11
12Core and Builtins
13-----------------
14
Mark Dickinsonefc82f72009-03-20 15:51:55 +000015- Issue #4258: Make it possible to use base 2**30 instead of base
16 2**15 for the internal representation of integers, for performance
17 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
18 --enable-big-digits option to configure, which overrides the
19 default. Add sys.long_info structseq to provide information about
20 the internal format.
21
Benjamin Peterson6ffe8522009-03-18 20:52:15 +000022- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
23 result traceback.__members__ no longer exists.)
24
Mark Dickinson6b265f12009-03-18 16:07:26 +000025- Issue #4474: PyUnicode_FromWideChar now converts characters outside
26 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
27 and sizeof(Py_UNICODE) == 2.
28
Eric Smith6f42edb2009-03-14 11:57:26 +000029- Issue #5237: Allow auto-numbered fields in str.format(). For
30 example: '{} {}'.format(1, 2) == '1 2'.
31
Brett Cannon6c4cff02009-03-11 04:51:06 +000032- Issue #3652: Make the 'line' argument for warnings.showwarning() a
33 requirement. Means the DeprecationWarning from Python 2.6 can go away.
34
Eric Smithe9fb6862009-02-20 14:02:36 +000035- Issue #5247: Improve error message when unknown format codes are
36 used when using str.format() with str, unicode, long, int, and
37 float arguments.
38
Raymond Hettinger08259e82009-02-18 23:10:19 +000039- Running Python with the -3 option now also warns about classic division
40 for ints and longs.
41
Mark Dickinson2ffb26f2009-02-15 10:13:41 +000042- Issue #5260: Long integers now consume less memory: average
43 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
44 on a 64-bit system.
45
Antoine Pitrou76a4b892009-02-13 13:52:33 +000046- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
47 rotating the object pointer by 4 bits to the right.
48
Mark Dickinsonc97c9092009-02-09 14:18:43 +000049- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
50 it now forces its argument to double before testing for infinity.
51
Benjamin Petersone18ef192009-01-20 14:21:16 +000052- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
53
Raymond Hettingerb5163702009-02-02 21:50:13 +000054- Issue 1242657: the __len__() and __length_hint__() calls in several tools
55 were suppressing all exceptions. These include list(), filter(), map(),
56 zip(), and bytearray().
57
Benjamin Peterson596d3062009-01-19 15:42:23 +000058- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
59 functions.
60
Benjamin Peterson5848d1f2009-01-19 00:08:08 +000061- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an

65
Antoine Pitrouc2f02212009-01-13 23:13:52 +000066- Issue #4935: The overflow checking code in the expandtabs() method common
67 to str, bytes and bytearray could be optimized away by the compiler, letting
68 the interpreter segfault instead of raising an error.
69
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +000070- Issue #3720: Fix a crash when an iterator modifies its class and removes its
71 __next__ method.
72

76
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +000077- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
78 collecting the oldest generation) so that allocating lots of objects without
79 destroying them does not show quadratic performance. Based on a proposal by
80 Martin von Löwis at
81 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
82
Martin v. Löwisb90304a2009-01-07 18:40:40 +000083- Issue #4850: Change COUNT_ALLOCS variables to Py_ssize_t.
84
Antoine Pitroue96d4ea2009-01-06 18:10:47 +000085- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
86 an existing .py counterpart, override the co_filename attributes of all
87 code objects if the original filename is obsolete (which can happen if the
88 file has been renamed, moved, or if it is accessed through different paths).
89 Patch by Ziga Seilnacht and Jean-Paul Calderone.
90
Martin v. Löwis5344c992009-01-02 20:32:55 +000091- Issue #4075: Use OutputDebugStringW in Py_FatalError.
92
Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +000093- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
94 file with `str' filename on Windows.
95
Antoine Pitrouaa687902009-01-01 14:11:22 +000096- Issue #3680: Reference cycles created through a dict, set or deque iterator
97 did not get collected.
98
Nick Coghlan180e4002008-12-30 01:18:48 +000099- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
100 where the tp_hash and tp_dict slots are both NULL.
101
Benjamin Peterson7af65562008-12-29 17:56:58 +0000102- Issue #4764: With io.open, IOError.filename is set when trying to open a
103 directory on POSIX systems.
104
Benjamin Petersonfe231b02008-12-29 17:47:42 +0000105- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
106 systems.
107
Georg Brandl6425a2f2008-12-28 11:54:53 +0000108- Issue #4759: None is now allowed as the first argument of
109 bytearray.translate(). It was always allowed for bytes.translate().
110

