426
Raymond Hettinger20397532010-09-12 02:11:45 +0000427- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
428 This prevents user-created self-referencing ordered dictionaries from
429 becoming permanently uncollectable GC garbage. The downside is that
430 removing __del__ means that the internal doubly-linked list has to wait for
431 GC collection rather than freeing memory immediately when the refcnt drops
432 to zero.
433
Raymond Hettingerffd2a422010-09-10 10:47:22 +0000434- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently

437
Antoine Pitrouc818ed42010-09-07 21:40:25 +0000438- Issue #9792: In case of connection failure, socket.create_connection()
439 would swallow the exception and raise a new one, making it impossible
440 to fetch the original errno, or to filter timeout errors. Now the
441 original error is re-raised.
442
Antoine Pitrouf4f61712010-09-07 16:34:47 +0000443- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
444 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
445 be updated back after the system call. Original patch by Brian Brazil.
446

451 ConfigParser.write.
452
Daniel Stutzbach66c981b2010-08-31 20:29:39 +0000453- Issue #808164: Fixed socket.close to avoid references to globals, to
454 avoid issues when socket.close is called from a __del__ method.
455

461 falling into recursion.
462
R. David Murray7c4bf552010-08-25 01:45:57 +0000463- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
464 character years even if the message contains RFC822 two character years.
465
Daniel Stutzbach91287322010-08-24 21:09:30 +0000466- Issue #8750: Fixed MutableSet's methods to correctly handle
467 reflexive operations, namely x -= x and x ^= x.
468

478 module now correctly return a set. (Patch by Eli Bendersky.)
479
Antoine Pitrou3ebaed62010-08-21 19:17:25 +0000480- Issue #9617: Signals received during a low-level write operation aren't
481 ignored by the buffered IO layer anymore.
482
Benjamin Peterson52c36052010-08-21 03:03:22 +0000483- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
484 are not held onto after they are deleted elsewhere.
485
Raymond Hettingera54b2da2010-08-17 19:03:06 +0000486- Issue #9626: the view methods for collections.OrderedDict() were returning
487 the unordered versions inherited from dict. Those methods are now
488 overridden to provide ordered views.
489

493
Antoine Pitroue1436d12010-08-12 15:25:51 +0000494- Issue #7467: when reading a file from a ZIP archive, its CRC is checked

496 case in Python 2.5 and earlier).
497
Antoine Pitroucb4f47c2010-08-11 13:40:17 +0000498- Issue #9550: a BufferedReader could issue an additional read when the
499 original read request had been satisfied, which could block indefinitely
500 when the underlying raw IO channel was e.g. a socket. Report and original
501 patch by Jason V. Miller.
502
Fred Drake0a1fa0e2010-08-10 13:09:54 +0000503- Issue #9551: Don't raise TypeError when setting the value to None for

505
Antoine Pitrou8cdede42010-08-10 00:04:13 +0000506- Issue #6915: Under Windows, os.listdir() didn't release the Global

1277
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00001278- Issue #8329: Don't return the same lists from select.select when no fds are
1279 changed.

Georg Brandlfee0f442010-05-22 21:26:21 +00001281- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'

Georg Brandlfee0f442010-05-22 21:26:21 +00001291- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1292 with a non-empty format string. This is an effort to future-proof user
1293 code. If a derived class does not currently implement __format__ but later
1294 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00001295 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00001296 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00001346- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1347 InvalidOperation instead of returning False. (Comparisons involving a quiet
1348 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1349 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00001350
Georg Brandlfee0f442010-05-22 21:26:21 +00001351- Issue #2531: Comparison operations between floats and Decimal instances now
1352 return a result based on the numeric values of the operands; previously they
1353 returned an arbitrary result based on the relative ordering of id(float) and
1354 id(Decimal).

Georg Brandlfee0f442010-05-22 21:26:21 +00001368- Comparisons using one of <, <=, >, >= between a complex instance and a
1369 Fractions instance now raise TypeError instead of returning True/False. This
1370 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1371 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00001728- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
1729 and add the additional members returned in an OSVERSIONINFOEX structure. The
1730 new members are service_pack_major, service_pack_minor, suite_mask, and

Georg Brandlba83f822010-03-14 09:50:54 +00001733- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
1734 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
1735 returning NULL. The macro now returns a statically allocated empty string
1736 instead.

