13-----------------
14
Eric Smith9139cc62009-04-30 00:58:58 +000015- Issue #1588: Add complex.__format__. For example,
16 format(complex(1, 2./3), '.5') now produces a sensible result.
17
Mark Dickinson92fcc9c2009-04-29 20:41:00 +000018- Issue #5864: Fix empty format code formatting for floats so that it
19 never gives more than the requested number of significant digits.
20
Eric Smithcac7af62009-04-27 19:04:37 +000021- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes

31
Mark Dickinson95bc9802009-04-24 12:46:53 +000032- Issue #5816: complex(repr(z)) now recovers z exactly, even when
33 z involves nans, infs or negative zeros.
34
Eric Smithaca19e62009-04-22 13:29:05 +000035- Implement PEP 378, Format Specifier for Thousands Separator, for
36 floats, ints, and longs.
37
38- Issue #5515: 'n' formatting for ints, longs, and floats handles
39 leading zero formatting poorly.
40
41- Issue #5772: For float.__format__, don't add a trailing ".0" if
42 we're using no type code and we have an exponent.
43
Mark Dickinson6736cf82009-04-20 21:13:33 +000044- Issue #3166: Make long -> float (and int -> float) conversions
45 correctly rounded.
46

48 some builtin types.
49
Mark Dickinson1bdf7e92009-04-18 14:59:42 +000050- Issue #1869: fix a couple of minor round() issues. round(5e15+1)
Eric Smith9139cc62009-04-30 00:58:58 +000051 was giving 5e15+2; round(-0.0) was losing the sign of the zero.
Mark Dickinson1bdf7e92009-04-18 14:59:42 +000052
Benjamin Peterson99d36f12009-04-15 21:26:36 +000053- Issue #5759: float() didn't call __float__ on str subclasses.
54
Georg Brandl3c4a5462009-04-12 12:08:12 +000055- Issue #5704: the "-3" command-line option now implies "-t".

58 its clarity and its speed.
59
Antoine Pitrou789be0c2009-04-02 21:18:34 +000060- Issue #2396: the memoryview object was backported from Python 3.1.
61
Georg Brandld3f03fa2009-04-02 18:09:04 +000062- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"
63 when hitting the recursion limit under certain circumstances.
64

66
Ronald Oussorene0154ed2009-03-30 23:10:35 +000067- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
68 the end sys.path, for compatibility with the system install of Python.
69
Antoine Pitrouf8387af2009-03-23 18:41:45 +000070- Issue #4688: Add a heuristic so that tuples and dicts containing only
71 untrackable objects are not tracked by the garbage collector. This can
72 reduce the size of collections and therefore the garbage collection overhead
73 on long-running programs, depending on their particular use of datatypes.
74
Mark Dickinson0b666bf2009-03-23 18:25:13 +000075- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
76 improve its performance. Long divisions and remainder operations
77 are now between 50% and 150% faster.
78
Mark Dickinsonefc82f72009-03-20 15:51:55 +000079- Issue #4258: Make it possible to use base 2**30 instead of base
80 2**15 for the internal representation of integers, for performance
81 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
82 --enable-big-digits option to configure, which overrides the
83 default. Add sys.long_info structseq to provide information about
84 the internal format.
85
Benjamin Peterson6ffe8522009-03-18 20:52:15 +000086- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
87 result traceback.__members__ no longer exists.)
88
Mark Dickinson6b265f12009-03-18 16:07:26 +000089- Issue #4474: PyUnicode_FromWideChar now converts characters outside
90 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
91 and sizeof(Py_UNICODE) == 2.
92
Eric Smith6f42edb2009-03-14 11:57:26 +000093- Issue #5237: Allow auto-numbered fields in str.format(). For
94 example: '{} {}'.format(1, 2) == '1 2'.
95
Brett Cannon6c4cff02009-03-11 04:51:06 +000096- Issue #3652: Make the 'line' argument for warnings.showwarning() a
97 requirement. Means the DeprecationWarning from Python 2.6 can go away.
98
Eric Smithe9fb6862009-02-20 14:02:36 +000099- Issue #5247: Improve error message when unknown format codes are
100 used when using str.format() with str, unicode, long, int, and
101 float arguments.
102
Raymond Hettinger08259e82009-02-18 23:10:19 +0000103- Running Python with the -3 option now also warns about classic division
104 for ints and longs.
105
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000106- Issue #5260: Long integers now consume less memory: average
107 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
108 on a 64-bit system.
109
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000110- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
111 rotating the object pointer by 4 bits to the right.
112
Mark Dickinsonc97c9092009-02-09 14:18:43 +0000113- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
114 it now forces its argument to double before testing for infinity.
115
Benjamin Petersone18ef192009-01-20 14:21:16 +0000116- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
117
Georg Brandl29c6a282009-04-05 20:23:13 +0000118- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000119 were suppressing all exceptions. These include list(), filter(), map(),
120 zip(), and bytearray().
121
Benjamin Peterson596d3062009-01-19 15:42:23 +0000122- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
123 functions.
124
Benjamin Peterson5848d1f2009-01-19 00:08:08 +0000125- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an
126 OSError.
127
Amaury Forgeot d'Arca18392a2009-01-13 23:19:08 +0000128- Issue #4807: Port the _winreg module to Windows CE.
129
Antoine Pitrouc2f02212009-01-13 23:13:52 +0000130- Issue #4935: The overflow checking code in the expandtabs() method common
131 to str, bytes and bytearray could be optimized away by the compiler, letting
132 the interpreter segfault instead of raising an error.
133
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +0000134- Issue #3720: Fix a crash when an iterator modifies its class and removes its
135 __next__ method.
136
Martin v. Löwise3422fa2009-01-12 08:11:24 +0000137- Issue #4893: Use NT threading on CE.

