Mark Dickinsondbbed042011-09-19 16:38:08 +010041- Issue #12973: Fix overflow checks that invoked undefined behaviour in

43 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +010044 compiler optimizing the check away. Also fix similar overflow checks
45 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These

72
Łukasz Langa7a153902011-10-18 17:16:00 +020073- Issue #10860: httplib now correctly handles an empty port after port

88 raised when the wrapped raw file is non-blocking and the write would block.
89 Previous code assumed that the raw write() would raise BlockingIOError, but
90 RawIOBase.write() is defined to returned None when the call would block.
91 Patch by sbt.
92

278
Ned Deily87e82bb2011-06-28 19:52:59 -0700279- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
280 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
281 interpreter process. This could cause failures in non-Distutils subprocesses
282 and was unreliable since tests or user programs could modify the interpreter
283 environment after Distutils set it. Instead, have Distutils set the the
284 deployment target only in the environment of each build subprocess. It is
285 still possible to globally override the default by setting
286 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
287 greater or equal to the default value, the value with which the interpreter
288 was built.

1194 received. Now sendall() properly calls signal handlers if necessary,
1195 and retries sending if these returned successfully, including on sockets
1196 with a timeout.

1213 by Andrew Bennetts.

1222
Raymond Hettinger20397532010-09-12 02:11:45 +00001223- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
1224 This prevents user-created self-referencing ordered dictionaries from
1225 becoming permanently uncollectable GC garbage. The downside is that
1226 removing __del__ means that the internal doubly-linked list has to wait for
1227 GC collection rather than freeing memory immediately when the refcnt drops
1228 to zero.
1229

1237 original error is re-raised.

1257 falling into recursion.
1258
R. David Murray7c4bf552010-08-25 01:45:57 +00001259- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
1260 character years even if the message contains RFC822 two character years.
1261
Daniel Stutzbach91287322010-08-24 21:09:30 +00001262- Issue #8750: Fixed MutableSet's methods to correctly handle

1275
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00001276- Issue #9617: Signals received during a low-level write operation aren't
1277 ignored by the buffered IO layer anymore.
1278
Benjamin Peterson52c36052010-08-21 03:03:22 +00001279- Issue #2521: Use weakrefs on for caching in the abc module, so that classes

1281
Raymond Hettingera54b2da2010-08-17 19:03:06 +00001282- Issue #9626: the view methods for collections.OrderedDict() were returning

Antoine Pitroue1436d12010-08-12 15:25:51 +00001290- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
1291 and a BadZipfile error is raised if it doesn't match (as used to be the
1292 case in Python 2.5 and earlier).
1293
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00001294- Issue #9550: a BufferedReader could issue an additional read when the
1295 original read request had been satisfied, which could block indefinitely
1296 when the underlying raw IO channel was e.g. a socket. Report and original
1297 patch by Jason V. Miller.
1298
Fred Drake0a1fa0e2010-08-10 13:09:54 +00001299- Issue #9551: Don't raise TypeError when setting the value to None for

1690 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00002048 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
2049 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's

2071-----------------
2072
Philip Jenveyaebbaeb2010-04-06 23:24:45 +00002073- Issue #7301: Add environment variable $PYTHONWARNINGS.
2074
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00002075- Issue #8329: Don't return the same lists from select.select when no fds are
2076 changed.
2077
Georg Brandlfee0f442010-05-22 21:26:21 +00002078- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00002079 on 64-bit machines. The shift count for either left or right shift is
2080 permitted to be up to sys.maxsize.
2081
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00002082- Ensure that tokenization of identifiers is not affected by locale.
2083
Georg Brandlfee0f442010-05-22 21:26:21 +00002084- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
Tarek Ziadé00002952010-04-03 08:37:59 +00002085
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +00002086- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
2087
Georg Brandlfee0f442010-05-22 21:26:21 +00002088- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2089 with a non-empty format string. This is an effort to future-proof user
2090 code. If a derived class does not currently implement __format__ but later
2091 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002092 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002093 Python 3.3 and it will be an error in Python 3.4.
Eric Smithd44b2fc2010-04-02 12:30:56 +00002094
Antoine Pitroua57df2c2010-03-31 21:32:15 +00002095- Issue #8268: Old-style classes (not just instances) now support weak

Victor Stinner66644262010-03-10 22:30:19 +00002108- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
Georg Brandlba83f822010-03-14 09:50:54 +00002109 (SIGINT). If an error occurs while importing the site module, the error is

2125
Georg Brandlfee0f442010-05-22 21:26:21 +00002126- Issue #8257: The Decimal construct now accepts a float instance directly,
2127 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00002128
2129 >>> Decimal(1.1)
2130 Decimal('1.100000000000000088817841970012523233890533447265625')
2131
Raymond Hettinger34c35b22010-04-03 10:22:00 +00002132- collections.Counter() now supports a subtract() method.
2133
Georg Brandlfee0f442010-05-22 21:26:21 +00002134- The functools module now has a total_ordering() class decorator to simplify
2135 the specification of rich comparisons.

