144 rejected; (2) parsing of strings representing infinities and nans
145 was locale aware; and (3) the interpretation of fromhex('-nan')
146 didn't match that of float('-nan').
147
Eric Smitha985a3a2009-05-05 18:26:08 +0000148- Issue #5920: For float.__format__, change the behavior with the
149 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
150 to be like 'g' but with at least one decimal point and with a
151 default precision of 12. Previously, the behavior the same but with
152 a default precision of 6. This more closely matches str(), and
153 reduces surprises when adding alignment flags to the empty
154 presentation type. This also affects the new complex.__format__ in
155 the same way.
156
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000157- Issue #5890: in subclasses of 'property' the __doc__ attribute was

Mark Dickinson95bc9802009-04-24 12:46:53 +0000181- Issue #5816: complex(repr(z)) now recovers z exactly, even when
182 z involves nans, infs or negative zeros.
183
Eric Smithaca19e62009-04-22 13:29:05 +0000184- Implement PEP 378, Format Specifier for Thousands Separator, for
185 floats, ints, and longs.
186
187- Issue #5515: 'n' formatting for ints, longs, and floats handles
188 leading zero formatting poorly.
189
190- Issue #5772: For float.__format__, don't add a trailing ".0" if
191 we're using no type code and we have an exponent.

198
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000199- Issue #1869: fix a couple of minor round() issues. round(5e15+1)
Eric Smith9139cc62009-04-30 00:58:58 +0000200 was giving 5e15+2; round(-0.0) was losing the sign of the zero.
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000201
Benjamin Peterson99d36f12009-04-15 21:26:36 +0000202- Issue #5759: float() didn't call __float__ on str subclasses.

220 untrackable objects are not tracked by the garbage collector. This can
221 reduce the size of collections and therefore the garbage collection overhead
222 on long-running programs, depending on their particular use of datatypes.
223
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000224- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

229 2**15 for the internal representation of integers, for performance
230 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
231 --enable-big-digits option to configure, which overrides the
232 default. Add sys.long_info structseq to provide information about
233 the internal format.
234

244
Brett Cannon6c4cff02009-03-11 04:51:06 +0000245- Issue #3652: Make the 'line' argument for warnings.showwarning() a
246 requirement. Means the DeprecationWarning from Python 2.6 can go away.

256 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
257 on a 64-bit system.
258
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000259- Issue #5186: Reduce hash collisions for objects with no __hash__ method by

266
Georg Brandl29c6a282009-04-05 20:23:13 +0000267- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000268 were suppressing all exceptions. These include list(), filter(), map(),
269 zip(), and bytearray().
270

299 an existing .py counterpart, override the co_filename attributes of all
300 code objects if the original filename is obsolete (which can happen if the
301 file has been renamed, moved, or if it is accessed through different paths).

307 file with `str' filename on Windows.
308
Antoine Pitrouaa687902009-01-01 14:11:22 +0000309- Issue #3680: Reference cycles created through a dict, set or deque iterator

314
Benjamin Peterson7af65562008-12-29 17:56:58 +0000315- Issue #4764: With io.open, IOError.filename is set when trying to open a
316 directory on POSIX systems.
317
Benjamin Petersonfe231b02008-12-29 17:47:42 +0000318- Issue #4764: IOError.filename is set when trying to open a directory on POSIX

Georg Brandl6425a2f2008-12-28 11:54:53 +0000321- Issue #4759: None is now allowed as the first argument of
322 bytearray.translate(). It was always allowed for bytes.translate().
323
Skip Montanarof205c132008-12-23 03:30:15 +0000324- Added test case to ensure attempts to read from a file opened for writing
325 fail.
326
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000327- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

340 exceptions.
341
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000342- Issue #4445: Replace "sizeof(PyStringObject)" with
343 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
344 str instances. On a typical machine this saves 3 bytes of memory
345 (on average) per string allocation.
346
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000347- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
348 interpreter to abort ("Fatal Python error: Could not reset the stack!")
349 instead of throwing a MemoryError.
350
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000351- Issue #3689: The list reversed iterator now supports __length_hint__

