10*Release date: XX-XXX-20XX*
11
12Core and Builtins
13-----------------
14
Raymond Hettinger578a2282009-05-29 04:58:52 +000015- Issue #5982: staticmethod and classmethod now expose the wrapped
16 function with __func__.
17
Raymond Hettinger822b87f2009-05-29 01:46:48 +000018- Added support for multiple context managers in the same with-statement.
19 Deprecated contextlib.nested() which is no longer needed.
Georg Brandl944f6842009-05-25 21:02:56 +000020
Benjamin Peterson1880d8b2009-05-25 13:13:44 +000021- Issue #6101: A new opcode, SETUP_WITH, has been added to speed up the with
22 statement and correctly lookup the __enter__ and __exit__ special methods.
23
Mark Dickinsona4e0efa2009-05-20 18:43:07 +000024- Issue #5829: complex("1e500") no longer raises OverflowError. This
25 makes it consistent with float("1e500") and interpretation of real
26 and imaginary literals.
27
Hirokazu Yamamotoa4f90182009-05-17 02:58:36 +000028- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.
29
Benjamin Peterson0c3b4c62009-05-16 23:34:19 +000030- __instancecheck__ and __subclasscheck__ are now completely ignored on classic
31 classes and instances.
Benjamin Petersoneb9fb2c2009-05-16 22:46:11 +000032
R. David Murray525cffc2009-05-13 13:07:14 +000033- Issue #5994: the marshal module now has docstrings.
34
Mark Dickinsonb1d45852009-05-11 15:33:08 +000035- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
36 (1) inf and nan strings with trailing whitespace were incorrectly
37 rejected; (2) parsing of strings representing infinities and nans
38 was locale aware; and (3) the interpretation of fromhex('-nan')
39 didn't match that of float('-nan').
40
Eric Smitha985a3a2009-05-05 18:26:08 +000041- Issue #5920: For float.__format__, change the behavior with the
42 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
43 to be like 'g' but with at least one decimal point and with a
44 default precision of 12. Previously, the behavior the same but with
45 a default precision of 6. This more closely matches str(), and
46 reduces surprises when adding alignment flags to the empty
47 presentation type. This also affects the new complex.__format__ in
48 the same way.
49
R. David Murray7ba8e1c2009-05-04 22:16:24 +000050- Issue #5890: in subclasses of 'property' the __doc__ attribute was
51 shadowed by classtype's, even if it was None. property now
52 inserts the __doc__ into the subclass instance __dict__.
53
Antoine Pitrou653dece2009-05-04 18:32:32 +000054- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
55 sequences. Patch by Nick Barnes and Victor Stinner.
56
Vinay Sajipf9b01fe2009-05-09 12:07:17 +000057- Issue #1588: Add complex.__format__. For example,
Eric Smith9139cc62009-04-30 00:58:58 +000058 format(complex(1, 2./3), '.5') now produces a sensible result.
59
Mark Dickinson92fcc9c2009-04-29 20:41:00 +000060- Issue #5864: Fix empty format code formatting for floats so that it
61 never gives more than the requested number of significant digits.
62
Eric Smithcac7af62009-04-27 19:04:37 +000063- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
64 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
65
Martin v. Löwis99f27792009-04-26 00:53:18 +000066- Issue #4971: Fix titlecase for characters that are their own
67 titlecase, but not their own uppercase.
68
Eric Smith068f0652009-04-25 21:40:15 +000069- Issue #5835: Deprecate PyOS_ascii_formatd and replace it with
70 _PyOS_double_to_string or PyOS_double_to_string.
71
Benjamin Peterson5083dc52009-04-25 00:41:22 +000072- Issue #5283: Setting __class__ in __del__ caused a segfault.
73
Mark Dickinson95bc9802009-04-24 12:46:53 +000074- Issue #5816: complex(repr(z)) now recovers z exactly, even when
75 z involves nans, infs or negative zeros.
76
Eric Smithaca19e62009-04-22 13:29:05 +000077- Implement PEP 378, Format Specifier for Thousands Separator, for
78 floats, ints, and longs.
79
80- Issue #5515: 'n' formatting for ints, longs, and floats handles
81 leading zero formatting poorly.
82
83- Issue #5772: For float.__format__, don't add a trailing ".0" if
84 we're using no type code and we have an exponent.
85
Mark Dickinson6736cf82009-04-20 21:13:33 +000086- Issue #3166: Make long -> float (and int -> float) conversions
87 correctly rounded.
88
Benjamin Petersond4d400c2009-04-18 20:12:47 +000089- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
90 some builtin types.
91