140
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000141- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
142 collecting the oldest generation) so that allocating lots of objects without
143 destroying them does not show quadratic performance. Based on a proposal by
144 Martin von Löwis at
145 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
146
Martin v. Löwisb90304a2009-01-07 18:40:40 +0000147- Issue #4850: Change COUNT_ALLOCS variables to Py_ssize_t.
148
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000149- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
150 an existing .py counterpart, override the co_filename attributes of all
151 code objects if the original filename is obsolete (which can happen if the
152 file has been renamed, moved, or if it is accessed through different paths).
153 Patch by Ziga Seilnacht and Jean-Paul Calderone.
154
Martin v. Löwis5344c992009-01-02 20:32:55 +0000155- Issue #4075: Use OutputDebugStringW in Py_FatalError.
156
Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +0000157- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
158 file with `str' filename on Windows.
159
Antoine Pitrouaa687902009-01-01 14:11:22 +0000160- Issue #3680: Reference cycles created through a dict, set or deque iterator
161 did not get collected.
162
Nick Coghlan180e4002008-12-30 01:18:48 +0000163- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
164 where the tp_hash and tp_dict slots are both NULL.
165
Benjamin Peterson7af65562008-12-29 17:56:58 +0000166- Issue #4764: With io.open, IOError.filename is set when trying to open a
167 directory on POSIX systems.
168
Benjamin Petersonfe231b02008-12-29 17:47:42 +0000169- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
170 systems.
171
Georg Brandl6425a2f2008-12-28 11:54:53 +0000172- Issue #4759: None is now allowed as the first argument of
173 bytearray.translate(). It was always allowed for bytes.translate().
174
Skip Montanarof205c132008-12-23 03:30:15 +0000175- Added test case to ensure attempts to read from a file opened for writing
176 fail.
177
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000178- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
179 print elapsed times, not only when some objects are uncollectable /
180 unreachable. Original patch by Neil Schemenauer.
181
Mark Dickinson1a707982008-12-17 16:14:37 +0000182- Issue #3439: Add a bit_length method to int and long.
183
Antoine Pitroud0c35152008-12-17 00:38:28 +0000184- Issue #2183: Simplify and optimize bytecode for list comprehensions.
185 Original patch by Neal Norwitz.
186

188 context manager returns a value that cannot be converted to a bool.
189
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000190- Issue #4597: Fixed several opcodes that weren't always propagating
191 exceptions.
192
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000193- Issue #4445: Replace "sizeof(PyStringObject)" with
194 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
195 str instances. On a typical machine this saves 3 bytes of memory
196 (on average) per string allocation.
197
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000198- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
199 interpreter to abort ("Fatal Python error: Could not reset the stack!")
200 instead of throwing a MemoryError.

207
Vinay Sajip213faca2008-12-03 23:22:58 +0000208- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000209 method on file objects with closefd=False. The file descriptor is still
210 kept open but the file object behaves like a closed file. The ``FileIO``
211 object also got a new readonly attribute ``closefd``.
212
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000213- Issue #4348: Some bytearray methods returned that didn't cause any change to
214 the bytearray, returned the same bytearray instead of a copy.
215
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000216- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.

221
Benjamin Petersondcee09d2008-10-31 02:16:05 +0000222- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
223 exec statement.
224
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000225- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
226 method does not return iterators for the 4th and 5th items.
227
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000228- Issue #4209: Enabling unicode_literals and the print_function in the same
229 __future__ import didn't work.
230
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000231- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000232 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000233
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000234- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
235 returned a path longer than MAX_PATH. (But It's doubtful this code path is
236 really executed because I cannot move to such directory on win2k)
237
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000238- Issue #4069: When set.remove(element) is used with a set element, the element
239 is temporarily replaced with an equivalent frozenset. But the eventual
240 KeyError would always report the empty frozenset([]) as the missing key. Now
241 it correctly refers to the initial element.
242
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000243- Issue #4509: Various issues surrounding resize of bytearray objects to
244 which there are buffer exports.
245
Benjamin Peterson8d5934b2008-12-27 18:24:11 +0000246- Issue #4748: Lambda generators no longer return a value.
247

