Barry Warsaw12582c92008-10-02 03:33:51 +00007What's New in Python 2.7 alpha 1
8================================

10*Release date: XX-XXX-20XX*
11
12Core and Builtins
13-----------------
14
Mark Dickinsona4e0efa2009-05-20 18:43:07 +000015- Issue #5829: complex("1e500") no longer raises OverflowError. This
16 makes it consistent with float("1e500") and interpretation of real
17 and imaginary literals.
18
Hirokazu Yamamotoa4f90182009-05-17 02:58:36 +000019- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.
20
Benjamin Peterson0c3b4c62009-05-16 23:34:19 +000021- __instancecheck__ and __subclasscheck__ are now completely ignored on classic
22 classes and instances.
Benjamin Petersoneb9fb2c2009-05-16 22:46:11 +000023
R. David Murray525cffc2009-05-13 13:07:14 +000024- Issue #5994: the marshal module now has docstrings.
25
Mark Dickinsonb1d45852009-05-11 15:33:08 +000026- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
27 (1) inf and nan strings with trailing whitespace were incorrectly
28 rejected; (2) parsing of strings representing infinities and nans
29 was locale aware; and (3) the interpretation of fromhex('-nan')
30 didn't match that of float('-nan').
31
Eric Smitha985a3a2009-05-05 18:26:08 +000032- Issue #5920: For float.__format__, change the behavior with the
33 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
34 to be like 'g' but with at least one decimal point and with a
35 default precision of 12. Previously, the behavior the same but with
36 a default precision of 6. This more closely matches str(), and
37 reduces surprises when adding alignment flags to the empty
38 presentation type. This also affects the new complex.__format__ in
39 the same way.
40
R. David Murray7ba8e1c2009-05-04 22:16:24 +000041- Issue #5890: in subclasses of 'property' the __doc__ attribute was
42 shadowed by classtype's, even if it was None. property now
43 inserts the __doc__ into the subclass instance __dict__.
44
Antoine Pitrou653dece2009-05-04 18:32:32 +000045- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
46 sequences. Patch by Nick Barnes and Victor Stinner.
47
Vinay Sajipf9b01fe2009-05-09 12:07:17 +000048- Issue #1588: Add complex.__format__. For example,
Eric Smith9139cc62009-04-30 00:58:58 +000049 format(complex(1, 2./3), '.5') now produces a sensible result.
50
Mark Dickinson92fcc9c2009-04-29 20:41:00 +000051- Issue #5864: Fix empty format code formatting for floats so that it
52 never gives more than the requested number of significant digits.
53
Eric Smithcac7af62009-04-27 19:04:37 +000054- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
55 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
56
Martin v. Löwis99f27792009-04-26 00:53:18 +000057- Issue #4971: Fix titlecase for characters that are their own
58 titlecase, but not their own uppercase.
59
Eric Smith068f0652009-04-25 21:40:15 +000060- Issue #5835: Deprecate PyOS_ascii_formatd and replace it with
61 _PyOS_double_to_string or PyOS_double_to_string.
62
Benjamin Peterson5083dc52009-04-25 00:41:22 +000063- Issue #5283: Setting __class__ in __del__ caused a segfault.
64
Mark Dickinson95bc9802009-04-24 12:46:53 +000065- Issue #5816: complex(repr(z)) now recovers z exactly, even when
66 z involves nans, infs or negative zeros.
67
Eric Smithaca19e62009-04-22 13:29:05 +000068- Implement PEP 378, Format Specifier for Thousands Separator, for
69 floats, ints, and longs.
70
71- Issue #5515: 'n' formatting for ints, longs, and floats handles
72 leading zero formatting poorly.
73
74- Issue #5772: For float.__format__, don't add a trailing ".0" if
75 we're using no type code and we have an exponent.
76
Mark Dickinson6736cf82009-04-20 21:13:33 +000077- Issue #3166: Make long -> float (and int -> float) conversions
78 correctly rounded.
79
Benjamin Petersond4d400c2009-04-18 20:12:47 +000080- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
81 some builtin types.
82
Mark Dickinson1bdf7e92009-04-18 14:59:42 +000083- Issue #1869: fix a couple of minor round() issues. round(5e15+1)
Eric Smith9139cc62009-04-30 00:58:58 +000084 was giving 5e15+2; round(-0.0) was losing the sign of the zero.
Mark Dickinson1bdf7e92009-04-18 14:59:42 +000085
