immediately when the refcnt drops
1008 to zero.
1009
Raymond Hettingerffd2a422010-09-10 10:47:22 +00001010- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently

1015 would swallow the exception and raise a new one, making it impossible
1016 to fetch the original errno, or to filter timeout errors. Now the
1017 original error is re-raised.
1018
Antoine Pitrouf4f61712010-09-07 16:34:47 +00001019- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,

1038
R. David Murray7c4bf552010-08-25 01:45:57 +00001039- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
1040 character years even if the message contains RFC822 two character years.
1041
Daniel Stutzbach91287322010-08-24 21:09:30 +00001042- Issue #8750: Fixed MutableSet's methods to correctly handle

1055
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00001056- Issue #9617: Signals received during a low-level write operation aren't
1057 ignored by the buffered IO layer anymore.
1058
Benjamin Peterson52c36052010-08-21 03:03:22 +00001059- Issue #2521: Use weakrefs on for caching in the abc module, so that classes

1061
Raymond Hettingera54b2da2010-08-17 19:03:06 +00001062- Issue #9626: the view methods for collections.OrderedDict() were returning

1071 and a BadZipfile error is raised if it doesn't match (as used to be the
1072 case in Python 2.5 and earlier).
1073
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00001074- Issue #9550: a BufferedReader could issue an additional read when the
1075 original read request had been satisfied, which could block indefinitely
1076 when the underlying raw IO channel was e.g. a socket. Report and original
1077 patch by Jason V. Miller.
1078
Fred Drake0a1fa0e2010-08-10 13:09:54 +00001079- Issue #9551: Don't raise TypeError when setting the value to None for

1098 This is how it is supposed to work, wget and curl do the same. Previous

Philip Jenveyaebbaeb2010-04-06 23:24:45 +00001853- Issue #7301: Add environment variable $PYTHONWARNINGS.
1854
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00001855- Issue #8329: Don't return the same lists from select.select when no fds are
1856 changed.
1857
Georg Brandlfee0f442010-05-22 21:26:21 +00001858- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00001859 on 64-bit machines. The shift count for either left or right shift is
1860 permitted to be up to sys.maxsize.

Georg Brandlfee0f442010-05-22 21:26:21 +00001868- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1869 with a non-empty format string. This is an effort to future-proof user
1870 code. If a derived class does not currently implement __format__ but later
1871 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00001872 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00001873 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00001906- Issue #8257: The Decimal construct now accepts a float instance directly,

Georg Brandlfee0f442010-05-22 21:26:21 +00001923- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1924 InvalidOperation instead of returning False. (Comparisons involving a quiet
1925 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1926 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00001927
Georg Brandlfee0f442010-05-22 21:26:21 +00001928- Issue #2531: Comparison operations between floats and Decimal instances now
1929 return a result based on the numeric values of the operands; previously they
1930 returned an arbitrary result based on the relative ordering of id(float) and
1931 id(Decimal).

Barry Warsawf7f2d6f2010-03-31 21:07:16 +00001933- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00001934 argument `-` which tells it to read files to compile from stdin. Each line is
1935 read on demand and the named file is compiled immediately. (Original patch by

Georg Brandlfee0f442010-05-22 21:26:21 +00001943 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/

Georg Brandlfee0f442010-05-22 21:26:21 +00001945- Comparisons using one of <, <=, >, >= between a complex instance and a
1946 Fractions instance now raise TypeError instead of returning True/False. This
1947 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1948 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00002305- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
2306 and add the additional members returned in an OSVERSIONINFOEX structure. The
2307 new members are service_pack_major, service_pack_minor, suite_mask, and

Georg Brandlba83f822010-03-14 09:50:54 +00002310- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
2311 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
2312 returning NULL. The macro now returns a statically allocated empty string
2313 instead.

Georg Brandlba83f822010-03-14 09:50:54 +00002359 specified, rather than fall through to AF_PACKET (in the ``socket`` module).

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002365- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00002366 file position when calling `truncate()`. It would previously change the file
2367 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002368 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
2369

2371 class used to represent files stored inside an archive. The new
2372 implementation is significantly faster and can be wrapped in a
2373 ``io.BufferedReader`` object for more speedups. It also solves an issue
2374 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00002385- Issue #7748: Since unicode values are supported for some metadata options in
2386 Distutils, the DistributionMetadata get_* methods will now return an utf-8
2387 encoded string for them. This ensures that the upload and register commands
2388 send the correct values to PyPI without any error.

