Mark Dickinson4ca7c3c2010-05-30 13:18:10 +0000329- Issue #8748: Fix two issues with comparisons between complex and integer
330 objects. (1) The comparison could incorrectly return True in some cases
331 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Georg Brandlfee0f442010-05-22 21:26:21 +0000594- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of the
595 string "python" as the *ident*. openlog() arguments are all optional and
596 keywords.
Sean Reifscheiderf6ce3cb2010-04-23 08:31:55 +0000597

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +0000676 (Optimization was unintentionally turned on in gcc --with-pydebug builds in
677 2.7 beta1 as a result of the issue #1628484 fix, combined with autoconf's
678 strange choice of default CFLAGS produced by AC_PROG_CC for gcc.)

699-----------------
700
Philip Jenveyaebbaeb2010-04-06 23:24:45 +0000701- Issue #7301: Add environment variable $PYTHONWARNINGS.
702
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +0000703- Issue #8329: Don't return the same lists from select.select when no fds are
704 changed.
705
Georg Brandlfee0f442010-05-22 21:26:21 +0000706- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +0000707 on 64-bit machines. The shift count for either left or right shift is
708 permitted to be up to sys.maxsize.
709
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +0000710- Ensure that tokenization of identifiers is not affected by locale.

Benjamin Peterson1c7c11e2010-04-03 01:28:57 +0000714- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
715
Georg Brandlfee0f442010-05-22 21:26:21 +0000716- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
717 with a non-empty format string. This is an effort to future-proof user
718 code. If a derived class does not currently implement __format__ but later
719 adds its own __format__, it would most likely break user code that had
720 supplied a format string. This will be changed to a DeprecationWaring in
721 Python 3.3 and it will be an error in Python 3.4.

Antoine Pitrouf9de5342010-04-05 21:35:07 +0000748- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
Georg Brandlfee0f442010-05-22 21:26:21 +0000749 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO` and

Georg Brandlfee0f442010-05-22 21:26:21 +0000754- Issue #8257: The Decimal construct now accepts a float instance directly,
755 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +0000756

759
Raymond Hettinger34c35b22010-04-03 10:22:00 +0000760- collections.Counter() now supports a subtract() method.
761
Georg Brandlfee0f442010-05-22 21:26:21 +0000762- The functools module now has a total_ordering() class decorator to simplify
763 the specification of rich comparisons.

Georg Brandlfee0f442010-05-22 21:26:21 +0000765- The functools module also adds cmp_to_key() as a tool to transition old-style

Georg Brandlfee0f442010-05-22 21:26:21 +0000771- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
772 InvalidOperation instead of returning False. (Comparisons involving a quiet
773 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
774 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +0000775
Georg Brandlfee0f442010-05-22 21:26:21 +0000776- Issue #2531: Comparison operations between floats and Decimal instances now
777 return a result based on the numeric values of the operands; previously they
778 returned an arbitrary result based on the relative ordering of id(float) and
779 id(Decimal).
Mark Dickinson99d80962010-04-02 08:53:22 +0000780
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000781- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +0000782 argument `-` which tells it to read files to compile from stdin. Each line is
783 read on demand and the named file is compiled immediately. (Original patch by
784 Piotr Ożarowski).

Georg Brandlfee0f442010-05-22 21:26:21 +0000793- Comparisons using one of <, <=, >, >= between a complex instance and a
794 Fractions instance now raise TypeError instead of returning True/False. This
795 makes Fraction <=> complex comparisons consistent with int <=> complex, float
796 <=> complex, and complex <=> complex comparisons.

Georg Brandlfee0f442010-05-22 21:26:21 +0000903 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour was
904 inconsistent: __int__ was used for some integer codes but not for others, and
905 the set of integer codes for which it was used differed between native packing
906 and standard packing.)

Georg Brandlba83f822010-03-14 09:50:54 +00001149- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
1150 and add the additional members returned in an OSVERSIONINFOEX structure. The
1151 new members are service_pack_major, service_pack_minor, suite_mask, and

Georg Brandlba83f822010-03-14 09:50:54 +00001154- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
1155 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
1156 returning NULL. The macro now returns a statically allocated empty string
1157 instead.

1167 strings,
1168 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
1169 numeric strings corresponding to subnormal values,
1170 (3) a memory leak for some values large enough to cause overflow, and
1171 (4) a number of flaws that could lead to incorrectly rounded results.