Georg Brandlfee0f442010-05-22 21:26:21 +00002137- The functools module also adds cmp_to_key() as a tool to transition old-style
2138 comparison functions to new-style key-functions.
Raymond Hettingera551f312010-04-04 18:34:45 +00002139
Georg Brandlfee0f442010-05-22 21:26:21 +00002140- Issue #8294: The Fraction constructor now accepts Decimal and float instances
2141 directly.
Mark Dickinson7c63eee2010-04-02 22:27:36 +00002142
Georg Brandlfee0f442010-05-22 21:26:21 +00002143- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
2144 InvalidOperation instead of returning False. (Comparisons involving a quiet
2145 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2146 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00002147
Georg Brandlfee0f442010-05-22 21:26:21 +00002148- Issue #2531: Comparison operations between floats and Decimal instances now
2149 return a result based on the numeric values of the operands; previously they
2150 returned an arbitrary result based on the relative ordering of id(float) and
2151 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00002152
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002153- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00002154 argument `-` which tells it to read files to compile from stdin. Each line is
2155 read on demand and the named file is compiled immediately. (Original patch by
2156 Piotr Ożarowski).

Florent Xicluna58b65662010-03-30 16:29:03 +00002161- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
2162 form feed (0x0C) are now considered linebreaks, as specified in Unicode
Georg Brandlfee0f442010-05-22 21:26:21 +00002163 Standard Annex #14. See issue #7643. http://www.unicode.org/reports/tr14/
Florent Xicluna22b24382010-03-30 08:24:06 +00002164
Georg Brandlfee0f442010-05-22 21:26:21 +00002165- Comparisons using one of <, <=, >, >= between a complex instance and a
2166 Fractions instance now raise TypeError instead of returning True/False. This
2167 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2168 <=> complex, and complex <=> complex comparisons.

2268 integer format code, struct.pack first attempts to convert the non-integer

2273 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
2274 argument's __int__ method to convert to an integer before packing. It also
Georg Brandlfee0f442010-05-22 21:26:21 +00002275 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
2276 inconsistent: __int__ was used for some integer codes but not for others, and
2277 the set of integer codes for which it was used differed between native packing
2278 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00002530- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
2531 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
2532 returning NULL. The macro now returns a statically allocated empty string
2533 instead.

2543 strings,
2544 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long

Georg Brandlba83f822010-03-14 09:50:54 +00002579 specified, rather than fall through to AF_PACKET (in the ``socket`` module).

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002585- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00002586 file position when calling `truncate()`. It would previously change the file
2587 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002588 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
2589
Georg Brandlba83f822010-03-14 09:50:54 +00002590- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
2591 class used to represent files stored inside an archive. The new
2592 implementation is significantly faster and can be wrapped in a
2593 ``io.BufferedReader`` object for more speedups. It also solves an issue
2594 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
2595 Patch by Nir Aides.

Benjamin Petersona43f34c2010-01-25 03:31:13 +00002604
Georg Brandlba83f822010-03-14 09:50:54 +00002605- Issue #7748: Since unicode values are supported for some metadata options in
2606 Distutils, the DistributionMetadata get_* methods will now return an utf-8
2607 encoded string for them. This ensures that the upload and register commands
2608 send the correct values to PyPI without any error.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +00002878
Georg Brandlba83f822010-03-14 09:50:54 +00002879- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2880 decimal string that's guaranteed to round back to x under correct rounding
2881 (with round-half-to-even rounding mode). Previously it gave a string based on
2882 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2883 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2884 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002885
Georg Brandlba83f822010-03-14 09:50:54 +00002886- Issue #7117: On almost all platforms: float-to-string and string-to-float
2887 conversions within Python are now correctly rounded. Places these conversions
2888 occur include: str for floats and complex numbers; the float and complex
2889 constructors; old-style and new-style numeric formatting; serialization and
2890 deserialization of floats and complex numbers using marshal, pickle and json;
2891 parsing of float and imaginary literals in Python code; Decimal-to-float
2892 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002893
Georg Brandlba83f822010-03-14 09:50:54 +00002894 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2895 providing correctly-rounded strtod and dtoa C functions. This code is
2896 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2897 the C compiler. There may be a small number of platforms on which correct
2898 operation of this code cannot be guaranteed, so the code is not used: notably,
2899 this applies to platforms where the C double format is not IEEE 754 binary64,
2900 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2901 and Python's configure script is unable to determine how to change the FPU
2902 precision. On these platforms conversions use the platform strtod and dtoa,
2903 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002904
Georg Brandlba83f822010-03-14 09:50:54 +00002905- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2906 uses the correctly-rounded string <-> float conversions described above (when
2907 available), and so produces correctly rounded results that will display nicely
2908 under the float repr. There are two related small changes: (1) round now
2909 accepts any class with an ``__index__()`` method for its second argument (but
2910 no longer accepts floats for the second argument), and (2) an excessively
2911 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2912 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00003059- Issue #5920: For ``float.__format__()``, change the behavior with the empty
3060 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
3061 but with at least one decimal point and with a default precision
3062 of 12. Previously, the behavior the same but with a default precision of 6.
3063 This more closely matches ``str()``, and reduces surprises when adding
3064 alignment flags to the empty presentation type. This also affects the new
3065 complex.__format__ in the same way.
3066
3067- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