2463-----------------
2464
Georg Brandlba83f822010-03-14 09:50:54 +00002465- The ``__complex__()`` method is now looked up on the class of instances to
2466 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00002467
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00002468- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
2469 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
2470
Mark Dickinson1b34d252010-01-01 17:27:30 +00002471- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00002472 DeprecationWarning when passed a float argument where an integer was expected.
2473 These functions and methods now raise TypeError instead. The majority of the
2474 effects of this change are in the extension modules, but some core functions
2475 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2476 and many unicode/str methods.
Mark Dickinson1b34d252010-01-01 17:27:30 +00002477

Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +00002486- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
2487 used to drop the time part of the result.
2488
Georg Brandlba83f822010-03-14 09:50:54 +00002489- Issue #1811: Improve accuracy and cross-platform consistency for true division
2490 of integers: the result of a/b is now correctly rounded for ints a and b (at
2491 least on IEEE 754 platforms), and in particular does not depend on the
2492 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +00002493
Georg Brandlba83f822010-03-14 09:50:54 +00002494- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
2495 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
2496 in the subclass.
Ezio Melottif84caf42009-12-24 22:25:17 +00002497

Ronald Oussoren92919a62009-12-24 13:30:58 +00002499 executables on OSX.
2500
Georg Brandlba83f822010-03-14 09:50:54 +00002501 These executables now work properly with the arch(1) command: ``arch -ppc
2502 python`` will start a universal binary version of python in PPC mode (unlike
2503 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +00002504
Georg Brandlba83f822010-03-14 09:50:54 +00002505- Issue #1680159: Unicode coercion during an 'in' operation no longer masks the
2506 underlying error when the coercion fails for the left hand operand.

2518 allowing for a maximum number of tasks within the pool to be completed by the
2519 worker before that worker is terminated, and a new one created to replace it.

Antoine Pitrou80157252010-01-08 19:20:17 +00002525- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
Georg Brandlba83f822010-03-14 09:50:54 +00002526 renaming of `cPickle` to `pickle`. The warning was annoying since there's no
2527 alternative to cPickle if you care about performance. Patch by Florent

Benjamin Petersonddd392c2009-12-13 19:19:07 +00002562- Issue #7349: Make methods of file objects in the io module accept None as an
2563 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
2564 the same as passing no argument.
2565
Georg Brandlba83f822010-03-14 09:50:54 +00002566- Issue #7348: ``StringIO.StringIO.readline(-1)`` now acts as if it got no

2589 ``PyArg_ParseTupleAndKeywords()``, ``PyArg_VaParse()``,
2590 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept
2591 float arguments for integer format codes (other than 'L'): previously an

Georg Brandlba83f822010-03-14 09:50:54 +00002659- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2660 decimal string that's guaranteed to round back to x under correct rounding
2661 (with round-half-to-even rounding mode). Previously it gave a string based on
2662 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2663 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2664 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002665
Georg Brandlba83f822010-03-14 09:50:54 +00002666- Issue #7117: On almost all platforms: float-to-string and string-to-float
2667 conversions within Python are now correctly rounded. Places these conversions
2668 occur include: str for floats and complex numbers; the float and complex
2669 constructors; old-style and new-style numeric formatting; serialization and
2670 deserialization of floats and complex numbers using marshal, pickle and json;
2671 parsing of float and imaginary literals in Python code; Decimal-to-float
2672 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002673
Georg Brandlba83f822010-03-14 09:50:54 +00002674 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2675 providing correctly-rounded strtod and dtoa C functions. This code is
2676 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2677 the C compiler. There may be a small number of platforms on which correct
2678 operation of this code cannot be guaranteed, so the code is not used: notably,
2679 this applies to platforms where the C double format is not IEEE 754 binary64,
2680 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2681 and Python's configure script is unable to determine how to change the FPU
2682 precision. On these platforms conversions use the platform strtod and dtoa,
2683 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002684
Georg Brandlba83f822010-03-14 09:50:54 +00002685- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2686 uses the correctly-rounded string <-> float conversions described above (when
2687 available), and so produces correctly rounded results that will display nicely
2688 under the float repr. There are two related small changes: (1) round now
2689 accepts any class with an ``__index__()`` method for its second argument (but
2690 no longer accepts floats for the second argument), and (2) an excessively
2691 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2692 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00002910 untrackable objects are not tracked by the garbage collector. This can reduce
2911 the size of collections and therefore the garbage collection overhead on
2912 long-running programs, depending on their particular use of datatypes.

Georg Brandlba83f822010-03-14 09:50:54 +00002918- Issue #4258: Make it possible to use base 2**30 instead of base 2**15 for the
2919 internal representation of integers, for performance reasons. Base 2**30 is
2920 enabled by default on 64-bit machines. Add --enable-big-digits option to
2921 configure, which overrides the default. Add sys.long_info structseq to
2922 provide information about the internal format.

