Raymond Hettinger20397532010-09-12 02:11:45 +0000713- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
714 This prevents user-created self-referencing ordered dictionaries from
715 becoming permanently uncollectable GC garbage. The downside is that
716 removing __del__ means that the internal doubly-linked list has to wait for
717 GC collection rather than freeing memory immediately when the refcnt drops
718 to zero.

726 to fetch the original errno, or to filter timeout errors. Now the
727 original error is re-raised.
728
Antoine Pitrouf4f61712010-09-07 16:34:47 +0000729- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,

Daniel Stutzbach66c981b2010-08-31 20:29:39 +0000739- Issue #808164: Fixed socket.close to avoid references to globals, to

R. David Murray7c4bf552010-08-25 01:45:57 +0000749- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
750 character years even if the message contains RFC822 two character years.
751
Daniel Stutzbach91287322010-08-24 21:09:30 +0000752- Issue #8750: Fixed MutableSet's methods to correctly handle

767 ignored by the buffered IO layer anymore.
768
Benjamin Peterson52c36052010-08-21 03:03:22 +0000769- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
770 are not held onto after they are deleted elsewhere.
771
Raymond Hettingera54b2da2010-08-17 19:03:06 +0000772- Issue #9626: the view methods for collections.OrderedDict() were returning
773 the unordered versions inherited from dict. Those methods are now
774 overridden to provide ordered views.

779
Antoine Pitroue1436d12010-08-12 15:25:51 +0000780- Issue #7467: when reading a file from a ZIP archive, its CRC is checked

786 when the underlying raw IO channel was e.g. a socket. Report and original
787 patch by Jason V. Miller.

1193 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

1439 started running. This also fixes the occasional freezes witnessed in
1440 test_httpservers.

Antoine Pitroufc69af12010-04-24 20:04:58 +00001442- Issue #5103: SSL handshake would ignore the socket timeout and block
1443 indefinitely if the other end didn't respond.
1444
Georg Brandlfee0f442010-05-22 21:26:21 +00001445- The do_handshake() method of SSL objects now adjusts the blocking mode of the
1446 SSL structure if necessary (as other methods already do).

Georg Brandlfee0f442010-05-22 21:26:21 +00001456- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of the
1457 string "python" as the *ident*. openlog() arguments are all optional and
1458 keywords.

Philip Jenveyaebbaeb2010-04-06 23:24:45 +00001563- Issue #7301: Add environment variable $PYTHONWARNINGS.
1564
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00001565- Issue #8329: Don't return the same lists from select.select when no fds are
1566 changed.
1567
Georg Brandlfee0f442010-05-22 21:26:21 +00001568- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00001569 on 64-bit machines. The shift count for either left or right shift is
1570 permitted to be up to sys.maxsize.

Georg Brandlfee0f442010-05-22 21:26:21 +00001578- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1579 with a non-empty format string. This is an effort to future-proof user
1580 code. If a derived class does not currently implement __format__ but later
1581 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00001582 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00001583 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00001616- Issue #8257: The Decimal construct now accepts a float instance directly,

Georg Brandlfee0f442010-05-22 21:26:21 +00001633- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1634 InvalidOperation instead of returning False. (Comparisons involving a quiet
1635 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1636 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00001637
Georg Brandlfee0f442010-05-22 21:26:21 +00001638- Issue #2531: Comparison operations between floats and Decimal instances now
1639 return a result based on the numeric values of the operands; previously they
1640 returned an arbitrary result based on the relative ordering of id(float) and
1641 id(Decimal).

Georg Brandlfee0f442010-05-22 21:26:21 +00001644 argument `-` which tells it to read files to compile from stdin. Each line is
1645 read on demand and the named file is compiled immediately. (Original patch by

Georg Brandlfee0f442010-05-22 21:26:21 +00001655- Comparisons using one of <, <=, >, >= between a complex instance and a
1656 Fractions instance now raise TypeError instead of returning True/False. This
1657 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1658 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00002076 file position when calling `truncate()`. It would previously change the file
2077 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002078 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

2081 class used to represent files stored inside an archive. The new
2082 implementation is significantly faster and can be wrapped in a

2174
Georg Brandlba83f822010-03-14 09:50:54 +00002175- The ``__complex__()`` method is now looked up on the class of instances to
2176 make it consistent with other special methods.