253 short file names.
254
Matthias Klose91a3b9e2009-04-05 21:19:13 +0000255- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
256 to avoid compiler warnings.
Matthias Klose0610e082009-04-05 12:43:08 +0000257
Gregory P. Smith2b3eb372009-04-05 23:48:26 +0000258- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
259 returned them on 64bit platforms.
260
Walter Dörwalded960ac2009-05-03 22:36:33 +0000261- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
262 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
263 step. This avoids problems with counting UTF-8 bytes that ignores the effect
264 of using the replace error handler in PyUnicode_DecodeUTF8().

Georg Brandl29c6a282009-04-05 20:23:13 +0000593- Issue #5021: doctest.testfile() did not create __name__ and
Raymond Hettingerecf252a2009-01-27 10:03:04 +0000594 collections.namedtuple() relied on __name__ being defined.
595
Brett Cannon93881c62009-01-26 01:16:50 +0000596- Backport importlib from Python 3.1. Only the import_module() function has

628 do an explicit seek to the end of file (so that e.g. tell() returns the
629 file size rather than 0). This is consistent with the behaviour of the

1043
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001044- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1045 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1046 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1047 ``printf`` function, whereas PyString_FromFormat has an independent
1048 implementation and uses "%zd" on all platforms for size_t values.
1049 This makes a difference on win64, where ``printf`` needs "%Id" to display
1050 64bit values.

Vinay Sajip35e3b032008-09-01 14:33:59 +00001069- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001070 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1071 mechanism. In the process, fix a bug where isinstance() and issubclass(),

1073 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1074 type object.

Jesse Noller438195f2009-01-18 21:04:36 +00001169- Issue #4301: Patch the logging module to add processName support, remove
1170 _check_logger_class from multiprocessing.
1171
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001172- Issue #2975: When compiling several extension modules with Visual Studio 2008
1173 from the same python interpreter, some environment variables would grow
1174 without limit.
1175
Benjamin Peterson37346b22008-08-23 20:27:43 +00001176- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

1192 wrapper for warnings.catch_warnings() that makes it easier to check
1193 that expected warning messages are being reported.
1194

