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

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!")

153 module couldn't be imported and \N escapes were present.
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.

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

221
Gregory P. Smith28399852009-03-31 16:54:10 +0000222- The unittest.TestCase.assertRaises() method now returns a context manager when
223 not given a callable so that code to be tested can be written inline using
224 a with statement.
225
226- The unittest.TestCase.assertEqual() now displays the differences in lists,
227 tuples, dicts and sets on failure. Many new handy type and comparison
228 specific assert* methods have been added that fail with error messages
229 actually useful for debugging. Contributed in part by Google. [Issue #2578]
230
Lars Gustäbel2020a592009-03-22 20:09:33 +0000231- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
232 forever on incomplete input. That caused tarfile.open() to hang when used
233 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or

235
Benjamin Petersonb364bfe2009-03-22 17:45:11 +0000236- Issue #5536: urllib.urlretrieve makes sure to close the file it's writing to

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000797- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
798 PyString_FromFormat or PyErr_Format to display size_t values. The macro
799 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
800 ``printf`` function, whereas PyString_FromFormat has an independent
801 implementation and uses "%zd" on all platforms for size_t values.
802 This makes a difference on win64, where ``printf`` needs "%Id" to display

Antoine Pitrou0668c622008-08-26 22:42:08 +0000823 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
824 mechanism. In the process, fix a bug where isinstance() and issubclass(),

Jesse Noller438195f2009-01-18 21:04:36 +0000922- Issue #4301: Patch the logging module to add processName support, remove
923 _check_logger_class from multiprocessing.
924
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +0000925- Issue #2975: When compiling several extension modules with Visual Studio 2008

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000966What's New in Python 2.6 beta 3?
967================================
968
Barry Warsaw07a4a382008-08-21 01:15:08 +0000969*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000970
971Core and Builtins
972-----------------
973
Guido van Rossumf8402962008-08-20 15:01:50 +0000974- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
975 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
976 extensions do not automatically benefit from the class attribute
977 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
978 to their tp_flags field if they care. This is a backwards
979 compatibility feature; in 3.0, all types will use the cache by
980 default.
981
Benjamin Petersonf647dc12008-08-20 01:27:30 +0000982- Keyword arguments can now follow starred arguments. (``f(a, *args,
983 keyword=23)`` is now valid syntax.)
984
Thomas Heller0ad5ae02008-08-19 19:25:04 +0000985- ctypes function pointers that are COM methods have a boolean True
986 value again.
987
Martin v. Löwisf91d46a2008-08-12 14:49:50 +0000988- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
989 by denying s# to parse objects that have a releasebuffer procedure,
990 and introducing s*.
991
Georg Brandl1e13ea92008-08-11 09:07:59 +0000992- Issue #3537: Fix an assertion failure when an empty but presized dict
993 object was stored in the freelist.
994
Mark Dickinsonb6467572008-08-04 21:30:09 +0000995- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
996 ValueError consistently across platforms.
997
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +0000998- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
999 (64bit Unix, for example), unichr() would truncate its argument and return
1000 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1001
Neal Norwitze7d8be82008-07-31 17:17:14 +00001002- Apply security patches from Apple.
1003
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001004- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1005 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1006
Antoine Pitrou92f82162008-07-25 22:22:08 +00001007- Issue #1819: function calls with several named parameters are now on
1008 average 35% faster (as measured by pybench).
1009
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001010- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1011 the python debugger steps into a class statement: the free variables (local
1012 variables defined in an outer scope) would be deleted from the outer scope.
1013
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001014- Issue #2620: Overflow checking when allocating or reallocating memory
1015 was not always being done properly in some python types and extension
1016 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1017 all been updated to perform better checks and places in the code that
1018 would previously leak memory on the error path when such an allocation
1019 failed have been fixed.
1020
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001021Library
1022-------
1023
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001024- Issue #3612: Added some missing basic types in ctypes.wintypes.
1025
Benjamin Petersone977ad42008-08-20 01:42:01 +00001026- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1027 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1028
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001029- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1030 version reported by these tools does not necessarily follow the python
1031 version numbering scheme, so the module is less strict when parsing it.
1032
Nick Coghlanf70385a2008-08-18 12:42:46 +00001033- Issue #2235: Added Py3k warnings for types which will become unhashable
1034 under the stricter __hash__ inheritance rules in 3.0. Several types
1035 which did not meet the rules for hash invariants and were already
1036 unhashable in 3.0 have now been explicitly flagged as unhashable in
1037 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1038 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1039
Brett Cannon88f801d2008-08-18 00:46:22 +00001040- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1041 imported into the module but exposed as part of the module's API.
1042
Brett Cannon7b96f072008-08-18 00:41:11 +00001043- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1044

