Barry Warsaw12582c92008-10-02 03:33:51 +00006What's New in Python 2.7 alpha 1
7================================
8
9*Release date: XX-XXX-20XX*
10
11Core and Builtins
12-----------------
13
Ronald Oussorene0154ed2009-03-30 23:10:35 +000014- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
15 the end sys.path, for compatibility with the system install of Python.
16
Antoine Pitrouf8387af2009-03-23 18:41:45 +000017- Issue #4688: Add a heuristic so that tuples and dicts containing only
18 untrackable objects are not tracked by the garbage collector. This can
19 reduce the size of collections and therefore the garbage collection overhead
20 on long-running programs, depending on their particular use of datatypes.
21
Mark Dickinson0b666bf2009-03-23 18:25:13 +000022- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
23 improve its performance. Long divisions and remainder operations
24 are now between 50% and 150% faster.
25
Mark Dickinsonefc82f72009-03-20 15:51:55 +000026- Issue #4258: Make it possible to use base 2**30 instead of base
27 2**15 for the internal representation of integers, for performance
28 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
29 --enable-big-digits option to configure, which overrides the
30 default. Add sys.long_info structseq to provide information about
31 the internal format.
32
Benjamin Peterson6ffe8522009-03-18 20:52:15 +000033- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
34 result traceback.__members__ no longer exists.)
35
Mark Dickinson6b265f12009-03-18 16:07:26 +000036- Issue #4474: PyUnicode_FromWideChar now converts characters outside
37 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
38 and sizeof(Py_UNICODE) == 2.
39
Eric Smith6f42edb2009-03-14 11:57:26 +000040- Issue #5237: Allow auto-numbered fields in str.format(). For
41 example: '{} {}'.format(1, 2) == '1 2'.
42
Brett Cannon6c4cff02009-03-11 04:51:06 +000043- Issue #3652: Make the 'line' argument for warnings.showwarning() a
44 requirement. Means the DeprecationWarning from Python 2.6 can go away.
45
Eric Smithe9fb6862009-02-20 14:02:36 +000046- Issue #5247: Improve error message when unknown format codes are
47 used when using str.format() with str, unicode, long, int, and
48 float arguments.
49
Raymond Hettinger08259e82009-02-18 23:10:19 +000050- Running Python with the -3 option now also warns about classic division
51 for ints and longs.
52
Mark Dickinson2ffb26f2009-02-15 10:13:41 +000053- Issue #5260: Long integers now consume less memory: average
54 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
55 on a 64-bit system.
56
Antoine Pitrou76a4b892009-02-13 13:52:33 +000057- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
58 rotating the object pointer by 4 bits to the right.
59
Mark Dickinsonc97c9092009-02-09 14:18:43 +000060- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
61 it now forces its argument to double before testing for infinity.
62
Benjamin Petersone18ef192009-01-20 14:21:16 +000063- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
64
Raymond Hettingerb5163702009-02-02 21:50:13 +000065- Issue 1242657: the __len__() and __length_hint__() calls in several tools
66 were suppressing all exceptions. These include list(), filter(), map(),
67 zip(), and bytearray().
68
Benjamin Peterson596d3062009-01-19 15:42:23 +000069- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
70 functions.
71
Benjamin Peterson5848d1f2009-01-19 00:08:08 +000072- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an
73 OSError.
74
Amaury Forgeot d'Arca18392a2009-01-13 23:19:08 +000075- Issue #4807: Port the _winreg module to Windows CE.
76
Antoine Pitrouc2f02212009-01-13 23:13:52 +000077- Issue #4935: The overflow checking code in the expandtabs() method common
78 to str, bytes and bytearray could be optimized away by the compiler, letting
79 the interpreter segfault instead of raising an error.
80
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +000081- Issue #3720: Fix a crash when an iterator modifies its class and removes its
82 __next__ method.
83
Martin v. Löwise3422fa2009-01-12 08:11:24 +000084- Issue #4893: Use NT threading on CE.
85
Martin v. Löwis1b3bef22009-01-12 07:57:11 +000086- Issue #4915: Port sysmodule to Windows CE.
87
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +000088- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
89 collecting the oldest generation) so that allocating lots of objects without
90 destroying them does not show quadratic performance. Based on a proposal by
91 Martin von Löwis at
92 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
93
Martin v. Löwisb90304a2009-01-07 18:40:40 +000094- Issue #4850: Change COUNT_ALLOCS variables to Py_ssize_t.
95
Antoine Pitroue96d4ea2009-01-06 18:10:47 +000096- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
97 an existing .py counterpart, override the co_filename attributes of all
98 code objects if the original filename is obsolete (which can happen if the
99 file has been renamed, moved, or if it is accessed through different paths).
100 Patch by Ziga Seilnacht and Jean-Paul Calderone.
101
Martin v. Löwis5344c992009-01-02 20:32:55 +0000102- Issue #4075: Use OutputDebugStringW in Py_FatalError.
103
Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +0000104- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
105 file with `str' filename on Windows.
106
Antoine Pitrouaa687902009-01-01 14:11:22 +0000107- Issue #3680: Reference cycles created through a dict, set or deque iterator
108 did not get collected.
109
Nick Coghlan180e4002008-12-30 01:18:48 +0000110- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
111 where the tp_hash and tp_dict slots are both NULL.
112
Benjamin Peterson7af65562008-12-29 17:56:58 +0000113- Issue #4764: With io.open, IOError.filename is set when trying to open a
114 directory on POSIX systems.
115
Benjamin Petersonfe231b02008-12-29 17:47:42 +0000116- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
117 systems.
118
Georg Brandl6425a2f2008-12-28 11:54:53 +0000119- Issue #4759: None is now allowed as the first argument of
120 bytearray.translate(). It was always allowed for bytes.translate().
121
Skip Montanarof205c132008-12-23 03:30:15 +0000122- Added test case to ensure attempts to read from a file opened for writing
123 fail.
124
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000125- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
126 print elapsed times, not only when some objects are uncollectable /
127 unreachable. Original patch by Neil Schemenauer.
128
Mark Dickinson1a707982008-12-17 16:14:37 +0000129- Issue #3439: Add a bit_length method to int and long.
130
Antoine Pitroud0c35152008-12-17 00:38:28 +0000131- Issue #2183: Simplify and optimize bytecode for list comprehensions.
132 Original patch by Neal Norwitz.
133
Amaury Forgeot d'Arcad9b5992008-12-10 23:22:49 +0000134- Issue #4597: Fixed exception handling when the __exit__ function of a
135 context manager returns a value that cannot be converted to a bool.
136
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000137- Issue #4597: Fixed several opcodes that weren't always propagating
138 exceptions.
139
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000140- Issue #4445: Replace "sizeof(PyStringObject)" with
141 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
142 str instances. On a typical machine this saves 3 bytes of memory
143 (on average) per string allocation.
144
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000145- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
146 interpreter to abort ("Fatal Python error: Could not reset the stack!")