Mark Dickinson1bdf7e92009-04-18 14:59:42 +000092- Issue #1869: fix a couple of minor round() issues. round(5e15+1)
Eric Smith9139cc62009-04-30 00:58:58 +000093 was giving 5e15+2; round(-0.0) was losing the sign of the zero.
Mark Dickinson1bdf7e92009-04-18 14:59:42 +000094
Benjamin Peterson99d36f12009-04-15 21:26:36 +000095- Issue #5759: float() didn't call __float__ on str subclasses.
96
Georg Brandl3c4a5462009-04-12 12:08:12 +000097- Issue #5704: the "-3" command-line option now implies "-t".
98
R. David Murray0374a822009-04-09 21:54:50 +000099- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
100 its clarity and its speed.
101
Antoine Pitrou789be0c2009-04-02 21:18:34 +0000102- Issue #2396: the memoryview object was backported from Python 3.1.
103
Georg Brandld3f03fa2009-04-02 18:09:04 +0000104- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"
105 when hitting the recursion limit under certain circumstances.
106
Brett Cannon15ba4da2009-04-01 18:03:59 +0000107- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
108
Ronald Oussorene0154ed2009-03-30 23:10:35 +0000109- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
110 the end sys.path, for compatibility with the system install of Python.
111
Antoine Pitrouf8387af2009-03-23 18:41:45 +0000112- Issue #4688: Add a heuristic so that tuples and dicts containing only
113 untrackable objects are not tracked by the garbage collector. This can
114 reduce the size of collections and therefore the garbage collection overhead
115 on long-running programs, depending on their particular use of datatypes.
116
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000117- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
118 improve its performance. Long divisions and remainder operations
119 are now between 50% and 150% faster.
120
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000121- Issue #4258: Make it possible to use base 2**30 instead of base
122 2**15 for the internal representation of integers, for performance
123 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
124 --enable-big-digits option to configure, which overrides the
125 default. Add sys.long_info structseq to provide information about
126 the internal format.
127
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000128- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
129 result traceback.__members__ no longer exists.)
130
Mark Dickinson6b265f12009-03-18 16:07:26 +0000131- Issue #4474: PyUnicode_FromWideChar now converts characters outside
132 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
133 and sizeof(Py_UNICODE) == 2.
134
Eric Smith6f42edb2009-03-14 11:57:26 +0000135- Issue #5237: Allow auto-numbered fields in str.format(). For
136 example: '{} {}'.format(1, 2) == '1 2'.
137
Brett Cannon6c4cff02009-03-11 04:51:06 +0000138- Issue #3652: Make the 'line' argument for warnings.showwarning() a
139 requirement. Means the DeprecationWarning from Python 2.6 can go away.
140
Eric Smithe9fb6862009-02-20 14:02:36 +0000141- Issue #5247: Improve error message when unknown format codes are
142 used when using str.format() with str, unicode, long, int, and
143 float arguments.
144
Raymond Hettinger08259e82009-02-18 23:10:19 +0000145- Running Python with the -3 option now also warns about classic division
146 for ints and longs.
147
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000148- Issue #5260: Long integers now consume less memory: average
149 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
150 on a 64-bit system.
151
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000152- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
153 rotating the object pointer by 4 bits to the right.
154
Mark Dickinsonc97c9092009-02-09 14:18:43 +0000155- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
156 it now forces its argument to double before testing for infinity.
157
Benjamin Petersone18ef192009-01-20 14:21:16 +0000158- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
159
Georg Brandl29c6a282009-04-05 20:23:13 +0000160- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000161 were suppressing all exceptions. These include list(), filter(), map(),
162 zip(), and bytearray().
163
Benjamin Peterson596d3062009-01-19 15:42:23 +0000164- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
165 functions.
166
Benjamin Peterson5848d1f2009-01-19 00:08:08 +0000167- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an