Benjamin Peterson99d36f12009-04-15 21:26:36 +000086- Issue #5759: float() didn't call __float__ on str subclasses.
87
Georg Brandl3c4a5462009-04-12 12:08:12 +000088- Issue #5704: the "-3" command-line option now implies "-t".
89
R. David Murray0374a822009-04-09 21:54:50 +000090- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
91 its clarity and its speed.
92
Antoine Pitrou789be0c2009-04-02 21:18:34 +000093- Issue #2396: the memoryview object was backported from Python 3.1.
94
Georg Brandld3f03fa2009-04-02 18:09:04 +000095- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"
96 when hitting the recursion limit under certain circumstances.
97
Brett Cannon15ba4da2009-04-01 18:03:59 +000098- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
99
Ronald Oussorene0154ed2009-03-30 23:10:35 +0000100- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
101 the end sys.path, for compatibility with the system install of Python.
102
Antoine Pitrouf8387af2009-03-23 18:41:45 +0000103- Issue #4688: Add a heuristic so that tuples and dicts containing only
104 untrackable objects are not tracked by the garbage collector. This can
105 reduce the size of collections and therefore the garbage collection overhead
106 on long-running programs, depending on their particular use of datatypes.
107
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000108- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
109 improve its performance. Long divisions and remainder operations
110 are now between 50% and 150% faster.
111
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000112- Issue #4258: Make it possible to use base 2**30 instead of base
113 2**15 for the internal representation of integers, for performance
114 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
115 --enable-big-digits option to configure, which overrides the
116 default. Add sys.long_info structseq to provide information about
117 the internal format.
118
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000119- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
120 result traceback.__members__ no longer exists.)
121
Mark Dickinson6b265f12009-03-18 16:07:26 +0000122- Issue #4474: PyUnicode_FromWideChar now converts characters outside
123 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
124 and sizeof(Py_UNICODE) == 2.
125
Eric Smith6f42edb2009-03-14 11:57:26 +0000126- Issue #5237: Allow auto-numbered fields in str.format(). For
127 example: '{} {}'.format(1, 2) == '1 2'.
128
Brett Cannon6c4cff02009-03-11 04:51:06 +0000129- Issue #3652: Make the 'line' argument for warnings.showwarning() a
130 requirement. Means the DeprecationWarning from Python 2.6 can go away.
131
Eric Smithe9fb6862009-02-20 14:02:36 +0000132- Issue #5247: Improve error message when unknown format codes are
133 used when using str.format() with str, unicode, long, int, and
134 float arguments.
135
Raymond Hettinger08259e82009-02-18 23:10:19 +0000136- Running Python with the -3 option now also warns about classic division
137 for ints and longs.
138
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000139- Issue #5260: Long integers now consume less memory: average
140 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
141 on a 64-bit system.
142
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000143- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
144 rotating the object pointer by 4 bits to the right.
145
Mark Dickinsonc97c9092009-02-09 14:18:43 +0000146- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
147 it now forces its argument to double before testing for infinity.
148
Benjamin Petersone18ef192009-01-20 14:21:16 +0000149- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
150
Georg Brandl29c6a282009-04-05 20:23:13 +0000151- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000152 were suppressing all exceptions. These include list(), filter(), map(),
153 zip(), and bytearray().
154
Benjamin Peterson596d3062009-01-19 15:42:23 +0000155- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
156 functions.
157
Benjamin Peterson5848d1f2009-01-19 00:08:08 +0000158- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an
159 OSError.
160