Antoine Pitrou5b7139a2010-01-02 21:12:58 +00002178- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
2179 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
2180
Mark Dickinson1b34d252010-01-01 17:27:30 +00002181- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00002182 DeprecationWarning when passed a float argument where an integer was expected.
2183 These functions and methods now raise TypeError instead. The majority of the
2184 effects of this change are in the extension modules, but some core functions
2185 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2186 and many unicode/str methods.

2197 used to drop the time part of the result.
2198
Georg Brandlba83f822010-03-14 09:50:54 +00002199- Issue #1811: Improve accuracy and cross-platform consistency for true division
2200 of integers: the result of a/b is now correctly rounded for ints a and b (at
2201 least on IEEE 754 platforms), and in particular does not depend on the
2202 internal representation of a long.

2386 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2387 the C compiler. There may be a small number of platforms on which correct
2388 operation of this code cannot be guaranteed, so the code is not used: notably,
2389 this applies to platforms where the C double format is not IEEE 754 binary64,
2390 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2391 and Python's configure script is unable to determine how to change the FPU
2392 precision. On these platforms conversions use the platform strtod and dtoa,
2393 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00002395- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2396 uses the correctly-rounded string <-> float conversions described above (when
2397 available), and so produces correctly rounded results that will display nicely
2398 under the float repr. There are two related small changes: (1) round now
2399 accepts any class with an ``__index__()`` method for its second argument (but
2400 no longer accepts floats for the second argument), and (2) an excessively
2401 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2402 raises an exception.

2781 this code path is really executed because I cannot move to such directory on

2808 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

Georg Brandlba83f822010-03-14 09:50:54 +00003979 - Packing a float now always gives a Deprecation Warning. Previously it
3980 only warned for 'I', 'L', '*B', '*H', '*I', '*L'.

Georg Brandlba83f822010-03-14 09:50:54 +00003982 - If x is not an int, long or float, then packing x will always result in
3983 struct.error. Previously an x with an __int__ method could be packed by
3984 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
3985 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
3986 neither __int__ nor __long__, TypeError used to be raised (with a
3987 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
3988 struct.error in other cases.
Mark Dickinson463dc4b2009-07-05 10:01:24 +00003989
Georg Brandlba83f822010-03-14 09:50:54 +00003990 Note: as of Python 2.7 beta 1, the above is out of date. In 2.7 beta 1, any
3991 argument with an __int__ method can be packed, but use of this feature
3992 triggers a DeprecationWarning.

4184
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004185- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4186 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4187 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4188 ``printf`` function, whereas PyString_FromFormat has an independent
4189 implementation and uses "%zd" on all platforms for size_t values.
4190 This makes a difference on win64, where ``printf`` needs "%Id" to display
4191 64bit values.

4197 object; previously an int would be returned for small values. the __long__
4198 method is allowed to return either an int or a long, but the behaviour of

Antoine Pitrou0668c622008-08-26 22:42:08 +00004211 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4212 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4213 when given a tuple of classes as second argument, were looking up
4214 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4215 type object.

Nick Coghland2e09382008-09-11 12:11:06 +00004259- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00004260 return a list or None rather than a custom object.
4261
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00004262- Issue #1638033: Cookie.Morsel gained the httponly attribute.

Brett Cannon1eaf0742008-09-02 01:25:16 +00004286 warnings.catch_warnings() along with some API cleanup. Expanding the tests
4287 for catch_warnings() also led to an improvement in the raising of a
4288 DeprecationWarning related to warnings.warn_explicit().
4289
Benjamin Peterson973e6c22008-09-01 23:12:58 +00004290- The deprecation warnings for the old camelCase threading API were removed.