1746 strings,
1747 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
1748 numeric strings corresponding to subnormal values,
1749 (3) a memory leak for some values large enough to cause overflow, and
1750 (4) a number of flaws that could lead to incorrectly rounded results.

Antoine Pitroud840e512010-02-04 20:20:18 +00001781- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00001782 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00001783 Also, raise ValueError rather than TypeError when an unknown TIPC address
1784 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001788- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00001789 file position when calling `truncate()`. It would previously change the file
1790 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001791 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
1792
Georg Brandlba83f822010-03-14 09:50:54 +00001793- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
1794 class used to represent files stored inside an archive. The new
1795 implementation is significantly faster and can be wrapped in a
1796 ``io.BufferedReader`` object for more speedups. It also solves an issue
1797 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
1798 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +00001808- Issue #7748: Since unicode values are supported for some metadata options in
1809 Distutils, the DistributionMetadata get_* methods will now return an utf-8
1810 encoded string for them. This ensures that the upload and register commands
1811 send the correct values to PyPI without any error.

1886-----------------
1887
Georg Brandlba83f822010-03-14 09:50:54 +00001888- The ``__complex__()`` method is now looked up on the class of instances to
1889 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00001890
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00001891- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
1892 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
1893
Mark Dickinson1b34d252010-01-01 17:27:30 +00001894- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001895 DeprecationWarning when passed a float argument where an integer was expected.
1896 These functions and methods now raise TypeError instead. The majority of the
1897 effects of this change are in the extension modules, but some core functions
1898 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1899 and many unicode/str methods.

1910 used to drop the time part of the result.
1911
Georg Brandlba83f822010-03-14 09:50:54 +00001912- Issue #1811: Improve accuracy and cross-platform consistency for true division
1913 of integers: the result of a/b is now correctly rounded for ints a and b (at
1914 least on IEEE 754 platforms), and in particular does not depend on the
1915 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +00001916
Georg Brandlba83f822010-03-14 09:50:54 +00001917- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
1918 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
1919 in the subclass.

Ronald Oussoren92919a62009-12-24 13:30:58 +00001922 executables on OSX.
1923
Georg Brandlba83f822010-03-14 09:50:54 +00001924 These executables now work properly with the arch(1) command: ``arch -ppc
1925 python`` will start a universal binary version of python in PPC mode (unlike
1926 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +00001949 renaming of `cPickle` to `pickle`. The warning was annoying since there's no

Georg Brandlba83f822010-03-14 09:50:54 +00002082- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2083 decimal string that's guaranteed to round back to x under correct rounding
2084 (with round-half-to-even rounding mode). Previously it gave a string based on
2085 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2086 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2087 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002088
Georg Brandlba83f822010-03-14 09:50:54 +00002089- Issue #7117: On almost all platforms: float-to-string and string-to-float
2090 conversions within Python are now correctly rounded. Places these conversions
2091 occur include: str for floats and complex numbers; the float and complex
2092 constructors; old-style and new-style numeric formatting; serialization and
2093 deserialization of floats and complex numbers using marshal, pickle and json;
2094 parsing of float and imaginary literals in Python code; Decimal-to-float
2095 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002096
Georg Brandlba83f822010-03-14 09:50:54 +00002097 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2098 providing correctly-rounded strtod and dtoa C functions. This code is
2099 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2100 the C compiler. There may be a small number of platforms on which correct
2101 operation of this code cannot be guaranteed, so the code is not used: notably,
2102 this applies to platforms where the C double format is not IEEE 754 binary64,
2103 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2104 and Python's configure script is unable to determine how to change the FPU
2105 precision. On these platforms conversions use the platform strtod and dtoa,
2106 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00002108- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2109 uses the correctly-rounded string <-> float conversions described above (when
2110 available), and so produces correctly rounded results that will display nicely
2111 under the float repr. There are two related small changes: (1) round now
2112 accepts any class with an ``__index__()`` method for its second argument (but
2113 no longer accepts floats for the second argument), and (2) an excessively
2114 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2115 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00002333 untrackable objects are not tracked by the garbage collector. This can reduce
2334 the size of collections and therefore the garbage collection overhead on
2335 long-running programs, depending on their particular use of datatypes.

Georg Brandlba83f822010-03-14 09:50:54 +00002341- Issue #4258: Make it possible to use base 2**30 instead of base 2**15 for the
2342 internal representation of integers, for performance reasons. Base 2**30 is
2343 enabled by default on 64-bit machines. Add --enable-big-digits option to
2344 configure, which overrides the default. Add sys.long_info structseq to
2345 provide information about the internal format.