Georg Brandlba83f822010-03-14 09:50:54 +00003205- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
3206 existing .py counterpart, override the co_filename attributes of all code
3207 objects if the original filename is obsolete (which can happen if the file has

3262
Georg Brandlba83f822010-03-14 09:50:54 +00003263- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
3264 file objects with closefd=False. The file descriptor is still kept open but
3265 the file object behaves like a closed file. The ``FileIO`` object also got a
3266 new readonly attribute ``closefd``.

Benjamin Peterson399b1fe2008-10-25 02:53:28 +00003286- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning

Georg Brandlba83f822010-03-14 09:50:54 +00003289- On windows, ``os.chdir()`` given unicode was not working if
3290 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
3291 this code path is really executed because I cannot move to such directory on
3292 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00003294- Issue #4069: When ``set.remove(element)`` is used with a set element, the
3295 element is temporarily replaced with an equivalent frozenset. But the
3296 eventual KeyError would always report the empty ``frozenset()`` as the missing
3297 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00003317- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
3318 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
3319 step. This avoids problems with counting UTF-8 bytes that ignores the effect
3320 of using the replace error handler in PyUnicode_DecodeUTF8().
3321
Walter Dörwald726ba8e2009-05-06 14:32:35 +00003322- Issue #3739: The unicode-internal encoder now reports the number of characters

3324
Georg Brandlba83f822010-03-14 09:50:54 +00003325- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
3326 allocator will be automatically disabled when running under Valgrind. This
3327 gives improved memory leak detection when running under Valgrind, while taking
3328 advantage of pymalloc at other times.

Georg Brandlba83f822010-03-14 09:50:54 +00004551 leak-chasing test runs give sensible results. The previous method of reaping
4552 threads could return successfully while some Thread objects were still
4553 referenced. This also introduces a new private function: ``thread._count()``.

Guilherme Polo7f146ab2009-06-21 17:22:50 +00004570- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
4571 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00004572 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
4573 the tests if DISPLAY is defined but can't be used.

4579 import both normal and optimised versions of modules. test_heapq and
4580 test_warnings have been adjusted to use it, tests for other modules with both
4581 C and Python implementations in the stdlib can be adjusted to use it over
4582 time.

Georg Brandlba83f822010-03-14 09:50:54 +00004590- regrtest no longer treats ImportError as equivalent to SkipTest. Imports that
4591 should cause a test to be skipped are now done using import_module from test
4592 support, which does the conversion.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004695- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4696 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4697 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4698 ``printf`` function, whereas PyString_FromFormat has an independent
4699 implementation and uses "%zd" on all platforms for size_t values.
4700 This makes a difference on win64, where ``printf`` needs "%Id" to display
4701 64bit values.

4707 object; previously an int would be returned for small values. the __long__
4708 method is allowed to return either an int or a long, but the behaviour of

Antoine Pitrou0668c622008-08-26 22:42:08 +00004721 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4722 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4723 when given a tuple of classes as second argument, were looking up
4724 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4725 type object.

Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00004823- Issue #2975: When compiling several extension modules with Visual Studio 2008
4824 from the same python interpreter, some environment variables would grow
4825 without limit.
4826
Benjamin Peterson37346b22008-08-23 20:27:43 +00004827- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