355 module couldn't be imported and \N escapes were present.
356
Vinay Sajip213faca2008-12-03 23:22:58 +0000357- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000358 method on file objects with closefd=False. The file descriptor is still
359 kept open but the file object behaves like a closed file. The ``FileIO``
360 object also got a new readonly attribute ``closefd``.
361
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000362- Issue #4348: Some bytearray methods returned that didn't cause any change to

373
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000374- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
375 method does not return iterators for the 4th and 5th items.
376
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000377- Issue #4209: Enabling unicode_literals and the print_function in the same
378 __future__ import didn't work.
379
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000380- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000381 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000382
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000383- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
384 returned a path longer than MAX_PATH. (But It's doubtful this code path is
385 really executed because I cannot move to such directory on win2k)
386
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000387- Issue #4069: When set.remove(element) is used with a set element, the element
388 is temporarily replaced with an equivalent frozenset. But the eventual
389 KeyError would always report the empty frozenset([]) as the missing key. Now
390 it correctly refers to the initial element.
391
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000392- Issue #4509: Various issues surrounding resize of bytearray objects to

Gregory P. Smith2b3eb372009-04-05 23:48:26 +0000407- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
408 returned them on 64bit platforms.
409
Walter Dörwalded960ac2009-05-03 22:36:33 +0000410- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
411 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
412 step. This avoids problems with counting UTF-8 bytes that ignores the effect
413 of using the replace error handler in PyUnicode_DecodeUTF8().
414
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000415- Issue #3739: The unicode-internal encoder now reports the number of characters
416 consumed like any other encoder (instead of the number of bytes).

1517 it easy to import both normal and optimised versions of modules.
1518 test_heapq and test_warnings have been adjusted to use it, tests for
1519 other modules with both C and Python implementations in the stdlib
1520 can be adjusted to use it over time.

1627
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001628- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1629 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1630 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1631 ``printf`` function, whereas PyString_FromFormat has an independent
1632 implementation and uses "%zd" on all platforms for size_t values.
1633 This makes a difference on win64, where ``printf`` needs "%Id" to display

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001651 was correctly parsed but parsing of subsequent arguments failed.

Antoine Pitrou0668c622008-08-26 22:42:08 +00001654 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1655 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1656 when given a tuple of classes as second argument, were looking up
1657 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1658 type object.

1729 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1730 for catch_warnings() also led to an improvement in the raising of a
1731 DeprecationWarning related to warnings.warn_explicit().

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001797What's New in Python 2.6 beta 3?
1798================================
1799
Barry Warsaw07a4a382008-08-21 01:15:08 +00001800*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001801
1802Core and Builtins
1803-----------------
1804
Guido van Rossumf8402962008-08-20 15:01:50 +00001805- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1806 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1807 extensions do not automatically benefit from the class attribute
1808 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1809 to their tp_flags field if they care. This is a backwards
1810 compatibility feature; in 3.0, all types will use the cache by
1811 default.
1812
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001813- Keyword arguments can now follow starred arguments. (``f(a, *args,
1814 keyword=23)`` is now valid syntax.)
1815
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001816- ctypes function pointers that are COM methods have a boolean True
1817 value again.
1818
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001819- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1820 by denying s# to parse objects that have a releasebuffer procedure,
1821 and introducing s*.
1822
Georg Brandl1e13ea92008-08-11 09:07:59 +00001823- Issue #3537: Fix an assertion failure when an empty but presized dict
1824 object was stored in the freelist.
1825
Mark Dickinsonb6467572008-08-04 21:30:09 +00001826- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1827 ValueError consistently across platforms.
1828
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001829- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1830 (64bit Unix, for example), unichr() would truncate its argument and return
1831 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1832
Neal Norwitze7d8be82008-07-31 17:17:14 +00001833- Apply security patches from Apple.
1834
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001835- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1836 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1837
Antoine Pitrou92f82162008-07-25 22:22:08 +00001838- Issue #1819: function calls with several named parameters are now on
1839 average 35% faster (as measured by pybench).
1840
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001841- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1842 the python debugger steps into a class statement: the free variables (local
1843 variables defined in an outer scope) would be deleted from the outer scope.
1844
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001845- Issue #2620: Overflow checking when allocating or reallocating memory
1846 was not always being done properly in some python types and extension
1847 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1848 all been updated to perform better checks and places in the code that
1849 would previously leak memory on the error path when such an allocation
1850 failed have been fixed.
1851
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001852Library
1853-------
1854
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001855- Issue #3612: Added some missing basic types in ctypes.wintypes.
1856
Benjamin Petersone977ad42008-08-20 01:42:01 +00001857- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1858 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1859
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001860- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1861 version reported by these tools does not necessarily follow the python
1862 version numbering scheme, so the module is less strict when parsing it.
1863
Nick Coghlanf70385a2008-08-18 12:42:46 +00001864- Issue #2235: Added Py3k warnings for types which will become unhashable
1865 under the stricter __hash__ inheritance rules in 3.0. Several types
1866 which did not meet the rules for hash invariants and were already
1867 unhashable in 3.0 have now been explicitly flagged as unhashable in
1868 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1869 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1870
Brett Cannon88f801d2008-08-18 00:46:22 +00001871- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

