12Core and Builtins
13-----------------
14
Benjamin Peterson5083dc52009-04-25 00:41:22 +000015- Issue #5283: Setting __class__ in __del__ caused a segfault.
16
Mark Dickinson95bc9802009-04-24 12:46:53 +000017- Issue #5816: complex(repr(z)) now recovers z exactly, even when
18 z involves nans, infs or negative zeros.
19
Eric Smithaca19e62009-04-22 13:29:05 +000020- Implement PEP 378, Format Specifier for Thousands Separator, for
21 floats, ints, and longs.
22
23- Issue #5515: 'n' formatting for ints, longs, and floats handles
24 leading zero formatting poorly.
25
26- Issue #5772: For float.__format__, don't add a trailing ".0" if
27 we're using no type code and we have an exponent.
28
Mark Dickinson6736cf82009-04-20 21:13:33 +000029- Issue #3166: Make long -> float (and int -> float) conversions
30 correctly rounded.
31
Benjamin Petersond4d400c2009-04-18 20:12:47 +000032- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
33 some builtin types.
34
Mark Dickinson1bdf7e92009-04-18 14:59:42 +000035- Issue #1869: fix a couple of minor round() issues. round(5e15+1)
36 was giving 5e15+2; round(-0.0) was losing the sign of the zero.
37
Benjamin Peterson99d36f12009-04-15 21:26:36 +000038- Issue #5759: float() didn't call __float__ on str subclasses.
39
Georg Brandl3c4a5462009-04-12 12:08:12 +000040- Issue #5704: the "-3" command-line option now implies "-t".
41
R. David Murray0374a822009-04-09 21:54:50 +000042- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
43 its clarity and its speed.
44
Antoine Pitrou789be0c2009-04-02 21:18:34 +000045- Issue #2396: the memoryview object was backported from Python 3.1.
46
Georg Brandld3f03fa2009-04-02 18:09:04 +000047- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"
48 when hitting the recursion limit under certain circumstances.
49
Brett Cannon15ba4da2009-04-01 18:03:59 +000050- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
51
Ronald Oussorene0154ed2009-03-30 23:10:35 +000052- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
53 the end sys.path, for compatibility with the system install of Python.
54
Antoine Pitrouf8387af2009-03-23 18:41:45 +000055- Issue #4688: Add a heuristic so that tuples and dicts containing only
56 untrackable objects are not tracked by the garbage collector. This can
57 reduce the size of collections and therefore the garbage collection overhead
58 on long-running programs, depending on their particular use of datatypes.
59
Mark Dickinson0b666bf2009-03-23 18:25:13 +000060- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
61 improve its performance. Long divisions and remainder operations
62 are now between 50% and 150% faster.
63
Mark Dickinsonefc82f72009-03-20 15:51:55 +000064- Issue #4258: Make it possible to use base 2**30 instead of base
65 2**15 for the internal representation of integers, for performance
66 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
67 --enable-big-digits option to configure, which overrides the
68 default. Add sys.long_info structseq to provide information about
69 the internal format.
70
Benjamin Peterson6ffe8522009-03-18 20:52:15 +000071- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
72 result traceback.__members__ no longer exists.)
73
Mark Dickinson6b265f12009-03-18 16:07:26 +000074- Issue #4474: PyUnicode_FromWideChar now converts characters outside
75 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
76 and sizeof(Py_UNICODE) == 2.
77
Eric Smith6f42edb2009-03-14 11:57:26 +000078- Issue #5237: Allow auto-numbered fields in str.format(). For
79 example: '{} {}'.format(1, 2) == '1 2'.
80
Brett Cannon6c4cff02009-03-11 04:51:06 +000081- Issue #3652: Make the 'line' argument for warnings.showwarning() a
82 requirement. Means the DeprecationWarning from Python 2.6 can go away.
83
Eric Smithe9fb6862009-02-20 14:02:36 +000084- Issue #5247: Improve error message when unknown format codes are
85 used when using str.format() with str, unicode, long, int, and
86 float arguments.
87
Raymond Hettinger08259e82009-02-18 23:10:19 +000088- Running Python with the -3 option now also warns about classic division
89 for ints and longs.
90
Mark Dickinson2ffb26f2009-02-15 10:13:41 +000091- Issue #5260: Long integers now consume less memory: average
92 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
93 on a 64-bit system.
94
Antoine Pitrou76a4b892009-02-13 13:52:33 +000095- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
96 rotating the object pointer by 4 bits to the right.
97
Mark Dickinsonc97c9092009-02-09 14:18:43 +000098- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
99 it now forces its argument to double before testing for infinity.
100
Benjamin Petersone18ef192009-01-20 14:21:16 +0000101- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
102
Georg Brandl29c6a282009-04-05 20:23:13 +0000103- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000104 were suppressing all exceptions. These include list(), filter(), map(),
105 zip(), and bytearray().
106
Benjamin Peterson596d3062009-01-19 15:42:23 +0000107- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
108 functions.
109
Benjamin Peterson5848d1f2009-01-19 00:08:08 +0000110- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an
111 OSError.
112
Amaury Forgeot d'Arca18392a2009-01-13 23:19:08 +0000113- Issue #4807: Port the _winreg module to Windows CE.
114
Antoine Pitrouc2f02212009-01-13 23:13:52 +0000115- Issue #4935: The overflow checking code in the expandtabs() method common
116 to str, bytes and bytearray could be optimized away by the compiler, letting
117 the interpreter segfault instead of raising an error.
118
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +0000119- Issue #3720: Fix a crash when an iterator modifies its class and removes its
120 __next__ method.
121
Martin v. Löwise3422fa2009-01-12 08:11:24 +0000122- Issue #4893: Use NT threading on CE.