2376
Georg Brandl29c6a282009-04-05 20:23:13 +00002377- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +00002378 were suppressing all exceptions. These include list(), filter(), map(),

2380
Benjamin Peterson596d3062009-01-19 15:42:23 +00002381- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os

2407
Georg Brandlba83f822010-03-14 09:50:54 +00002408- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
2409 existing .py counterpart, override the co_filename attributes of all code
2410 objects if the original filename is obsolete (which can happen if the file has
2411 been renamed, moved, or if it is accessed through different paths). Patch by

2452 ``offsetof(PyStringObject, ob_sval) + 1`` when allocating memory for str
2453 instances. On a typical machine this saves 3 bytes of memory (on average) per

2465
Georg Brandlba83f822010-03-14 09:50:54 +00002466- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
2467 file objects with closefd=False. The file descriptor is still kept open but
2468 the file object behaves like a closed file. The ``FileIO`` object also got a
2469 new readonly attribute ``closefd``.

2488
Benjamin Peterson399b1fe2008-10-25 02:53:28 +00002489- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +00002490 because it is a reserved word in 3.x.

Georg Brandlba83f822010-03-14 09:50:54 +00002492- On windows, ``os.chdir()`` given unicode was not working if
2493 GetCurrentDirectoryW returned a path longer than MAX_PATH. (But It's doubtful
2494 this code path is really executed because I cannot move to such directory on
2495 win2k)
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +00002496
Georg Brandlba83f822010-03-14 09:50:54 +00002497- Issue #4069: When ``set.remove(element)`` is used with a set element, the
2498 element is temporarily replaced with an equivalent frozenset. But the
2499 eventual KeyError would always report the empty ``frozenset()`` as the missing
2500 key. Now it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +00002520- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
2521 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2522 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2523 of using the replace error handler in PyUnicode_DecodeUTF8().
2524
Walter Dörwald726ba8e2009-05-06 14:32:35 +00002525- Issue #3739: The unicode-internal encoder now reports the number of characters

Georg Brandlba83f822010-03-14 09:50:54 +00002528- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc

2530 gives improved memory leak detection when running under Valgrind, while taking
2531 advantage of pymalloc at other times.

3697 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
3698 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
3699 neither __int__ nor __long__, TypeError used to be raised (with a
3700 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
3701 struct.error in other cases.

3704 argument with an __int__ method can be packed, but use of this feature
3705 triggers a DeprecationWarning.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003898- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

3900 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3901 ``printf`` function, whereas PyString_FromFormat has an independent

Brett Cannon1eaf0742008-09-02 01:25:16 +00003999 warnings.catch_warnings() along with some API cleanup. Expanding the tests
4000 for catch_warnings() also led to an improvement in the raising of a
4001 DeprecationWarning related to warnings.warn_explicit().
4002