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001213What's New in Python 2.6 beta 3?
1214================================
1215
Barry Warsaw07a4a382008-08-21 01:15:08 +00001216*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001217
1218Core and Builtins
1219-----------------
1220
Guido van Rossumf8402962008-08-20 15:01:50 +00001221- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1222 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1223 extensions do not automatically benefit from the class attribute
1224 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1225 to their tp_flags field if they care. This is a backwards
1226 compatibility feature; in 3.0, all types will use the cache by
1227 default.
1228
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001229- Keyword arguments can now follow starred arguments. (``f(a, *args,
1230 keyword=23)`` is now valid syntax.)
1231
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001232- ctypes function pointers that are COM methods have a boolean True
1233 value again.
1234
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001235- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1236 by denying s# to parse objects that have a releasebuffer procedure,
1237 and introducing s*.
1238
Georg Brandl1e13ea92008-08-11 09:07:59 +00001239- Issue #3537: Fix an assertion failure when an empty but presized dict
1240 object was stored in the freelist.
1241
Mark Dickinsonb6467572008-08-04 21:30:09 +00001242- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1243 ValueError consistently across platforms.
1244
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001245- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1246 (64bit Unix, for example), unichr() would truncate its argument and return
1247 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1248
Neal Norwitze7d8be82008-07-31 17:17:14 +00001249- Apply security patches from Apple.
1250
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001251- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1252 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1253
Antoine Pitrou92f82162008-07-25 22:22:08 +00001254- Issue #1819: function calls with several named parameters are now on
1255 average 35% faster (as measured by pybench).
1256
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001257- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1258 the python debugger steps into a class statement: the free variables (local
1259 variables defined in an outer scope) would be deleted from the outer scope.
1260
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001261- Issue #2620: Overflow checking when allocating or reallocating memory
1262 was not always being done properly in some python types and extension
1263 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1264 all been updated to perform better checks and places in the code that
1265 would previously leak memory on the error path when such an allocation
1266 failed have been fixed.
1267
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001268Library
1269-------
1270
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001271- Issue #3612: Added some missing basic types in ctypes.wintypes.
1272
Benjamin Petersone977ad42008-08-20 01:42:01 +00001273- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1274 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1275
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001276- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1277 version reported by these tools does not necessarily follow the python
1278 version numbering scheme, so the module is less strict when parsing it.
1279
Nick Coghlanf70385a2008-08-18 12:42:46 +00001280- Issue #2235: Added Py3k warnings for types which will become unhashable
1281 under the stricter __hash__ inheritance rules in 3.0. Several types
1282 which did not meet the rules for hash invariants and were already
1283 unhashable in 3.0 have now been explicitly flagged as unhashable in
1284 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1285 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1286
Brett Cannon88f801d2008-08-18 00:46:22 +00001287- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1288 imported into the module but exposed as part of the module's API.
1289
Brett Cannon7b96f072008-08-18 00:41:11 +00001290- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1291
Brett Cannon46225e72008-08-18 00:36:52 +00001292- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
1293
Brett Cannon25c9d6a2008-08-17 22:10:11 +00001294- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1295
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001296- Issue #3575: Incremental decoder's decode function now takes bytearray
1297 by using 's*' instead of 't#'.
1298
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00001299- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001300 fails unicode conversion on 2nd parameter. (windows only)
1301
Facundo Batista94f243a2008-08-17 03:38:39 +00001302- Issue 2464. urllib2 now supports a malformation in the URL received
1303 in a redirect.
1304
Brett Cannonabe423e2008-08-16 21:47:07 +00001305- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001306 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001307
Facundo Batistaeb90b782008-08-16 14:44:07 +00001308- Issue #2776: fixed small issue when handling an URL with double slash
1309 after a 302 response in the case of not going through a proxy.
1310
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001311- Issue #2676: in the email package, content-type parsing was hanging on
1312 pathological input because of quadratic or exponential behaviour of a
1313 regular expression.
1314
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001315- Issue #3476: binary buffered reading through the new "io" library is now
1316 thread-safe.
1317
Brett Cannonbf3157b2008-08-14 05:00:03 +00001318- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1319 since mimetools itself is deprecated. Because modules are cached, all
1320 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1321
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001322- Issue #3134: shutil referenced undefined WindowsError symbol.
1323
Robert Schuppenies14646332008-08-10 11:01:53 +00001324- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1325 menu entries were not deleted.
1326
Brett Cannon83e81842008-08-09 23:30:55 +00001327- Copied the implementation of reduce() to _functools.reduce() to have a
1328 version that did not raise a DeprecationWarning under -3.
1329
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001330- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1331 a MemoryError rather than silently stop the iteration.
1332
Guido van Rossum59ce9012008-08-09 14:55:34 +00001333- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1334 to _sre.compile() will now be rejected. This should not affect anybody
1335 since the re.compile() function never generates invalid re-bytecode.
1336
Skip Montanaroa032bf42008-08-08 22:52:51 +00001337- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1338 upon first access it can be automatically initialized from the csv file if
1339 it wasn't initialized during instantiation.
1340
Brett Cannon3aa2a492008-08-06 22:28:09 +00001341- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1342 the reload() built-in has been removed.
1343
Brett Cannon7e30b672008-08-04 21:52:25 +00001344- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001345 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

1348 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
1349 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
1350 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00001351
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00001352- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
1353 raised an AttributeError.
1354
Benjamin Peterson01a24322008-07-28 23:35:27 +00001355- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001356 asking for a specific length. This problem only affected files opened
1357 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001358
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00001359- Issue #3449: Update decimal module to use most recent specification
1360 (v. 1.68) and tests (v. 2.58) from IBM.
1361
Skip Montanarof9ac43f2008-07-27 00:50:41 +00001362- Issue 3437: Bug fix in robotparser parsing of Allow: lines.
1363
Raymond Hettinger8c664e82008-07-25 18:43:33 +00001364- Issue 1592: Improve error reporting when operations are attempted
1365 on a closed shelf.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001369- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
1370
1371- Issue #3303: Fix a crash in locale.strcoll() when calling it with
1372 invalid arguments.
1373
1374- Issue #3302: Fix several crashes when calling locale's gettext functions
1375 with None arguments.
1376
1377- Issue #3389: Allow resolving dotted names for handlers in logging
1378 configuration files.
1379
1380- Deprecate the sunaudio module for removal in Python 3.0.
1381
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001382- Issue #3394: zipfile.writestr sets external attributes when passed a
1383 file name rather than a ZipInfo instance, so files are extracted with
1384 mode 0600 rather than 000 under Unix.
1385
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001386- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1387 argument in python 2.5, this broke code that subclassed Popen to include its
1388 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00001398- Issue #2235: the C API function PyObject_HashNotImplemented and its
1399 interaction with the tp_hash slot (added in 2.6b2) are now documented
1400
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001401- Issue #643841: The language reference now provides more detailed
1402 coverage of the lookup process for special methods. The disclaimers
1403 regarding lack of coverage of new-style classes have also been
1404 removed, since the coverage is now fairly reasonable.

