212 int.__pow__. These overflow checks were causing int.__pow__ to produce

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

Ned Deilyc47a4592012-02-11 20:40:24 +0100285 has left two versions of customize_compiler, the original in
286 distutils.sysconfig and another copy in distutils.ccompiler, with some

290
Ned Deily0d0ea482012-02-10 12:59:06 +0100291- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
292 Distutils-based packages with C extension modules may fail because
293 Apple has removed gcc-4.2, the version used to build python.org
294 64-bit/32-bit Pythons. If the user does not explicitly override
295 the default C compiler by setting the CC environment variable,
296 Distutils will now attempt to compile extension modules with clang
297 if gcc-4.2 is required but not found. Also as a convenience, if
298 the user does explicitly set CC, substitute its value as the default
299 compiler in the Distutils LDSHARED configuration variable for OS X.
300 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
301 SDK, neither of which are available in Xcode 4. This change does not
302 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -0700575- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
576 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
577 interpreter process. This could cause failures in non-Distutils subprocesses
578 and was unreliable since tests or user programs could modify the interpreter
579 environment after Distutils set it. Instead, have Distutils set the the
580 deployment target only in the environment of each build subprocess. It is
581 still possible to globally override the default by setting
582 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
583 greater or equal to the default value, the value with which the interpreter
584 was built.

614 the ticker doesn't have to wind down to zero from the old starting point

616 interval, it makes sure the new limit takes effect right away rather have an
617 early task switch before recognizing the new interval.

1562 This prevents user-created self-referencing ordered dictionaries from
1563 becoming permanently uncollectable GC garbage. The downside is that
1564 removing __del__ means that the internal doubly-linked list has to wait for
1565 GC collection rather than freeing memory immediately when the refcnt drops
1566 to zero.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00002025- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
2026 start byte and the continuation byte(s) are now considered invalid, instead
2027 of the number of bytes specified by the start byte.
2028 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
2029 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte

2041 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Philip Jenveyaebbaeb2010-04-06 23:24:45 +00002411- Issue #7301: Add environment variable $PYTHONWARNINGS.
2412
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00002413- Issue #8329: Don't return the same lists from select.select when no fds are
2414 changed.
2415
Georg Brandlfee0f442010-05-22 21:26:21 +00002416- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00002417 on 64-bit machines. The shift count for either left or right shift is
2418 permitted to be up to sys.maxsize.

2425
Georg Brandlfee0f442010-05-22 21:26:21 +00002426- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2427 with a non-empty format string. This is an effort to future-proof user
2428 code. If a derived class does not currently implement __format__ but later
2429 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002430 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002431 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00002464- Issue #8257: The Decimal construct now accepts a float instance directly,
2465 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00002466

Georg Brandlfee0f442010-05-22 21:26:21 +00002481- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
2482 InvalidOperation instead of returning False. (Comparisons involving a quiet
2483 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
2484 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00002485
Georg Brandlfee0f442010-05-22 21:26:21 +00002486- Issue #2531: Comparison operations between floats and Decimal instances now
2487 return a result based on the numeric values of the operands; previously they
2488 returned an arbitrary result based on the relative ordering of id(float) and
2489 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +00002490
Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002491- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00002492 argument `-` which tells it to read files to compile from stdin. Each line is
2493 read on demand and the named file is compiled immediately. (Original patch by

Georg Brandlfee0f442010-05-22 21:26:21 +00002503- Comparisons using one of <, <=, >, >= between a complex instance and a
2504 Fractions instance now raise TypeError instead of returning True/False. This
2505 makes Fraction <=> complex comparisons consistent with int <=> complex, float
2506 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00002868- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
2869 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
2870 returning NULL. The macro now returns a statically allocated empty string
2871 instead.

Antoine Pitroud840e512010-02-04 20:20:18 +00002916- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00002917 specified, rather than fall through to AF_PACKET (in the ``socket`` module).

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002923- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00002924 file position when calling `truncate()`. It would previously change the file
2925 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002926 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
2927

2929 class used to represent files stored inside an archive. The new
2930 implementation is significantly faster and can be wrapped in a
2931 ``io.BufferedReader`` object for more speedups. It also solves an issue
2932 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00002943- Issue #7748: Since unicode values are supported for some metadata options in
2944 Distutils, the DistributionMetadata get_* methods will now return an utf-8
2945 encoded string for them. This ensures that the upload and register commands
2946 send the correct values to PyPI without any error.