171
Antoine Pitrouc2f02212009-01-13 23:13:52 +0000172- Issue #4935: The overflow checking code in the expandtabs() method common
173 to str, bytes and bytearray could be optimized away by the compiler, letting
174 the interpreter segfault instead of raising an error.
175
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +0000176- Issue #3720: Fix a crash when an iterator modifies its class and removes its
177 __next__ method.

182
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000183- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
184 collecting the oldest generation) so that allocating lots of objects without
185 destroying them does not show quadratic performance. Based on a proposal by
186 Martin von Löwis at
187 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
188
Martin v. Löwisb90304a2009-01-07 18:40:40 +0000189- Issue #4850: Change COUNT_ALLOCS variables to Py_ssize_t.
190
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000191- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
192 an existing .py counterpart, override the co_filename attributes of all
193 code objects if the original filename is obsolete (which can happen if the
194 file has been renamed, moved, or if it is accessed through different paths).
195 Patch by Ziga Seilnacht and Jean-Paul Calderone.
196
Martin v. Löwis5344c992009-01-02 20:32:55 +0000197- Issue #4075: Use OutputDebugStringW in Py_FatalError.
198
Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +0000199- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
200 file with `str' filename on Windows.
201
Antoine Pitrouaa687902009-01-01 14:11:22 +0000202- Issue #3680: Reference cycles created through a dict, set or deque iterator
203 did not get collected.
204
Nick Coghlan180e4002008-12-30 01:18:48 +0000205- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
206 where the tp_hash and tp_dict slots are both NULL.
207
Benjamin Peterson7af65562008-12-29 17:56:58 +0000208- Issue #4764: With io.open, IOError.filename is set when trying to open a
209 directory on POSIX systems.
210
Benjamin Petersonfe231b02008-12-29 17:47:42 +0000211- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
212 systems.
213
Georg Brandl6425a2f2008-12-28 11:54:53 +0000214- Issue #4759: None is now allowed as the first argument of

218 fail.
219
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000220- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
221 print elapsed times, not only when some objects are uncollectable /
222 unreachable. Original patch by Neil Schemenauer.
223
Mark Dickinson1a707982008-12-17 16:14:37 +0000224- Issue #3439: Add a bit_length method to int and long.

228
Amaury Forgeot d'Arcad9b5992008-12-10 23:22:49 +0000229- Issue #4597: Fixed exception handling when the __exit__ function of a
230 context manager returns a value that cannot be converted to a bool.
231
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000232- Issue #4597: Fixed several opcodes that weren't always propagating
233 exceptions.
234
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000235- Issue #4445: Replace "sizeof(PyStringObject)" with
236 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
237 str instances. On a typical machine this saves 3 bytes of memory
238 (on average) per string allocation.
239
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000240- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
241 interpreter to abort ("Fatal Python error: Could not reset the stack!")

249
Vinay Sajip213faca2008-12-03 23:22:58 +0000250- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000251 method on file objects with closefd=False. The file descriptor is still
252 kept open but the file object behaves like a closed file. The ``FileIO``
253 object also got a new readonly attribute ``closefd``.
254
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000255- Issue #4348: Some bytearray methods returned that didn't cause any change to
256 the bytearray, returned the same bytearray instead of a copy.
257

261
Benjamin Peterson6624a9f2008-11-03 15:14:51 +0000262- Issue #4048: The parser module now correctly validates relative imports.
263
Benjamin Petersondcee09d2008-10-31 02:16:05 +0000264- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
265 exec statement.
266
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000267- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
268 method does not return iterators for the 4th and 5th items.
269
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000270- Issue #4209: Enabling unicode_literals and the print_function in the same
271 __future__ import didn't work.
272
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000273- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000274 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000275
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000276- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
277 returned a path longer than MAX_PATH. (But It's doubtful this code path is
278 really executed because I cannot move to such directory on win2k)
279
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000280- Issue #4069: When set.remove(element) is used with a set element, the element
281 is temporarily replaced with an equivalent frozenset. But the eventual
282 KeyError would always report the empty frozenset([]) as the missing key. Now
283 it correctly refers to the initial element.
284
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000285- Issue #4509: Various issues surrounding resize of bytearray objects to
286 which there are buffer exports.

295 short file names.
296
Matthias Klose91a3b9e2009-04-05 21:19:13 +0000297- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
298 to avoid compiler warnings.