125
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000126- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
127 collecting the oldest generation) so that allocating lots of objects without
128 destroying them does not show quadratic performance. Based on a proposal by
129 Martin von Löwis at
130 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
131
Martin v. Löwisb90304a2009-01-07 18:40:40 +0000132- Issue #4850: Change COUNT_ALLOCS variables to Py_ssize_t.
133
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000134- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
135 an existing .py counterpart, override the co_filename attributes of all
136 code objects if the original filename is obsolete (which can happen if the
137 file has been renamed, moved, or if it is accessed through different paths).
138 Patch by Ziga Seilnacht and Jean-Paul Calderone.
139
Martin v. Löwis5344c992009-01-02 20:32:55 +0000140- Issue #4075: Use OutputDebugStringW in Py_FatalError.
141
Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +0000142- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
143 file with `str' filename on Windows.
144
Antoine Pitrouaa687902009-01-01 14:11:22 +0000145- Issue #3680: Reference cycles created through a dict, set or deque iterator
146 did not get collected.
147
Nick Coghlan180e4002008-12-30 01:18:48 +0000148- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
149 where the tp_hash and tp_dict slots are both NULL.
150
Benjamin Peterson7af65562008-12-29 17:56:58 +0000151- Issue #4764: With io.open, IOError.filename is set when trying to open a
152 directory on POSIX systems.
153
Benjamin Petersonfe231b02008-12-29 17:47:42 +0000154- Issue #4764: IOError.filename is set when trying to open a directory on POSIX

161 fail.
162
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000163- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
164 print elapsed times, not only when some objects are uncollectable /
165 unreachable. Original patch by Neil Schemenauer.
166
Mark Dickinson1a707982008-12-17 16:14:37 +0000167- Issue #3439: Add a bit_length method to int and long.
168
Antoine Pitroud0c35152008-12-17 00:38:28 +0000169- Issue #2183: Simplify and optimize bytecode for list comprehensions.

173 context manager returns a value that cannot be converted to a bool.
174
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000175- Issue #4597: Fixed several opcodes that weren't always propagating
176 exceptions.
177
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000178- Issue #4445: Replace "sizeof(PyStringObject)" with
179 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
180 str instances. On a typical machine this saves 3 bytes of memory
181 (on average) per string allocation.
182
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000183- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
184 interpreter to abort ("Fatal Python error: Could not reset the stack!")
185 instead of throwing a MemoryError.
186

191 module couldn't be imported and \N escapes were present.
192
Vinay Sajip213faca2008-12-03 23:22:58 +0000193- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000194 method on file objects with closefd=False. The file descriptor is still
195 kept open but the file object behaves like a closed file. The ``FileIO``
196 object also got a new readonly attribute ``closefd``.
197
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000198- Issue #4348: Some bytearray methods returned that didn't cause any change to
199 the bytearray, returned the same bytearray instead of a copy.
200
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000201- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
202

206
Benjamin Petersondcee09d2008-10-31 02:16:05 +0000207- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
208 exec statement.
209
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000210- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
211 method does not return iterators for the 4th and 5th items.
212
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000213- Issue #4209: Enabling unicode_literals and the print_function in the same
214 __future__ import didn't work.
215
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000216- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000217 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000218
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000219- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
220 returned a path longer than MAX_PATH. (But It's doubtful this code path is
221 really executed because I cannot move to such directory on win2k)
222
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000223- Issue #4069: When set.remove(element) is used with a set element, the element
224 is temporarily replaced with an equivalent frozenset. But the eventual
225 KeyError would always report the empty frozenset([]) as the missing key. Now
226 it correctly refers to the initial element.
227
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000228- Issue #4509: Various issues surrounding resize of bytearray objects to
229 which there are buffer exports.
230

238 short file names.
239
Matthias Klose91a3b9e2009-04-05 21:19:13 +0000240- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
241 to avoid compiler warnings.
Matthias Klose0610e082009-04-05 12:43:08 +0000242
Gregory P. Smith2b3eb372009-04-05 23:48:26 +0000243- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
244 returned them on 64bit platforms.