3021-----------------
3022
Georg Brandlba83f822010-03-14 09:50:54 +00003023- The ``__complex__()`` method is now looked up on the class of instances to
3024 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00003025
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00003026- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
3027 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
3028
Mark Dickinson1b34d252010-01-01 17:27:30 +00003029- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00003030 DeprecationWarning when passed a float argument where an integer was expected.
3031 These functions and methods now raise TypeError instead. The majority of the
3032 effects of this change are in the extension modules, but some core functions
3033 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3034 and many unicode/str methods.
Mark Dickinson1b34d252010-01-01 17:27:30 +00003035

Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +00003044- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
3045 used to drop the time part of the result.
3046
Georg Brandlba83f822010-03-14 09:50:54 +00003047- Issue #1811: Improve accuracy and cross-platform consistency for true division
3048 of integers: the result of a/b is now correctly rounded for ints a and b (at
3049 least on IEEE 754 platforms), and in particular does not depend on the
3050 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +00003051
Georg Brandlba83f822010-03-14 09:50:54 +00003052- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
3053 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
3054 in the subclass.

Ronald Oussoren92919a62009-12-24 13:30:58 +00003057 executables on OSX.
3058
Georg Brandlba83f822010-03-14 09:50:54 +00003059 These executables now work properly with the arch(1) command: ``arch -ppc
3060 python`` will start a universal binary version of python in PPC mode (unlike
3061 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +00003062
Georg Brandlba83f822010-03-14 09:50:54 +00003063- Issue #1680159: Unicode coercion during an 'in' operation no longer masks the
3064 underlying error when the coercion fails for the left hand operand.

Antoine Pitrou80157252010-01-08 19:20:17 +00003083- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
Georg Brandlba83f822010-03-14 09:50:54 +00003084 renaming of `cPickle` to `pickle`. The warning was annoying since there's no
3085 alternative to cPickle if you care about performance. Patch by Florent

3121 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
3122 the same as passing no argument.
3123
Georg Brandlba83f822010-03-14 09:50:54 +00003124- Issue #7348: ``StringIO.StringIO.readline(-1)`` now acts as if it got no

Georg Brandlba83f822010-03-14 09:50:54 +00003146- Issue #5080: The argument parsing functions ``PyArg_ParseTuple()``,
3147 ``PyArg_ParseTupleAndKeywords()``, ``PyArg_VaParse()``,
3148 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept

Georg Brandlba83f822010-03-14 09:50:54 +00003217- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3218 decimal string that's guaranteed to round back to x under correct rounding
3219 (with round-half-to-even rounding mode). Previously it gave a string based on
3220 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3221 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3222 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003223
Georg Brandlba83f822010-03-14 09:50:54 +00003224- Issue #7117: On almost all platforms: float-to-string and string-to-float
3225 conversions within Python are now correctly rounded. Places these conversions
3226 occur include: str for floats and complex numbers; the float and complex
3227 constructors; old-style and new-style numeric formatting; serialization and
3228 deserialization of floats and complex numbers using marshal, pickle and json;
3229 parsing of float and imaginary literals in Python code; Decimal-to-float
3230 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003231
Georg Brandlba83f822010-03-14 09:50:54 +00003232 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3233 providing correctly-rounded strtod and dtoa C functions. This code is
3234 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3235 the C compiler. There may be a small number of platforms on which correct
3236 operation of this code cannot be guaranteed, so the code is not used: notably,
3237 this applies to platforms where the C double format is not IEEE 754 binary64,
3238 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3239 and Python's configure script is unable to determine how to change the FPU
3240 precision. On these platforms conversions use the platform strtod and dtoa,
3241 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003242
Georg Brandlba83f822010-03-14 09:50:54 +00003243- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3244 uses the correctly-rounded string <-> float conversions described above (when
3245 available), and so produces correctly rounded results that will display nicely
3246 under the float repr. There are two related small changes: (1) round now
3247 accepts any class with an ``__index__()`` method for its second argument (but
3248 no longer accepts floats for the second argument), and (2) an excessively
3249 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3250 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00003468 untrackable objects are not tracked by the garbage collector. This can reduce
3469 the size of collections and therefore the garbage collection overhead on
3470 long-running programs, depending on their particular use of datatypes.

