Ned Deily87e82bb2011-06-28 19:52:59 -0700114- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
115 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
116 interpreter process. This could cause failures in non-Distutils subprocesses
117 and was unreliable since tests or user programs could modify the interpreter
118 environment after Distutils set it. Instead, have Distutils set the the
119 deployment target only in the environment of each build subprocess. It is
120 still possible to globally override the default by setting
121 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
122 greater or equal to the default value, the value with which the interpreter
123 was built.

132 times without error, and _ProxyFile now closes the wrapped file.
133
Victor Stinnerc74a6ba2011-06-17 14:06:27 +0200134- Issue #12133: AbstractHTTPHandler.do_open() of urllib.request closes the HTTP
135 connection if its getresponse() method fails with a socket error. Patch
136 written by Ezio Melotti.
137
Benjamin Peterson0eb4ac42011-06-11 15:53:11 -0500138- Issue #9284: Allow inspect.findsource() to find the source of doctest
139 functions.
140

150
Barry Warsawc5643282011-07-19 17:06:30 -0400151- sys.setcheckinterval() now updates the current ticker count as well as
152 updating the check interval, so if the user decreases the check interval,
153 the ticker doesn't have to wind down to zero from the old starting point
154 before the new interval takes effect. And if the user increases the
155 interval, it makes sure the new limit takes effect right away rather have an
156 early task switch before recognizing the new interval.
Raymond Hettinger19b851d2011-06-01 18:21:42 -0700157
Victor Stinner776e69b2011-06-01 01:03:00 +0200158- Issue #12085: Fix an attribute error in subprocess.Popen destructor if the

1010
Raymond Hettinger20397532010-09-12 02:11:45 +00001011- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
1012 This prevents user-created self-referencing ordered dictionaries from
1013 becoming permanently uncollectable GC garbage. The downside is that
1014 removing __del__ means that the internal doubly-linked list has to wait for
1015 GC collection rather than freeing memory immediately when the refcnt drops
1016 to zero.
1017
Raymond Hettingerffd2a422010-09-10 10:47:22 +00001018- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently

1021
Antoine Pitrouc818ed42010-09-07 21:40:25 +00001022- Issue #9792: In case of connection failure, socket.create_connection()
1023 would swallow the exception and raise a new one, making it impossible
1024 to fetch the original errno, or to filter timeout errors. Now the
1025 original error is re-raised.
1026
Antoine Pitrouf4f61712010-09-07 16:34:47 +00001027- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,

1046
R. David Murray7c4bf552010-08-25 01:45:57 +00001047- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
1048 character years even if the message contains RFC822 two character years.
1049
Daniel Stutzbach91287322010-08-24 21:09:30 +00001050- Issue #8750: Fixed MutableSet's methods to correctly handle

1063
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00001064- Issue #9617: Signals received during a low-level write operation aren't
1065 ignored by the buffered IO layer anymore.
1066
Benjamin Peterson52c36052010-08-21 03:03:22 +00001067- Issue #2521: Use weakrefs on for caching in the abc module, so that classes

1069
Raymond Hettingera54b2da2010-08-17 19:03:06 +00001070- Issue #9626: the view methods for collections.OrderedDict() were returning

1075 comment indicating they are generated. Manually maintained MANIFESTs
1076 without this marker will not be overwritten or removed.
1077
Antoine Pitroue1436d12010-08-12 15:25:51 +00001078- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
1079 and a BadZipfile error is raised if it doesn't match (as used to be the
1080 case in Python 2.5 and earlier).
1081
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00001082- Issue #9550: a BufferedReader could issue an additional read when the
1083 original read request had been satisfied, which could block indefinitely
1084 when the underlying raw IO channel was e.g. a socket. Report and original
1085 patch by Jason V. Miller.
1086
Fred Drake0a1fa0e2010-08-10 13:09:54 +00001087- Issue #9551: Don't raise TypeError when setting the value to None for

Senthil Kumarane677ecf2010-08-08 11:56:31 +00001105- Fix Issue8280 - urllib2's Request method will remove fragements in the url.
1106 This is how it is supposed to work, wget and curl do the same. Previous
1107 behavior was wrong.

Georg Brandlfee0f442010-05-22 21:26:21 +00001735- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown, where
1736 the method could block indefinitely if called just before the event loop
1737 started running. This also fixes the occasional freezes witnessed in
1738 test_httpservers.

Antoine Pitroufc69af12010-04-24 20:04:58 +00001740- Issue #5103: SSL handshake would ignore the socket timeout and block
1741 indefinitely if the other end didn't respond.
1742
Georg Brandlfee0f442010-05-22 21:26:21 +00001743- The do_handshake() method of SSL objects now adjusts the blocking mode of the
1744 SSL structure if necessary (as other methods already do).