148
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000149- Issue #3689: The list reversed iterator now supports __length_hint__

154
Vinay Sajip213faca2008-12-03 23:22:58 +0000155- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000156 method on file objects with closefd=False. The file descriptor is still
157 kept open but the file object behaves like a closed file. The ``FileIO``
158 object also got a new readonly attribute ``closefd``.
159
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000160- Issue #4348: Some bytearray methods returned that didn't cause any change to
161 the bytearray, returned the same bytearray instead of a copy.
162
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000163- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
164
Benjamin Peterson273c2332008-11-17 22:39:09 +0000165- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
166
Benjamin Peterson6624a9f2008-11-03 15:14:51 +0000167- Issue #4048: The parser module now correctly validates relative imports.
168
Benjamin Petersondcee09d2008-10-31 02:16:05 +0000169- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
170 exec statement.
171
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000172- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
173 method does not return iterators for the 4th and 5th items.
174
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000175- Issue #4209: Enabling unicode_literals and the print_function in the same
176 __future__ import didn't work.
177
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000178- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000179 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000180
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000181- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
182 returned a path longer than MAX_PATH. (But It's doubtful this code path is
183 really executed because I cannot move to such directory on win2k)
184
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000185- Issue #4069: When set.remove(element) is used with a set element, the element
186 is temporarily replaced with an equivalent frozenset. But the eventual
187 KeyError would always report the empty frozenset([]) as the missing key. Now
188 it correctly refers to the initial element.
189
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000190- Issue #4509: Various issues surrounding resize of bytearray objects to
191 which there are buffer exports.
192
Benjamin Peterson8d5934b2008-12-27 18:24:11 +0000193- Issue #4748: Lambda generators no longer return a value.
194
Kristján Valur Jónsson6220e412009-01-12 09:20:34 +0000195- Issue #3582: Use native TLS functions on Windows
196