Georg Brandlba83f822010-03-14 09:50:54 +00003476- Issue #4258: Make it possible to use base 2**30 instead of base 2**15 for the
3477 internal representation of integers, for performance reasons. Base 2**30 is
3478 enabled by default on 64-bit machines. Add --enable-big-digits option to
3479 configure, which overrides the default. Add sys.long_info structseq to
3480 provide information about the internal format.

Georg Brandlba83f822010-03-14 09:50:54 +00003543- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
3544 existing .py counterpart, override the co_filename attributes of all code
3545 objects if the original filename is obsolete (which can happen if the file has

3600
Georg Brandlba83f822010-03-14 09:50:54 +00003601- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
3602 file objects with closefd=False. The file descriptor is still kept open but
3603 the file object behaves like a closed file. The ``FileIO`` object also got a
3604 new readonly attribute ``closefd``.

Georg Brandlba83f822010-03-14 09:50:54 +00003627- On windows, ``os.chdir()`` given unicode was not working if
3628 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
3629 this code path is really executed because I cannot move to such directory on
3630 win2k)

Georg Brandlba83f822010-03-14 09:50:54 +00003632- Issue #4069: When ``set.remove(element)`` is used with a set element, the
3633 element is temporarily replaced with an equivalent frozenset. But the
3634 eventual KeyError would always report the empty ``frozenset()`` as the missing
3635 key. Now it correctly refers to the initial element.

3656 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
3657 step. This avoids problems with counting UTF-8 bytes that ignores the effect

3659
Walter Dörwald726ba8e2009-05-06 14:32:35 +00003660- Issue #3739: The unicode-internal encoder now reports the number of characters

4832 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
4833 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
4834 neither __int__ nor __long__, TypeError used to be raised (with a
4835 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
4836 struct.error in other cases.

4839 argument with an __int__ method can be packed, but use of this feature

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005033- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

5035 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5036 ``printf`` function, whereas PyString_FromFormat has an independent

Brett Cannon1eaf0742008-09-02 01:25:16 +00005134 warnings.catch_warnings() along with some API cleanup. Expanding the tests
5135 for catch_warnings() also led to an improvement in the raising of a
5136 DeprecationWarning related to warnings.warn_explicit().
5137

5160
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00005161- Issue #2975: When compiling several extension modules with Visual Studio 2008
5162 from the same python interpreter, some environment variables would grow
5163 without limit.
5164
Benjamin Peterson37346b22008-08-23 20:27:43 +00005165- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005202What's New in Python 2.6 beta 3?
5203================================
5204
Barry Warsaw07a4a382008-08-21 01:15:08 +00005205*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005206
5207Core and Builtins
5208-----------------
5209
Guido van Rossumf8402962008-08-20 15:01:50 +00005210- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5211 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5212 extensions do not automatically benefit from the class attribute
5213 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5214 to their tp_flags field if they care. This is a backwards
5215 compatibility feature; in 3.0, all types will use the cache by
5216 default.
5217
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005218- Keyword arguments can now follow starred arguments. (``f(a, *args,
5219 keyword=23)`` is now valid syntax.)
5220
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005221- ctypes function pointers that are COM methods have a boolean True
5222 value again.
5223
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005224- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5225 by denying s# to parse objects that have a releasebuffer procedure,
5226 and introducing s*.
5227
Georg Brandl1e13ea92008-08-11 09:07:59 +00005228- Issue #3537: Fix an assertion failure when an empty but presized dict
5229 object was stored in the freelist.
5230
Mark Dickinsonb6467572008-08-04 21:30:09 +00005231- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5232 ValueError consistently across platforms.
5233
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005234- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5235 (64bit Unix, for example), unichr() would truncate its argument and return
5236 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5237
Neal Norwitze7d8be82008-07-31 17:17:14 +00005238- Apply security patches from Apple.
5239
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005240- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5241 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5242
Antoine Pitrou92f82162008-07-25 22:22:08 +00005243- Issue #1819: function calls with several named parameters are now on
5244 average 35% faster (as measured by pybench).
5245
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005246- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5247 the python debugger steps into a class statement: the free variables (local
5248 variables defined in an outer scope) would be deleted from the outer scope.
5249
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005250- Issue #2620: Overflow checking when allocating or reallocating memory
5251 was not always being done properly in some python types and extension
5252 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5253 all been updated to perform better checks and places in the code that
5254 would previously leak memory on the error path when such an allocation
5255 failed have been fixed.