1879
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001880- Issue #3575: Incremental decoder's decode function now takes bytearray
1881 by using 's*' instead of 't#'.
1882
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00001883- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001884 fails unicode conversion on 2nd parameter. (windows only)
1885
Facundo Batista94f243a2008-08-17 03:38:39 +00001886- Issue 2464. urllib2 now supports a malformation in the URL received
1887 in a redirect.
1888
Brett Cannonabe423e2008-08-16 21:47:07 +00001889- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001890 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001891
Facundo Batistaeb90b782008-08-16 14:44:07 +00001892- Issue #2776: fixed small issue when handling an URL with double slash
1893 after a 302 response in the case of not going through a proxy.
1894
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001895- Issue #2676: in the email package, content-type parsing was hanging on
1896 pathological input because of quadratic or exponential behaviour of a
1897 regular expression.
1898
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001899- Issue #3476: binary buffered reading through the new "io" library is now
1900 thread-safe.
1901
Brett Cannonbf3157b2008-08-14 05:00:03 +00001902- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1903 since mimetools itself is deprecated. Because modules are cached, all
1904 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1905
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001906- Issue #3134: shutil referenced undefined WindowsError symbol.
1907
Robert Schuppenies14646332008-08-10 11:01:53 +00001908- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1909 menu entries were not deleted.
1910
Brett Cannon83e81842008-08-09 23:30:55 +00001911- Copied the implementation of reduce() to _functools.reduce() to have a
1912 version that did not raise a DeprecationWarning under -3.
1913
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001914- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1915 a MemoryError rather than silently stop the iteration.
1916
Guido van Rossum59ce9012008-08-09 14:55:34 +00001917- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1918 to _sre.compile() will now be rejected. This should not affect anybody
1919 since the re.compile() function never generates invalid re-bytecode.
1920
Skip Montanaroa032bf42008-08-08 22:52:51 +00001921- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that

1926 the reload() built-in has been removed.
1927
Brett Cannon7e30b672008-08-04 21:52:25 +00001928- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001929 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00001940 asking for a specific length. This problem only affected files opened
1941 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001942

1967 file name rather than a ZipInfo instance, so files are extracted with
1968 mode 0600 rather than 000 under Unix.
1969
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001970- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