2953
Georg Brandl29c6a282009-04-05 20:23:13 +00002954- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +00002955 were suppressing all exceptions. These include list(), filter(), map(),

2957
Benjamin Peterson596d3062009-01-19 15:42:23 +00002958- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os

Georg Brandlba83f822010-03-14 09:50:54 +00002966- Issue #4935: The overflow checking code in the expandtabs() method common to
2967 str, bytes and bytearray could be optimized away by the compiler, letting the
2968 interpreter segfault instead of raising an error.

2978 collecting the oldest generation) so that allocating lots of objects without
2979 destroying them does not show quadratic performance. Based on a proposal by

2984
Georg Brandlba83f822010-03-14 09:50:54 +00002985- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
2986 existing .py counterpart, override the co_filename attributes of all code
2987 objects if the original filename is obsolete (which can happen if the file has
2988 been renamed, moved, or if it is accessed through different paths). Patch by

3029 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
3030 instances. On a typical machine this saves 3 bytes of memory (on average) per

3042
Georg Brandlba83f822010-03-14 09:50:54 +00003043- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
3044 file objects with closefd=False. The file descriptor is still kept open but
3045 the file object behaves like a closed file. The ``FileIO`` object also got a
3046 new readonly attribute ``closefd``.

3065
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00003066- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00003067 because it is a reserved word in 3.x.

Georg Brandlba83f822010-03-14 09:50:54 +00003069- On windows, ``os.chdir()`` given unicode was not working if
3070 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
3071 this code path is really executed because I cannot move to such directory on
3072 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00003074- Issue #4069: When ``set.remove(element)`` is used with a set element, the
3075 element is temporarily replaced with an equivalent frozenset. But the
3076 eventual KeyError would always report the empty ``frozenset()`` as the missing
3077 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00003097- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
3098 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
3099 step. This avoids problems with counting UTF-8 bytes that ignores the effect
3100 of using the replace error handler in PyUnicode_DecodeUTF8().
3101
Walter Dörwald726ba8e2009-05-06 14:32:35 +00003102- Issue #3739: The unicode-internal encoder now reports the number of characters

Georg Brandlba83f822010-03-14 09:50:54 +00003105- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

3107 gives improved memory leak detection when running under Valgrind, while taking
3108 advantage of pymalloc at other times.

4274 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
4275 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
4276 neither __int__ nor __long__, TypeError used to be raised (with a
4277 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
4278 struct.error in other cases.

4281 argument with an __int__ method can be packed, but use of this feature
4282 triggers a DeprecationWarning.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004475- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4476 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4477 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4478 ``printf`` function, whereas PyString_FromFormat has an independent
4479 implementation and uses "%zd" on all platforms for size_t values.

Brett Cannon1eaf0742008-09-02 01:25:16 +00004576 warnings.catch_warnings() along with some API cleanup. Expanding the tests
4577 for catch_warnings() also led to an improvement in the raising of a
4578 DeprecationWarning related to warnings.warn_explicit().
4579

4602
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00004603- Issue #2975: When compiling several extension modules with Visual Studio 2008
4604 from the same python interpreter, some environment variables would grow
4605 without limit.
4606
Benjamin Peterson37346b22008-08-23 20:27:43 +00004607- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004644What's New in Python 2.6 beta 3?
4645================================
4646
Barry Warsaw07a4a382008-08-21 01:15:08 +00004647*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004648
4649Core and Builtins
4650-----------------
4651
Guido van Rossumf8402962008-08-20 15:01:50 +00004652- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4653 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4654 extensions do not automatically benefit from the class attribute
4655 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4656 to their tp_flags field if they care. This is a backwards
4657 compatibility feature; in 3.0, all types will use the cache by
4658 default.
4659
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004660- Keyword arguments can now follow starred arguments. (``f(a, *args,
4661 keyword=23)`` is now valid syntax.)
4662
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004663- ctypes function pointers that are COM methods have a boolean True
4664 value again.
4665
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004666- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4667 by denying s# to parse objects that have a releasebuffer procedure,
4668 and introducing s*.
4669
Georg Brandl1e13ea92008-08-11 09:07:59 +00004670- Issue #3537: Fix an assertion failure when an empty but presized dict
4671 object was stored in the freelist.
4672
Mark Dickinsonb6467572008-08-04 21:30:09 +00004673- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4674 ValueError consistently across platforms.
4675
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004676- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4677 (64bit Unix, for example), unichr() would truncate its argument and return
4678 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4679
Neal Norwitze7d8be82008-07-31 17:17:14 +00004680- Apply security patches from Apple.
4681
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004682- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4683 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4684
Antoine Pitrou92f82162008-07-25 22:22:08 +00004685- Issue #1819: function calls with several named parameters are now on
4686 average 35% faster (as measured by pybench).
4687
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004688- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4689 the python debugger steps into a class statement: the free variables (local
4690 variables defined in an outer scope) would be deleted from the outer scope.
4691
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004692- Issue #2620: Overflow checking when allocating or reallocating memory
4693 was not always being done properly in some python types and extension
4694 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4695 all been updated to perform better checks and places in the code that
4696 would previously leak memory on the error path when such an allocation
4697 failed have been fixed.