Antoine Pitroud840e512010-02-04 20:20:18 +00001202- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00001203 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00001204 Also, raise ValueError rather than TypeError when an unknown TIPC address
1205 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001209- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00001210 file position when calling `truncate()`. It would previously change the file
1211 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001212 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
1213
Georg Brandlba83f822010-03-14 09:50:54 +00001214- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
1215 class used to represent files stored inside an archive. The new
1216 implementation is significantly faster and can be wrapped in a
1217 ``io.BufferedReader`` object for more speedups. It also solves an issue
1218 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00001229- Issue #7748: Since unicode values are supported for some metadata options in
1230 Distutils, the DistributionMetadata get_* methods will now return an utf-8
1231 encoded string for them. This ensures that the upload and register commands
1232 send the correct values to PyPI without any error.

Benjamin Peterson4f51baf2009-12-05 18:40:02 +00001301What's New in Python 2.7 alpha 2?
1302=================================
1303
Benjamin Petersonaa7e51f2010-01-09 16:34:06 +00001304*Release date: 2010-01-09*

1307-----------------
1308
Georg Brandlba83f822010-03-14 09:50:54 +00001309- The ``__complex__()`` method is now looked up on the class of instances to
1310 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00001311
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00001312- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
1313 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
1314
Mark Dickinson1b34d252010-01-01 17:27:30 +00001315- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001316 DeprecationWarning when passed a float argument where an integer was expected.
1317 These functions and methods now raise TypeError instead. The majority of the
1318 effects of this change are in the extension modules, but some core functions
1319 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1320 and many unicode/str methods.
Mark Dickinson1b34d252010-01-01 17:27:30 +00001321
Benjamin Peterson0f02d392009-12-30 19:34:10 +00001322- Issue #7604: Deleting an unset slotted attribute did not raise an
1323 AttributeError.
1324
Georg Brandlba83f822010-03-14 09:50:54 +00001325- Issue #7534: Fix handling of IEEE specials (infinities, nans, negative zero)
1326 in ** operator. The behaviour now conforms to that described in C99 Annex F.

Georg Brandlba83f822010-03-14 09:50:54 +00001328- Issue #7579: The msvcrt module now has docstrings for all its functions.
Amaury Forgeot d'Arcc8a2ce72009-12-29 23:06:17 +00001329
Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +00001330- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
1331 used to drop the time part of the result.
1332
Georg Brandlba83f822010-03-14 09:50:54 +00001333- Issue #1811: Improve accuracy and cross-platform consistency for true division
1334 of integers: the result of a/b is now correctly rounded for ints a and b (at
1335 least on IEEE 754 platforms), and in particular does not depend on the
1336 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +00001337
Georg Brandlba83f822010-03-14 09:50:54 +00001338- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the
1339 same message when only ``__str__()`` (and not ``__unicode__()``) is overridden
1340 in the subclass.
Ezio Melottif84caf42009-12-24 22:25:17 +00001341
Georg Brandlba83f822010-03-14 09:50:54 +00001342- Issue #6834: Replace the implementation for the 'python' and 'pythonw'
Ronald Oussoren92919a62009-12-24 13:30:58 +00001343 executables on OSX.
1344
Georg Brandlba83f822010-03-14 09:50:54 +00001345 These executables now work properly with the arch(1) command: ``arch -ppc
1346 python`` will start a universal binary version of python in PPC mode (unlike
1347 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +00001348
Georg Brandlba83f822010-03-14 09:50:54 +00001349- Issue #1680159: Unicode coercion during an 'in' operation no longer masks the
1350 underlying error when the coercion fails for the left hand operand.
R. David Murray0a0a1a82009-12-14 16:28:26 +00001351
Benjamin Peterson4895af42009-12-13 16:36:53 +00001352- Issue #7491: Metaclass's __cmp__ method was ignored.
1353
Georg Brandlba83f822010-03-14 09:50:54 +00001354- Issue #7466: Segmentation fault when the garbage collector is called in the
1355 middle of populating a tuple. Patch by Florent Xicluna.

Georg Brandlba83f822010-03-14 09:50:54 +00001361- Issue #6963: Added "maxtasksperchild" argument to ``multiprocessing.Pool``,
1362 allowing for a maximum number of tasks within the pool to be completed by the
1363 worker before that worker is terminated, and a new one created to replace it.
Jesse Noller654ade32010-01-27 03:05:57 +00001364
Georg Brandlba83f822010-03-14 09:50:54 +00001365- Issue #7617: Make sure distutils.unixccompiler.UnixCCompiler recognizes gcc

1367 Arfrever.
Tarek Ziadéc25417f2010-01-08 23:42:23 +00001368
Antoine Pitrou80157252010-01-08 19:20:17 +00001369- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
Georg Brandlba83f822010-03-14 09:50:54 +00001370 renaming of `cPickle` to `pickle`. The warning was annoying since there's no
1371 alternative to cPickle if you care about performance. Patch by Florent
Antoine Pitrou80157252010-01-08 19:20:17 +00001372 Xicluna.