1987 regarding lack of coverage of new-style classes have also been
1988 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001996Core and Builtins
1997-----------------
1998
Georg Brandl3e483f62008-07-16 22:57:41 +00001999- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2000 its methods now allow for items objects that can be converted to
2001 an integer using operator.index().
2002
Mark Dickinson64b7e502008-07-16 09:40:03 +00002003- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2004 produced a ValueError instead of giving the correct float.
2005
Eric Smitha5fa5a22008-07-16 00:11:49 +00002006- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2007 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2008
Mark Dickinson7103aa42008-07-15 19:08:33 +00002009- Issue #3008: the float type has a new instance method 'float.hex'
2010 and a new class method 'float.fromhex' to convert floating-point
2011 numbers to and from hexadecimal strings, respectively.
2012
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002013- Issue #2235: __hash__ is once again inherited by default. To allow
2014 collections.Hashable to remain meaningful in the presence of the
2015 default hash implementation (object.__hash__), it is now possible
2016 to explicit block inheritance of hash by setting __hash__=None at
2017 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2018 level.
2019
Nick Coghlanb028f502008-07-13 14:52:36 +00002020- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2021 the parent module cannot be found while performing an absolute import.
2022 This means that an incorrectly defined __package__ attribute will
2023 now only prevent relative imports in that module rather than causing
2024 all imports from that module to fail.
2025
Nick Coghlan14ff9942008-07-08 14:21:42 +00002026- Issue #2517: Allow unicode messages in Exceptions again by correctly
2027 bypassing the instance dictionary when looking up __unicode__ on
2028 new-style classes.
2029
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002030- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2031 set to a custom object whose write() method happens to install
2032 another file in sys.stdout.
2033
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002034- Issue #3088: Corrected a race condition in classes derived from
2035 threading.local: the first member set by a thread could be saved in
2036 another thread's dictionary.
2037
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002038- Issue #3004: Minor change to slice.indices(): the start and stop
2039 arguments are now treated identically, making the behaviour easier
2040 to describe and understand. For example, slice(None, -10,
2041 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2042 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2043 10, -1).
2044
Georg Brandl278fc502008-07-19 12:46:12 +00002045- Issue #3219: Calling a function with repeated keyword arguments,
2046 f(a=2, a=23), would not cause a syntax error. This was a regression
2047 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002048
Georg Brandl278fc502008-07-19 12:46:12 +00002049- Issue #2862: Make int and float freelist management consistent with
2050 other freelists. Changes their CompactFreeList apis into
2051 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00002052

2054-------
2055
Thomas Heller57adf222008-08-14 19:10:48 +00002056- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2057 api functions without holding the GIL, which could lead to a fatal
2058 error when they failed.
2059
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002060- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00002068- Issue #3125: Remove copy_reg in multiprocessing and replace it with
2069 ForkingPickler.register() to resolve conflict with ctypes.
2070
Vinay Sajip51e65192008-07-18 09:01:10 +00002071- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00002072
Thomas Heller880f5292008-07-15 19:39:38 +00002073- Issue #3313: Fixed a crash when a failed dlopen() call does not set
2074 a valid dlerror() message.
2075
Thomas Heller2bad6572008-07-15 17:19:50 +00002076- Issue #3258: Fixed a crash when a ctypes POINTER type to an
2077 incomplete structure was created.

2082
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002083- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00002084
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002085- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2086 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002087 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002088 content-length. The problem had been corrected in the 2.4 branch, but never
2089 merged into trunk.
2090
Georg Brandle78fbcc2008-07-05 10:13:36 +00002091- Issue #2663: add filtering capability to shutil.copytree().

Vinay Sajip51e65192008-07-18 09:01:10 +00002099 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00002100