4700-------
4701

4703
Benjamin Petersone977ad42008-08-20 01:42:01 +00004704- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4705 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4706
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004707- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4708 version reported by these tools does not necessarily follow the python
4709 version numbering scheme, so the module is less strict when parsing it.
4710
Nick Coghlanf70385a2008-08-18 12:42:46 +00004711- Issue #2235: Added Py3k warnings for types which will become unhashable
4712 under the stricter __hash__ inheritance rules in 3.0. Several types
4713 which did not meet the rules for hash invariants and were already
4714 unhashable in 3.0 have now been explicitly flagged as unhashable in
4715 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4716 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4717
Brett Cannon88f801d2008-08-18 00:46:22 +00004718- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

4726
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004727- Issue #3575: Incremental decoder's decode function now takes bytearray
4728 by using 's*' instead of 't#'.
4729
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004730- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004731 fails unicode conversion on 2nd parameter. (windows only)
4732
Georg Brandl222e2082010-08-01 22:27:39 +00004733- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004734 in a redirect.
4735

Brett Cannon721b1452008-08-16 22:00:27 +00004737 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004738
Facundo Batistaeb90b782008-08-16 14:44:07 +00004739- Issue #2776: fixed small issue when handling an URL with double slash
4740 after a 302 response in the case of not going through a proxy.
4741
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004742- Issue #2676: in the email package, content-type parsing was hanging on
4743 pathological input because of quadratic or exponential behaviour of a
4744 regular expression.
4745
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004746- Issue #3476: binary buffered reading through the new "io" library is now
4747 thread-safe.
4748
Brett Cannonbf3157b2008-08-14 05:00:03 +00004749- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4750 since mimetools itself is deprecated. Because modules are cached, all
4751 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4752
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004753- Issue #3134: shutil referenced undefined WindowsError symbol.
4754
Robert Schuppenies14646332008-08-10 11:01:53 +00004755- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4756 menu entries were not deleted.
4757
Brett Cannon83e81842008-08-09 23:30:55 +00004758- Copied the implementation of reduce() to _functools.reduce() to have a
4759 version that did not raise a DeprecationWarning under -3.
4760
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004761- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4762 a MemoryError rather than silently stop the iteration.
4763
Guido van Rossum59ce9012008-08-09 14:55:34 +00004764- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4765 to _sre.compile() will now be rejected. This should not affect anybody
4766 since the re.compile() function never generates invalid re-bytecode.
4767
Skip Montanaroa032bf42008-08-08 22:52:51 +00004768- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4769 upon first access it can be automatically initialized from the csv file if
4770 it wasn't initialized during instantiation.
4771
Brett Cannon3aa2a492008-08-06 22:28:09 +00004772- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4773 the reload() built-in has been removed.
4774
Brett Cannon7e30b672008-08-04 21:52:25 +00004775- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00004776 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00004787 asking for a specific length. This problem only affected files opened
4788 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00004789