1409
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001410*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001412Core and Builtins
1413-----------------
1414
Georg Brandl3e483f62008-07-16 22:57:41 +00001415- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1416 its methods now allow for items objects that can be converted to
1417 an integer using operator.index().
1418
Mark Dickinson64b7e502008-07-16 09:40:03 +00001419- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1420 produced a ValueError instead of giving the correct float.
1421
Eric Smitha5fa5a22008-07-16 00:11:49 +00001422- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1423 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1424
Mark Dickinson7103aa42008-07-15 19:08:33 +00001425- Issue #3008: the float type has a new instance method 'float.hex'
1426 and a new class method 'float.fromhex' to convert floating-point
1427 numbers to and from hexadecimal strings, respectively.
1428
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001429- Issue #2235: __hash__ is once again inherited by default. To allow
1430 collections.Hashable to remain meaningful in the presence of the
1431 default hash implementation (object.__hash__), it is now possible
1432 to explicit block inheritance of hash by setting __hash__=None at
1433 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1434 level.
1435
Nick Coghlanb028f502008-07-13 14:52:36 +00001436- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1437 the parent module cannot be found while performing an absolute import.
1438 This means that an incorrectly defined __package__ attribute will
1439 now only prevent relative imports in that module rather than causing
1440 all imports from that module to fail.
1441
Nick Coghlan14ff9942008-07-08 14:21:42 +00001442- Issue #2517: Allow unicode messages in Exceptions again by correctly
1443 bypassing the instance dictionary when looking up __unicode__ on
1444 new-style classes.
1445
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001446- Issue #3242: Fix a crash inside the print statement, if sys.stdout is

1452 another thread's dictionary.
1453
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001454- Issue #3004: Minor change to slice.indices(): the start and stop
1455 arguments are now treated identically, making the behaviour easier
1456 to describe and understand. For example, slice(None, -10,
1457 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1458 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,

Georg Brandl5cc774e2008-06-11 20:28:06 +00001913 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001914
1915 This is controlled by the configure argument ``--with-universal-archs``:
1916
1917 - ``--with-universal-archs=all``: install 4-way universal
1918
1919 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
1920
1921 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit

Georg Brandl3ee81df2008-05-17 18:14:43 +00001975- Issue #1631171: Re-implement the 'warnings' module in C (the
1976 original Python code has been kept as backup). This will allow for
1977 using the 'warning's machinery in such places as the parser where
1978 use of pure Python code is not possible. Both the ``showarning()``
1979 and ``formatwarning()`` gain an optional 'line' argument which is
1980 not called by default for backwards-compatibility reasons. Setting
1981 ``warnings.showwarning()`` to an implementation that lacks support
1982 for the ``line`` argument will raise a DeprecationWarning.

2006
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002007- The getpass module has been improved on Unix. It now uses /dev/tty

Georg Brandl3ee81df2008-05-17 18:14:43 +00002045- Issue #2550: The approach used by client/server code for obtaining
2046 ports to listen on in network-oriented tests has been refined in an
2047 effort to facilitate running multiple instances of the entire
2048 regression test suite in parallel without issue.
2049 test_support.bind_port() has been fixed such that it will always
2050 return a unique port -- which wasn't always the case with the
2051 previous implementation, especially if socket options had been set
2052 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2053 new implementation of bind_port() will actually raise an exception
2054 if it is passed an AF_INET/SOCK_STREAM socket with either the
2055 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2056 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2057 the socket it's been passed. This currently only applies to
2058 Windows. This option prevents any other sockets from binding to the
2059 host/port we've bound to, thus removing the possibility of the
2060 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2061 when a second SOCK_STREAM socket binds and accepts to a host/port
2062 that's already been bound by another socket. The optional preferred
2063 port parameter to bind_port() has been removed. Under no
2064 circumstances should tests be hard coding ports!
2065
2066 test_support.find_unused_port() has also been introduced, which will
2067 pass a temporary socket object to bind_port() in order to obtain an
2068 unused port. The temporary socket object is then closed and
2069 deleted, and the port is returned. This method should only be used
2070 for obtaining an unused port in order to pass to an external program
2071 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2072 a parameter to a server-oriented class that doesn't give you direct
2073 access to the underlying socket used.
2074
2075 Finally, test_support.HOST has been introduced, which should be used
2076 for the host argument of any relevant socket calls (i.e. bind and
2077 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002078
2079 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002080 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002081 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2082 test_asynchat and test_socket_ssl.
2083
Georg Brandl3ee81df2008-05-17 18:14:43 +00002084 It is now possible for multiple instances of the regression test
2085 suite to run in parallel without issue.

2353
Fred Drakea8ee94b2008-03-01 02:45:07 +00002354- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002355 644. The mode is now inherited from the py file.