5258-------
5259
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00005260- Issue #3612: Added some missing basic types in ctypes.wintypes.
5261
Benjamin Petersone977ad42008-08-20 01:42:01 +00005262- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5263 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5264
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005265- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5266 version reported by these tools does not necessarily follow the python
5267 version numbering scheme, so the module is less strict when parsing it.
5268
Nick Coghlanf70385a2008-08-18 12:42:46 +00005269- Issue #2235: Added Py3k warnings for types which will become unhashable
5270 under the stricter __hash__ inheritance rules in 3.0. Several types
5271 which did not meet the rules for hash invariants and were already
5272 unhashable in 3.0 have now been explicitly flagged as unhashable in
5273 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5274 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5275
Brett Cannon88f801d2008-08-18 00:46:22 +00005276- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

5284
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005285- Issue #3575: Incremental decoder's decode function now takes bytearray
5286 by using 's*' instead of 't#'.
5287
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00005288- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00005289 fails unicode conversion on 2nd parameter. (windows only)
5290
Georg Brandl222e2082010-08-01 22:27:39 +00005291- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00005292 in a redirect.
5293

Brett Cannon721b1452008-08-16 22:00:27 +00005295 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00005296
Facundo Batistaeb90b782008-08-16 14:44:07 +00005297- Issue #2776: fixed small issue when handling an URL with double slash
5298 after a 302 response in the case of not going through a proxy.
5299
Antoine Pitroub90a8be2008-08-15 21:03:21 +00005300- Issue #2676: in the email package, content-type parsing was hanging on
5301 pathological input because of quadratic or exponential behaviour of a
5302 regular expression.
5303
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00005304- Issue #3476: binary buffered reading through the new "io" library is now
5305 thread-safe.
5306
Brett Cannonbf3157b2008-08-14 05:00:03 +00005307- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5308 since mimetools itself is deprecated. Because modules are cached, all
5309 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5310
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00005311- Issue #3134: shutil referenced undefined WindowsError symbol.
5312
Robert Schuppenies14646332008-08-10 11:01:53 +00005313- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
5314 menu entries were not deleted.
5315
Brett Cannon83e81842008-08-09 23:30:55 +00005316- Copied the implementation of reduce() to _functools.reduce() to have a
5317 version that did not raise a DeprecationWarning under -3.
5318
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00005319- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
5320 a MemoryError rather than silently stop the iteration.
5321
Guido van Rossum59ce9012008-08-09 14:55:34 +00005322- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5323 to _sre.compile() will now be rejected. This should not affect anybody
5324 since the re.compile() function never generates invalid re-bytecode.
5325
Skip Montanaroa032bf42008-08-08 22:52:51 +00005326- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5327 upon first access it can be automatically initialized from the csv file if
5328 it wasn't initialized during instantiation.
5329
Brett Cannon3aa2a492008-08-06 22:28:09 +00005330- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5331 the reload() built-in has been removed.
5332
Brett Cannon7e30b672008-08-04 21:52:25 +00005333- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00005334 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00005345 asking for a specific length. This problem only affected files opened
5346 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00005347