4834 regarding lack of coverage of new-style classes have also been
4835 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00004838What's New in Python 2.6 beta 2?
4839================================
4840
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004841*Release date: 17-Jul-2008*
4842
Raymond Hettingere3ae6552008-06-20 04:18:15 +00004843Core and Builtins
4844-----------------
4845
Georg Brandl3e483f62008-07-16 22:57:41 +00004846- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4847 its methods now allow for items objects that can be converted to
4848 an integer using operator.index().
4849
Mark Dickinson64b7e502008-07-16 09:40:03 +00004850- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4851 produced a ValueError instead of giving the correct float.
4852
Eric Smitha5fa5a22008-07-16 00:11:49 +00004853- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4854 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4855
Mark Dickinson7103aa42008-07-15 19:08:33 +00004856- Issue #3008: the float type has a new instance method 'float.hex'
4857 and a new class method 'float.fromhex' to convert floating-point
4858 numbers to and from hexadecimal strings, respectively.
4859
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004860- Issue #2235: __hash__ is once again inherited by default. To allow
4861 collections.Hashable to remain meaningful in the presence of the
4862 default hash implementation (object.__hash__), it is now possible
4863 to explicit block inheritance of hash by setting __hash__=None at
4864 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4865 level.
4866
Nick Coghlanb028f502008-07-13 14:52:36 +00004867- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4868 the parent module cannot be found while performing an absolute import.
4869 This means that an incorrectly defined __package__ attribute will
4870 now only prevent relative imports in that module rather than causing
4871 all imports from that module to fail.
4872
Nick Coghlan14ff9942008-07-08 14:21:42 +00004873- Issue #2517: Allow unicode messages in Exceptions again by correctly
4874 bypassing the instance dictionary when looking up __unicode__ on
4875 new-style classes.
4876
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00004877- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
4878 set to a custom object whose write() method happens to install
4879 another file in sys.stdout.
4880
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00004881- Issue #3088: Corrected a race condition in classes derived from
4882 threading.local: the first member set by a thread could be saved in
4883 another thread's dictionary.
4884
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004885- Issue #3004: Minor change to slice.indices(): the start and stop
4886 arguments are now treated identically, making the behaviour easier
4887 to describe and understand. For example, slice(None, -10,
4888 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4889 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4890 10, -1).
4891
Georg Brandl278fc502008-07-19 12:46:12 +00004892- Issue #3219: Calling a function with repeated keyword arguments,
4893 f(a=2, a=23), would not cause a syntax error. This was a regression
4894 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00004895
Georg Brandl278fc502008-07-19 12:46:12 +00004896- Issue #2862: Make int and float freelist management consistent with
4897 other freelists. Changes their CompactFreeList apis into
4898 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00004899
Brett Cannon8bb8fa52008-07-02 01:57:08 +00004900Library
4901-------
4902
Thomas Heller57adf222008-08-14 19:10:48 +00004903- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
4904 api functions without holding the GIL, which could lead to a fatal
4905 error when they failed.
4906
Martin v. Löwisaabf4042008-08-02 07:20:25 +00004907- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.
4908
Jesse Noller7fb96402008-07-17 21:01:05 +00004909- Issue #3395: fix reference in test_multiprocessing to old debugInfo method

4914
Jesse Noller13e9d582008-07-16 14:32:36 +00004915- Issue #3125: Remove copy_reg in multiprocessing and replace it with
4916 ForkingPickler.register() to resolve conflict with ctypes.
4917
Vinay Sajip51e65192008-07-18 09:01:10 +00004918- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00004919
Thomas Heller880f5292008-07-15 19:39:38 +00004920- Issue #3313: Fixed a crash when a failed dlopen() call does not set
4921 a valid dlerror() message.
4922
Thomas Heller2bad6572008-07-15 17:19:50 +00004923- Issue #3258: Fixed a crash when a ctypes POINTER type to an
4924 incomplete structure was created.
4925
Brett Cannon3d0b9f02008-07-13 01:15:07 +00004926- Issue #3339: dummy_thread.acquire() should not return None.
4927
Raymond Hettingerb01713e2008-07-10 14:34:57 +00004928- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
4929
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004930- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00004931
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004932- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
4933 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004934 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004935 content-length. The problem had been corrected in the 2.4 branch, but never
4936 merged into trunk.
4937
Georg Brandle78fbcc2008-07-05 10:13:36 +00004938- Issue #2663: add filtering capability to shutil.copytree().
4939

4941
4942- Issue #1526: Allow more than 64k files to be added to Zip64 file.
4943
4944- Issue #1746: Correct handling of zipfile archive comments (previously
4945 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00004946 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00004947
Vinay Sajip51e65192008-07-18 09:01:10 +00004948- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004949 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00004950
Nick Coghlanc060b0e2008-07-02 13:09:19 +00004951- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
4952 handling is now the same as that of other special attributes like __name__).
4953
Brett Cannon8bb8fa52008-07-02 01:57:08 +00004954- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
4955 removal in Python 3.0 in favor of urllib2.urlopen().