Georg Brandlfee0f442010-05-22 21:26:21 +00001754- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of the
1755 string "python" as the *ident*. openlog() arguments are all optional and
1756 keywords.

Philip Jenveyaebbaeb2010-04-06 23:24:45 +00001861- Issue #7301: Add environment variable $PYTHONWARNINGS.
1862
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00001863- Issue #8329: Don't return the same lists from select.select when no fds are
1864 changed.
1865
Georg Brandlfee0f442010-05-22 21:26:21 +00001866- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00001867 on 64-bit machines. The shift count for either left or right shift is
1868 permitted to be up to sys.maxsize.

Georg Brandlfee0f442010-05-22 21:26:21 +00001876- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1877 with a non-empty format string. This is an effort to future-proof user
1878 code. If a derived class does not currently implement __format__ but later
1879 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00001880 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00001881 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00001914- Issue #8257: The Decimal construct now accepts a float instance directly,

Georg Brandlfee0f442010-05-22 21:26:21 +00001931- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1932 InvalidOperation instead of returning False. (Comparisons involving a quiet
1933 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1934 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00001935
Georg Brandlfee0f442010-05-22 21:26:21 +00001936- Issue #2531: Comparison operations between floats and Decimal instances now
1937 return a result based on the numeric values of the operands; previously they
1938 returned an arbitrary result based on the relative ordering of id(float) and
1939 id(Decimal).

Georg Brandlfee0f442010-05-22 21:26:21 +00001942 argument `-` which tells it to read files to compile from stdin. Each line is
1943 read on demand and the named file is compiled immediately. (Original patch by

Georg Brandlfee0f442010-05-22 21:26:21 +00001953- Comparisons using one of <, <=, >, >= between a complex instance and a
1954 Fractions instance now raise TypeError instead of returning True/False. This
1955 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1956 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00002374 file position when calling `truncate()`. It would previously change the file
2375 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002376 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

2379 class used to represent files stored inside an archive. The new
2380 implementation is significantly faster and can be wrapped in a

2382 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

2472
Georg Brandlba83f822010-03-14 09:50:54 +00002473- The ``__complex__()`` method is now looked up on the class of instances to
2474 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00002475
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00002476- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
2477 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
2478
Mark Dickinson1b34d252010-01-01 17:27:30 +00002479- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00002480 DeprecationWarning when passed a float argument where an integer was expected.
2481 These functions and methods now raise TypeError instead. The majority of the
2482 effects of this change are in the extension modules, but some core functions
2483 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2484 and many unicode/str methods.

2495 used to drop the time part of the result.
2496
Georg Brandlba83f822010-03-14 09:50:54 +00002497- Issue #1811: Improve accuracy and cross-platform consistency for true division
2498 of integers: the result of a/b is now correctly rounded for ints a and b (at
2499 least on IEEE 754 platforms), and in particular does not depend on the
2500 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +00002501
Georg Brandlba83f822010-03-14 09:50:54 +00002502- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
2503 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
2504 in the subclass.

Ronald Oussoren92919a62009-12-24 13:30:58 +00002507 executables on OSX.
2508
Georg Brandlba83f822010-03-14 09:50:54 +00002509 These executables now work properly with the arch(1) command: ``arch -ppc
2510 python`` will start a universal binary version of python in PPC mode (unlike
2511 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +00002534 renaming of `cPickle` to `pickle`. The warning was annoying since there's no

2668 decimal string that's guaranteed to round back to x under correct rounding
2669 (with round-half-to-even rounding mode). Previously it gave a string based on

Georg Brandlba83f822010-03-14 09:50:54 +00002682 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2683 providing correctly-rounded strtod and dtoa C functions. This code is
2684 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2685 the C compiler. There may be a small number of platforms on which correct
2686 operation of this code cannot be guaranteed, so the code is not used: notably,
2687 this applies to platforms where the C double format is not IEEE 754 binary64,
2688 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2689 and Python's configure script is unable to determine how to change the FPU
2690 precision. On these platforms conversions use the platform strtod and dtoa,
2691 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00002693- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2694 uses the correctly-rounded string <-> float conversions described above (when
2695 available), and so produces correctly rounded results that will display nicely
2696 under the float repr. There are two related small changes: (1) round now
2697 accepts any class with an ``__index__()`` method for its second argument (but
2698 no longer accepts floats for the second argument), and (2) an excessively
2699 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2700 raises an exception.

Antoine Pitrouf8387af2009-03-23 18:41:45 +00002917- Issue #4688: Add a heuristic so that tuples and dicts containing only
Georg Brandlba83f822010-03-14 09:50:54 +00002918 untrackable objects are not tracked by the garbage collector. This can reduce
2919 the size of collections and therefore the garbage collection overhead on
2920 long-running programs, depending on their particular use of datatypes.