Walter Dörwalded960ac2009-05-03 22:36:33 +0000303- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
304 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
305 step. This avoids problems with counting UTF-8 bytes that ignores the effect
306 of using the replace error handler in PyUnicode_DecodeUTF8().
307

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001207- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1208
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001209- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1210 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1211 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1212 ``printf`` function, whereas PyString_FromFormat has an independent
1213 implementation and uses "%zd" on all platforms for size_t values.
1214 This makes a difference on win64, where ``printf`` needs "%Id" to display
1215 64bit values.
1216
Benjamin Peterson97179b02008-09-09 20:55:01 +00001217- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
1218 error.
1219
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00001220- Issue #3777: long() applied to a float object now always return a long
1221 object; previously an int would be returned for small values. the __long__
1222 method is allowed to return either an int or a long, but the behaviour of
1223 float objects should not change to respect backward compatibility.
1224
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001225- Issue #3751: str.rpartition would perform a left-partition when called with
1226 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +00001231 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001232 was correctly parsed but parsing of subsequent arguments failed.
1233
Vinay Sajip35e3b032008-09-01 14:33:59 +00001234- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001235 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1236 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1237 when given a tuple of classes as second argument, were looking up
1238 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1239 type object.
1240
Neal Norwitz18aa3882008-08-24 05:04:52 +00001241- Fix crashes on memory allocation failure found with failmalloc.

1311 for catch_warnings() also led to an improvement in the raising of a

1384-----------------
1385
Guido van Rossumf8402962008-08-20 15:01:50 +00001386- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1387 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1388 extensions do not automatically benefit from the class attribute
1389 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1390 to their tp_flags field if they care. This is a backwards
1391 compatibility feature; in 3.0, all types will use the cache by
1392 default.
1393
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001394- Keyword arguments can now follow starred arguments. (``f(a, *args,
1395 keyword=23)`` is now valid syntax.)
1396
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001397- ctypes function pointers that are COM methods have a boolean True
1398 value again.
1399
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001400- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1401 by denying s# to parse objects that have a releasebuffer procedure,
1402 and introducing s*.
1403
Georg Brandl1e13ea92008-08-11 09:07:59 +00001404- Issue #3537: Fix an assertion failure when an empty but presized dict
1405 object was stored in the freelist.
1406
Mark Dickinsonb6467572008-08-04 21:30:09 +00001407- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1408 ValueError consistently across platforms.
1409
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001410- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1411 (64bit Unix, for example), unichr() would truncate its argument and return
1412 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1413
Neal Norwitze7d8be82008-07-31 17:17:14 +00001414- Apply security patches from Apple.
1415
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001416- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1417 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1418
Antoine Pitrou92f82162008-07-25 22:22:08 +00001419- Issue #1819: function calls with several named parameters are now on
1420 average 35% faster (as measured by pybench).
1421
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001422- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1423 the python debugger steps into a class statement: the free variables (local
1424 variables defined in an outer scope) would be deleted from the outer scope.
1425
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001426- Issue #2620: Overflow checking when allocating or reallocating memory
1427 was not always being done properly in some python types and extension
1428 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1429 all been updated to perform better checks and places in the code that
1430 would previously leak memory on the error path when such an allocation
1431 failed have been fixed.

1437
Benjamin Petersone977ad42008-08-20 01:42:01 +00001438- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1439 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1440
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001441- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1442 version reported by these tools does not necessarily follow the python
1443 version numbering scheme, so the module is less strict when parsing it.
1444
Nick Coghlanf70385a2008-08-18 12:42:46 +00001445- Issue #2235: Added Py3k warnings for types which will become unhashable
1446 under the stricter __hash__ inheritance rules in 3.0. Several types

Antoine Pitroude781a42008-08-09 12:43:23 +00001521 asking for a specific length. This problem only affected files opened

1565
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001566- Issue #643841: The language reference now provides more detailed