Gregory P. Smith79a3eb12010-01-03 01:29:44 +00001389
Georg Brandlba83f822010-03-14 09:50:54 +00001390- Issue #5511: ``zipfile.ZipFile`` can now be used as a context manager.
Ezio Melotti569e61f2009-12-30 06:14:51 +00001391 Initial patch by Brian Curtin.
1392
Georg Brandlba83f822010-03-14 09:50:54 +00001393- Distutils now correctly identifies the build architecture as "x86_64" when
1394 building on OSX 10.6 without "-arch" flags.
Ronald Oussorenca8e7ec2009-12-24 14:50:35 +00001395

Georg Brandlba83f822010-03-14 09:50:54 +00001399- Issue #7552: Removed line feed in the base64 Authorization header in the
1400 Distutils upload command to avoid an error when PyPI reads it. This occurs on
1401 long passwords. Initial patch by JP St. Pierre.
Tarek Ziadé2421d562009-12-20 23:23:34 +00001402
Georg Brandlba83f822010-03-14 09:50:54 +00001403- Issue #7231: urllib2 cannot handle https with proxy requiring auth. Patch by

Benjamin Petersonddd392c2009-12-13 19:19:07 +00001406- Issue #7349: Make methods of file objects in the io module accept None as an
1407 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
1408 the same as passing no argument.
1409
Georg Brandlba83f822010-03-14 09:50:54 +00001410- Issue #7348: ``StringIO.StringIO.readline(-1)`` now acts as if it got no
1411 argument like other file objects.
Benjamin Petersonc4771d22009-12-13 17:31:31 +00001412

1430 to ``PyLong_AsLongAndOverflow()``.
Mark Dickinsona36507c2010-01-30 10:08:33 +00001431
Georg Brandlba83f822010-03-14 09:50:54 +00001432- Issue #5080: The argument parsing functions ``PyArg_ParseTuple()``,
1433 ``PyArg_ParseTupleAndKeywords()``, ``PyArg_VaParse()``,
1434 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept
1435 float arguments for integer format codes (other than 'L'): previously an
1436 attempt to pass a float resulted in a DeprecationWarning; now it gives a
1437 TypeError. For the 'L' format code (which previously had no warning) there is
1438 now a DeprecationWarning.

Georg Brandlba83f822010-03-14 09:50:54 +00001450- Issue #7609: Add a ``--with-system-expat`` option that causes the system's
1451 expat library to be used for the pyexpat module instead of the one included
1452 with Python.

1487 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001488

Georg Brandlba83f822010-03-14 09:50:54 +00001503- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1504 decimal string that's guaranteed to round back to x under correct rounding
1505 (with round-half-to-even rounding mode). Previously it gave a string based on
1506 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1507 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1508 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001509
Georg Brandlba83f822010-03-14 09:50:54 +00001510- Issue #7117: On almost all platforms: float-to-string and string-to-float
1511 conversions within Python are now correctly rounded. Places these conversions
1512 occur include: str for floats and complex numbers; the float and complex
1513 constructors; old-style and new-style numeric formatting; serialization and
1514 deserialization of floats and complex numbers using marshal, pickle and json;
1515 parsing of float and imaginary literals in Python code; Decimal-to-float
1516 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001517
Georg Brandlba83f822010-03-14 09:50:54 +00001518 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1519 providing correctly-rounded strtod and dtoa C functions. This code is
1520 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1521 the C compiler. There may be a small number of platforms on which correct
1522 operation of this code cannot be guaranteed, so the code is not used: notably,
1523 this applies to platforms where the C double format is not IEEE 754 binary64,
1524 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1525 and Python's configure script is unable to determine how to change the FPU
1526 precision. On these platforms conversions use the platform strtod and dtoa,
1527 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001528
Georg Brandlba83f822010-03-14 09:50:54 +00001529- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1530 uses the correctly-rounded string <-> float conversions described above (when
1531 available), and so produces correctly rounded results that will display nicely
1532 under the float repr. There are two related small changes: (1) round now
1533 accepts any class with an ``__index__()`` method for its second argument (but
1534 no longer accepts floats for the second argument), and (2) an excessively
1535 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1536 raises an exception.