974
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000975- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
976 PyString_FromFormat or PyErr_Format to display size_t values. The macro
977 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
978 ``printf`` function, whereas PyString_FromFormat has an independent
979 implementation and uses "%zd" on all platforms for size_t values.
980 This makes a difference on win64, where ``printf`` needs "%Id" to display
981 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +0000983- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

987 object; previously an int would be returned for small values. the __long__
988 method is allowed to return either an int or a long, but the behaviour of
989 float objects should not change to respect backward compatibility.

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +0000991- Issue #3751: str.rpartition would perform a left-partition when called with
992 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +0000997 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +0000998 was correctly parsed but parsing of subsequent arguments failed.
999
Vinay Sajip35e3b032008-09-01 14:33:59 +00001000- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001001 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1002 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1003 when given a tuple of classes as second argument, were looking up
1004 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1005 type object.
1006
Neal Norwitz18aa3882008-08-24 05:04:52 +00001007- Fix crashes on memory allocation failure found with failmalloc.
1008
1009- Fix memory leaks found with valgrind and update suppressions file.
1010
1011- Fix compiler warnings in opt mode which would lead to invalid memory reads.

1150-----------------
1151
Guido van Rossumf8402962008-08-20 15:01:50 +00001152- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1153 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1154 extensions do not automatically benefit from the class attribute
1155 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1156 to their tp_flags field if they care. This is a backwards
1157 compatibility feature; in 3.0, all types will use the cache by
1158 default.
1159
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001160- Keyword arguments can now follow starred arguments. (``f(a, *args,

Georg Brandl1e13ea92008-08-11 09:07:59 +00001170- Issue #3537: Fix an assertion failure when an empty but presized dict
1171 object was stored in the freelist.
1172
Mark Dickinsonb6467572008-08-04 21:30:09 +00001173- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1174 ValueError consistently across platforms.
1175
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001176- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1177 (64bit Unix, for example), unichr() would truncate its argument and return
1178 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1179
Neal Norwitze7d8be82008-07-31 17:17:14 +00001180- Apply security patches from Apple.
1181
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001182- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1183 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1184
Antoine Pitrou92f82162008-07-25 22:22:08 +00001185- Issue #1819: function calls with several named parameters are now on
1186 average 35% faster (as measured by pybench).
1187
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001188- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1189 the python debugger steps into a class statement: the free variables (local
1190 variables defined in an outer scope) would be deleted from the outer scope.
1191
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001192- Issue #2620: Overflow checking when allocating or reallocating memory
1193 was not always being done properly in some python types and extension
1194 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1195 all been updated to perform better checks and places in the code that
1196 would previously leak memory on the error path when such an allocation
1197 failed have been fixed.

1203
Benjamin Petersone977ad42008-08-20 01:42:01 +00001204- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1205 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1206
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001207- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1208 version reported by these tools does not necessarily follow the python
1209 version numbering scheme, so the module is less strict when parsing it.
1210
Nick Coghlanf70385a2008-08-18 12:42:46 +00001211- Issue #2235: Added Py3k warnings for types which will become unhashable
1212 under the stricter __hash__ inheritance rules in 3.0. Several types
1213 which did not meet the rules for hash invariants and were already
1214 unhashable in 3.0 have now been explicitly flagged as unhashable in
1215 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1216 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1217
Brett Cannon88f801d2008-08-18 00:46:22 +00001218- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

1240 after a 302 response in the case of not going through a proxy.
1241
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001242- Issue #2676: in the email package, content-type parsing was hanging on
1243 pathological input because of quadratic or exponential behaviour of a
1244 regular expression.
1245
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001246- Issue #3476: binary buffered reading through the new "io" library is now
1247 thread-safe.
1248
Brett Cannonbf3157b2008-08-14 05:00:03 +00001249- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1250 since mimetools itself is deprecated. Because modules are cached, all
1251 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1252
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001253- Issue #3134: shutil referenced undefined WindowsError symbol.