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002102 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00002103
Nick Coghlanc060b0e2008-07-02 13:09:19 +00002104- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
2105 handling is now the same as that of other special attributes like __name__).
2106
Brett Cannon8bb8fa52008-07-02 01:57:08 +00002107- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Georg Brandl3ee81df2008-05-17 18:14:43 +00002559- Issue #1631171: Re-implement the 'warnings' module in C (the
2560 original Python code has been kept as backup). This will allow for
2561 using the 'warning's machinery in such places as the parser where
2562 use of pure Python code is not possible. Both the ``showarning()``
2563 and ``formatwarning()`` gain an optional 'line' argument which is
2564 not called by default for backwards-compatibility reasons. Setting
2565 ``warnings.showwarning()`` to an implementation that lacks support
2566 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002629- Issue #2550: The approach used by client/server code for obtaining
2630 ports to listen on in network-oriented tests has been refined in an
2631 effort to facilitate running multiple instances of the entire
2632 regression test suite in parallel without issue.
2633 test_support.bind_port() has been fixed such that it will always
2634 return a unique port -- which wasn't always the case with the
2635 previous implementation, especially if socket options had been set
2636 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2637 new implementation of bind_port() will actually raise an exception
2638 if it is passed an AF_INET/SOCK_STREAM socket with either the
2639 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2640 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2641 the socket it's been passed. This currently only applies to
2642 Windows. This option prevents any other sockets from binding to the
2643 host/port we've bound to, thus removing the possibility of the
2644 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2645 when a second SOCK_STREAM socket binds and accepts to a host/port
2646 that's already been bound by another socket. The optional preferred
2647 port parameter to bind_port() has been removed. Under no
2648 circumstances should tests be hard coding ports!
2649
2650 test_support.find_unused_port() has also been introduced, which will
2651 pass a temporary socket object to bind_port() in order to obtain an
2652 unused port. The temporary socket object is then closed and
2653 deleted, and the port is returned. This method should only be used
2654 for obtaining an unused port in order to pass to an external program
2655 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2656 a parameter to a server-oriented class that doesn't give you direct
2657 access to the underlying socket used.
2658
2659 Finally, test_support.HOST has been introduced, which should be used
2660 for the host argument of any relevant socket calls (i.e. bind and
2661 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002662
2663 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002664 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002665 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2666 test_asynchat and test_socket_ssl.
2667
Georg Brandl3ee81df2008-05-17 18:14:43 +00002668 It is now possible for multiple instances of the regression test
2669 suite to run in parallel without issue.

2825 processor information on Windows XP and later. As a result,
Marc-André Lemburga1867752008-03-20 18:08:00 +00002826 platform.machine() and platform.processor() will report this
2827 information as well.

2936-----------------
2937
Fred Drakea8ee94b2008-03-01 02:45:07 +00002938- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002939 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00002941- Issue #2067: file.__exit__() now calls subclasses' close() method.
2942
2943- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002944
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002945- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002946 issue 215555 for a discussion.
2947
Eric Smitha73fbe72008-02-23 03:09:44 +00002948- Added the future_builtins module, which contains hex() and oct().
2949 These are the PEP 3127 version of these functions, designed to be
2950 compatible with the hex() and oct() builtins from Python 3.0. They
2951 differ slightly in their output formats from the existing, unchanged
2952 Python 2.6 builtins. The expected usage of the future_builtins
2953 module is:
2954 from future_builtins import hex, oct
2955
Eric Smith7ef40bf2008-02-20 23:34:22 +00002956- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2957 exponents for exponents with absolute value < 100. Follows C99
2958 standard. This is a change on Windows, which would use 3 digits.
2959 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2960 so that any alterations it does to the resulting string will be
2961 available in stringlib/formatter.h (for float.__format__).
2962
Eric Smith5a3c1352008-02-19 13:21:56 +00002963- Implemented PEP 3101, Advanced String Formatting. This adds a new
2964 builtin format(); a format() method for str and unicode; a
2965 __format__() method to object, str, unicode, int, long, float, and
2966 datetime; the class string.Formatter; and the C API
2967 PyObject_Format().
2968
Georg Brandl3ee81df2008-05-17 18:14:43 +00002969- Fixed several potential crashes, all caused by specially crafted
2970 __del__ methods exploiting objects in temporarily inconsistent
2971 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002972
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002973- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002974 prevent a possible crash: an Abstract Base Class would try to access
2975 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002976

Georg Brandl3ee81df2008-05-17 18:14:43 +00002980- Clear all free lists during a gc.collect() of the highest generation
2981 in order to allow pymalloc to free more arenas. Python may give back
2982 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002983
Georg Brandl3ee81df2008-05-17 18:14:43 +00002984- Issue #2045: Fix an infinite recursion triggered when printing a
2985 subclass of collections.defaultdict, if its default_factory is set
2986 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002987
Christian Heimesf75dbef2008-02-08 00:11:31 +00002988- Fixed a minor memory leak in dictobject.c. The content of the free
2989 list was not freed on interpreter shutdown.
2990
Georg Brandl3ee81df2008-05-17 18:14:43 +00002991- Limit free list of method and builtin function objects to 256
2992 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002993
Georg Brandl3ee81df2008-05-17 18:14:43 +00002994- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2995 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002996 to compact the internal free lists of pre-allocted ints and floats.
2997
Georg Brandl3ee81df2008-05-17 18:14:43 +00002998- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2999 calls. Python expected the return type int but the fork familie
3000 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003001
Georg Brandl3ee81df2008-05-17 18:14:43 +00003002- Issue #1678380: Fix a bug that identifies 0j and -0j when they