218
Guilherme Polo1972d162009-03-27 21:43:08 +0000219- Adjusted _tkinter to compile without warnings when WITH_THREAD is not

Gregory P. Smith28399852009-03-31 16:54:10 +0000228- The unittest.TestCase.assertRaises() method now returns a context manager when
229 not given a callable so that code to be tested can be written inline using
230 a with statement.
231
232- The unittest.TestCase.assertEqual() now displays the differences in lists,
233 tuples, dicts and sets on failure. Many new handy type and comparison
234 specific assert* methods have been added that fail with error messages
235 actually useful for debugging. Contributed in part by Google. [Issue #2578]
236
Lars Gustäbel2020a592009-03-22 20:09:33 +0000237- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop

806
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000807- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
808 PyString_FromFormat or PyErr_Format to display size_t values. The macro
809 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
810 ``printf`` function, whereas PyString_FromFormat has an independent

Antoine Pitrou0668c622008-08-26 22:42:08 +0000833 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
834 mechanism. In the process, fix a bug where isinstance() and issubclass(),

905 path to the Python binary.
906
Brett Cannon1eaf0742008-09-02 01:25:16 +0000907- Issue 3602: Moved test.test_support.catch_warning() to
908 warnings.catch_warnings() along with some API cleanup. Expanding the tests
909 for catch_warnings() also led to an improvement in the raising of a
910 DeprecationWarning related to warnings.warn_explicit().
911
Benjamin Peterson973e6c22008-09-01 23:12:58 +0000912- The deprecation warnings for the old camelCase threading API were removed.

931
Jesse Noller438195f2009-01-18 21:04:36 +0000932- Issue #4301: Patch the logging module to add processName support, remove
933 _check_logger_class from multiprocessing.
934
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +0000935- Issue #2975: When compiling several extension modules with Visual Studio 2008
936 from the same python interpreter, some environment variables would grow
937 without limit.

Gerhard Häring6e1afcf2008-09-12 18:58:57 +0000944- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
945 remaining ones have "pysqlite_" prefix.
946
Gerhard Häringe6872eb2008-09-12 22:33:22 +0000947- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000976What's New in Python 2.6 beta 3?
977================================
978
Barry Warsaw07a4a382008-08-21 01:15:08 +0000979*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000980
981Core and Builtins
982-----------------
983
Guido van Rossumf8402962008-08-20 15:01:50 +0000984- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
985 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
986 extensions do not automatically benefit from the class attribute
987 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
988 to their tp_flags field if they care. This is a backwards
989 compatibility feature; in 3.0, all types will use the cache by
990 default.
991
Benjamin Petersonf647dc12008-08-20 01:27:30 +0000992- Keyword arguments can now follow starred arguments. (``f(a, *args,
993 keyword=23)`` is now valid syntax.)
994
Thomas Heller0ad5ae02008-08-19 19:25:04 +0000995- ctypes function pointers that are COM methods have a boolean True
996 value again.
997
Martin v. Löwisf91d46a2008-08-12 14:49:50 +0000998- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
999 by denying s# to parse objects that have a releasebuffer procedure,
1000 and introducing s*.
1001
Georg Brandl1e13ea92008-08-11 09:07:59 +00001002- Issue #3537: Fix an assertion failure when an empty but presized dict
1003 object was stored in the freelist.
1004
Mark Dickinsonb6467572008-08-04 21:30:09 +00001005- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1006 ValueError consistently across platforms.
1007
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001008- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1009 (64bit Unix, for example), unichr() would truncate its argument and return
1010 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1011
Neal Norwitze7d8be82008-07-31 17:17:14 +00001012- Apply security patches from Apple.
1013
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001014- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1015 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1016
Antoine Pitrou92f82162008-07-25 22:22:08 +00001017- Issue #1819: function calls with several named parameters are now on
1018 average 35% faster (as measured by pybench).
1019
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001020- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1021 the python debugger steps into a class statement: the free variables (local
1022 variables defined in an outer scope) would be deleted from the outer scope.
1023
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001024- Issue #2620: Overflow checking when allocating or reallocating memory
1025 was not always being done properly in some python types and extension
1026 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1027 all been updated to perform better checks and places in the code that
1028 would previously leak memory on the error path when such an allocation
1029 failed have been fixed.
1030
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001031Library
1032-------
1033
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001034- Issue #3612: Added some missing basic types in ctypes.wintypes.
1035
Benjamin Petersone977ad42008-08-20 01:42:01 +00001036- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1037 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1038
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001039- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1040 version reported by these tools does not necessarily follow the python
1041 version numbering scheme, so the module is less strict when parsing it.
1042
Nick Coghlanf70385a2008-08-18 12:42:46 +00001043- Issue #2235: Added Py3k warnings for types which will become unhashable
1044 under the stricter __hash__ inheritance rules in 3.0. Several types
1045 which did not meet the rules for hash invariants and were already
1046 unhashable in 3.0 have now been explicitly flagged as unhashable in
1047 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1048 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1049
Brett Cannon88f801d2008-08-18 00:46:22 +00001050- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1051 imported into the module but exposed as part of the module's API.
1052