4843 wrapper for warnings.catch_warnings() that makes it easier to check
4844 that expected warning messages are being reported.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004864What's New in Python 2.6 beta 3?
4865================================
4866
Barry Warsaw07a4a382008-08-21 01:15:08 +00004867*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004868
4869Core and Builtins
4870-----------------
4871
Guido van Rossumf8402962008-08-20 15:01:50 +00004872- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4873 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4874 extensions do not automatically benefit from the class attribute
4875 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4876 to their tp_flags field if they care. This is a backwards
4877 compatibility feature; in 3.0, all types will use the cache by
4878 default.
4879
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004880- Keyword arguments can now follow starred arguments. (``f(a, *args,
4881 keyword=23)`` is now valid syntax.)
4882
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004883- ctypes function pointers that are COM methods have a boolean True
4884 value again.
4885
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004886- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4887 by denying s# to parse objects that have a releasebuffer procedure,
4888 and introducing s*.
4889
Georg Brandl1e13ea92008-08-11 09:07:59 +00004890- Issue #3537: Fix an assertion failure when an empty but presized dict
4891 object was stored in the freelist.
4892
Mark Dickinsonb6467572008-08-04 21:30:09 +00004893- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4894 ValueError consistently across platforms.
4895
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004896- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4897 (64bit Unix, for example), unichr() would truncate its argument and return
4898 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4899
Neal Norwitze7d8be82008-07-31 17:17:14 +00004900- Apply security patches from Apple.
4901
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004902- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4903 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4904
Antoine Pitrou92f82162008-07-25 22:22:08 +00004905- Issue #1819: function calls with several named parameters are now on
4906 average 35% faster (as measured by pybench).
4907
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004908- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4909 the python debugger steps into a class statement: the free variables (local
4910 variables defined in an outer scope) would be deleted from the outer scope.
4911
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004912- Issue #2620: Overflow checking when allocating or reallocating memory
4913 was not always being done properly in some python types and extension
4914 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4915 all been updated to perform better checks and places in the code that
4916 would previously leak memory on the error path when such an allocation
4917 failed have been fixed.
4918
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004919Library
4920-------
4921
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00004922- Issue #3612: Added some missing basic types in ctypes.wintypes.
4923
Benjamin Petersone977ad42008-08-20 01:42:01 +00004924- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4925 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4926
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004927- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4928 version reported by these tools does not necessarily follow the python
4929 version numbering scheme, so the module is less strict when parsing it.
4930
Nick Coghlanf70385a2008-08-18 12:42:46 +00004931- Issue #2235: Added Py3k warnings for types which will become unhashable
4932 under the stricter __hash__ inheritance rules in 3.0. Several types
4933 which did not meet the rules for hash invariants and were already
4934 unhashable in 3.0 have now been explicitly flagged as unhashable in
4935 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4936 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4937
Brett Cannon88f801d2008-08-18 00:46:22 +00004938- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4939 imported into the module but exposed as part of the module's API.
4940
Brett Cannon7b96f072008-08-18 00:41:11 +00004941- Remove an unneeded import of abc.ABCMeta from 'inspect'.
4942
Brett Cannon46225e72008-08-18 00:36:52 +00004943- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
4944
Brett Cannon25c9d6a2008-08-17 22:10:11 +00004945- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
4946
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004947- Issue #3575: Incremental decoder's decode function now takes bytearray
4948 by using 's*' instead of 't#'.
4949
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004950- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004951 fails unicode conversion on 2nd parameter. (windows only)
4952
Georg Brandl222e2082010-08-01 22:27:39 +00004953- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004954 in a redirect.
4955
Brett Cannonabe423e2008-08-16 21:47:07 +00004956- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00004957 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004958
Facundo Batistaeb90b782008-08-16 14:44:07 +00004959- Issue #2776: fixed small issue when handling an URL with double slash
4960 after a 302 response in the case of not going through a proxy.
4961
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004962- Issue #2676: in the email package, content-type parsing was hanging on
4963 pathological input because of quadratic or exponential behaviour of a
4964 regular expression.
4965
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004966- Issue #3476: binary buffered reading through the new "io" library is now
4967 thread-safe.
4968
Brett Cannonbf3157b2008-08-14 05:00:03 +00004969- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4970 since mimetools itself is deprecated. Because modules are cached, all
4971 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4972
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004973- Issue #3134: shutil referenced undefined WindowsError symbol.
4974
Robert Schuppenies14646332008-08-10 11:01:53 +00004975- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4976 menu entries were not deleted.
4977
Brett Cannon83e81842008-08-09 23:30:55 +00004978- Copied the implementation of reduce() to _functools.reduce() to have a
4979 version that did not raise a DeprecationWarning under -3.
4980
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004981- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4982 a MemoryError rather than silently stop the iteration.
4983
Guido van Rossum59ce9012008-08-09 14:55:34 +00004984- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4985 to _sre.compile() will now be rejected. This should not affect anybody
4986 since the re.compile() function never generates invalid re-bytecode.
4987
Skip Montanaroa032bf42008-08-08 22:52:51 +00004988- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4989 upon first access it can be automatically initialized from the csv file if
4990 it wasn't initialized during instantiation.
4991
Brett Cannon3aa2a492008-08-06 22:28:09 +00004992- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4993 the reload() built-in has been removed.
4994
Brett Cannon7e30b672008-08-04 21:52:25 +00004995- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00004996 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Brett Cannon7e30b672008-08-04 21:52:25 +00005002
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00005003- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
5004 raised an AttributeError.
5005
Benjamin Peterson01a24322008-07-28 23:35:27 +00005006- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00005007 asking for a specific length. This problem only affected files opened
5008 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00005009
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00005010- Issue #3449: Update decimal module to use most recent specification
5011 (v. 1.68) and tests (v. 2.58) from IBM.
5012
Georg Brandl222e2082010-08-01 22:27:39 +00005013- Issue #3437: Bug fix in robotparser parsing of Allow: lines.

5017
Georg Brandlf9efabb2008-07-23 15:16:45 +00005018- Deprecate the "ast" parser function aliases.
5019
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005020- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
5021
5022- Issue #3303: Fix a crash in locale.strcoll() when calling it with
5023 invalid arguments.
5024
5025- Issue #3302: Fix several crashes when calling locale's gettext functions
5026 with None arguments.
5027
5028- Issue #3389: Allow resolving dotted names for handlers in logging
5029 configuration files.
5030

5032
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00005033- Issue #3394: zipfile.writestr sets external attributes when passed a
5034 file name rather than a ZipInfo instance, so files are extracted with
5035 mode 0600 rather than 000 under Unix.
5036
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00005037- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
5038 argument in python 2.5, this broke code that subclassed Popen to include its
5039 own poll method. Fixed my moving _deadstate to an _internal_poll method.