4025
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00004026- Issue #2975: When compiling several extension modules with Visual Studio 2008
4027 from the same python interpreter, some environment variables would grow
4028 without limit.
4029
Benjamin Peterson37346b22008-08-23 20:27:43 +00004030- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
4031 exploitation of poor argument checking.
4032
Gerhard Häringef2276b2008-09-12 13:54:06 +00004033- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004067What's New in Python 2.6 beta 3?
4068================================
4069
Barry Warsaw07a4a382008-08-21 01:15:08 +00004070*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004071
4072Core and Builtins
4073-----------------
4074
Guido van Rossumf8402962008-08-20 15:01:50 +00004075- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4076 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4077 extensions do not automatically benefit from the class attribute
4078 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4079 to their tp_flags field if they care. This is a backwards
4080 compatibility feature; in 3.0, all types will use the cache by
4081 default.
4082
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004083- Keyword arguments can now follow starred arguments. (``f(a, *args,
4084 keyword=23)`` is now valid syntax.)
4085
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004086- ctypes function pointers that are COM methods have a boolean True
4087 value again.
4088
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004089- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4090 by denying s# to parse objects that have a releasebuffer procedure,
4091 and introducing s*.
4092
Georg Brandl1e13ea92008-08-11 09:07:59 +00004093- Issue #3537: Fix an assertion failure when an empty but presized dict
4094 object was stored in the freelist.
4095
Mark Dickinsonb6467572008-08-04 21:30:09 +00004096- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4097 ValueError consistently across platforms.
4098
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004099- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4100 (64bit Unix, for example), unichr() would truncate its argument and return
4101 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4102
Neal Norwitze7d8be82008-07-31 17:17:14 +00004103- Apply security patches from Apple.
4104
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004105- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4106 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4107
Antoine Pitrou92f82162008-07-25 22:22:08 +00004108- Issue #1819: function calls with several named parameters are now on
4109 average 35% faster (as measured by pybench).
4110
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004111- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4112 the python debugger steps into a class statement: the free variables (local
4113 variables defined in an outer scope) would be deleted from the outer scope.
4114
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004115- Issue #2620: Overflow checking when allocating or reallocating memory
4116 was not always being done properly in some python types and extension
4117 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4118 all been updated to perform better checks and places in the code that
4119 would previously leak memory on the error path when such an allocation
4120 failed have been fixed.
4121
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004122Library
4123-------
4124
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00004125- Issue #3612: Added some missing basic types in ctypes.wintypes.
4126
Benjamin Petersone977ad42008-08-20 01:42:01 +00004127- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4128 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4129
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004130- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4131 version reported by these tools does not necessarily follow the python
4132 version numbering scheme, so the module is less strict when parsing it.
4133
Nick Coghlanf70385a2008-08-18 12:42:46 +00004134- Issue #2235: Added Py3k warnings for types which will become unhashable
4135 under the stricter __hash__ inheritance rules in 3.0. Several types
4136 which did not meet the rules for hash invariants and were already
4137 unhashable in 3.0 have now been explicitly flagged as unhashable in
4138 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4139 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4140
Brett Cannon88f801d2008-08-18 00:46:22 +00004141- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

4149
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004150- Issue #3575: Incremental decoder's decode function now takes bytearray
4151 by using 's*' instead of 't#'.
4152
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004153- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004154 fails unicode conversion on 2nd parameter. (windows only)
4155
Georg Brandl222e2082010-08-01 22:27:39 +00004156- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004157 in a redirect.
4158

Brett Cannon721b1452008-08-16 22:00:27 +00004160 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004161
Facundo Batistaeb90b782008-08-16 14:44:07 +00004162- Issue #2776: fixed small issue when handling an URL with double slash
4163 after a 302 response in the case of not going through a proxy.
4164
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004165- Issue #2676: in the email package, content-type parsing was hanging on
4166 pathological input because of quadratic or exponential behaviour of a
4167 regular expression.
4168
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004169- Issue #3476: binary buffered reading through the new "io" library is now
4170 thread-safe.
4171
Brett Cannonbf3157b2008-08-14 05:00:03 +00004172- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4173 since mimetools itself is deprecated. Because modules are cached, all
4174 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4175
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004176- Issue #3134: shutil referenced undefined WindowsError symbol.
4177
Robert Schuppenies14646332008-08-10 11:01:53 +00004178- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4179 menu entries were not deleted.
4180
Brett Cannon83e81842008-08-09 23:30:55 +00004181- Copied the implementation of reduce() to _functools.reduce() to have a
4182 version that did not raise a DeprecationWarning under -3.
4183
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004184- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4185 a MemoryError rather than silently stop the iteration.
4186
Guido van Rossum59ce9012008-08-09 14:55:34 +00004187- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4188 to _sre.compile() will now be rejected. This should not affect anybody
4189 since the re.compile() function never generates invalid re-bytecode.
4190
Skip Montanaroa032bf42008-08-08 22:52:51 +00004191- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4192 upon first access it can be automatically initialized from the csv file if
4193 it wasn't initialized during instantiation.
4194
Brett Cannon3aa2a492008-08-06 22:28:09 +00004195- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4196 the reload() built-in has been removed.
4197
Brett Cannon7e30b672008-08-04 21:52:25 +00004198- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00004199 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00004210 asking for a specific length. This problem only affected files opened
4211 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00004212