1058
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001059- Issue #3575: Incremental decoder's decode function now takes bytearray
1060 by using 's*' instead of 't#'.
1061
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00001062- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001063 fails unicode conversion on 2nd parameter. (windows only)
1064
Facundo Batista94f243a2008-08-17 03:38:39 +00001065- Issue 2464. urllib2 now supports a malformation in the URL received
1066 in a redirect.
1067
Brett Cannonabe423e2008-08-16 21:47:07 +00001068- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001069 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001070
Facundo Batistaeb90b782008-08-16 14:44:07 +00001071- Issue #2776: fixed small issue when handling an URL with double slash
1072 after a 302 response in the case of not going through a proxy.
1073
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001074- Issue #2676: in the email package, content-type parsing was hanging on
1075 pathological input because of quadratic or exponential behaviour of a
1076 regular expression.
1077
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001078- Issue #3476: binary buffered reading through the new "io" library is now
1079 thread-safe.
1080
Brett Cannonbf3157b2008-08-14 05:00:03 +00001081- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1082 since mimetools itself is deprecated. Because modules are cached, all
1083 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1084
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001085- Issue #3134: shutil referenced undefined WindowsError symbol.
1086
Robert Schuppenies14646332008-08-10 11:01:53 +00001087- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1088 menu entries were not deleted.
1089
Brett Cannon83e81842008-08-09 23:30:55 +00001090- Copied the implementation of reduce() to _functools.reduce() to have a
1091 version that did not raise a DeprecationWarning under -3.
1092
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001093- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1094 a MemoryError rather than silently stop the iteration.
1095
Guido van Rossum59ce9012008-08-09 14:55:34 +00001096- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1097 to _sre.compile() will now be rejected. This should not affect anybody
1098 since the re.compile() function never generates invalid re-bytecode.
1099
Skip Montanaroa032bf42008-08-08 22:52:51 +00001100- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1101 upon first access it can be automatically initialized from the csv file if
1102 it wasn't initialized during instantiation.
1103
Brett Cannon3aa2a492008-08-06 22:28:09 +00001104- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1105 the reload() built-in has been removed.
1106
Brett Cannon7e30b672008-08-04 21:52:25 +00001107- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001108 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00001119 asking for a specific length. This problem only affected files opened
1120 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001121

Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001145- Issue #3394: zipfile.writestr sets external attributes when passed a
1146 file name rather than a ZipInfo instance, so files are extracted with
1147 mode 0600 rather than 000 under Unix.
1148
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001149- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1150 argument in python 2.5, this broke code that subclassed Popen to include its

1165 coverage of the lookup process for special methods. The disclaimers
1166 regarding lack of coverage of new-style classes have also been
1167 removed, since the coverage is now fairly reasonable.