Robert Schuppenies14646332008-08-10 11:01:53 +00001255- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1256 menu entries were not deleted.
1257
Brett Cannon83e81842008-08-09 23:30:55 +00001258- Copied the implementation of reduce() to _functools.reduce() to have a
1259 version that did not raise a DeprecationWarning under -3.
1260
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001261- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1262 a MemoryError rather than silently stop the iteration.
1263
Guido van Rossum59ce9012008-08-09 14:55:34 +00001264- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1265 to _sre.compile() will now be rejected. This should not affect anybody
1266 since the re.compile() function never generates invalid re-bytecode.
1267
Skip Montanaroa032bf42008-08-08 22:52:51 +00001268- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1269 upon first access it can be automatically initialized from the csv file if
1270 it wasn't initialized during instantiation.
1271
Brett Cannon3aa2a492008-08-06 22:28:09 +00001272- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1273 the reload() built-in has been removed.
1274
Brett Cannon7e30b672008-08-04 21:52:25 +00001275- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001276 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

1284 raised an AttributeError.
1285
Benjamin Peterson01a24322008-07-28 23:35:27 +00001286- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001287 asking for a specific length. This problem only affected files opened
1288 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001289

1312
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001313- Issue #3394: zipfile.writestr sets external attributes when passed a
1314 file name rather than a ZipInfo instance, so files are extracted with
1315 mode 0600 rather than 000 under Unix.
1316
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001317- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1318 argument in python 2.5, this broke code that subclassed Popen to include its
1319 own poll method. Fixed my moving _deadstate to an _internal_poll method.

1328
Nick Coghlan6e8fef02008-08-18 13:14:22 +00001329- Issue #2235: the C API function PyObject_HashNotImplemented and its
1330 interaction with the tp_hash slot (added in 2.6b2) are now documented
1331
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001332- Issue #643841: The language reference now provides more detailed
1333 coverage of the lookup process for special methods. The disclaimers
1334 regarding lack of coverage of new-style classes have also been
1335 removed, since the coverage is now fairly reasonable.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001341*Release date: 17-Jul-2008*
1342
Raymond Hettingere3ae6552008-06-20 04:18:15 +00001343Core and Builtins
1344-----------------
1345
Georg Brandl3e483f62008-07-16 22:57:41 +00001346- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1347 its methods now allow for items objects that can be converted to
1348 an integer using operator.index().
1349
Mark Dickinson64b7e502008-07-16 09:40:03 +00001350- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1351 produced a ValueError instead of giving the correct float.
1352
Eric Smitha5fa5a22008-07-16 00:11:49 +00001353- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1354 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1355
Mark Dickinson7103aa42008-07-15 19:08:33 +00001356- Issue #3008: the float type has a new instance method 'float.hex'
1357 and a new class method 'float.fromhex' to convert floating-point
1358 numbers to and from hexadecimal strings, respectively.
1359
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001360- Issue #2235: __hash__ is once again inherited by default. To allow
1361 collections.Hashable to remain meaningful in the presence of the
1362 default hash implementation (object.__hash__), it is now possible
1363 to explicit block inheritance of hash by setting __hash__=None at
1364 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1365 level.
1366
Nick Coghlanb028f502008-07-13 14:52:36 +00001367- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1368 the parent module cannot be found while performing an absolute import.
1369 This means that an incorrectly defined __package__ attribute will
1370 now only prevent relative imports in that module rather than causing
1371 all imports from that module to fail.
1372
Nick Coghlan14ff9942008-07-08 14:21:42 +00001373- Issue #2517: Allow unicode messages in Exceptions again by correctly
1374 bypassing the instance dictionary when looking up __unicode__ on
1375 new-style classes.
1376
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001377- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1378 set to a custom object whose write() method happens to install
1379 another file in sys.stdout.
1380
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001381- Issue #3088: Corrected a race condition in classes derived from
1382 threading.local: the first member set by a thread could be saved in
1383 another thread's dictionary.
1384
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001385- Issue #3004: Minor change to slice.indices(): the start and stop
1386 arguments are now treated identically, making the behaviour easier
1387 to describe and understand. For example, slice(None, -10,
1388 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1389 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1390 10, -1).
1391
Georg Brandl278fc502008-07-19 12:46:12 +00001392- Issue #3219: Calling a function with repeated keyword arguments,
1393 f(a=2, a=23), would not cause a syntax error. This was a regression
1394 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001395
Georg Brandl278fc502008-07-19 12:46:12 +00001396- Issue #2862: Make int and float freelist management consistent with
1397 other freelists. Changes their CompactFreeList apis into
1398 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00001399

1401-------
1402
Thomas Heller57adf222008-08-14 19:10:48 +00001403- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
1404 api functions without holding the GIL, which could lead to a fatal
1405 error when they failed.
1406
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001407- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