2358
2359- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002360
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002361- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002362 issue 215555 for a discussion.
2363
Eric Smitha73fbe72008-02-23 03:09:44 +00002364- Added the future_builtins module, which contains hex() and oct().
2365 These are the PEP 3127 version of these functions, designed to be
2366 compatible with the hex() and oct() builtins from Python 3.0. They
2367 differ slightly in their output formats from the existing, unchanged
2368 Python 2.6 builtins. The expected usage of the future_builtins
2369 module is:
2370 from future_builtins import hex, oct
2371
Eric Smith7ef40bf2008-02-20 23:34:22 +00002372- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2373 exponents for exponents with absolute value < 100. Follows C99
2374 standard. This is a change on Windows, which would use 3 digits.
2375 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2376 so that any alterations it does to the resulting string will be
2377 available in stringlib/formatter.h (for float.__format__).
2378
Eric Smith5a3c1352008-02-19 13:21:56 +00002379- Implemented PEP 3101, Advanced String Formatting. This adds a new
2380 builtin format(); a format() method for str and unicode; a
2381 __format__() method to object, str, unicode, int, long, float, and
2382 datetime; the class string.Formatter; and the C API
2383 PyObject_Format().
2384
Georg Brandl3ee81df2008-05-17 18:14:43 +00002385- Fixed several potential crashes, all caused by specially crafted
2386 __del__ methods exploiting objects in temporarily inconsistent
2387 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002388
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002389- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002390 prevent a possible crash: an Abstract Base Class would try to access
2391 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002392
Georg Brandl3ee81df2008-05-17 18:14:43 +00002393- Fixed repr() and str() of complex numbers with infinity or nan as
2394 real or imaginary part.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002396- Clear all free lists during a gc.collect() of the highest generation
2397 in order to allow pymalloc to free more arenas. Python may give back
2398 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002399
Georg Brandl3ee81df2008-05-17 18:14:43 +00002400- Issue #2045: Fix an infinite recursion triggered when printing a
2401 subclass of collections.defaultdict, if its default_factory is set
2402 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002403
Christian Heimesf75dbef2008-02-08 00:11:31 +00002404- Fixed a minor memory leak in dictobject.c. The content of the free
2405 list was not freed on interpreter shutdown.
2406
Georg Brandl3ee81df2008-05-17 18:14:43 +00002407- Limit free list of method and builtin function objects to 256
2408 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002409
Georg Brandl3ee81df2008-05-17 18:14:43 +00002410- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2411 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002412 to compact the internal free lists of pre-allocted ints and floats.
2413
Georg Brandl3ee81df2008-05-17 18:14:43 +00002414- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2415 calls. Python expected the return type int but the fork familie
2416 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002417
Georg Brandl3ee81df2008-05-17 18:14:43 +00002418- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2419 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002420
Georg Brandl3ee81df2008-05-17 18:14:43 +00002421- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2422 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002423
Georg Brandl3ee81df2008-05-17 18:14:43 +00002424- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2425 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00002427- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2428 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002429
Georg Brandl3ee81df2008-05-17 18:14:43 +00002430- Patch #1473257: generator objects gain a gi_code attribute. This is
2431 the same object as the func_code attribute of the function that
2432 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002433
Georg Brandl3ee81df2008-05-17 18:14:43 +00002434- Issue #1920: "while 0" statements were completely removed by the
2435 compiler, even in the presence of an "else" clause, which is
2436 supposed to be run when the condition is false. Now the compiler
2437 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002438
Guido van Rossumeead05f2008-01-24 18:21:02 +00002439- A few crashers fixed: weakref_in_del.py (issue #1377858);
2440 loosing_dict_ref.py (issue #1303614, test67.py);
2441 borrowed_ref_[34].py (not in tracker).
2442
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002443- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002444 suppressed while an extension is loaded by calling SetErrorMode in
2445 dynload_win.c. The error is still reported properly.
2446
Georg Brandl3ee81df2008-05-17 18:14:43 +00002447- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002448 several extension methods and modules do not work without unicode
2449 support.
2450
Georg Brandl26543b12008-01-21 18:36:51 +00002451- Issue #1882: when compiling code from a string, encoding cookies in the
2452 second line of code were not always recognized correctly.
2453
Georg Brandl14404b62008-01-19 19:27:05 +00002454- Issue #1679: "0x" was taken as a valid integer literal.
2455
Georg Brandl6caad7d2008-01-26 14:19:22 +00002456- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002457 added.
2458
Christian Heimesc94e2b52008-01-14 04:13:37 +00002459- sys.float_info / PyFloat_GetInfo: The floating point information
2460 object was converted from a dict to a specialized structseq object.
2461
Georg Brandl3ee81df2008-05-17 18:14:43 +00002462- Patch #1816: Added sys.flags structseq. It exposes the status of
2463 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002464
Georg Brandl3ee81df2008-05-17 18:14:43 +00002465- Objects/structseq.c: Implemented new structseq representation. The
2466 patch makes structseqs (e.g. the return value of os.stat) more
2467 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002468
Georg Brandl3ee81df2008-05-17 18:14:43 +00002469- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00002481- Improve some exception messages when Windows fails to load an
2482 extension module. Now we get for example '%1 is not a valid Win32
2483 application' instead of 'error code 193'.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002491 and INF. float("nan"), float("inf") and float("-inf") now work on
2492 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002493
Georg Brandl3ee81df2008-05-17 18:14:43 +00002494- Compiler now generates simpler and faster code for dictionary
2495 literals. The oparg for BUILD_MAP now indicates an estimated
2496 dictionary size. There is a new opcode, STORE_MAP, for adding
2497 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002526- Patch #1739468: Directories and zipfiles containing a __main__.py
2527 file can now be directly executed by passing their name to the
2528 interpreter. The directory/zipfile is automatically inserted as the
2529 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002530
Georg Brandl3ee81df2008-05-17 18:14:43 +00002531- Issue #1265: Fix a problem with sys.settrace, if the tracing
2532 function uses a generator expression when at the same time the
2533 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002534
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002535- sets and frozensets now have an isdisjoint() method.