5047-------------
5048
Nick Coghlan6e8fef02008-08-18 13:14:22 +00005049- Issue #2235: the C API function PyObject_HashNotImplemented and its
5050 interaction with the tp_hash slot (added in 2.6b2) are now documented
5051
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00005052- Issue #643841: The language reference now provides more detailed
5053 coverage of the lookup process for special methods. The disclaimers
5054 regarding lack of coverage of new-style classes have also been
5055 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00005058What's New in Python 2.6 beta 2?
5059================================
5060
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005061*Release date: 17-Jul-2008*
5062
Raymond Hettingere3ae6552008-06-20 04:18:15 +00005063Core and Builtins
5064-----------------
5065
Georg Brandl3e483f62008-07-16 22:57:41 +00005066- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5067 its methods now allow for items objects that can be converted to
5068 an integer using operator.index().
5069
Mark Dickinson64b7e502008-07-16 09:40:03 +00005070- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5071 produced a ValueError instead of giving the correct float.
5072
Eric Smitha5fa5a22008-07-16 00:11:49 +00005073- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5074 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5075
Mark Dickinson7103aa42008-07-15 19:08:33 +00005076- Issue #3008: the float type has a new instance method 'float.hex'
5077 and a new class method 'float.fromhex' to convert floating-point
5078 numbers to and from hexadecimal strings, respectively.
5079
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005080- Issue #2235: __hash__ is once again inherited by default. To allow
5081 collections.Hashable to remain meaningful in the presence of the
5082 default hash implementation (object.__hash__), it is now possible
5083 to explicit block inheritance of hash by setting __hash__=None at
5084 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5085 level.
5086
Nick Coghlanb028f502008-07-13 14:52:36 +00005087- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5088 the parent module cannot be found while performing an absolute import.
5089 This means that an incorrectly defined __package__ attribute will
5090 now only prevent relative imports in that module rather than causing
5091 all imports from that module to fail.
5092
Nick Coghlan14ff9942008-07-08 14:21:42 +00005093- Issue #2517: Allow unicode messages in Exceptions again by correctly
5094 bypassing the instance dictionary when looking up __unicode__ on
5095 new-style classes.
5096
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00005097- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
5098 set to a custom object whose write() method happens to install
5099 another file in sys.stdout.
5100
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00005101- Issue #3088: Corrected a race condition in classes derived from
5102 threading.local: the first member set by a thread could be saved in
5103 another thread's dictionary.
5104
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005105- Issue #3004: Minor change to slice.indices(): the start and stop
5106 arguments are now treated identically, making the behaviour easier
5107 to describe and understand. For example, slice(None, -10,
5108 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5109 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5110 10, -1).
5111
Georg Brandl278fc502008-07-19 12:46:12 +00005112- Issue #3219: Calling a function with repeated keyword arguments,
5113 f(a=2, a=23), would not cause a syntax error. This was a regression

Georg Brandl5cc774e2008-06-11 20:28:06 +00005564 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00005565
5566 This is controlled by the configure argument ``--with-universal-archs``:
5567

5569
5570 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
5571
5572 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
5573