1416 ForkingPickler.register() to resolve conflict with ctypes.
1417
Vinay Sajip51e65192008-07-18 09:01:10 +00001418- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Thomas Heller880f5292008-07-15 19:39:38 +00001420- Issue #3313: Fixed a crash when a failed dlopen() call does not set
1421 a valid dlerror() message.
1422
Thomas Heller2bad6572008-07-15 17:19:50 +00001423- Issue #3258: Fixed a crash when a ctypes POINTER type to an
1424 incomplete structure was created.
1425
Brett Cannon3d0b9f02008-07-13 01:15:07 +00001426- Issue #3339: dummy_thread.acquire() should not return None.
1427
Raymond Hettingerb01713e2008-07-10 14:34:57 +00001428- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
1429
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001430- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00001431
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001432- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1433 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001434 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001435 content-length. The problem had been corrected in the 2.4 branch, but never
1436 merged into trunk.
1437
Georg Brandle78fbcc2008-07-05 10:13:36 +00001438- Issue #2663: add filtering capability to shutil.copytree().

1443
1444- Issue #1746: Correct handling of zipfile archive comments (previously
1445 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00001446 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00001447
Vinay Sajip51e65192008-07-18 09:01:10 +00001448- Issue #449227: The rlcompleter module now adds "(" to callable objects

1843 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00001844 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001845
1846 This is controlled by the configure argument ``--with-universal-archs``:
1847
1848 - ``--with-universal-archs=all``: install 4-way universal
1849
1850 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
1851
1852 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
1853
1854 This option should be used in combination with ``--enable-universalsdk=``.
1855
1856 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00001906- Issue #1631171: Re-implement the 'warnings' module in C (the
1907 original Python code has been kept as backup). This will allow for
1908 using the 'warning's machinery in such places as the parser where
1909 use of pure Python code is not possible. Both the ``showarning()``
1910 and ``formatwarning()`` gain an optional 'line' argument which is
1911 not called by default for backwards-compatibility reasons. Setting
1912 ``warnings.showwarning()`` to an implementation that lacks support
1913 for the ``line`` argument will raise a DeprecationWarning.

1937
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00001938- The getpass module has been improved on Unix. It now uses /dev/tty
1939 by default and uses stderr instead of stdout. A GetPassWarning is
1940 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001976- Issue #2550: The approach used by client/server code for obtaining
1977 ports to listen on in network-oriented tests has been refined in an
1978 effort to facilitate running multiple instances of the entire
1979 regression test suite in parallel without issue.
1980 test_support.bind_port() has been fixed such that it will always
1981 return a unique port -- which wasn't always the case with the
1982 previous implementation, especially if socket options had been set
1983 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1984 new implementation of bind_port() will actually raise an exception
1985 if it is passed an AF_INET/SOCK_STREAM socket with either the
1986 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1987 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1988 the socket it's been passed. This currently only applies to
1989 Windows. This option prevents any other sockets from binding to the
1990 host/port we've bound to, thus removing the possibility of the
1991 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1992 when a second SOCK_STREAM socket binds and accepts to a host/port
1993 that's already been bound by another socket. The optional preferred
1994 port parameter to bind_port() has been removed. Under no
1995 circumstances should tests be hard coding ports!
1996
1997 test_support.find_unused_port() has also been introduced, which will
1998 pass a temporary socket object to bind_port() in order to obtain an
1999 unused port. The temporary socket object is then closed and
2000 deleted, and the port is returned. This method should only be used
2001 for obtaining an unused port in order to pass to an external program
2002 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2003 a parameter to a server-oriented class that doesn't give you direct
2004 access to the underlying socket used.
2005
2006 Finally, test_support.HOST has been introduced, which should be used
2007 for the host argument of any relevant socket calls (i.e. bind and
2008 connect).