3012 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003013
Georg Brandl3ee81df2008-05-17 18:14:43 +00003014- Patch #1473257: generator objects gain a gi_code attribute. This is
3015 the same object as the func_code attribute of the function that
3016 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003017
Georg Brandl3ee81df2008-05-17 18:14:43 +00003018- Issue #1920: "while 0" statements were completely removed by the
3019 compiler, even in the presence of an "else" clause, which is
3020 supposed to be run when the condition is false. Now the compiler
3021 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003022
Guido van Rossumeead05f2008-01-24 18:21:02 +00003023- A few crashers fixed: weakref_in_del.py (issue #1377858);
3024 loosing_dict_ref.py (issue #1303614, test67.py);
3025 borrowed_ref_[34].py (not in tracker).
3026
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003027- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003028 suppressed while an extension is loaded by calling SetErrorMode in

3030
Georg Brandl3ee81df2008-05-17 18:14:43 +00003031- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003032 several extension methods and modules do not work without unicode
3033 support.
3034
Georg Brandl26543b12008-01-21 18:36:51 +00003035- Issue #1882: when compiling code from a string, encoding cookies in the
3036 second line of code were not always recognized correctly.
3037

3039
Georg Brandl6caad7d2008-01-26 14:19:22 +00003040- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003041 added.
3042
Christian Heimesc94e2b52008-01-14 04:13:37 +00003043- sys.float_info / PyFloat_GetInfo: The floating point information
3044 object was converted from a dict to a specialized structseq object.
3045
Georg Brandl3ee81df2008-05-17 18:14:43 +00003046- Patch #1816: Added sys.flags structseq. It exposes the status of
3047 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003048
Georg Brandl3ee81df2008-05-17 18:14:43 +00003049- Objects/structseq.c: Implemented new structseq representation. The

3062 envvar and sys.dont_write_bytecode attribute. All these can be set
3063 to forbid Python to attempt to write compiled bytecode files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003065- Improve some exception messages when Windows fails to load an
3066 extension module. Now we get for example '%1 is not a valid Win32
3067 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003068

Christian Heimes0a8143f2007-12-18 23:22:54 +00003074- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003075 and INF. float("nan"), float("inf") and float("-inf") now work on
3076 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003077
Georg Brandl3ee81df2008-05-17 18:14:43 +00003078- Compiler now generates simpler and faster code for dictionary
3079 literals. The oparg for BUILD_MAP now indicates an estimated
3080 dictionary size. There is a new opcode, STORE_MAP, for adding
3081 entries to the dictionary.

3099 running, and if the deallocation of its frames somehow calls the
3100 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00003101

Georg Brandl3ee81df2008-05-17 18:14:43 +00003110- Patch #1739468: Directories and zipfiles containing a __main__.py
3111 file can now be directly executed by passing their name to the
3112 interpreter. The directory/zipfile is automatically inserted as the
3113 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003114
Georg Brandl3ee81df2008-05-17 18:14:43 +00003115- Issue #1265: Fix a problem with sys.settrace, if the tracing
3116 function uses a generator expression when at the same time the
3117 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003118
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003119- sets and frozensets now have an isdisjoint() method.