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001577Core and Builtins
1578-----------------
1579
Georg Brandl3e483f62008-07-16 22:57:41 +00001580- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1581 its methods now allow for items objects that can be converted to
1582 an integer using operator.index().
1583
Mark Dickinson64b7e502008-07-16 09:40:03 +00001584- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1585 produced a ValueError instead of giving the correct float.
1586
Eric Smitha5fa5a22008-07-16 00:11:49 +00001587- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1588 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1589
Mark Dickinson7103aa42008-07-15 19:08:33 +00001590- Issue #3008: the float type has a new instance method 'float.hex'
1591 and a new class method 'float.fromhex' to convert floating-point
1592 numbers to and from hexadecimal strings, respectively.
1593
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001594- Issue #2235: __hash__ is once again inherited by default. To allow
1595 collections.Hashable to remain meaningful in the presence of the
1596 default hash implementation (object.__hash__), it is now possible
1597 to explicit block inheritance of hash by setting __hash__=None at
1598 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1599 level.
1600
Nick Coghlanb028f502008-07-13 14:52:36 +00001601- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1602 the parent module cannot be found while performing an absolute import.
1603 This means that an incorrectly defined __package__ attribute will
1604 now only prevent relative imports in that module rather than causing
1605 all imports from that module to fail.
1606
Nick Coghlan14ff9942008-07-08 14:21:42 +00001607- Issue #2517: Allow unicode messages in Exceptions again by correctly
1608 bypassing the instance dictionary when looking up __unicode__ on
1609 new-style classes.

1612 set to a custom object whose write() method happens to install
1613 another file in sys.stdout.

Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001615- Issue #3088: Corrected a race condition in classes derived from
1616 threading.local: the first member set by a thread could be saved in
1617 another thread's dictionary.
1618
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001619- Issue #3004: Minor change to slice.indices(): the start and stop
1620 arguments are now treated identically, making the behaviour easier
1621 to describe and understand. For example, slice(None, -10,
1622 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1623 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1624 10, -1).
1625
Georg Brandl278fc502008-07-19 12:46:12 +00001626- Issue #3219: Calling a function with repeated keyword arguments,
1627 f(a=2, a=23), would not cause a syntax error. This was a regression
1628 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001629
Georg Brandl278fc502008-07-19 12:46:12 +00001630- Issue #2862: Make int and float freelist management consistent with
1631 other freelists. Changes their CompactFreeList apis into

1638 api functions without holding the GIL, which could lead to a fatal
1639 error when they failed.
1640
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001641- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001666- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1667 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001668 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001669 content-length. The problem had been corrected in the 2.4 branch, but never
1670 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001685- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

2077 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002078 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002079
2080 This is controlled by the configure argument ``--with-universal-archs``:
2081
2082 - ``--with-universal-archs=all``: install 4-way universal
2083
2084 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2085
2086 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2087
2088 This option should be used in combination with ``--enable-universalsdk=``.
2089
2090 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 +00002140- Issue #1631171: Re-implement the 'warnings' module in C (the
2141 original Python code has been kept as backup). This will allow for
2142 using the 'warning's machinery in such places as the parser where
2143 use of pure Python code is not possible. Both the ``showarning()``
2144 and ``formatwarning()`` gain an optional 'line' argument which is
2145 not called by default for backwards-compatibility reasons. Setting
2146 ``warnings.showwarning()`` to an implementation that lacks support
2147 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002210- Issue #2550: The approach used by client/server code for obtaining
2211 ports to listen on in network-oriented tests has been refined in an
2212 effort to facilitate running multiple instances of the entire
2213 regression test suite in parallel without issue.
2214 test_support.bind_port() has been fixed such that it will always
2215 return a unique port -- which wasn't always the case with the
2216 previous implementation, especially if socket options had been set
2217 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2218 new implementation of bind_port() will actually raise an exception
2219 if it is passed an AF_INET/SOCK_STREAM socket with either the
2220 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2221 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2222 the socket it's been passed. This currently only applies to
2223 Windows. This option prevents any other sockets from binding to the
2224 host/port we've bound to, thus removing the possibility of the
2225 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2226 when a second SOCK_STREAM socket binds and accepts to a host/port
2227 that's already been bound by another socket. The optional preferred
2228 port parameter to bind_port() has been removed. Under no
2229 circumstances should tests be hard coding ports!
2230
2231 test_support.find_unused_port() has also been introduced, which will
2232 pass a temporary socket object to bind_port() in order to obtain an
2233 unused port. The temporary socket object is then closed and
2234 deleted, and the port is returned. This method should only be used
2235 for obtaining an unused port in order to pass to an external program
2236 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2237 a parameter to a server-oriented class that doesn't give you direct
2238 access to the underlying socket used.
2239
2240 Finally, test_support.HOST has been introduced, which should be used
2241 for the host argument of any relevant socket calls (i.e. bind and
2242 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002243
2244 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002245 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002246 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2247 test_asynchat and test_socket_ssl.
2248
Georg Brandl3ee81df2008-05-17 18:14:43 +00002249 It is now possible for multiple instances of the regression test
2250 suite to run in parallel without issue.