2282Core and builtins
2283-----------------
2284
Fred Drakea8ee94b2008-03-01 02:45:07 +00002285- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002286 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002287
Georg Brandlad61bc82008-02-23 15:11:18 +00002288- Issue #2067: file.__exit__() now calls subclasses' close() method.
2289
2290- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002291
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002292- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002293 issue 215555 for a discussion.
2294
Eric Smitha73fbe72008-02-23 03:09:44 +00002295- Added the future_builtins module, which contains hex() and oct().
2296 These are the PEP 3127 version of these functions, designed to be
2297 compatible with the hex() and oct() builtins from Python 3.0. They
2298 differ slightly in their output formats from the existing, unchanged
2299 Python 2.6 builtins. The expected usage of the future_builtins
2300 module is:
2301 from future_builtins import hex, oct
2302
Eric Smith7ef40bf2008-02-20 23:34:22 +00002303- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2304 exponents for exponents with absolute value < 100. Follows C99
2305 standard. This is a change on Windows, which would use 3 digits.
2306 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2307 so that any alterations it does to the resulting string will be
2308 available in stringlib/formatter.h (for float.__format__).
2309
Eric Smith5a3c1352008-02-19 13:21:56 +00002310- Implemented PEP 3101, Advanced String Formatting. This adds a new
2311 builtin format(); a format() method for str and unicode; a
2312 __format__() method to object, str, unicode, int, long, float, and
2313 datetime; the class string.Formatter; and the C API
2314 PyObject_Format().
2315
Georg Brandl3ee81df2008-05-17 18:14:43 +00002316- Fixed several potential crashes, all caused by specially crafted
2317 __del__ methods exploiting objects in temporarily inconsistent
2318 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002319
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002320- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002321 prevent a possible crash: an Abstract Base Class would try to access
2322 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002323
Georg Brandl3ee81df2008-05-17 18:14:43 +00002324- Fixed repr() and str() of complex numbers with infinity or nan as
2325 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002326
Georg Brandl3ee81df2008-05-17 18:14:43 +00002327- Clear all free lists during a gc.collect() of the highest generation
2328 in order to allow pymalloc to free more arenas. Python may give back
2329 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002330
Georg Brandl3ee81df2008-05-17 18:14:43 +00002331- Issue #2045: Fix an infinite recursion triggered when printing a
2332 subclass of collections.defaultdict, if its default_factory is set
2333 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002334
Christian Heimesf75dbef2008-02-08 00:11:31 +00002335- Fixed a minor memory leak in dictobject.c. The content of the free
2336 list was not freed on interpreter shutdown.
2337
Georg Brandl3ee81df2008-05-17 18:14:43 +00002338- Limit free list of method and builtin function objects to 256
2339 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002340
Georg Brandl3ee81df2008-05-17 18:14:43 +00002341- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2342 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002343 to compact the internal free lists of pre-allocted ints and floats.
2344
Georg Brandl3ee81df2008-05-17 18:14:43 +00002345- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2346 calls. Python expected the return type int but the fork familie
2347 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002348
Georg Brandl3ee81df2008-05-17 18:14:43 +00002349- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2350 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002351
Georg Brandl3ee81df2008-05-17 18:14:43 +00002352- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2353 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002354
Georg Brandl3ee81df2008-05-17 18:14:43 +00002355- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2356 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00002357
Georg Brandl3ee81df2008-05-17 18:14:43 +00002358- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2359 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002360
Georg Brandl3ee81df2008-05-17 18:14:43 +00002361- Patch #1473257: generator objects gain a gi_code attribute. This is
2362 the same object as the func_code attribute of the function that
2363 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002364
Georg Brandl3ee81df2008-05-17 18:14:43 +00002365- Issue #1920: "while 0" statements were completely removed by the
2366 compiler, even in the presence of an "else" clause, which is
2367 supposed to be run when the condition is false. Now the compiler
2368 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002369
Guido van Rossumeead05f2008-01-24 18:21:02 +00002370- A few crashers fixed: weakref_in_del.py (issue #1377858);
2371 loosing_dict_ref.py (issue #1303614, test67.py);
2372 borrowed_ref_[34].py (not in tracker).
2373
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002374- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002375 suppressed while an extension is loaded by calling SetErrorMode in
2376 dynload_win.c. The error is still reported properly.
2377
Georg Brandl3ee81df2008-05-17 18:14:43 +00002378- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002379 several extension methods and modules do not work without unicode
2380 support.
2381
Georg Brandl26543b12008-01-21 18:36:51 +00002382- Issue #1882: when compiling code from a string, encoding cookies in the
2383 second line of code were not always recognized correctly.
2384
Georg Brandl14404b62008-01-19 19:27:05 +00002385- Issue #1679: "0x" was taken as a valid integer literal.
2386
Georg Brandl6caad7d2008-01-26 14:19:22 +00002387- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002388 added.
2389
Christian Heimesc94e2b52008-01-14 04:13:37 +00002390- sys.float_info / PyFloat_GetInfo: The floating point information
2391 object was converted from a dict to a specialized structseq object.
2392
Georg Brandl3ee81df2008-05-17 18:14:43 +00002393- Patch #1816: Added sys.flags structseq. It exposes the status of
2394 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002395
Georg Brandl3ee81df2008-05-17 18:14:43 +00002396- Objects/structseq.c: Implemented new structseq representation. The
2397 patch makes structseqs (e.g. the return value of os.stat) more
2398 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002399
Georg Brandl3ee81df2008-05-17 18:14:43 +00002400- Patch #1700288: added a type attribute cache that caches method
2401 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002402
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002403- Bug #1776: __import__() no longer accepts filenames on any platform.
2404 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002405
Georg Brandlaed6c662008-01-07 17:25:53 +00002406- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2407
Georg Brandl3ee81df2008-05-17 18:14:43 +00002408- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2409 envvar and sys.dont_write_bytecode attribute. All these can be set
2410 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002411
Georg Brandl3ee81df2008-05-17 18:14:43 +00002412- Improve some exception messages when Windows fails to load an
2413 extension module. Now we get for example '%1 is not a valid Win32
2414 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002415
Georg Brandl3ee81df2008-05-17 18:14:43 +00002416- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002418- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2419 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002420
Christian Heimes0a8143f2007-12-18 23:22:54 +00002421- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002422 and INF. float("nan"), float("inf") and float("-inf") now work on
2423 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002424
Georg Brandl3ee81df2008-05-17 18:14:43 +00002425- Compiler now generates simpler and faster code for dictionary
2426 literals. The oparg for BUILD_MAP now indicates an estimated
2427 dictionary size. There is a new opcode, STORE_MAP, for adding
2428 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00002429
Georg Brandl3ee81df2008-05-17 18:14:43 +00002430- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002432- Issue #1620: New property decorator syntax was modifying the
2433 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00002434
Georg Brandl3ee81df2008-05-17 18:14:43 +00002435- Issue #1538: Avoid copying string in split/rsplit if the split char
2436 is not found.