1176-----------------
1177
Georg Brandl3e483f62008-07-16 22:57:41 +00001178- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1179 its methods now allow for items objects that can be converted to
1180 an integer using operator.index().
1181
Mark Dickinson64b7e502008-07-16 09:40:03 +00001182- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1183 produced a ValueError instead of giving the correct float.
1184
Eric Smitha5fa5a22008-07-16 00:11:49 +00001185- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1186 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1187
Mark Dickinson7103aa42008-07-15 19:08:33 +00001188- Issue #3008: the float type has a new instance method 'float.hex'
1189 and a new class method 'float.fromhex' to convert floating-point
1190 numbers to and from hexadecimal strings, respectively.
1191
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001192- Issue #2235: __hash__ is once again inherited by default. To allow
1193 collections.Hashable to remain meaningful in the presence of the
1194 default hash implementation (object.__hash__), it is now possible
1195 to explicit block inheritance of hash by setting __hash__=None at
1196 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1197 level.

Nick Coghlanb028f502008-07-13 14:52:36 +00001199- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1200 the parent module cannot be found while performing an absolute import.
1201 This means that an incorrectly defined __package__ attribute will
1202 now only prevent relative imports in that module rather than causing
1203 all imports from that module to fail.

Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001217- Issue #3004: Minor change to slice.indices(): the start and stop
1218 arguments are now treated identically, making the behaviour easier
1219 to describe and understand. For example, slice(None, -10,
1220 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1221 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1222 10, -1).

1265 both unnecessary (HTTP allows text content to be sent in several forms) and

Georg Brandl3ee81df2008-05-17 18:14:43 +00001738- Issue #1631171: Re-implement the 'warnings' module in C (the
1739 original Python code has been kept as backup). This will allow for
1740 using the 'warning's machinery in such places as the parser where
1741 use of pure Python code is not possible. Both the ``showarning()``
1742 and ``formatwarning()`` gain an optional 'line' argument which is
1743 not called by default for backwards-compatibility reasons. Setting
1744 ``warnings.showwarning()`` to an implementation that lacks support
1745 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001808- Issue #2550: The approach used by client/server code for obtaining
1809 ports to listen on in network-oriented tests has been refined in an
1810 effort to facilitate running multiple instances of the entire
1811 regression test suite in parallel without issue.
1812 test_support.bind_port() has been fixed such that it will always
1813 return a unique port -- which wasn't always the case with the
1814 previous implementation, especially if socket options had been set
1815 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1816 new implementation of bind_port() will actually raise an exception
1817 if it is passed an AF_INET/SOCK_STREAM socket with either the
1818 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1819 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1820 the socket it's been passed. This currently only applies to
1821 Windows. This option prevents any other sockets from binding to the
1822 host/port we've bound to, thus removing the possibility of the
1823 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1824 when a second SOCK_STREAM socket binds and accepts to a host/port
1825 that's already been bound by another socket. The optional preferred
1826 port parameter to bind_port() has been removed. Under no
1827 circumstances should tests be hard coding ports!
1828
1829 test_support.find_unused_port() has also been introduced, which will
1830 pass a temporary socket object to bind_port() in order to obtain an
1831 unused port. The temporary socket object is then closed and
1832 deleted, and the port is returned. This method should only be used
1833 for obtaining an unused port in order to pass to an external program
1834 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1835 a parameter to a server-oriented class that doesn't give you direct
1836 access to the underlying socket used.
1837
1838 Finally, test_support.HOST has been introduced, which should be used
1839 for the host argument of any relevant socket calls (i.e. bind and
1840 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00001841
1842 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00001843 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00001844 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
1845 test_asynchat and test_socket_ssl.
1846
Georg Brandl3ee81df2008-05-17 18:14:43 +00001847 It is now possible for multiple instances of the regression test
1848 suite to run in parallel without issue.