Philip Jenveyfab8be22009-11-17 02:42:26 +00001538- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
1539

1915 this code path is really executed because I cannot move to such directory on

1942 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003319- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3320 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3321 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3322 ``printf`` function, whereas PyString_FromFormat has an independent
3323 implementation and uses "%zd" on all platforms for size_t values.
3324 This makes a difference on win64, where ``printf`` needs "%Id" to display
3325 64bit values.

Antoine Pitrou0668c622008-08-26 22:42:08 +00003345 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__

Brett Cannon1eaf0742008-09-02 01:25:16 +00003420 warnings.catch_warnings() along with some API cleanup. Expanding the tests
3421 for catch_warnings() also led to an improvement in the raising of a
3422 DeprecationWarning related to warnings.warn_explicit().
3423
Benjamin Peterson973e6c22008-09-01 23:12:58 +00003424- The deprecation warnings for the old camelCase threading API were removed.

3446
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00003447- Issue #2975: When compiling several extension modules with Visual Studio 2008
3448 from the same python interpreter, some environment variables would grow
3449 without limit.
3450
Benjamin Peterson37346b22008-08-23 20:27:43 +00003451- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
3452 exploitation of poor argument checking.
3453
Gerhard Häringef2276b2008-09-12 13:54:06 +00003454- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003488What's New in Python 2.6 beta 3?
3489================================
3490
Barry Warsaw07a4a382008-08-21 01:15:08 +00003491*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003492
3493Core and Builtins
3494-----------------
3495
Guido van Rossumf8402962008-08-20 15:01:50 +00003496- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3497 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3498 extensions do not automatically benefit from the class attribute
3499 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3500 to their tp_flags field if they care. This is a backwards
3501 compatibility feature; in 3.0, all types will use the cache by
3502 default.
3503
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003504- Keyword arguments can now follow starred arguments. (``f(a, *args,
3505 keyword=23)`` is now valid syntax.)
3506
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003507- ctypes function pointers that are COM methods have a boolean True
3508 value again.
3509
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003510- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3511 by denying s# to parse objects that have a releasebuffer procedure,
3512 and introducing s*.
3513
Georg Brandl1e13ea92008-08-11 09:07:59 +00003514- Issue #3537: Fix an assertion failure when an empty but presized dict
3515 object was stored in the freelist.
3516
Mark Dickinsonb6467572008-08-04 21:30:09 +00003517- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3518 ValueError consistently across platforms.
3519
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003520- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3521 (64bit Unix, for example), unichr() would truncate its argument and return
3522 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3523
Neal Norwitze7d8be82008-07-31 17:17:14 +00003524- Apply security patches from Apple.
3525
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003526- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3527 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3528
Antoine Pitrou92f82162008-07-25 22:22:08 +00003529- Issue #1819: function calls with several named parameters are now on
3530 average 35% faster (as measured by pybench).
3531
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003532- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3533 the python debugger steps into a class statement: the free variables (local
3534 variables defined in an outer scope) would be deleted from the outer scope.
3535
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003536- Issue #2620: Overflow checking when allocating or reallocating memory
3537 was not always being done properly in some python types and extension
3538 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3539 all been updated to perform better checks and places in the code that
3540 would previously leak memory on the error path when such an allocation
3541 failed have been fixed.
3542
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003543Library
3544-------
3545
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003546- Issue #3612: Added some missing basic types in ctypes.wintypes.
3547
Benjamin Petersone977ad42008-08-20 01:42:01 +00003548- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3549 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3550
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003551- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3552 version reported by these tools does not necessarily follow the python
3553 version numbering scheme, so the module is less strict when parsing it.
3554
Nick Coghlanf70385a2008-08-18 12:42:46 +00003555- Issue #2235: Added Py3k warnings for types which will become unhashable
3556 under the stricter __hash__ inheritance rules in 3.0. Several types
3557 which did not meet the rules for hash invariants and were already
3558 unhashable in 3.0 have now been explicitly flagged as unhashable in
3559 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3560 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3561
Brett Cannon88f801d2008-08-18 00:46:22 +00003562- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3563 imported into the module but exposed as part of the module's API.
3564
Brett Cannon7b96f072008-08-18 00:41:11 +00003565- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3566
Brett Cannon46225e72008-08-18 00:36:52 +00003567- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00003569- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
3570
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003571- Issue #3575: Incremental decoder's decode function now takes bytearray
3572 by using 's*' instead of 't#'.
3573
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003574- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003575 fails unicode conversion on 2nd parameter. (windows only)
3576
Georg Brandl222e2082010-08-01 22:27:39 +00003577- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00003578 in a redirect.
3579
Brett Cannonabe423e2008-08-16 21:47:07 +00003580- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003581 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003582
Facundo Batistaeb90b782008-08-16 14:44:07 +00003583- Issue #2776: fixed small issue when handling an URL with double slash
3584 after a 302 response in the case of not going through a proxy.
3585
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003586- Issue #2676: in the email package, content-type parsing was hanging on
3587 pathological input because of quadratic or exponential behaviour of a
3588 regular expression.
3589
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003590- Issue #3476: binary buffered reading through the new "io" library is now
3591 thread-safe.
3592
Brett Cannonbf3157b2008-08-14 05:00:03 +00003593- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3594 since mimetools itself is deprecated. Because modules are cached, all
3595 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3596
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003597- Issue #3134: shutil referenced undefined WindowsError symbol.
3598
Robert Schuppenies14646332008-08-10 11:01:53 +00003599- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3600 menu entries were not deleted.
3601
Brett Cannon83e81842008-08-09 23:30:55 +00003602- Copied the implementation of reduce() to _functools.reduce() to have a
3603 version that did not raise a DeprecationWarning under -3.
3604
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003605- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3606 a MemoryError rather than silently stop the iteration.
3607
Guido van Rossum59ce9012008-08-09 14:55:34 +00003608- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3609 to _sre.compile() will now be rejected. This should not affect anybody
3610 since the re.compile() function never generates invalid re-bytecode.
3611
Skip Montanaroa032bf42008-08-08 22:52:51 +00003612- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3613 upon first access it can be automatically initialized from the csv file if
3614 it wasn't initialized during instantiation.
3615
Brett Cannon3aa2a492008-08-06 22:28:09 +00003616- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3617 the reload() built-in has been removed.
3618
Brett Cannon7e30b672008-08-04 21:52:25 +00003619- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003620 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00003631 asking for a specific length. This problem only affected files opened
3632 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003633