112 fail.
113
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000114- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
115 print elapsed times, not only when some objects are uncollectable /
116 unreachable. Original patch by Neil Schemenauer.
117
Mark Dickinson1a707982008-12-17 16:14:37 +0000118- Issue #3439: Add a bit_length method to int and long.
119

124 context manager returns a value that cannot be converted to a bool.
125
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000126- Issue #4597: Fixed several opcodes that weren't always propagating
127 exceptions.
128
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000129- Issue #4445: Replace "sizeof(PyStringObject)" with
130 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
131 str instances. On a typical machine this saves 3 bytes of memory
132 (on average) per string allocation.
133
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000134- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
135 interpreter to abort ("Fatal Python error: Could not reset the stack!")
136 instead of throwing a MemoryError.
137
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000138- Issue #3689: The list reversed iterator now supports __length_hint__

142 module couldn't be imported and \N escapes were present.
143
Vinay Sajip213faca2008-12-03 23:22:58 +0000144- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000145 method on file objects with closefd=False. The file descriptor is still
146 kept open but the file object behaves like a closed file. The ``FileIO``
147 object also got a new readonly attribute ``closefd``.
148
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000149- Issue #4348: Some bytearray methods returned that didn't cause any change to
150 the bytearray, returned the same bytearray instead of a copy.
151
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000152- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.

157
Benjamin Petersondcee09d2008-10-31 02:16:05 +0000158- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
159 exec statement.
160
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000161- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
162 method does not return iterators for the 4th and 5th items.
163
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000164- Issue #4209: Enabling unicode_literals and the print_function in the same
165 __future__ import didn't work.
166
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000167- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000168 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000169
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000170- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
171 returned a path longer than MAX_PATH. (But It's doubtful this code path is
172 really executed because I cannot move to such directory on win2k)
173
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000174- Issue #4069: When set.remove(element) is used with a set element, the element
175 is temporarily replaced with an equivalent frozenset. But the eventual
176 KeyError would always report the empty frozenset([]) as the missing key. Now
177 it correctly refers to the initial element.
178
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000179- Issue #4509: Various issues surrounding resize of bytearray objects to
180 which there are buffer exports.
181

Lars Gustäbel2020a592009-03-22 20:09:33 +0000191- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
192 forever on incomplete input. That caused tarfile.open() to hang when used
193 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
194 partial bzip2 compressed data.
195
Benjamin Petersonb364bfe2009-03-22 17:45:11 +0000196- Issue #5536: urllib.urlretrieve makes sure to close the file it's writing to

218 window flashing.
219

756
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000757- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
758 PyString_FromFormat or PyErr_Format to display size_t values. The macro
759 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
760 ``printf`` function, whereas PyString_FromFormat has an independent
761 implementation and uses "%zd" on all platforms for size_t values.
762 This makes a difference on win64, where ``printf`` needs "%Id" to display
763 64bit values.

Antoine Pitrou0668c622008-08-26 22:42:08 +0000783 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
784 mechanism. In the process, fix a bug where isinstance() and issubclass(),