2927 internal representation of integers, for performance reasons. Base 2**30 is
2928 enabled by default on 64-bit machines. Add --enable-big-digits option to

2961
Georg Brandl29c6a282009-04-05 20:23:13 +00002962- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +00002963 were suppressing all exceptions. These include list(), filter(), map(),

2965
Benjamin Peterson596d3062009-01-19 15:42:23 +00002966- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os

Georg Brandlba83f822010-03-14 09:50:54 +00002974- Issue #4935: The overflow checking code in the expandtabs() method common to
2975 str, bytes and bytearray could be optimized away by the compiler, letting the
2976 interpreter segfault instead of raising an error.

2992
Georg Brandlba83f822010-03-14 09:50:54 +00002993- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
2994 existing .py counterpart, override the co_filename attributes of all code
2995 objects if the original filename is obsolete (which can happen if the file has
2996 been renamed, moved, or if it is accessed through different paths). Patch by

3037 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
3038 instances. On a typical machine this saves 3 bytes of memory (on average) per

3050
Georg Brandlba83f822010-03-14 09:50:54 +00003051- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
3052 file objects with closefd=False. The file descriptor is still kept open but
3053 the file object behaves like a closed file. The ``FileIO`` object also got a
3054 new readonly attribute ``closefd``.

3073
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00003074- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00003075 because it is a reserved word in 3.x.

Georg Brandlba83f822010-03-14 09:50:54 +00003077- On windows, ``os.chdir()`` given unicode was not working if
3078 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
3079 this code path is really executed because I cannot move to such directory on
3080 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00003081
Georg Brandlba83f822010-03-14 09:50:54 +00003082- Issue #4069: When ``set.remove(element)`` is used with a set element, the
3083 element is temporarily replaced with an equivalent frozenset. But the
3084 eventual KeyError would always report the empty ``frozenset()`` as the missing
3085 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00003105- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
3106 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
3107 step. This avoids problems with counting UTF-8 bytes that ignores the effect
3108 of using the replace error handler in PyUnicode_DecodeUTF8().
3109
Walter Dörwald726ba8e2009-05-06 14:32:35 +00003110- Issue #3739: The unicode-internal encoder now reports the number of characters

Georg Brandlba83f822010-03-14 09:50:54 +00003113- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

3115 gives improved memory leak detection when running under Valgrind, while taking
3116 advantage of pymalloc at other times.

Georg Brandlba83f822010-03-14 09:50:54 +00004277 - Packing a float now always gives a Deprecation Warning. Previously it
4278 only warned for 'I', 'L', '*B', '*H', '*I', '*L'.
Mark Dickinson463dc4b2009-07-05 10:01:24 +00004279
Georg Brandlba83f822010-03-14 09:50:54 +00004280 - If x is not an int, long or float, then packing x will always result in
4281 struct.error. Previously an x with an __int__ method could be packed by
4282 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
4283 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
4284 neither __int__ nor __long__, TypeError used to be raised (with a
4285 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
4286 struct.error in other cases.
Mark Dickinson463dc4b2009-07-05 10:01:24 +00004287
Georg Brandlba83f822010-03-14 09:50:54 +00004288 Note: as of Python 2.7 beta 1, the above is out of date. In 2.7 beta 1, any
4289 argument with an __int__ method can be packed, but use of this feature
4290 triggers a DeprecationWarning.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004483- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4484 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4485 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4486 ``printf`` function, whereas PyString_FromFormat has an independent
4487 implementation and uses "%zd" on all platforms for size_t values.
4488 This makes a difference on win64, where ``printf`` needs "%Id" to display
4489 64bit values.

Nick Coghland2e09382008-09-11 12:11:06 +00004557- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00004558 return a list or None rather than a custom object.
4559
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00004560- Issue #1638033: Cookie.Morsel gained the httponly attribute.

Brett Cannon1eaf0742008-09-02 01:25:16 +00004584 warnings.catch_warnings() along with some API cleanup. Expanding the tests
4585 for catch_warnings() also led to an improvement in the raising of a
4586 DeprecationWarning related to warnings.warn_explicit().
4587
Benjamin Peterson973e6c22008-09-01 23:12:58 +00004588- The deprecation warnings for the old camelCase threading API were removed.