Andrew M. Kuchling395fe442007-12-05 13:27:20 +00002438- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00002439 SystemError.
2440
Nick Coghlanef01d822007-12-03 12:55:17 +00002441- PEP 366: Allow explicit relative imports when executing modules
2442 inside packages with the -m switch via a new module level
2443 __package__ attribute.
2444
Georg Brandl3ee81df2008-05-17 18:14:43 +00002445- Issue #1402: Fix a crash on exit, when another thread is still
2446 running, and if the deallocation of its frames somehow calls the
2447 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00002448

2458 file can now be directly executed by passing their name to the
2459 interpreter. The directory/zipfile is automatically inserted as the
2460 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002461
Georg Brandl3ee81df2008-05-17 18:14:43 +00002462- Issue #1265: Fix a problem with sys.settrace, if the tracing
2463 function uses a generator expression when at the same time the
2464 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002465
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002466- sets and frozensets now have an isdisjoint() method.
2467
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00002468- optimize the performance of builtin.sum().
2469
Neal Norwitz44f326e2007-10-05 05:29:17 +00002470- Fix warnings found by the new version of the Coverity checker.
2471
Georg Brandl3ee81df2008-05-17 18:14:43 +00002472- The enumerate() builtin function is no longer bounded to sequences
2473 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2474 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002475
Georg Brandl3ee81df2008-05-17 18:14:43 +00002476- Issue #1686386: Tuple's tp_repr did not take into account the
2477 possibility of having a self-referential tuple, which is possible
2478 from C code. Nor did object's tp_str consider that a type's tp_str
2479 could do something that could lead to an inifinite recursion.
2480 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2481 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002482
Georg Brandl3ee81df2008-05-17 18:14:43 +00002483- Issue #1164: It was possible to trigger deadlock when using the
2484 'print' statement to write to a file since the GIL was not released
2485 as needed. Now PyObject_Print() does the right thing along with
2486 various tp_print implementations of the built-in types and those in
2487 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002489- Issue #1147: Exceptions were directly allowing string exceptions in
2490 their throw() method even though string exceptions no longer
2491 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002492
Georg Brandl3ee81df2008-05-17 18:14:43 +00002493- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00002496- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002497 PyObject_Call() never calling back out to Python code to trigger
2498 recursion depth updates/checks. Required the creation of a static
2499 RuntimeError instance in case normalizing an exception put the
2500 recursion check value past its limit. Fixes crashers
2501 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002502
Georg Brandl3ee81df2008-05-17 18:14:43 +00002503- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00002516- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002517 __*__ attributes. (Some already existed, e.g., __doc__ and
2518 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002519
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002520- Add -3 option to the interpreter to warn about features that are

Georg Brandl3ee81df2008-05-17 18:14:43 +00002527 "except E as target:". This is to provide forwards compatibility
2528 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002529
Brett Cannon229cee22007-05-05 01:34:02 +00002530- Deprecate BaseException.message as per PEP 352.

2548
Guido van Rossum143b5642007-03-23 04:58:42 +00002549- Bug #1683368: The object.__init__() and object.__new__() methods are
2550 now stricter in rejecting excess arguments. The only time when
2551 either allows excess arguments is when it is not overridden and the
2552 other one is. For backwards compatibility, when both are
2553 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002554 warning later). Also, type.__init__() insists on the same signature
2555 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002556
Georg Brandl3ee81df2008-05-17 18:14:43 +00002557- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2558 object to complex using its __complex__() method before falling back
2559 to the __float__() method. Therefore, the functions in the cmath
2560 module now can operate on objects that define a __complex__()
2561 method.