3658 file name rather than a ZipInfo instance, so files are extracted with
3659 mode 0600 rather than 000 under Unix.
3660
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003661- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
3662 argument in python 2.5, this broke code that subclassed Popen to include its
3663 own poll method. Fixed my moving _deadstate to an _internal_poll method.

3678 regarding lack of coverage of new-style classes have also been
3679 removed, since the coverage is now fairly reasonable.

Georg Brandl3e483f62008-07-16 22:57:41 +00003690- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3691 its methods now allow for items objects that can be converted to
3692 an integer using operator.index().
3693
Mark Dickinson64b7e502008-07-16 09:40:03 +00003694- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3695 produced a ValueError instead of giving the correct float.
3696
Eric Smitha5fa5a22008-07-16 00:11:49 +00003697- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3698 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3699
Mark Dickinson7103aa42008-07-15 19:08:33 +00003700- Issue #3008: the float type has a new instance method 'float.hex'
3701 and a new class method 'float.fromhex' to convert floating-point
3702 numbers to and from hexadecimal strings, respectively.
3703
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003704- Issue #2235: __hash__ is once again inherited by default. To allow
3705 collections.Hashable to remain meaningful in the presence of the
3706 default hash implementation (object.__hash__), it is now possible
3707 to explicit block inheritance of hash by setting __hash__=None at
3708 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3709 level.
3710
Nick Coghlanb028f502008-07-13 14:52:36 +00003711- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3712 the parent module cannot be found while performing an absolute import.
3713 This means that an incorrectly defined __package__ attribute will
3714 now only prevent relative imports in that module rather than causing
3715 all imports from that module to fail.
3716
Nick Coghlan14ff9942008-07-08 14:21:42 +00003717- Issue #2517: Allow unicode messages in Exceptions again by correctly

3727 another thread's dictionary.
3728
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003729- Issue #3004: Minor change to slice.indices(): the start and stop
3730 arguments are now treated identically, making the behaviour easier
3731 to describe and understand. For example, slice(None, -10,
3732 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3733 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3734 10, -1).

Georg Brandl278fc502008-07-19 12:46:12 +00003736- Issue #3219: Calling a function with repeated keyword arguments,
3737 f(a=2, a=23), would not cause a syntax error. This was a regression
3738 from 2.4 caused by the switch to the new compiler.