4610
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00004611- Issue #2975: When compiling several extension modules with Visual Studio 2008
4612 from the same python interpreter, some environment variables would grow
4613 without limit.
4614
Benjamin Peterson37346b22008-08-23 20:27:43 +00004615- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
4616 exploitation of poor argument checking.
4617
Gerhard Häringef2276b2008-09-12 13:54:06 +00004618- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".
4619
Gerhard Häring6e1afcf2008-09-12 18:58:57 +00004620- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all

4631 wrapper for warnings.catch_warnings() that makes it easier to check
4632 that expected warning messages are being reported.
4633

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004652What's New in Python 2.6 beta 3?
4653================================
4654
Barry Warsaw07a4a382008-08-21 01:15:08 +00004655*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004656
4657Core and Builtins
4658-----------------
4659
Guido van Rossumf8402962008-08-20 15:01:50 +00004660- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4661 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4662 extensions do not automatically benefit from the class attribute
4663 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4664 to their tp_flags field if they care. This is a backwards
4665 compatibility feature; in 3.0, all types will use the cache by
4666 default.
4667
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004668- Keyword arguments can now follow starred arguments. (``f(a, *args,
4669 keyword=23)`` is now valid syntax.)
4670
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004671- ctypes function pointers that are COM methods have a boolean True
4672 value again.
4673
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004674- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4675 by denying s# to parse objects that have a releasebuffer procedure,
4676 and introducing s*.
4677
Georg Brandl1e13ea92008-08-11 09:07:59 +00004678- Issue #3537: Fix an assertion failure when an empty but presized dict
4679 object was stored in the freelist.
4680
Mark Dickinsonb6467572008-08-04 21:30:09 +00004681- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4682 ValueError consistently across platforms.
4683
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004684- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4685 (64bit Unix, for example), unichr() would truncate its argument and return
4686 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4687
Neal Norwitze7d8be82008-07-31 17:17:14 +00004688- Apply security patches from Apple.
4689
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004690- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4691 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4692
Antoine Pitrou92f82162008-07-25 22:22:08 +00004693- Issue #1819: function calls with several named parameters are now on
4694 average 35% faster (as measured by pybench).
4695
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004696- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4697 the python debugger steps into a class statement: the free variables (local
4698 variables defined in an outer scope) would be deleted from the outer scope.
4699
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004700- Issue #2620: Overflow checking when allocating or reallocating memory
4701 was not always being done properly in some python types and extension
4702 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4703 all been updated to perform better checks and places in the code that
4704 would previously leak memory on the error path when such an allocation
4705 failed have been fixed.

4708-------
4709
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00004710- Issue #3612: Added some missing basic types in ctypes.wintypes.
4711
Benjamin Petersone977ad42008-08-20 01:42:01 +00004712- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4713 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4714
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004715- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4716 version reported by these tools does not necessarily follow the python
4717 version numbering scheme, so the module is less strict when parsing it.
4718
Nick Coghlanf70385a2008-08-18 12:42:46 +00004719- Issue #2235: Added Py3k warnings for types which will become unhashable
4720 under the stricter __hash__ inheritance rules in 3.0. Several types
4721 which did not meet the rules for hash invariants and were already
4722 unhashable in 3.0 have now been explicitly flagged as unhashable in
4723 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4724 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4725
Brett Cannon88f801d2008-08-18 00:46:22 +00004726- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

4734
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004735- Issue #3575: Incremental decoder's decode function now takes bytearray
4736 by using 's*' instead of 't#'.
4737
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004738- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004739 fails unicode conversion on 2nd parameter. (windows only)
4740
Georg Brandl222e2082010-08-01 22:27:39 +00004741- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004742 in a redirect.
4743
Brett Cannonabe423e2008-08-16 21:47:07 +00004744- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00004745 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004746
Facundo Batistaeb90b782008-08-16 14:44:07 +00004747- Issue #2776: fixed small issue when handling an URL with double slash
4748 after a 302 response in the case of not going through a proxy.
4749
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004750- Issue #2676: in the email package, content-type parsing was hanging on
4751 pathological input because of quadratic or exponential behaviour of a
4752 regular expression.
4753
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004754- Issue #3476: binary buffered reading through the new "io" library is now
4755 thread-safe.
4756
Brett Cannonbf3157b2008-08-14 05:00:03 +00004757- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4758 since mimetools itself is deprecated. Because modules are cached, all
4759 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4760
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004761- Issue #3134: shutil referenced undefined WindowsError symbol.
4762
Robert Schuppenies14646332008-08-10 11:01:53 +00004763- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4764 menu entries were not deleted.
4765
Brett Cannon83e81842008-08-09 23:30:55 +00004766- Copied the implementation of reduce() to _functools.reduce() to have a
4767 version that did not raise a DeprecationWarning under -3.
4768
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004769- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4770 a MemoryError rather than silently stop the iteration.
4771
Guido van Rossum59ce9012008-08-09 14:55:34 +00004772- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4773 to _sre.compile() will now be rejected. This should not affect anybody
4774 since the re.compile() function never generates invalid re-bytecode.
4775
Skip Montanaroa032bf42008-08-08 22:52:51 +00004776- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4777 upon first access it can be automatically initialized from the csv file if
4778 it wasn't initialized during instantiation.
4779
Brett Cannon3aa2a492008-08-06 22:28:09 +00004780- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4781 the reload() built-in has been removed.
4782
Brett Cannon7e30b672008-08-04 21:52:25 +00004783- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00004784 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00004795 asking for a specific length. This problem only affected files opened
4796 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00004797