4312
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00004313- Issue #2975: When compiling several extension modules with Visual Studio 2008
4314 from the same python interpreter, some environment variables would grow
4315 without limit.
4316
Benjamin Peterson37346b22008-08-23 20:27:43 +00004317- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
4318 exploitation of poor argument checking.
4319
Gerhard Häringef2276b2008-09-12 13:54:06 +00004320- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".
4321
Gerhard Häring6e1afcf2008-09-12 18:58:57 +00004322- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
4323 remaining ones have "pysqlite_" prefix.
4324

4333 wrapper for warnings.catch_warnings() that makes it easier to check
4334 that expected warning messages are being reported.
4335

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004354What's New in Python 2.6 beta 3?
4355================================
4356
Barry Warsaw07a4a382008-08-21 01:15:08 +00004357*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004358
4359Core and Builtins
4360-----------------
4361
Guido van Rossumf8402962008-08-20 15:01:50 +00004362- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4363 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4364 extensions do not automatically benefit from the class attribute
4365 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4366 to their tp_flags field if they care. This is a backwards
4367 compatibility feature; in 3.0, all types will use the cache by
4368 default.
4369
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004370- Keyword arguments can now follow starred arguments. (``f(a, *args,
4371 keyword=23)`` is now valid syntax.)
4372
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004373- ctypes function pointers that are COM methods have a boolean True
4374 value again.
4375
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004376- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4377 by denying s# to parse objects that have a releasebuffer procedure,
4378 and introducing s*.
4379
Georg Brandl1e13ea92008-08-11 09:07:59 +00004380- Issue #3537: Fix an assertion failure when an empty but presized dict
4381 object was stored in the freelist.
4382
Mark Dickinsonb6467572008-08-04 21:30:09 +00004383- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4384 ValueError consistently across platforms.
4385
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004386- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4387 (64bit Unix, for example), unichr() would truncate its argument and return
4388 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4389
Neal Norwitze7d8be82008-07-31 17:17:14 +00004390- Apply security patches from Apple.
4391
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004392- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4393 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4394
Antoine Pitrou92f82162008-07-25 22:22:08 +00004395- Issue #1819: function calls with several named parameters are now on
4396 average 35% faster (as measured by pybench).
4397
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004398- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4399 the python debugger steps into a class statement: the free variables (local
4400 variables defined in an outer scope) would be deleted from the outer scope.
4401
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004402- Issue #2620: Overflow checking when allocating or reallocating memory
4403 was not always being done properly in some python types and extension
4404 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4405 all been updated to perform better checks and places in the code that
4406 would previously leak memory on the error path when such an allocation
4407 failed have been fixed.
4408

4410-------
4411
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00004412- Issue #3612: Added some missing basic types in ctypes.wintypes.
4413
Benjamin Petersone977ad42008-08-20 01:42:01 +00004414- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4415 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4416
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004417- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4418 version reported by these tools does not necessarily follow the python
4419 version numbering scheme, so the module is less strict when parsing it.
4420
Nick Coghlanf70385a2008-08-18 12:42:46 +00004421- Issue #2235: Added Py3k warnings for types which will become unhashable
4422 under the stricter __hash__ inheritance rules in 3.0. Several types
4423 which did not meet the rules for hash invariants and were already
4424 unhashable in 3.0 have now been explicitly flagged as unhashable in
4425 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4426 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4427
Brett Cannon88f801d2008-08-18 00:46:22 +00004428- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

4436
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004437- Issue #3575: Incremental decoder's decode function now takes bytearray
4438 by using 's*' instead of 't#'.
4439
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004440- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004441 fails unicode conversion on 2nd parameter. (windows only)
4442
Georg Brandl222e2082010-08-01 22:27:39 +00004443- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004444 in a redirect.
4445
Brett Cannonabe423e2008-08-16 21:47:07 +00004446- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00004447 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004448
Facundo Batistaeb90b782008-08-16 14:44:07 +00004449- Issue #2776: fixed small issue when handling an URL with double slash
4450 after a 302 response in the case of not going through a proxy.
4451
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004452- Issue #2676: in the email package, content-type parsing was hanging on
4453 pathological input because of quadratic or exponential behaviour of a
4454 regular expression.
4455
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004456- Issue #3476: binary buffered reading through the new "io" library is now
4457 thread-safe.
4458
Brett Cannonbf3157b2008-08-14 05:00:03 +00004459- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4460 since mimetools itself is deprecated. Because modules are cached, all
4461 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4462
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004463- Issue #3134: shutil referenced undefined WindowsError symbol.
4464
Robert Schuppenies14646332008-08-10 11:01:53 +00004465- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4466 menu entries were not deleted.
4467
Brett Cannon83e81842008-08-09 23:30:55 +00004468- Copied the implementation of reduce() to _functools.reduce() to have a
4469 version that did not raise a DeprecationWarning under -3.
4470
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004471- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4472 a MemoryError rather than silently stop the iteration.
4473
Guido van Rossum59ce9012008-08-09 14:55:34 +00004474- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4475 to _sre.compile() will now be rejected. This should not affect anybody
4476 since the re.compile() function never generates invalid re-bytecode.
4477
Skip Montanaroa032bf42008-08-08 22:52:51 +00004478- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4479 upon first access it can be automatically initialized from the csv file if
4480 it wasn't initialized during instantiation.
4481
Brett Cannon3aa2a492008-08-06 22:28:09 +00004482- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4483 the reload() built-in has been removed.
4484
Brett Cannon7e30b672008-08-04 21:52:25 +00004485- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00004486 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00004497 asking for a specific length. This problem only affected files opened
4498 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00004499