5392 regarding lack of coverage of new-style classes have also been
5393 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00005396What's New in Python 2.6 beta 2?
5397================================
5398
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005399*Release date: 17-Jul-2008*
5400
Raymond Hettingere3ae6552008-06-20 04:18:15 +00005401Core and Builtins
5402-----------------
5403
Georg Brandl3e483f62008-07-16 22:57:41 +00005404- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5405 its methods now allow for items objects that can be converted to
5406 an integer using operator.index().
5407
Mark Dickinson64b7e502008-07-16 09:40:03 +00005408- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5409 produced a ValueError instead of giving the correct float.
5410
Eric Smitha5fa5a22008-07-16 00:11:49 +00005411- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5412 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5413
Mark Dickinson7103aa42008-07-15 19:08:33 +00005414- Issue #3008: the float type has a new instance method 'float.hex'
5415 and a new class method 'float.fromhex' to convert floating-point
5416 numbers to and from hexadecimal strings, respectively.
5417
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005418- Issue #2235: __hash__ is once again inherited by default. To allow
5419 collections.Hashable to remain meaningful in the presence of the
5420 default hash implementation (object.__hash__), it is now possible
5421 to explicit block inheritance of hash by setting __hash__=None at
5422 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5423 level.
5424
Nick Coghlanb028f502008-07-13 14:52:36 +00005425- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5426 the parent module cannot be found while performing an absolute import.
5427 This means that an incorrectly defined __package__ attribute will
5428 now only prevent relative imports in that module rather than causing
5429 all imports from that module to fail.
5430
Nick Coghlan14ff9942008-07-08 14:21:42 +00005431- Issue #2517: Allow unicode messages in Exceptions again by correctly
5432 bypassing the instance dictionary when looking up __unicode__ on
5433 new-style classes.
5434
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00005435- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
5436 set to a custom object whose write() method happens to install
5437 another file in sys.stdout.
5438
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00005439- Issue #3088: Corrected a race condition in classes derived from
5440 threading.local: the first member set by a thread could be saved in
5441 another thread's dictionary.
5442
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005443- Issue #3004: Minor change to slice.indices(): the start and stop
5444 arguments are now treated identically, making the behaviour easier
5445 to describe and understand. For example, slice(None, -10,
5446 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5447 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5448 10, -1).
5449
Georg Brandl278fc502008-07-19 12:46:12 +00005450- Issue #3219: Calling a function with repeated keyword arguments,
5451 f(a=2, a=23), would not cause a syntax error. This was a regression
5452 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00005453
Georg Brandl278fc502008-07-19 12:46:12 +00005454- Issue #2862: Make int and float freelist management consistent with
5455 other freelists. Changes their CompactFreeList apis into
5456 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00005457
Brett Cannon8bb8fa52008-07-02 01:57:08 +00005458Library
5459-------
5460
Thomas Heller57adf222008-08-14 19:10:48 +00005461- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
5462 api functions without holding the GIL, which could lead to a fatal
5463 error when they failed.
5464
Martin v. Löwisaabf4042008-08-02 07:20:25 +00005465- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.
5466
Jesse Noller7fb96402008-07-17 21:01:05 +00005467- Issue #3395: fix reference in test_multiprocessing to old debugInfo method

5472
Jesse Noller13e9d582008-07-16 14:32:36 +00005473- Issue #3125: Remove copy_reg in multiprocessing and replace it with
5474 ForkingPickler.register() to resolve conflict with ctypes.
5475
Vinay Sajip51e65192008-07-18 09:01:10 +00005476- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00005477
Thomas Heller880f5292008-07-15 19:39:38 +00005478- Issue #3313: Fixed a crash when a failed dlopen() call does not set
5479 a valid dlerror() message.
5480
Thomas Heller2bad6572008-07-15 17:19:50 +00005481- Issue #3258: Fixed a crash when a ctypes POINTER type to an
5482 incomplete structure was created.
5483
Brett Cannon3d0b9f02008-07-13 01:15:07 +00005484- Issue #3339: dummy_thread.acquire() should not return None.
5485
Raymond Hettingerb01713e2008-07-10 14:34:57 +00005486- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
5487
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005488- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00005489
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005490- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
5491 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005492 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005493 content-length. The problem had been corrected in the 2.4 branch, but never
5494 merged into trunk.
5495
Georg Brandle78fbcc2008-07-05 10:13:36 +00005496- Issue #2663: add filtering capability to shutil.copytree().
5497

5499
5500- Issue #1526: Allow more than 64k files to be added to Zip64 file.
5501
5502- Issue #1746: Correct handling of zipfile archive comments (previously
5503 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00005504 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00005505
Vinay Sajip51e65192008-07-18 09:01:10 +00005506- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005507 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00005508
Nick Coghlanc060b0e2008-07-02 13:09:19 +00005509- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
5510 handling is now the same as that of other special attributes like __name__).
5511
Brett Cannon8bb8fa52008-07-02 01:57:08 +00005512- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
5513 removal in Python 3.0 in favor of urllib2.urlopen().