162
Antoine Pitrouc2f02212009-01-13 23:13:52 +0000163- Issue #4935: The overflow checking code in the expandtabs() method common
164 to str, bytes and bytearray could be optimized away by the compiler, letting
165 the interpreter segfault instead of raising an error.
166
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +0000167- Issue #3720: Fix a crash when an iterator modifies its class and removes its
168 __next__ method.
169
Martin v. Löwise3422fa2009-01-12 08:11:24 +0000170- Issue #4893: Use NT threading on CE.

173
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000174- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
175 collecting the oldest generation) so that allocating lots of objects without
176 destroying them does not show quadratic performance. Based on a proposal by
177 Martin von Löwis at
178 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
179
Martin v. Löwisb90304a2009-01-07 18:40:40 +0000180- Issue #4850: Change COUNT_ALLOCS variables to Py_ssize_t.
181
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000182- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
183 an existing .py counterpart, override the co_filename attributes of all
184 code objects if the original filename is obsolete (which can happen if the
185 file has been renamed, moved, or if it is accessed through different paths).
186 Patch by Ziga Seilnacht and Jean-Paul Calderone.
187
Martin v. Löwis5344c992009-01-02 20:32:55 +0000188- Issue #4075: Use OutputDebugStringW in Py_FatalError.
189
Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +0000190- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
191 file with `str' filename on Windows.
192
Antoine Pitrouaa687902009-01-01 14:11:22 +0000193- Issue #3680: Reference cycles created through a dict, set or deque iterator
194 did not get collected.
195
Nick Coghlan180e4002008-12-30 01:18:48 +0000196- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
197 where the tp_hash and tp_dict slots are both NULL.
198
Benjamin Peterson7af65562008-12-29 17:56:58 +0000199- Issue #4764: With io.open, IOError.filename is set when trying to open a
200 directory on POSIX systems.
201
Benjamin Petersonfe231b02008-12-29 17:47:42 +0000202- Issue #4764: IOError.filename is set when trying to open a directory on POSIX
203 systems.
204
Georg Brandl6425a2f2008-12-28 11:54:53 +0000205- Issue #4759: None is now allowed as the first argument of
206 bytearray.translate(). It was always allowed for bytes.translate().
207
Skip Montanarof205c132008-12-23 03:30:15 +0000208- Added test case to ensure attempts to read from a file opened for writing
209 fail.
210
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000211- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
212 print elapsed times, not only when some objects are uncollectable /
213 unreachable. Original patch by Neil Schemenauer.
214
Mark Dickinson1a707982008-12-17 16:14:37 +0000215- Issue #3439: Add a bit_length method to int and long.
216
Antoine Pitroud0c35152008-12-17 00:38:28 +0000217- Issue #2183: Simplify and optimize bytecode for list comprehensions.
218 Original patch by Neal Norwitz.
219
Amaury Forgeot d'Arcad9b5992008-12-10 23:22:49 +0000220- Issue #4597: Fixed exception handling when the __exit__ function of a
221 context manager returns a value that cannot be converted to a bool.
222
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000223- Issue #4597: Fixed several opcodes that weren't always propagating
224 exceptions.
225
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000226- Issue #4445: Replace "sizeof(PyStringObject)" with
227 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
228 str instances. On a typical machine this saves 3 bytes of memory
229 (on average) per string allocation.
230
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000231- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
232 interpreter to abort ("Fatal Python error: Could not reset the stack!")
233 instead of throwing a MemoryError.
234
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000235- Issue #3689: The list reversed iterator now supports __length_hint__
236 instead of __len__. Behavior now matches other reversed iterators.

239 module couldn't be imported and \N escapes were present.
240
Vinay Sajip213faca2008-12-03 23:22:58 +0000241- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000242 method on file objects with closefd=False. The file descriptor is still
243 kept open but the file object behaves like a closed file. The ``FileIO``
244 object also got a new readonly attribute ``closefd``.
245
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000246- Issue #4348: Some bytearray methods returned that didn't cause any change to
247 the bytearray, returned the same bytearray instead of a copy.
248
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000249- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
250
Benjamin Peterson273c2332008-11-17 22:39:09 +0000251- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
252
Benjamin Peterson6624a9f2008-11-03 15:14:51 +0000253- Issue #4048: The parser module now correctly validates relative imports.
254
Benjamin Petersondcee09d2008-10-31 02:16:05 +0000255- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
256 exec statement.
257
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000258- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
259 method does not return iterators for the 4th and 5th items.
260
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000261- Issue #4209: Enabling unicode_literals and the print_function in the same
262 __future__ import didn't work.
263
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000264- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000265 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000266
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000267- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
268 returned a path longer than MAX_PATH. (But It's doubtful this code path is
269 really executed because I cannot move to such directory on win2k)
270
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000271- Issue #4069: When set.remove(element) is used with a set element, the element
272 is temporarily replaced with an equivalent frozenset. But the eventual
273 KeyError would always report the empty frozenset([]) as the missing key. Now
274 it correctly refers to the initial element.
275
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000276- Issue #4509: Various issues surrounding resize of bytearray objects to
277 which there are buffer exports.
278
Benjamin Peterson8d5934b2008-12-27 18:24:11 +0000279- Issue #4748: Lambda generators no longer return a value.

284
Matthias Kloseedb5e1e2009-04-04 14:18:13 +0000285- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with
286 short file names.
287
Matthias Klose91a3b9e2009-04-05 21:19:13 +0000288- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
289 to avoid compiler warnings.
Matthias Klose0610e082009-04-05 12:43:08 +0000290
Gregory P. Smith2b3eb372009-04-05 23:48:26 +0000291- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
292 returned them on 64bit platforms.
293
Walter Dörwalded960ac2009-05-03 22:36:33 +0000294- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
295 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
296 step. This avoids problems with counting UTF-8 bytes that ignores the effect
297 of using the replace error handler in PyUnicode_DecodeUTF8().
298
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000299- Issue #3739: The unicode-internal encoder now reports the number of characters
300 consumed like any other encoder (instead of the number of bytes).