4257 regarding lack of coverage of new-style classes have also been
4258 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00004261What's New in Python 2.6 beta 2?
4262================================
4263
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004264*Release date: 17-Jul-2008*
4265
Raymond Hettingere3ae6552008-06-20 04:18:15 +00004266Core and Builtins
4267-----------------
4268
Georg Brandl3e483f62008-07-16 22:57:41 +00004269- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4270 its methods now allow for items objects that can be converted to
4271 an integer using operator.index().
4272
Mark Dickinson64b7e502008-07-16 09:40:03 +00004273- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4274 produced a ValueError instead of giving the correct float.
4275
Eric Smitha5fa5a22008-07-16 00:11:49 +00004276- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4277 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4278
Mark Dickinson7103aa42008-07-15 19:08:33 +00004279- Issue #3008: the float type has a new instance method 'float.hex'
4280 and a new class method 'float.fromhex' to convert floating-point
4281 numbers to and from hexadecimal strings, respectively.
4282
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004283- Issue #2235: __hash__ is once again inherited by default. To allow
4284 collections.Hashable to remain meaningful in the presence of the
4285 default hash implementation (object.__hash__), it is now possible
4286 to explicit block inheritance of hash by setting __hash__=None at
4287 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4288 level.
4289
Nick Coghlanb028f502008-07-13 14:52:36 +00004290- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4291 the parent module cannot be found while performing an absolute import.
4292 This means that an incorrectly defined __package__ attribute will
4293 now only prevent relative imports in that module rather than causing
4294 all imports from that module to fail.
4295
Nick Coghlan14ff9942008-07-08 14:21:42 +00004296- Issue #2517: Allow unicode messages in Exceptions again by correctly
4297 bypassing the instance dictionary when looking up __unicode__ on
4298 new-style classes.
4299
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00004300- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
4301 set to a custom object whose write() method happens to install
4302 another file in sys.stdout.
4303
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00004304- Issue #3088: Corrected a race condition in classes derived from
4305 threading.local: the first member set by a thread could be saved in
4306 another thread's dictionary.
4307
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004308- Issue #3004: Minor change to slice.indices(): the start and stop
4309 arguments are now treated identically, making the behaviour easier
4310 to describe and understand. For example, slice(None, -10,
4311 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4312 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4313 10, -1).
4314
Georg Brandl278fc502008-07-19 12:46:12 +00004315- Issue #3219: Calling a function with repeated keyword arguments,
4316 f(a=2, a=23), would not cause a syntax error. This was a regression
4317 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00004318
Georg Brandl278fc502008-07-19 12:46:12 +00004319- Issue #2862: Make int and float freelist management consistent with
4320 other freelists. Changes their CompactFreeList apis into
4321 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00004322
Brett Cannon8bb8fa52008-07-02 01:57:08 +00004323Library
4324-------
4325
Thomas Heller57adf222008-08-14 19:10:48 +00004326- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
4327 api functions without holding the GIL, which could lead to a fatal
4328 error when they failed.
4329
Martin v. Löwisaabf4042008-08-02 07:20:25 +00004330- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.
4331

4337
Jesse Noller13e9d582008-07-16 14:32:36 +00004338- Issue #3125: Remove copy_reg in multiprocessing and replace it with
4339 ForkingPickler.register() to resolve conflict with ctypes.
4340
Vinay Sajip51e65192008-07-18 09:01:10 +00004341- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00004342
Thomas Heller880f5292008-07-15 19:39:38 +00004343- Issue #3313: Fixed a crash when a failed dlopen() call does not set
4344 a valid dlerror() message.
4345
Thomas Heller2bad6572008-07-15 17:19:50 +00004346- Issue #3258: Fixed a crash when a ctypes POINTER type to an
4347 incomplete structure was created.
4348
Brett Cannon3d0b9f02008-07-13 01:15:07 +00004349- Issue #3339: dummy_thread.acquire() should not return None.
4350
Raymond Hettingerb01713e2008-07-10 14:34:57 +00004351- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
4352
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004353- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00004354
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004355- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
4356 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004357 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004358 content-length. The problem had been corrected in the 2.4 branch, but never
4359 merged into trunk.
4360
Georg Brandle78fbcc2008-07-05 10:13:36 +00004361- Issue #2663: add filtering capability to shutil.copytree().
4362

4364
4365- Issue #1526: Allow more than 64k files to be added to Zip64 file.
4366
4367- Issue #1746: Correct handling of zipfile archive comments (previously
4368 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00004369 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00004370
Vinay Sajip51e65192008-07-18 09:01:10 +00004371- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004372 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00004373
Nick Coghlanc060b0e2008-07-02 13:09:19 +00004374- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
4375 handling is now the same as that of other special attributes like __name__).
4376
Brett Cannon8bb8fa52008-07-02 01:57:08 +00004377- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
4378 removal in Python 3.0 in favor of urllib2.urlopen().