787 type object.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000926What's New in Python 2.6 beta 3?
927================================
928
Barry Warsaw07a4a382008-08-21 01:15:08 +0000929*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000930
931Core and Builtins
932-----------------
933
Guido van Rossumf8402962008-08-20 15:01:50 +0000934- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
935 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
936 extensions do not automatically benefit from the class attribute
937 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
938 to their tp_flags field if they care. This is a backwards
939 compatibility feature; in 3.0, all types will use the cache by
940 default.
941
Benjamin Petersonf647dc12008-08-20 01:27:30 +0000942- Keyword arguments can now follow starred arguments. (``f(a, *args,
943 keyword=23)`` is now valid syntax.)
944
Thomas Heller0ad5ae02008-08-19 19:25:04 +0000945- ctypes function pointers that are COM methods have a boolean True
946 value again.
947
Martin v. Löwisf91d46a2008-08-12 14:49:50 +0000948- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
949 by denying s# to parse objects that have a releasebuffer procedure,
950 and introducing s*.
951
Georg Brandl1e13ea92008-08-11 09:07:59 +0000952- Issue #3537: Fix an assertion failure when an empty but presized dict
953 object was stored in the freelist.
954
Mark Dickinsonb6467572008-08-04 21:30:09 +0000955- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
956 ValueError consistently across platforms.
957
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +0000958- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
959 (64bit Unix, for example), unichr() would truncate its argument and return
960 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
961
Neal Norwitze7d8be82008-07-31 17:17:14 +0000962- Apply security patches from Apple.
963
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +0000964- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
965 PyErr_ExceptionMatches returns 0 when an exception occurs there.
966
Antoine Pitrou92f82162008-07-25 22:22:08 +0000967- Issue #1819: function calls with several named parameters are now on
968 average 35% faster (as measured by pybench).
969
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +0000970- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
971 the python debugger steps into a class statement: the free variables (local
972 variables defined in an outer scope) would be deleted from the outer scope.
973
Gregory P. Smith0470bab2008-07-22 04:46:32 +0000974- Issue #2620: Overflow checking when allocating or reallocating memory
975 was not always being done properly in some python types and extension
976 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
977 all been updated to perform better checks and places in the code that
978 would previously leak memory on the error path when such an allocation
979 failed have been fixed.
980
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000981Library
982-------
983
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +0000984- Issue #3612: Added some missing basic types in ctypes.wintypes.
985
Benjamin Petersone977ad42008-08-20 01:42:01 +0000986- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
987 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
988
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +0000989- Issue #2234: distutils failed for some versions of the cygwin compiler. The
990 version reported by these tools does not necessarily follow the python
991 version numbering scheme, so the module is less strict when parsing it.
992
Nick Coghlanf70385a2008-08-18 12:42:46 +0000993- Issue #2235: Added Py3k warnings for types which will become unhashable
994 under the stricter __hash__ inheritance rules in 3.0. Several types
995 which did not meet the rules for hash invariants and were already
996 unhashable in 3.0 have now been explicitly flagged as unhashable in
997 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
998 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
999
Brett Cannon88f801d2008-08-18 00:46:22 +00001000- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1001 imported into the module but exposed as part of the module's API.
1002
Brett Cannon7b96f072008-08-18 00:41:11 +00001003- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1004
Brett Cannon46225e72008-08-18 00:36:52 +00001005- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
1006
Brett Cannon25c9d6a2008-08-17 22:10:11 +00001007- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1008
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001009- Issue #3575: Incremental decoder's decode function now takes bytearray
1010 by using 's*' instead of 't#'.
1011
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00001012- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001013 fails unicode conversion on 2nd parameter. (windows only)
1014
Facundo Batista94f243a2008-08-17 03:38:39 +00001015- Issue 2464. urllib2 now supports a malformation in the URL received
1016 in a redirect.
1017
Brett Cannonabe423e2008-08-16 21:47:07 +00001018- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001019 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001020
Facundo Batistaeb90b782008-08-16 14:44:07 +00001021- Issue #2776: fixed small issue when handling an URL with double slash
1022 after a 302 response in the case of not going through a proxy.
1023
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001024- Issue #2676: in the email package, content-type parsing was hanging on
1025 pathological input because of quadratic or exponential behaviour of a
1026 regular expression.
1027
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001028- Issue #3476: binary buffered reading through the new "io" library is now
1029 thread-safe.
1030
Brett Cannonbf3157b2008-08-14 05:00:03 +00001031- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1032 since mimetools itself is deprecated. Because modules are cached, all
1033 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1034
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001035- Issue #3134: shutil referenced undefined WindowsError symbol.
1036
Robert Schuppenies14646332008-08-10 11:01:53 +00001037- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1038 menu entries were not deleted.
1039
Brett Cannon83e81842008-08-09 23:30:55 +00001040- Copied the implementation of reduce() to _functools.reduce() to have a
1041 version that did not raise a DeprecationWarning under -3.
1042
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001043- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1044 a MemoryError rather than silently stop the iteration.
1045
Guido van Rossum59ce9012008-08-09 14:55:34 +00001046- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1047 to _sre.compile() will now be rejected. This should not affect anybody
1048 since the re.compile() function never generates invalid re-bytecode.
1049
Skip Montanaroa032bf42008-08-08 22:52:51 +00001050- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1051 upon first access it can be automatically initialized from the csv file if
1052 it wasn't initialized during instantiation.
1053
Brett Cannon3aa2a492008-08-06 22:28:09 +00001054- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1055 the reload() built-in has been removed.
1056
Brett Cannon7e30b672008-08-04 21:52:25 +00001057- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001058 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