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00004523- Issue #3394: zipfile.writestr sets external attributes when passed a
4524 file name rather than a ZipInfo instance, so files are extracted with
4525 mode 0600 rather than 000 under Unix.
4526
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00004527- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
4528 argument in python 2.5, this broke code that subclassed Popen to include its

4540 interaction with the tp_hash slot (added in 2.6b2) are now documented
4541
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00004542- Issue #643841: The language reference now provides more detailed
4543 coverage of the lookup process for special methods. The disclaimers
4544 regarding lack of coverage of new-style classes have also been
4545 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00004548What's New in Python 2.6 beta 2?
4549================================
4550
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004551*Release date: 17-Jul-2008*
4552
Raymond Hettingere3ae6552008-06-20 04:18:15 +00004553Core and Builtins
4554-----------------
4555
Georg Brandl3e483f62008-07-16 22:57:41 +00004556- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4557 its methods now allow for items objects that can be converted to
4558 an integer using operator.index().
4559
Mark Dickinson64b7e502008-07-16 09:40:03 +00004560- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4561 produced a ValueError instead of giving the correct float.
4562
Eric Smitha5fa5a22008-07-16 00:11:49 +00004563- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4564 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4565
Mark Dickinson7103aa42008-07-15 19:08:33 +00004566- Issue #3008: the float type has a new instance method 'float.hex'
4567 and a new class method 'float.fromhex' to convert floating-point
4568 numbers to and from hexadecimal strings, respectively.
4569
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004570- Issue #2235: __hash__ is once again inherited by default. To allow
4571 collections.Hashable to remain meaningful in the presence of the
4572 default hash implementation (object.__hash__), it is now possible
4573 to explicit block inheritance of hash by setting __hash__=None at
4574 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4575 level.
4576
Nick Coghlanb028f502008-07-13 14:52:36 +00004577- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4578 the parent module cannot be found while performing an absolute import.
4579 This means that an incorrectly defined __package__ attribute will
4580 now only prevent relative imports in that module rather than causing
4581 all imports from that module to fail.
4582
Nick Coghlan14ff9942008-07-08 14:21:42 +00004583- Issue #2517: Allow unicode messages in Exceptions again by correctly
4584 bypassing the instance dictionary when looking up __unicode__ on
4585 new-style classes.
4586
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00004587- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
4588 set to a custom object whose write() method happens to install
4589 another file in sys.stdout.
4590
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00004591- Issue #3088: Corrected a race condition in classes derived from
4592 threading.local: the first member set by a thread could be saved in
4593 another thread's dictionary.
4594
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004595- Issue #3004: Minor change to slice.indices(): the start and stop
4596 arguments are now treated identically, making the behaviour easier
4597 to describe and understand. For example, slice(None, -10,
4598 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4599 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4600 10, -1).
4601
Georg Brandl278fc502008-07-19 12:46:12 +00004602- Issue #3219: Calling a function with repeated keyword arguments,
4603 f(a=2, a=23), would not cause a syntax error. This was a regression
4604 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00004605
Georg Brandl278fc502008-07-19 12:46:12 +00004606- Issue #2862: Make int and float freelist management consistent with
4607 other freelists. Changes their CompactFreeList apis into
4608 ClearFreeList apis and calls them via gc.collect().