3122
Neal Norwitz44f326e2007-10-05 05:29:17 +00003123- Fix warnings found by the new version of the Coverity checker.
3124
Georg Brandl3ee81df2008-05-17 18:14:43 +00003125- The enumerate() builtin function is no longer bounded to sequences
3126 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3127 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003128
Georg Brandl3ee81df2008-05-17 18:14:43 +00003129- Issue #1686386: Tuple's tp_repr did not take into account the
3130 possibility of having a self-referential tuple, which is possible
3131 from C code. Nor did object's tp_str consider that a type's tp_str
3132 could do something that could lead to an inifinite recursion.
3133 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3134 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003135
Georg Brandl3ee81df2008-05-17 18:14:43 +00003136- Issue #1164: It was possible to trigger deadlock when using the
3137 'print' statement to write to a file since the GIL was not released
3138 as needed. Now PyObject_Print() does the right thing along with
3139 various tp_print implementations of the built-in types and those in
3140 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003141
Georg Brandl3ee81df2008-05-17 18:14:43 +00003142- Issue #1147: Exceptions were directly allowing string exceptions in
3143 their throw() method even though string exceptions no longer
3144 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003145
Georg Brandl3ee81df2008-05-17 18:14:43 +00003146- Issue #1096: Prevent a segfault from getting the repr of a very
3147 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003148
Brett Cannon1e534b52007-09-07 04:18:30 +00003149- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003150 PyObject_Call() never calling back out to Python code to trigger
3151 recursion depth updates/checks. Required the creation of a static
3152 RuntimeError instance in case normalizing an exception put the
3153 recursion check value past its limit. Fixes crashers
3154 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003155
Georg Brandl3ee81df2008-05-17 18:14:43 +00003156- Patch #1031213: Decode source line in SyntaxErrors back to its

3160 with %G.
3161
Georg Brandl3ee81df2008-05-17 18:14:43 +00003162- Prevent expandtabs() on string and unicode objects from causing a

Neal Norwitz0ac60192007-05-27 04:08:54 +00003169- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003170 __*__ attributes. (Some already existed, e.g., __doc__ and
3171 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003172
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003173- Add -3 option to the interpreter to warn about features that are
3174 deprecated and will be changed/removed in Python 3.0.
3175
Georg Brandl2134e752007-05-21 20:34:16 +00003176- Patch #1686487: you can now pass any mapping after '**' in function
3177 calls.
3178
Collin Winter62903052007-05-18 23:11:24 +00003179- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003180 "except E as target:". This is to provide forwards compatibility
3181 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003182
Brett Cannon229cee22007-05-05 01:34:02 +00003183- Deprecate BaseException.message as per PEP 352.
3184
Georg Brandl3ee81df2008-05-17 18:14:43 +00003185- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00003186 inherited from a builtin base.
3187
Vinay Sajip8549ce32007-05-06 17:53:37 +00003188- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003189 setting a plain string, ie don't expand to single letter identifiers.
3190
Raymond Hettinger13936692007-04-11 18:40:58 +00003191- Request #1191699: Slices can now be pickled.
3192
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003193- Request #1193128: str.translate() now allows a None argument for
3194 translations that only remove characters without re-mapping the
3195 remaining characters.
3196
Georg Brandl5cb76c12007-03-21 09:00:39 +00003197- Patch #1682205: a TypeError while unpacking an iterable is no longer
3198 masked by a generic one with the message "unpack non-sequence".
3199
Neal Norwitzaa754b72007-03-21 06:39:48 +00003200- Remove unused file Python/fmod.c.
3201
Guido van Rossum143b5642007-03-23 04:58:42 +00003202- Bug #1683368: The object.__init__() and object.__new__() methods are
3203 now stricter in rejecting excess arguments. The only time when
3204 either allows excess arguments is when it is not overridden and the
3205 other one is. For backwards compatibility, when both are
3206 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003207 warning later). Also, type.__init__() insists on the same signature
3208 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003209
Georg Brandl3ee81df2008-05-17 18:14:43 +00003210- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3211 object to complex using its __complex__() method before falling back
3212 to the __float__() method. Therefore, the functions in the cmath
3213 module now can operate on objects that define a __complex__()
3214 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003215
Georg Brandl3ee81df2008-05-17 18:14:43 +00003216- Patch #1623563: allow __class__ assignment for classes with
3217 __slots__. The old and the new class are still required to have the
3218 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00003219
Georg Brandl3ee81df2008-05-17 18:14:43 +00003220- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00003223- Patch #1462488: Python no longer segfaults when
3224 ``object.__reduce_ex__()`` is called with an object that is faking
3225 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003226
Georg Brandl3ee81df2008-05-17 18:14:43 +00003227- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00003230- Patch #1444529: the builtin compile() now accepts keyword arguments.
3231
Georg Brandl7b9c5552007-03-12 14:30:05 +00003232- Bug #1678647: write a newline after printing an exception in any
3233 case, even when converting the value to a string failed.
3234
Georg Brandl871f1bc2007-03-12 13:17:36 +00003235- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003236 its argument, if it exists. If not, it will work like before. This
3237 allows customizing the output of dir() in the presence of a
3238 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003239
Collin Winter276887b2007-03-12 16:11:39 +00003240- Patch #922167: Python no longer segfaults when faced with infinitely
3241 self-recursive reload() calls (as reported by bug #742342).
3242
Georg Brandl3ee81df2008-05-17 18:14:43 +00003243- Patch #1675981: remove unreachable code from ``type.__new__()``
3244 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003246- Patch #1491866: change the complex() constructor to allow
3247 parthensized forms. This means complex(repr(x)) now works instead of
3248 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003249
Georg Brandlaa2321b2007-03-07 00:40:28 +00003250- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003251 makes the filenames the warning module prints much more sensible
3252 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003253
Georg Brandl49aafc92007-03-07 00:34:46 +00003254- Variant of patch #697613: don't exit the interpreter on a SystemExit
3255 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003256 variable is given, but break into the interactive interpreter just
3257 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00003265- Patch #1674228: when assigning a slice (old-style), check for the
3266 sq_ass_slice instead of the sq_slice slot.
3267
Georg Brandl3ee81df2008-05-17 18:14:43 +00003268- When printing an unraisable error, don't print exceptions. before
3269 the name. This duplicates the behavior whening normally printing
3270 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00003271
Georg Brandl3ee81df2008-05-17 18:14:43 +00003272- Bug #1653736: Properly discard third argument to