2540
Georg Brandl3ee81df2008-05-17 18:14:43 +00002541- The enumerate() builtin function is no longer bounded to sequences
2542 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2543 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002544
Georg Brandl3ee81df2008-05-17 18:14:43 +00002545- Issue #1686386: Tuple's tp_repr did not take into account the
2546 possibility of having a self-referential tuple, which is possible
2547 from C code. Nor did object's tp_str consider that a type's tp_str
2548 could do something that could lead to an inifinite recursion.
2549 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2550 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002551
Georg Brandl3ee81df2008-05-17 18:14:43 +00002552- Issue #1164: It was possible to trigger deadlock when using the
2553 'print' statement to write to a file since the GIL was not released
2554 as needed. Now PyObject_Print() does the right thing along with
2555 various tp_print implementations of the built-in types and those in
2556 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002557
Georg Brandl3ee81df2008-05-17 18:14:43 +00002558- Issue #1147: Exceptions were directly allowing string exceptions in
2559 their throw() method even though string exceptions no longer
2560 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002561
Georg Brandl3ee81df2008-05-17 18:14:43 +00002562- Issue #1096: Prevent a segfault from getting the repr of a very
2563 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002564
Brett Cannon1e534b52007-09-07 04:18:30 +00002565- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002566 PyObject_Call() never calling back out to Python code to trigger
2567 recursion depth updates/checks. Required the creation of a static
2568 RuntimeError instance in case normalizing an exception put the
2569 recursion check value past its limit. Fixes crashers
2570 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002571

Neal Norwitz0ac60192007-05-27 04:08:54 +00002585- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002586 __*__ attributes. (Some already existed, e.g., __doc__ and
2587 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002588
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002589- Add -3 option to the interpreter to warn about features that are
2590 deprecated and will be changed/removed in Python 3.0.
2591
Georg Brandl2134e752007-05-21 20:34:16 +00002592- Patch #1686487: you can now pass any mapping after '**' in function
2593 calls.
2594
Collin Winter62903052007-05-18 23:11:24 +00002595- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002596 "except E as target:". This is to provide forwards compatibility
2597 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002598
Brett Cannon229cee22007-05-05 01:34:02 +00002599- Deprecate BaseException.message as per PEP 352.
2600
Georg Brandl3ee81df2008-05-17 18:14:43 +00002601- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002602 inherited from a builtin base.
2603
Vinay Sajip8549ce32007-05-06 17:53:37 +00002604- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002605 setting a plain string, ie don't expand to single letter identifiers.
2606
Raymond Hettinger13936692007-04-11 18:40:58 +00002607- Request #1191699: Slices can now be pickled.
2608
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002609- Request #1193128: str.translate() now allows a None argument for
2610 translations that only remove characters without re-mapping the
2611 remaining characters.
2612
Georg Brandl5cb76c12007-03-21 09:00:39 +00002613- Patch #1682205: a TypeError while unpacking an iterable is no longer
2614 masked by a generic one with the message "unpack non-sequence".
2615
Neal Norwitzaa754b72007-03-21 06:39:48 +00002616- Remove unused file Python/fmod.c.
2617
Guido van Rossum143b5642007-03-23 04:58:42 +00002618- Bug #1683368: The object.__init__() and object.__new__() methods are
2619 now stricter in rejecting excess arguments. The only time when
2620 either allows excess arguments is when it is not overridden and the
2621 other one is. For backwards compatibility, when both are
2622 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002623 warning later). Also, type.__init__() insists on the same signature
2624 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002625
Georg Brandl3ee81df2008-05-17 18:14:43 +00002626- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2627 object to complex using its __complex__() method before falling back
2628 to the __float__() method. Therefore, the functions in the cmath
2629 module now can operate on objects that define a __complex__()
2630 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002631
Georg Brandl3ee81df2008-05-17 18:14:43 +00002632- Patch #1623563: allow __class__ assignment for classes with
2633 __slots__. The old and the new class are still required to have the
2634 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00002635