Georg Brandl3ee81df2008-05-17 18:14:43 +00005626- Issue #1631171: Re-implement the 'warnings' module in C (the
5627 original Python code has been kept as backup). This will allow for
5628 using the 'warning's machinery in such places as the parser where
5629 use of pure Python code is not possible. Both the ``showarning()``
5630 and ``formatwarning()`` gain an optional 'line' argument which is
5631 not called by default for backwards-compatibility reasons. Setting
5632 ``warnings.showwarning()`` to an implementation that lacks support
5633 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005696- Issue #2550: The approach used by client/server code for obtaining
5697 ports to listen on in network-oriented tests has been refined in an
5698 effort to facilitate running multiple instances of the entire
5699 regression test suite in parallel without issue.
5700 test_support.bind_port() has been fixed such that it will always
5701 return a unique port -- which wasn't always the case with the
5702 previous implementation, especially if socket options had been set
5703 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5704 new implementation of bind_port() will actually raise an exception
5705 if it is passed an AF_INET/SOCK_STREAM socket with either the
5706 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5707 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5708 the socket it's been passed. This currently only applies to
5709 Windows. This option prevents any other sockets from binding to the
5710 host/port we've bound to, thus removing the possibility of the
5711 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5712 when a second SOCK_STREAM socket binds and accepts to a host/port
5713 that's already been bound by another socket. The optional preferred
5714 port parameter to bind_port() has been removed. Under no
5715 circumstances should tests be hard coding ports!
5716
5717 test_support.find_unused_port() has also been introduced, which will
5718 pass a temporary socket object to bind_port() in order to obtain an
5719 unused port. The temporary socket object is then closed and
5720 deleted, and the port is returned. This method should only be used
5721 for obtaining an unused port in order to pass to an external program
5722 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5723 a parameter to a server-oriented class that doesn't give you direct
5724 access to the underlying socket used.
5725
5726 Finally, test_support.HOST has been introduced, which should be used
5727 for the host argument of any relevant socket calls (i.e. bind and
5728 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005729
5730 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005731 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005732 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5733 test_asynchat and test_socket_ssl.
5734
Georg Brandl3ee81df2008-05-17 18:14:43 +00005735 It is now possible for multiple instances of the regression test
5736 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00006015- Added the future_builtins module, which contains hex() and oct().
6016 These are the PEP 3127 version of these functions, designed to be
6017 compatible with the hex() and oct() builtins from Python 3.0. They
6018 differ slightly in their output formats from the existing, unchanged
6019 Python 2.6 builtins. The expected usage of the future_builtins
6020 module is:
6021 from future_builtins import hex, oct
6022
Eric Smith7ef40bf2008-02-20 23:34:22 +00006023- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6024 exponents for exponents with absolute value < 100. Follows C99
6025 standard. This is a change on Windows, which would use 3 digits.
6026 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6027 so that any alterations it does to the resulting string will be
6028 available in stringlib/formatter.h (for float.__format__).
6029
Eric Smith5a3c1352008-02-19 13:21:56 +00006030- Implemented PEP 3101, Advanced String Formatting. This adds a new
6031 builtin format(); a format() method for str and unicode; a
6032 __format__() method to object, str, unicode, int, long, float, and
6033 datetime; the class string.Formatter; and the C API
6034 PyObject_Format().
6035
Georg Brandl3ee81df2008-05-17 18:14:43 +00006036- Fixed several potential crashes, all caused by specially crafted
6037 __del__ methods exploiting objects in temporarily inconsistent
6038 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006039
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006040- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006041 prevent a possible crash: an Abstract Base Class would try to access
6042 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00006043

Georg Brandl3ee81df2008-05-17 18:14:43 +00006047- Clear all free lists during a gc.collect() of the highest generation
6048 in order to allow pymalloc to free more arenas. Python may give back
6049 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006050
Georg Brandl3ee81df2008-05-17 18:14:43 +00006051- Issue #2045: Fix an infinite recursion triggered when printing a
6052 subclass of collections.defaultdict, if its default_factory is set
6053 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006054
Christian Heimesf75dbef2008-02-08 00:11:31 +00006055- Fixed a minor memory leak in dictobject.c. The content of the free
6056 list was not freed on interpreter shutdown.
6057
Georg Brandl21e99f42010-03-07 15:23:59 +00006058- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00006059 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00006060
Georg Brandl3ee81df2008-05-17 18:14:43 +00006061- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6062 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006063 to compact the internal free lists of pre-allocted ints and floats.
6064
Georg Brandl3ee81df2008-05-17 18:14:43 +00006065- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6066 calls. Python expected the return type int but the fork familie
6067 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006068
Georg Brandl3ee81df2008-05-17 18:14:43 +00006069- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00006081- Patch #1473257: generator objects gain a gi_code attribute. This is
6082 the same object as the func_code attribute of the function that
6083 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006084
Georg Brandl3ee81df2008-05-17 18:14:43 +00006085- Issue #1920: "while 0" statements were completely removed by the
6086 compiler, even in the presence of an "else" clause, which is
6087 supposed to be run when the condition is false. Now the compiler
6088 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006089
Guido van Rossumeead05f2008-01-24 18:21:02 +00006090- A few crashers fixed: weakref_in_del.py (issue #1377858);
6091 loosing_dict_ref.py (issue #1303614, test67.py);
6092 borrowed_ref_[34].py (not in tracker).
6093
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006094- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006095 suppressed while an extension is loaded by calling SetErrorMode in
6096 dynload_win.c. The error is still reported properly.
6097
Georg Brandl3ee81df2008-05-17 18:14:43 +00006098- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006099 several extension methods and modules do not work without unicode
6100 support.
6101
Georg Brandl26543b12008-01-21 18:36:51 +00006102- Issue #1882: when compiling code from a string, encoding cookies in the
6103 second line of code were not always recognized correctly.
6104
Georg Brandl14404b62008-01-19 19:27:05 +00006105- Issue #1679: "0x" was taken as a valid integer literal.
6106
Georg Brandl6caad7d2008-01-26 14:19:22 +00006107- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006108 added.
6109
Christian Heimesc94e2b52008-01-14 04:13:37 +00006110- sys.float_info / PyFloat_GetInfo: The floating point information
6111 object was converted from a dict to a specialized structseq object.
6112
Georg Brandl3ee81df2008-05-17 18:14:43 +00006113- Patch #1816: Added sys.flags structseq. It exposes the status of
6114 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006115
Georg Brandl3ee81df2008-05-17 18:14:43 +00006116- Objects/structseq.c: Implemented new structseq representation. The