Gregory P. Smithc4691ec2008-07-07 05:09:12 +00005522- Issue #3094: httplib.HTTPSConnection Host: headers no longer include the
5523 redundant ":443" port number designation when the connection is using the

5525
Gregory P. Smithdb3409c2008-07-17 03:13:05 +00005526- Issue #874900: after an os.fork() call the threading module state is cleaned

Georg Brandl3ee81df2008-05-17 18:14:43 +00005964- Issue #1631171: Re-implement the 'warnings' module in C (the
5965 original Python code has been kept as backup). This will allow for
5966 using the 'warning's machinery in such places as the parser where
5967 use of pure Python code is not possible. Both the ``showarning()``
5968 and ``formatwarning()`` gain an optional 'line' argument which is
5969 not called by default for backwards-compatibility reasons. Setting
5970 ``warnings.showwarning()`` to an implementation that lacks support
5971 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006034- Issue #2550: The approach used by client/server code for obtaining
6035 ports to listen on in network-oriented tests has been refined in an
6036 effort to facilitate running multiple instances of the entire
6037 regression test suite in parallel without issue.
6038 test_support.bind_port() has been fixed such that it will always
6039 return a unique port -- which wasn't always the case with the
6040 previous implementation, especially if socket options had been set
6041 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6042 new implementation of bind_port() will actually raise an exception
6043 if it is passed an AF_INET/SOCK_STREAM socket with either the
6044 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6045 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6046 the socket it's been passed. This currently only applies to
6047 Windows. This option prevents any other sockets from binding to the
6048 host/port we've bound to, thus removing the possibility of the
6049 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6050 when a second SOCK_STREAM socket binds and accepts to a host/port
6051 that's already been bound by another socket. The optional preferred
6052 port parameter to bind_port() has been removed. Under no
6053 circumstances should tests be hard coding ports!
6054
6055 test_support.find_unused_port() has also been introduced, which will
6056 pass a temporary socket object to bind_port() in order to obtain an
6057 unused port. The temporary socket object is then closed and
6058 deleted, and the port is returned. This method should only be used
6059 for obtaining an unused port in order to pass to an external program
6060 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6061 a parameter to a server-oriented class that doesn't give you direct
6062 access to the underlying socket used.
6063
6064 Finally, test_support.HOST has been introduced, which should be used
6065 for the host argument of any relevant socket calls (i.e. bind and
6066 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006067
6068 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006069 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006070 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6071 test_asynchat and test_socket_ssl.
6072
Georg Brandl3ee81df2008-05-17 18:14:43 +00006073 It is now possible for multiple instances of the regression test
6074 suite to run in parallel without issue.

6230 processor information on Windows XP and later. As a result,
Marc-André Lemburga1867752008-03-20 18:08:00 +00006231 platform.machine() and platform.processor() will report this
6232 information as well.

Eric Smitha73fbe72008-02-23 03:09:44 +00006353- Added the future_builtins module, which contains hex() and oct().
6354 These are the PEP 3127 version of these functions, designed to be
6355 compatible with the hex() and oct() builtins from Python 3.0. They
6356 differ slightly in their output formats from the existing, unchanged
6357 Python 2.6 builtins. The expected usage of the future_builtins
6358 module is:
6359 from future_builtins import hex, oct
6360
Eric Smith7ef40bf2008-02-20 23:34:22 +00006361- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6362 exponents for exponents with absolute value < 100. Follows C99
6363 standard. This is a change on Windows, which would use 3 digits.
6364 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6365 so that any alterations it does to the resulting string will be
6366 available in stringlib/formatter.h (for float.__format__).
6367
Eric Smith5a3c1352008-02-19 13:21:56 +00006368- Implemented PEP 3101, Advanced String Formatting. This adds a new
6369 builtin format(); a format() method for str and unicode; a
6370 __format__() method to object, str, unicode, int, long, float, and
6371 datetime; the class string.Formatter; and the C API
6372 PyObject_Format().
6373
Georg Brandl3ee81df2008-05-17 18:14:43 +00006374- Fixed several potential crashes, all caused by specially crafted
6375 __del__ methods exploiting objects in temporarily inconsistent
6376 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006377
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006378- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006379 prevent a possible crash: an Abstract Base Class would try to access
6380 a slot on a registered virtual subclass.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006385- Clear all free lists during a gc.collect() of the highest generation
6386 in order to allow pymalloc to free more arenas. Python may give back
6387 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006388
Georg Brandl3ee81df2008-05-17 18:14:43 +00006389- Issue #2045: Fix an infinite recursion triggered when printing a
6390 subclass of collections.defaultdict, if its default_factory is set
6391 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006392
Christian Heimesf75dbef2008-02-08 00:11:31 +00006393- Fixed a minor memory leak in dictobject.c. The content of the free
6394 list was not freed on interpreter shutdown.
6395
Georg Brandl21e99f42010-03-07 15:23:59 +00006396- Limit free list of method and built-in function objects to 256