2578
Georg Brandl7b9c5552007-03-12 14:30:05 +00002579- Bug #1678647: write a newline after printing an exception in any
2580 case, even when converting the value to a string failed.
2581
Georg Brandl871f1bc2007-03-12 13:17:36 +00002582- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002583 its argument, if it exists. If not, it will work like before. This
2584 allows customizing the output of dir() in the presence of a
2585 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002586
Collin Winter276887b2007-03-12 16:11:39 +00002587- Patch #922167: Python no longer segfaults when faced with infinitely
2588 self-recursive reload() calls (as reported by bug #742342).

2594 parthensized forms. This means complex(repr(x)) now works instead of
2595 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002596
Georg Brandlaa2321b2007-03-07 00:40:28 +00002597- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002598 makes the filenames the warning module prints much more sensible
2599 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002600

Georg Brandl0fca97a2007-03-05 22:28:08 +00002612- Patch #1674228: when assigning a slice (old-style), check for the
2613 sq_ass_slice instead of the sq_slice slot.
2614
Georg Brandl3ee81df2008-05-17 18:14:43 +00002615- When printing an unraisable error, don't print exceptions. before
2616 the name. This duplicates the behavior whening normally printing
2617 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003241- unittest now verifies more of its assumptions. In particular,
3242 TestCase and TestSuite subclasses (not instances) are no longer
3243 accepted in TestSuite.addTest(). This should cause no
3244 incompatibility since it never made sense with ordinary subclasses
3245 -- the failure just occurred later, with a more cumbersome
3246 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003527- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3528 with RFC 3207 and forgets any knowledge obtained from the server not
3529 obtained from the TLS negotiation itself. Patch contributed by Bill
3530 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003531
Georg Brandl3ee81df2008-05-17 18:14:43 +00003532- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003533 that the SMTP.starttls() caller no longer needs to call ehlo()
3534 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003535 does not claim to support starttls. Adds the
3536 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

3617 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3618 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00003635 time so that opening a database previously created with the DB_DUP
3636 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3637 opens. Specifically: dictionary assignment to a DB object will
3638 replace all values for a given key when the database allows
3639 duplicate values. DB users should use DB.put(k, v) when they want
3640 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003641

3647 characters with ASCII value less than 32. Also, it correctly quotes
3648 dots only if they occur on a single line, as opposed to the previous
3649 behavior of quoting dots if they are the second character of any
3650 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003651

Georg Brandl3ee81df2008-05-17 18:14:43 +00003980- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
3981 to ``PyTuple_SetItem``, it can be used to populate a brand new
3982 frozenset; but it does not steal a reference to the added item.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003986- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
3987 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
3988 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003989
3990- Patch #1720595: add T_BOOL to the range of structmember types.
3991
3992- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
3993 ``PyFloat_GetInfo()`` to the float API.
3994
Georg Brandl3ee81df2008-05-17 18:14:43 +00003995- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
3996 of w# format code incorrectly truncated the length to an int, even
3997 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
3998 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003999
Georg Brandl3ee81df2008-05-17 18:14:43 +00004000- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
4001 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004003- PEP 3123: Provide forward compatibility with Python 3.0, while
4004 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
4005 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004006
Georg Brandl3ee81df2008-05-17 18:14:43 +00004007- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
4008 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004009
4010- Patch #1733960: Allow T_LONGLONG to accept ints.
4011
4012- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
4013
Christian Heimes000a0742008-01-03 22:16:32 +00004014- Added a new API function ``PyImport_ImportModuleNoBlock``.
4015
Georg Brandl6caad7d2008-01-26 14:19:22 +00004016- Bug #1637022: Prefix AST symbols with _Py_.
4017
4018- Fix some leftovers from the conversion from int to Py_ssize_t
4019 (relevant to strings and sequences of more than 2**31 items).
4020
4021- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4022 outside of pystate.c and should not be necessary.
4023
Georg Brandl3ee81df2008-05-17 18:14:43 +00004024- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4025 absolute imports. In earlier versions they might have used relative
4026 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004027
Georg Brandl3ee81df2008-05-17 18:14:43 +00004028- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4029 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004030
Georg Brandl3ee81df2008-05-17 18:14:43 +00004031- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
4032 macro so it can be used as an expression.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004038- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
4039 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
4040 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
4041 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00004042
Georg Brandl3ee81df2008-05-17 18:14:43 +00004043- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Brett Cannon791d56f2007-05-31 19:40:42 +00004054- buildtools now raises a DeprecationWarning.
4055
Georg Brandl3ee81df2008-05-17 18:14:43 +00004056- Removed the macfs module. It had been deprecated since Python 2.5.
4057 This lead to the deprecation of macostools.touched() as it relied
4058 solely on macfs and was a no-op under OS X.