4822 file name rather than a ZipInfo instance, so files are extracted with
4823 mode 0600 rather than 000 under Unix.
4824
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00004825- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
4826 argument in python 2.5, this broke code that subclassed Popen to include its

4838 interaction with the tp_hash slot (added in 2.6b2) are now documented
4839
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00004840- Issue #643841: The language reference now provides more detailed
4841 coverage of the lookup process for special methods. The disclaimers
4842 regarding lack of coverage of new-style classes have also been
4843 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00004846What's New in Python 2.6 beta 2?
4847================================
4848
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004849*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00004851Core and Builtins
4852-----------------
4853
Georg Brandl3e483f62008-07-16 22:57:41 +00004854- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4855 its methods now allow for items objects that can be converted to
4856 an integer using operator.index().
4857
Mark Dickinson64b7e502008-07-16 09:40:03 +00004858- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4859 produced a ValueError instead of giving the correct float.
4860
Eric Smitha5fa5a22008-07-16 00:11:49 +00004861- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4862 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4863
Mark Dickinson7103aa42008-07-15 19:08:33 +00004864- Issue #3008: the float type has a new instance method 'float.hex'
4865 and a new class method 'float.fromhex' to convert floating-point
4866 numbers to and from hexadecimal strings, respectively.
4867
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004868- Issue #2235: __hash__ is once again inherited by default. To allow
4869 collections.Hashable to remain meaningful in the presence of the
4870 default hash implementation (object.__hash__), it is now possible
4871 to explicit block inheritance of hash by setting __hash__=None at
4872 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4873 level.
4874
Nick Coghlanb028f502008-07-13 14:52:36 +00004875- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4876 the parent module cannot be found while performing an absolute import.
4877 This means that an incorrectly defined __package__ attribute will
4878 now only prevent relative imports in that module rather than causing
4879 all imports from that module to fail.
4880
Nick Coghlan14ff9942008-07-08 14:21:42 +00004881- Issue #2517: Allow unicode messages in Exceptions again by correctly
4882 bypassing the instance dictionary when looking up __unicode__ on
4883 new-style classes.
4884
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00004885- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
4886 set to a custom object whose write() method happens to install
4887 another file in sys.stdout.
4888
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00004889- Issue #3088: Corrected a race condition in classes derived from
4890 threading.local: the first member set by a thread could be saved in
4891 another thread's dictionary.
4892
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004893- Issue #3004: Minor change to slice.indices(): the start and stop
4894 arguments are now treated identically, making the behaviour easier
4895 to describe and understand. For example, slice(None, -10,
4896 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4897 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4898 10, -1).
4899
Georg Brandl278fc502008-07-19 12:46:12 +00004900- Issue #3219: Calling a function with repeated keyword arguments,
4901 f(a=2, a=23), would not cause a syntax error. This was a regression
4902 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00004903
Georg Brandl278fc502008-07-19 12:46:12 +00004904- Issue #2862: Make int and float freelist management consistent with
4905 other freelists. Changes their CompactFreeList apis into
4906 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00004911- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
4912 api functions without holding the GIL, which could lead to a fatal
4913 error when they failed.
4914
Martin v. Löwisaabf4042008-08-02 07:20:25 +00004915- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

4924 ForkingPickler.register() to resolve conflict with ctypes.
4925
Vinay Sajip51e65192008-07-18 09:01:10 +00004926- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00004927
Thomas Heller880f5292008-07-15 19:39:38 +00004928- Issue #3313: Fixed a crash when a failed dlopen() call does not set
4929 a valid dlerror() message.
4930
Thomas Heller2bad6572008-07-15 17:19:50 +00004931- Issue #3258: Fixed a crash when a ctypes POINTER type to an
4932 incomplete structure was created.

4937
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004938- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00004939
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004940- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
4941 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004942 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004943 content-length. The problem had been corrected in the 2.4 branch, but never
4944 merged into trunk.
4945
Georg Brandle78fbcc2008-07-05 10:13:36 +00004946- Issue #2663: add filtering capability to shutil.copytree().

Facundo Batista66c52772008-07-02 16:52:55 +00004958
Nick Coghlanc060b0e2008-07-02 13:09:19 +00004959- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
4960 handling is now the same as that of other special attributes like __name__).
4961
Brett Cannon8bb8fa52008-07-02 01:57:08 +00004962- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
4963 removal in Python 3.0 in favor of urllib2.urlopen().