Georg Brandl3ee81df2008-05-17 18:14:43 +00004829- Issue #1631171: Re-implement the 'warnings' module in C (the
4830 original Python code has been kept as backup). This will allow for
4831 using the 'warning's machinery in such places as the parser where
4832 use of pure Python code is not possible. Both the ``showarning()``
4833 and ``formatwarning()`` gain an optional 'line' argument which is
4834 not called by default for backwards-compatibility reasons. Setting
4835 ``warnings.showwarning()`` to an implementation that lacks support
4836 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004899- Issue #2550: The approach used by client/server code for obtaining
4900 ports to listen on in network-oriented tests has been refined in an
4901 effort to facilitate running multiple instances of the entire
4902 regression test suite in parallel without issue.
4903 test_support.bind_port() has been fixed such that it will always
4904 return a unique port -- which wasn't always the case with the
4905 previous implementation, especially if socket options had been set
4906 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4907 new implementation of bind_port() will actually raise an exception
4908 if it is passed an AF_INET/SOCK_STREAM socket with either the
4909 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4910 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4911 the socket it's been passed. This currently only applies to
4912 Windows. This option prevents any other sockets from binding to the
4913 host/port we've bound to, thus removing the possibility of the
4914 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4915 when a second SOCK_STREAM socket binds and accepts to a host/port
4916 that's already been bound by another socket. The optional preferred
4917 port parameter to bind_port() has been removed. Under no
4918 circumstances should tests be hard coding ports!
4919
4920 test_support.find_unused_port() has also been introduced, which will
4921 pass a temporary socket object to bind_port() in order to obtain an
4922 unused port. The temporary socket object is then closed and
4923 deleted, and the port is returned. This method should only be used
4924 for obtaining an unused port in order to pass to an external program
4925 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4926 a parameter to a server-oriented class that doesn't give you direct
4927 access to the underlying socket used.
4928
4929 Finally, test_support.HOST has been introduced, which should be used
4930 for the host argument of any relevant socket calls (i.e. bind and
4931 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004932
4933 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004934 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004935 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4936 test_asynchat and test_socket_ssl.
4937
Georg Brandl3ee81df2008-05-17 18:14:43 +00004938 It is now possible for multiple instances of the regression test
4939 suite to run in parallel without issue.

5095 processor information on Windows XP and later. As a result,
Marc-André Lemburga1867752008-03-20 18:08:00 +00005096 platform.machine() and platform.processor() will report this
5097 information as well.

Eric Smitha73fbe72008-02-23 03:09:44 +00005218- Added the future_builtins module, which contains hex() and oct().
5219 These are the PEP 3127 version of these functions, designed to be
5220 compatible with the hex() and oct() builtins from Python 3.0. They
5221 differ slightly in their output formats from the existing, unchanged
5222 Python 2.6 builtins. The expected usage of the future_builtins
5223 module is:
5224 from future_builtins import hex, oct
5225
Eric Smith7ef40bf2008-02-20 23:34:22 +00005226- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5227 exponents for exponents with absolute value < 100. Follows C99
5228 standard. This is a change on Windows, which would use 3 digits.
5229 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5230 so that any alterations it does to the resulting string will be
5231 available in stringlib/formatter.h (for float.__format__).
5232
Eric Smith5a3c1352008-02-19 13:21:56 +00005233- Implemented PEP 3101, Advanced String Formatting. This adds a new
5234 builtin format(); a format() method for str and unicode; a
5235 __format__() method to object, str, unicode, int, long, float, and
5236 datetime; the class string.Formatter; and the C API
5237 PyObject_Format().
5238
Georg Brandl3ee81df2008-05-17 18:14:43 +00005239- Fixed several potential crashes, all caused by specially crafted
5240 __del__ methods exploiting objects in temporarily inconsistent
5241 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005242
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005243- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00005244 prevent a possible crash: an Abstract Base Class would try to access
5245 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00005246