1164- Issue #3850: recursion tests in Misc/find_recursion_limit.py can raise
1165 AttributeError instead of RuntimeError, depending in which C API call
1166 exactly the recursion limit is exceeded. Consequently, both exception types
1167 are caught and silenced.

1183
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001184- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1185
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001186- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1187 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1188 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1189 ``printf`` function, whereas PyString_FromFormat has an independent
1190 implementation and uses "%zd" on all platforms for size_t values.
1191 This makes a difference on win64, where ``printf`` needs "%Id" to display
1192 64bit values.
1193
Benjamin Peterson97179b02008-09-09 20:55:01 +00001194- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
1195 error.
1196
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00001197- Issue #3777: long() applied to a float object now always return a long
1198 object; previously an int would be returned for small values. the __long__
1199 method is allowed to return either an int or a long, but the behaviour of
1200 float objects should not change to respect backward compatibility.
1201
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001202- Issue #3751: str.rpartition would perform a left-partition when called with
1203 a unicode argument.
1204
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00001205- Issue #3683: Fix compilation when --without-threads is given.
1206
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001207- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00001208 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001209 was correctly parsed but parsing of subsequent arguments failed.
1210
Vinay Sajip35e3b032008-09-01 14:33:59 +00001211- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001212 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1213 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1214 when given a tuple of classes as second argument, were looking up
1215 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1216 type object.
1217
Neal Norwitz18aa3882008-08-24 05:04:52 +00001218- Fix crashes on memory allocation failure found with failmalloc.
1219
1220- Fix memory leaks found with valgrind and update suppressions file.
1221
1222- Fix compiler warnings in opt mode which would lead to invalid memory reads.
1223
1224- Fix problem using wrong name in decimal module reported by pychecker.
1225
Christian Heimes7d4c3172008-08-22 19:47:25 +00001226- Silenced another compiler warning about a used but not defined
1227 function 'stringlib_contains_obj'.

1230 ``__delslice__``.
1231
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00001232- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
1233 library targets in the Makefile.
1234
Gregory P. Smith980b99b2008-09-07 05:15:18 +00001235- Issue #1204: The configure script now tests for additional libraries
1236 that may be required when linking against readline. This fixes issues
1237 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

1259
Nick Coghland2e09382008-09-11 12:11:06 +00001260- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00001261 return a list or None rather than a custom object.
1262
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00001263- Issue #1638033: Cookie.Morsel gained the httponly attribute.

1287 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1288 for catch_warnings() also led to an improvement in the raising of a
1289 DeprecationWarning related to warnings.warn_explicit().
1290
Benjamin Peterson973e6c22008-09-01 23:12:58 +00001291- The deprecation warnings for the old camelCase threading API were removed.

1360Core and Builtins
1361-----------------
1362
Guido van Rossumf8402962008-08-20 15:01:50 +00001363- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1364 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1365 extensions do not automatically benefit from the class attribute
1366 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1367 to their tp_flags field if they care. This is a backwards
1368 compatibility feature; in 3.0, all types will use the cache by
1369 default.
1370
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001371- Keyword arguments can now follow starred arguments. (``f(a, *args,
1372 keyword=23)`` is now valid syntax.)
1373
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001374- ctypes function pointers that are COM methods have a boolean True
1375 value again.
1376
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001377- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1378 by denying s# to parse objects that have a releasebuffer procedure,
1379 and introducing s*.
1380
Georg Brandl1e13ea92008-08-11 09:07:59 +00001381- Issue #3537: Fix an assertion failure when an empty but presized dict
1382 object was stored in the freelist.
1383
Mark Dickinsonb6467572008-08-04 21:30:09 +00001384- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1385 ValueError consistently across platforms.
1386
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001387- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1388 (64bit Unix, for example), unichr() would truncate its argument and return
1389 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1390
Neal Norwitze7d8be82008-07-31 17:17:14 +00001391- Apply security patches from Apple.
1392
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001393- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1394 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1395
Antoine Pitrou92f82162008-07-25 22:22:08 +00001396- Issue #1819: function calls with several named parameters are now on
1397 average 35% faster (as measured by pybench).
1398
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001399- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1400 the python debugger steps into a class statement: the free variables (local
1401 variables defined in an outer scope) would be deleted from the outer scope.
1402
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001403- Issue #2620: Overflow checking when allocating or reallocating memory
1404 was not always being done properly in some python types and extension
1405 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1406 all been updated to perform better checks and places in the code that
1407 would previously leak memory on the error path when such an allocation
1408 failed have been fixed.

Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001413- Issue #3612: Added some missing basic types in ctypes.wintypes.
1414
Benjamin Petersone977ad42008-08-20 01:42:01 +00001415- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1416 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1417
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001418- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1419 version reported by these tools does not necessarily follow the python
1420 version numbering scheme, so the module is less strict when parsing it.
1421
Nick Coghlanf70385a2008-08-18 12:42:46 +00001422- Issue #2235: Added Py3k warnings for types which will become unhashable
1423 under the stricter __hash__ inheritance rules in 3.0. Several types
1424 which did not meet the rules for hash invariants and were already
1425 unhashable in 3.0 have now been explicitly flagged as unhashable in
1426 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1427 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1428
Brett Cannon88f801d2008-08-18 00:46:22 +00001429- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001436- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1437
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001438- Issue #3575: Incremental decoder's decode function now takes bytearray
1439 by using 's*' instead of 't#'.
1440
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00001441- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001442 fails unicode conversion on 2nd parameter. (windows only)
1443
Facundo Batista94f243a2008-08-17 03:38:39 +00001444- Issue 2464. urllib2 now supports a malformation in the URL received

1476 to _sre.compile() will now be rejected. This should not affect anybody
1477 since the re.compile() function never generates invalid re-bytecode.

Antoine Pitroude781a42008-08-09 12:43:23 +00001498 asking for a specific length. This problem only affected files opened

1526 mode 0600 rather than 000 under Unix.
1527
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001528- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

1542
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001543- Issue #643841: The language reference now provides more detailed

1551
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001552*Release date: 17-Jul-2008*

1555-----------------
1556
Georg Brandl3e483f62008-07-16 22:57:41 +00001557- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1558 its methods now allow for items objects that can be converted to
1559 an integer using operator.index().
1560
Mark Dickinson64b7e502008-07-16 09:40:03 +00001561- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1562 produced a ValueError instead of giving the correct float.
1563
Eric Smitha5fa5a22008-07-16 00:11:49 +00001564- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1565 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1566
Mark Dickinson7103aa42008-07-15 19:08:33 +00001567- Issue #3008: the float type has a new instance method 'float.hex'
1568 and a new class method 'float.fromhex' to convert floating-point
1569 numbers to and from hexadecimal strings, respectively.
1570
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001571- Issue #2235: __hash__ is once again inherited by default. To allow
1572 collections.Hashable to remain meaningful in the presence of the
1573 default hash implementation (object.__hash__), it is now possible
1574 to explicit block inheritance of hash by setting __hash__=None at
1575 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1576 level.
1577
Nick Coghlanb028f502008-07-13 14:52:36 +00001578- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1579 the parent module cannot be found while performing an absolute import.
1580 This means that an incorrectly defined __package__ attribute will
1581 now only prevent relative imports in that module rather than causing
1582 all imports from that module to fail.
1583
Nick Coghlan14ff9942008-07-08 14:21:42 +00001584- Issue #2517: Allow unicode messages in Exceptions again by correctly
1585 bypassing the instance dictionary when looking up __unicode__ on
1586 new-style classes.

1589 set to a custom object whose write() method happens to install
1590 another file in sys.stdout.

Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001592- Issue #3088: Corrected a race condition in classes derived from
1593 threading.local: the first member set by a thread could be saved in
1594 another thread's dictionary.
1595
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001596- Issue #3004: Minor change to slice.indices(): the start and stop
1597 arguments are now treated identically, making the behaviour easier
1598 to describe and understand. For example, slice(None, -10,
1599 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1600 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1601 10, -1).
1602
Georg Brandl278fc502008-07-19 12:46:12 +00001603- Issue #3219: Calling a function with repeated keyword arguments,
1604 f(a=2, a=23), would not cause a syntax error. This was a regression
1605 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001606
Georg Brandl278fc502008-07-19 12:46:12 +00001607- Issue #2862: Make int and float freelist management consistent with
1608 other freelists. Changes their CompactFreeList apis into

1615 api functions without holding the GIL, which could lead to a fatal
1616 error when they failed.
1617
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001618- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001643- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1644 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001645 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001646 content-length. The problem had been corrected in the 2.4 branch, but never
1647 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001662- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