3777 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003778 wrong because the actual transmitted size could differ from the

Georg Brandl3ee81df2008-05-17 18:14:43 +00004250- Issue #1631171: Re-implement the 'warnings' module in C (the
4251 original Python code has been kept as backup). This will allow for
4252 using the 'warning's machinery in such places as the parser where
4253 use of pure Python code is not possible. Both the ``showarning()``
4254 and ``formatwarning()`` gain an optional 'line' argument which is
4255 not called by default for backwards-compatibility reasons. Setting
4256 ``warnings.showwarning()`` to an implementation that lacks support
4257 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004320- Issue #2550: The approach used by client/server code for obtaining
4321 ports to listen on in network-oriented tests has been refined in an
4322 effort to facilitate running multiple instances of the entire
4323 regression test suite in parallel without issue.
4324 test_support.bind_port() has been fixed such that it will always
4325 return a unique port -- which wasn't always the case with the
4326 previous implementation, especially if socket options had been set
4327 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4328 new implementation of bind_port() will actually raise an exception
4329 if it is passed an AF_INET/SOCK_STREAM socket with either the
4330 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4331 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4332 the socket it's been passed. This currently only applies to
4333 Windows. This option prevents any other sockets from binding to the
4334 host/port we've bound to, thus removing the possibility of the
4335 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4336 when a second SOCK_STREAM socket binds and accepts to a host/port
4337 that's already been bound by another socket. The optional preferred
4338 port parameter to bind_port() has been removed. Under no
4339 circumstances should tests be hard coding ports!
4340
4341 test_support.find_unused_port() has also been introduced, which will
4342 pass a temporary socket object to bind_port() in order to obtain an
4343 unused port. The temporary socket object is then closed and
4344 deleted, and the port is returned. This method should only be used
4345 for obtaining an unused port in order to pass to an external program
4346 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4347 a parameter to a server-oriented class that doesn't give you direct
4348 access to the underlying socket used.
4349
4350 Finally, test_support.HOST has been introduced, which should be used
4351 for the host argument of any relevant socket calls (i.e. bind and
4352 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004353
4354 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004355 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004356 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4357 test_asynchat and test_socket_ssl.
4358
Georg Brandl3ee81df2008-05-17 18:14:43 +00004359 It is now possible for multiple instances of the regression test
4360 suite to run in parallel without issue.

4516 processor information on Windows XP and later. As a result,
Marc-André Lemburga1867752008-03-20 18:08:00 +00004517 platform.machine() and platform.processor() will report this
4518 information as well.

Facundo Batistafc2d0102008-02-23 12:01:13 +00004638
Eric Smitha73fbe72008-02-23 03:09:44 +00004639- Added the future_builtins module, which contains hex() and oct().
4640 These are the PEP 3127 version of these functions, designed to be
4641 compatible with the hex() and oct() builtins from Python 3.0. They
4642 differ slightly in their output formats from the existing, unchanged
4643 Python 2.6 builtins. The expected usage of the future_builtins
4644 module is:
4645 from future_builtins import hex, oct
4646
Eric Smith7ef40bf2008-02-20 23:34:22 +00004647- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4648 exponents for exponents with absolute value < 100. Follows C99
4649 standard. This is a change on Windows, which would use 3 digits.
4650 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4651 so that any alterations it does to the resulting string will be
4652 available in stringlib/formatter.h (for float.__format__).
4653
Eric Smith5a3c1352008-02-19 13:21:56 +00004654- Implemented PEP 3101, Advanced String Formatting. This adds a new
4655 builtin format(); a format() method for str and unicode; a
4656 __format__() method to object, str, unicode, int, long, float, and
4657 datetime; the class string.Formatter; and the C API
4658 PyObject_Format().
4659
Georg Brandl3ee81df2008-05-17 18:14:43 +00004660- Fixed several potential crashes, all caused by specially crafted
4661 __del__ methods exploiting objects in temporarily inconsistent
4662 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00004663
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004664- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00004665 prevent a possible crash: an Abstract Base Class would try to access
4666 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00004667
Georg Brandl3ee81df2008-05-17 18:14:43 +00004668- Fixed repr() and str() of complex numbers with infinity or nan as
4669 real or imaginary part.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004671- Clear all free lists during a gc.collect() of the highest generation
4672 in order to allow pymalloc to free more arenas. Python may give back
4673 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004674
Georg Brandl3ee81df2008-05-17 18:14:43 +00004675- Issue #2045: Fix an infinite recursion triggered when printing a
4676 subclass of collections.defaultdict, if its default_factory is set
4677 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004678
Christian Heimesf75dbef2008-02-08 00:11:31 +00004679- Fixed a minor memory leak in dictobject.c. The content of the free
4680 list was not freed on interpreter shutdown.
4681
Georg Brandl21e99f42010-03-07 15:23:59 +00004682- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004683 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004684
Georg Brandl3ee81df2008-05-17 18:14:43 +00004685- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4686 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004687 to compact the internal free lists of pre-allocted ints and floats.
4688
Georg Brandl3ee81df2008-05-17 18:14:43 +00004689- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4690 calls. Python expected the return type int but the fork familie
4691 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004692
Georg Brandl3ee81df2008-05-17 18:14:43 +00004693- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4694 appear in the same code unit.