Georg Brandl3ee81df2008-05-17 18:14:43 +00005250- Clear all free lists during a gc.collect() of the highest generation
5251 in order to allow pymalloc to free more arenas. Python may give back
5252 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005253
Georg Brandl3ee81df2008-05-17 18:14:43 +00005254- Issue #2045: Fix an infinite recursion triggered when printing a
5255 subclass of collections.defaultdict, if its default_factory is set
5256 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005257
Christian Heimesf75dbef2008-02-08 00:11:31 +00005258- Fixed a minor memory leak in dictobject.c. The content of the free
5259 list was not freed on interpreter shutdown.
5260
Georg Brandl21e99f42010-03-07 15:23:59 +00005261- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00005262 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00005263
Georg Brandl3ee81df2008-05-17 18:14:43 +00005264- Patch #1953: Added ``sys._compact_freelists()`` and the C API
5265 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005266 to compact the internal free lists of pre-allocted ints and floats.
5267
Georg Brandl3ee81df2008-05-17 18:14:43 +00005268- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5269 calls. Python expected the return type int but the fork familie
5270 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00005271
Georg Brandl3ee81df2008-05-17 18:14:43 +00005272- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00005284- Patch #1473257: generator objects gain a gi_code attribute. This is
5285 the same object as the func_code attribute of the function that
5286 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005287
Georg Brandl3ee81df2008-05-17 18:14:43 +00005288- Issue #1920: "while 0" statements were completely removed by the
5289 compiler, even in the presence of an "else" clause, which is
5290 supposed to be run when the condition is false. Now the compiler
5291 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005292
Guido van Rossumeead05f2008-01-24 18:21:02 +00005293- A few crashers fixed: weakref_in_del.py (issue #1377858);
5294 loosing_dict_ref.py (issue #1303614, test67.py);
5295 borrowed_ref_[34].py (not in tracker).
5296

5300
Georg Brandl3ee81df2008-05-17 18:14:43 +00005301- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005302 several extension methods and modules do not work without unicode
5303 support.
5304
Georg Brandl26543b12008-01-21 18:36:51 +00005305- Issue #1882: when compiling code from a string, encoding cookies in the
5306 second line of code were not always recognized correctly.
5307
Georg Brandl14404b62008-01-19 19:27:05 +00005308- Issue #1679: "0x" was taken as a valid integer literal.
5309
Georg Brandl6caad7d2008-01-26 14:19:22 +00005310- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005311 added.
5312
Christian Heimesc94e2b52008-01-14 04:13:37 +00005313- sys.float_info / PyFloat_GetInfo: The floating point information
5314 object was converted from a dict to a specialized structseq object.
5315
Georg Brandl3ee81df2008-05-17 18:14:43 +00005316- Patch #1816: Added sys.flags structseq. It exposes the status of
5317 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005318
Georg Brandl3ee81df2008-05-17 18:14:43 +00005319- Objects/structseq.c: Implemented new structseq representation. The
5320 patch makes structseqs (e.g. the return value of os.stat) more
5321 readable.

5330
Georg Brandl3ee81df2008-05-17 18:14:43 +00005331- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5332 envvar and sys.dont_write_bytecode attribute. All these can be set
5333 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005334
Georg Brandl3ee81df2008-05-17 18:14:43 +00005335- Improve some exception messages when Windows fails to load an
5336 extension module. Now we get for example '%1 is not a valid Win32
5337 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00005344- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005345 and INF. float("nan"), float("inf") and float("-inf") now work on
5346 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005348- Compiler now generates simpler and faster code for dictionary
5349 literals. The oparg for BUILD_MAP now indicates an estimated
5350 dictionary size. There is a new opcode, STORE_MAP, for adding
5351 entries to the dictionary.

5381 file can now be directly executed by passing their name to the
5382 interpreter. The directory/zipfile is automatically inserted as the
5383 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005385- Issue #1265: Fix a problem with sys.settrace, if the tracing
5386 function uses a generator expression when at the same time the
5387 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005388

5394
Georg Brandl21e99f42010-03-07 15:23:59 +00005395- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005396 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5397 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005398
Georg Brandl3ee81df2008-05-17 18:14:43 +00005399- Issue #1686386: Tuple's tp_repr did not take into account the
5400 possibility of having a self-referential tuple, which is possible
5401 from C code. Nor did object's tp_str consider that a type's tp_str
5402 could do something that could lead to an inifinite recursion.
5403 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5404 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005405
Georg Brandl3ee81df2008-05-17 18:14:43 +00005406- Issue #1164: It was possible to trigger deadlock when using the
5407 'print' statement to write to a file since the GIL was not released
5408 as needed. Now PyObject_Print() does the right thing along with
5409 various tp_print implementations of the built-in types and those in
5410 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005411
Georg Brandl3ee81df2008-05-17 18:14:43 +00005412- Issue #1147: Exceptions were directly allowing string exceptions in