5415 original Python code has been kept as backup). This will allow for
5416 using the 'warning's machinery in such places as the parser where
5417 use of pure Python code is not possible. Both the ``showarning()``
5418 and ``formatwarning()`` gain an optional 'line' argument which is
5419 not called by default for backwards-compatibility reasons. Setting
5420 ``warnings.showwarning()`` to an implementation that lacks support
5421 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005484- Issue #2550: The approach used by client/server code for obtaining
5485 ports to listen on in network-oriented tests has been refined in an
5486 effort to facilitate running multiple instances of the entire
5487 regression test suite in parallel without issue.
5488 test_support.bind_port() has been fixed such that it will always
5489 return a unique port -- which wasn't always the case with the
5490 previous implementation, especially if socket options had been set
5491 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5492 new implementation of bind_port() will actually raise an exception
5493 if it is passed an AF_INET/SOCK_STREAM socket with either the
5494 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5495 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5496 the socket it's been passed. This currently only applies to
5497 Windows. This option prevents any other sockets from binding to the
5498 host/port we've bound to, thus removing the possibility of the
5499 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5500 when a second SOCK_STREAM socket binds and accepts to a host/port
5501 that's already been bound by another socket. The optional preferred
5502 port parameter to bind_port() has been removed. Under no
5503 circumstances should tests be hard coding ports!
5504
5505 test_support.find_unused_port() has also been introduced, which will
5506 pass a temporary socket object to bind_port() in order to obtain an
5507 unused port. The temporary socket object is then closed and
5508 deleted, and the port is returned. This method should only be used
5509 for obtaining an unused port in order to pass to an external program
5510 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5511 a parameter to a server-oriented class that doesn't give you direct
5512 access to the underlying socket used.
5513
5514 Finally, test_support.HOST has been introduced, which should be used
5515 for the host argument of any relevant socket calls (i.e. bind and
5516 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005517
5518 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005519 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005520 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5521 test_asynchat and test_socket_ssl.
5522
Georg Brandl3ee81df2008-05-17 18:14:43 +00005523 It is now possible for multiple instances of the regression test
5524 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00005803- Added the future_builtins module, which contains hex() and oct().
5804 These are the PEP 3127 version of these functions, designed to be
5805 compatible with the hex() and oct() builtins from Python 3.0. They
5806 differ slightly in their output formats from the existing, unchanged
5807 Python 2.6 builtins. The expected usage of the future_builtins
5808 module is:
5809 from future_builtins import hex, oct
5810
Eric Smith7ef40bf2008-02-20 23:34:22 +00005811- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5812 exponents for exponents with absolute value < 100. Follows C99
5813 standard. This is a change on Windows, which would use 3 digits.
5814 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5815 so that any alterations it does to the resulting string will be
5816 available in stringlib/formatter.h (for float.__format__).
5817
Eric Smith5a3c1352008-02-19 13:21:56 +00005818- Implemented PEP 3101, Advanced String Formatting. This adds a new
5819 builtin format(); a format() method for str and unicode; a
5820 __format__() method to object, str, unicode, int, long, float, and
5821 datetime; the class string.Formatter; and the C API
5822 PyObject_Format().
5823
Georg Brandl3ee81df2008-05-17 18:14:43 +00005824- Fixed several potential crashes, all caused by specially crafted
5825 __del__ methods exploiting objects in temporarily inconsistent
5826 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005827
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005828- Issue #2115: Important speedup in setting __slot__ attributes. Also

5836 in order to allow pymalloc to free more arenas. Python may give back
5837 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005838
Georg Brandl3ee81df2008-05-17 18:14:43 +00005839- Issue #2045: Fix an infinite recursion triggered when printing a
5840 subclass of collections.defaultdict, if its default_factory is set
5841 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005842
Christian Heimesf75dbef2008-02-08 00:11:31 +00005843- Fixed a minor memory leak in dictobject.c. The content of the free

5850 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005851 to compact the internal free lists of pre-allocted ints and floats.
5852
Georg Brandl3ee81df2008-05-17 18:14:43 +00005853- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5854 calls. Python expected the return type int but the fork familie
5855 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005869- Patch #1473257: generator objects gain a gi_code attribute. This is
5870 the same object as the func_code attribute of the function that
5871 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005872
Georg Brandl3ee81df2008-05-17 18:14:43 +00005873- Issue #1920: "while 0" statements were completely removed by the
5874 compiler, even in the presence of an "else" clause, which is
5875 supposed to be run when the condition is false. Now the compiler
5876 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005877

5885
Georg Brandl3ee81df2008-05-17 18:14:43 +00005886- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005887 several extension methods and modules do not work without unicode
5888 support.

5894
Georg Brandl6caad7d2008-01-26 14:19:22 +00005895- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005896 added.
5897
Christian Heimesc94e2b52008-01-14 04:13:37 +00005898- sys.float_info / PyFloat_GetInfo: The floating point information
5899 object was converted from a dict to a specialized structseq object.
5900
Georg Brandl3ee81df2008-05-17 18:14:43 +00005901- Patch #1816: Added sys.flags structseq. It exposes the status of
5902 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005903
Georg Brandl3ee81df2008-05-17 18:14:43 +00005904- Objects/structseq.c: Implemented new structseq representation. The

Georg Brandl3ee81df2008-05-17 18:14:43 +00005908- Patch #1700288: added a type attribute cache that caches method
5909 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005910
Neal Norwitz3fc15b82008-01-10 05:42:58 +00005911- Bug #1776: __import__() no longer accepts filenames on any platform.
5912 The first parameter to __import__() must be a valid module name.