1066 raised an AttributeError.
1067
Benjamin Peterson01a24322008-07-28 23:35:27 +00001068- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001069 asking for a specific length. This problem only affected files opened
1070 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001071
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00001072- Issue #3449: Update decimal module to use most recent specification
1073 (v. 1.68) and tests (v. 2.58) from IBM.
1074
Skip Montanarof9ac43f2008-07-27 00:50:41 +00001075- Issue 3437: Bug fix in robotparser parsing of Allow: lines.

1083
1084- Issue #3303: Fix a crash in locale.strcoll() when calling it with
1085 invalid arguments.
1086
1087- Issue #3302: Fix several crashes when calling locale's gettext functions
1088 with None arguments.

1090- Issue #3389: Allow resolving dotted names for handlers in logging
1091 configuration files.
1092
1093- Deprecate the sunaudio module for removal in Python 3.0.
1094
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001095- Issue #3394: zipfile.writestr sets external attributes when passed a
1096 file name rather than a ZipInfo instance, so files are extracted with
1097 mode 0600 rather than 000 under Unix.
1098
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001099- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1100 argument in python 2.5, this broke code that subclassed Popen to include its
1101 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00001111- Issue #2235: the C API function PyObject_HashNotImplemented and its
1112 interaction with the tp_hash slot (added in 2.6b2) are now documented
1113
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001114- Issue #643841: The language reference now provides more detailed
1115 coverage of the lookup process for special methods. The disclaimers
1116 regarding lack of coverage of new-style classes have also been
1117 removed, since the coverage is now fairly reasonable.

1121================================
1122
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001123*Release date: 17-Jul-2008*
1124
Raymond Hettingere3ae6552008-06-20 04:18:15 +00001125Core and Builtins
1126-----------------
1127
Georg Brandl3e483f62008-07-16 22:57:41 +00001128- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1129 its methods now allow for items objects that can be converted to
1130 an integer using operator.index().
1131
Mark Dickinson64b7e502008-07-16 09:40:03 +00001132- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1133 produced a ValueError instead of giving the correct float.
1134
Eric Smitha5fa5a22008-07-16 00:11:49 +00001135- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1136 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1137
Mark Dickinson7103aa42008-07-15 19:08:33 +00001138- Issue #3008: the float type has a new instance method 'float.hex'
1139 and a new class method 'float.fromhex' to convert floating-point
1140 numbers to and from hexadecimal strings, respectively.
1141
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001142- Issue #2235: __hash__ is once again inherited by default. To allow
1143 collections.Hashable to remain meaningful in the presence of the
1144 default hash implementation (object.__hash__), it is now possible
1145 to explicit block inheritance of hash by setting __hash__=None at
1146 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1147 level.
1148
Nick Coghlanb028f502008-07-13 14:52:36 +00001149- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1150 the parent module cannot be found while performing an absolute import.
1151 This means that an incorrectly defined __package__ attribute will
1152 now only prevent relative imports in that module rather than causing
1153 all imports from that module to fail.
1154
Nick Coghlan14ff9942008-07-08 14:21:42 +00001155- Issue #2517: Allow unicode messages in Exceptions again by correctly
1156 bypassing the instance dictionary when looking up __unicode__ on
1157 new-style classes.
1158
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001159- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1160 set to a custom object whose write() method happens to install
1161 another file in sys.stdout.

1165 another thread's dictionary.
1166
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001167- Issue #3004: Minor change to slice.indices(): the start and stop
1168 arguments are now treated identically, making the behaviour easier
1169 to describe and understand. For example, slice(None, -10,
1170 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1171 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1172 10, -1).
1173
Georg Brandl278fc502008-07-19 12:46:12 +00001174- Issue #3219: Calling a function with repeated keyword arguments,
1175 f(a=2, a=23), would not cause a syntax error. This was a regression
1176 from 2.4 caused by the switch to the new compiler.