Christian Heimes6075a822008-02-06 12:44:34 +00006398
Georg Brandl3ee81df2008-05-17 18:14:43 +00006399- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6400 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006401 to compact the internal free lists of pre-allocted ints and floats.
6402
Georg Brandl3ee81df2008-05-17 18:14:43 +00006403- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6404 calls. Python expected the return type int but the fork familie
6405 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006406

Georg Brandl3ee81df2008-05-17 18:14:43 +00006419- Patch #1473257: generator objects gain a gi_code attribute. This is
6420 the same object as the func_code attribute of the function that
6421 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006422
Georg Brandl3ee81df2008-05-17 18:14:43 +00006423- Issue #1920: "while 0" statements were completely removed by the
6424 compiler, even in the presence of an "else" clause, which is
6425 supposed to be run when the condition is false. Now the compiler
6426 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006427
Guido van Rossumeead05f2008-01-24 18:21:02 +00006428- A few crashers fixed: weakref_in_del.py (issue #1377858);
6429 loosing_dict_ref.py (issue #1303614, test67.py);
6430 borrowed_ref_[34].py (not in tracker).
6431

6435
Georg Brandl3ee81df2008-05-17 18:14:43 +00006436- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006437 several extension methods and modules do not work without unicode
6438 support.
6439
Georg Brandl26543b12008-01-21 18:36:51 +00006440- Issue #1882: when compiling code from a string, encoding cookies in the

6442
Georg Brandl14404b62008-01-19 19:27:05 +00006443- Issue #1679: "0x" was taken as a valid integer literal.
6444
Georg Brandl6caad7d2008-01-26 14:19:22 +00006445- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006446 added.
6447
Christian Heimesc94e2b52008-01-14 04:13:37 +00006448- sys.float_info / PyFloat_GetInfo: The floating point information
6449 object was converted from a dict to a specialized structseq object.
6450
Georg Brandl3ee81df2008-05-17 18:14:43 +00006451- Patch #1816: Added sys.flags structseq. It exposes the status of
6452 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006453
Georg Brandl3ee81df2008-05-17 18:14:43 +00006454- Objects/structseq.c: Implemented new structseq representation. The
6455 patch makes structseqs (e.g. the return value of os.stat) more
6456 readable.

6465
Georg Brandl3ee81df2008-05-17 18:14:43 +00006466- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
6467 envvar and sys.dont_write_bytecode attribute. All these can be set
6468 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006469
Georg Brandl3ee81df2008-05-17 18:14:43 +00006470- Improve some exception messages when Windows fails to load an
6471 extension module. Now we get for example '%1 is not a valid Win32
6472 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00006479- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006480 and INF. float("nan"), float("inf") and float("-inf") now work on
6481 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006483- Compiler now generates simpler and faster code for dictionary
6484 literals. The oparg for BUILD_MAP now indicates an estimated
6485 dictionary size. There is a new opcode, STORE_MAP, for adding
6486 entries to the dictionary.

6516 file can now be directly executed by passing their name to the
6517 interpreter. The directory/zipfile is automatically inserted as the
6518 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006520- Issue #1265: Fix a problem with sys.settrace, if the tracing
6521 function uses a generator expression when at the same time the
6522 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006523
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006524- sets and frozensets now have an isdisjoint() method.

6529
Georg Brandl21e99f42010-03-07 15:23:59 +00006530- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006531 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6532 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006533
Georg Brandl3ee81df2008-05-17 18:14:43 +00006534- Issue #1686386: Tuple's tp_repr did not take into account the
6535 possibility of having a self-referential tuple, which is possible
6536 from C code. Nor did object's tp_str consider that a type's tp_str
6537 could do something that could lead to an inifinite recursion.
6538 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6539 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006540
Georg Brandl3ee81df2008-05-17 18:14:43 +00006541- Issue #1164: It was possible to trigger deadlock when using the
6542 'print' statement to write to a file since the GIL was not released
6543 as needed. Now PyObject_Print() does the right thing along with
6544 various tp_print implementations of the built-in types and those in
6545 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006546
Georg Brandl3ee81df2008-05-17 18:14:43 +00006547- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannona0c05512007-09-10 21:38:27 +00006553
Brett Cannon1e534b52007-09-07 04:18:30 +00006554- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006555 PyObject_Call() never calling back out to Python code to trigger
6556 recursion depth updates/checks. Required the creation of a static
6557 RuntimeError instance in case normalizing an exception put the
6558 recursion check value past its limit. Fixes crashers
6559 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00006560