4963
Gregory P. Smithc4691ec2008-07-07 05:09:12 +00004964- Issue #3094: httplib.HTTPSConnection Host: headers no longer include the
4965 redundant ":443" port number designation when the connection is using the

Georg Brandl3ee81df2008-05-17 18:14:43 +00005406- Issue #1631171: Re-implement the 'warnings' module in C (the
5407 original Python code has been kept as backup). This will allow for
5408 using the 'warning's machinery in such places as the parser where
5409 use of pure Python code is not possible. Both the ``showarning()``
5410 and ``formatwarning()`` gain an optional 'line' argument which is
5411 not called by default for backwards-compatibility reasons. Setting
5412 ``warnings.showwarning()`` to an implementation that lacks support
5413 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005476- Issue #2550: The approach used by client/server code for obtaining
5477 ports to listen on in network-oriented tests has been refined in an
5478 effort to facilitate running multiple instances of the entire
5479 regression test suite in parallel without issue.
5480 test_support.bind_port() has been fixed such that it will always
5481 return a unique port -- which wasn't always the case with the
5482 previous implementation, especially if socket options had been set
5483 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5484 new implementation of bind_port() will actually raise an exception
5485 if it is passed an AF_INET/SOCK_STREAM socket with either the
5486 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5487 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5488 the socket it's been passed. This currently only applies to
5489 Windows. This option prevents any other sockets from binding to the
5490 host/port we've bound to, thus removing the possibility of the
5491 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5492 when a second SOCK_STREAM socket binds and accepts to a host/port
5493 that's already been bound by another socket. The optional preferred
5494 port parameter to bind_port() has been removed. Under no
5495 circumstances should tests be hard coding ports!
5496
5497 test_support.find_unused_port() has also been introduced, which will
5498 pass a temporary socket object to bind_port() in order to obtain an
5499 unused port. The temporary socket object is then closed and
5500 deleted, and the port is returned. This method should only be used
5501 for obtaining an unused port in order to pass to an external program
5502 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5503 a parameter to a server-oriented class that doesn't give you direct
5504 access to the underlying socket used.
5505
5506 Finally, test_support.HOST has been introduced, which should be used
5507 for the host argument of any relevant socket calls (i.e. bind and
5508 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005509
5510 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005511 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005512 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5513 test_asynchat and test_socket_ssl.
5514
Georg Brandl3ee81df2008-05-17 18:14:43 +00005515 It is now possible for multiple instances of the regression test
5516 suite to run in parallel without issue.

5672 processor information on Windows XP and later. As a result,
Marc-André Lemburga1867752008-03-20 18:08:00 +00005673 platform.machine() and platform.processor() will report this
5674 information as well.

Eric Smitha73fbe72008-02-23 03:09:44 +00005795- Added the future_builtins module, which contains hex() and oct().
5796 These are the PEP 3127 version of these functions, designed to be
5797 compatible with the hex() and oct() builtins from Python 3.0. They
5798 differ slightly in their output formats from the existing, unchanged
5799 Python 2.6 builtins. The expected usage of the future_builtins
5800 module is:
5801 from future_builtins import hex, oct
5802
Eric Smith7ef40bf2008-02-20 23:34:22 +00005803- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5804 exponents for exponents with absolute value < 100. Follows C99
5805 standard. This is a change on Windows, which would use 3 digits.
5806 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5807 so that any alterations it does to the resulting string will be
5808 available in stringlib/formatter.h (for float.__format__).
5809
Eric Smith5a3c1352008-02-19 13:21:56 +00005810- Implemented PEP 3101, Advanced String Formatting. This adds a new
5811 builtin format(); a format() method for str and unicode; a
5812 __format__() method to object, str, unicode, int, long, float, and
5813 datetime; the class string.Formatter; and the C API
5814 PyObject_Format().
5815
Georg Brandl3ee81df2008-05-17 18:14:43 +00005816- Fixed several potential crashes, all caused by specially crafted
5817 __del__ methods exploiting objects in temporarily inconsistent
5818 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005819
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005820- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00005821 prevent a possible crash: an Abstract Base Class would try to access
5822 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00005823

Georg Brandl3ee81df2008-05-17 18:14:43 +00005827- Clear all free lists during a gc.collect() of the highest generation
5828 in order to allow pymalloc to free more arenas. Python may give back
5829 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005830
Georg Brandl3ee81df2008-05-17 18:14:43 +00005831- Issue #2045: Fix an infinite recursion triggered when printing a
5832 subclass of collections.defaultdict, if its default_factory is set
5833 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005834
Christian Heimesf75dbef2008-02-08 00:11:31 +00005835- Fixed a minor memory leak in dictobject.c. The content of the free
5836 list was not freed on interpreter shutdown.
5837
Georg Brandl21e99f42010-03-07 15:23:59 +00005838- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00005839 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00005840
Georg Brandl3ee81df2008-05-17 18:14:43 +00005841- Patch #1953: Added ``sys._compact_freelists()`` and the C API
5842 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005843 to compact the internal free lists of pre-allocted ints and floats.
5844
Georg Brandl3ee81df2008-05-17 18:14:43 +00005845- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5846 calls. Python expected the return type int but the fork familie
5847 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00005848
Georg Brandl3ee81df2008-05-17 18:14:43 +00005849- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00005861- Patch #1473257: generator objects gain a gi_code attribute. This is
5862 the same object as the func_code attribute of the function that
5863 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005864
Georg Brandl3ee81df2008-05-17 18:14:43 +00005865- Issue #1920: "while 0" statements were completely removed by the
5866 compiler, even in the presence of an "else" clause, which is
5867 supposed to be run when the condition is false. Now the compiler
5868 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005869
Guido van Rossumeead05f2008-01-24 18:21:02 +00005870- A few crashers fixed: weakref_in_del.py (issue #1377858);
5871 loosing_dict_ref.py (issue #1303614, test67.py);
5872 borrowed_ref_[34].py (not in tracker).
5873