1187 error when they failed.

Georg Brandl5cc774e2008-06-11 20:28:06 +00001626 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001627
1628 This is controlled by the configure argument ``--with-universal-archs``:
1629
1630 - ``--with-universal-archs=all``: install 4-way universal
1631
1632 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
1633
1634 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
1635
1636 This option should be used in combination with ``--enable-universalsdk=``.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001688- Issue #1631171: Re-implement the 'warnings' module in C (the
1689 original Python code has been kept as backup). This will allow for
1690 using the 'warning's machinery in such places as the parser where
1691 use of pure Python code is not possible. Both the ``showarning()``
1692 and ``formatwarning()`` gain an optional 'line' argument which is
1693 not called by default for backwards-compatibility reasons. Setting
1694 ``warnings.showwarning()`` to an implementation that lacks support
1695 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001750- Issue #2385: distutils.core.run_script() makes __file__ available,
1751 so the controlled environment will more closely mirror the typical
1752 script environment. This supports setup.py scripts that refer to
1753 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001758- Issue #2550: The approach used by client/server code for obtaining
1759 ports to listen on in network-oriented tests has been refined in an
1760 effort to facilitate running multiple instances of the entire
1761 regression test suite in parallel without issue.
1762 test_support.bind_port() has been fixed such that it will always
1763 return a unique port -- which wasn't always the case with the
1764 previous implementation, especially if socket options had been set
1765 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1766 new implementation of bind_port() will actually raise an exception
1767 if it is passed an AF_INET/SOCK_STREAM socket with either the
1768 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1769 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1770 the socket it's been passed. This currently only applies to
1771 Windows. This option prevents any other sockets from binding to the
1772 host/port we've bound to, thus removing the possibility of the
1773 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1774 when a second SOCK_STREAM socket binds and accepts to a host/port
1775 that's already been bound by another socket. The optional preferred
1776 port parameter to bind_port() has been removed. Under no
1777 circumstances should tests be hard coding ports!
1778
1779 test_support.find_unused_port() has also been introduced, which will
1780 pass a temporary socket object to bind_port() in order to obtain an
1781 unused port. The temporary socket object is then closed and
1782 deleted, and the port is returned. This method should only be used
1783 for obtaining an unused port in order to pass to an external program
1784 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1785 a parameter to a server-oriented class that doesn't give you direct
1786 access to the underlying socket used.
1787
1788 Finally, test_support.HOST has been introduced, which should be used
1789 for the host argument of any relevant socket calls (i.e. bind and
1790 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00001791
1792 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00001793 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00001794 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
1795 test_asynchat and test_socket_ssl.
1796
Georg Brandl3ee81df2008-05-17 18:14:43 +00001797 It is now possible for multiple instances of the regression test
1798 suite to run in parallel without issue.