2114Core and builtins
2115-----------------
2116
Fred Drakea8ee94b2008-03-01 02:45:07 +00002117- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002118 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002119
Georg Brandlad61bc82008-02-23 15:11:18 +00002120- Issue #2067: file.__exit__() now calls subclasses' close() method.
2121
2122- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002123
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002124- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002125 issue 215555 for a discussion.
2126
Eric Smitha73fbe72008-02-23 03:09:44 +00002127- Added the future_builtins module, which contains hex() and oct().
2128 These are the PEP 3127 version of these functions, designed to be
2129 compatible with the hex() and oct() builtins from Python 3.0. They
2130 differ slightly in their output formats from the existing, unchanged
2131 Python 2.6 builtins. The expected usage of the future_builtins
2132 module is:
2133 from future_builtins import hex, oct
2134
Eric Smith7ef40bf2008-02-20 23:34:22 +00002135- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2136 exponents for exponents with absolute value < 100. Follows C99
2137 standard. This is a change on Windows, which would use 3 digits.
2138 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2139 so that any alterations it does to the resulting string will be
2140 available in stringlib/formatter.h (for float.__format__).
2141
Eric Smith5a3c1352008-02-19 13:21:56 +00002142- Implemented PEP 3101, Advanced String Formatting. This adds a new
2143 builtin format(); a format() method for str and unicode; a
2144 __format__() method to object, str, unicode, int, long, float, and
2145 datetime; the class string.Formatter; and the C API
2146 PyObject_Format().
2147
Georg Brandl3ee81df2008-05-17 18:14:43 +00002148- Fixed several potential crashes, all caused by specially crafted
2149 __del__ methods exploiting objects in temporarily inconsistent
2150 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002151
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002152- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002153 prevent a possible crash: an Abstract Base Class would try to access
2154 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002155
Georg Brandl3ee81df2008-05-17 18:14:43 +00002156- Fixed repr() and str() of complex numbers with infinity or nan as
2157 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002158
Georg Brandl3ee81df2008-05-17 18:14:43 +00002159- Clear all free lists during a gc.collect() of the highest generation
2160 in order to allow pymalloc to free more arenas. Python may give back
2161 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002162
Georg Brandl3ee81df2008-05-17 18:14:43 +00002163- Issue #2045: Fix an infinite recursion triggered when printing a
2164 subclass of collections.defaultdict, if its default_factory is set
2165 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002166
Christian Heimesf75dbef2008-02-08 00:11:31 +00002167- Fixed a minor memory leak in dictobject.c. The content of the free
2168 list was not freed on interpreter shutdown.
2169
Georg Brandl3ee81df2008-05-17 18:14:43 +00002170- Limit free list of method and builtin function objects to 256
2171 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002172
Georg Brandl3ee81df2008-05-17 18:14:43 +00002173- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2174 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002175 to compact the internal free lists of pre-allocted ints and floats.
2176
Georg Brandl3ee81df2008-05-17 18:14:43 +00002177- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2178 calls. Python expected the return type int but the fork familie
2179 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002180
Georg Brandl3ee81df2008-05-17 18:14:43 +00002181- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2182 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002183
Georg Brandl3ee81df2008-05-17 18:14:43 +00002184- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2185 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002186
Georg Brandl3ee81df2008-05-17 18:14:43 +00002187- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2188 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00002189
Georg Brandl3ee81df2008-05-17 18:14:43 +00002190- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2191 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002192
Georg Brandl3ee81df2008-05-17 18:14:43 +00002193- Patch #1473257: generator objects gain a gi_code attribute. This is
2194 the same object as the func_code attribute of the function that
2195 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002196
Georg Brandl3ee81df2008-05-17 18:14:43 +00002197- Issue #1920: "while 0" statements were completely removed by the
2198 compiler, even in the presence of an "else" clause, which is
2199 supposed to be run when the condition is false. Now the compiler
2200 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002201
Guido van Rossumeead05f2008-01-24 18:21:02 +00002202- A few crashers fixed: weakref_in_del.py (issue #1377858);
2203 loosing_dict_ref.py (issue #1303614, test67.py);
2204 borrowed_ref_[34].py (not in tracker).
2205
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002206- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002207 suppressed while an extension is loaded by calling SetErrorMode in
2208 dynload_win.c. The error is still reported properly.
2209
Georg Brandl3ee81df2008-05-17 18:14:43 +00002210- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002211 several extension methods and modules do not work without unicode
2212 support.
2213
Georg Brandl26543b12008-01-21 18:36:51 +00002214- Issue #1882: when compiling code from a string, encoding cookies in the
2215 second line of code were not always recognized correctly.
2216
Georg Brandl14404b62008-01-19 19:27:05 +00002217- Issue #1679: "0x" was taken as a valid integer literal.
2218
Georg Brandl6caad7d2008-01-26 14:19:22 +00002219- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002220 added.
2221
Christian Heimesc94e2b52008-01-14 04:13:37 +00002222- sys.float_info / PyFloat_GetInfo: The floating point information
2223 object was converted from a dict to a specialized structseq object.
2224
Georg Brandl3ee81df2008-05-17 18:14:43 +00002225- Patch #1816: Added sys.flags structseq. It exposes the status of
2226 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002227
Georg Brandl3ee81df2008-05-17 18:14:43 +00002228- Objects/structseq.c: Implemented new structseq representation. The
2229 patch makes structseqs (e.g. the return value of os.stat) more
2230 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002231
Georg Brandl3ee81df2008-05-17 18:14:43 +00002232- Patch #1700288: added a type attribute cache that caches method