4703 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004704
Georg Brandl3ee81df2008-05-17 18:14:43 +00004705- Patch #1473257: generator objects gain a gi_code attribute. This is
4706 the same object as the func_code attribute of the function that
4707 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004708
Georg Brandl3ee81df2008-05-17 18:14:43 +00004709- Issue #1920: "while 0" statements were completely removed by the
4710 compiler, even in the presence of an "else" clause, which is
4711 supposed to be run when the condition is false. Now the compiler
4712 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004713
Guido van Rossumeead05f2008-01-24 18:21:02 +00004714- A few crashers fixed: weakref_in_del.py (issue #1377858);
4715 loosing_dict_ref.py (issue #1303614, test67.py);
4716 borrowed_ref_[34].py (not in tracker).
4717
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004718- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004719 suppressed while an extension is loaded by calling SetErrorMode in
4720 dynload_win.c. The error is still reported properly.
4721
Georg Brandl3ee81df2008-05-17 18:14:43 +00004722- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004723 several extension methods and modules do not work without unicode
4724 support.
4725
Georg Brandl26543b12008-01-21 18:36:51 +00004726- Issue #1882: when compiling code from a string, encoding cookies in the
4727 second line of code were not always recognized correctly.
4728
Georg Brandl14404b62008-01-19 19:27:05 +00004729- Issue #1679: "0x" was taken as a valid integer literal.
4730
Georg Brandl6caad7d2008-01-26 14:19:22 +00004731- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004732 added.
4733
Christian Heimesc94e2b52008-01-14 04:13:37 +00004734- sys.float_info / PyFloat_GetInfo: The floating point information
4735 object was converted from a dict to a specialized structseq object.
4736
Georg Brandl3ee81df2008-05-17 18:14:43 +00004737- Patch #1816: Added sys.flags structseq. It exposes the status of
4738 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004739
Georg Brandl3ee81df2008-05-17 18:14:43 +00004740- Objects/structseq.c: Implemented new structseq representation. The
4741 patch makes structseqs (e.g. the return value of os.stat) more
4742 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004743
Georg Brandl3ee81df2008-05-17 18:14:43 +00004744- Patch #1700288: added a type attribute cache that caches method
4745 accesses, resulting in speedups in heavily object-oriented code.

4751
Georg Brandl3ee81df2008-05-17 18:14:43 +00004752- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4753 envvar and sys.dont_write_bytecode attribute. All these can be set
4754 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004755
Georg Brandl3ee81df2008-05-17 18:14:43 +00004756- Improve some exception messages when Windows fails to load an
4757 extension module. Now we get for example '%1 is not a valid Win32

4771 dictionary size. There is a new opcode, STORE_MAP, for adding
4772 entries to the dictionary.

4815
Georg Brandl21e99f42010-03-07 15:23:59 +00004816- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004817 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4818 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004819
Georg Brandl3ee81df2008-05-17 18:14:43 +00004820- Issue #1686386: Tuple's tp_repr did not take into account the
4821 possibility of having a self-referential tuple, which is possible
4822 from C code. Nor did object's tp_str consider that a type's tp_str
4823 could do something that could lead to an inifinite recursion.
4824 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4825 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004826
Georg Brandl3ee81df2008-05-17 18:14:43 +00004827- Issue #1164: It was possible to trigger deadlock when using the
4828 'print' statement to write to a file since the GIL was not released
4829 as needed. Now PyObject_Print() does the right thing along with
4830 various tp_print implementations of the built-in types and those in
4831 the collections module.

Brett Cannon1e534b52007-09-07 04:18:30 +00004840- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004841 PyObject_Call() never calling back out to Python code to trigger
4842 recursion depth updates/checks. Required the creation of a static
4843 RuntimeError instance in case normalizing an exception put the
4844 recursion check value past its limit. Fixes crashers

Georg Brandl3ee81df2008-05-17 18:14:43 +00004861 __*__ attributes. (Some already existed, e.g., __doc__ and
4862 __name__.)