Brett Cannona0c05512007-09-10 21:38:27 +00005418
Brett Cannon1e534b52007-09-07 04:18:30 +00005419- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005420 PyObject_Call() never calling back out to Python code to trigger
5421 recursion depth updates/checks. Required the creation of a static
5422 RuntimeError instance in case normalizing an exception put the
5423 recursion check value past its limit. Fixes crashers
5424 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005425

Neal Norwitz0ac60192007-05-27 04:08:54 +00005439- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005440 __*__ attributes. (Some already existed, e.g., __doc__ and
5441 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005442
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005443- Add -3 option to the interpreter to warn about features that are
5444 deprecated and will be changed/removed in Python 3.0.
5445
Georg Brandl2134e752007-05-21 20:34:16 +00005446- Patch #1686487: you can now pass any mapping after '**' in function
5447 calls.
5448
Collin Winter62903052007-05-18 23:11:24 +00005449- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005450 "except E as target:". This is to provide forwards compatibility
5451 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00005458- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005459 setting a plain string, ie don't expand to single letter identifiers.
5460
Raymond Hettinger13936692007-04-11 18:40:58 +00005461- Request #1191699: Slices can now be pickled.
5462
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005463- Request #1193128: str.translate() now allows a None argument for
5464 translations that only remove characters without re-mapping the
5465 remaining characters.
5466
Georg Brandl5cb76c12007-03-21 09:00:39 +00005467- Patch #1682205: a TypeError while unpacking an iterable is no longer

5471
Guido van Rossum143b5642007-03-23 04:58:42 +00005472- Bug #1683368: The object.__init__() and object.__new__() methods are
5473 now stricter in rejecting excess arguments. The only time when
5474 either allows excess arguments is when it is not overridden and the
5475 other one is. For backwards compatibility, when both are
5476 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005477 warning later). Also, type.__init__() insists on the same signature
5478 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005479
Georg Brandl3ee81df2008-05-17 18:14:43 +00005480- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5481 object to complex using its __complex__() method before falling back
5482 to the __float__() method. Therefore, the functions in the cmath
5483 module now can operate on objects that define a __complex__()
5484 method.

5488 same slot names.

5495 its type.

5501
Georg Brandl7b9c5552007-03-12 14:30:05 +00005502- Bug #1678647: write a newline after printing an exception in any
5503 case, even when converting the value to a string failed.
5504
Georg Brandl871f1bc2007-03-12 13:17:36 +00005505- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005506 its argument, if it exists. If not, it will work like before. This
5507 allows customizing the output of dir() in the presence of a
5508 __getattr__().

5517 parthensized forms. This means complex(repr(x)) now works instead of
5518 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005519
Georg Brandlaa2321b2007-03-07 00:40:28 +00005520- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005521 makes the filenames the warning module prints much more sensible
5522 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00005535- Patch #1674228: when assigning a slice (old-style), check for the
5536 sq_ass_slice instead of the sq_slice slot.
5537
Georg Brandl3ee81df2008-05-17 18:14:43 +00005538- When printing an unraisable error, don't print exceptions. before
5539 the name. This duplicates the behavior whening normally printing
5540 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006073 AttributeError instead of an IOError when the server's response

Georg Brandlf66b6032007-03-14 08:27:52 +00006075

Georg Brandl3ee81df2008-05-17 18:14:43 +00006091- Patch #1530482: add pydoc.render_doc() which returns the

6106
Georg Brandl92a6bae2007-03-13 17:43:32 +00006107- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00006108 are set for invalid interpolation sequences that would lead to
6109 errors on reading back those values.

6165 TestCase and TestSuite subclasses (not instances) are no longer
6166 accepted in TestSuite.addTest(). This should cause no
6167 incompatibility since it never made sense with ordinary subclasses
6168 -- the failure just occurred later, with a more cumbersome
6169 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006558 time so that opening a database previously created with the DB_DUP
6559 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6560 opens. Specifically: dictionary assignment to a DB object will
6561 replace all values for a given key when the database allows
6562 duplicate values. DB users should use DB.put(k, v) when they want
6563 to store duplicates; not DB[k] = v.

6572 behavior of quoting dots if they are the second character of any
6573 line.

6919 of w# format code incorrectly truncated the length to an int, even
6920 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
6921 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006951- Added case insensitive comparison methods ``PyOS_stricmp(char*,
6952 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