5877
Georg Brandl3ee81df2008-05-17 18:14:43 +00005878- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005879 several extension methods and modules do not work without unicode
5880 support.
5881
Georg Brandl26543b12008-01-21 18:36:51 +00005882- Issue #1882: when compiling code from a string, encoding cookies in the

5884
Georg Brandl14404b62008-01-19 19:27:05 +00005885- Issue #1679: "0x" was taken as a valid integer literal.
5886
Georg Brandl6caad7d2008-01-26 14:19:22 +00005887- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005888 added.
5889
Christian Heimesc94e2b52008-01-14 04:13:37 +00005890- sys.float_info / PyFloat_GetInfo: The floating point information
5891 object was converted from a dict to a specialized structseq object.
5892
Georg Brandl3ee81df2008-05-17 18:14:43 +00005893- Patch #1816: Added sys.flags structseq. It exposes the status of
5894 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005895
Georg Brandl3ee81df2008-05-17 18:14:43 +00005896- Objects/structseq.c: Implemented new structseq representation. The

5907
Georg Brandl3ee81df2008-05-17 18:14:43 +00005908- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5909 envvar and sys.dont_write_bytecode attribute. All these can be set
5910 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005911
Georg Brandl3ee81df2008-05-17 18:14:43 +00005912- Improve some exception messages when Windows fails to load an
5913 extension module. Now we get for example '%1 is not a valid Win32
5914 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00005921- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005922 and INF. float("nan"), float("inf") and float("-inf") now work on
5923 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005925- Compiler now generates simpler and faster code for dictionary
5926 literals. The oparg for BUILD_MAP now indicates an estimated
5927 dictionary size. There is a new opcode, STORE_MAP, for adding
5928 entries to the dictionary.

5958 file can now be directly executed by passing their name to the
5959 interpreter. The directory/zipfile is automatically inserted as the
5960 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005962- Issue #1265: Fix a problem with sys.settrace, if the tracing
5963 function uses a generator expression when at the same time the
5964 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005965
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005966- sets and frozensets now have an isdisjoint() method.

5971
Georg Brandl21e99f42010-03-07 15:23:59 +00005972- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005973 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5974 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005975
Georg Brandl3ee81df2008-05-17 18:14:43 +00005976- Issue #1686386: Tuple's tp_repr did not take into account the
5977 possibility of having a self-referential tuple, which is possible
5978 from C code. Nor did object's tp_str consider that a type's tp_str
5979 could do something that could lead to an inifinite recursion.
5980 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5981 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005982
Georg Brandl3ee81df2008-05-17 18:14:43 +00005983- Issue #1164: It was possible to trigger deadlock when using the
5984 'print' statement to write to a file since the GIL was not released
5985 as needed. Now PyObject_Print() does the right thing along with
5986 various tp_print implementations of the built-in types and those in
5987 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005988
Georg Brandl3ee81df2008-05-17 18:14:43 +00005989- Issue #1147: Exceptions were directly allowing string exceptions in
5990 their throw() method even though string exceptions no longer
5991 allowed.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005993- Issue #1096: Prevent a segfault from getting the repr of a very
5994 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00005995
Brett Cannon1e534b52007-09-07 04:18:30 +00005996- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005997 PyObject_Call() never calling back out to Python code to trigger
5998 recursion depth updates/checks. Required the creation of a static
5999 RuntimeError instance in case normalizing an exception put the
6000 recursion check value past its limit. Fixes crashers
6001 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00006002
Georg Brandl3ee81df2008-05-17 18:14:43 +00006003- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00006016- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006017 __*__ attributes. (Some already existed, e.g., __doc__ and
6018 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006019
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00006020- Add -3 option to the interpreter to warn about features that are
6021 deprecated and will be changed/removed in Python 3.0.
6022
Georg Brandl2134e752007-05-21 20:34:16 +00006023- Patch #1686487: you can now pass any mapping after '**' in function
6024 calls.
6025
Collin Winter62903052007-05-18 23:11:24 +00006026- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006027 "except E as target:". This is to provide forwards compatibility
6028 with Python 3.0.