Georg Brandl3ee81df2008-05-17 18:14:43 +00006142 and INF. float("nan"), float("inf") and float("-inf") now work on
6143 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006144
Georg Brandl3ee81df2008-05-17 18:14:43 +00006145- Compiler now generates simpler and faster code for dictionary
6146 literals. The oparg for BUILD_MAP now indicates an estimated
6147 dictionary size. There is a new opcode, STORE_MAP, for adding
6148 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006177- Patch #1739468: Directories and zipfiles containing a __main__.py
6178 file can now be directly executed by passing their name to the
6179 interpreter. The directory/zipfile is automatically inserted as the
6180 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006182- Issue #1265: Fix a problem with sys.settrace, if the tracing
6183 function uses a generator expression when at the same time the
6184 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006185
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006186- sets and frozensets now have an isdisjoint() method.
6187

6189
Neal Norwitz44f326e2007-10-05 05:29:17 +00006190- Fix warnings found by the new version of the Coverity checker.
6191
Georg Brandl21e99f42010-03-07 15:23:59 +00006192- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006193 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6194 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006195
Georg Brandl3ee81df2008-05-17 18:14:43 +00006196- Issue #1686386: Tuple's tp_repr did not take into account the
6197 possibility of having a self-referential tuple, which is possible
6198 from C code. Nor did object's tp_str consider that a type's tp_str
6199 could do something that could lead to an inifinite recursion.
6200 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6201 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006202
Georg Brandl3ee81df2008-05-17 18:14:43 +00006203- Issue #1164: It was possible to trigger deadlock when using the
6204 'print' statement to write to a file since the GIL was not released
6205 as needed. Now PyObject_Print() does the right thing along with
6206 various tp_print implementations of the built-in types and those in
6207 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006208
Georg Brandl3ee81df2008-05-17 18:14:43 +00006209- Issue #1147: Exceptions were directly allowing string exceptions in
6210 their throw() method even though string exceptions no longer
6211 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00006212
Georg Brandl3ee81df2008-05-17 18:14:43 +00006213- Issue #1096: Prevent a segfault from getting the repr of a very
6214 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00006215
Brett Cannon1e534b52007-09-07 04:18:30 +00006216- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006217 PyObject_Call() never calling back out to Python code to trigger
6218 recursion depth updates/checks. Required the creation of a static
6219 RuntimeError instance in case normalizing an exception put the
6220 recursion check value past its limit. Fixes crashers
6221 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00006222
Georg Brandl3ee81df2008-05-17 18:14:43 +00006223- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00006236- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006237 __*__ attributes. (Some already existed, e.g., __doc__ and
6238 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006239
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00006240- Add -3 option to the interpreter to warn about features that are
6241 deprecated and will be changed/removed in Python 3.0.
6242
Georg Brandl2134e752007-05-21 20:34:16 +00006243- Patch #1686487: you can now pass any mapping after '**' in function
6244 calls.
6245
Collin Winter62903052007-05-18 23:11:24 +00006246- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006247 "except E as target:". This is to provide forwards compatibility
6248 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00006249
Brett Cannon229cee22007-05-05 01:34:02 +00006250- Deprecate BaseException.message as per PEP 352.
6251
Georg Brandl3ee81df2008-05-17 18:14:43 +00006252- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00006253 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00006254
Vinay Sajip8549ce32007-05-06 17:53:37 +00006255- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006256 setting a plain string, ie don't expand to single letter identifiers.
6257
Raymond Hettinger13936692007-04-11 18:40:58 +00006258- Request #1191699: Slices can now be pickled.
6259
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006260- Request #1193128: str.translate() now allows a None argument for
6261 translations that only remove characters without re-mapping the
6262 remaining characters.
6263
Georg Brandl5cb76c12007-03-21 09:00:39 +00006264- Patch #1682205: a TypeError while unpacking an iterable is no longer
6265 masked by a generic one with the message "unpack non-sequence".
6266
Neal Norwitzaa754b72007-03-21 06:39:48 +00006267- Remove unused file Python/fmod.c.
6268
Guido van Rossum143b5642007-03-23 04:58:42 +00006269- Bug #1683368: The object.__init__() and object.__new__() methods are
6270 now stricter in rejecting excess arguments. The only time when
6271 either allows excess arguments is when it is not overridden and the
6272 other one is. For backwards compatibility, when both are
6273 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006274 warning later). Also, type.__init__() insists on the same signature
6275 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00006276
Georg Brandl3ee81df2008-05-17 18:14:43 +00006277- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6278 object to complex using its __complex__() method before falling back
6279 to the __float__() method. Therefore, the functions in the cmath
6280 module now can operate on objects that define a __complex__()
6281 method.
Georg Brandl2b869942007-03-17 16:08:45 +00006282
Georg Brandl3ee81df2008-05-17 18:14:43 +00006283- Patch #1623563: allow __class__ assignment for classes with
6284 __slots__. The old and the new class are still required to have the
6285 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00006286