4614 api functions without holding the GIL, which could lead to a fatal
4615 error when they failed.
4616
Martin v. Löwisaabf4042008-08-02 07:20:25 +00004617- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

4626 ForkingPickler.register() to resolve conflict with ctypes.
4627
Vinay Sajip51e65192008-07-18 09:01:10 +00004628- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00004629
Thomas Heller880f5292008-07-15 19:39:38 +00004630- Issue #3313: Fixed a crash when a failed dlopen() call does not set
4631 a valid dlerror() message.

4639
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004640- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00004641
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004642- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
4643 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004644 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004645 content-length. The problem had been corrected in the 2.4 branch, but never
4646 merged into trunk.
4647
Georg Brandle78fbcc2008-07-05 10:13:36 +00004648- Issue #2663: add filtering capability to shutil.copytree().

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004659 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00004660
Nick Coghlanc060b0e2008-07-02 13:09:19 +00004661- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
4662 handling is now the same as that of other special attributes like __name__).
4663
Brett Cannon8bb8fa52008-07-02 01:57:08 +00004664- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
4665 removal in Python 3.0 in favor of urllib2.urlopen().

5118 using the 'warning's machinery in such places as the parser where
5119 use of pure Python code is not possible. Both the ``showarning()``
5120 and ``formatwarning()`` gain an optional 'line' argument which is
5121 not called by default for backwards-compatibility reasons. Setting
5122 ``warnings.showwarning()`` to an implementation that lacks support
5123 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005186- Issue #2550: The approach used by client/server code for obtaining
5187 ports to listen on in network-oriented tests has been refined in an
5188 effort to facilitate running multiple instances of the entire
5189 regression test suite in parallel without issue.
5190 test_support.bind_port() has been fixed such that it will always
5191 return a unique port -- which wasn't always the case with the
5192 previous implementation, especially if socket options had been set
5193 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5194 new implementation of bind_port() will actually raise an exception
5195 if it is passed an AF_INET/SOCK_STREAM socket with either the
5196 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5197 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5198 the socket it's been passed. This currently only applies to
5199 Windows. This option prevents any other sockets from binding to the
5200 host/port we've bound to, thus removing the possibility of the
5201 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5202 when a second SOCK_STREAM socket binds and accepts to a host/port
5203 that's already been bound by another socket. The optional preferred
5204 port parameter to bind_port() has been removed. Under no
5205 circumstances should tests be hard coding ports!
5206
5207 test_support.find_unused_port() has also been introduced, which will
5208 pass a temporary socket object to bind_port() in order to obtain an
5209 unused port. The temporary socket object is then closed and
5210 deleted, and the port is returned. This method should only be used
5211 for obtaining an unused port in order to pass to an external program
5212 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5213 a parameter to a server-oriented class that doesn't give you direct
5214 access to the underlying socket used.
5215
5216 Finally, test_support.HOST has been introduced, which should be used
5217 for the host argument of any relevant socket calls (i.e. bind and
5218 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005219
5220 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005221 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005222 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5223 test_asynchat and test_socket_ssl.
5224
Georg Brandl3ee81df2008-05-17 18:14:43 +00005225 It is now possible for multiple instances of the regression test
5226 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00005505- Added the future_builtins module, which contains hex() and oct().
5506 These are the PEP 3127 version of these functions, designed to be
5507 compatible with the hex() and oct() builtins from Python 3.0. They
5508 differ slightly in their output formats from the existing, unchanged
5509 Python 2.6 builtins. The expected usage of the future_builtins
5510 module is:
5511 from future_builtins import hex, oct
5512
Eric Smith7ef40bf2008-02-20 23:34:22 +00005513- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5514 exponents for exponents with absolute value < 100. Follows C99
5515 standard. This is a change on Windows, which would use 3 digits.
5516 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5517 so that any alterations it does to the resulting string will be
5518 available in stringlib/formatter.h (for float.__format__).
5519
Eric Smith5a3c1352008-02-19 13:21:56 +00005520- Implemented PEP 3101, Advanced String Formatting. This adds a new
5521 builtin format(); a format() method for str and unicode; a
5522 __format__() method to object, str, unicode, int, long, float, and
5523 datetime; the class string.Formatter; and the C API
5524 PyObject_Format().
5525
Georg Brandl3ee81df2008-05-17 18:14:43 +00005526- Fixed several potential crashes, all caused by specially crafted
5527 __del__ methods exploiting objects in temporarily inconsistent
5528 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005529
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005530- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00005531 prevent a possible crash: an Abstract Base Class would try to access
5532 a slot on a registered virtual subclass.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005537- Clear all free lists during a gc.collect() of the highest generation
5538 in order to allow pymalloc to free more arenas. Python may give back
5539 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005540
Georg Brandl3ee81df2008-05-17 18:14:43 +00005541- Issue #2045: Fix an infinite recursion triggered when printing a
5542 subclass of collections.defaultdict, if its default_factory is set
5543 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005544
Christian Heimesf75dbef2008-02-08 00:11:31 +00005545- Fixed a minor memory leak in dictobject.c. The content of the free
5546 list was not freed on interpreter shutdown.
5547
Georg Brandl21e99f42010-03-07 15:23:59 +00005548- Limit free list of method and built-in function objects to 256