Neal Norwitz0ac60192007-05-27 04:08:54 +00006574- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006575 __*__ attributes. (Some already existed, e.g., __doc__ and
6576 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006577
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00006578- Add -3 option to the interpreter to warn about features that are
6579 deprecated and will be changed/removed in Python 3.0.
6580
Georg Brandl2134e752007-05-21 20:34:16 +00006581- Patch #1686487: you can now pass any mapping after '**' in function
6582 calls.
6583
Collin Winter62903052007-05-18 23:11:24 +00006584- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006585 "except E as target:". This is to provide forwards compatibility
6586 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00006593- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006594 setting a plain string, ie don't expand to single letter identifiers.
6595
Raymond Hettinger13936692007-04-11 18:40:58 +00006596- Request #1191699: Slices can now be pickled.
6597
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006598- Request #1193128: str.translate() now allows a None argument for
6599 translations that only remove characters without re-mapping the
6600 remaining characters.
6601
Georg Brandl5cb76c12007-03-21 09:00:39 +00006602- Patch #1682205: a TypeError while unpacking an iterable is no longer

6606
Guido van Rossum143b5642007-03-23 04:58:42 +00006607- Bug #1683368: The object.__init__() and object.__new__() methods are
6608 now stricter in rejecting excess arguments. The only time when
6609 either allows excess arguments is when it is not overridden and the
6610 other one is. For backwards compatibility, when both are
6611 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006612 warning later). Also, type.__init__() insists on the same signature
6613 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00006614
Georg Brandl3ee81df2008-05-17 18:14:43 +00006615- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6616 object to complex using its __complex__() method before falling back
6617 to the __float__() method. Therefore, the functions in the cmath
6618 module now can operate on objects that define a __complex__()
6619 method.

6623 same slot names.

6630 its type.

6636
Georg Brandl7b9c5552007-03-12 14:30:05 +00006637- Bug #1678647: write a newline after printing an exception in any
6638 case, even when converting the value to a string failed.
6639
Georg Brandl871f1bc2007-03-12 13:17:36 +00006640- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006641 its argument, if it exists. If not, it will work like before. This
6642 allows customizing the output of dir() in the presence of a
6643 __getattr__().

6647
Georg Brandl3ee81df2008-05-17 18:14:43 +00006648- Patch #1675981: remove unreachable code from ``type.__new__()``

6652 parthensized forms. This means complex(repr(x)) now works instead of
6653 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006654
Georg Brandlaa2321b2007-03-07 00:40:28 +00006655- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006656 makes the filenames the warning module prints much more sensible
6657 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00006658

Georg Brandl0fca97a2007-03-05 22:28:08 +00006670- Patch #1674228: when assigning a slice (old-style), check for the
6671 sq_ass_slice instead of the sq_slice slot.
6672
Georg Brandl3ee81df2008-05-17 18:14:43 +00006673- When printing an unraisable error, don't print exceptions. before
6674 the name. This duplicates the behavior whening normally printing
6675 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007208 AttributeError instead of an IOError when the server's response

Georg Brandlf66b6032007-03-14 08:27:52 +00007210

Georg Brandl3ee81df2008-05-17 18:14:43 +00007243 are set for invalid interpolation sequences that would lead to
7244 errors on reading back those values.

7300 TestCase and TestSuite subclasses (not instances) are no longer
7301 accepted in TestSuite.addTest(). This should cause no

7303 -- the failure just occurred later, with a more cumbersome
7304 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007693 time so that opening a database previously created with the DB_DUP
7694 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7695 opens. Specifically: dictionary assignment to a DB object will
7696 replace all values for a given key when the database allows
7697 duplicate values. DB users should use DB.put(k, v) when they want
7698 to store duplicates; not DB[k] = v.

7707 behavior of quoting dots if they are the second character of any
7708 line.

8054 of w# format code incorrectly truncated the length to an int, even
8055 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
8056 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008086- Added case insensitive comparison methods ``PyOS_stricmp(char*,
8087 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