1664
Brett Cannon8bb8fa52008-07-02 01:57:08 +00001665- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

2052
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002053- On MacOS X it is now possible to install the framework in 64-bit
2054 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002055 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002056
2057 This is controlled by the configure argument ``--with-universal-archs``:
2058
2059 - ``--with-universal-archs=all``: install 4-way universal
2060
2061 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2062
2063 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2064
2065 This option should be used in combination with ``--enable-universalsdk=``.
2066
2067 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 +00002117- Issue #1631171: Re-implement the 'warnings' module in C (the
2118 original Python code has been kept as backup). This will allow for
2119 using the 'warning's machinery in such places as the parser where
2120 use of pure Python code is not possible. Both the ``showarning()``
2121 and ``formatwarning()`` gain an optional 'line' argument which is
2122 not called by default for backwards-compatibility reasons. Setting
2123 ``warnings.showwarning()`` to an implementation that lacks support
2124 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002187- Issue #2550: The approach used by client/server code for obtaining
2188 ports to listen on in network-oriented tests has been refined in an
2189 effort to facilitate running multiple instances of the entire
2190 regression test suite in parallel without issue.
2191 test_support.bind_port() has been fixed such that it will always
2192 return a unique port -- which wasn't always the case with the
2193 previous implementation, especially if socket options had been set
2194 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2195 new implementation of bind_port() will actually raise an exception
2196 if it is passed an AF_INET/SOCK_STREAM socket with either the
2197 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2198 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2199 the socket it's been passed. This currently only applies to
2200 Windows. This option prevents any other sockets from binding to the
2201 host/port we've bound to, thus removing the possibility of the
2202 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2203 when a second SOCK_STREAM socket binds and accepts to a host/port
2204 that's already been bound by another socket. The optional preferred
2205 port parameter to bind_port() has been removed. Under no
2206 circumstances should tests be hard coding ports!
2207
2208 test_support.find_unused_port() has also been introduced, which will
2209 pass a temporary socket object to bind_port() in order to obtain an
2210 unused port. The temporary socket object is then closed and
2211 deleted, and the port is returned. This method should only be used
2212 for obtaining an unused port in order to pass to an external program
2213 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2214 a parameter to a server-oriented class that doesn't give you direct
2215 access to the underlying socket used.
2216
2217 Finally, test_support.HOST has been introduced, which should be used
2218 for the host argument of any relevant socket calls (i.e. bind and
2219 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002220
2221 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002222 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002223 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2224 test_asynchat and test_socket_ssl.
2225
Georg Brandl3ee81df2008-05-17 18:14:43 +00002226 It is now possible for multiple instances of the regression test
2227 suite to run in parallel without issue.

2494-----------------
2495
Fred Drakea8ee94b2008-03-01 02:45:07 +00002496- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002497 644. The mode is now inherited from the py file.

2500
2501- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002502
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002503- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002504 issue 215555 for a discussion.
2505
Eric Smitha73fbe72008-02-23 03:09:44 +00002506- Added the future_builtins module, which contains hex() and oct().
2507 These are the PEP 3127 version of these functions, designed to be
2508 compatible with the hex() and oct() builtins from Python 3.0. They
2509 differ slightly in their output formats from the existing, unchanged
2510 Python 2.6 builtins. The expected usage of the future_builtins
2511 module is:
2512 from future_builtins import hex, oct
2513
Eric Smith7ef40bf2008-02-20 23:34:22 +00002514- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2515 exponents for exponents with absolute value < 100. Follows C99
2516 standard. This is a change on Windows, which would use 3 digits.
2517 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2518 so that any alterations it does to the resulting string will be
2519 available in stringlib/formatter.h (for float.__format__).
2520
Eric Smith5a3c1352008-02-19 13:21:56 +00002521- Implemented PEP 3101, Advanced String Formatting. This adds a new
2522 builtin format(); a format() method for str and unicode; a
2523 __format__() method to object, str, unicode, int, long, float, and
2524 datetime; the class string.Formatter; and the C API
2525 PyObject_Format().
2526
Georg Brandl3ee81df2008-05-17 18:14:43 +00002527- Fixed several potential crashes, all caused by specially crafted
2528 __del__ methods exploiting objects in temporarily inconsistent
2529 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002530
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002531- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002532 prevent a possible crash: an Abstract Base Class would try to access
2533 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002534