Christian Heimes6075a822008-02-06 12:44:34 +00005550
Georg Brandl3ee81df2008-05-17 18:14:43 +00005551- Patch #1953: Added ``sys._compact_freelists()`` and the C API
5552 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005553 to compact the internal free lists of pre-allocted ints and floats.
5554
Georg Brandl3ee81df2008-05-17 18:14:43 +00005555- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5556 calls. Python expected the return type int but the fork familie
5557 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00005558

Georg Brandl3ee81df2008-05-17 18:14:43 +00005571- Patch #1473257: generator objects gain a gi_code attribute. This is
5572 the same object as the func_code attribute of the function that
5573 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005574
Georg Brandl3ee81df2008-05-17 18:14:43 +00005575- Issue #1920: "while 0" statements were completely removed by the
5576 compiler, even in the presence of an "else" clause, which is
5577 supposed to be run when the condition is false. Now the compiler
5578 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005579
Guido van Rossumeead05f2008-01-24 18:21:02 +00005580- A few crashers fixed: weakref_in_del.py (issue #1377858);
5581 loosing_dict_ref.py (issue #1303614, test67.py);
5582 borrowed_ref_[34].py (not in tracker).

5587
Georg Brandl3ee81df2008-05-17 18:14:43 +00005588- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005589 several extension methods and modules do not work without unicode
5590 support.
5591

5594
Georg Brandl14404b62008-01-19 19:27:05 +00005595- Issue #1679: "0x" was taken as a valid integer literal.
5596
Georg Brandl6caad7d2008-01-26 14:19:22 +00005597- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005598 added.
5599
Christian Heimesc94e2b52008-01-14 04:13:37 +00005600- sys.float_info / PyFloat_GetInfo: The floating point information
5601 object was converted from a dict to a specialized structseq object.
5602
Georg Brandl3ee81df2008-05-17 18:14:43 +00005603- Patch #1816: Added sys.flags structseq. It exposes the status of
5604 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005605
Georg Brandl3ee81df2008-05-17 18:14:43 +00005606- Objects/structseq.c: Implemented new structseq representation. The

Georg Brandl3ee81df2008-05-17 18:14:43 +00005610- Patch #1700288: added a type attribute cache that caches method
5611 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005612
Neal Norwitz3fc15b82008-01-10 05:42:58 +00005613- Bug #1776: __import__() no longer accepts filenames on any platform.
5614 The first parameter to __import__() must be a valid module name.

Georg Brandlaed6c662008-01-07 17:25:53 +00005616- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
5617
Georg Brandl3ee81df2008-05-17 18:14:43 +00005618- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5619 envvar and sys.dont_write_bytecode attribute. All these can be set
5620 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005621
Georg Brandl3ee81df2008-05-17 18:14:43 +00005622- Improve some exception messages when Windows fails to load an
5623 extension module. Now we get for example '%1 is not a valid Win32
5624 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00005631- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005632 and INF. float("nan"), float("inf") and float("-inf") now work on
5633 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005635- Compiler now generates simpler and faster code for dictionary
5636 literals. The oparg for BUILD_MAP now indicates an estimated
5637 dictionary size. There is a new opcode, STORE_MAP, for adding
5638 entries to the dictionary.