1048
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001049- Issue #3575: Incremental decoder's decode function now takes bytearray
1050 by using 's*' instead of 't#'.
1051
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00001052- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001053 fails unicode conversion on 2nd parameter. (windows only)
1054
Facundo Batista94f243a2008-08-17 03:38:39 +00001055- Issue 2464. urllib2 now supports a malformation in the URL received
1056 in a redirect.
1057
Brett Cannonabe423e2008-08-16 21:47:07 +00001058- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001059 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001060
Facundo Batistaeb90b782008-08-16 14:44:07 +00001061- Issue #2776: fixed small issue when handling an URL with double slash
1062 after a 302 response in the case of not going through a proxy.
1063
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001064- Issue #2676: in the email package, content-type parsing was hanging on
1065 pathological input because of quadratic or exponential behaviour of a
1066 regular expression.
1067
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001068- Issue #3476: binary buffered reading through the new "io" library is now
1069 thread-safe.
1070
Brett Cannonbf3157b2008-08-14 05:00:03 +00001071- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1072 since mimetools itself is deprecated. Because modules are cached, all
1073 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1074
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001075- Issue #3134: shutil referenced undefined WindowsError symbol.
1076
Robert Schuppenies14646332008-08-10 11:01:53 +00001077- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1078 menu entries were not deleted.
1079
Brett Cannon83e81842008-08-09 23:30:55 +00001080- Copied the implementation of reduce() to _functools.reduce() to have a
1081 version that did not raise a DeprecationWarning under -3.
1082
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001083- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1084 a MemoryError rather than silently stop the iteration.
1085
Guido van Rossum59ce9012008-08-09 14:55:34 +00001086- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1087 to _sre.compile() will now be rejected. This should not affect anybody
1088 since the re.compile() function never generates invalid re-bytecode.
1089
Skip Montanaroa032bf42008-08-08 22:52:51 +00001090- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1091 upon first access it can be automatically initialized from the csv file if
1092 it wasn't initialized during instantiation.
1093
Brett Cannon3aa2a492008-08-06 22:28:09 +00001094- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1095 the reload() built-in has been removed.
1096
Brett Cannon7e30b672008-08-04 21:52:25 +00001097- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001098 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

1106 raised an AttributeError.
1107

Antoine Pitroude781a42008-08-09 12:43:23 +00001109 asking for a specific length. This problem only affected files opened
1110 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001111

1134
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001135- Issue #3394: zipfile.writestr sets external attributes when passed a
1136 file name rather than a ZipInfo instance, so files are extracted with
1137 mode 0600 rather than 000 under Unix.
1138
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001139- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1140 argument in python 2.5, this broke code that subclassed Popen to include its

1155 coverage of the lookup process for special methods. The disclaimers
1156 regarding lack of coverage of new-style classes have also been
1157 removed, since the coverage is now fairly reasonable.

1162
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001163*Release date: 17-Jul-2008*

1166-----------------
1167
Georg Brandl3e483f62008-07-16 22:57:41 +00001168- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1169 its methods now allow for items objects that can be converted to
1170 an integer using operator.index().
1171
Mark Dickinson64b7e502008-07-16 09:40:03 +00001172- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1173 produced a ValueError instead of giving the correct float.
1174
Eric Smitha5fa5a22008-07-16 00:11:49 +00001175- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1176 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1177
Mark Dickinson7103aa42008-07-15 19:08:33 +00001178- Issue #3008: the float type has a new instance method 'float.hex'
1179 and a new class method 'float.fromhex' to convert floating-point
1180 numbers to and from hexadecimal strings, respectively.
1181
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001182- Issue #2235: __hash__ is once again inherited by default. To allow
1183 collections.Hashable to remain meaningful in the presence of the
1184 default hash implementation (object.__hash__), it is now possible
1185 to explicit block inheritance of hash by setting __hash__=None at
1186 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1187 level.
1188
Nick Coghlanb028f502008-07-13 14:52:36 +00001189- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1190 the parent module cannot be found while performing an absolute import.
1191 This means that an incorrectly defined __package__ attribute will
1192 now only prevent relative imports in that module rather than causing
1193 all imports from that module to fail.
1194
Nick Coghlan14ff9942008-07-08 14:21:42 +00001195- Issue #2517: Allow unicode messages in Exceptions again by correctly