2241 envvar and sys.dont_write_bytecode attribute. All these can be set
2242 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002243
Georg Brandl3ee81df2008-05-17 18:14:43 +00002244- Improve some exception messages when Windows fails to load an
2245 extension module. Now we get for example '%1 is not a valid Win32
2246 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002247

Christian Heimes0a8143f2007-12-18 23:22:54 +00002253- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002254 and INF. float("nan"), float("inf") and float("-inf") now work on
2255 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002256
Georg Brandl3ee81df2008-05-17 18:14:43 +00002257- Compiler now generates simpler and faster code for dictionary
2258 literals. The oparg for BUILD_MAP now indicates an estimated
2259 dictionary size. There is a new opcode, STORE_MAP, for adding
2260 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002289- Patch #1739468: Directories and zipfiles containing a __main__.py
2290 file can now be directly executed by passing their name to the
2291 interpreter. The directory/zipfile is automatically inserted as the
2292 first entry in sys.path.

2303
Georg Brandl3ee81df2008-05-17 18:14:43 +00002304- The enumerate() builtin function is no longer bounded to sequences
2305 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2306 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002307
Georg Brandl3ee81df2008-05-17 18:14:43 +00002308- Issue #1686386: Tuple's tp_repr did not take into account the
2309 possibility of having a self-referential tuple, which is possible
2310 from C code. Nor did object's tp_str consider that a type's tp_str
2311 could do something that could lead to an inifinite recursion.
2312 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2313 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002314
Georg Brandl3ee81df2008-05-17 18:14:43 +00002315- Issue #1164: It was possible to trigger deadlock when using the
2316 'print' statement to write to a file since the GIL was not released
2317 as needed. Now PyObject_Print() does the right thing along with
2318 various tp_print implementations of the built-in types and those in
2319 the collections module.

Brett Cannon1e534b52007-09-07 04:18:30 +00002328- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002329 PyObject_Call() never calling back out to Python code to trigger
2330 recursion depth updates/checks. Required the creation of a static
2331 RuntimeError instance in case normalizing an exception put the
2332 recursion check value past its limit. Fixes crashers

Neal Norwitz0ac60192007-05-27 04:08:54 +00002348- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002349 __*__ attributes. (Some already existed, e.g., __doc__ and
2350 __name__.)

2356 calls.
2357
Collin Winter62903052007-05-18 23:11:24 +00002358- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002359 "except E as target:". This is to provide forwards compatibility
2360 with Python 3.0.

2366
Vinay Sajip8549ce32007-05-06 17:53:37 +00002367- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002368 setting a plain string, ie don't expand to single letter identifiers.
2369
Raymond Hettinger13936692007-04-11 18:40:58 +00002370- Request #1191699: Slices can now be pickled.
2371
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002372- Request #1193128: str.translate() now allows a None argument for

2374 remaining characters.
2375
Georg Brandl5cb76c12007-03-21 09:00:39 +00002376- Patch #1682205: a TypeError while unpacking an iterable is no longer

2380
Guido van Rossum143b5642007-03-23 04:58:42 +00002381- Bug #1683368: The object.__init__() and object.__new__() methods are
2382 now stricter in rejecting excess arguments. The only time when
2383 either allows excess arguments is when it is not overridden and the
2384 other one is. For backwards compatibility, when both are
2385 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002386 warning later). Also, type.__init__() insists on the same signature
2387 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002388
Georg Brandl3ee81df2008-05-17 18:14:43 +00002389- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2390 object to complex using its __complex__() method before falling back
2391 to the __float__() method. Therefore, the functions in the cmath
2392 module now can operate on objects that define a __complex__()
2393 method.

2396 __slots__. The old and the new class are still required to have the
2397 same slot names.