2064Core and builtins
2065-----------------
2066
Fred Drakea8ee94b2008-03-01 02:45:07 +00002067- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002068 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002069
Georg Brandlad61bc82008-02-23 15:11:18 +00002070- Issue #2067: file.__exit__() now calls subclasses' close() method.
2071
2072- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002073
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002074- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002075 issue 215555 for a discussion.
2076
Eric Smitha73fbe72008-02-23 03:09:44 +00002077- Added the future_builtins module, which contains hex() and oct().
2078 These are the PEP 3127 version of these functions, designed to be
2079 compatible with the hex() and oct() builtins from Python 3.0. They
2080 differ slightly in their output formats from the existing, unchanged
2081 Python 2.6 builtins. The expected usage of the future_builtins
2082 module is:
2083 from future_builtins import hex, oct
2084
Eric Smith7ef40bf2008-02-20 23:34:22 +00002085- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2086 exponents for exponents with absolute value < 100. Follows C99
2087 standard. This is a change on Windows, which would use 3 digits.
2088 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2089 so that any alterations it does to the resulting string will be
2090 available in stringlib/formatter.h (for float.__format__).
2091
Eric Smith5a3c1352008-02-19 13:21:56 +00002092- Implemented PEP 3101, Advanced String Formatting. This adds a new
2093 builtin format(); a format() method for str and unicode; a
2094 __format__() method to object, str, unicode, int, long, float, and
2095 datetime; the class string.Formatter; and the C API
2096 PyObject_Format().
2097
Georg Brandl3ee81df2008-05-17 18:14:43 +00002098- Fixed several potential crashes, all caused by specially crafted
2099 __del__ methods exploiting objects in temporarily inconsistent
2100 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002101
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002102- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002103 prevent a possible crash: an Abstract Base Class would try to access
2104 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002105
Georg Brandl3ee81df2008-05-17 18:14:43 +00002106- Fixed repr() and str() of complex numbers with infinity or nan as
2107 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002108
Georg Brandl3ee81df2008-05-17 18:14:43 +00002109- Clear all free lists during a gc.collect() of the highest generation
2110 in order to allow pymalloc to free more arenas. Python may give back
2111 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002112
Georg Brandl3ee81df2008-05-17 18:14:43 +00002113- Issue #2045: Fix an infinite recursion triggered when printing a
2114 subclass of collections.defaultdict, if its default_factory is set
2115 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002116
Christian Heimesf75dbef2008-02-08 00:11:31 +00002117- Fixed a minor memory leak in dictobject.c. The content of the free
2118 list was not freed on interpreter shutdown.
2119
Georg Brandl3ee81df2008-05-17 18:14:43 +00002120- Limit free list of method and builtin function objects to 256
2121 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002122
Georg Brandl3ee81df2008-05-17 18:14:43 +00002123- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2124 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002125 to compact the internal free lists of pre-allocted ints and floats.
2126
Georg Brandl3ee81df2008-05-17 18:14:43 +00002127- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2128 calls. Python expected the return type int but the fork familie
2129 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002130
Georg Brandl3ee81df2008-05-17 18:14:43 +00002131- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2132 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002133

Georg Brandl3ee81df2008-05-17 18:14:43 +00002140- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2141 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002142
Georg Brandl3ee81df2008-05-17 18:14:43 +00002143- Patch #1473257: generator objects gain a gi_code attribute. This is
2144 the same object as the func_code attribute of the function that
2145 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002146
Georg Brandl3ee81df2008-05-17 18:14:43 +00002147- Issue #1920: "while 0" statements were completely removed by the
2148 compiler, even in the presence of an "else" clause, which is
2149 supposed to be run when the condition is false. Now the compiler
2150 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002151
Guido van Rossumeead05f2008-01-24 18:21:02 +00002152- A few crashers fixed: weakref_in_del.py (issue #1377858);
2153 loosing_dict_ref.py (issue #1303614, test67.py);
2154 borrowed_ref_[34].py (not in tracker).
2155
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002156- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002157 suppressed while an extension is loaded by calling SetErrorMode in
2158 dynload_win.c. The error is still reported properly.
2159
Georg Brandl3ee81df2008-05-17 18:14:43 +00002160- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002161 several extension methods and modules do not work without unicode
2162 support.
2163
Georg Brandl26543b12008-01-21 18:36:51 +00002164- Issue #1882: when compiling code from a string, encoding cookies in the
2165 second line of code were not always recognized correctly.
2166
Georg Brandl14404b62008-01-19 19:27:05 +00002167- Issue #1679: "0x" was taken as a valid integer literal.
2168
Georg Brandl6caad7d2008-01-26 14:19:22 +00002169- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002170 added.
2171
Christian Heimesc94e2b52008-01-14 04:13:37 +00002172- sys.float_info / PyFloat_GetInfo: The floating point information
2173 object was converted from a dict to a specialized structseq object.
2174
Georg Brandl3ee81df2008-05-17 18:14:43 +00002175- Patch #1816: Added sys.flags structseq. It exposes the status of
2176 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002177
Georg Brandl3ee81df2008-05-17 18:14:43 +00002178- Objects/structseq.c: Implemented new structseq representation. The
2179 patch makes structseqs (e.g. the return value of os.stat) more
2180 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002181
Georg Brandl3ee81df2008-05-17 18:14:43 +00002182- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00002204 and INF. float("nan"), float("inf") and float("-inf") now work on
2205 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002206
Georg Brandl3ee81df2008-05-17 18:14:43 +00002207- Compiler now generates simpler and faster code for dictionary
2208 literals. The oparg for BUILD_MAP now indicates an estimated
2209 dictionary size. There is a new opcode, STORE_MAP, for adding
2210 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002254- The enumerate() builtin function is no longer bounded to sequences
2255 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2256 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002257
Georg Brandl3ee81df2008-05-17 18:14:43 +00002258- Issue #1686386: Tuple's tp_repr did not take into account the
2259 possibility of having a self-referential tuple, which is possible
2260 from C code. Nor did object's tp_str consider that a type's tp_str
2261 could do something that could lead to an inifinite recursion.
2262 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2263 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002264
Georg Brandl3ee81df2008-05-17 18:14:43 +00002265- Issue #1164: It was possible to trigger deadlock when using the
2266 'print' statement to write to a file since the GIL was not released
2267 as needed. Now PyObject_Print() does the right thing along with
2268 various tp_print implementations of the built-in types and those in
2269 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002270
Georg Brandl3ee81df2008-05-17 18:14:43 +00002271- Issue #1147: Exceptions were directly allowing string exceptions in
2272 their throw() method even though string exceptions no longer
2273 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002274
Georg Brandl3ee81df2008-05-17 18:14:43 +00002275- Issue #1096: Prevent a segfault from getting the repr of a very
2276 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002277
Brett Cannon1e534b52007-09-07 04:18:30 +00002278- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002279 PyObject_Call() never calling back out to Python code to trigger
2280 recursion depth updates/checks. Required the creation of a static
2281 RuntimeError instance in case normalizing an exception put the
2282 recursion check value past its limit. Fixes crashers
2283 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002284