1211 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,

Georg Brandl5cc774e2008-06-11 20:28:06 +00001666 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001667
1668 This is controlled by the configure argument ``--with-universal-archs``:

1672 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
1673
1674 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit

Georg Brandl3ee81df2008-05-17 18:14:43 +00001728- Issue #1631171: Re-implement the 'warnings' module in C (the
1729 original Python code has been kept as backup). This will allow for
1730 using the 'warning's machinery in such places as the parser where
1731 use of pure Python code is not possible. Both the ``showarning()``
1732 and ``formatwarning()`` gain an optional 'line' argument which is
1733 not called by default for backwards-compatibility reasons. Setting
1734 ``warnings.showwarning()`` to an implementation that lacks support
1735 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001798- Issue #2550: The approach used by client/server code for obtaining
1799 ports to listen on in network-oriented tests has been refined in an
1800 effort to facilitate running multiple instances of the entire
1801 regression test suite in parallel without issue.
1802 test_support.bind_port() has been fixed such that it will always
1803 return a unique port -- which wasn't always the case with the
1804 previous implementation, especially if socket options had been set
1805 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1806 new implementation of bind_port() will actually raise an exception
1807 if it is passed an AF_INET/SOCK_STREAM socket with either the
1808 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1809 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1810 the socket it's been passed. This currently only applies to
1811 Windows. This option prevents any other sockets from binding to the
1812 host/port we've bound to, thus removing the possibility of the
1813 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1814 when a second SOCK_STREAM socket binds and accepts to a host/port
1815 that's already been bound by another socket. The optional preferred
1816 port parameter to bind_port() has been removed. Under no
1817 circumstances should tests be hard coding ports!
1818
1819 test_support.find_unused_port() has also been introduced, which will
1820 pass a temporary socket object to bind_port() in order to obtain an
1821 unused port. The temporary socket object is then closed and
1822 deleted, and the port is returned. This method should only be used
1823 for obtaining an unused port in order to pass to an external program
1824 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1825 a parameter to a server-oriented class that doesn't give you direct
1826 access to the underlying socket used.
1827
1828 Finally, test_support.HOST has been introduced, which should be used
1829 for the host argument of any relevant socket calls (i.e. bind and
1830 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00001831
1832 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00001833 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00001834 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
1835 test_asynchat and test_socket_ssl.
1836
Georg Brandl3ee81df2008-05-17 18:14:43 +00001837 It is now possible for multiple instances of the regression test
1838 suite to run in parallel without issue.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002022 optional: it defaults to the traceback of the exception that is
2023 currently being handled (is mandatory to be in the middle of an
2024 exception, otherwise it raises ValueError).

Thomas Hellerf3c05592008-03-05 15:34:29 +00002039- Issue #1872: The struct module typecode for _Bool has been changed
2040 from 't' to '?'.
2041
Thomas Heller78b8f442008-03-05 14:53:39 +00002042- The bundled libffi copy is now in sync with the recently released
2043 libffi3.0.4 version, apart from some small changes to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002044 Modules/_ctypes/libffi/configure.ac. On OS X, preconfigured libffi
2045 files are used. On all linux systems the --with-system-ffi
2046 configure option defaults to "yes".