2404 its type.

Georg Brandl7b9c5552007-03-12 14:30:05 +00002411- Bug #1678647: write a newline after printing an exception in any
2412 case, even when converting the value to a string failed.
2413
Georg Brandl871f1bc2007-03-12 13:17:36 +00002414- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002415 its argument, if it exists. If not, it will work like before. This
2416 allows customizing the output of dir() in the presence of a
2417 __getattr__().

2421
Georg Brandl3ee81df2008-05-17 18:14:43 +00002422- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00002425- Patch #1491866: change the complex() constructor to allow
2426 parthensized forms. This means complex(repr(x)) now works instead of
2427 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002428
Georg Brandlaa2321b2007-03-07 00:40:28 +00002429- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002430 makes the filenames the warning module prints much more sensible
2431 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00002444- Patch #1674228: when assigning a slice (old-style), check for the
2445 sq_ass_slice instead of the sq_slice slot.
2446
Georg Brandl3ee81df2008-05-17 18:14:43 +00002447- When printing an unraisable error, don't print exceptions. before
2448 the name. This duplicates the behavior whening normally printing
2449 exceptions.

2506
Armin Rigo7ccbca92006-10-04 12:17:45 +00002507- A number of places, including integer negation and absolute value,

3015
Georg Brandl92a6bae2007-03-13 17:43:32 +00003016- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003017 are set for invalid interpolation sequences that would lead to

3074 TestCase and TestSuite subclasses (not instances) are no longer
3075 accepted in TestSuite.addTest(). This should cause no
3076 incompatibility since it never made sense with ordinary subclasses
3077 -- the failure just occurred later, with a more cumbersome
3078 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003359- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3360 with RFC 3207 and forgets any knowledge obtained from the server not
3361 obtained from the TLS negotiation itself. Patch contributed by Bill
3362 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003363
Georg Brandl3ee81df2008-05-17 18:14:43 +00003364- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003365 that the SMTP.starttls() caller no longer needs to call ehlo()
3366 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003367 does not claim to support starttls. Adds the
3368 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +00003423- itertools.chain() now has an alternate constructor,

3449 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3450 silently miscode subclasses of those types. Now, it raises a
3451 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00003452

Georg Brandl3ee81df2008-05-17 18:14:43 +00003467 time so that opening a database previously created with the DB_DUP
3468 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3469 opens. Specifically: dictionary assignment to a DB object will
3470 replace all values for a given key when the database allows
3471 duplicate values. DB users should use DB.put(k, v) when they want
3472 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003473

3479 characters with ASCII value less than 32. Also, it correctly quotes
3480 dots only if they occur on a single line, as opposed to the previous
3481 behavior of quoting dots if they are the second character of any
3482 line.

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00003751- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00003752 periodic threadstate and signal checking in tight loops. By
3753 default, this option is turned-off. It should only be enabled in
3754 debugged, performance critical applications.

3805-----
3806
Georg Brandl3ee81df2008-05-17 18:14:43 +00003807- Unified naming convention for free lists and their limits. All free
3808 lists in Object/ are named ``free_list``, the counter ``numfree``

3810 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00003811
Georg Brandl3ee81df2008-05-17 18:14:43 +00003812- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
3813 to ``PyTuple_SetItem``, it can be used to populate a brand new
3814 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00003815

3826
Georg Brandl3ee81df2008-05-17 18:14:43 +00003827- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
3828 of w# format code incorrectly truncated the length to an int, even
3829 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
3830 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003831
Georg Brandl3ee81df2008-05-17 18:14:43 +00003832- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

3852
3853- Make _PyGILState_NoteThreadState() static, it was not used anywhere
3854 outside of pystate.c and should not be necessary.
3855
Georg Brandl3ee81df2008-05-17 18:14:43 +00003856- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
3857 absolute imports. In earlier versions they might have used relative
3858 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00003859
Georg Brandl3ee81df2008-05-17 18:14:43 +00003860- Added case insensitive comparison methods ``PyOS_stricmp(char*,
3861 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00003862
Georg Brandl3ee81df2008-05-17 18:14:43 +00003863- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00003888- Removed the macfs module. It had been deprecated since Python 2.5.
3889 This lead to the deprecation of macostools.touched() as it relied