2303
Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00002304- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00002305 \Uxxxxxxxx did not accept values outside the Basic Multilingual
2306 Plane. This affected raw unicode literals and the
2307 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
2308 this case, like normal unicode literals and the 'unicode-escape'
2309 codec.

2517-----------------
2518
Fred Drakea8ee94b2008-03-01 02:45:07 +00002519- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002520 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00002522- Issue #2067: file.__exit__() now calls subclasses' close() method.
2523
2524- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002525
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002526- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002527 issue 215555 for a discussion.
2528
Eric Smitha73fbe72008-02-23 03:09:44 +00002529- Added the future_builtins module, which contains hex() and oct().
2530 These are the PEP 3127 version of these functions, designed to be
2531 compatible with the hex() and oct() builtins from Python 3.0. They
2532 differ slightly in their output formats from the existing, unchanged
2533 Python 2.6 builtins. The expected usage of the future_builtins
2534 module is:
2535 from future_builtins import hex, oct
2536
Eric Smith7ef40bf2008-02-20 23:34:22 +00002537- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2538 exponents for exponents with absolute value < 100. Follows C99
2539 standard. This is a change on Windows, which would use 3 digits.
2540 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2541 so that any alterations it does to the resulting string will be
2542 available in stringlib/formatter.h (for float.__format__).
2543
Eric Smith5a3c1352008-02-19 13:21:56 +00002544- Implemented PEP 3101, Advanced String Formatting. This adds a new
2545 builtin format(); a format() method for str and unicode; a
2546 __format__() method to object, str, unicode, int, long, float, and
2547 datetime; the class string.Formatter; and the C API
2548 PyObject_Format().
2549
Georg Brandl3ee81df2008-05-17 18:14:43 +00002550- Fixed several potential crashes, all caused by specially crafted
2551 __del__ methods exploiting objects in temporarily inconsistent
2552 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002553
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002554- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002555 prevent a possible crash: an Abstract Base Class would try to access
2556 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002557

Georg Brandl3ee81df2008-05-17 18:14:43 +00002561- Clear all free lists during a gc.collect() of the highest generation
2562 in order to allow pymalloc to free more arenas. Python may give back
2563 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002564
Georg Brandl3ee81df2008-05-17 18:14:43 +00002565- Issue #2045: Fix an infinite recursion triggered when printing a

Georg Brandl3ee81df2008-05-17 18:14:43 +00002595- Patch #1473257: generator objects gain a gi_code attribute. This is
2596 the same object as the func_code attribute of the function that
2597 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002598
Georg Brandl3ee81df2008-05-17 18:14:43 +00002599- Issue #1920: "while 0" statements were completely removed by the
2600 compiler, even in the presence of an "else" clause, which is
2601 supposed to be run when the condition is false. Now the compiler
2602 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002603
Guido van Rossumeead05f2008-01-24 18:21:02 +00002604- A few crashers fixed: weakref_in_del.py (issue #1377858);
2605 loosing_dict_ref.py (issue #1303614, test67.py);
2606 borrowed_ref_[34].py (not in tracker).

Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002608- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002609 suppressed while an extension is loaded by calling SetErrorMode in
2610 dynload_win.c. The error is still reported properly.
2611
Georg Brandl3ee81df2008-05-17 18:14:43 +00002612- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002613 several extension methods and modules do not work without unicode
2614 support.
2615
Georg Brandl26543b12008-01-21 18:36:51 +00002616- Issue #1882: when compiling code from a string, encoding cookies in the