2104Core and builtins
2105-----------------
2106
Fred Drakea8ee94b2008-03-01 02:45:07 +00002107- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002108 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002109
Georg Brandlad61bc82008-02-23 15:11:18 +00002110- Issue #2067: file.__exit__() now calls subclasses' close() method.
2111
2112- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002113
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002114- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002115 issue 215555 for a discussion.
2116
Eric Smitha73fbe72008-02-23 03:09:44 +00002117- Added the future_builtins module, which contains hex() and oct().
2118 These are the PEP 3127 version of these functions, designed to be
2119 compatible with the hex() and oct() builtins from Python 3.0. They
2120 differ slightly in their output formats from the existing, unchanged
2121 Python 2.6 builtins. The expected usage of the future_builtins
2122 module is:
2123 from future_builtins import hex, oct
2124
Eric Smith7ef40bf2008-02-20 23:34:22 +00002125- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2126 exponents for exponents with absolute value < 100. Follows C99
2127 standard. This is a change on Windows, which would use 3 digits.
2128 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2129 so that any alterations it does to the resulting string will be
2130 available in stringlib/formatter.h (for float.__format__).
2131
Eric Smith5a3c1352008-02-19 13:21:56 +00002132- Implemented PEP 3101, Advanced String Formatting. This adds a new
2133 builtin format(); a format() method for str and unicode; a
2134 __format__() method to object, str, unicode, int, long, float, and
2135 datetime; the class string.Formatter; and the C API
2136 PyObject_Format().
2137
Georg Brandl3ee81df2008-05-17 18:14:43 +00002138- Fixed several potential crashes, all caused by specially crafted
2139 __del__ methods exploiting objects in temporarily inconsistent
2140 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002141
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002142- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002143 prevent a possible crash: an Abstract Base Class would try to access
2144 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002145
Georg Brandl3ee81df2008-05-17 18:14:43 +00002146- Fixed repr() and str() of complex numbers with infinity or nan as
2147 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002148
Georg Brandl3ee81df2008-05-17 18:14:43 +00002149- Clear all free lists during a gc.collect() of the highest generation
2150 in order to allow pymalloc to free more arenas. Python may give back
2151 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002152
Georg Brandl3ee81df2008-05-17 18:14:43 +00002153- Issue #2045: Fix an infinite recursion triggered when printing a
2154 subclass of collections.defaultdict, if its default_factory is set
2155 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002156
Christian Heimesf75dbef2008-02-08 00:11:31 +00002157- Fixed a minor memory leak in dictobject.c. The content of the free
2158 list was not freed on interpreter shutdown.
2159
Georg Brandl3ee81df2008-05-17 18:14:43 +00002160- Limit free list of method and builtin function objects to 256
2161 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002162
Georg Brandl3ee81df2008-05-17 18:14:43 +00002163- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2164 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002165 to compact the internal free lists of pre-allocted ints and floats.
2166
Georg Brandl3ee81df2008-05-17 18:14:43 +00002167- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2168 calls. Python expected the return type int but the fork familie
2169 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002170
Georg Brandl3ee81df2008-05-17 18:14:43 +00002171- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2172 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002173
Georg Brandl3ee81df2008-05-17 18:14:43 +00002174- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2175 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002176
Georg Brandl3ee81df2008-05-17 18:14:43 +00002177- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2178 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00002179
Georg Brandl3ee81df2008-05-17 18:14:43 +00002180- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2181 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002182
Georg Brandl3ee81df2008-05-17 18:14:43 +00002183- Patch #1473257: generator objects gain a gi_code attribute. This is
2184 the same object as the func_code attribute of the function that
2185 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002186
Georg Brandl3ee81df2008-05-17 18:14:43 +00002187- Issue #1920: "while 0" statements were completely removed by the
2188 compiler, even in the presence of an "else" clause, which is
2189 supposed to be run when the condition is false. Now the compiler
2190 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002191
Guido van Rossumeead05f2008-01-24 18:21:02 +00002192- A few crashers fixed: weakref_in_del.py (issue #1377858);
2193 loosing_dict_ref.py (issue #1303614, test67.py);
2194 borrowed_ref_[34].py (not in tracker).
2195
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002196- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002197 suppressed while an extension is loaded by calling SetErrorMode in
2198 dynload_win.c. The error is still reported properly.
2199
Georg Brandl3ee81df2008-05-17 18:14:43 +00002200- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002201 several extension methods and modules do not work without unicode
2202 support.
2203
Georg Brandl26543b12008-01-21 18:36:51 +00002204- Issue #1882: when compiling code from a string, encoding cookies in the
2205 second line of code were not always recognized correctly.
2206
Georg Brandl14404b62008-01-19 19:27:05 +00002207- Issue #1679: "0x" was taken as a valid integer literal.
2208
Georg Brandl6caad7d2008-01-26 14:19:22 +00002209- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002210 added.
2211
Christian Heimesc94e2b52008-01-14 04:13:37 +00002212- sys.float_info / PyFloat_GetInfo: The floating point information
2213 object was converted from a dict to a specialized structseq object.
2214
Georg Brandl3ee81df2008-05-17 18:14:43 +00002215- Patch #1816: Added sys.flags structseq. It exposes the status of
2216 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002217
Georg Brandl3ee81df2008-05-17 18:14:43 +00002218- Objects/structseq.c: Implemented new structseq representation. The
2219 patch makes structseqs (e.g. the return value of os.stat) more
2220 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002221
Georg Brandl3ee81df2008-05-17 18:14:43 +00002222- Patch #1700288: added a type attribute cache that caches method
2223 accesses, resulting in speedups in heavily object-oriented code.