Georg Brandlaed6c662008-01-07 17:25:53 +00005914- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
5915
Georg Brandl3ee81df2008-05-17 18:14:43 +00005916- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5917 envvar and sys.dont_write_bytecode attribute. All these can be set
5918 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005919
Georg Brandl3ee81df2008-05-17 18:14:43 +00005920- Improve some exception messages when Windows fails to load an
5921 extension module. Now we get for example '%1 is not a valid Win32
5922 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00005929- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005930 and INF. float("nan"), float("inf") and float("-inf") now work on
5931 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005933- Compiler now generates simpler and faster code for dictionary
5934 literals. The oparg for BUILD_MAP now indicates an estimated
5935 dictionary size. There is a new opcode, STORE_MAP, for adding
5936 entries to the dictionary.

5948
Nick Coghlanef01d822007-12-03 12:55:17 +00005949- PEP 366: Allow explicit relative imports when executing modules

Georg Brandl3ee81df2008-05-17 18:14:43 +00005965- Patch #1739468: Directories and zipfiles containing a __main__.py
5966 file can now be directly executed by passing their name to the
5967 interpreter. The directory/zipfile is automatically inserted as the
5968 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00005969
Georg Brandl3ee81df2008-05-17 18:14:43 +00005970- Issue #1265: Fix a problem with sys.settrace, if the tracing
5971 function uses a generator expression when at the same time the
5972 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005973
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005974- sets and frozensets now have an isdisjoint() method.
5975
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00005976- optimize the performance of builtin.sum().
5977

5979
Georg Brandl21e99f42010-03-07 15:23:59 +00005980- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005981 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5982 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005983
Georg Brandl3ee81df2008-05-17 18:14:43 +00005984- Issue #1686386: Tuple's tp_repr did not take into account the
5985 possibility of having a self-referential tuple, which is possible
5986 from C code. Nor did object's tp_str consider that a type's tp_str
5987 could do something that could lead to an inifinite recursion.
5988 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5989 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005990
Georg Brandl3ee81df2008-05-17 18:14:43 +00005991- Issue #1164: It was possible to trigger deadlock when using the
5992 'print' statement to write to a file since the GIL was not released
5993 as needed. Now PyObject_Print() does the right thing along with
5994 various tp_print implementations of the built-in types and those in
5995 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005996
Georg Brandl3ee81df2008-05-17 18:14:43 +00005997- Issue #1147: Exceptions were directly allowing string exceptions in
5998 their throw() method even though string exceptions no longer
5999 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00006000
Georg Brandl3ee81df2008-05-17 18:14:43 +00006001- Issue #1096: Prevent a segfault from getting the repr of a very
6002 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00006003
Brett Cannon1e534b52007-09-07 04:18:30 +00006004- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006005 PyObject_Call() never calling back out to Python code to trigger
6006 recursion depth updates/checks. Required the creation of a static
6007 RuntimeError instance in case normalizing an exception put the
6008 recursion check value past its limit. Fixes crashers
6009 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00006010
Georg Brandl3ee81df2008-05-17 18:14:43 +00006011- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00006024- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006025 __*__ attributes. (Some already existed, e.g., __doc__ and
6026 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006027
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00006028- Add -3 option to the interpreter to warn about features that are
6029 deprecated and will be changed/removed in Python 3.0.
6030
Georg Brandl2134e752007-05-21 20:34:16 +00006031- Patch #1686487: you can now pass any mapping after '**' in function
6032 calls.
6033
Collin Winter62903052007-05-18 23:11:24 +00006034- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006035 "except E as target:". This is to provide forwards compatibility
6036 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00006037
Brett Cannon229cee22007-05-05 01:34:02 +00006038- Deprecate BaseException.message as per PEP 352.
6039
Georg Brandl3ee81df2008-05-17 18:14:43 +00006040- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00006041 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00006042
Vinay Sajip8549ce32007-05-06 17:53:37 +00006043- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006044 setting a plain string, ie don't expand to single letter identifiers.
6045
Raymond Hettinger13936692007-04-11 18:40:58 +00006046- Request #1191699: Slices can now be pickled.
6047
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006048- Request #1193128: str.translate() now allows a None argument for
6049 translations that only remove characters without re-mapping the
6050 remaining characters.
6051
Georg Brandl5cb76c12007-03-21 09:00:39 +00006052- Patch #1682205: a TypeError while unpacking an iterable is no longer
6053 masked by a generic one with the message "unpack non-sequence".
6054
Neal Norwitzaa754b72007-03-21 06:39:48 +00006055- Remove unused file Python/fmod.c.
6056
Guido van Rossum143b5642007-03-23 04:58:42 +00006057- Bug #1683368: The object.__init__() and object.__new__() methods are
6058 now stricter in rejecting excess arguments. The only time when
6059 either allows excess arguments is when it is not overridden and the
6060 other one is. For backwards compatibility, when both are
6061 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006062 warning later). Also, type.__init__() insists on the same signature
6063 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00006064
Georg Brandl3ee81df2008-05-17 18:14:43 +00006065- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6066 object to complex using its __complex__() method before falling back
6067 to the __float__() method. Therefore, the functions in the cmath
6068 module now can operate on objects that define a __complex__()
6069 method.
Georg Brandl2b869942007-03-17 16:08:45 +00006070
Georg Brandl3ee81df2008-05-17 18:14:43 +00006071- Patch #1623563: allow __class__ assignment for classes with
6072 __slots__. The old and the new class are still required to have the
6073 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00006074
Georg Brandl3ee81df2008-05-17 18:14:43 +00006075- Patch #1642547: Fix an error/crash when encountering syntax errors