Georg Brandl3ee81df2008-05-17 18:14:43 +00003803 AttributeError instead of an IOError when the server's response
3804 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00003805

3820
Georg Brandl3ee81df2008-05-17 18:14:43 +00003821- Patch #1530482: add pydoc.render_doc() which returns the

3836
Georg Brandl92a6bae2007-03-13 17:43:32 +00003837- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003838 are set for invalid interpolation sequences that would lead to
3839 errors on reading back those values.

3893
Georg Brandl3ee81df2008-05-17 18:14:43 +00003894- unittest now verifies more of its assumptions. In particular,
3895 TestCase and TestSuite subclasses (not instances) are no longer
3896 accepted in TestSuite.addTest(). This should cause no
3897 incompatibility since it never made sense with ordinary subclasses
3898 -- the failure just occurred later, with a more cumbersome
3899 exception.

Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004186 that the SMTP.starttls() caller no longer needs to call ehlo()

Georg Brandl3ee81df2008-05-17 18:14:43 +00004288 time so that opening a database previously created with the DB_DUP
4289 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4290 opens. Specifically: dictionary assignment to a DB object will
4291 replace all values for a given key when the database allows
4292 duplicate values. DB users should use DB.put(k, v) when they want
4293 to store duplicates; not DB[k] = v.

Christian Heimes5b970ad2008-02-06 13:33:44 +00004632
Georg Brandl3ee81df2008-05-17 18:14:43 +00004633- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4634 to ``PyTuple_SetItem``, it can be used to populate a brand new
4635 frozenset; but it does not steal a reference to the added item.

4647
Georg Brandl3ee81df2008-05-17 18:14:43 +00004648- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4649 of w# format code incorrectly truncated the length to an int, even
4650 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4651 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004652
Georg Brandl3ee81df2008-05-17 18:14:43 +00004653- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

4675 outside of pystate.c and should not be necessary.
4676
Georg Brandl3ee81df2008-05-17 18:14:43 +00004677- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4678 absolute imports. In earlier versions they might have used relative
4679 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004680
Georg Brandl3ee81df2008-05-17 18:14:43 +00004681- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4682 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004683
Georg Brandl3ee81df2008-05-17 18:14:43 +00004684- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