Brett Cannon229cee22007-05-05 01:34:02 +00006030- Deprecate BaseException.message as per PEP 352.
6031
Georg Brandl3ee81df2008-05-17 18:14:43 +00006032- Issue #1303614: don't expose object's __dict__ when the dict is

Vinay Sajip8549ce32007-05-06 17:53:37 +00006035- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006036 setting a plain string, ie don't expand to single letter identifiers.
6037
Raymond Hettinger13936692007-04-11 18:40:58 +00006038- Request #1191699: Slices can now be pickled.
6039
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006040- Request #1193128: str.translate() now allows a None argument for
6041 translations that only remove characters without re-mapping the
6042 remaining characters.
6043
Georg Brandl5cb76c12007-03-21 09:00:39 +00006044- Patch #1682205: a TypeError while unpacking an iterable is no longer

6048
Guido van Rossum143b5642007-03-23 04:58:42 +00006049- Bug #1683368: The object.__init__() and object.__new__() methods are
6050 now stricter in rejecting excess arguments. The only time when
6051 either allows excess arguments is when it is not overridden and the
6052 other one is. For backwards compatibility, when both are
6053 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006054 warning later). Also, type.__init__() insists on the same signature
6055 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00006056
Georg Brandl3ee81df2008-05-17 18:14:43 +00006057- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6058 object to complex using its __complex__() method before falling back
6059 to the __float__() method. Therefore, the functions in the cmath
6060 module now can operate on objects that define a __complex__()
6061 method.
Georg Brandl2b869942007-03-17 16:08:45 +00006062
Georg Brandl3ee81df2008-05-17 18:14:43 +00006063- Patch #1623563: allow __class__ assignment for classes with
6064 __slots__. The old and the new class are still required to have the
6065 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00006066

6071 ``object.__reduce_ex__()`` is called with an object that is faking
6072 its type.

6078
Georg Brandl7b9c5552007-03-12 14:30:05 +00006079- Bug #1678647: write a newline after printing an exception in any
6080 case, even when converting the value to a string failed.
6081
Georg Brandl871f1bc2007-03-12 13:17:36 +00006082- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006083 its argument, if it exists. If not, it will work like before. This
6084 allows customizing the output of dir() in the presence of a
6085 __getattr__().

Collin Winter276887b2007-03-12 16:11:39 +00006087- Patch #922167: Python no longer segfaults when faced with infinitely
6088 self-recursive reload() calls (as reported by bug #742342).
6089
Georg Brandl3ee81df2008-05-17 18:14:43 +00006090- Patch #1675981: remove unreachable code from ``type.__new__()``

6094 parthensized forms. This means complex(repr(x)) now works instead of
6095 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006096
Georg Brandlaa2321b2007-03-07 00:40:28 +00006097- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006098 makes the filenames the warning module prints much more sensible
6099 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00006100

Georg Brandl0fca97a2007-03-05 22:28:08 +00006112- Patch #1674228: when assigning a slice (old-style), check for the
6113 sq_ass_slice instead of the sq_slice slot.
6114
Georg Brandl3ee81df2008-05-17 18:14:43 +00006115- When printing an unraisable error, don't print exceptions. before
6116 the name. This duplicates the behavior whening normally printing
6117 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006650 AttributeError instead of an IOError when the server's response
6651 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00006652

Georg Brandl3ee81df2008-05-17 18:14:43 +00006668- Patch #1530482: add pydoc.render_doc() which returns the

6683
Georg Brandl92a6bae2007-03-13 17:43:32 +00006684- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00006685 are set for invalid interpolation sequences that would lead to
6686 errors on reading back those values.

6740
Georg Brandl3ee81df2008-05-17 18:14:43 +00006741- unittest now verifies more of its assumptions. In particular,
6742 TestCase and TestSuite subclasses (not instances) are no longer
6743 accepted in TestSuite.addTest(). This should cause no
6744 incompatibility since it never made sense with ordinary subclasses
6745 -- the failure just occurred later, with a more cumbersome
6746 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007135 time so that opening a database previously created with the DB_DUP
7136 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7137 opens. Specifically: dictionary assignment to a DB object will
7138 replace all values for a given key when the database allows
7139 duplicate values. DB users should use DB.put(k, v) when they want
7140 to store duplicates; not DB[k] = v.

7149 behavior of quoting dots if they are the second character of any
7150 line.

7496 of w# format code incorrectly truncated the length to an int, even
7497 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
7498 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007528- Added case insensitive comparison methods ``PyOS_stricmp(char*,
7529 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