Georg Brandl3ee81df2008-05-17 18:14:43 +00002538- Clear all free lists during a gc.collect() of the highest generation
2539 in order to allow pymalloc to free more arenas. Python may give back
2540 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002541
Georg Brandl3ee81df2008-05-17 18:14:43 +00002542- Issue #2045: Fix an infinite recursion triggered when printing a
2543 subclass of collections.defaultdict, if its default_factory is set
2544 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002545
Christian Heimesf75dbef2008-02-08 00:11:31 +00002546- Fixed a minor memory leak in dictobject.c. The content of the free
2547 list was not freed on interpreter shutdown.
2548
Georg Brandl3ee81df2008-05-17 18:14:43 +00002549- Limit free list of method and builtin function objects to 256
2550 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002551
Georg Brandl3ee81df2008-05-17 18:14:43 +00002552- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2553 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002554 to compact the internal free lists of pre-allocted ints and floats.
2555
Georg Brandl3ee81df2008-05-17 18:14:43 +00002556- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2557 calls. Python expected the return type int but the fork familie
2558 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002559
Georg Brandl3ee81df2008-05-17 18:14:43 +00002560- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2561 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002562
Georg Brandl3ee81df2008-05-17 18:14:43 +00002563- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2564 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002565
Georg Brandl3ee81df2008-05-17 18:14:43 +00002566- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and

Georg Brandl3ee81df2008-05-17 18:14:43 +00002569- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2570 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002571
Georg Brandl3ee81df2008-05-17 18:14:43 +00002572- Patch #1473257: generator objects gain a gi_code attribute. This is
2573 the same object as the func_code attribute of the function that
2574 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002575
Georg Brandl3ee81df2008-05-17 18:14:43 +00002576- Issue #1920: "while 0" statements were completely removed by the
2577 compiler, even in the presence of an "else" clause, which is
2578 supposed to be run when the condition is false. Now the compiler
2579 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002580
Guido van Rossumeead05f2008-01-24 18:21:02 +00002581- A few crashers fixed: weakref_in_del.py (issue #1377858);
2582 loosing_dict_ref.py (issue #1303614, test67.py);
2583 borrowed_ref_[34].py (not in tracker).
2584
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002585- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002586 suppressed while an extension is loaded by calling SetErrorMode in
2587 dynload_win.c. The error is still reported properly.
2588
Georg Brandl3ee81df2008-05-17 18:14:43 +00002589- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002590 several extension methods and modules do not work without unicode
2591 support.
2592
Georg Brandl26543b12008-01-21 18:36:51 +00002593- Issue #1882: when compiling code from a string, encoding cookies in the
2594 second line of code were not always recognized correctly.
2595
Georg Brandl14404b62008-01-19 19:27:05 +00002596- Issue #1679: "0x" was taken as a valid integer literal.
2597
Georg Brandl6caad7d2008-01-26 14:19:22 +00002598- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002599 added.
2600
Christian Heimesc94e2b52008-01-14 04:13:37 +00002601- sys.float_info / PyFloat_GetInfo: The floating point information
2602 object was converted from a dict to a specialized structseq object.
2603
Georg Brandl3ee81df2008-05-17 18:14:43 +00002604- Patch #1816: Added sys.flags structseq. It exposes the status of
2605 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002606
Georg Brandl3ee81df2008-05-17 18:14:43 +00002607- Objects/structseq.c: Implemented new structseq representation. The
2608 patch makes structseqs (e.g. the return value of os.stat) more
2609 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002610
Georg Brandl3ee81df2008-05-17 18:14:43 +00002611- Patch #1700288: added a type attribute cache that caches method
2612 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002613
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002614- Bug #1776: __import__() no longer accepts filenames on any platform.
2615 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002616

2620 envvar and sys.dont_write_bytecode attribute. All these can be set
2621 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002622
Georg Brandl3ee81df2008-05-17 18:14:43 +00002623- Improve some exception messages when Windows fails to load an
2624 extension module. Now we get for example '%1 is not a valid Win32
2625 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002626

Christian Heimes0a8143f2007-12-18 23:22:54 +00002632- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002633 and INF. float("nan"), float("inf") and float("-inf") now work on
2634 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002635
Georg Brandl3ee81df2008-05-17 18:14:43 +00002636- Compiler now generates simpler and faster code for dictionary
2637 literals. The oparg for BUILD_MAP now indicates an estimated
2638 dictionary size. There is a new opcode, STORE_MAP, for adding
2639 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002668- Patch #1739468: Directories and zipfiles containing a __main__.py
2669 file can now be directly executed by passing their name to the
2670 interpreter. The directory/zipfile is automatically inserted as the
2671 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002673- Issue #1265: Fix a problem with sys.settrace, if the tracing
2674 function uses a generator expression when at the same time the
2675 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002676
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002677- sets and frozensets now have an isdisjoint() method.
2678