5650
Nick Coghlanef01d822007-12-03 12:55:17 +00005651- PEP 366: Allow explicit relative imports when executing modules

Georg Brandl3ee81df2008-05-17 18:14:43 +00005667- Patch #1739468: Directories and zipfiles containing a __main__.py
5668 file can now be directly executed by passing their name to the
5669 interpreter. The directory/zipfile is automatically inserted as the
5670 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00005671
Georg Brandl3ee81df2008-05-17 18:14:43 +00005672- Issue #1265: Fix a problem with sys.settrace, if the tracing
5673 function uses a generator expression when at the same time the
5674 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005675
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005676- sets and frozensets now have an isdisjoint() method.
5677

5681
Georg Brandl21e99f42010-03-07 15:23:59 +00005682- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005683 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5684 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005685
Georg Brandl3ee81df2008-05-17 18:14:43 +00005686- Issue #1686386: Tuple's tp_repr did not take into account the
5687 possibility of having a self-referential tuple, which is possible
5688 from C code. Nor did object's tp_str consider that a type's tp_str
5689 could do something that could lead to an inifinite recursion.
5690 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5691 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005692
Georg Brandl3ee81df2008-05-17 18:14:43 +00005693- Issue #1164: It was possible to trigger deadlock when using the
5694 'print' statement to write to a file since the GIL was not released
5695 as needed. Now PyObject_Print() does the right thing along with
5696 various tp_print implementations of the built-in types and those in
5697 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005698
Georg Brandl3ee81df2008-05-17 18:14:43 +00005699- Issue #1147: Exceptions were directly allowing string exceptions in
5700 their throw() method even though string exceptions no longer
5701 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00005702
Georg Brandl3ee81df2008-05-17 18:14:43 +00005703- Issue #1096: Prevent a segfault from getting the repr of a very
5704 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00005705
Brett Cannon1e534b52007-09-07 04:18:30 +00005706- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005707 PyObject_Call() never calling back out to Python code to trigger
5708 recursion depth updates/checks. Required the creation of a static
5709 RuntimeError instance in case normalizing an exception put the
5710 recursion check value past its limit. Fixes crashers
5711 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005712
Georg Brandl3ee81df2008-05-17 18:14:43 +00005713- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00005726- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005727 __*__ attributes. (Some already existed, e.g., __doc__ and
5728 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005729
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005730- Add -3 option to the interpreter to warn about features that are
5731 deprecated and will be changed/removed in Python 3.0.
5732
Georg Brandl2134e752007-05-21 20:34:16 +00005733- Patch #1686487: you can now pass any mapping after '**' in function
5734 calls.
5735
Collin Winter62903052007-05-18 23:11:24 +00005736- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005737 "except E as target:". This is to provide forwards compatibility
5738 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00005739
Brett Cannon229cee22007-05-05 01:34:02 +00005740- Deprecate BaseException.message as per PEP 352.
5741
Georg Brandl3ee81df2008-05-17 18:14:43 +00005742- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00005743 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00005744
Vinay Sajip8549ce32007-05-06 17:53:37 +00005745- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005746 setting a plain string, ie don't expand to single letter identifiers.
5747
Raymond Hettinger13936692007-04-11 18:40:58 +00005748- Request #1191699: Slices can now be pickled.
5749
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005750- Request #1193128: str.translate() now allows a None argument for
5751 translations that only remove characters without re-mapping the
5752 remaining characters.
5753
Georg Brandl5cb76c12007-03-21 09:00:39 +00005754- Patch #1682205: a TypeError while unpacking an iterable is no longer
5755 masked by a generic one with the message "unpack non-sequence".
5756
Neal Norwitzaa754b72007-03-21 06:39:48 +00005757- Remove unused file Python/fmod.c.
5758
Guido van Rossum143b5642007-03-23 04:58:42 +00005759- Bug #1683368: The object.__init__() and object.__new__() methods are
5760 now stricter in rejecting excess arguments. The only time when
5761 either allows excess arguments is when it is not overridden and the
5762 other one is. For backwards compatibility, when both are
5763 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005764 warning later). Also, type.__init__() insists on the same signature
5765 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005766
Georg Brandl3ee81df2008-05-17 18:14:43 +00005767- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5768 object to complex using its __complex__() method before falling back
5769 to the __float__() method. Therefore, the functions in the cmath
5770 module now can operate on objects that define a __complex__()
5771 method.
Georg Brandl2b869942007-03-17 16:08:45 +00005772
Georg Brandl3ee81df2008-05-17 18:14:43 +00005773- Patch #1623563: allow __class__ assignment for classes with
5774 __slots__. The old and the new class are still required to have the
5775 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00005776
Georg Brandl3ee81df2008-05-17 18:14:43 +00005777- Patch #1642547: Fix an error/crash when encountering syntax errors