2231 envvar and sys.dont_write_bytecode attribute. All these can be set
2232 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002233
Georg Brandl3ee81df2008-05-17 18:14:43 +00002234- Improve some exception messages when Windows fails to load an
2235 extension module. Now we get for example '%1 is not a valid Win32
2236 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002237

2241 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002242
Christian Heimes0a8143f2007-12-18 23:22:54 +00002243- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002244 and INF. float("nan"), float("inf") and float("-inf") now work on
2245 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002246
Georg Brandl3ee81df2008-05-17 18:14:43 +00002247- Compiler now generates simpler and faster code for dictionary
2248 literals. The oparg for BUILD_MAP now indicates an estimated
2249 dictionary size. There is a new opcode, STORE_MAP, for adding
2250 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002279- Patch #1739468: Directories and zipfiles containing a __main__.py
2280 file can now be directly executed by passing their name to the
2281 interpreter. The directory/zipfile is automatically inserted as the
2282 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002284- Issue #1265: Fix a problem with sys.settrace, if the tracing
2285 function uses a generator expression when at the same time the
2286 executed code is closing a paused generator.

2293
Georg Brandl3ee81df2008-05-17 18:14:43 +00002294- The enumerate() builtin function is no longer bounded to sequences
2295 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2296 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002297
Georg Brandl3ee81df2008-05-17 18:14:43 +00002298- Issue #1686386: Tuple's tp_repr did not take into account the
2299 possibility of having a self-referential tuple, which is possible
2300 from C code. Nor did object's tp_str consider that a type's tp_str
2301 could do something that could lead to an inifinite recursion.
2302 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2303 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002304
Georg Brandl3ee81df2008-05-17 18:14:43 +00002305- Issue #1164: It was possible to trigger deadlock when using the
2306 'print' statement to write to a file since the GIL was not released
2307 as needed. Now PyObject_Print() does the right thing along with
2308 various tp_print implementations of the built-in types and those in
2309 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002311- Issue #1147: Exceptions were directly allowing string exceptions in
2312 their throw() method even though string exceptions no longer
2313 allowed.

Brett Cannona0c05512007-09-10 21:38:27 +00002317
Brett Cannon1e534b52007-09-07 04:18:30 +00002318- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002319 PyObject_Call() never calling back out to Python code to trigger
2320 recursion depth updates/checks. Required the creation of a static
2321 RuntimeError instance in case normalizing an exception put the
2322 recursion check value past its limit. Fixes crashers
2323 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00002338- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002339 __*__ attributes. (Some already existed, e.g., __doc__ and
2340 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002341
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002342- Add -3 option to the interpreter to warn about features that are
2343 deprecated and will be changed/removed in Python 3.0.
2344
Georg Brandl2134e752007-05-21 20:34:16 +00002345- Patch #1686487: you can now pass any mapping after '**' in function
2346 calls.
2347
Collin Winter62903052007-05-18 23:11:24 +00002348- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002349 "except E as target:". This is to provide forwards compatibility
2350 with Python 3.0.

2356
Vinay Sajip8549ce32007-05-06 17:53:37 +00002357- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002358 setting a plain string, ie don't expand to single letter identifiers.
2359
Raymond Hettinger13936692007-04-11 18:40:58 +00002360- Request #1191699: Slices can now be pickled.
2361
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002362- Request #1193128: str.translate() now allows a None argument for
2363 translations that only remove characters without re-mapping the
2364 remaining characters.
2365
Georg Brandl5cb76c12007-03-21 09:00:39 +00002366- Patch #1682205: a TypeError while unpacking an iterable is no longer

2368
Neal Norwitzaa754b72007-03-21 06:39:48 +00002369- Remove unused file Python/fmod.c.
2370
Guido van Rossum143b5642007-03-23 04:58:42 +00002371- Bug #1683368: The object.__init__() and object.__new__() methods are
2372 now stricter in rejecting excess arguments. The only time when
2373 either allows excess arguments is when it is not overridden and the
2374 other one is. For backwards compatibility, when both are
2375 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002376 warning later). Also, type.__init__() insists on the same signature
2377 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002378
Georg Brandl3ee81df2008-05-17 18:14:43 +00002379- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2380 object to complex using its __complex__() method before falling back
2381 to the __float__() method. Therefore, the functions in the cmath
2382 module now can operate on objects that define a __complex__()
2383 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002384
Georg Brandl3ee81df2008-05-17 18:14:43 +00002385- Patch #1623563: allow __class__ assignment for classes with
2386 __slots__. The old and the new class are still required to have the
2387 same slot names.