6291 ``object.__reduce_ex__()`` is called with an object that is faking
6292 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00006293
Georg Brandl3ee81df2008-05-17 18:14:43 +00006294- Patch #1680015: Don't modify __slots__ tuple if it contains an

6298
Georg Brandl7b9c5552007-03-12 14:30:05 +00006299- Bug #1678647: write a newline after printing an exception in any
6300 case, even when converting the value to a string failed.
6301
Georg Brandl871f1bc2007-03-12 13:17:36 +00006302- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006303 its argument, if it exists. If not, it will work like before. This
6304 allows customizing the output of dir() in the presence of a
6305 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00006306
Collin Winter276887b2007-03-12 16:11:39 +00006307- Patch #922167: Python no longer segfaults when faced with infinitely
6308 self-recursive reload() calls (as reported by bug #742342).
6309
Georg Brandl3ee81df2008-05-17 18:14:43 +00006310- Patch #1675981: remove unreachable code from ``type.__new__()``
6311 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006313- Patch #1491866: change the complex() constructor to allow
6314 parthensized forms. This means complex(repr(x)) now works instead of
6315 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006316
Georg Brandlaa2321b2007-03-07 00:40:28 +00006317- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006318 makes the filenames the warning module prints much more sensible
6319 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00006320
Georg Brandl49aafc92007-03-07 00:34:46 +00006321- Variant of patch #697613: don't exit the interpreter on a SystemExit
6322 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00006323 variable is given, but break into the interactive interpreter just
6324 like on other exceptions or normal program exit.

6330 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00006331
Georg Brandl0fca97a2007-03-05 22:28:08 +00006332- Patch #1674228: when assigning a slice (old-style), check for the
6333 sq_ass_slice instead of the sq_slice slot.
6334
Georg Brandl3ee81df2008-05-17 18:14:43 +00006335- When printing an unraisable error, don't print exceptions. before
6336 the name. This duplicates the behavior whening normally printing
6337 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00006338
Georg Brandl3ee81df2008-05-17 18:14:43 +00006339- Bug #1653736: Properly discard third argument to

6346 created a weakref on itself during a __del__ call for new-style
6347 classes (classic classes still have the bug).

6962 TestCase and TestSuite subclasses (not instances) are no longer
6963 accepted in TestSuite.addTest(). This should cause no

6965 -- the failure just occurred later, with a more cumbersome
6966 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007247- Issue #829951: In the smtplib module, SMTP.starttls() now complies
7248 with RFC 3207 and forgets any knowledge obtained from the server not
7249 obtained from the TLS negotiation itself. Patch contributed by Bill
7250 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00007251
Georg Brandl3ee81df2008-05-17 18:14:43 +00007252- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00007253 that the SMTP.starttls() caller no longer needs to call ehlo()
7254 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00007255 does not claim to support starttls. Adds the
7256 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
7257 Fenner.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007311- itertools.chain() now has an alternate constructor,

7337 complex, tuple, list, dict, set, and frozenset. Formerly, it would
7338 silently miscode subclasses of those types. Now, it raises a
7339 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00007340

Georg Brandl3ee81df2008-05-17 18:14:43 +00007355 time so that opening a database previously created with the DB_DUP
7356 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7357 opens. Specifically: dictionary assignment to a DB object will
7358 replace all values for a given key when the database allows
7359 duplicate values. DB users should use DB.put(k, v) when they want
7360 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00007361

7367 characters with ASCII value less than 32. Also, it correctly quotes
7368 dots only if they occur on a single line, as opposed to the previous
7369 behavior of quoting dots if they are the second character of any
7370 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00007371

Georg Brandl3ee81df2008-05-17 18:14:43 +00007640 periodic threadstate and signal checking in tight loops. By
7641 default, this option is turned-off. It should only be enabled in
7642 debugged, performance critical applications.

Christian Heimes5b970ad2008-02-06 13:33:44 +00007699
Georg Brandl3ee81df2008-05-17 18:14:43 +00007700- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
7701 to ``PyTuple_SetItem``, it can be used to populate a brand new

7714
Georg Brandl3ee81df2008-05-17 18:14:43 +00007715- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
7716 of w# format code incorrectly truncated the length to an int, even
7717 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
7718 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00007719
Georg Brandl3ee81df2008-05-17 18:14:43 +00007720- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

7742 outside of pystate.c and should not be necessary.
7743
Georg Brandl3ee81df2008-05-17 18:14:43 +00007744- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do

Georg Brandl3ee81df2008-05-17 18:14:43 +00007748- Added case insensitive comparison methods ``PyOS_stricmp(char*,
7749 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00007750
Georg Brandl3ee81df2008-05-17 18:14:43 +00007751- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

7761 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00007762

Georg Brandl3ee81df2008-05-17 18:14:43 +00007776- Removed the macfs module. It had been deprecated since Python 2.5.
7777 This lead to the deprecation of macostools.touched() as it relied
7778 solely on macfs and was a no-op under OS X.