Neal Norwitz0ac60192007-05-27 04:08:54 +00002298- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002299 __*__ attributes. (Some already existed, e.g., __doc__ and
2300 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002301
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002302- Add -3 option to the interpreter to warn about features that are
2303 deprecated and will be changed/removed in Python 3.0.
2304
Georg Brandl2134e752007-05-21 20:34:16 +00002305- Patch #1686487: you can now pass any mapping after '**' in function
2306 calls.
2307
Collin Winter62903052007-05-18 23:11:24 +00002308- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002309 "except E as target:". This is to provide forwards compatibility
2310 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002311
Brett Cannon229cee22007-05-05 01:34:02 +00002312- Deprecate BaseException.message as per PEP 352.
2313
Georg Brandl3ee81df2008-05-17 18:14:43 +00002314- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002315 inherited from a builtin base.
2316
Vinay Sajip8549ce32007-05-06 17:53:37 +00002317- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002318 setting a plain string, ie don't expand to single letter identifiers.
2319
Raymond Hettinger13936692007-04-11 18:40:58 +00002320- Request #1191699: Slices can now be pickled.
2321
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002322- Request #1193128: str.translate() now allows a None argument for
2323 translations that only remove characters without re-mapping the
2324 remaining characters.
2325
Georg Brandl5cb76c12007-03-21 09:00:39 +00002326- Patch #1682205: a TypeError while unpacking an iterable is no longer
2327 masked by a generic one with the message "unpack non-sequence".
2328
Neal Norwitzaa754b72007-03-21 06:39:48 +00002329- Remove unused file Python/fmod.c.
2330
Guido van Rossum143b5642007-03-23 04:58:42 +00002331- Bug #1683368: The object.__init__() and object.__new__() methods are
2332 now stricter in rejecting excess arguments. The only time when
2333 either allows excess arguments is when it is not overridden and the
2334 other one is. For backwards compatibility, when both are
2335 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002336 warning later). Also, type.__init__() insists on the same signature
2337 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002338
Georg Brandl3ee81df2008-05-17 18:14:43 +00002339- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2340 object to complex using its __complex__() method before falling back
2341 to the __float__() method. Therefore, the functions in the cmath
2342 module now can operate on objects that define a __complex__()
2343 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002344
Georg Brandl3ee81df2008-05-17 18:14:43 +00002345- Patch #1623563: allow __class__ assignment for classes with
2346 __slots__. The old and the new class are still required to have the
2347 same slot names.