4868 calls.
4869
Collin Winter62903052007-05-18 23:11:24 +00004870- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004871 "except E as target:". This is to provide forwards compatibility
4872 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00004879- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004880 setting a plain string, ie don't expand to single letter identifiers.
4881
Raymond Hettinger13936692007-04-11 18:40:58 +00004882- Request #1191699: Slices can now be pickled.
4883
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004884- Request #1193128: str.translate() now allows a None argument for

4886 remaining characters.
4887
Georg Brandl5cb76c12007-03-21 09:00:39 +00004888- Patch #1682205: a TypeError while unpacking an iterable is no longer

4892
Guido van Rossum143b5642007-03-23 04:58:42 +00004893- Bug #1683368: The object.__init__() and object.__new__() methods are
4894 now stricter in rejecting excess arguments. The only time when
4895 either allows excess arguments is when it is not overridden and the
4896 other one is. For backwards compatibility, when both are
4897 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004898 warning later). Also, type.__init__() insists on the same signature
4899 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004900
Georg Brandl3ee81df2008-05-17 18:14:43 +00004901- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4902 object to complex using its __complex__() method before falling back
4903 to the __float__() method. Therefore, the functions in the cmath
4904 module now can operate on objects that define a __complex__()
4905 method.

4922
Georg Brandl7b9c5552007-03-12 14:30:05 +00004923- Bug #1678647: write a newline after printing an exception in any
4924 case, even when converting the value to a string failed.
4925
Georg Brandl871f1bc2007-03-12 13:17:36 +00004926- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004927 its argument, if it exists. If not, it will work like before. This
4928 allows customizing the output of dir() in the presence of a
4929 __getattr__().

4938 parthensized forms. This means complex(repr(x)) now works instead of
4939 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00004940
Georg Brandlaa2321b2007-03-07 00:40:28 +00004941- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004942 makes the filenames the warning module prints much more sensible
4943 when a PYTHONSTARTUP file is used.

4957 sq_ass_slice instead of the sq_slice slot.
4958
Georg Brandl3ee81df2008-05-17 18:14:43 +00004959- When printing an unraisable error, don't print exceptions. before

Georg Brandl3ee81df2008-05-17 18:14:43 +00005494 AttributeError instead of an IOError when the server's response

Georg Brandl3ee81df2008-05-17 18:14:43 +00005512- Patch #1530482: add pydoc.render_doc() which returns the

5527
Georg Brandl92a6bae2007-03-13 17:43:32 +00005528- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00005529 are set for invalid interpolation sequences that would lead to
5530 errors on reading back those values.

5584
Georg Brandl3ee81df2008-05-17 18:14:43 +00005585- unittest now verifies more of its assumptions. In particular,
5586 TestCase and TestSuite subclasses (not instances) are no longer
5587 accepted in TestSuite.addTest(). This should cause no
5588 incompatibility since it never made sense with ordinary subclasses
5589 -- the failure just occurred later, with a more cumbersome
5590 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005877 that the SMTP.starttls() caller no longer needs to call ehlo()

Georg Brandl3ee81df2008-05-17 18:14:43 +00005979 time so that opening a database previously created with the DB_DUP
5980 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5981 opens. Specifically: dictionary assignment to a DB object will
5982 replace all values for a given key when the database allows
5983 duplicate values. DB users should use DB.put(k, v) when they want
5984 to store duplicates; not DB[k] = v.

Christian Heimes5b970ad2008-02-06 13:33:44 +00006323
Georg Brandl3ee81df2008-05-17 18:14:43 +00006324- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
6325 to ``PyTuple_SetItem``, it can be used to populate a brand new

6338
Georg Brandl3ee81df2008-05-17 18:14:43 +00006339- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
6340 of w# format code incorrectly truncated the length to an int, even
6341 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
6342 incorrect results with huge strings.

6366 outside of pystate.c and should not be necessary.
6367
Georg Brandl3ee81df2008-05-17 18:14:43 +00006368- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
6369 absolute imports. In earlier versions they might have used relative
6370 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00006371
Georg Brandl3ee81df2008-05-17 18:14:43 +00006372- Added case insensitive comparison methods ``PyOS_stricmp(char*,
6373 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00006374
Georg Brandl3ee81df2008-05-17 18:14:43 +00006375- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