2640 ``object.__reduce_ex__()`` is called with an object that is faking
2641 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002642
Georg Brandl3ee81df2008-05-17 18:14:43 +00002643- Patch #1680015: Don't modify __slots__ tuple if it contains an

2647
Georg Brandl7b9c5552007-03-12 14:30:05 +00002648- Bug #1678647: write a newline after printing an exception in any
2649 case, even when converting the value to a string failed.
2650
Georg Brandl871f1bc2007-03-12 13:17:36 +00002651- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002652 its argument, if it exists. If not, it will work like before. This
2653 allows customizing the output of dir() in the presence of a
2654 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002655
Collin Winter276887b2007-03-12 16:11:39 +00002656- Patch #922167: Python no longer segfaults when faced with infinitely
2657 self-recursive reload() calls (as reported by bug #742342).
2658

Georg Brandl3ee81df2008-05-17 18:14:43 +00002662- Patch #1491866: change the complex() constructor to allow
2663 parthensized forms. This means complex(repr(x)) now works instead of
2664 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002665
Georg Brandlaa2321b2007-03-07 00:40:28 +00002666- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002667 makes the filenames the warning module prints much more sensible
2668 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002669
Georg Brandl49aafc92007-03-07 00:34:46 +00002670- Variant of patch #697613: don't exit the interpreter on a SystemExit
2671 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00002672 variable is given, but break into the interactive interpreter just
2673 like on other exceptions or normal program exit.

Georg Brandl098cd692007-03-06 12:17:50 +00002680
Georg Brandl0fca97a2007-03-05 22:28:08 +00002681- Patch #1674228: when assigning a slice (old-style), check for the
2682 sq_ass_slice instead of the sq_slice slot.
2683
Georg Brandl3ee81df2008-05-17 18:14:43 +00002684- When printing an unraisable error, don't print exceptions. before
2685 the name. This duplicates the behavior whening normally printing
2686 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00002687
Georg Brandl3ee81df2008-05-17 18:14:43 +00002688- Bug #1653736: Properly discard third argument to

2743
Armin Rigo7ccbca92006-10-04 12:17:45 +00002744- A number of places, including integer negation and absolute value,

3311 TestCase and TestSuite subclasses (not instances) are no longer
3312 accepted in TestSuite.addTest(). This should cause no

3314 -- the failure just occurred later, with a more cumbersome
3315 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003596- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3597 with RFC 3207 and forgets any knowledge obtained from the server not
3598 obtained from the TLS negotiation itself. Patch contributed by Bill
3599 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003600
Georg Brandl3ee81df2008-05-17 18:14:43 +00003601- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003602 that the SMTP.starttls() caller no longer needs to call ehlo()
3603 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003604 does not claim to support starttls. Adds the
3605 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

3686 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3687 silently miscode subclasses of those types. Now, it raises a

Raymond Hettinger12e94202007-11-07 01:13:09 +00003689

Georg Brandl3ee81df2008-05-17 18:14:43 +00003704 time so that opening a database previously created with the DB_DUP
3705 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3706 opens. Specifically: dictionary assignment to a DB object will
3707 replace all values for a given key when the database allows
3708 duplicate values. DB users should use DB.put(k, v) when they want
3709 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003710

3716 characters with ASCII value less than 32. Also, it correctly quotes
3717 dots only if they occur on a single line, as opposed to the previous
3718 behavior of quoting dots if they are the second character of any
3719 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003720

4042-----
4043
Georg Brandl3ee81df2008-05-17 18:14:43 +00004044- Unified naming convention for free lists and their limits. All free
4045 lists in Object/ are named ``free_list``, the counter ``numfree``
4046 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
4047 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004048
Georg Brandl3ee81df2008-05-17 18:14:43 +00004049- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4050 to ``PyTuple_SetItem``, it can be used to populate a brand new
4051 frozenset; but it does not steal a reference to the added item.

4063
Georg Brandl3ee81df2008-05-17 18:14:43 +00004064- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4065 of w# format code incorrectly truncated the length to an int, even
4066 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4067 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004068
Georg Brandl3ee81df2008-05-17 18:14:43 +00004069- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

4087- Fix some leftovers from the conversion from int to Py_ssize_t
4088 (relevant to strings and sequences of more than 2**31 items).
4089
4090- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4091 outside of pystate.c and should not be necessary.
4092
Georg Brandl3ee81df2008-05-17 18:14:43 +00004093- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4094 absolute imports. In earlier versions they might have used relative
4095 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004096
Georg Brandl3ee81df2008-05-17 18:14:43 +00004097- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4098 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004099
Georg Brandl3ee81df2008-05-17 18:14:43 +00004100- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00004107- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
4108 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
4109 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
4110 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00004111

Georg Brandl3ee81df2008-05-17 18:14:43 +00004125- Removed the macfs module. It had been deprecated since Python 2.5.
4126 This lead to the deprecation of macostools.touched() as it relied
4127 solely on macfs and was a no-op under OS X.