2353 ``object.__reduce_ex__()`` is called with an object that is faking
2354 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002355
Georg Brandl3ee81df2008-05-17 18:14:43 +00002356- Patch #1680015: Don't modify __slots__ tuple if it contains an

2360
Georg Brandl7b9c5552007-03-12 14:30:05 +00002361- Bug #1678647: write a newline after printing an exception in any
2362 case, even when converting the value to a string failed.
2363
Georg Brandl871f1bc2007-03-12 13:17:36 +00002364- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002365 its argument, if it exists. If not, it will work like before. This
2366 allows customizing the output of dir() in the presence of a
2367 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002368
Collin Winter276887b2007-03-12 16:11:39 +00002369- Patch #922167: Python no longer segfaults when faced with infinitely

2376 parthensized forms. This means complex(repr(x)) now works instead of
2377 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002378
Georg Brandlaa2321b2007-03-07 00:40:28 +00002379- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002380 makes the filenames the warning module prints much more sensible
2381 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002382

Georg Brandl0fca97a2007-03-05 22:28:08 +00002394- Patch #1674228: when assigning a slice (old-style), check for the
2395 sq_ass_slice instead of the sq_slice slot.
2396
Georg Brandl3ee81df2008-05-17 18:14:43 +00002397- When printing an unraisable error, don't print exceptions. before
2398 the name. This duplicates the behavior whening normally printing
2399 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002500 generator expressions (x for x, in ... ) works again. Fixing this
2501 problem required changing the .pyc magic number. This means that
2502 .pyc files generated before 2.5c2 will be regenerated.

3028 exception.

3241 partial fix for Bug #1574584.
3242
Georg Brandl3ee81df2008-05-17 18:14:43 +00003243- Fix turtle so that time.sleep is imported for the entire library.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003309- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3310 with RFC 3207 and forgets any knowledge obtained from the server not
3311 obtained from the TLS negotiation itself. Patch contributed by Bill
3312 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003313
Georg Brandl3ee81df2008-05-17 18:14:43 +00003314- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003315 that the SMTP.starttls() caller no longer needs to call ehlo()
3316 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003317 does not claim to support starttls. Adds the
3318 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

3399 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3400 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00003417 time so that opening a database previously created with the DB_DUP
3418 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3419 opens. Specifically: dictionary assignment to a DB object will
3420 replace all values for a given key when the database allows
3421 duplicate values. DB users should use DB.put(k, v) when they want
3422 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003423

3429 characters with ASCII value less than 32. Also, it correctly quotes
3430 dots only if they occur on a single line, as opposed to the previous
3431 behavior of quoting dots if they are the second character of any
3432 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003433

3755-----
3756
Georg Brandl3ee81df2008-05-17 18:14:43 +00003757- Unified naming convention for free lists and their limits. All free
3758 lists in Object/ are named ``free_list``, the counter ``numfree``
3759 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
3760 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00003761
Georg Brandl3ee81df2008-05-17 18:14:43 +00003762- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
3763 to ``PyTuple_SetItem``, it can be used to populate a brand new
3764 frozenset; but it does not steal a reference to the added item.

3769 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
3770 PyLong_FromSsize_t public functions.

3772- Patch #1720595: add T_BOOL to the range of structmember types.
3773
3774- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
3775 ``PyFloat_GetInfo()`` to the float API.
3776
Georg Brandl3ee81df2008-05-17 18:14:43 +00003777- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
3778 of w# format code incorrectly truncated the length to an int, even
3779 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
3780 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003781
Georg Brandl3ee81df2008-05-17 18:14:43 +00003782- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

3800- Fix some leftovers from the conversion from int to Py_ssize_t
3801 (relevant to strings and sequences of more than 2**31 items).
3802
3803- Make _PyGILState_NoteThreadState() static, it was not used anywhere
3804 outside of pystate.c and should not be necessary.
3805
Georg Brandl3ee81df2008-05-17 18:14:43 +00003806- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
3807 absolute imports. In earlier versions they might have used relative
3808 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00003809
Georg Brandl3ee81df2008-05-17 18:14:43 +00003810- Added case insensitive comparison methods ``PyOS_stricmp(char*,
3811 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00003812
Georg Brandl3ee81df2008-05-17 18:14:43 +00003813- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00003820- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
3821 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
3822 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
3823 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00003824

Georg Brandl3ee81df2008-05-17 18:14:43 +00003838- Removed the macfs module. It had been deprecated since Python 2.5.
3839 This lead to the deprecation of macostools.touched() as it relied
3840 solely on macfs and was a no-op under OS X.