2393 ``object.__reduce_ex__()`` is called with an object that is faking
2394 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002395
Georg Brandl3ee81df2008-05-17 18:14:43 +00002396- Patch #1680015: Don't modify __slots__ tuple if it contains an

2400
Georg Brandl7b9c5552007-03-12 14:30:05 +00002401- Bug #1678647: write a newline after printing an exception in any
2402 case, even when converting the value to a string failed.
2403
Georg Brandl871f1bc2007-03-12 13:17:36 +00002404- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002405 its argument, if it exists. If not, it will work like before. This
2406 allows customizing the output of dir() in the presence of a
2407 __getattr__().

Collin Winter276887b2007-03-12 16:11:39 +00002409- Patch #922167: Python no longer segfaults when faced with infinitely
2410 self-recursive reload() calls (as reported by bug #742342).
2411
Georg Brandl3ee81df2008-05-17 18:14:43 +00002412- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00002415- Patch #1491866: change the complex() constructor to allow
2416 parthensized forms. This means complex(repr(x)) now works instead of
2417 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002418
Georg Brandlaa2321b2007-03-07 00:40:28 +00002419- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002420 makes the filenames the warning module prints much more sensible
2421 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002422

Georg Brandl098cd692007-03-06 12:17:50 +00002433
Georg Brandl0fca97a2007-03-05 22:28:08 +00002434- Patch #1674228: when assigning a slice (old-style), check for the
2435 sq_ass_slice instead of the sq_slice slot.
2436
Georg Brandl3ee81df2008-05-17 18:14:43 +00002437- When printing an unraisable error, don't print exceptions. before
2438 the name. This duplicates the behavior whening normally printing
2439 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00002440

2496
Armin Rigo7ccbca92006-10-04 12:17:45 +00002497- A number of places, including integer negation and absolute value,

3067 -- the failure just occurred later, with a more cumbersome
3068 exception.

3282
Georg Brandl3ee81df2008-05-17 18:14:43 +00003283- Fix turtle so that time.sleep is imported for the entire library.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003349- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3350 with RFC 3207 and forgets any knowledge obtained from the server not
3351 obtained from the TLS negotiation itself. Patch contributed by Bill
3352 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003353
Georg Brandl3ee81df2008-05-17 18:14:43 +00003354- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003355 that the SMTP.starttls() caller no longer needs to call ehlo()
3356 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003357 does not claim to support starttls. Adds the
3358 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

Georg Brandl3ee81df2008-05-17 18:14:43 +00003413- itertools.chain() now has an alternate constructor,

3439 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3440 silently miscode subclasses of those types. Now, it raises a
3441 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00003442

Georg Brandl3ee81df2008-05-17 18:14:43 +00003457 time so that opening a database previously created with the DB_DUP
3458 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3459 opens. Specifically: dictionary assignment to a DB object will
3460 replace all values for a given key when the database allows
3461 duplicate values. DB users should use DB.put(k, v) when they want
3462 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003463

3469 characters with ASCII value less than 32. Also, it correctly quotes
3470 dots only if they occur on a single line, as opposed to the previous
3471 behavior of quoting dots if they are the second character of any
3472 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003473

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00003741- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00003742 periodic threadstate and signal checking in tight loops. By
3743 default, this option is turned-off. It should only be enabled in
3744 debugged, performance critical applications.

Christian Heimes5b970ad2008-02-06 13:33:44 +00003801
Georg Brandl3ee81df2008-05-17 18:14:43 +00003802- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
3803 to ``PyTuple_SetItem``, it can be used to populate a brand new

3816
Georg Brandl3ee81df2008-05-17 18:14:43 +00003817- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
3818 of w# format code incorrectly truncated the length to an int, even
3819 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
3820 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003821
Georg Brandl3ee81df2008-05-17 18:14:43 +00003822- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

3844 outside of pystate.c and should not be necessary.
3845
Georg Brandl3ee81df2008-05-17 18:14:43 +00003846- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do

3848 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00003849
Georg Brandl3ee81df2008-05-17 18:14:43 +00003850- Added case insensitive comparison methods ``PyOS_stricmp(char*,
3851 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00003852
Georg Brandl3ee81df2008-05-17 18:14:43 +00003853- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00003878- Removed the macfs module. It had been deprecated since Python 2.5.
3879 This lead to the deprecation of macostools.touched() as it relied