6079 ``object.__reduce_ex__()`` is called with an object that is faking
6080 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00006081
Georg Brandl3ee81df2008-05-17 18:14:43 +00006082- Patch #1680015: Don't modify __slots__ tuple if it contains an

6086
Georg Brandl7b9c5552007-03-12 14:30:05 +00006087- Bug #1678647: write a newline after printing an exception in any
6088 case, even when converting the value to a string failed.
6089
Georg Brandl871f1bc2007-03-12 13:17:36 +00006090- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006091 its argument, if it exists. If not, it will work like before. This
6092 allows customizing the output of dir() in the presence of a
6093 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00006094
Collin Winter276887b2007-03-12 16:11:39 +00006095- Patch #922167: Python no longer segfaults when faced with infinitely
6096 self-recursive reload() calls (as reported by bug #742342).
6097
Georg Brandl3ee81df2008-05-17 18:14:43 +00006098- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00006101- Patch #1491866: change the complex() constructor to allow
6102 parthensized forms. This means complex(repr(x)) now works instead of
6103 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006104
Georg Brandlaa2321b2007-03-07 00:40:28 +00006105- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006106 makes the filenames the warning module prints much more sensible
6107 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00006108

6110 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00006111 variable is given, but break into the interactive interpreter just
6112 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00006120- Patch #1674228: when assigning a slice (old-style), check for the
6121 sq_ass_slice instead of the sq_slice slot.
6122
Georg Brandl3ee81df2008-05-17 18:14:43 +00006123- When printing an unraisable error, don't print exceptions. before
6124 the name. This duplicates the behavior whening normally printing
6125 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006658 AttributeError instead of an IOError when the server's response
6659 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00006660

Georg Brandl3ee81df2008-05-17 18:14:43 +00006665- Patch #1429539: pdb now correctly initializes the __main__ module
6666 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00006667 correctly now.
6668

6675
Georg Brandl3ee81df2008-05-17 18:14:43 +00006676- Patch #1530482: add pydoc.render_doc() which returns the

6691
Georg Brandl92a6bae2007-03-13 17:43:32 +00006692- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00006693 are set for invalid interpolation sequences that would lead to
6694 errors on reading back those values.

6734 Python would crash instead of raising an error.
6735

6737 returned string up to the first NUL character.
6738

6748
Georg Brandl3ee81df2008-05-17 18:14:43 +00006749- unittest now verifies more of its assumptions. In particular,
6750 TestCase and TestSuite subclasses (not instances) are no longer
6751 accepted in TestSuite.addTest(). This should cause no
6752 incompatibility since it never made sense with ordinary subclasses
6753 -- the failure just occurred later, with a more cumbersome
6754 exception.

6764
Georg Brandl3ee81df2008-05-17 18:14:43 +00006765- Patch #1673619: setup.py identifies extension modules it doesn't

7125 complex, tuple, list, dict, set, and frozenset. Formerly, it would

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00007142- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00007143 time so that opening a database previously created with the DB_DUP
7144 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7145 opens. Specifically: dictionary assignment to a DB object will
7146 replace all values for a given key when the database allows
7147 duplicate values. DB users should use DB.put(k, v) when they want
7148 to store duplicates; not DB[k] = v.

7155 characters with ASCII value less than 32. Also, it correctly quotes
7156 dots only if they occur on a single line, as opposed to the previous
7157 behavior of quoting dots if they are the second character of any
7158 line.

7504 of w# format code incorrectly truncated the length to an int, even
7505 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
7506 incorrect results with huge strings.