5781 ``object.__reduce_ex__()`` is called with an object that is faking
5782 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00005783
Georg Brandl3ee81df2008-05-17 18:14:43 +00005784- Patch #1680015: Don't modify __slots__ tuple if it contains an

5788
Georg Brandl7b9c5552007-03-12 14:30:05 +00005789- Bug #1678647: write a newline after printing an exception in any
5790 case, even when converting the value to a string failed.
5791
Georg Brandl871f1bc2007-03-12 13:17:36 +00005792- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005793 its argument, if it exists. If not, it will work like before. This
5794 allows customizing the output of dir() in the presence of a
5795 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00005796
Collin Winter276887b2007-03-12 16:11:39 +00005797- Patch #922167: Python no longer segfaults when faced with infinitely
5798 self-recursive reload() calls (as reported by bug #742342).
5799
Georg Brandl3ee81df2008-05-17 18:14:43 +00005800- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00005803- Patch #1491866: change the complex() constructor to allow
5804 parthensized forms. This means complex(repr(x)) now works instead of
5805 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005806
Georg Brandlaa2321b2007-03-07 00:40:28 +00005807- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005808 makes the filenames the warning module prints much more sensible
5809 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00005810

5812 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00005813 variable is given, but break into the interactive interpreter just
5814 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00005822- Patch #1674228: when assigning a slice (old-style), check for the
5823 sq_ass_slice instead of the sq_slice slot.
5824
Georg Brandl3ee81df2008-05-17 18:14:43 +00005825- When printing an unraisable error, don't print exceptions. before
5826 the name. This duplicates the behavior whening normally printing
5827 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006360 AttributeError instead of an IOError when the server's response
6361 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00006362

Georg Brandl3ee81df2008-05-17 18:14:43 +00006367- Patch #1429539: pdb now correctly initializes the __main__ module
6368 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00006369 correctly now.
6370

6377
Georg Brandl3ee81df2008-05-17 18:14:43 +00006378- Patch #1530482: add pydoc.render_doc() which returns the

6393
Georg Brandl92a6bae2007-03-13 17:43:32 +00006394- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00006395 are set for invalid interpolation sequences that would lead to
6396 errors on reading back those values.

6437

6439 returned string up to the first NUL character.

6450
Georg Brandl3ee81df2008-05-17 18:14:43 +00006451- unittest now verifies more of its assumptions. In particular,
6452 TestCase and TestSuite subclasses (not instances) are no longer
6453 accepted in TestSuite.addTest(). This should cause no
6454 incompatibility since it never made sense with ordinary subclasses
6455 -- the failure just occurred later, with a more cumbersome
6456 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00006457

6466
Georg Brandl3ee81df2008-05-17 18:14:43 +00006467- Patch #1673619: setup.py identifies extension modules it doesn't

6827 complex, tuple, list, dict, set, and frozenset. Formerly, it would

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00006844- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00006845 time so that opening a database previously created with the DB_DUP
6846 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6847 opens. Specifically: dictionary assignment to a DB object will
6848 replace all values for a given key when the database allows
6849 duplicate values. DB users should use DB.put(k, v) when they want
6850 to store duplicates; not DB[k] = v.

6857 characters with ASCII value less than 32. Also, it correctly quotes
6858 dots only if they occur on a single line, as opposed to the previous
6859 behavior of quoting dots if they are the second character of any
6860 line.

7206 of w# format code incorrectly truncated the length to an int, even
7207 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
7208 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007238- Added case insensitive comparison methods ``PyOS_stricmp(char*,
7239 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