2620
Georg Brandl6caad7d2008-01-26 14:19:22 +00002621- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002622 added.
2623
Christian Heimesc94e2b52008-01-14 04:13:37 +00002624- sys.float_info / PyFloat_GetInfo: The floating point information
2625 object was converted from a dict to a specialized structseq object.
2626
Georg Brandl3ee81df2008-05-17 18:14:43 +00002627- Patch #1816: Added sys.flags structseq. It exposes the status of
2628 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002629
Georg Brandl3ee81df2008-05-17 18:14:43 +00002630- Objects/structseq.c: Implemented new structseq representation. The
2631 patch makes structseqs (e.g. the return value of os.stat) more
2632 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002633
Georg Brandl3ee81df2008-05-17 18:14:43 +00002634- Patch #1700288: added a type attribute cache that caches method
2635 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002636
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002637- Bug #1776: __import__() no longer accepts filenames on any platform.
2638 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002639

2643 envvar and sys.dont_write_bytecode attribute. All these can be set
2644 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002645
Georg Brandl3ee81df2008-05-17 18:14:43 +00002646- Improve some exception messages when Windows fails to load an
2647 extension module. Now we get for example '%1 is not a valid Win32
2648 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002649

2705
Georg Brandl3ee81df2008-05-17 18:14:43 +00002706- The enumerate() builtin function is no longer bounded to sequences
2707 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2708 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002709
Georg Brandl3ee81df2008-05-17 18:14:43 +00002710- Issue #1686386: Tuple's tp_repr did not take into account the
2711 possibility of having a self-referential tuple, which is possible
2712 from C code. Nor did object's tp_str consider that a type's tp_str
2713 could do something that could lead to an inifinite recursion.
2714 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2715 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002716
Georg Brandl3ee81df2008-05-17 18:14:43 +00002717- Issue #1164: It was possible to trigger deadlock when using the
2718 'print' statement to write to a file since the GIL was not released
2719 as needed. Now PyObject_Print() does the right thing along with
2720 various tp_print implementations of the built-in types and those in
2721 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002731 PyObject_Call() never calling back out to Python code to trigger
2732 recursion depth updates/checks. Required the creation of a static
2733 RuntimeError instance in case normalizing an exception put the
2734 recursion check value past its limit. Fixes crashers

2758 calls.
2759
Collin Winter62903052007-05-18 23:11:24 +00002760- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002761 "except E as target:". This is to provide forwards compatibility
2762 with Python 3.0.

2784 now stricter in rejecting excess arguments. The only time when
2785 either allows excess arguments is when it is not overridden and the
2786 other one is. For backwards compatibility, when both are
2787 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002788 warning later). Also, type.__init__() insists on the same signature
2789 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00002791- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2792 object to complex using its __complex__() method before falling back
2793 to the __float__() method. Therefore, the functions in the cmath
2794 module now can operate on objects that define a __complex__()
2795 method.

2815
Georg Brandl871f1bc2007-03-12 13:17:36 +00002816- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002817 its argument, if it exists. If not, it will work like before. This
2818 allows customizing the output of dir() in the presence of a
2819 __getattr__().

Georg Brandlaa2321b2007-03-07 00:40:28 +00002831- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002832 makes the filenames the warning module prints much more sensible
2833 when a PYTHONSTARTUP file is used.

2848
Georg Brandl3ee81df2008-05-17 18:14:43 +00002849- When printing an unraisable error, don't print exceptions. before

Georg Brandl2c1375c2006-10-12 11:27:59 +00002901- Bug #1545497: when given an explicit base, int() did ignore NULs
2902 embedded in the string to convert.
2903
Georg Brandl846f73a2006-10-08 07:11:54 +00002904- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00003761- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3762 with RFC 3207 and forgets any knowledge obtained from the server not
3763 obtained from the TLS negotiation itself. Patch contributed by Bill
3764 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003765
Georg Brandl3ee81df2008-05-17 18:14:43 +00003766- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003767 that the SMTP.starttls() caller no longer needs to call ehlo()
3768 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003769 does not claim to support starttls. Adds the
3770 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
3771 Fenner.

3851 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3852 silently miscode subclasses of those types. Now, it raises a
3853 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00003854

Georg Brandl3ee81df2008-05-17 18:14:43 +00003869 time so that opening a database previously created with the DB_DUP
3870 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3871 opens. Specifically: dictionary assignment to a DB object will
3872 replace all values for a given key when the database allows
3873 duplicate values. DB users should use DB.put(k, v) when they want
3874 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003875

3881 characters with ASCII value less than 32. Also, it correctly quotes
3882 dots only if they occur on a single line, as opposed to the previous
3883 behavior of quoting dots if they are the second character of any
3884 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003885