2680
Neal Norwitz44f326e2007-10-05 05:29:17 +00002681- Fix warnings found by the new version of the Coverity checker.
2682
Georg Brandl3ee81df2008-05-17 18:14:43 +00002683- The enumerate() builtin function is no longer bounded to sequences
2684 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2685 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002686
Georg Brandl3ee81df2008-05-17 18:14:43 +00002687- Issue #1686386: Tuple's tp_repr did not take into account the
2688 possibility of having a self-referential tuple, which is possible
2689 from C code. Nor did object's tp_str consider that a type's tp_str
2690 could do something that could lead to an inifinite recursion.
2691 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2692 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002693
Georg Brandl3ee81df2008-05-17 18:14:43 +00002694- Issue #1164: It was possible to trigger deadlock when using the
2695 'print' statement to write to a file since the GIL was not released
2696 as needed. Now PyObject_Print() does the right thing along with
2697 various tp_print implementations of the built-in types and those in
2698 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002699
Georg Brandl3ee81df2008-05-17 18:14:43 +00002700- Issue #1147: Exceptions were directly allowing string exceptions in
2701 their throw() method even though string exceptions no longer
2702 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002703
Georg Brandl3ee81df2008-05-17 18:14:43 +00002704- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannona0c05512007-09-10 21:38:27 +00002706
Brett Cannon1e534b52007-09-07 04:18:30 +00002707- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002708 PyObject_Call() never calling back out to Python code to trigger
2709 recursion depth updates/checks. Required the creation of a static
2710 RuntimeError instance in case normalizing an exception put the
2711 recursion check value past its limit. Fixes crashers
2712 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002713

Neal Norwitz0ac60192007-05-27 04:08:54 +00002727- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002728 __*__ attributes. (Some already existed, e.g., __doc__ and
2729 __name__.)

2733
Georg Brandl2134e752007-05-21 20:34:16 +00002734- Patch #1686487: you can now pass any mapping after '**' in function
2735 calls.
2736
Collin Winter62903052007-05-18 23:11:24 +00002737- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002738 "except E as target:". This is to provide forwards compatibility
2739 with Python 3.0.

2745
Vinay Sajip8549ce32007-05-06 17:53:37 +00002746- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002747 setting a plain string, ie don't expand to single letter identifiers.
2748
Raymond Hettinger13936692007-04-11 18:40:58 +00002749- Request #1191699: Slices can now be pickled.

2753 remaining characters.
2754
Georg Brandl5cb76c12007-03-21 09:00:39 +00002755- Patch #1682205: a TypeError while unpacking an iterable is no longer
2756 masked by a generic one with the message "unpack non-sequence".
2757
Neal Norwitzaa754b72007-03-21 06:39:48 +00002758- Remove unused file Python/fmod.c.
2759
Guido van Rossum143b5642007-03-23 04:58:42 +00002760- Bug #1683368: The object.__init__() and object.__new__() methods are
2761 now stricter in rejecting excess arguments. The only time when
2762 either allows excess arguments is when it is not overridden and the
2763 other one is. For backwards compatibility, when both are
2764 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002765 warning later). Also, type.__init__() insists on the same signature
2766 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00002768- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2769 object to complex using its __complex__() method before falling back
2770 to the __float__() method. Therefore, the functions in the cmath
2771 module now can operate on objects that define a __complex__()
2772 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002794 its argument, if it exists. If not, it will work like before. This
2795 allows customizing the output of dir() in the presence of a

Georg Brandlaa2321b2007-03-07 00:40:28 +00002808- Patch #703779: unset __file__ in __main__ after running a file. This

Georg Brandl2c1375c2006-10-12 11:27:59 +00002878- Bug #1545497: when given an explicit base, int() did ignore NULs
2879 embedded in the string to convert.
2880
Georg Brandl846f73a2006-10-08 07:11:54 +00002881- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl4e933132006-09-06 20:05:58 +00002911- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002929 generator expressions (x for x, in ... ) works again. Fixing this
2930 problem required changing the .pyc magic number. This means that
2931 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003320 the client's request was successfully received, understood, and

Georg Brandl3ee81df2008-05-17 18:14:43 +00003361 AttributeError instead of an IOError when the server's response
3362 didn't contain a valid HTTP status line.

3394
Georg Brandl92a6bae2007-03-13 17:43:32 +00003395- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003396 are set for invalid interpolation sequences that would lead to
3397 errors on reading back those values.

3453 TestCase and TestSuite subclasses (not instances) are no longer

3828 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3829 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00003846 time so that opening a database previously created with the DB_DUP
3847 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3848 opens. Specifically: dictionary assignment to a DB object will
3849 replace all values for a given key when the database allows
3850 duplicate values. DB users should use DB.put(k, v) when they want
3851 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003852

3858 characters with ASCII value less than 32. Also, it correctly quotes
3859 dots only if they occur on a single line, as opposed to the previous
3860 behavior of quoting dots if they are the second character of any
3861 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003862
